Detailed description of the invention

The following describes in detail the embodiments of the present application with reference to the drawings.

In wireless communication technology, a scheme is provided in which multipath beamforming is performed through a multi-element array antenna to improve beam gain and compensate for path loss. As shown in FIG. 1, fig. 1 is a schematic diagram of a multipath transmission according to an embodiment. In FIG. 1, multiple beams are implemented between a base station and a terminal via their respective multi-element array antennas. In order to obtain the beam gain, the optimal beam that matches the channel of the terminal must be selected according to the channel in which the terminal is located. A method for beam selection based on RSRP is used. However, due to multipath beamforming between the base station and the terminal, another beam at the same frequency may interfere with the beam to be selected, thereby affecting beam selection. Therefore, the channel information and the beam interference information must be accurately measured so as to realize an accurate beam selection according to the measurement result.

Fig. 2 is a flowchart of a channel measurement method according to an embodiment. As shown in FIG. 2, the method provided in this embodiment includes the steps described below.

In step S2010, measurement resource information is configured, wherein the measurement resource information is used to obtain channel state information and includes N pieces of channel measurement resource (CMR) information and M pieces of interference measurement resource (IMR) information, where N and M are positive integers. numbers.

The channel measurement method provided in this embodiment is applied to a base station in a wireless communication system, which is simply referred to as a "base station". The base station allocates various transmission resources to the terminal and sends various kinds of configuration information to the terminal such that the terminal determines the resource to be used for transmission and the various measurement or transmission instructions to be executed.

When multipath beamforming is implemented between a base station and a terminal through multi-element array antennas, the terminal must measure multiple beams formed in the base station and transmit the states of the measured beams to the base station such that the base station selects the beam with the maximum gain as the optimal beam. in order to establish a channel with the terminal for data transmission. The terminal measures the RSRP of the beams and returns the RSRP, i.e. the beam with the maximum received power is used as the beam used by the terminal. However, interference from another beam at the same frequency may affect beam selection.

In order to solve the previous problem, in this embodiment, the base station configures measurement resource information, where the measurement resource information is used to obtain channel state information. The measurement resource information includes N pieces of CMR information and M pieces of IMR information, where N and M are positive integers. The base station configures the measurement resource information in a message generation configuration (message generation configuration) or a message generation configuration. N pieces of CMR information are used for the terminal to measure beam channel states, and M pieces of IMR information are used for the terminal to measure beam interference.

The CMR information (CMR setting or CMR configuration) includes a CMR set and/or a CMR subset, wherein the channel measurement resource set includes at least one channel measurement resource subset, the channel measurement resource set includes at least one channel measurement resource, and the subset of channel measurement resources includes at least one channel measurement resource. Channel Measurement Resources represent channel measurement reference signal resources and include, but are not limited to, Channel State Information Reference Signal (CSI-RS) resource, Synchronization Signal Block (SSB) resource, Physical Broadcast Channel (PBCH) resource, SSB/PBCH- uplink sounding reference signals (SRS) resource and resource. The CSI-RS resource is mainly a non-zero power channel state information (NZP CSI-RS) reference signal resource. When the channel measurement resource set includes only one subset of channel measurement resources, the channel measurement resource information is a channel measurement resource set, otherwise it may be a subset of channel measurement resources.

In an embodiment of the present application, the channel measurement resources in each channel measurement resource subset have the same spatial characteristic, and/or the channel measurement resources in different channel measurement resource subsets have different spatial characteristics.

The specific method for configuring the channel measurement resource is as follows: the l-th channel measurement resource set is divided into Kl subsets of channel measurement resources according to a predetermined method such as a spatial characteristic, where Kl is a positive integer, and l=1, ..., N. The channel measurement resource subset includes at least one channel measurement resource, the channel measurement resources included in the channel measurement resource subset have the same spatial characteristic, and the channel measurement resources in different channel measurement resource subsets have different spatial characteristics. For example, one channel measurement resource subset is divided into K subsets, the i-th channel measurement resource subset includes Li channel measurement resources, the channel measurement resources in the Li-th channel measurement resource subset have the same spatial characteristic, and the channel measurement resource in Li- th channel measurement resource subset and the channel measurement resource in the Lj-th channel measurement resource subset have different spatial characteristics, where i, j=1, ..., K, and i is not equal to j. Here, each channel measurement resource set may include a different number of channel measurement resource subsets or the same number of channel measurement resource subsets, and each channel measurement resource subset may include the same number of channel measurement resources or a different number of channel measurement resources. Subsets of channel measurement resources in a channel measurement resource set may also be configured according to higher layer signaling.

