Description
Technical Field
The present invention relates to the field of wireless communications, and in particular, to a method, an apparatus, a device, a base station, and a terminal for processing information.
Background
In a wireless communication system, a transmitting end and a receiving end generally adopt a plurality of antennas to transmit and receive to obtain higher rate; one principle of the multi-antenna technology is that a plurality of characteristics of channels are utilized to form multi-layer transmission matched with the characteristics of the channels, the radiation direction of signals is very targeted, the system performance can be effectively improved, and remarkable performance improvement can be obtained on the basis of not increasing the bandwidth and the power.
When multi-antenna transmission is performed, the radiation directions of signals are generally more excellent and concentrated through precoding, and with the increasing number of antennas, the pure baseband precoding may bring huge cost, so that the mixed use of radio frequency precoding and data precoding technology is a future trend; fig. 1 is a block diagram of a multi-day transceiver system using mixed baseband and rf precoding, and the mathematical model of the system can be expressed as follows, as shown in fig. 1:
y=WBBWRFHFRFFBB+n
for the above mathematical model formula, wherein:
y is a received wireless signal, and the dimensionality is the number Nr of the receiving units RXU;
n is interference and noise, and the dimensionality is also the number Nr of the receiving units RXU;
h is a channel;
WBBthe dimension of the baseband receiving weight of the receiving end is related to the number Nr of the receiving units RXU and the layer number of data;
WRFthe dimensionality of the radio frequency receiving weight of a receiving end is related to the number Nr of receiving units RXU and the number of antenna elements in a receiving antenna group;
FBBthe dimension of the base band precoding weight of the sending end is related to the number Nt of the sending units TXU and the number of data layers;
FRFthe dimensionality of the radio frequency precoding weight of the sending end is related to the number Nt of receiving units TXU and the number of antenna elements in a sending antenna group;
WBBWRFFBBFRFare all precoding weights, also known as beamforming (beamforming) weights; precoding techniques are also known as beamforming techniques; in a Multiple-Input Multiple-Output (MIMO) system using precoding, rf precoding adjusts a phase weight of a signal in a time domain, and thus acts on all subcarriers on a whole Orthogonal Frequency Division Multiplexing (OFDM) symbol, and baseband precoding adjusts a phase weight in a Frequency domain, and different baseband precoding can be used in different Frequency domain positions, so that different flexibility is provided, but generally, the cost of rf precoding is lower because only a few rf channels are needed, baseband precoding requires more rf channels, and baseband operation is more complicated; the actual system comprises a baseband pre-coding system, a radio frequency pre-coding system and a baseband radio frequency mixed pre-coding system, and the mathematical model can fix WRFFRFI.e. can be degraded to the baseband precoding system model if F is fixedBBOr FBBDimension 1 can be degraded to the rf precoding system model.
In MIMO systems, an important goal is to pursue obtaining accurate WBBWRFFBBFRFTherefore, the base station can effectively utilize the channel information through the transmission beamforming and the terminal through the reception beamforming to enable the signal to have a same-direction superposition effect after passing through the channels of the transmitting end and the receiving end, which is equivalent to concentrating the energy in a certain direction (which can be understood as a certain direction in a high-dimensional space corresponding to a high-dimensional channel, and is generally a direction of a feature vector in the feature space), so that a better transmit beamforming forming effect can be obtained, and the more antennas, the narrower the beam and the better the effect.
In the above mathematical model, WBBCan always be determined very flexibly and accurately according to the received information, and it is difficult to obtain WRF,FBB,FRFThe information of (a); specifically, the receiving end receives the RF weight WRFThe method needs to be predetermined before receiving, so that the receiving weight is difficult to be dynamically determined according to the received signal, and pre-training is needed; base band and radio frequency precoding weight F of sending endBB,FRFAnd the beamforming is required to be obtained by training in advance, so that the beamforming for accurately matching the channel characteristics of the terminal cannot be performed under the condition that the base station does not have any preset information.
