In the present disclosure, a network device may provide communication coverage for a particular geographic area and may communicate with terminals located within that coverage area (cell). In addition, in the case of a vehicle networking (V2X) communication system, the network device may also be an in-vehicle device.

Based on this, the embodiment of the disclosure provides a method for reporting channel state information, where a terminal receives first configuration information sent by a network device, where the first configuration information is used to configure at least one CMR, and the at least one CMR includes N channel state information reference signal (Channel State Information Reference Signal, CSI-RS) resources. Therefore, in a coherent joint transmission scene with multiple transmitting and receiving points, the terminal can perform CSI measurement based on CMR configuration, and the transmission performance of multiple TRPs is improved.

Fig. 2 is a flowchart of a method for reporting channel state information according to an exemplary embodiment, and as shown in fig. 2, the method for reporting channel state information is used in a terminal, and includes the following steps.

In step S11, first configuration information sent by a network device is received, where the first configuration information is used to configure at least one CMR, where the at least one CMR includes N CSI-RS resources, and N is an integer greater than 1.

Wherein the N CSI-RS resources correspond to N TRPs. That is, the network device indicates CSI-RS resources corresponding to the N TRPs.

In the embodiment of the disclosure, the terminal receives first configuration information sent by the network device, where the first configuration information is used to configure at least one CMR, and the at least one CMR includes N CSI-RS resources. Therefore, in a coherent joint transmission scene with multiple transmitting and receiving points, the terminal can perform CSI measurement based on CMR configuration, and the transmission performance of the multiple transmitting and receiving points is improved.

Fig. 3 is a flowchart illustrating a channel state information reporting method according to an exemplary embodiment, as shown in fig. 3, including the following steps.

In step S21, second configuration information sent by the network device is received, where the second configuration information is used to configure at least one spatial base vector combination and a combination index corresponding to the at least one spatial base vector combination, where the at least one spatial base vector combination includes a number of spatial base vectors corresponding to each of the N CSI-RS resources.

Wherein the spatial basis vector may also be referred to as beam.

In some embodiments, the spatial basis vector is associated with at least one of N1, N2, O1, O2. Wherein N1 is the number of antenna ports in the first dimension, N2 is the number of antenna ports in the second dimension, O1 is the oversampling rate in the first dimension, and O2 is the oversampling rate in the second dimension. Where the antenna port number may be understood as the port number of the CSI-RS.

For example, the selection of the spatial basis vectors may be understood as selecting a specified number of spatial basis vectors from the total number of antenna ports N1×n2 of each CSI-RS resource, respectively.

In the embodiment of the present disclosure, the second configuration information is configured to configure at least one spatial base vector combination and a combination index corresponding to the at least one spatial base vector combination, so that after determining the number of spatial base vectors corresponding to each CSI-RS resource, the terminal may determine a combination index corresponding to the spatial base vector combination corresponding to the number of spatial base vectors corresponding to the N CSI-RS resources.

It should be noted that the embodiment shown in fig. 2 may be implemented separately, that is: when the embodiment shown in fig. 2 is implemented separately, the terminal may receive first configuration information sent by the network device for configuring at least one CMR; but, whether to receive the second configuration information for configuring the at least one spatial base vector combination and the combination index corresponding to the at least one spatial base vector combination, or in what manner to determine the at least one spatial base vector combination and the combination index corresponding to the at least one spatial base vector combination, the embodiment of the disclosure is not limited thereto. The embodiment shown in fig. 2 may also be implemented in conjunction with other embodiments of the present disclosure, such as in conjunction with the embodiment shown in fig. 3; namely: the terminal can receive first configuration information sent by the network equipment and used for configuring at least one CMR; and the terminal also receives second configuration information sent by the network equipment and used for configuring at least one spatial base vector combination and a combination index corresponding to the spatial base vector combination. In the embodiments of the present disclosure, the first configuration message and the second configuration message may be carried in different signaling or the same signaling, which is not limited by the embodiments of the present disclosure.

Fig. 4 is a flowchart illustrating a channel state information reporting method according to an exemplary embodiment, as shown in fig. 4, including the following steps.

In step S31, N CSI-RS resources are measured based on the first configuration information and/or the second configuration information, and the first indication information and/or the second indication information are determined.

The first indication information is used for indicating target CSI-RS resources and/or non-target CSI-RS resources in the N CSI-RS resources, and the second indication information is used for indicating at least one combined index.