The NZP CSI-RS interference measurement resource is configured with a sequence resource, i. e. the measurement reference signal such that the interference power is obtained according to the measurement reference signal in the NZP CSI-RS interference measurement resource. The CSI-IM resource is configured without a sequence resource, i. e. without a measurement reference, and the power received on the CSI-IM resource is not an interference power. Typically, parameters such as quasi-collocation are not configured. For example, the IMR information includes M interference measurement resource sets, the M interference measurement resource sets include M1 interference measurement resource subsets in total, and/or the M interference measurement resource sets include M2 interference measurement resource subsets in total. M1 and/or M2 is greater than 1. When the interference measurement resource set includes only one interference measurement resource subset, the interference measurement resource information is an interference measurement resource set, otherwise it may be a subset of interference measurement resources. If the subset of interference measurement resources is divided into sub-subsets of interference measurement resources, the interference measurement resource information is a sub-subset of interference measurement resources.

In an embodiment of the present application, the interference measurement resources in each interference measurement resource subset have the same spatial response, and/or the interference measurement resources in different interference measurement resource subsets have different spatial responses.

The subset The interference measurement resources includes at least one interference measurement resource, the interference measurement resources included in the interference measurement resource subset have the same spatial characteristic, and the interference measurement resources in different interference measurement resource subsets have different spatial characteristics. For example, the interference measurement resource set is divided into O subsets, and the i-th interference measurement resource subset includes Li IMR, the interference measurement resources in the Li-th interference measurement resource subset have the same spatial characteristic, and the interference measurement resource in the Li-th the interference measurement resource subset and the interference measurement resource in the Lj-th interference measurement resource subset have different spatial characteristics, where i, j=1, ..., K, and i is not equal to j. Here, each interference measurement resource set may include a different number of interference measurement resource subsets or the same number of interference measurement resource subsets, and the interference measurement resource subset may be divided into at least one interference measurement resource subset.

The identifiers of the interference measurement resources included in the interference measurement resource set and/or the interference measurement resource subset are uniformly or generally ordered such that the interference measurement resources included in the interference measurement resource set and/or the interference measurement resource subset have unique identifiers. , which are not repeated.

After receiving the measurement resource information, the terminal can measure the channel and interference separately according to N pieces of channel measurement resource information and M pieces of interference measurement resource information included in the measurement resource information.

The terminal receives N pieces of channel measurement resource information and M pieces of interference measurement resource information configured by the base station, obtains information on associations between the N pieces of channel measurement resource information and M pieces of interference measurement resource information, and calculates channel state information by using the N pieces of resource information of the channel measurements and the M pieces of interference measurement resource information; and an association-based relationship between the N pieces of channel measurement resource information and the M pieces of interference measurement resource information. For example, the channel state information is calculated by using the channel measurement resource in the i-th channel measurement resource subset and the interference measurement resource in the j-th interference measurement resource subset, where the i-th subset (set) of the channel measurement resources and the j-th subset (set ) interference measurement resources have an association based relationship, i=1, ..., N, j=1, ..., M, and N and M is the number of subsets (sets) of channel measurement resources and the number of subsets (sets) of resources interference measurements, respectively.

Optionally, after sending the measurement resource information, the base station can further receive channel state information sent by the terminal, the channel state information including a channel related parameter and/or an interference related parameter. When receiving the channel state information sent by the terminal, the base station can determine the channel states and interference of the beams emitted by the base station to the terminal, so that the base station can select the optimal beam to establish a communication connection with the terminal so as to realize the transmission data.

The base station receives various parameters measured and sent by the terminal, i. e. channel state information that includes a channel-related parameter and/or an interference-related parameter.

The differential IQI includes at least one of a differential IRSRP (i.e., a differential value between IRSRPi and IRSRP, or a differential of IRSRPi with respect to RSRP, the IRSRPi being obtained via the i-th piece of interference resource information) or a differential value between differential L1-SINRi and L1-SINR, wherein L1-SINRi represents the ratio of the average power of the resource corresponding to the i-th piece of channel measurement information to the average received power of the interference measurement resource corresponding to the i-th piece of interference measurement information corresponding to the i-th piece of channel measurement information, to for example, the ratio of the average received power of the CSI-RS resource in the channel measurement information (including a set of channel measurement information or a subset of channel measurement information) to the received power of the corresponding interference measurement information (wherein the received power of the interference measurement information includes the average received power of one NZP CSI-RS or the received power of one CSI-RS ZP, or the sum of the average received power of one NZP CSI-RS and the received power of one CSI-RS ZP in the interference measurement information set, or in the interference measurement information subset, or in the interference measurement information subset, and NZP CSI-RS may be replaced by an SSB resource). The channel state information includes a channel-related parameter and an interference-related parameter, wherein the channel-related parameter includes at least one of CRI, SSBRI, RSRP, or differential RSRP, and the interference-related parameter includes at least one from IMRI, IQI, or differential IQI.

