Description

Configuration information processing method and device, base station, terminal

Technical field

The present disclosure relates to the field of communications technologies, and, for example, to a configuration information processing method and apparatus, a base station, and a terminal.

Background technique

Long Term Evolution (LTE) and Long Term Evolution (LTE-A) technologies are the mainstream fourth-generation mobile communication technologies (4G). LTE and LTE-A are usually divided into two different duplex modes: Frequency Division Duplex (FDD) and Time Division Duplex (TDD). The frame structure of the frequency division duplex mode is called a frame structure type 1 (Frame structure type 1), and the frame structure of the time division duplex mode is called a frame structure type 2 (Frame structure type 2).

FIG. 1 is a schematic diagram of a first type of frame structure. As shown in FIG. 1, the description of the first type of frame structure is as follows: each radio frame has a length of T _f =307200·T _s =10 ms (milliseconds), and is composed of 20 slots. The length is T _slot = 15360 · T _s = 0.5ms (milliseconds), numbered from 0 to 19, where Ts is the time unit, T _s =1 / (15000 × 2048) seconds; the subframe is defined as It is composed of two consecutive time slots, that is, the subframe i is composed of the time slots 2i and 2i+1; for the FDD duplex mode, in the 10 millisecond time interval, 10 subframes are used for downlink transmission, and 10 subframes are used for uplink. The uplink transmission and the downlink transmission are performed on different frequencies respectively. In the half-duplex FDD mode, the terminal (User Equipment, UE) cannot transmit and receive at the same time, but in the full-duplex FDD mode. There is no such restriction.

2 is a schematic diagram of a second type of frame structure. As shown in FIG. 2, the description of the second type of frame structure is as follows: each radio frame has a length of T _f =307200·T _s =10 ms, and is composed of two half frames (half-frame), and the length of the field is half frame length. 153600·T _s =5ms, each field consists of 5 subframes, each subframe has a length of 30720·T _s =1ms, and each subframe is defined as two slots, that is, a subframe. i is composed of time slots 2i and 2i+1, and the time slot length is T _slot = 15360 · T _s = 0.5 ms, where Ts is a time unit and T _s = 1 / (15000 × 2048) seconds.

The uplink-downlink configuration change of a cell occurs between frames, and the uplink and downlink transmission occurs on a subframe of a frame. The uplink and downlink configuration of the current frame is obtained by high layer signaling.

There are 7 types of uplink-downlink configuration shown in Table 1. For each subframe in a radio frame, "D" marks a downlink subframe for downlink transmission, and "U" marks an uplink sub-frame. Frame for uplink transmission, "S" for a special subframe. The special subframe has the following three areas: a downlink pilot time slot (DwPTS), a guard interval (GP), and an uplink pilot time slot (UpPTS).

Table 1

The downlink transmission of LTE and LTE-A technologies adopts Orthogonal Frequency Division Multiplexing (OFDM) modulation technology, and data is modulated on a subcarrier of a frequency domain, and then converted to a time domain to add a cyclic prefix to form a subcarrier. The complete time domain transmits OFDM symbols. A cyclic prefix (CP) is used to resist symbol interference generated by multipath in the time domain and inter-subcarrier interference generated in the frequency domain. There are two types of CPs in the LTE and LTE-A systems, one is a normal cyclic prefix (NCP) and the other is an extended cyclic prefix (ECP). Extended CP applications are used in scenarios where multipath delays are extended. In the case of a normal CP, the subcarrier spacing is 15 kHz; in the case of an extended CP, there are two subcarrier spacings, 15 kHz and 7.5 kHz, respectively.

The signal transmitted in each time slot is described by one or more resource grids, and the resource grid is composed of

Subcarriers and

OFDM symbols are constructed. among them,

Represents the number of Physical Resource Blocs (PRBs) or Resource Blocks (RBs),

Represents the number of subcarriers in the resource block,

Represents the number of OFDM symbols in a slot. Table 2 shows the physical resource block parameters. The number of OFDM symbols and the number of subcarriers on one RB are shown in Table 2. Table 3 shows the OFDM symbol parameters, and the length of the cyclic prefix is as shown in Table 3.

Table 2

table 3

Number of physical resource blocks

It is determined by the downlink transmission bandwidth configured by the cell, and has a minimum value of 6 and a maximum value of 110.

The same PRB on two consecutive time slots in the same subframe is called a PRB pair.

3 is a schematic diagram of a downlink resource grid. As shown in FIG. 3, each unit in the resource grid is called a resource element (Resource Element, RE), and is marked with an index pair (k, l), where

Indicates the subcarrier number in the frequency domain.

Indicates the OFDM symbol number in the time domain.

An antenna port is defined as the channel through which symbols transmitted on this antenna port pass, and can be guessed by the channel through which other symbols transmitted on the same port pass. An antenna port is also defined with a corresponding sequence number for distinguishing between antenna ports and as an index of the antenna port.

The Downlink Physical Channel corresponds to a set of resource units for carrying information from the upper layer. The downlink physical channel includes: a Physical Downlink Shared Channel (PDSCH), a Physical Multicast Channel (PMCH), a Physical Broadcast Channel (PBCH), and a Physical Control Format Indicator Channel (Physical Control Format). Indicator Channel (PCFICH), Physical Downlink Control Channel (PDCCH), Physical Hybrid ARQ Indicator Channel (PHICH), and Enhanced Physical Downlink Control Channel (EPDCCH) ).

The downlink physical signal (Downlink Physical Signal) corresponds to a set of resource elements, which are used by the physical layer and are not used to carry upper layer information. The downlink physical signals include: a reference signal (RS), a synchronization signal (Synchronization signal), and a discovery signal (Discovery signal).

The pilot signal is also called a pilot, and has the following types: Cell-specific Reference Signal (CRS), Multicast Broadcast Single Frequency Network (MBSFN) pilot (MBSFN reference signals) , UE-specific pilot (Demodulation Reference Signal (DMRS)), positioning pilot signal (CSI reference signal), and CSI reference signal (CSI-RS). The UE-specific pilots have the following two types: UE-specific reference signals associated with PDSCH and Demodulation reference signals associated with EPDCCH.

Channel State Information Pilot (CSI-RS) is used by the terminal to predict the channel state. A CSI-RS that uses non-zero power transmission is called a non-zero power CSI-RS (NZP CSI-RS); sometimes to avoid interference, it is necessary to avoid data transmission on some REs on the PDSCH, and use zero-power transmission CSI-RS. The mode is implemented as a zero-power CSI-RS (ZP CSI-RS), and the corresponding resource unit set is a Zero Power CSI-RS Resource. Sometimes, in order to measure interference, a CSI-RS is transmitted with zero power, and the corresponding resource unit set is called a Channel-State Information-Interference Measurement Resource (CSI-IM Resource).

The channel state information pilot configuration, that is, the CSI-RS configuration is used to indicate the RE mapped by the CSI-RS, that is, the RE used for transmitting the CSI-RS, and the CSI-RS configuration sequence number is used. To distinguish between different CSI-RS configurations. A CSI reference signal subframe configuration is used to indicate a subframe in which a CSI-RS transmission is located.

A CSI-RS configuration is a CSI-RS configuration with a certain number of antenna ports, for example, a CSI-RS configuration with a configuration number of 0 with an antenna port number of 8. Usually the serial number is the index number.

The related art supports CSI-RSs having a port number of 1, 2, 4, 8, 12, and 16, and the number of CSI-RS resource unit patterns of these port numbers is repeated on each PRB pair of the bandwidth range of the transmission subframe.

The CSI-RS resource with the port number of 1, 2, 4, and 8 is composed of a single CSI-RS resource, and the CSI-RS resources with the port number of 12 and 16 are configured by multiple CSI-RSs. Aggregated.

The base station or the terminal usually measures the channel state through a channel state measurement process (CSI Process). One CSI-RS resource is usually configured in one CSI process, and the terminal feeds back according to the measurement of the CSI-RS.

4 is a resource unit pattern of a CSI-RS with a port number of 4 on one RB pair; FIG. 5 is a resource unit pattern of a CSI-RS with a port number of 8 on one RB pair.

In order to make full use of power and improve the accuracy of channel measurement, the ports are divided into multiple groups, and the ports in the group are code division multiplexed.

The base station notifies the terminal about the CSI-RS by using upper layer signaling, and the information includes: a CSI-RS resource configuration identifier, a CSI-RS port number, a CSI-RS configuration, and a CSI-RS subframe. Configuration.