The challenge of beamforming technology in MIMO systems is that it is very important to select a correct narrow beam, and if the selected beam does not match with the actual channel feature vector, the situation that only few or no useful signals can be received occurs, and the performance of multi-antenna beamforming is greatly reduced, so how to feed back accurate beam information is an important problem; in some current technical solutions, beam training and feedback are mainly performed in the following manners, which may be applied to downlink (where a base station sends a signal to a terminal) or uplink (where a terminal sends a signal to a base station), where the following beam training is mainly used as an example:
configuring the transmission parameters of the channel measurement beam pilot frequency to a receiving end; a sending end sends N wave beam pilot frequencies used for channel measurement; the receiving end receives the measurement beam pilot frequency configuration parameters and receives the measurement beam pilot frequencies; measuring through the N wave beam pilot frequencies to obtain channel quality information; the receiving end selects the beam pilot frequency and feeds back the corresponding beam index and quality information; it can be seen that, in the prior art, the sending end obtains the best beam direction information by sending some dedicated measurement beam pilots and corresponding measurement feedback, and the method needs more measurement beam pilot overhead; the measurement beam pilots have various embodiments and can be sent at different positions, and have different names and names, but generally, the prior art needs special pilots for beam selection and tracking.
In practical application, several factors affecting the accuracy of the beam direction can be met, wherein the problems include the Blocking (Blocking) of a main transmission path and the like, and the situation that the optimal beam direction is changed and the beam cannot be aligned or blocked due to the movement problem of the terminal; at this time, WRF,FBB,FRFThe weight obtained during the beam training is different from the real directional characteristic of the channel during the actual transmission (the left characteristic vector and the right characteristic vector of the channel are not matched with the pre-coding weight), the same-direction combination effect cannot be obtained, and when the number of antennas is large, a large amount of random phase combination can occur to cause very low received signals, so that the receiving signal-to-noise ratio of the terminal is very low, and the transmission efficiency is low; therefore, the main problem of the current system is channel path blockage or inaccurate mobile/rotating beam of the terminal, thereby causing link quality degradation.

For the selection of beams, there are two strategies, one is that if it is considered that only the blocking situation occurs, N pilots that have been trained before can be in the allocated scheduling resources to be transmitted in turn on the beams in M different directions; if it is considered that only the direction is changed to some extent due to movement or rotation, a beam, for example, a beam of 50 degrees, may be selected to transmit around the beam, for example, in the directions of 40 degrees, 60 degrees, etc., respectively, so as to obtain a good diversity effect and significantly improve robustness; the plurality of beams mentioned herein may correspond to a plurality of layers in a spatial domain, a plurality of antennas, a plurality of ports, a plurality of sectors, etc., and may correspond to a plurality of Transmission Time Intervals (TTIs), a plurality of subframes, a plurality of slots (slots), a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbol groups in a Time domain; it should be noted that, when M is large enough, there may be transmission in both adjacent beam directions and transmission in non-adjacent beam directions.
The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Fig. 4 is a flowchart of a first embodiment of a method for processing information according to the present invention, which is illustrated from the perspective of sending information from a base station to a terminal in a downlink manner in the embodiment of the present invention; as shown in fig. 4, the information processing method provided in the embodiment of the present invention includes the following steps:
The base station firstly encodes the information to be transmitted; the type of the information to be sent is data information or control information.
Specifically, the base station encodes the information to be transmitted by adopting a channel coding method according to a coding code rate; the coding rate determines the redundancy of information, and the value and/or the value range of the coding rate are determined according to the value and/or the value range of the M; the channel coding method comprises a plurality of simple channel coding methods such as a repeated coding method, a turbo coding method, an LDPC coding method and a convolution coding method.
For example, when M is equal to 2, the coding rate is required to be 1/2, or the range of coding rates is a possible coding rate less than or equal to 1/2; when M is equal to 3, the coding rate is required to be 2/M or the range of the coding rate is the possible coding rate less than or equal to 2/M; it can be summarized that the coding rate is less than or equal to f (M), where f (M) is a function with a domain of M, and preferably, f (M) is equal to 1/M.
In addition, the encoding method is determined according to the value and/or the value range of the M; for example, when M is equal to 1, the channel coding method is a Turbo coding method or an LDPC coding method; when the M is larger than 1, the channel coding method is a repetition coding method of M times.
Secondly, the base station divides the coded code block information into M sub code blocks to be sent.
Specifically, the base station divides the coded code block information into M sub code blocks to be sent; preferably, the division of the sub-code blocks needs to ensure that each sub-code block has some information after coding to indicate the same information before coding; in addition, there are various dividing ways, preferably, each sub-code block is encoded according to the same bit before encoding, but there is a special case that the contents transmitted by the sub-code blocks are the same; more practically, each encoded sub-code block has different content, but all the encoded sub-code blocks belong to the sub-code blocks representing the same information, and preferably, M sub-code blocks may include part or all of the same information to be transmitted, and the content of the M sub-code blocks may also be the same; the coding methods may be the same or different or may not be coded here (understood as a special coding method, i.e. direct mapping).