In some embodiments, the spatial basis vector combinations corresponding to the combined indexes indicated by the second indication information are used to determine the number of spatial basis vectors corresponding to the target CSI-RS resources.

It should be noted that, the terminal may implicitly determine the combination index corresponding to the at least one spatial base vector combination, so that the terminal may determine the second indication information by measuring the N CSI-RS resources based on the first configuration information without second configuration information sent by the network device.

For example, when the terminal determines, based on configuration information of the network device or a default rule, that the candidate values of the number of space-domain basis vectors corresponding to each CSI-RS resource are 2,4, and 6, if the number of CSI-RS resources included in one CMR is 2, the space-domain basis vector combinations may include the following 9 combinations and corresponding combination indexes:

Combination 1: {2,2}

Combination 2: {2,4}

Combination 3: {2,6}

Combination 4: {4,2}

Combination 5: {4,4}

Combination 6: {4,6}

Combination 7: {6,2}

Combination 8: {6,4}

Combination 9: {6,6}

Of course, the correspondence of the above-described combinations and the combination indexes is not limited to the correspondence given in the present embodiment.

In the method for reporting channel state information provided by the embodiment of the present disclosure, first indication information and/or second indication information is sent to a network device.

In the embodiment of the disclosure, by measuring the N CSI-RS resources, the number of the target CSI-RS resources or the non-target CSI-RS resources selected by the terminal from the N CSI-RS resources and the number of the space base vectors corresponding to the target CSI-RS resources may be determined, and the combined index corresponding to the space base vector combination corresponding to the number of the space base vectors corresponding to the target CSI-RS resources may be determined, so that after the first indication information and/or the second indication information is sent to the network device, the network device may learn the number of the target CSI-RS resources selected by the terminal and the space base vectors corresponding to the target CSI-RS resources, and improve the transmission performance of the CJT based on multiple TRPs.

In the method for reporting channel state information provided by the embodiment of the present disclosure, the number of space-base vectors corresponding to the target CSI-RS resource is the number of space-base vectors corresponding to the target CSI-RS resource in the space-base vector combination corresponding to the at least one combination index indicated by the second indication information.

For example, the CMR configured by the first configuration information includes 4 CSI-RS resources, the first indication information indicates that the first three CSI-RS resources of the 4 CSI-RS resources are target CSI-RS resources, the last CSI-RS resource is a non-target CSI-RS resource, and the number of spatial base vectors selected by each target CSI-RS resource is 2,4, and 2 respectively. Then the combination index indicated by the second indication information corresponds to {2,4,2,6}, that is, the number of spatial base vectors corresponding to the target CSI-RS resources is 2,4, and 2, respectively.

The combination {2,4,2,6} corresponding to the combination index indicated by the second indication information is a combination configured by the network device through the second configuration information. If the CMR configured by the first configuration information includes N CSI-RS resources, the combination of the second configuration information includes the number of spatial base vectors that may correspond to the N CSI-RS resources. Whether the terminal selects all the N CSI-RS resources as target CSI-RS resources or not, the combination corresponding to the combination index indicated by the second indication information comprises the number of airspace base vectors corresponding to the N CSI-RS resources.

In the method for reporting channel state information provided by the embodiment of the present disclosure, the number of space-domain base vectors corresponding to non-target CSI-RS resources is 0.

It should be noted that, no matter how many space-base vectors the non-target CSI-RS resources correspond to in the combination of the N CSI-RS resource configurations are in the second configuration information or how many space-base vectors the non-target CSI-RS resources correspond to in the combination of the combination indexes indicated by the second indication information are in the combination, the number of space-base vectors the non-target CSI-RS resources actually correspond to is 0.

In the above embodiment, if the terminal selects the partial CSI-RS resource (also referred to as the target CSI-RS resource) configured by the first configuration information, and another partial CSI-RS resource is not selected by the terminal (also referred to as the non-target CSI-RS resource), if the number of the space-base vectors corresponding to each CSI-RS resource included in the CMR is determined only according to the second indication information, the network device needs to consider that the number of the space-base vectors corresponding to the partial CSI-RS resource not selected by the terminal is 0, so the network device needs to configure all combinations of the space-base vector combinations corresponding to all CSI-RS resources for the terminal, where the number of the space-base vectors corresponding to each CSI-RS resource includes 0 and non-0 (e.g. 2,4, 6), which results in a large RRC signaling overhead and a large number of combinations. Meanwhile, the number of bits required for the terminal to indicate the selected combined index in the uplink control information (Uplink Control Information, UCI) is also large, so that the signaling overhead of UCI is also large.