The CRS can be used for both channel state measurement and channel coefficient estimation when receiving demodulation, but as the number of ports increases, the overhead increases dramatically. Therefore, when the number of ports is 8, the CRS is no longer used to measure the channel state, and the CSI-RS with low pilot density and low overhead is used instead. However, as technology and demand evolve, there is a need to develop techniques for applying a greater number of antenna ports, such as the number of ports 20, 24, 28, and 32, and to measure channel states for a greater number of ports. In the case of an increase in the number of ports, the transmission power allocated to each port is reduced, the coverage of the pilot is reduced, and the signal to interference and noise ratio value is reduced, thereby reducing the quality of the channel measurement. By using code division multiplexing to transmit pilots, the adverse effects due to port power reduction can be reduced. A technique of code division multiplexing length 2 and a code division multiplexing length of 4 have been supported in the related art, but when transmitting CSI-RSs of more ports, for example, when the number of ports is 20, 24, 28 or 32 , still can not fully use the power.

The CSI-RS transmission technology with a code division multiplexing length of 8 can fully utilize the power and improve the performance of the channel measurement. However, the following problems exist: the number of resource unit patterns required to support the configuration of the base station or the terminal is too large, or the base station or the base station or The CSI-RS transmission supported by the terminal has too many categories, or the signaling overhead is too large, or the density category supporting the transmission is insufficient, or the rate matching of the legacy terminal is not compatible.

An effective solution has not been proposed for the problem that the channel state information pilot CSI-RS transmission complexity is high.

In this embodiment, a method for processing configuration information of a channel state information pilot resource is provided. FIG. 6 is a flowchart of a method for processing configuration information of a channel state information pilot resource according to the embodiment. As shown in FIG. The process includes the following steps:

In step 602, configuration information of a channel state information pilot resource is determined, where the configuration information includes at least one of: a code division multiplexing type of the channel state information pilot resource, and a port of the channel state information pilot resource. a number, a density of the channel state information pilot resource, a sequence number of a channel state information pilot configuration for aggregating the channel state information pilot resource, and an offset position of the channel state information pilot configured in the frequency domain; The resource unit pattern of the channel state information pilot configuration is determined by at least the code division multiplexing class and the sequence number.

In step 604, signaling containing the configuration information is generated and the signaling is sent.

Determining configuration information of the channel state information pilot resource by the base station, where the configuration information includes at least one of: a code division multiplexing type of the channel state information pilot resource, a port number of the channel state information pilot resource, and the The density of the channel state information pilot resource, the sequence number of the channel state information pilot configuration used for the channel state information pilot resource, and the offset position of the channel state information pilot configured in the frequency domain; the channel state information The resource unit pattern of the pilot configuration is determined by at least the code division multiplexing category and the sequence number; the signaling including the configuration information is generated according to the configuration information of the channel state information pilot resource, and the signaling is sent, and the solution is solved. In the related art, the channel state information pilot CSI-RS transmission has a high complexity, and the effect of reducing the channel state information pilot CSI-RS transmission complexity is achieved.

In an embodiment, the resource unit pattern of the channel state information pilot configuration is determined in combination by at least the number of ports of the code division multiplexing class, the sequence number, and the channel state information pilot configuration.

In an embodiment, in the case that the code division multiplexing length is 8, the channel state information pilot resource is obtained by a continuous sequence number channel state information pilot configuration aggregation; and is used for aggregation to obtain the channel state information pilot resource. The channel state information pilot configuration may be referred to as a candidate channel state information pilot configuration. The candidate channel state information pilot configuration may include multiple candidate types, wherein the channel state information pilot configuration port number of each candidate type is different, and the channel state information pilot resource whose port number is M is configured to be configured by The channel state information pilot configuration of one of the candidate types is aggregated, and M is a positive integer.

Among the above various candidate types, there is one candidate type of channel state information pilot configuration consisting of 4 resource unit patterns having a code division multiplexing length of 8. Alternatively, among the plurality of candidate types, there is one candidate type of channel state information pilot configuration consisting of three resource unit patterns having a code division multiplexing length of 8. Alternatively, among the plurality of candidate types, there is one candidate type of channel state information pilot configuration consisting of two resource unit patterns having a code division multiplexing length of 8.

In an embodiment, the sequence number is determined by the number of ports configured by the channel state information pilot, wherein the channel state information pilot configuration with a larger number of ports has a smaller sequence number value, and the channel number information has a smaller number of channel state information pilot configurations. The sequence number value of the channel state information pilot configuration with a large number of ports is large, and the sequence number value of the channel state information pilot configuration with a small number of ports is small.

That is, the larger the number of ports, the smaller the sequence number value of the channel state information pilot configuration, or the smaller the number of ports, the larger the sequence number value of the channel state information pilot configuration.

The offset position is determined by at least the number of ports of the code division multiplexing class and the channel state information pilot configuration.

The above density is determined by at least the number of ports of the code division multiplexing class and the channel state information pilot configuration.

In an embodiment, in a candidate channel state information pilot configuration of the same number of ports, there may be L channel state information pilot configurations having K identical resource unit patterns having a code division multiplexing length of 8, wherein L is an integer greater than or equal to 2, and K is an integer greater than or equal to 1.

This embodiment will be exemplified in conjunction with the following examples. The following examples are intended to illustrate and explain the invention and are not intended to limit the invention.

FIG. 7 is a flowchart of a method for transmitting channel state information pilot CSI-RS configuration information according to an embodiment. As shown in FIG. 7, the method for transmitting configuration information of a channel state information pilot resource provided by this embodiment includes the following steps:

In step 702, the base station determines configuration information of the channel state information pilot resource CSI-RS;

In step 704, the base station generates signaling including configuration information of the channel state information pilot resource;

In step 706, the base station transmits signaling of the configuration information including the channel state information pilot resources.

The configuration information of the channel state information pilot resource may include at least one of: a channel state information pilot code division multiplexing class, a port number of the channel state information pilot resource, a density of the channel state information pilot resource, The sequence number of the channel state information pilot configuration used to aggregate the channel state information pilot resources and the channel state information pilot are arranged in an offset position in the frequency domain.

The resource unit pattern of the foregoing configuration is determined by at least a combination of a code division multiplexing category and a sequence number of the configuration.

In this embodiment, the channel state information pilot resources are obtained by the channel state information pilot configuration, for example, may be aggregated by one channel state information pilot configuration, or may be aggregated by multiple channel state information pilot configurations; The resource unit pattern of the channel state information pilot configuration may be determined by the code division multiplexing class and the channel state information pilot configuration sequence number. That is, the same channel state information pilot configuration sequence number, the resource unit pattern of the channel state information pilot configuration corresponding to different code division multiplexing classes is independent, and may be different resource unit patterns. In this way, the class of the code division multiplexing is used to distinguish the resource unit patterns of different channel state information pilot configurations, so that it is not necessary to allocate a large number of different sequence numbers for the resource unit patterns of a large number of different channel state information pilot configurations, thereby saving signaling. Overhead. In the case where the code division multiplexing class participates in determining the resource element pattern of the channel state information pilot configuration, the base station or terminal can reduce the retrieval complexity of the resource unit pattern for the predefined channel state information pilot configuration. For example, in the case where the code division multiplexing class is determined, the resource unit pattern of the channel state information pilot configuration corresponding to the code division multiplexing class may be preloaded without loading all the predefined channel state information pilots. The configured resource unit pattern.

In an embodiment, the configured resource unit pattern is determined in combination by at least a code division multiplexing class, a sequence number of the configuration, and a port number of the channel state information pilot resource.

The resource element patterns of the channel state information pilot resources corresponding to different port numbers may be different, so that the number of pilot resource ports of the channel state information is used to help distinguish the resource unit patterns of different channel state information pilot configurations, so that A large number of different channel state information pilot configuration resource unit patterns are assigned a large number of different sequence numbers, which can save signaling overhead. Similarly, the base station or terminal can reduce the retrieval complexity of the resource unit pattern for the predefined channel state information pilot configuration. For example, in the case where the number of channel state information pilot resource ports is determined, the resource unit pattern of the channel state information pilot configuration corresponding to the number of channel state information pilot resource ports is preloaded without loading all the predefined Resource unit pattern of channel state information pilot configuration.

In an embodiment, in the case that the code division multiplexing length is 8, the channel state information pilot resource is obtained by a continuous sequence number channel state information pilot configuration aggregation.

The channel state information pilot resources that are not aggregated by any channel state information pilot configuration have the same performance, some combination performance is higher, some combination performance is lower, and channel state information guidance with high combination performance is given. The frequency configuration allocates consecutive sequence numbers, and the channel state information pilot resources are aggregated by the continuous sequence number channel state information pilot configuration, which can achieve higher performance and reduce the complexity of the base station to retrieve the high performance configuration combination. The complexity of the terminal to find the configuration combination can be reduced, and the signaling overhead can also be saved.

In an embodiment, in the case that the code division multiplexing length is 8, the candidate channel state information pilot configuration may include multiple types, the number of ports of each type of the configuration is different, and the channel number is M. The information pilot resource can be configured to be aggregated by any of the candidate types, M being a positive integer.

