It should be understood that FIG. 1 is only a simplified schematic diagram for ease of understanding. The communication system 100 may also include other devices, which are not shown in FIG. 1 .

Currently, in communication systems, terminal equipment uses a receiver including 8 antennas to receive downlink data to improve the spectrum efficiency of downlink transmission in the communication system. Compared with the 4R receiver, the 8R receiver can not only significantly improve the downlink throughput of a single user in the cell, but also increase the coverage of users at the edge of the cell.

Figure 2 shows a schematic diagram of the architecture of an 8R receiver. As shown in Figure 2, the receiver (terminal equipment) includes 8 antennas. The signal model of this receiver is as follows:

Y＝HWX+n，

Among them, Y is the signal received by the receiver, H is the channel matrix, W is the precoding matrix, X is the signal transmitted by the transmitter, and n is the noise of the receiver.

When the 8R receiver shown in Figure 2 communicates with a network device (for example, the terminal device 120 in Figure 1 is an 8-antenna terminal device), the downlink forwarding process is as follows:

CSI reporting: The network device configures a report configuration for the terminal device.

The reporting indication corresponds to the 8R receiver and is used to indicate the measurement information to be reported by the terminal device; The terminal device sends a CSI report based on the received report configuration. The CSI report includes a CSI. The CSI is obtained based on the reporting indication and CSI-RS measurement and corresponds to the entire 8R receiver.

Physical downlink shared channel (PDSCH) transmission: When the number of transmission streams is less than 4 streams, single codeword transmission is used; when the number of transmission streams is greater than 4, two codeword transmission is used.

If high-flow data needs to be transmitted, it is difficult to implement and has high computational complexity when using the 8R receiver as shown in Figure 2 for data reception and processing.

In view of this, embodiments of the present application provide a communication method and related devices by dividing the eight receiving antennas included in the terminal device into a first antenna set and a second antenna set, and configuring corresponding antenna sets for the two antenna sets. The CSI reporting instruction enables the terminal device to report the first CSI report and the second CSI report respectively corresponding to the two antenna sets when reporting the CSI report, so that each antenna set can receive and process data independently, effectively reducing the The computational complexity of the receiver.

Before introducing the communication method provided by this application, the following points should be explained.

First, in this application, “instruction” may include direct instruction and indirect instruction, as well as explicit instruction and implicit instruction. The information indicated by a certain information is called information to be indicated. In the specific implementation process, there can be many ways to indicate the information to be indicated. For example, but not limited to, the information to be indicated can be directly indicated, such as indicating the information to be indicated itself. Or the index of the information to be indicated, etc. The information to be indicated may also be indirectly indicated by indicating other information, where there is an association relationship between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved by means of a pre-agreed (for example, protocol stipulated) arrangement order of each piece of information, thereby reducing the indication overhead to a certain extent.

Second, in the embodiments shown in this article, various terms and English abbreviations, such as CSI, reporting configuration, reporting instructions, etc., are illustrative examples given for convenience of description and should not constitute any limitation on this application. This application does not exclude the possibility of defining other terms that can achieve the same or similar functions in existing or future agreements.

Fourth, in the embodiments shown below, "predefinition" can be achieved by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in devices (for example, including terminal devices and network devices), This application does not limit its specific implementation.

Fifth, the "protocol" involved in the embodiments of this application may refer to a standard protocol in the communication field, which may include, for example, LTE protocol, NR protocol, and related protocols applied in future communication systems. This application does not limit this.

Sixth, "multiple" means two or more. "And/or" describes the association of associated objects, indicating that there can be three relationships, for example, A and/or B, which can mean: A exists alone, A and B exist simultaneously, and B exists alone, where A, B can be singular or plural. The character "/" generally indicates that the related objects are in an "or" relationship. "At least one of the following" or similar expressions thereof refers to any combination of these items, including any combination of a single item (items) or a plurality of items (items). For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c, where a, b, c can be single or multiple.

The communication method provided by the embodiment of the present application will be described in detail below with reference to FIG. 3 . This method can be applied to the communication system 100 shown in Figure 1, but the embodiment of the present application is not limited thereto. In FIG. 3 , the terminal device and the network device are used as the execution subjects of the interaction gesture as an example to illustrate the method, but this application does not limit the execution subjects of the interaction gesture. For example, the terminal device in Figure 3 can also be a chip, chip system, or processor that supports the terminal device to implement the method, or can be a logic module or software that can realize all or part of the functions of the terminal device; the network in Figure 3 The device may also be a chip, chip system, or processor that supports the network device to implement the method, or may be a logic module or software that can realize all or part of the network device functions.