For example, if the number of base vectors other than 0 only includes 2, the number of spatial base vectors selected by the terminal for each target CSI-RS resource is 2, and if the number of spatial base vectors corresponding to the non-target CSI-RS resource is considered to be 0, the bit number required for the combination index indicated by the second indication information must cover the combination indexes corresponding to the following 15 combinations:

{2，2，2，2}，{0，2，2，2}，{0，0，2，2}，{0，0，0，2}，{2，0，2，2}，{2，0，0，2}，{2，0，0，0}，{2，2，0，2}，{2，2，0，0}，{2，2，2，0}，{0，2，0，2}，{0，2，2，0}，{0，0，2，0}，{0，0，2，2}，{0，2，0，0}。

however, if the second indication information is combined with the first indication information, because the space base vectors corresponding to the non-target CSI-RS resources indicated by the first indication information are all 0, it is not necessary to consider how many space base vectors corresponding to the non-target CSI-RS resources are in the space base vector combination corresponding to the combination index indicated by the second indication information, and then the space base vector combination only needs {2, 2} combination to determine the space base vector number corresponding to the target CSI-RS resources. That is, the first indication information indicates the target CSI-RS resource and the non-target CSI-RS resource, and the spatial base vector combination corresponding to the combination index indicated by the second indication information is {2, 2}, then the base station can determine that the number of spatial base vectors corresponding to the target CSI-RS resource is 2, and the number of spatial base vectors corresponding to the non-target CSI-RS resource is 0.

For another example, if the number of base vectors other than 0 includes 2 and 4, the number of spatial base vectors selected by the terminal for each target CSI-RS resource is 2 or 4, and if the number of spatial base vectors corresponding to the non-target CSI-RS resource is considered to be 0, the number of bits required for the combination index indicated by the second indication information must be able to cover the combination indexes corresponding to 81 combinations including 0, 2 and 4:

{2，2，4，4}，{0，2，4，4}，{0，0，4，4}，{2，2，4，2}，{2，0，4，4}，{2，0，4，2}，{4，2，0，0}，{4，2，0，2}，{4，2，0，0}，{4，2，2，0}，{4，2，0，2}…。

however, if the second indication information is combined with the first indication information, because the space base vectors corresponding to the non-target CSI-RS resources indicated by the first indication information are all 0, it is not necessary to consider how many space base vectors corresponding to the non-target CSI-RS resources are in the space base vector combination corresponding to the combination index indicated by the second indication information, and only 16 combinations including 2 and 4 need to be indicated by the space base vector combination indicated by the second indication information, so that the number of combinations corresponding to the combination index indicated by the second indication information is greatly reduced.

According to the embodiment of the disclosure, the first indication information for indicating the target CSI-RS resource and/or the non-target CSI-RS resource is combined with the second indication information for indicating the combined index to indicate the number of the airspace base vectors corresponding to the target CSI-RS resource, no matter how many airspace base vectors corresponding to the non-target CSI-RS resource are in the combination corresponding to the combined index indicated by the second indication information, the number of the airspace base vectors corresponding to the non-target CSI-RS resource is 0, that is, the second indication information only needs to indicate the combined index corresponding to the airspace base vector number corresponding to the target CSI-RS resource, so that the number of the combination corresponding to the combined index indicated by the second indication information is greatly reduced, and signaling cost of the second indication information is saved.

In the method for reporting channel state information provided in the embodiments of the present disclosure, in response to the presence of at least one spatial base vector combination, the number of spatial base vectors corresponding to target CSI-RS resources included in the plurality of spatial base vector combinations is the same, and the number of spatial base vectors corresponding to non-target CSI-RS resources included in the plurality of spatial base vector combinations is different, at least one combination index indicated by the second indication information is determined based on the first rule.

Wherein the first rule may be a preconfigured rule; alternatively, the first rule is a rule specified by the protocol; or, rules indicated by the first device for the network device, etc. The embodiments of the present disclosure are not limited herein.