The code division multiplexing length is 8 to aggregate the channel state information pilot resources with a relatively large number of ports, for example, to aggregate channel state information pilot resources of 24 ports, and then, for example, aggregate channel state information of 32 ports. The frequency resource is aggregated by using a channel state information pilot configuration with a large number of ports, which can reduce the number of channel state information pilot configurations used, and bind the resource unit combination pattern with higher performance, thereby reducing signaling. The overhead, reducing the complexity of the base station to retrieve the resource unit combination pattern with high performance, and reducing the complexity of the UE detecting the resource unit combination pattern.

For example, the 32-port channel state information pilot resources are aggregated by the 32-port channel state information pilot configuration. For example, the channel state information pilot resources of 24 ports are aggregated by the channel state information pilot configuration of 24 ports. However, in the case of data transmission by a conventional terminal, the channel state information pilot configuration with a large number of ports is used for aggregation. If low-density transmission is used, the rate matching of data transmission of the legacy terminal cannot be balanced. The aggregation of the channel state information pilot configuration with a small number of ports can balance the rate matching of the data transmission of the legacy terminal. The channel state information pilot resources with the number of ports M can be configured to be aggregated by the channel state information pilot configuration of one of the candidate types. The channel state information pilots of different candidate types are configured with different numbers of ports, which can be flexible. It can reduce the complexity of the system (base station and terminal), and can also balance the rate matching of the traditional terminal when transmitting data in the traditional terminal.

In an embodiment, a candidate type of configuration may be composed of 4 resource unit patterns having a code division multiplexing length of 8. For example, channel state information pilot resources of 32 ports can be aggregated by such a channel state information pilot configuration, and channel state information pilot resources of 24 ports can also be aggregated by such a channel state information pilot configuration. . It is possible to reduce the number of channel state information pilot configurations used, and to bind the resource unit combination pattern with higher performance, thereby reducing signaling overhead and reducing the complexity of the base station retrieving the resource unit combination pattern with high performance. The complexity of detecting the resource unit combination pattern by the UE may also be reduced.

In an embodiment, a configuration of the candidate type is composed of two resource unit patterns having a code division multiplexing length of 8. For example, the channel state information pilot resources of the 32 ports can be obtained by the aggregation of the two channel state information pilot configurations; especially in the case of 1/2 density, the aggregation of the two channel state information pilot configurations is obtained. However, the configured offset positions are different, for example, the offset positions of the two channel state information pilot configurations in the frequency domain are 0 and 1, respectively. In such a low-density case, the number of configurations used for aggregation can be reduced to some extent, and the rate matching of the legacy terminal can be taken into consideration.

In an embodiment, a configuration of the candidate type is composed of 3 resource unit patterns of code division multiplexing length 8; for example, channel state information pilot resources of 24 ports may be composed of such channel status information. Pilot configuration aggregation. In this way, the number of channel state information pilot configurations used can be reduced, and the resource unit combination pattern with higher performance is bound, thereby reducing signaling overhead and reducing the complexity of the base station retrieving the resource unit combination pattern with high performance. Degree, reducing the complexity of the UE detecting the resource unit combination pattern.

In an embodiment, the sequence number of the channel state information pilot configuration may be determined by the number of ports configured by the channel state information pilot, wherein the sequence number value of the configuration with a larger number of ports is smaller, and the sequence number value of the configuration with a smaller number of ports is larger. Or, the configuration with a larger number of ports has a larger sequence number value, and the configuration with a smaller number of ports has a smaller sequence number value. That is, the larger the number of ports, the smaller the sequence number value of the configuration, or the larger the number of ports, the larger the sequence number value of the configuration.

The channel state information pilot resource of one port number is aggregated by using the channel state information pilot configuration, and the number of ports configured for the channel state information pilots participating in the aggregation is the same; the channel number information pilot configuration with the same number of ports is assigned consecutive numbers. The complexity of the base station can be reduced, the complexity of the terminal can be reduced, and the signaling overhead can be reduced. In a scenario where there are many new terminals, the frequency of the channel state information pilot configuration with a larger number of ports is higher, and the port is used. The number of channel state information pilot configurations is assigned a smaller number, which can reduce the signaling overhead, reduce the complexity of the base station retrieval, and reduce the complexity of terminal detection. The data is transmitted frequently in traditional terminals. In the scenario, the channel state information pilot configuration with a smaller number of ports can allocate a smaller sequence number, which can reduce signaling overhead, reduce the complexity of base station retrieval, and reduce the complexity of terminal detection.

In an embodiment, the offset position of each channel state information pilot configuration may be determined according to the type of code division multiplexing described above and the number of ports configured for each channel state information pilot.

The resource unit pattern of the channel state information pilot configuration of different port numbers is different when the code division multiplexing length is 2, and the resource unit of the channel state information pilot configuration of different port numbers in the case where the code division multiplexing length is 4 If the patterns are different, the resource unit patterns of the channel state information pilot configurations of different port numbers are different in the case where the code division multiplexing length is 8.

In the case where the code division multiplexing length is 8, the channel state information pilot configuration used by different port numbers is different. For example, the channel state information pilot configuration with a large number of ports can be used in a high density case. Can be used in low-density situations; the channel state information pilot configuration with a small number of ports can only be used in low-density situations; for example, 32-port channel state information pilot resources can be used by a 32-port channel The status information pilot configuration aggregation, the offset position of the configuration in the frequency domain may be 0, or 1, or 2; the channel state information of 32 ports may also be composed of channel information of two 16 ports. Pilot configuration aggregation, where one configuration has an offset position of 0 and another configuration has an offset position of 1. The resource unit patterns of the two configurations may be the same or different; channel status of 24 ports The information pilot resource may be aggregated by a channel state information pilot configuration of one 24 ports, and the offset position of the configuration in the frequency domain may be 0, or 1, or 2; channel shape of 24 ports The information pilot resource can also be aggregated by three 8-port channel state information pilot configurations, where one configuration has an offset position of 0, another configuration has an offset position of 1, and the remaining configuration has an offset position of 2 The resource unit patterns of the three configurations may be the same or different. In the case where the code division multiplexing length is 2 or 4, the offset position of the channel state information pilot configuration of the different port numbers is different from the case where the above-mentioned division multiplexing length is 8.

Determining the configured offset position by the code division multiplexing type and the configured number of ports can save the signaling overhead of the offset location, avoid the operation of the base station to prepare multiple offset positions, can reduce the complexity of the base station, and avoid the terminal preparation. The operation of the offset position can reduce the complexity of the terminal.

In an embodiment, the number of ports of the channel state information pilot resource, the type of code division multiplexing, and the number of ports of the channel state information pilot configuration are jointly determined to determine the offset position of the channel state information pilot configuration.

Wherein, in the case that the code division multiplexing length is 8, for example, the channel state information pilot resources of 32 ports may be aggregated by a channel state information pilot configuration of one 32 ports, and the configuration is in the offset position of the frequency domain. 0, or 1, or 2; 32-port channel state information pilot resources can also be aggregated by two 16-port channel state information pilot configurations, one of which has an offset position of 0 and another The configured offset location is 1, and the resource unit patterns of the two configurations may be the same or different; the channel state information of the 24 ports may be guided by the channel state information of one 24 ports. Configure the aggregation. The offset position of the configuration in the frequency domain is 0, or 1, or 2; the channel state information of the 24 ports. The pilot resource can also be aggregated by the channel state information pilot configuration of three 8 ports. One of the configured offset positions is 0, the other configuration has an offset position of 1, and the remaining one has an offset position of 2. The three configured resource unit patterns may be the same or different. In the case where the code division multiplexing length is 2 or 4, the offset position of the channel state information pilot configuration of different port numbers is different from the case where the above-mentioned division multiplexing length is 8.

The number of ports of the channel state information pilot resource, the type of code division multiplexing, and the number of ports configured by the channel state information pilot are jointly determined to determine the offset position of the channel state information pilot configuration, which can save signaling overhead of the offset position. The operation of the base station to avoid various offset positions is avoided, the complexity of the base station can be reduced, the operation of the terminal to prepare various offset positions can be avoided, and the complexity of the terminal can be reduced.

In an embodiment, the type of code division multiplexing is combined with the configured number of ports to determine the density of the resource.

The different code division multiplexing and the number of ports configured by the channel state information pilot correspond to different channel state information pilot resource density ranges; the channel is determined by the number of code division multiplexing and the number of ports configured by the channel state information pilot. The density of the status information pilot resources can save the signaling overhead of the offset location, avoid the base station preparing multiple density operations, reduce the complexity of the base station, avoid the terminal to prepare multiple density operations, and reduce the complexity of the terminal.