In an embodiment, when the measurement resource information is configured, an association-based relationship between the N pieces of channel measurement resource information and the M pieces of interference measurement resource information may further be determined according to a predetermined rule. An association-based relationship between the N pieces of channel measurement resource information and the M pieces of interference measurement resource information may be preset in the base station or the terminal. If an association-based relationship is pre-established in the base station, the base station first sends signaling to the terminal after determining the association-based relationship, the first signaling being used to determine the association-based relationship between N pieces of channel measurement resource information and M pieces of interference measurement resource information. The association-based relationship between the N pieces of channel measurement resource information and the M pieces of interference measurement resource information may also be referred to as "association-based relationship". The association-based relationship here includes at least one of the following: the value of one parameter is obtained according to the value of another parameter; the range of values of one parameter is obtained according to the value or range of values of another parameter; some combinations of two parameter values cannot appear at the same time; parameter 2 associated with parameter 1 is configured in parameter 1 configuration information; or the relationship between the two parameters is determined by the first signaling and/or a predefined rule.

The predetermined rule is that the channel measurement resource information and the interference measurement resource information have a one-to-one association-based relationship in index order. In particular, the predefined rule includes, but is not limited to, that the i-th interference measurement resource subset has an association-based relationship with the i-th channel measurement resource subset; the i-th subset of interference measurement resources has an association-based relationship with the i-th subset of channel measurement resources; the i-th sub-subset of interference measurement resources has an association based association with the i-th channel measurement resource; or the i-th interference measurement resource set has a relationship based on association with the i-th channel measurement resource set, where i=1, ..., N, and N is the number of pieces of channel measurement resource information or interference measurement resource information.

The predetermined rule is that an association-based relationship between the channel measurement resource information and the interference measurement resource information is determined according to the spatial characteristics of the channel measurement resource information and the interference measurement resource information. Thus, the channel measurement resource information and the interference measurement resource information, which have the same spatial characteristic, have an association-based relationship.

The channel measurement resource information piece and the interference measurement resource information piece, which have an association-based relationship, may be sent or received at the same time.

Association based relationship and correspondence are equivalent concepts and are used interchangeably throughout this document.

The first signaling may be upper layer signaling and/or physical layer signaling. The upper layer signaling includes at least one of a resource information link list, a resource information link state, or a resource information bitmap mapping. The first signaling is sent by the base station or received by the terminal, the first signaling being used to determine a relationship based on an association or correspondence between the channel measurement resource information and the interference measurement resource information.

In addition, if the number N of states included in the resource information link list is less than or equal to L, the selection of one resource information link from the resource information link list can be dynamically triggered via physical layer signaling. If the number of resource information unit states included in the resource information unit list exceeds L, the L resource information unit states shall be selected via signaling in the controls at the medium access control (MAC CE) layer from the N resource information unit states, and one information resource The resource links are dynamically selected via physical layer signaling from the L information resource link states selected via the MAC CE.

The i-th row and the j-th column (or the j-th row and the i-th column) with the value of v1 bits indicate that the i-th piece of channel measurement resource information and the j-th piece of interference measurement resource information have an association, and The i-th row and the j-th column (or the j-th row and the i-th column) with the value of v0 bits indicate that the i-th piece of channel measurement resource information and the j-th piece of interference measurement resource information have no association, wherein v0 is 0, v1 is 1 or other agreed upon non-zero integers, i=1, ..., N, j=1, ..., M, and N and M are the number of channel measurement resource information pieces and the number of information pieces interference measurement resources, respectively. Here, if the first bitmap dimension is interference measurement resource information, the i-th row and j-th column should be changed to the j-th row and i-th column. Alternatively, the i-th piece of channel measurement resource information and the j-th piece of interference measurement resource information correspond to the K-th bit position (K=(i-1)*M+j or K=(j-1)*N+i) one-dimensional bitmap. The K-th bit position with a value of v1 indicates that the i-th piece of channel measurement resource information and the j-th piece of interference measurement resource information have an association, and the K-th bit position with a value of v0 indicates that the i-th piece of information channel measurement resources and the j-th fragment of interference measurement resource information have no association, and v0 is equal to 0, v1 is equal to 1 or other agreed non-zero integers, i=1, ..., N, j=1, ..., M , and N and M are the number of channel measurement resource information pieces and the number of interference measurement resource information pieces, respectively. Here, if the indices i and j start from 0, K is expressed as K=i*M+j or K=j*N+i.

For example, the CSI-RS1 quasi-co-location reference with respect to the spatial reception parameter is CSI-RS3, and the CSI-RS2 quasi-co-location reference with respect to the spatial reception parameter is CSI-RS3. Then, CSI-RS1 and CSI-RS2 satisfy the relationship based on the quasi-co-location with respect to the spatial reception parameter.