For example, the CMR configured by the first configuration information includes 4 CSI-RS resources, the terminal selects the last three CSI-RS resources as target CSI-RS resources, the number of space basis vectors corresponding to each target CSI-RS resource is determined to be 2, and the first CSI-RS resource is a non-target CSI-RS resource. However, in the spatial base vector combination in which the second configuration information is configured by 4 CSI-RS resources, there are 2 spatial base vectors corresponding to the last three CSI-RS resources in the multiple spatial base vector combinations, and 2, 4, 6, or the like spatial base vectors corresponding to the first CSI-RS resource. For example: {2,2,2,2},{4,2,2,2},{6,2,2,2}. At this time, the terminal may determine a combination index indicated by the second indication information based on the first rule.

In some embodiments, the first rule comprises:

any one of a plurality of combination indexes corresponding to the plurality of spatial base vector combinations; or (b)

A combination index corresponding to a combination with a smaller combination index value in a plurality of combination indexes corresponding to a plurality of airspace base vector combinations; or (b)

A combination index corresponding to a combination with a larger combination index value in a plurality of combination indexes corresponding to a plurality of airspace base vector combinations; or (b)

Designating a combination index corresponding to a space base vector combination with smaller space base vector number corresponding to a non-target CSI-RS resource in the plurality of space base vector combinations; or (b)

And designating a combination index corresponding to the spatial base vector combination with larger number of spatial base vectors corresponding to the non-target CSI-RS resource from the plurality of spatial base vector combinations.

In an exemplary embodiment, the index indicated by the second indication information is any one of a plurality of combined indexes corresponding to the plurality of spatial base vector combinations.

For example, the plurality of spatial base vectors are combined to {2, 2}, {4,2,2,2}, {6,2,2,2}, and the combination index indicated by the second indication information may be a combination index corresponding to any one of {2, 2}, {4,2,2,2}, and {6,2,2,2} combinations.

In another exemplary embodiment, the index indicated by the second indication information is a combination index corresponding to a combination having a smaller combination index value among a plurality of combination indexes corresponding to a plurality of spatial base vector combinations.

For example, the plurality of spatial basis vectors are combined into {2, 2}, {4,2,2,2}, {6,2,2,2}, wherein the combination index corresponding to {2, 2}, the combination index indicated by the second indication information may be a {2, 2} corresponding combination index.

In another exemplary embodiment, the index indicated by the second indication information is a combination index corresponding to a combination having a larger combination index value among a plurality of combination indexes corresponding to a plurality of spatial base vector combinations.

For example, the plurality of spatial basis vectors are combined to {2, 2}, {4,2,2,2}, {6,2,2,2}, where the combination index corresponding to {6,2,2,2} is larger, and thus the combination index indicated by the second indication information may be the combination index corresponding to {6,2,2,2 }.

In another exemplary embodiment, the index indicated by the second indication information is a combination index corresponding to a combination of spatial basis vectors with a smaller number of spatial basis vectors corresponding to the specified non-target CSI-RS resource.

For example, the plurality of spatial basis vector combinations are {2, 2}, {4,2,2,2}, {6,2,2,2}, and if only the first CSI-RS resource is a non-target CSI-RS resource, the non-target CSI-RS resource is designated as the first CSI-RS resource. Among the three combinations, the spatial base vector combination with smaller spatial base vector number corresponding to the first CSI-RS resource is {2, 2}, so the combination index indicated by the second indication information may be the combination index corresponding to {2,2 }.

In another exemplary embodiment, the index indicated by the second indication information is a combination index corresponding to a spatial base vector combination with a larger number of spatial base vectors corresponding to the specified non-target CSI-RS resource among the plurality of spatial base vector combinations.

For example, the plurality of spatial basis vector combinations are {2, 2}, {4,2,2,2}, {6,2,2,2}, and if only the first CSI-RS resource is a non-target CSI-RS resource, the non-target CSI-RS resource is designated as the first CSI-RS resource. Among the three combinations, the spatial base vector combination with the larger number of spatial base vectors corresponding to the first CSI-RS resource is {6,2,2,2}, so the combination index indicated by the second indication information may be the combination index corresponding to {6,2,2,2 }.

In some embodiments, when there is only one non-target CSI-RS resource, the designated non-target CSI-RS resource includes the one non-target CSI-RS resource.

In some embodiments, when there are multiple non-target CSI-RS resources, designating the non-target CSI-RS resources includes:

all non-target CSI-RS resources; or (b)

Corresponding non-target CSI-RS resources with smaller CSI-RS resource indexes; or (b)

And corresponding non-target CSI-RS resources with larger indexes.