For example, if the code division multiplexing length is 2 or 4, the resource density corresponding to the channel state information pilot configuration of all port numbers may be 1, 1/2 or 1/3. In the case where the code division multiplexing length is 8, for example, the channel state information pilot resources of 32 ports are aggregated by a channel state information pilot configuration of one 32 ports, and the density may be 1, 1/2 or 1/3; The channel state information pilot resources of 32 ports are aggregated by two 16-port channel state information pilot configurations, and the density may be 1/2. The resource unit patterns of the two configurations may be the same or different. ; 24 port channel state information pilot resources are aggregated by a channel state information pilot configuration of 24 ports, the density can be 1, 1/2 or 1/3; 24 port channel state information pilot resources by The channel state information pilot configuration of three 8-ports is aggregated, and the density may be 1/3. The resource unit patterns of the three configurations may be the same or different.

In an embodiment, the density of the channel state information pilot resources may be jointly determined by the number of ports of the channel state information pilot resources, the type of code division multiplexing, and the number of ports of the channel state information pilot configuration.

The number of ports of the channel state information pilot resource, the number of different code division multiplexing and the number of ports configured by the channel state information pilot correspond to different channel state information pilot resource density ranges; the number of ports of the channel state information pilot resources The type of the code division multiplexing and the number of ports of the channel state information pilot configuration jointly determine the density of the channel state information pilot resources, which can save the signaling overhead of the above offset position, and avoid the base station preparing multiple density operations, which can be reduced. The complexity of the base station prevents the terminal from preparing for multiple density operations, which can reduce the complexity of the terminal.

In an embodiment, among the candidate channel state information pilot configurations of the same number of ports, there may be L channel state information pilot configurations, and the L channel state information pilot configurations may have K identical code division multiplexing. a resource unit pattern of length 8, wherein L is an integer greater than or equal to 2, and K is an integer greater than or equal to 1.

The partial resource unit patterns of the multiple channel state information pilot configurations may also overlap, and a larger number of channel state information pilot configurations may be constructed, so that more high performance configuration combinations may be selected to be aggregated into channel state information guides. Frequency resources.

FIG. 8 is a structural block diagram of an apparatus for transmitting channel state information pilot configuration information according to the embodiment. As shown in FIG. 8, the apparatus may be applied to a base station side, and includes: a configuration module 82 configured to determine a channel state information pilot. The configuration information of the resource is generated, and the generating module 84 is coupled to the configuration module 82, and configured to generate signaling that includes configuration information of the channel state information pilot resource. The sending module 86 is coupled to the generating module 84 and configured to send signaling. The configuration information of the channel state information pilot resource includes at least one of the following: a channel state information pilot code division multiplexing class, a channel state information pilot resource port number, and a channel state information pilot resource density. The sequence number of the channel state information pilot configuration aggregated into the channel state information pilot resource and the channel state information pilot are arranged in an offset position in the frequency domain.

The resource unit pattern of the channel state information pilot configuration is determined by at least a combination of a code division multiplexing type and a sequence number of the channel state information pilot configuration.

In this embodiment, the channel state information pilot resources are obtained by the channel state information pilot configuration, for example, may be obtained by a channel state information pilot configuration aggregation, or may be aggregated by multiple channel state information pilot configurations. The resource unit pattern of the channel state information pilot configuration may be determined by the class of the above code division multiplexing and the sequence number of the channel state information pilot configuration. That is, the same channel state information pilot configuration sequence number, the resource unit pattern of the channel state information pilot configuration corresponding to different code division multiplexing classes is independent, and may be different resource unit patterns. In this way, the resource unit pattern of different channel state information pilot configurations is distinguished by using the class of code division multiplexing, so that it is not necessary to allocate a large number of different sequence numbers for the resource unit patterns of a large number of different channel state information pilot configurations, so that the letter can be saved. Make the cost. In the case where the code division multiplexing class participates in determining the resource element pattern of the channel state information pilot configuration, the base station or terminal may reduce the retrieval complexity of the resource unit pattern for the predefined channel state information pilot configuration. For example, in the case where the code division multiplexing class is determined, the resource unit pattern of the channel state information pilot configuration corresponding to the code division multiplexing class may be preloaded without loading all the predefined channel state information pilots. The configured resource unit pattern.

In an embodiment, the resource unit pattern of the channel state information pilot configuration is determined by at least the foregoing code division multiplexing class, the sequence number of the channel state information pilot configuration, and the number of ports of the channel state information pilot resource.

The resource element pattern of the channel state information pilot resource corresponding to the different port number is different, and the resource element pattern of the channel state information pilot configuration may be distinguished by using the channel state information pilot resource port number, so that it is not necessary for a large number of The resource unit patterns of different channel state information pilot configurations are allocated a large number of different sequence numbers, which can save signaling overhead. Similarly, the base station or terminal can reduce the retrieval complexity of the resource unit pattern for the predefined channel state information pilot configuration. For example, in the case where the number of channel state information pilot resource ports is determined, the resource unit pattern of the channel state information pilot configuration corresponding to the number of channel state information pilot resource ports is preloaded without loading all the predefined Resource unit pattern of channel state information pilot configuration.

In an embodiment, in the case where the code division multiplexing length is 8, the channel state information pilot resources are aggregated by the consecutive sequence number channel state information pilot configurations.

The channel state information pilot resources that are not arbitrarily configured and aggregated have the same performance, some combination performance is higher, some combination performance is lower, and a continuous sequence number is assigned to the configuration with high combination performance, and then the channel state is The information pilot resource is aggregated by the configuration of consecutive serial numbers, which can achieve higher performance, reduce the complexity of the base station to retrieve the high-performance configuration combination, reduce the complexity of the terminal to find the configuration combination, and save the letter. Make the cost.

In an embodiment, in the case that the code division multiplexing length is 8, the candidate channel state information pilot configuration includes multiple types, and the number of ports of each type of the configuration is different, and the channel state information of the port number is M. The pilot resources can be configured to be aggregated by a channel state information pilot configuration of one of any candidate types, M being a positive integer.

The code division multiplexing length is 8 to aggregate the channel state information pilot resources with a relatively large number of ports, for example, to aggregate channel state information pilot resources of 24 ports, for example, to aggregate channel state information pilot resources of 32 ports. Aggregation using a channel state information pilot configuration with a large number of ports can reduce the number of configurations used and bind resource element combination patterns with higher performance, thereby reducing signaling overhead and reducing base station retrieval. The complexity of the resource unit combination pattern of performance reduces the complexity of the UE detecting the resource unit combination pattern. For example, the 32-port channel state information pilot resources are aggregated by the 32-port channel state information pilot configuration. For example, the channel state information pilot resources of 24 ports are aggregated by the channel state information pilot configuration of 24 ports. However, in the case where the legacy terminal simultaneously transmits data, the configuration aggregation with a large number of ports is adopted, and if the low-density transmission is adopted, the rate matching of the data transmission of the legacy terminal cannot be taken into consideration. The configuration aggregation with a small number of ports can balance the rate matching of data transmission of the legacy terminal. The channel state information pilot resource with the number of ports M may be configured to be aggregated by the channel state information pilot configuration of one of the candidate types, and the number of ports configured by different candidate types is different, and the system can be flexibly supported to reduce the system (base station and Terminal) complexity, and can also balance the rate matching of traditional terminals when transmitting data in a traditional terminal.

In an embodiment, a candidate type of channel state information pilot configuration is composed of 4 resource unit patterns having a code division multiplexing length of 8.

The channel state information pilot resources of, for example, 32 ports may be aggregated by such a configuration, and the channel state information pilot resources of the 24 ports may also be aggregated by such a configuration. In this way, the number of configurations used can be reduced, and the resource unit combination pattern with higher performance is bound, thereby reducing the signaling overhead, reducing the complexity of the base station retrieving the resource unit combination pattern with high performance, and reducing the UE detection. The complexity of the resource unit combination pattern.

In one embodiment, a candidate type of channel state information pilot configuration is comprised of two resource element patterns having a code division multiplexing length of eight.

Wherein, for example, channel state information pilot resources of 32 ports can be aggregated by such two configurations; in particular, in the case of 1/2 density, two identical configurations are aggregated, but the configured offset positions are different, for example, respectively It is 0,1. In such a low-density case, the number of configurations used for aggregation can be reduced to some extent, and the rate matching of the legacy terminal can be taken into consideration.

In an embodiment, a candidate type channel state information pilot configuration is composed of three resource unit patterns having a code division multiplexing length of 8;

The channel state information pilot resources of the 24 ports may also be aggregated by such a configuration. In this way, the number of configurations used is reduced, and the resource unit combination pattern with higher performance is bound, thereby reducing signaling overhead, reducing the complexity of the base station retrieving the resource unit combination pattern with high performance, and reducing the UE detection resource. The complexity of the unit combination pattern.

In an embodiment, the sequence number of the configuration may be determined by the number of ports configured by the channel state information pilot, wherein the channel state information of the channel number information having a larger number of ports has a smaller sequence number value, and the channel state information of the port number is smaller. The sequence number value of the frequency configuration is large; or the channel state information pilot configuration with a larger number of ports has a larger sequence number value, and the channel state information pilot configuration with a smaller number of port numbers has a smaller sequence number value.