In an embodiment, the spatial characterization of the interference measurement resource information piece is determined by the spatial characterization of the channel measurement resource information piece associated with the interference measurement resource information piece. The interference measurement resource information here mainly includes at least one of an NZP CSI-RS resource, an NZP CSI-RS resource set, an NZP CSI-RS resource subset, or an NZP CSI-RS resource subset.

In an embodiment, a reference pilot signal corresponding to a spatial characteristic of a piece of interference measurement resource information is determined by a reference pilot signal corresponding to a spatial characteristic of a piece of channel measurement resource information associated with the piece of interference measurement resource information. For example, if the spatial characteristic of the piece of channel measurement resource information is A and corresponds to the reference pilot B, the spatial characteristic of the piece of interference measurement resource information associated with the piece of channel measurement resource information is also set to A and corresponds to the reference pilot B. Thus, the spatial characteristic of the piece of interference measurement resource information has the same value and corresponds to the same reference pilot with the spatial characteristic of the piece of channel measurement resource information associated with the piece of interference measurement resource information. In particular, for example, the spatial response of the channel measurement resource subset has the same spatial reception parameter with the interference measurement resource subset or with the interference measurement resource subset associated with the (corresponding) channel measurement resource subset.

In an embodiment, the channel measurement resource information includes a repetition parameter, and the interference measurement resource information includes a repetition parameter.

An interference measurement resource information repetition parameter and an interference measurement resource information repetition parameter are defined by any of the following methods: an interference measurement resource set repetition parameter is determined by a channel measurement resource set repetition parameter associated with the interference measurement resource set; an interference measurement resource subset repetition parameter is determined by a channel measurement resource subset repetition parameter associated with the interference measurement resource subset; an interference measurement resource subset repetition parameter is determined by a channel measurement resource subset repetition parameter associated with the interference measurement resource subset; an interference measurement resource set repetition parameter and a channel measurement resource set repetition parameter associated with the interference measurement resource set are determined by an independent upper layer parameter; an interference measurement resource subset repetition parameter and a channel measurement resource subset repetition parameter associated with the interference measurement resource subset are determined by an independent upper layer parameter; or the repetition parameter of the sub-subset of interference measurement resources and the repetition parameter of the sub-set of channel measurement resources associated with the sub-subset of interference measurement resources are determined by an independent upper layer parameter.

For example, if the channel measurement resource information piece repetition parameter is enabled, the interference measurement resource information piece repetition parameter associated with the channel measurement resource information piece is enabled. For example, the repetition parameter values of the interference measurement resource subset and/or the interference measurement resource subset are determined according to the repetition parameter value of the channel measurement resource subset; or the repetition parameter values of the interference measurement resource subset and/or the interference measurement resource subset are determined according to the value of the channel measurement resource repetition parameter.

Since the base station does not know the total number of bits of channel state information to be transmitted by the terminal when sending the measurement resource information to the terminal, the base station cannot accurately schedule the uplink resource. In addition, when transmitting the channel state information, the terminal further needs to transmit the channel-related parameter and the interference-related parameter, as well as the channel state information (CSI)-related parameters other than the channel-related parameter and the interference-related parameter, and the hybrid parameter. automatic retransmission request (HARQ). A CSI other than a channel-related parameter and an interference-related parameter (with CSI parameters other than a channel-related parameter and an interference-related parameter collectively referred to as "channel quality-related parameters" herein) includes, but not only at least one of CQI, precoding matrix indicator (PMI), CRI, level indicator (LI), or rank indicator (RI). After the terminal completes the acquisition of the channel state information, a part of the channel state information must be discarded when all of the channel state information cannot be transmitted on the uplink resource.

Thereafter, the priorities of the channel state information must be ordered, with the priorities of the CSI-related parameters including at least one of the following, described below.

IQI priority is not higher than RSRP priority.

IMRI priority is not higher than CRI priority or SSBRI priority.

The IMRI priority is not lower than the RI priority.

The IMRI priority is not lower than the PMI priority.

The IMRI priority is not lower than the LI priority.

The IMRI priority is not lower than the CQI priority.

IMRI priority is higher than IQI priority and/or differential IQI priority.

The IMRI priority is higher than the RSRP priority and/or the differential RSRP priority.

IQI priority and/or differential IQI priority is higher than RI priority and/or LI priority.

The IQI priority and/or differential IQI priority is higher than the PMI priority and/or CQI priority.

The terminal encodes CSI-related parameters according to previous priorities, and may discard parameters with low priorities when the coding rate cannot reach the system requirement until the coding rate reaches the system requirement. The base station decodes the CSI related parameters according to the previous priorities. The step in which the channel state information sent by the terminal is received includes at least one of the cases described below.

CRI is accepted if IMRI is determined by CRI.