Fig. 5 is a schematic diagram of the content contained in the sub information block according to the first embodiment of the information processing method of the present invention, and as shown in fig. 5, the base station determines M sub information blocks, where the sub information blocks contain the sub code blocks and demodulation pilot resources associated with the sub code blocks.
Specifically, each sub-code block uses a group of demodulation pilot frequency resources for transmission, the demodulation pilot frequency resources used by each sub-code block may be the same or different, and the demodulation pilot frequency resources include space domain resources and/or time domain resources; the time domain resources include: at least one of a subframe, a slot, and a time domain symbol; the spatial domain resources include: at least one of antenna port, layer, sector, beam; for example, a set of demodulation pilot resources may include one or more antenna ports in the spatial domain and one or more time domain symbols in the time domain.
Fig. 6a is a schematic diagram of a first division manner of a demodulation pilot frequency resource group according to a first embodiment of the information processing method of the present invention, fig. 6b is a schematic diagram of a second division manner of a demodulation pilot frequency resource group according to a first embodiment of the information processing method of the present invention, and fig. 6c is a schematic diagram of a third division manner of a demodulation pilot frequency resource group according to a first embodiment of the information processing method of the present invention, as shown in fig. 6a, fig. 6b, and fig. 6c, a demodulation pilot frequency group can be divided in a time domain or a space domain; corresponding to the demodulation pilot group, the M sub-code blocks may be transmitted in a time division multiplexing manner or in a space division multiplexing manner.
After step 402, to improve flexibility, the base station may further send to the terminal indication information of the configured demodulation pilot resources associated with the sub-code block.
And 403, mapping the M sub-information blocks to M time domain resource groups and/or space domain resource groups after modulation, and sending the M sub-information blocks.
And the base station modulates the M sub-information blocks and then maps the M sub-information blocks to M time domain resource groups and/or space domain resource groups for sending.
The base station can determine resources contained in the time domain resource group and/or the space domain resource group according to the value and/or the value range of the M; for example, the total resources are configured or agreed, and the total resources are divided into M groups according to the value and/or value range of M and a pre-agreed method, and the M groups respectively correspond to M sub-code blocks, and transmission resources used by each sub-code block may be the same or different.
In one case, the content contained in the sub-code blocks is the same, the demodulation pilot resources used by the sub-code blocks are different, and the transmission resources used by the sub-code blocks are the same.
After step 403, if the transmission resources are to be flexibly adjusted, the base station may send, to the terminal, indication information of the configured M time-domain resource groups and/or space-domain resource groups; therefore, the terminal can accurately know which resources belong to the same group and which resources belong to different groups at which positions to perform channel detection.
And the base station informs the terminal of the value and/or the value range of the M, wherein the M is an integer which is more than or equal to 1.
Specifically, when the information to be sent is the data information, the base station notifies the terminal of the value and/or the value range of the M in a physical control channel; when the information to be sent is the control information, the base station notifies the terminal of the value and/or the value range of the M through any one of a high-level signaling or a broadcast channel and a common control channel, or the base station notifies the terminal of the value and/or the value range of the M through a physical control channel before the control information is sent.
Regarding the value and/or value range of M, the base station may determine in the following manner.