The channel state information pilot resource of one port number is aggregated by using the channel state information pilot configuration, and the number of ports configured for the channel state information pilots participating in the aggregation is the same; the channel number information pilot configuration with the same number of ports is assigned consecutive numbers. The complexity of the base station can be reduced, the complexity of the terminal can be reduced, and the signaling overhead can be reduced. In the scenario where there are many new terminals, the frequency of the channel state information pilot configuration with a large number of ports is high, and the number of ports is high. The larger channel state information pilot configuration allocates a smaller sequence number, which can reduce the signaling overhead, can reduce the complexity of the base station retrieval, and can reduce the complexity of the terminal detection; the data is transmitted frequently in the traditional terminal. In the scenario, the channel state information pilot configuration with a smaller number of ports allocates a smaller sequence number, which can reduce signaling overhead, reduce the complexity of base station retrieval, and reduce the complexity of terminal detection.

In an embodiment, the offset position of the channel state information pilot configuration may be determined by the type of code division multiplexing of the channel state information pilot resources in conjunction with the number of ports of the channel state information pilot configuration.

Wherein, when the code division multiplexing length is 2, the resource unit patterns of the channel state information pilot configurations of different port numbers are different, and the channel state information pilot configuration of different port numbers in the case of code division multiplexing length 4 is The resource unit patterns are different. When the code division multiplexing length is 8, the resource unit patterns of the channel state information pilot configurations of different port numbers are different. In the case where the code division multiplexing length is 8, the scenario of the channel state information pilot configuration of different port numbers is different. For example, the channel state information pilot configuration with a large number of ports can be used in a high density case, Can be used in low-density situations; the channel state information pilot configuration with a small number of ports can only be used in low-density situations; for example, 32-port channel state information pilot resources consist of a 32-port channel state The information pilot configuration is aggregated. The offset position of the configuration in the frequency domain is 0, or 1, or 2; the channel state information of 32 ports is guided by the channel state information pilot configuration of two 16 ports. One of the configured offset positions is 0, and the other configuration has an offset position of 1. The resource unit patterns of the two configurations may be the same or different; the channel status information pilot resources of the 24 ports Aggregated by a channel state information pilot configuration of one 24 ports, the offset position of the configuration in the frequency domain is 0, or 1, or 2; the channel state information pilot resources of 24 ports are composed of 3 8 The channel state information pilot configuration aggregation of the port, wherein one configuration has an offset position of 0, another configuration has an offset position of 1, and the remaining configuration has an offset position of 2. The three configured resource unit patterns may be The same, can also be different. In the case where the code division multiplexing length is 2 or 4, the offset position of the channel state information pilot configuration of different port numbers is different from the case where the above code division multiplexing length is 8.

Determining the configured offset position by the number of ports configured by the code division multiplexing class and the channel state information pilot can save the signaling overhead of the offset location, and avoid the base station preparing various offset positions to reduce the complexity of the base station. Avoid the terminal's preparation of various offset positions to reduce the complexity of the terminal.

In an embodiment, the offset position of the channel state information pilot configuration may be jointly determined by the number of ports of the channel state information pilot resource, the type of code division multiplexing, and the number of ports configured by the channel state information pilot.

Wherein, in the case that the code division multiplexing length is 8, for example, the channel state information pilot resources of the 32 ports are aggregated by the channel state information pilot configuration of one 32 ports, and the offset position of the configuration in the frequency domain is 0, or 1, or 2; 32-port channel state information pilot resources are aggregated by two 16-port channel state information pilot configurations, one of which has an offset position of 0 and another configuration bias The resource unit pattern of the two configurations may be the same or different; the channel state information pilot resources of the 24 ports are aggregated by a channel state information pilot configuration of one 24 ports, The offset position in the frequency domain is set to 0, or 1, or 2; the channel state information of the 24 ports. The pilot resource is aggregated by the channel state information pilot configuration of three 8 ports, and the offset of one configuration is performed. The position is 0, the offset position of the other configuration is 1, and the offset position of the remaining configuration is 2. The resource unit patterns of the three configurations may be the same or different. In the case where the code division multiplexing length is 2 or 4, the offset position of the channel state information pilot configuration of different port numbers is different from the case where the above code division multiplexing length is 8.

The number of ports of the channel state information pilot resource, the type of code division multiplexing, and the number of ports configured by the channel state information pilot jointly determine the offset position of the configuration, which can save the signaling overhead of the offset location and avoid the preparation of the base station. The operation of the offset position reduces the complexity of the base station and prevents the terminal from preparing a plurality of offset positions to reduce the complexity of the terminal.

In an embodiment, the density of the channel state information pilot resources may be determined by the type of code division multiplexing of the channel state information pilot resources in conjunction with the number of ports of the channel state information pilot configuration.

The different code division multiplexing types and the number of ports configured by the channel state information pilots correspond to different channel state information pilot resource density ranges; the code division multiplexing type and the configured port number jointly determine the density of the resources, The signaling overhead of the offset location is saved, and the base station is prevented from preparing multiple density operations to reduce the complexity of the base station, and the terminal is prevented from preparing multiple density operations to reduce the complexity of the terminal.

For example, if the code division multiplexing length is 2 or 4, the resource density corresponding to the channel state information pilot configuration of all port numbers may be 1, 1/2 or 1/3. In the case where the code division multiplexing length is 8, for example, the channel state information pilot resources of 32 ports are aggregated by a channel state information pilot configuration of one 32 ports, and the density of the configuration may be 1, 1/2 or 1 /3; 32-port channel state information pilot resources can also be aggregated by two 16-port channel state information pilot configurations, the density of the configuration can be 1/2, and the resource unit patterns of the two configurations can be The same, may also be different; 24 port channel state information pilot resources are aggregated by a channel state information pilot configuration of 24 ports, the density of the configuration may be 1, 1/2 or 1/3; The channel state information pilot resources of the 24 ports are aggregated by the channel state information pilot configuration of three 8 ports. The density of the configuration may be 1/3. The resource unit patterns of the three configurations may be the same or may be the same. It is different.

In an embodiment, the density of the channel state information pilot resources may be jointly determined by the number of ports of the channel state information pilot resource, the type of code division multiplexing, and the number of ports configured by the channel state information pilot.

The number of ports of the channel state information pilot resource, the number of different code division multiplexing and the number of ports configured by the channel state information pilot correspond to different channel state information pilot resource density ranges; the number of ports of the channel state information pilot resources The type of code division multiplexing and the number of ports configured by the channel state information pilot jointly determine the density of the channel state information pilot resources, which can save the signaling overhead of the offset location, and avoid the base station preparing multiple density operations to reduce the base station. Complexity, avoiding the terminal preparing multiple density operations to reduce the complexity of the terminal.

In an embodiment, among the candidate channel state information pilot configurations of the same number of ports, there are L channel state information pilot configurations, and the L channel state information pilot configurations may have K identical codes. A resource unit pattern having a length of 8 is multiplexed, L is an integer greater than or equal to 2, and K is an integer greater than or equal to 1.

Wherein, when a part of resource element patterns of a plurality of channel state information pilot configurations overlap, a larger number of channel state information pilot configurations can be constructed, so that more high-performance channel state information pilot configuration combinations can be selected to Aggregated into channel state information pilot resources.

FIG. 9 is a flowchart of a method for parsing configuration information of a channel state information pilot resource according to the embodiment. As shown in FIG. 9, the steps of the method include:

In step 902, the terminal receives the signaling sent by the base station, where the signaling carries the configuration information of the channel state information pilot resource configured by the base station;

In step 904, the terminal parses the configuration information;

The configuration information of the channel state information pilot resource may include at least one of the following: a code division multiplexing type of the channel state information pilot resource, a port number of the channel state information pilot resource, and a density of the channel state information pilot resource. a sequence number of a channel state information pilot configuration for aggregating the channel state information pilot resource and an offset position of the channel state information pilot configured in the frequency domain.

The resource unit pattern of the channel state information pilot configuration is determined by at least a combination of a code division multiplexing type of the channel state information pilot resource and a sequence number of the channel state information pilot configuration.

In this embodiment, the channel state information pilot resources may be aggregated by the channel state information pilot configuration, may be aggregated by one channel state information pilot configuration, or may be aggregated by multiple configurations; resources of the channel state information pilot configuration The unit pattern is determined by the code division multiplexing class and the channel state information pilot configuration sequence number. That is, the same channel state information pilot configuration sequence number, the resource unit patterns of the channel state information pilot configuration corresponding to different code division multiplexing classes are independent, and may not be the same resource unit pattern. In this way, the class of code division multiplexing is used to help distinguish the resource unit patterns of the different channel state information pilot configurations, so that it is not necessary to allocate a large number of different sequence numbers for the resource unit patterns of a large number of different channel state information pilot configurations, so that the letter can be saved. Make the cost. In the case where the code division multiplexing class participates in determining the resource element pattern of the channel state information pilot configuration, the base station or terminal may reduce the retrieval complexity of the resource unit pattern for the predefined channel state information pilot configuration. For example, in the case where the code division multiplexing class is determined, the resource unit pattern of the channel state information pilot configuration corresponding to the code division multiplexing class is preloaded without loading all the predefined channel state information pilot configurations. Resource unit pattern.