SSBRI is accepted if IMRI is determined by SSBRI.

At least one CRI, at least one RSRP and/or at least one differential RSRP are received.

At least one CRI, at least one IQI and/or at least one differential IQI are received.

At least one IMRI, at least one IQI and/or at least one differential IQI are received.

At least one IMRI, at least one RSRP and/or at least one differential RSRP and at least one IQI and/or at least one differential IQI are received.

At least one CRI, at least one IMRI, at least one RSRP and/or at least one differential RSRP are received.

At least one CRI, at least one IMRI, at least one IQI and/or at least one differential IQI are received.

At least one CRI, at least one IMRI, at least one RSRP and/or at least one differential RSRP, and at least one IQI and/or at least one differential IQI are received.

In an embodiment, the step at which the channel state information sent by the terminal is received may include that the channel state information transmitted by the terminal via the uplink resource is received. The channel-related parameter and the interference-related parameter in the channel state information must be encoded by some coding method so that the base station can realize decoding by the decoding method appropriate for the terminal. The uplink resource includes an uplink physical channel and upper layer signaling. The physical uplink channel includes at least one of a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), or a physical random access channel (PRACH). Upper layer signaling includes radio resource control (RRC) signaling and MAC CE signaling. The uplink resources here may be used to convey channel state information.

In order to simplify the description of how to convey the channel state information in a message, the channel state information must first be encoded. The number of bits of each variable in the channel state information must be determined before encoding. The number of parameter bits, such as CRI, SSBRI, or RSRP, is defined in current standards, as shown in Table 1.

After recognizing the channel state information transmission bits and their priorities, the channel state information may be encoded, and the encoded channel state information may be transmitted in an uplink resource to the base station.

The specific method for encoding the channel state information may be performed in the three methods described below.

(1) The channel-related parameter and the interference-related parameter in the channel state information are jointly encoded in one coding block.

In this case, the uplink resource is PUCCH, and both the channel-related parameter and the interference-related parameter in the channel state information are jointly encoded. The specific coding method is shown in Table 6.

Tab. 6 CSI message number CSI fields CSI message #n CRI or SSBRI or IMIR #2 as shown in tables 1 to 4 if reported CRI or SSBRI or IMIR #2 as shown in tables 1 to 4 if reported CRI or SSBRI or IMIR #3 as shown in tables 1 to 4 if reported CRI or SSBRI or IMIR #4 as shown in tables 1 to 4 if reported RSRP #1 as shown in Table 1 or 4 if reported IQI #1 as shown in Tables 2-4 if reported Differential RSRP #2 as shown in Table 1 or 4 if reported Differential RSRP #3 as shown in Table 1 or 4 if reported Differential RSRP #4 as shown in Table 1 or 4 if reported Differential IQI #1 as shown in Tables 2-4 if reported Differential IQI #2 as shown in Tables 2-4 if reported Differential IQI #3 as shown in Tables 2-4 if reported

(2) The channel-related parameter and the interference-related parameter in the channel state information are independently encoded in two coding blocks.

In this case, the uplink resource is PUCCH, and both the channel-related parameter and the interference parameter in the channel state information are independently encoded as shown in Tables 7 and 8. The coding method of the channel-related parameter is shown in Table 7. The coding method for the interference parameter is shown in Table 8.

Tab. 7 CSI message number CSI fields CSI message #n CRI or SSBRI #1 as shown in Table 1 or 4 if reported CRI or SSBRI #2 as shown in Table 1 or 4 if reported CRI or SSBRI #3 as shown in Table 1 or 4 if reported CRI or SSBRI #4 as shown in Table 1 or 4 if reported RSRP #1 as shown in Table 1 or 4 if reported Differential RSRP #2 as shown in Table 1 or 4 if reported Differential RSRP #3 as shown in Table 1 or 4 if reported Differential RSRP #4 as shown in Table 1 or 4 if reported Tab. eight CSI message number CSI fields CSI message #n IMIR #1 as shown in Table 3 or 4 if reported IMIR #2 as shown in Table 3 or 4 if reported IMIR #3 as shown in Table 3 or 4 if reported IMIR #4 as shown in Table 3 or 4 if reported IQI #1 as shown in Tables 2-4 if reported Differential IQI #1 as shown in Tables 2-4 if reported Differential IQI #2 as shown in Tables 2-4 if reported Differential IQI #3 as shown in Tables 2-4 if reported