Figure 3 is a schematic flow chart of a communication method 300 provided by an embodiment of the present application. As shown in Figure 3, the method 300 may include S301 to S303. Each step shown in Figure 3 will be introduced in detail below.

S301. The terminal device determines a first antenna set and a second antenna set. The first antenna set includes M receiving antennas. The second antenna set includes 8-M receiving antennas. 0<M<8, and M is a positive integer. .

Among them, M can take any value from 1 to 7. For example, the number of antennas included in the first antenna set and the second antenna set can be in the following seven ways:

1. M=1, the first antenna set includes 1 receiving antenna, and the second antenna set includes 7 receiving antennas.

2. M=2, the first antenna set includes 2 receiving antennas, and the second antenna set includes 6 receiving antennas.

3. M=3, the first antenna set includes 3 receiving antennas, and the second antenna set includes 5 receiving antennas.

4. M=4, the first antenna set includes 4 receiving antennas, then the second antenna set includes 4 receiving antennas.

5. M=5, the first antenna set includes 5 receiving antennas, and the second antenna set includes 3 receiving antennas.

6. M=6, the first antenna set includes 6 receiving antennas, and the second antenna set includes 2 receiving antennas.

7. M=7, the first antenna set includes 7 receiving antennas, and the second antenna set includes 1 receiving antenna.

It should be understood that there may be multiple ways of grouping antennas in each mode. Taking M=4 as an example, the antenna grouping situation will be described in detail below with reference to Figure 4.

Figure 4 shows the architecture of an 8-antenna receiver provided by an embodiment of the present application. As shown in Figure 4, the 8 receiving antennas of the 8R receiver are divided into two groups, each corresponding to an antenna set, and each antenna set corresponds to a demodulation module. Among them, receiving antennas 1 to 4 belong to the first antenna set, corresponding to In the first demodulation module, the receiving antennas 5 to 8 belong to the second antenna set and correspond to the second demodulation module. For example, each grouped antenna set can be regarded as a 4R receiver.

It should be understood that the above demodulation module is used to process the data stream received by the antenna set. For example, the first demodulation module is used to process the data stream received by the first set of antennas, and the second demodulation module is used to process the data stream received by the second set of antennas.

It should also be understood that the above-mentioned grouping manner of receiving antennas is only an example. For example, when M=4, the first antenna set includes receiving antennas 1, 3, 5, and 7, and the second antenna set includes 2, 4, 6, and 8; or when M=3, the first antenna set includes receiving antennas 1~ 3. The second antenna set includes 4 to 8; or other combinations. This application does not limit this.

As shown in Figure 4, the signal model of the receiver is as follows:

Right now,

Among them, Y ₁ is the signal received by the first antenna set, H ₁ is the channel matrix measured based on the CSI-RS received by the first antenna set, W ₁ is the precoding matrix of the first antenna set, and X ₁ is the network device The transmitted signal, n ₁ is the noise vector of the first antenna set. Y ₂ is the signal received by the second antenna set, H ₂ is the channel matrix measured based on the CSI-RS received by the second antenna set, W ₂ is the precoding matrix of the second antenna set, and X ₂ is the transmission of the network device signal, n ₂ is the noise of the second antenna set.

In one implementation, the terminal device may determine the first antenna set and the second antenna set based on a preset rule.

Wherein, the preset rule indicates M receiving antennas included in the first antenna set and/or 8-M receiving antennas included in the second antenna set. Alternatively, the preset rule indicates the corresponding relationship between the eight receiving antennas and the first antenna set and the second antenna set. In other words, the preset rule indicates the corresponding relationship between the first antenna set and the second antenna set and the eight receiving antennas.

It should be understood that the above preset rules may be rules negotiated between the terminal device and the network device during the configuration phase; they may also be rules negotiated and determined during the signaling interaction process. It can be set manually, based on historical data, or based on big data analysis. This application does not limit the setting method of the above preset rules.