In an embodiment, the resource unit pattern of the channel state information pilot configuration is combined by at least a code division multiplexing class of the channel state information pilot resource, a sequence number of the channel state information pilot configuration, and a port number of the channel state information pilot resource. determine.

The resource element patterns of the channel state information pilot resources of different port numbers are different, so that the number of pilot resource ports of the channel state information is used to help distinguish the resource unit patterns of different channel state information pilot configurations, so that it is not necessary for a large number of The resource unit patterns of different channel state information pilot configurations are allocated a large number of different sequence numbers, which can save signaling overhead. Similarly, the base station or terminal can reduce the retrieval complexity of the resource unit pattern for the predefined channel state information pilot configuration. For example, in the case where the number of channel state information pilot resource ports is determined, the resource unit pattern of the channel state information pilot configuration corresponding to the number of channel state information pilot resource ports is preloaded without loading all the predefined Resource unit pattern of channel state information pilot configuration.

In an embodiment, in the case where the code division multiplexing length is 8, the channel state information pilot resources may be aggregated by the consecutive sequence number channel state information pilot configurations.

In an embodiment, in the case that the code division multiplexing length is 8, the candidate channel state information pilot configuration includes multiple types, the number of ports of each type of the configuration is different, and the channel state information of the port number is M. The frequency resource can be configured to be aggregated by a channel state information pilot configuration of any of the candidate types, M being a positive integer.

The code division multiplexing length is 8 to aggregate the channel state information pilot resources with a relatively large number of ports, for example, to aggregate channel state information pilot resources of 24 ports, for example, to aggregate channel state information pilot resources of 32 ports. The channel state information pilot configuration with a large number of ports is used for aggregation, which can reduce the number of channel state information pilot configurations used, and bind the resource unit combination pattern with higher performance, thereby reducing signaling overhead and reducing The small base station retrieves the complexity of the resource unit combination pattern with high performance, and reduces the complexity of the UE detecting the resource unit combination pattern. For example, the 32-port channel state information pilot resources are aggregated by the 32-port channel state information pilot configuration. For example, the channel state information pilot resources of 24 ports are aggregated by the channel state information pilot configuration of 24 ports. However, in the case that the legacy terminal simultaneously transmits data, the channel state information pilot configuration aggregation with a large number of ports is adopted, and if low-density transmission is adopted, the rate matching of data transmission of the legacy terminal cannot be taken into consideration. The channel state information pilot configuration aggregation with a small number of ports can balance the rate matching of data transmission of the legacy terminal. The channel state information pilot resource with the number of ports M can be configured to be aggregated by the channel state information pilot configuration of one of the candidate types. The channel state information pilots of different candidate types are configured with different numbers of ports, which can be flexibly supported. The complexity of the system (base station and terminal) is reduced, and the rate matching of the traditional terminal can be considered when the data is transmitted by the traditional terminal.

In an embodiment, a candidate type of channel state information pilot configuration may be composed of 4 resource division patterns having a code division multiplexing length of 8.

The channel state information pilot resources of, for example, 32 ports may be aggregated by such a configuration, and the channel state information pilot resources of the 24 ports may also be aggregated by such a configuration. In this way, the number of configurations used is reduced, and the resource unit combination pattern with higher performance is bound, thereby reducing signaling overhead, reducing the complexity of the base station retrieving the resource unit combination pattern with high performance, and reducing the UE detection resource. The complexity of the unit combination pattern.

In an embodiment, a channel state information pilot configuration of the candidate type may be composed of two resource unit patterns of code division multiplexing length 8.

Wherein, for example, channel state information pilot resources of 32 ports can be aggregated by such two configurations; in particular, in the case of 1/2 density, two identical configurations are aggregated, but the offset positions of the two configurations are different, For example, 0 and 1 respectively. In such a low-density case, the number of configurations used for aggregation can be reduced to some extent, and the rate matching of the legacy terminal can be taken into consideration.

In an embodiment, a candidate type channel state information pilot configuration may be configured by three resource division patterns having a code division multiplexing length of 8;

In an embodiment, the sequence number of the channel state information pilot configuration may be determined by the number of ports configured by the channel state information pilot, wherein the channel state information pilot configuration having a larger number of ports has a smaller sequence number value and a smaller number of ports. The channel state information pilot configuration has a large sequence number value; or the channel state information pilot configuration with a larger number of ports has a larger sequence number value, and the channel state information pilot configuration with a smaller port number has a smaller sequence number value.

The channel state information pilot resource of one port number is aggregated by using the channel state information pilot configuration, and the number of ports participating in the aggregation configuration is the same; assigning consecutive sequence numbers to the configuration with the same number of ports can reduce the complexity of the base station and reduce The complexity of the terminal is reduced, and the signaling overhead is reduced. In a scenario where there are many new terminals, the configuration with a larger number of ports will have a higher frequency of use, and the configuration with a larger number of ports will assign a smaller number. The small signaling overhead can reduce the complexity of the base station retrieval and reduce the complexity of the terminal detection. In the scenario where the traditional terminal transmits data frequently, the configuration with a smaller number of ports assigns a smaller number, which can be reduced. Small signaling overhead can reduce the complexity of base station retrieval and reduce the complexity of terminal detection.

In an embodiment, the offset position of each channel state information pilot configuration may be determined by the type of code division multiplexing of the channel state information pilot resources in conjunction with the number of ports of the channel state information pilot configuration.

The resource unit pattern of the channel state information pilot configuration of different port numbers is different when the code division multiplexing length is 2, and the resource unit of the channel state information pilot configuration of different port numbers in the case where the code division multiplexing length is 4 If the patterns are different, the resource unit patterns of the channel state information pilot configurations of different port numbers are different in the case where the code division multiplexing length is 8. In the case of a code division multiplexing length of 8, the channel state information pilot configuration of different port numbers is different in use. For example, a configuration with a large number of ports can be used in both high density and low density. In this case, the configuration with a small number of ports can only be used in the case of low density; for example, the channel state information pilot resources of 32 ports can be aggregated by the channel state information pilot configuration of one 32 ports, the configuration is The offset position in the frequency domain is 0, or 1, or 2; the channel state information of 32 ports. The pilot resource can also be aggregated by the channel state information pilot configuration of two 16 ports, one of which is configured with an offset. The position is 0, and the offset position of the other configuration is 1. The resource unit patterns of the two configurations may be the same or different. The channel status information of the 24 ports may be composed of one 24 ports. The channel state information pilot configuration aggregation, the offset position of the configuration in the frequency domain is 0, or 1, or 2; the channel state information of 24 ports may also be composed of channel states of three 8 ports. Information pilot configuration aggregation, where one configuration has an offset position of 0, another configuration has an offset position of 1, and the remaining configuration has an offset position of 2. The three configured resource unit patterns can be the same, Can be different. In the case where the code division multiplexing length is 2 or 4, the offset position of the channel state information pilot configuration of different port numbers is different from the case where the above code division multiplexing length is 8.

Determining the offset position of the channel state information pilot configuration jointly by the number of ports configured by the code division multiplexing class and the channel state information pilot can save the signaling overhead of the offset location, and avoid the operation of the base station to prepare multiple offset positions to reduce The complexity of the base station prevents the terminal from preparing a variety of offset positions to reduce the complexity of the terminal.

Wherein, in the case that the code division multiplexing length is 8, for example, the channel state information pilot resources of 32 ports may be aggregated by a channel state information pilot configuration of one 32 ports, and the configuration is in the offset position of the frequency domain. 0, or 1, or 2; 32-port channel state information pilot resources can also be aggregated by two 16-port channel state information pilot configurations, one of which has an offset position of 0 and another The configured offset location is 1, and the resource unit patterns of the two configurations may be the same or different; the channel state information of the 24 ports may be guided by the channel state information of one 24 ports. Configure the aggregation. The offset position of the configuration in the frequency domain is 0, or 1, or 2; the channel state information of the 24 ports. The pilot resource can also be aggregated by the channel state information pilot configuration of three 8 ports. One of the configured offset positions is 0, the other configuration has an offset position of 1, and the remaining one has an offset position of 2. The three configured resource unit patterns may be the same or different. In the case where the code division multiplexing length is 2 or 4, the offset position of the configuration of the number of different ports is different from the case where the above code division multiplexing length is 8.