(3) In case the channel state information includes RSRP and IQI, RSRP is encoded in the first part of coding blocks, and IQI is encoded in the wideband or subband part of the second part of coding blocks. In case the channel state information includes differential RSRP and IQI, differential RSRP is encoded in the first part of coding blocks, and IQI is encoded in the wideband or subband part of the second part of coding blocks. In case the channel state information includes RSRP and differential IQI, RSRP is encoded in the first part of the coding blocks, and the differential IQI is encoded in the wideband or subband part of the second part of the coding blocks. In case the channel state information includes a differential RSRP and a differential IQI, the differential RSRP is encoded in the first part of the coding blocks, and the differential IQI is encoded in the wideband or subband part of the second part of the coding blocks. In case the channel state information includes IQI and does not include RSRP and/or differential RSRP, the IQI is encoded in the first part of the coding blocks. In case the channel state information includes a differential IQI and does not include RSRP and/or differential RSRP, the differential IQI is encoded in the first part of the coding blocks. The transmission priority of the first part of the coding blocks is higher than the transmission priority of the second part of the coding blocks. Thus, after the terminal completes encoding, the information encoded in the first part of the encoding blocks is preferably transmitted.

At least one of CRI, SSBRI or IMIR is encoded in the first part of coding blocks as shown in Table 9 and at least one of IQI, RSRP, differential IQI or differential RSRP is encoded in the second part of coding blocks as shown in Table 10 .

Other CSI parameters in the second portion of the coding blocks, eg, at least one of subband CQI, PMI, and the like.

It should be noted that if only one of the IQI or RSRP exists, the IQI or RSRP may be encoded in only the first part of the coding blocks. The terminal encodes channel state information in the manners shown in Tables 6-10. If other CSI parameters exist, the terminal may also encode other CSI parameters, perform operations such as modulation and resource mapping on the coded data, and transmit the coded data on the PUCCH to the base station. The base station receives channel state information on the PUCCH and acquires beamforming-related parameters through a series of operations such as demodulation and decoding.

In addition, if the channel state information is transmitted on the PUSCH, other coding methods may be provided in addition to the methods in Tables 6-10, such as the coding methods shown in Tables 11-13. In Table 11, all channel state information is encoded in the first part of the coding blocks in the CSI message. In Table 12, at least one of CRI, SSBRI, IMRI, RSRP, or differential RSRP is encoded in the first part of the coding blocks in the CSI message. Table 13 shows that at least one of the IQI or the differential IQI is encoded in the wideband part of the second part of the coding blocks in the CSI message.

Thus, transmission on the PUSCH includes one of the characteristics described below.

Both the channel-related parameter and the interference-related parameter are jointly encoded in the first part of the coding blocks in the CSI message. Alternatively, at least one of the CRI, SSBRI, IMR, RSRP, or differential RSRP is encoded in the first part of the coding blocks in the CSI message, and at least one of the IQI or differential IQI is encoded in the wideband part of the first part of the coding blocks in the CSI message, or in the sub-band portion of the first portion of the coding blocks in the CSI message.

The terminal encodes channel state information in the manners shown in Tables 6-13. If other CSI parameters exist, the terminal may also encode other CSI parameters, perform operations such as modulation and resource mapping on the coded data, and transmit the coded data on the PUSCH to the base station. The base station receives channel state information on the PUSCH and acquires beamforming-related parameters through a series of operations such as demodulation and decoding.

It should be noted that the terminal may encode the channel state information in the manners in Tables 6-13 and transmit part of the channel state information on the PUCCH and another part of the channel state information on the PUSCH or upper layer signaling.

It should be noted that Tables 6-13 show only some embodiments of channel state information encoding, and other encoding methods may be provided in which channel state information is combined or split arbitrarily, which are not listed exhaustively.

Fig. 4 is a flowchart of another channel measurement method according to an embodiment. As shown in FIG. 4, the method provided in this embodiment includes the steps described below.

In step S4010, measurement resource information is received, the measurement resource information including N pieces of channel measurement resource information and M pieces of interference measurement resource information, where N and M are positive integers.

The channel measurement method provided in this embodiment is applied to a terminal device in a wireless communication system, which is simply referred to as a "terminal". The terminal completes data transmission according to a transmission resource allocated by the base station, receives various kinds of configuration information sent by the base station, determines a resource required for transmission according to various kinds of configuration information, and executes measurement instructions indicated by various kinds of configuration information.

When multipath beamforming is implemented between a base station and a terminal through multi-element array antennas, the terminal must measure multiple beams formed in the base station and transmit the states of the measured beams to the base station such that the base station selects the beam with the maximum gain as the optimal beam. in order to establish a channel with the terminal for data transmission. The terminal measures the RSRP of the beams and transmits the RSRP, i. e. the beam with the maximum received power is used as the beam used by the terminal. However, interference from another beam on the same frequency may affect beam selection.

In order to solve the previous problem, in this embodiment, the terminal receives measurement resource information sent by the base station, where the measurement resource information includes N pieces of channel measurement resource information and M pieces of interference measurement resource information, where N and M are positive integers. .