Illustratively, the above preset rule is: the first antenna set includes receiving antennas with antenna numbers 1 to 4, and the second antenna set includes receiving antennas with antenna numbers 5 to 8; or, the first antenna set includes antennas with antenna numbers 5 to 8. 1, 3, 5, and 7 receiving antennas, the second antenna set includes receiving antennas with antenna numbers 2, 4, 6, and 8; or, the first antenna set includes receiving antennas with antenna numbers 1, 2, 5, and 6. , the second antenna set includes receiving antennas with antenna numbers 3, 4, 7, and 8; or, the first antenna set includes receiving antennas with antenna numbers 3, 4, 5, and 6, and the second antenna set includes antennas with antenna numbers 1 , 2, 7, 8 receiving antennas. Among them, 1 to 8 are the numbers of the eight receiving antennas.

It should be understood that the above preset rules only show some combinations of the first antenna set and the second antenna set when M=4, and do not constitute a limitation on the two antenna sets in the embodiment of the present application.

In another implementation manner, the terminal device may determine the first antenna set and the first antenna set based on instructions from the network device. Exemplarily, the network device determines the first antenna set and the second antenna set, and sends first indication information to the terminal device, used to indicate the M receiving antennas included in the first antenna set and/or the 8 receiving antennas included in the second antenna set. -M receiving antennas. Correspondingly, the terminal device receives the first indication information, and determines the first antenna set and the second antenna set based on the first indication information.

For example, the network device can divide the eight receiving antennas of the terminal device into two groups based on the following steps:

Step 1: Based on formula (1), determine the receiving antenna i from the 8 receiving antennas:

i=max _i ((HH ^H ) ^_1 ) _{i, i} (1)

Step 2: Based on formula (2), determine the three antennas with strong channel correlation with antenna i:

max _j，j≠i ((HH ^H ) ^-1 ) _i，j (2)

Among them, H represents the channel matrix of 8 receiving antennas, and i and j are the antenna numbers.

The four antennas determined based on formula (1) and formula (2) are regarded as an antenna set, for example, the first antenna set or the second antenna set, and the remaining four antennas are regarded as an antenna set.

S302: The network device sends a first CSI reporting indication and a second CSI reporting indication to the terminal device. The first CSI reporting indication corresponds to the first antenna set, and the second CSI reporting indication corresponds to the second antenna set. Correspondingly, the terminal device receives the first CSI reporting indication and the second CSI reporting indication.

Wherein, the first CSI reporting indication and the second CSI reporting indication are associated with CSI-RS. That is to say, when the terminal device performs CSI measurement reporting, the network device needs to send the first CSI reporting indication, the second CSI reporting indication and the CSI-RS to the terminal device.

The correspondence between the above first CSI reporting indication and the first antenna set can be understood as the first CSI reporting indication is configured by the network device for the first antenna set, and the correspondence between the above second CSI reporting indication and the second antenna set can be understood as the second CSI reporting Indicates that the network device is configured for the second set of antennas. That is, the first CSI reporting indication is used to indicate the measurement information that needs to be reported by the first antenna set, and the second CSI reporting indication is used to indicate the measurement information that needs to be reported by the second antenna set.

It should be understood that the above reporting indication is used to indicate the type of measurement information reported by the terminal device, for example, PMI information, channel quality indicator (channel quality indicator, CQI) information, RI information, or layer indicator (layerindicator, LI) information, etc.

S303: The terminal device sends a first CSI report and a second CSI report to the network device. The first CSI report corresponds to the first antenna set, and the second CSI report corresponds to the second antenna set. Correspondingly, the network device receives the first CSI report and the second CSI report.

The first CSI report is determined based on the first CSI reporting indication and CSI-RS, and the second CSI report is determined based on the second CSI reporting indication and CSI-RS. That is, the first CSI report is that the first antenna set determines the type of measurement information in the CSI report based on the first CSI reporting indication; the second CSI report is that the second antenna set determines the measurement information in the CSI report based on the second CSI reporting indication. Type of information; determine the measurement information in the CSI report based on CSI-RS.

The following describes the process of determining the measurement information in the CSI report based on CSI-RS in two situations. For example, the above-mentioned first CSI report includes a first RI (for example, denoted as RI ₁ ), and the second CSI report includes a second RI (for example, denoted as RI ₂ ). Alternatively, the first CSI report includes a first RI (for example, RI ₁ ) and a first PMI (for example, PMI ₁ ), and the second CSI report includes a second RI (for example, RI ₂ ) and a second PMI (for example, PMI 1 ). PMI (for example, denoted as PMI ₂ ).