The value and/or value range of the M is determined according to a transmission mode; different values of M may be available in different transmission modes, because different transmission modes correspond to different considerations of robustness and efficiency, M may be a range other than a fixed value, for example, the value range of M corresponding to transmission mode 1 is 1-2, and the value range of M corresponding to transmission mode 2 is 1-4; the value range of M corresponding to the transmission mode 3 is 3-4;
and/or the value range of the M is determined according to the type of a Downlink Control Information Format (DCI Format) of the M; because different DCI formats may correspond to different transmission mode sets, the value and/or value range of M may also have a relationship with the DCI Format type of M, for example, the value range of M corresponding to DCI Format type I is 1-2, and the value range of M corresponding to type II is 1-4;
and/or the value range of the M is determined according to whether the current data information to be transmitted is retransmitted or not; for example, whether the current data information to be transmitted is retransmitted or not is judged, if the current data information to be transmitted is not retransmitted, M is equal to 1, and if the current data information to be transmitted is retransmitted, M is equal to M, wherein M is an integer greater than 1; or if the current data information to be transmitted is not retransmitted, M is equal to M, wherein M is an integer greater than 1, and if the current data information to be transmitted is retransmitted, M is equal to 2M;
and/or the value range of the M are determined according to the retransmission times of the current data information to be transmitted; for example, the retransmission times of the current data information to be transmitted are judged, if the current data information to be transmitted is transmitted for the first time, M is equal to M, wherein M is an integer greater than or equal to 1; if the current data information to be transmitted is the nth retransmission, M is equal to (n +1) M, wherein n is an integer greater than or equal to 1;
and/or the value range of the M are determined according to the recommended value and/or the value range of the M fed back by the terminal;
and/or the value range of the M are determined according to Channel State Information (CSI) fed back by the terminal; if the CSI of the M paths and/or beam directions are relatively close, the M beams can be used for transmission without significant transmission performance degradation, but multipath diversity gain is brought;
and/or the value range of the M are determined according to a determination rule of the value and/or the value range of the M agreed with the terminal in advance;
and/or the value range of the M are determined according to the frequency used for communication; for example, when the base station and the terminal communicate using frequencies such as 450MHz, 2GHz, 6GHz, 32GHz, 70GHz, and the like, the value and/or the value range of the MM are different, and it can be understood that the larger the frequency used for communication is, the larger the value and/or the value range of M is.
After step 404, the base station may further send, to the terminal, configured indication information for performing channel state information measurement and feedback by using information carried in the M sub-information blocks; the base station can measure which beam channel has better or poorer quality through the feedback of the terminal, so as to better find the accurate beam direction, discriminate some invalid beams, avoid the waste of sending resources and reduce the value and/or the value range of M in the next transmission.
In the information processing method provided by the embodiment of the present invention, a base station encodes information to be transmitted, and divides the encoded code block information into M sub code blocks to be transmitted, where the type of the information to be transmitted is data information or control information; determining M sub-information blocks, wherein the sub-information blocks comprise the sub-code blocks and demodulation pilot resources associated with the sub-code blocks; modulating the M sub-information blocks, and mapping the modulated M sub-information blocks to M time domain resource groups and/or space domain resource groups for sending; informing a terminal of the value and/or the value range of M, wherein M is an integer greater than or equal to 1; the method of the embodiment of the invention improves the transmission efficiency, the link quality and the robustness of the system by adjusting the sending resources.
Fig. 7 is a flowchart of a second embodiment of the information processing method of the present invention, which is illustrated from the perspective of uplink transmission of information from a terminal to a base station in the embodiment of the present invention; as shown in fig. 7, the information processing method provided in the embodiment of the present invention includes the following steps:
The terminal receives indication information sent by a base station, where the indication information carries a value and/or a value range of M determined by the base station, and specifically, the base station may determine the value and/or the value range of M according to the following manner.
The value and/or value range of the M is determined according to a transmission mode; different values of M may be available in different transmission modes, because different transmission modes correspond to different considerations of robustness and efficiency, M may be a range other than a fixed value, for example, the value range of M corresponding to transmission mode 1 is 1-2, and the value range of M corresponding to transmission mode 2 is 1-4; the value range of M corresponding to the transmission mode 3 is 3-4;
and/or the value range of the M are determined according to the DCI Format type of the M; because different DCI formats may correspond to different transmission mode sets, the value and/or value range of M may also have a relationship with the DCI Format type of M, for example, the value range of M corresponding to DCI Format type I is 1-2, and the value range of M corresponding to type II is 1-4;
and/or the value range of the M is determined according to whether the current data information to be transmitted is retransmitted or not; for example, whether the current data information to be transmitted is retransmitted or not is judged, if the current data information to be transmitted is not retransmitted, M is equal to 1, and if the current data information to be transmitted is retransmitted, M is equal to M, wherein M is an integer greater than 1; or if the current data information to be transmitted is not retransmitted, M is equal to M, wherein M is an integer greater than 1, and if the current data information to be transmitted is retransmitted, M is equal to 2M;
and/or the value range of the M are determined according to the retransmission times of the current data information to be transmitted; for example, the retransmission times of the current data information to be transmitted are judged, if the current data information to be transmitted is transmitted for the first time, M is equal to M, wherein M is an integer greater than or equal to 1; and if the current data information to be transmitted is the nth retransmission, M is equal to (n +1) M, wherein n is an integer greater than or equal to 1.
And/or the value range of the M are determined according to the frequency used for communication; for example, when the base station and the terminal communicate using frequencies such as 450MHz, 2GHz, 6GHz, 32GHz, 70GHz, and the like, the value and/or the value range of the MM are different, and it can be understood that the larger the frequency used for communication is, the larger the value and/or the value range of M is.