For example, the CMR configured by the first configuration information for the terminal includes 4 CSI-RS resources, the terminal selects the first two CSI-RS resources as target CSI-RS resources, the second two CSI-RS resources are non-target CSI-RS resources, the number of space base vectors corresponding to the first two CSI-RS resources selected by the terminal is 2, and the number of space base vectors corresponding to the second two CSI-RS resources in different space base vector combinations is different, for example, the space base vector combinations are {2, 2}, {2,2,4,2}, {2, 4,6}, {2, 6}, and so on.

The CSI-RS resource index corresponding to the third CSI-RS resource is a first resource index, the CSI-RS resource index corresponding to the fourth CSI-RS resource index is a second resource index, and the first resource index is smaller than the second resource index.

In one embodiment, if the specified non-target CSI-RS resources include all non-target CSI-RS resources, the specified non-target CSI-RS resources may be third and fourth CSI-RS resources. At this time, the index indicated by the second indication information is a combined index corresponding to a combination of the spatial base vectors with smaller number of spatial base vectors corresponding to the third and fourth CSI-RS resources. And the space base vector combinations with smaller space base vector numbers corresponding to the third and fourth CSI-RS resources are {2, 2}, so that the combination index indicated by the second indication information can be the combination index corresponding to {2,2 }.

In another embodiment, if the specified non-target CSI-RS resources include all non-target CSI-RS resources, the specified non-target CSI-RS resources may be third and fourth CSI-RS resources. At this time, the index indicated by the second indication information is a combined index corresponding to a combination of spatial base vectors with a larger number of spatial base vectors corresponding to the third and fourth CSI-RS resources. And the space base vector combinations with larger space base vector numbers corresponding to the third and fourth CSI-RS resources are {2, 6}, so the combination index indicated by the second indication information can be the combination index corresponding to {2, 6 }.

In another embodiment, if the non-target CSI-RS resource is designated as a non-target CSI-RS resource with a smaller index of the corresponding CSI-RS resource, the non-target CSI-RS resource is designated as a third CSI-RS resource. At this time, the index indicated by the second indication information is a combined index corresponding to a spatial base vector combination with a smaller number of spatial base vectors corresponding to the third CSI-RS resource. And the spatial base vector combination with smaller spatial base vector number corresponding to the third CSI-RS resource is {2, 2}, so the combination index indicated by the second indication information may be the combination index corresponding to {2,2 }.

In another embodiment, if the non-target CSI-RS resource is designated as a non-target CSI-RS resource with a smaller index of the corresponding CSI-RS resource, the non-target CSI-RS resource is designated as a third CSI-RS resource. At this time, the index indicated by the second indication information is a combined index corresponding to a spatial base vector combination with a larger number of spatial base vectors corresponding to the third CSI-RS resource. And the spatial base vector combination with larger spatial base vector number corresponding to the third CSI-RS resource is {2, 6}, so the combination index indicated by the second indication information may be the combination index corresponding to {2, 6 }.

In another embodiment, if the non-target CSI-RS resource is designated as a non-target CSI-RS resource with a larger index of the corresponding CSI-RS resource, the non-target CSI-RS resource is designated as a fourth CSI-RS resource. At this time, the index indicated by the second indication information is a combined index corresponding to a spatial base vector combination with a smaller number of spatial base vectors corresponding to the fourth CSI-RS resource. And the spatial base vector combination with smaller spatial base vector number corresponding to the fourth CSI-RS resource is {2, 2}, so the combination index indicated by the second indication information may be the combination index corresponding to {2,2 }.

In another embodiment, if the non-target CSI-RS resource is designated as a non-target CSI-RS resource with a larger index of the corresponding CSI-RS resource, the non-target CSI-RS resource is designated as a fourth CSI-RS resource. At this time, the index indicated by the second indication information is a combined index corresponding to a spatial base vector combination with a larger number of spatial base vectors corresponding to the fourth CSI-RS resource. And the spatial base vector combination with larger number of spatial base vectors corresponding to the fourth CSI-RS resource is {2, 6}, so the combination index indicated by the second indication information can be the combination index corresponding to {2, 6 }.