In case 1, the two antenna sets on the terminal device cannot interact, then RI ₁ , PMI ₁ , RI ₂ and PMI ₂ are determined based on CSI-RS.

The fact that the two antenna sets cannot interact can be understood to mean that the two demodulation modules corresponding to the two antenna sets are independent of each other, that is, the terminal equipment can be regarded as two independent 4R receivers. Therefore, in this case, the calculation of the measurement information about CSI on each demodulation module can be independent of each other. You can refer to the calculation of the measurement information about CSI in the existing 4R receiver or the 8R receiver shown in Figure 2. The process will not be described again here.

In case two, two antenna sets on the terminal device can interact, then RI ₁ , PMI ₁ , RI ₂ and PMI ₂ are based on the interaction information between the first antenna set and the second antenna set and CSI-RS definite.

The fact that the two antenna sets can interact can be understood to mean that the demodulation modules corresponding to the two antenna sets can interact, that is, the information (such as channel information) on the two demodulation modules can be sent to each other to the other demodulation module. Therefore, in case 2, the measurement information in the first CSI report and the second CSI report may be based on the interaction between the first antenna set (first demodulation module) and the second antenna set (second demodulation module) information as well as determined by CSI-RS.

The above interactive information can be understood as channel information, that is, the two antenna sets measure H ₁ and H ₂ respectively based on the received CSI-RS, and the first antenna set can obtain H 2 measured by the second antenna set, and the second antenna set can obtain H ₂ measured by the second antenna set. H ₁ measured by the first antenna set can be obtained. Wherein, H ₁ is a channel matrix measured based on the CSI-RS received by the first antenna set, and H ₂ is a channel matrix measured based on the CSI-RS received by the second antenna set.

For example, when two antenna sets can interact, RI ₁ , RI ₂ , PMI ₁ and PMI ₂ can be determined based on the following formula:

Among them, W ₁ is the precoding matrix of the first antenna set, W ₂ is the precoding matrix of the second antenna set, σ ² is the noise power, PMI ₁ is used to indicate W ₁ , and PMI ₂ is used to indicate W ₂ .

Optionally, the value ranges of RI ₁ and RI ₂ in the above formula are agreed upon by the protocol, configured by the network device for the terminal device, or determined by the terminal device.

It should be understood that when the value range of RI ₁ and RI ₂ is determined by the terminal device, the terminal device may send the determined value range to the network device or not, and this application does not limit this.

For example, the value range of (RI ₁ , RI ₂ ) agreed in the agreement may be: (1,1), (1,2), (2,1), (2,2), (2,3), (3,2)(3,3), (3,4), (4,3), (4,4). Further, the terminal device uses the above formula to traverse each set of values of (RI ₁ , RI ₂ ), and obtains the value of each set of values, The optimal solution of this function is W ₁ and W ₂ . Based on the above calculation method, multiple groups of RI ₁ , RI ₂ , PMI ₁ and PMI ₂ can be determined (that is, each group of RI values corresponds to one group of PMI). After determining multiple groups of RI ₁ , RI ₂ , PMI ₁ and PMI ₂ After the values are obtained, a set of values that maximizes the above function value can be determined based on multiple sets of values, and the set of values can be reported to the network device.

It should be understood that the above determination of RI ₁ , RI ₂ , PMI ₁ and PMI ₂ may be performed by the first demodulation module and/or the second demodulation module on the terminal device. For example, RI ₁ , RI ₂ , PMI ₁ and PMI ₂ are determined by the first demodulation module, then the first demodulation module sends RI ₂ and PMI ₂ to the second demodulation module; RI ₁ , RI ₂ , PMI ₁ And PMI ₂ is determined by the second demodulation module, then the second demodulation module sends RI ₁ and PMI ₁ to the first demodulation module.

It should be noted that the above function is related to spectrum efficiency, that is, the communication system has higher requirements for spectrum effect, then the above formula can be used to determine RI and PMI; if the communication system has higher requirements for transmission capacity, then the transmission capacity can be used Related formulas determine RI and PMI. In other words, RI and PMI can be determined using different calculation formulas according to the requirements of the communication system. This application does not limit the methods used to calculate RI and PMI.