Firstly, a terminal encodes information to be transmitted according to indication information transmitted by the base station, wherein the type of the information to be transmitted is data information or control information.
Specifically, the terminal encodes the information to be transmitted and performs code block grouping on the basis of the indication information transmitted by the base station, and once the base station finds that the uplink is unreliable in uplink transmission, including a data link and a control link, the transmission strategy needs to be adjusted, specifically, the value and/or the value range of M and the size of the resource group corresponding to each sub-code block can be adjusted.
The terminal adopts a channel coding method to code the information to be sent according to the coding rate; the coding rate determines the redundancy of information, and the value and/or the value range of the coding rate are determined according to the value and/or the value range of the M; the channel coding method comprises a plurality of simple channel coding methods such as a repeated coding method, a turbo coding method, an LDPC coding method and a convolution coding method.
For example, when M is equal to 2, the coding rate is required to be 1/2, or the range of coding rates is a possible coding rate less than or equal to 1/2; when M is equal to 3, the coding rate is required to be 2/M or the range of the coding rate is the possible coding rate less than or equal to 2/M; it can be summarized that the coding rate is less than or equal to f (M), where f (M) is a function with a domain of M, and preferably, f (M) is equal to 1/M.
In addition, the encoding method is determined according to the value and/or the value range of the M; for example, when M is equal to 1, the channel coding method is a Turbo coding method or an LDPC coding method; when the M is larger than 1, the channel coding method is a repetition coding method of M times.
And secondly, the terminal divides the coded code block information into M sub code blocks to be sent according to the indication information sent by the base station.
Specifically, the base station divides the coded code block information into M sub code blocks to be sent; preferably, the division of the sub-code blocks needs to ensure that each sub-code block has some information after coding to indicate the same information before coding; in addition, there are various dividing ways, preferably, each sub-code block is encoded according to the same bit before encoding, but there is a special case that the contents transmitted by the sub-code blocks are the same; more practically, each encoded sub-code block has different content, but all the encoded sub-code blocks belong to the sub-code blocks representing the same information, and preferably, M sub-code blocks may include part or all of the same information to be transmitted, and the content of the M sub-code blocks may also be the same; the coding methods may be the same or different or may not be coded here (understood as a special coding method, i.e. direct mapping).
After step 702, the terminal determines, according to the received indication information of the configured demodulation pilot resources associated with the sub-code block sent by the base station, the configuration of the demodulation pilot resources associated with the sub-code block, which may be specifically used for demodulating sub-code block information or performing measurement of channel state information.
The terminal determines M sub-information blocks, wherein the sub-information blocks comprise the sub-code blocks and demodulation pilot resources associated with the sub-code blocks.
Specifically, each sub-code block uses a group of demodulation pilot frequency resources for transmission, the demodulation pilot frequency resources used by each sub-code block may be the same or different, and the demodulation pilot frequency resources include space domain resources and/or time domain resources; the time domain resources include: at least one of a subframe, a slot, and a time domain symbol; the spatial domain resources include: at least one of antenna port, layer, sector, beam; for example, a set of demodulation pilot resources may include one or more antenna ports in the spatial domain and one or more time domain symbols in the time domain.
After step 703, the terminal configures the M time-domain resource groups and/or space-domain resource groups according to the received indication information of the configured M time-domain resource groups and/or space-domain resource groups sent by the base station; or the terminal determines the M time domain resource groups and/or the space domain resource groups according to a predetermined division rule and the value of the M.
The terminal can also determine resources included in the time domain resource group and/or the space domain resource group according to the value and/or the value range of the M.
For example, the base station may indicate such information, such as value information indicating M; indicating resource location information for the M time-domain resource groups and/or the space-domain resource groups; or only the value of M is indicated, and M time domain resource groups and/or space domain resource groups are determined according to a predetermined division rule and the value of M; the former has more flexibility and the latter saves some overhead.
And 704, mapping the M sub-information blocks to M time domain resource groups and/or space domain resource groups after modulation, and sending the M sub-information blocks.
The terminal can accurately know which resources belong to the same group and which resources belong to different groups at which positions to perform channel detection according to the M time domain resource groups and/or space domain resources determined by the steps; modulating the M sub-information blocks, and mapping the modulated M sub-information blocks to M time domain resource groups and/or space domain resource groups for sending; the transmission resources used by each sub-code block may be the same or different.