In the embodiment of the present disclosure, when the number of space base vectors corresponding to the target CSI-RS resource included in the plurality of space base vector combinations is the same, since the number of space base vectors corresponding to the non-target CSI-RS resource is 0, no matter which combination index is indicated by the second indication information, the network device may know the number of space base vectors corresponding to the target CSI-RS resource, and the embodiment of the present disclosure may specify, through the first rule, which combination index indicated by the second indication information is, so as to determine the behavior of the terminal.

It should be noted that, the smaller or larger related to the above embodiment may not only represent the minimum or maximum, but also represent the second minimum, the third minimum, and so on, and may determine the combination index specifically indicated by the first rule according to the actual application scenario, so as to determine the behavior of the terminal.

In the method for reporting channel state information provided by the embodiment of the present disclosure, the first indication information includes N bits, each bit in the N bits corresponds to one CSI-RS resource in the N CSI-RS resources, and different values of each bit are used to indicate that the corresponding one CSI-RS resource is a target CSI-RS resource or a non-target CSI-RS resource.

For example, when the bit value is the first value, the CSI-RS resource is indicated as the target CSI-RS resource. And when the bit value is the second value, the CSI-RS resource is a non-target CSI-RS resource.

Wherein the first value is 0 and the second value is 1. Or, the first value is 1 and the second value is 0.

In the method for reporting channel state information provided in the embodiments of the present disclosure, first indication information and second indication information are carried in CSI.

According to the embodiment of the disclosure, the first indication information and the second indication information are borne in the CSI, so that the first indication information and the second indication information can be reported at the same time when the CSI is reported, and the signaling consumption is reduced.

In a method for reporting channel state information provided by an embodiment of the present disclosure, CSI includes: first information and second information.

Wherein the first information corresponds to an indication domain of a fixed size, and the second information corresponds to the indication domain, the size of which is determined based on the first information; the first indication information and/or the second indication information is carried in the first information.

In an exemplary embodiment, the CSI may include two parts, namely part (part) 1 and part 2. Wherein, part 1 may correspond to the first information, and part 2 may correspond to the second information.

In another exemplary embodiment, the size of the indication field corresponding to the first information may be a fixed value. For example, a default size set in advance or specified by a protocol.

In another exemplary embodiment, the size of part 2 of the CSI is determined based on the information in part 1. Where the size of part 2 represents the size of the number of bits (bits) occupied by part 2 of the CSI. Such as 8 bits or 16 bits.

For example, the size of part 2 of the CSI is determined based on the first indication information in part 1. If the first indication information in part 1 indicates more target CSI-RS resources, the size of part 2 will be larger. Conversely, if the target CSI-RS resources indicated by the first indication information in part 1 are less, the size of part 2 is smaller.

For another example, the size of part 2 of the CSI is determined based on the second indication information in part 1. If the number of space base vectors corresponding to the target CSI-RS resource indicated by the second indication information in part 1 is greater, the size of part 2 will be greater. Otherwise, if the number of space base vectors corresponding to the target CSI-RS resource indicated by the first indication information in part 1 is smaller, the size of part 2 is smaller.

In the embodiment of the disclosure, when the number of the combined indexes required to be indicated by the second indication information is small, the signaling overhead of CSI reporting can be reduced.

In an exemplary embodiment, the first information includes non-zero coefficient position indication information.

It is understood that the non-zero coefficient position indication information may indicate the position of a coefficient where the coherence coefficient is non-zero.

In an exemplary embodiment, the first information includes a mode indication.

For example, the mode indication may be used to indicate CSI feedback mode, codebook mode, etc. CSI feedback modes may include mode 1, which is single TRP based feedback, and mode 2, which is multiple TRP based feedback. Of course, the CSI feedback mode may also include other modes, and the present disclosure is not limited. Codebook patterns may include codebook structure 1 and codebook structure 2, where codebook structure 1 feeds back a part of frequency domain basis vector (frequency domain basis, FD basis) information for all CSI-RS resources included in one CMR; the codebook structure 2 feeds back a part of frequency domain base vector information for each CSI-RS resource included in one CMR. The codebook pattern may also include other patterns, and the present disclosure is not limited.

Wherein the PMI information includes at least one of: spatial domain base vector parameter information; frequency domain base vector parameter information; non-zero coefficient position indication information; phase coefficient information; amplitude coefficient information.

In the embodiments of the present disclosure, the first configuration message and the second configuration message may be carried in different signaling or the same signaling, which is not limited by the embodiments of the present disclosure.