The specific meaning of the measurement resource information and the specific meanings and relationships between the N pieces of channel measurement resource information and the M pieces of interference measurement resource information in the measurement resource information are described in detail in the embodiment shown in FIG. 2, which are not repeated here.

In step S4020, channel state information is acquired according to measurement resource information, wherein the channel state information includes a channel-related parameter and/or an interference-related parameter.

After receiving the measurement resource information, the terminal can measure the channel and the interference separately according to the N pieces of channel measurement resource information and the M pieces of interference measurement resource information included in the measurement resource information to obtain channel state information, the channel state information including a channel associated parameter and/or interference-related parameter.

The meaning of the channel state information and the relationship between the channel-related parameter and the interference-related parameter is described in detail in the embodiment shown in FIG. 2, which is not repeated here.

In step S4030, the channel state information is transmitted to the base station.

After receiving the channel state information, the terminal transmits the channel state information to the base station. The base station receives various parameters measured and sent by the terminal, i. e. channel state information that includes a channel-related parameter and/or an interference-related parameter. The channel-related parameter is a parameter measured by the terminal in response to the channel measurement resource, and the interference-related parameter is a parameter measured by the terminal in response to the interference measurement resource. When receiving the channel state information sent by the terminal, the base station can determine the channel states and interference of the beams emitted by the base station to the terminal, so that the base station can select the optimal beam to establish a communication connection with the terminal so as to realize the transmission data.

For the embodiment shown in FIG. 4, compositions and relationship between a channel measurement resource and an interference measurement resource, compositions and a relationship between a channel-related parameter and an interference-related parameter, how a base station transmits channel state information to a base station, and a specific method for how to encode the information. channel states are described in detail in previous embodiments and are not repeated here.

Note that the embodiments of the present application will only be described using an example in which a base station configures measurement resource information, sends measurement resource information to a terminal, and receives channel state information sent by the terminal, i. the channel state information is transmitted via the uplink resource. However, in fact, the terminal also supports beamforming such that, for the base station and the terminal, the channel state information can also be transmitted via the downlink resource, i.e. the base station transmits the channel state information to the terminal such that the terminal selects the corresponding uplink beam. The specific methods are similar to those provided in the embodiments of the present application, except that the uplink resource is replaced with a downlink resource. Those skilled in the art can implement the transmission of channel state information over the downlink resource according to the channel measurement methods provided by the present application, which is not repeated in this embodiment.

In addition, when the same receiving end receives signals on the same symbol by using the same received beam, the channels or the signal cannot be flexibly received according to the channel characteristics corresponding to different transmit-receive points (TRPs) in the case of joint transmission over multiple TRPs. Therefore, an embodiment of the present application further provides a method for determining a spatial reception parameter.

A method for determining a spatial reception parameter in an embodiment of the present application includes the steps described below.

Pieces of group information associated with A types of channels and/or signals are defined.

At least one of the following is determined according to certain pieces of group information associated with A types of channels and/or signals: a spatial reception parameter of at least one type of channel and/or signal from A types of channels and/or signals or a transmission method of A types channels and/or signals.

The intersection between time domain resources occupied by A types of channels and/or signals is non-empty, and A is a positive integer greater than or equal to 2.

In an embodiment of the present application, the pieces of group information associated with the A types of channels and/or signals are determined, and the spatial reception parameter of at least one type of channel and/or signal from the A types of channels and/or signals is determined according to the pieces of information of the groups, associated with A types of channels and/or signals.

The stage at which the spatial reception parameter of at least one type of channel and/or signal from A types of channels and/or signals is determined according to certain pieces of group information associated with A types of channels and/or signals, includes at least one of steps described below.

In case the pieces of information of the groups associated with the A types of channels and/or signals are the same, the A types of channels and/or signals satisfy the relationship based on quasi-joint placement with respect to the spatial reception parameter.

In case the pieces of information of the groups associated with the A types of channels and/or signals are the same, the A types of channels and/or signals satisfy the relationship based on quasi-joint placement with respect to the spatial reception parameter at the intersection.

In case the pieces of group information associated with the A types of channels and/or signals are different, each type of channel and/or signal of the A types of channels and/or signals is associated with a spatial reception parameter.

In case the pieces of group information associated with the A types of channels and/or signals are different, each type of channel and/or signal of the A types of channels and/or signals is associated with a spatial reception parameter at the intersection.

In the description below, with A=2 as an example, the following relationship is satisfied when the pieces of group information associated with A types of channels and/or signals are the same. If the pieces of group information associated with the A types of channels and/or signals are different, the following relationship need not necessarily be satisfied.