The number of ports of the channel state information pilot resource, the type of code division multiplexing, and the number of ports of the channel state information pilot configuration jointly determine the offset position of the pilot configuration of the channel state information, which can save the signaling overhead of the offset position. The operation of the base station to prepare various offset positions is avoided to reduce the complexity of the base station, and the operation of the terminal to prepare various offset positions is avoided to reduce the complexity of the terminal.

The number of ports configured by different code division multiplexing and channel state information pilots corresponds to different channel state information pilot resource density ranges; the type of code division multiplexing is combined with the number of ports configured by the channel state information pilot to determine resources. The density can save the signaling overhead of the offset location, avoid the base station preparing various density operations to reduce the complexity of the base station, and avoid the terminal preparing various density operations to reduce the complexity of the terminal.

For example, if the code division multiplexing length is 2 or 4, the resource density corresponding to the channel state information pilot configuration of all port numbers may be 1, 1/2 or 1/3. In the case where the code division multiplexing length is 8, for example, the channel state information pilot resources of 32 ports can be aggregated by the channel state information pilot configuration of one 32 ports, and the density of the resources can be 1, 1/2 or 1. /3; 32-port channel state information pilot resources can also be aggregated by two 16-port channel state information pilot configurations, the density of resources is 1/2, and the resource unit patterns of the two configurations can be the same , may also be different; 24 port channel state information pilot resources can be aggregated by a channel state information pilot configuration of 24 ports, the density of resources can be 1, 1/2 or 1/3; 24 The channel state information pilot resource of the port may also be aggregated by the channel state information pilot configuration of three eight ports, and the density is 1/3. The resource unit patterns of the three configurations may be the same or different.

In an embodiment, the density of the resource may be determined jointly by the number of ports of the channel state information pilot resource, the type of code division multiplexing, and the number of ports configured by the channel state information pilot.

Where the number of ports of the resource is different, the type of code division multiplexing is different, and the number of ports configured by the channel state information pilot is different, corresponding to different channel state information pilot resource density ranges; the number of ports of the resource, code division The type of the channel and the number of ports configured by the channel state information pilot jointly determine the density of the resource, which can save the signaling overhead of the offset location, prevent the base station from preparing multiple density operations to reduce the complexity of the base station, and avoid the terminal preparation. Density operation to reduce the complexity of the terminal.

In an embodiment, among the candidate channel state information pilot configurations of the same number of ports, there are L channel state information pilot configurations, and the L channel state information pilot configurations may have K identical code division multiplexing. A resource unit pattern of length 8, L is an integer greater than or equal to 2, and K is an integer greater than or equal to 1.

Wherein, in a case where a part of resource element patterns of a plurality of channel state information pilot configurations overlap, a larger number of channel state information pilot configurations can be constructed, so that more high-performance channel state information pilot configuration combinations can be selected. The pilot resources are aggregated into channel state information.

10 is a structural block diagram of an apparatus for analyzing configuration information of a channel state information pilot resource according to the embodiment, which is applied to a terminal side. As shown in FIG. 10, the apparatus may include: a receiving module 102, configured to receive by a base station. Signaling, where the signaling carries configuration information of a channel state information pilot resource configured by a base station; the parsing module 104 is coupled to the receiving module 102 and configured to parse the configuration information; wherein the channel state information pilot The configuration information of the resource includes at least one of the following: a channel state information pilot code division multiplexing class, a channel state information pilot resource port number, and a channel state information pilot resource density, used to aggregate into the channel state information guide. The sequence number of the channel state information pilot configuration of the frequency resource and the channel state information pilot are arranged at offset positions in the frequency domain.

The resource unit pattern of the channel state information pilot configuration is determined by at least a combination of a code division multiplexing class and a sequence number of the configuration.

In this embodiment, the channel state information pilot resources may be aggregated by the channel state information pilot configuration, may be aggregated by one channel state information pilot configuration, or may be aggregated by multiple channel state information pilot configurations; channel state information The resource unit pattern of the pilot configuration may be determined by the code division multiplexed class and the sequence number of the channel state information pilot configuration. That is, the same channel state information pilot configuration sequence number, the resource unit patterns of the channel state information pilot configuration corresponding to different code division multiplexing classes are independent, and may not be the same resource unit pattern. The use of the code division multiplexing class helps to distinguish the resource unit patterns of different channel state information pilot configurations, so that it is not necessary to allocate a large number of different sequence numbers for resource element patterns of a large number of different channel state information pilot configurations, which can save signaling. Overhead. In the case where the code division multiplexing class participates in determining the resource element pattern of the channel state information pilot configuration, the base station or terminal may reduce the retrieval complexity of the resource unit pattern for the predefined channel state information pilot configuration. For example, in the case where the code division multiplexing class is determined, the resource unit pattern of the channel state information pilot configuration corresponding to the code division multiplexing class may be preloaded without loading all the predefined channel state information pilots. The configured resource unit pattern.

In an embodiment, the resource unit pattern of the channel state information pilot configuration is determined in combination by at least a code division multiplexing class, a sequence number of the configuration, and a port number of the channel state information pilot resource.

The resource unit pattern of the channel state information pilot configuration corresponding to the channel state information pilot resource of different port numbers is different, so that the number of pilot resource resource ports of the channel state information is used to help distinguish resource element patterns of different channel state information pilot configurations. Therefore, it is not necessary to allocate a large number of different sequence numbers for resource element patterns of a large number of different channel state information pilot configurations, which can save signaling overhead. Similarly, the base station or terminal can reduce the retrieval complexity of the resource unit pattern for the predefined channel state information pilot configuration. For example, in the case where the number of channel state information pilot resource ports is determined, the resource unit pattern of the channel state information pilot configuration corresponding to the number of channel state information pilot resource ports is preloaded without loading all the predefined Resource unit pattern of channel state information pilot configuration.

The channel state information pilot resources that are not aggregated by any channel state information pilot configuration have the same performance, some combination performance is higher, some combination performance is lower, and channel state information with high combination performance is given. The pilot configuration allocates consecutive sequence numbers, and the channel state information pilot resources are aggregated by the configuration of consecutive sequence numbers, which can achieve higher performance, reduce the complexity of the base station to retrieve the high-performance configuration combination, and reduce the terminal lookup configuration. The complexity of the combination can also save signaling overhead.

In an embodiment, in the case that the code division multiplexing length is 8, the candidate channel state information pilot configuration includes multiple types, each type of the configured port number is different, and the port number is M channel state information. The pilot resources can be configured to be aggregated by a channel state information pilot configuration of one of any candidate types, M being a positive integer.

The code division multiplexing length is 8 to aggregate the channel state information pilot resources with a relatively large number of ports, for example, to aggregate channel state information pilot resources of 24 ports, for example, to aggregate channel state information pilot resources of 32 ports. The channel state information pilot configuration with a large number of ports is used for aggregation, which can reduce the number of channel state information pilot configurations used, and bind the resource unit combination pattern with higher performance, thereby reducing signaling overhead and reducing The small base station retrieves the complexity of the resource unit combination pattern with high performance, and reduces the complexity of the UE detecting the resource unit combination pattern. For example, 32 channel port state information pilot resources may be aggregated by 32 port channel state information pilot configurations. For example, the channel state information pilot resources of 24 ports can be aggregated by the channel state information pilot configuration of 24 ports. However, in the case of traditional terminal transmission data, a configuration with a large number of ports is used for aggregation, and if low-density transmission is used, the rate matching of data transmission of the legacy terminal cannot be balanced. The channel state information pilot configuration aggregation with a small number of ports can balance the rate matching of data transmission of the legacy terminal. The channel state information pilot resource with the number of ports M may be configured to be aggregated by the channel state information pilot configuration of one of the candidate types, and the number of ports configured by different candidate types is different, and the system can be flexibly supported to reduce the system ( The complexity of the base station and the terminal can also balance the rate matching of the traditional terminal when the traditional terminal transmits data.

In an embodiment, a configuration of the candidate type may be composed of two resource unit patterns of code division multiplexing length 8.

Wherein, for example, channel state information pilot resources of 32 ports can be aggregated by such two configurations; in particular, in the case of 1/2 density, two identical configurations are aggregated, but the configured offset positions are different, for example, respectively It is 0 and 1. In such a low-density case, the number of configurations used for aggregation can be reduced to some extent, and the rate matching requirement of the conventional terminal can be taken into consideration.

In an embodiment, a channel state information pilot configuration of the candidate type may be configured by three resource unit patterns of code division multiplexing length 8;

In an embodiment, the number of ports configured by the channel state information pilot determines the sequence number of the configuration, wherein the sequence number of the configuration with a larger number of ports is smaller, and the sequence number of the configuration with a smaller number of ports is larger; or the number of ports The larger configuration has a larger sequence number value, while the smaller port number has a smaller sequence number value.