In the embodiment of the present application, after the network device and the terminal device determine the antenna set, the network device configures the reporting instruction for each antenna set for the terminal device, so that the terminal device that receives the reporting instruction can communicate with the third party based on the reporting instruction and CSI-RS report. The CSI reports corresponding to one antenna set and the second antenna set enable the two antenna sets on the terminal device to process their respective received data streams, effectively reducing the computational complexity of the terminal device when processing the data stream.

As an optional embodiment, before S301, the method 300 further includes: the terminal device sending capability information of the terminal device to the network device, where the capability information is used to indicate that the terminal device includes two antenna sets. Correspondingly, the network device receives the capability information.

It should be understood that the terminal device indicated by the above capability information includes two antenna sets, which can be understood to mean that the terminal device includes two demodulation modules, or that the terminal device can support using two antenna sets to demodulate received signals respectively. Among them, the demodulation module is used to demodulate the data stream received by the terminal device.

The above two demodulation modules may be called a first demodulation module and a second demodulation module respectively, wherein the first demodulation module may be used to process the data stream received on the first antenna set, and the second demodulation module may It is used to process the data stream received by the second antenna set, and the receiving antennas included in the first antenna set and the receiving antennas included in the second antenna set are different.

As an optional embodiment, the first CSI reporting indication and the second CSI reporting indication are carried in the same reporting setting (reporting setting); the first CSI report and the second CSI report are carried in the same PUCCH.

As an optional embodiment, the first CSI reporting indication and the second CSI reporting indication are respectively carried in different reporting configurations; the first CSI report and the second CSI report are carried in different PUCCHs respectively.

For example, the network device sends a reporting setting to the terminal device. The reporting setting includes two CSI reporting instructions and corresponds to two antenna sets respectively. Alternatively, the network device sends two reporting settings to the terminal device, and each reporting setting includes a CSI reporting indication corresponding to an antenna set. Among them, the specific description of the reporting setting can refer to the existing protocol and will not be described again here.

Combined with the above example, when two CSI reporting instructions are carried in the same reporting setting, the CSI report reported by the terminal device can be carried and fed back on a PUCCH. When the two CSI reporting instructions are carried in two reporting settings respectively, the two CSI reports reported by the terminal device can be carried on two PUCCHs respectively for feedback, that is, one PUCCH carries one CSI report.

As an optional embodiment, the method 300 further includes: the network device sends second indication information, the second indication information is used to indicate the connection between the data stream to be transmitted and the first antenna set and/or the second antenna set. Correspondence. Correspondingly, the terminal device receives the second indication information.

Optionally, the network device sends the data stream to be transmitted. Correspondingly, the terminal device receives the data stream to be transmitted, and determines the data stream received by the first antenna set and/or the second antenna set based on the second indication information.

As an optional embodiment, the method 300 further includes: the network device sending third indication information, the third indication information being used to indicate the correspondence between the data stream to be transmitted and the codeword. Correspondingly, the terminal device receives the third indication information.

It should be noted that the precoding methods for data streams to be transmitted received by the same antenna set are the same, but the encoding methods may be different, that is, the data streams received by the same antenna set may correspond to different codewords. Therefore, the terminal device needs to further determine the corresponding relationship between the data stream and the codeword, so as to decode the data stream.

Illustratively, the network device sends a data stream to be transmitted. Correspondingly, the terminal device receives the data stream; the terminal device determines the data stream received by the first antenna set and the second antenna set based on the second indication information; and determines the encoding method used for the received data stream based on the third indication information; The first demodulation module and the second demodulation module on the terminal device respectively decode the received data stream using a decoding method corresponding to the encoding method.

The first demodulation module is used to process the data stream received by the first antenna set, and the second demodulation module is used to process the data stream received by the second antenna set.

Optionally, when the first antenna set and the second antenna set cannot interact, the network device and the terminal device can determine the codewords corresponding to the first antenna set and the second antenna set through protocol agreement or preconfiguration. . For example, it is determined that the first set of antennas receives the data stream of codeword 0, and the second set of antennas receives the data stream of codeword 1.

For example, the codeword corresponding to the first antenna set is codeword 0, and the codeword corresponding to the second antenna set is codeword 1. That is, when the network device sends a data stream to the terminal device, it needs to send the data stream with codeword 0 to the first antenna set and the data stream with codeword 1 to the second antenna set. In this way, when the terminal device receives the data stream, the first antenna set and/or the second antenna set can decode the received data stream based on the corresponding relationship between the above-mentioned antenna set and the codeword.