Case one: When the interval between the downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH) and the PDSCH is less than a predetermined threshold, the time domain intersection between the PDSCH and the control resource set (core set) is non-empty (and the base set is configured to be blocks of time-frequency resources for transmitting downlink control information), the PDSCH and the base set have different "OCL types D" (i.e., spatial reception parameters), and the PDSCH and the base set are associated with the same piece of group information, a physical downlink control channel (PDCCH) in the core set is preferably received. In this case, the "QCL Type D" of the PDSCH is the "QCL Type D" of a core set that is associated with at least one search space to be discovered and has a minimum CORESETID in the unit of time closest to the PDSCH, and resides in the Carrier Component (CC) on which the PDSCH is located.

Case two: If the CSI-RS resource configured for the UE and the base set associated with the search space set has at least one same orthogonal frequency division multiplexing (OFDM) symbol, and the CSI-RS and the base set have the same group identifier, the terminal assumes that the CSI-RS and demodulation reference signals (DMRS) of all PDCCHs included in the core set associated with the search space set satisfy the quasi-collocation based relationship with respect to "QCL-type D" if "QCL- type D" is configured. This is also applicable to the case in which the CSI-RS and the core set are in different in-band component carriers.

Case three: If the intersection between the time domain OFDM symbols occupied by the SS/PBCH resource block and the CSI-RS resource configured by the terminal is non-empty, and the CSI-RS resource and the SS/PBCH resource block have the same the group identifier, the CSI-RS, and the SS/PBCH resource block satisfy the relationship based on the quasi-collocation with respect to the "QCL-type D" if the "QCL-type D" is applied.

Case four: If the intersection between the OFDM symbols occupied by the SS/PBCH resource block and the DMRS PDSCH received by the terminal is non-empty, and the DMRS PDSCH and the SS/PBCH resource block have the same group ID, the DMRS and the SS/ The PBCH resources satisfy the relationship based on the quasi-collocation with respect to the "QCL type D" if the "QCL type D" is configured.

Case five: If the terminal is configured in single carrier mode or carrier aggregation (CA) mode, the intersection between detection periods of PDCCHs belonging to multiple base sets is non-empty, and these base sets have the same group ID, the terminal detects one of the multiple base sets, and PDCCH in a base set that satisfies QCL type D with one of the base sets.

The group identifier is at least one of a downlink control channel element group index, a TCI state group index, an antenna group index, a channel and/or signal group index, or a channel and/or signal parameter value group index. The downlink control channel element includes one of a base set, a search space set, a search space, or a PDCCH candidate. For example, different groups correspond to different TRPs.

When the intersection between the A channel and/or signal types is non-empty and the A channel and/or signal types have the same group index, the A channel and/or signal types satisfy the quasi-collocation based relationship with respect to the QCL-type D (i.e., parameter spatial reception). In this embodiment, it is not ruled out that when the intersection between the A channel and/or signal types is non-empty and the A channel and/or signal types have the same group index, the number of reference signals included in the set consisting of the quasi-collocation reference signals A types of channels and/or signals relative to the QCL-type D (i.e., the parameter of spatial reception), less than the third predetermined threshold, or the number of reference signals that do not satisfy the relationship based on quasi-collocation and are included in the set consisting of reference signals quasi-co-location A types of channels and/or signals relative to the QCL-type D (ie, the spatial reception parameter) is less than a third predetermined threshold value. For example, a terminal may emit more than one received beam for one TRP.

When the intersection between the A channel and/or signal types is non-empty and the A channel and/or signal types have different group indices, the A channel and/or signal types need not satisfy a quasi-collocation based relationship with respect to the QCL-type D (i.e. . spatial reception parameter), and the number of reference signals that do not satisfy the relationship based on quasi-collocation, and are included in the set consisting of quasi-collocation reference signals A of channel types and/or signals relative to the QCL type D (i.e., the spatial parameter reception) is less than a fourth predetermined threshold, wherein the fourth threshold is greater than the third predetermined threshold. For example, the terminal may emit a predetermined number of received beams for each TRP, and the number of received beams that can be emitted by the terminal for two TRPs exceeds the number of received beams that can be emitted by the terminal for one TRP.

In an embodiment, one channel and/or signal is associated with one downlink control channel element group, which includes at least one of the cases described below.

A physical layer control channel for channel and/or signal scheduling is transmitted in a downlink control channel element group.

Upper layer signaling for channel and/or signal scheduling is included in a downlink data channel scheduled by a control channel transmitted in a downlink control channel element group. For example, if an RRC/MAC CE command for scheduling periodic or semi-persistent channels and/or signals is included in the PDCCH of base set group 1, the base set group associated with these periodic or semi-persistent channels and/or signals is referred to as "base set group 1" .

In the embodiment, in the previous cases one to five, in case the pieces of information of the groups associated with the A types of channels and/or signals are different, the A types of channels and/or signals do not have to satisfy the relationship based on quasi-joint placement with respect to the spatial reception parameter.