The channel state information pilot resource of one port number is aggregated by using the channel state information pilot configuration, and the number of ports configured for the channel state information pilots participating in the aggregation is the same; assigning consecutive sequence numbers to the configuration with the same number of ports can reduce the base station. The complexity is reduced, the complexity of the terminal is reduced, and the signaling overhead is reduced. In a scenario where there are many new terminals, the channel state information pilot configuration with a larger number of ports has a higher frequency of use, and is a channel with a larger number of ports. The status information pilot configuration allocates a sequence number with a small value, which can reduce the signaling overhead, reduce the complexity of the base station search, and reduce the complexity of the terminal detection. In the scenario where the traditional terminal transmits data frequently, the number of ports is The smaller channel state information pilot configuration allocates a smaller sequence number, which can reduce signaling overhead, reduce the complexity of base station retrieval, and reduce the complexity of terminal detection.

In an embodiment, the offset position of each channel state information pilot configuration is determined by the type of code division multiplexing and the number of ports of the channel state information pilot configuration.

The resource unit pattern of the channel state information pilot configuration of different port numbers is different when the code division multiplexing length is 2, and the resource unit of the channel state information pilot configuration of different port numbers in the case where the code division multiplexing length is 4 The pattern is different, and the resource unit patterns of the different port numbers are different in the case where the code division multiplexing length is 8. In the case where the code division multiplexing length is 8, the scenario of different port number configuration is different. For example, the channel state information pilot configuration with a large number of ports can be used in both high density and low density. In case of case; the channel state information pilot configuration with a small number of ports can only be used in low density; for example, 32 channel channel state information pilot resources can be configured by one 32 port channel state information pilots Aggregation, the offset position of the configuration in the frequency domain is 0, or 1, or 2; the channel state information pilot resources of 32 ports can also be aggregated by the channel state information pilot configuration of two 16 ports, wherein The offset position of one configuration is 0, and the offset position of the other configuration is 1. The resource unit patterns of the two configurations may be the same or different; the channel status information of the 24 ports may be used by the pilot resources. A channel state information pilot configuration aggregation of one 24 ports, the offset position of the configuration in the frequency domain is 0, or 1, or 2; the channel state information of 24 ports may also be composed of three 8 pilot resources. The channel state information pilot configuration aggregation of each port, wherein one configuration has an offset position of 0, another configuration has an offset position of 1, and the remaining configuration has an offset position of 2, and the three configured resource unit patterns can be It is the same or it can be different. In the case where the code division multiplexing length is 2 or 4, the offset position of the configuration of the number of different ports is different from the case where the above code division multiplexing length is 8.

Determining the offset position of the channel state information pilot configuration by the combination of the code division multiplexing class and the number of ports configured by the channel state information pilot can save the signaling overhead of the offset location, and avoid the operation of the base station to prepare multiple offset positions. The complexity of the base station is reduced, and the operation of the terminal to prepare a plurality of offset positions is avoided to reduce the complexity of the terminal.

In an embodiment, the offset position of the configuration may be determined jointly by the number of ports of the channel state information pilot resource, the type of code division multiplexing, and the number of ports of the channel state information pilot configuration.

In an embodiment, the density of the resource may be determined by the combination of the type of code division multiplexing and the number of ports configured by the channel state information pilot.

For example, if the code division multiplexing length is 2 or 4, the resource density corresponding to the channel state information pilot configuration of all port numbers may be 1, 1/2 or 1/3. In the case where the code division multiplexing length is 8, for example, the channel state information pilot resources of 32 ports can be aggregated by a channel state information pilot configuration of one 32 ports, and the density can be 1, 1/2 or 1/3. The 32-port channel state information pilot resource can also be aggregated by the channel state information pilot configuration of two 16 ports, and the density can be 1/2. The resource unit patterns of the two configurations may be the same or Different; the channel state information pilot resources of 24 ports can be aggregated by a channel state information pilot configuration of 24 ports, and the density can be 1, 1/2 or 1/3; channel state information of 24 ports The pilot resource can also be aggregated by three 8-port channel state information pilot configurations, and the density is 1/3. The resource unit patterns of the three configurations may be the same or different.

The number of ports of the resource is different, the type of code division multiplexing is different, and the number of ports configured by the channel state information pilot is different, which corresponds to different channel state information pilot resource density ranges; the number of ports of the resource, code division The type of the channel and the number of ports configured by the channel state information pilot jointly determine the density of the resource, which can save the signaling overhead of the offset location, prevent the base station from preparing multiple density operations to reduce the complexity of the base station, and avoid the terminal preparation. Density operation to reduce the complexity of the terminal.

Wherein, in a case where a part of resource element patterns of a plurality of channel state information pilot configurations overlap, a larger number of channel state information pilot configurations can be constructed, so that more high-performance configuration combinations can be selected to be aggregated into channel states. Information pilot resources.

The disclosure is described below with reference to a number of embodiments.

Embodiment 1

In this embodiment, the base station determines configuration information of the channel state information pilot resource, generates signaling including configuration information of the channel state information pilot resource, and transmits signaling including configuration information of the channel state information pilot resource. The configuration information of the channel state information pilot resource may include at least one of: a channel state information pilot code division multiplexing class, a port number of the channel state information pilot resource, and a density of the channel state information pilot resource a sequence number of a channel state information pilot configuration for aggregating the channel state information pilot resource and an offset position of the channel state information pilot configured in the frequency domain. The resource unit pattern of the configuration is determined by at least a code division multiplexing category and a sequence number of the configuration.

For example, the code division multiplexing class may be divided by the length of the code division multiplexing, which may be a code division multiplexing length of 2, a code division multiplexing length of 4, or a code division multiplexing length of 8; The code division multiplexing class may also be divided by the code element mapping pattern of the code division multiplexing mapping, which may be a pattern mapped to 1 OFDM symbol, may be a pattern mapped to 2 OFDM symbols, may be mapped to The pattern on the 4 OFDM symbols may be a pattern mapped onto 6 OFDM symbols, or may be a pattern mapped onto 8 OFDM symbols.

For example, the density of the channel state information pilot resource may be represented by the average bandwidth of the pilot to the number of resource units occupied by each port on each resource block, which may be 1, may be 1/2, may be 1 /3, or other values.

For example, the channel state information pilot resource is aggregated by the channel state information pilot configuration, and the channel state information pilot is configured with a predefined sequence number, the sequence number is an integer, and the sequence number of the channel state information pilot configuration may start from 0 or may be It starts at 1 and can start with other numbers.

For example, the offset position of the channel state information pilot configuration in the frequency domain may be 0, indicating that the configuration is located on the first resource block of each group of resource blocks; the offset position may be 1, indicating that the configuration is located in each group of resource blocks. On the second resource block; the offset position can be 2, indicating that the configuration is on the third resource block of each group of resource blocks. Moreover, an offset position can be independently assigned for each channel state information pilot configuration participating in the aggregation.

Different code division multiplexing classes may have different channel state information pilot allocation resource unit patterns; for example, a configuration with a code division multiplexing length of 2 and a code division multiplexing length of 4 have the same set of configuration resource unit patterns. The code division multiplexing length 8 configuration has another set of configuration resource unit patterns; or, for example, a code division multiplexing length of 2 configuration, a code division multiplexing length of 4 configuration, and a code division multiplexing length of 8 configuration There is a set of configuration resource unit patterns. In the case of different code division multiplexing classes, the resource elements are numbered independently. For example, Table 4(a) shows the configuration number of a different code division multiplexing class, and Table 4(b) shows the configuration number of another different code division multiplexing class, as shown in Table 4(a) and Table 4. The numbering method of (b), the configuration of code division multiplexing length 2 and the configuration of code division multiplexing length 4 have the same set of resource unit patterns, having the same set of serial numbers; the configuration with code division multiplexing length of 8 has another configuration A set of resource unit patterns with another set of serial numbers. For example, Table 5 is another configuration number of a different code division multiplexing class, such as the numbering method of Table 5, and the code division multiplexing length 2 configuration has a set of independent resource unit patterns, and has a set of independent serial numbers; A configuration with a division multiplexing length of 4 has a set of independent resource unit patterns with a set of independent serial numbers; a configuration with a code division multiplexing length of 8 has a set of independent resource unit patterns with a set of independent serial numbers.

For example, the resource unit pattern of the channel state information pilot configuration may be determined at least by a combination of a code division multiplexing class and a sequence number of the configuration. For example, according to Table 4(a), the configured resource unit pattern is jointly determined by the code division multiplexing type and the serial number of the configuration; and, for example, according to Table 4(b), the configured resource unit pattern is divided by the code division multiplexing type. The serial number of the configuration and the number of configured ports are jointly determined;

Embodiment 2

The number of ports is jointly determined; or, as shown in Table 6(b), the configuration sequence number of another different code division multiplexing class, the resource element pattern of the configuration may be a code division multiplexing class, a sequence number of the configuration The number of ports of the channel state information pilot resource and the number of ports configured by the channel state information pilot are jointly determined.
