[0040] The embodiments of the present disclosure provide a communication method, a terminal, a network device, a communication system, a storage medium, and a computer program product.

[0041] In a first aspect, an embodiment of the present disclosure proposes a communication method, which is executed by a terminal, and the method includes: sending a first message to a network device, wherein the first message includes channel state information CSI obtained by measuring at least one channel state information reference signal CSI-RS resource.

[0042] In the above embodiment, the terminal reports the CSI report of one or more CSI-RS resources through one first message, which can improve the CSI reporting efficiency.

[0043] In combination with some embodiments of the first aspect, in some embodiments, the first message includes multiple information contents, and the multiple information contents are obtained by preprocessing and dividing the CSI of each CSI-RS resource, wherein the multiple information contents are sorted in a preset order in the first message.

[0044] In the above embodiment, by sorting the multiple information contents in the first message according to a preset order, a certain system performance can be guaranteed when part of the CSI content is discarded (when part of the CSI content is lost).

[0045] In conjunction with some embodiments of the first aspect, in some embodiments, the preprocessing includes at least one of the following processes:

[0046] A first processing is used to combine first reported quantities with the same measurement value in the CSI of each of the CSI-RS resources;

[0047] The second processing is used to perform differential processing on the second reported amounts with different measurement values ​​in the CSI of each of the CSI-RS resources.

[0048] In the above embodiment, the data volume of the first message can be reduced through preprocessing, thereby improving the message transmission performance.

[0049] In combination with some embodiments of the first aspect, in some embodiments, the CSI of one CSI-RS resource includes first information content and second information content, and the multiple information contents include the first information content and the second information content.

[0050] In the above embodiment, by dividing the CSI of each CSI-RS resource into two parts, multiple information contents included in the first message can be obtained, which facilitates sorting of the multiple information contents.

[0051] In combination with some embodiments of the first aspect, in some embodiments, the first message includes a first part of CSI and a second part of CSI, and the priority of the first part of CSI is higher than the priority of the second part of CSI.

[0052] In some embodiments, the first portion of CSI includes a portion of the plurality of information contents, and the second portion of CSI includes another portion of the plurality of information contents.

[0053] In the above embodiment, by dividing the multiple information contents in the first message into two parts and sorting them separately, for example, sorting the first part of CSI and the second part of CSI in parallel, the efficiency of sorting can be improved.

[0054] In combination with some embodiments of the first aspect, in some embodiments, the first part of CSI includes the first information content in the CSI of the first CSI-RS resource, the first CSI-RS resource is the first CSI-RS resource in a resource sequence, and the resource sequence is obtained by sorting each of the CSI-RS resources according to the first metric value; the second part of CSI includes the second information content in the CSI of the first CSI-RS resource and the CSI of the remaining CSI-RS resources except the first CSI-RS resource.

[0055] In the above embodiment, by using the first information content in the CSI of the first CSI-RS resource as the first part of CSI alone, and using the second information content in the CSI of the first CSI-RS resource and the CSI of the remaining CSI-RS resources except the first CSI-RS resource as the second part of CSI, the first part of CSI and the second part of CSI can be sorted in parallel, thereby improving the sorting efficiency.

[0056] In combination with some embodiments of the first aspect, in some embodiments, the arrangement order between the information contents in the second part of the CSI is determined in the following manner: sorting the CSI of each CSI-RS resource according to the first metric value; sorting the first information content and the second information content of the CSI belonging to the same CSI-RS resource.

[0057] In the above embodiment, by sorting the CSI of each CSI-RS resource according to the first metric value and sorting the first information content and the second information content of the CSI belonging to the same CSI-RS resource, an ordered second part of CSI can be quickly obtained.

[0058] In combination with some embodiments of the first aspect, in some embodiments, the first part of CSI includes the first information content in the CSI of each of the CSI-RS resources; the second part of CSI includes the second information content in the CSI of each of the CSI-RS resources.

[0059] In the above embodiment, the first information content in the CSI of each CSI-RS resource is used as the first part of CSI, and the second information content in the CSI of each CSI-RS resource is used as the second part of CSI. This makes it easier to sort the first part of CSI because the granularity of each information content in the first part of CSI is the same. Similarly, because the granularity of each information content in the second part of CSI is also the same, it is also easier to sort the second part of CSI. Therefore, this information content division method can reduce the difficulty of sorting and help improve sorting efficiency.

[0060] In combination with some embodiments of the first aspect, in some embodiments, the arrangement order between each first information content in the first part of the CSI is determined in the following manner: sorting the first information content in the CSI of each CSI-RS resource according to the first metric value.

[0061] In the above embodiment, the first information content in the CSI of each CSI-RS resource may be sorted according to the first metric value, so as to quickly obtain the sorted first part of CSI.

[0062] In combination with some embodiments of the first aspect, in some embodiments, at least one measurement value indication information in at least one first information content is used to be shared with at least one other first information content.

[0063] In the above embodiment, by sharing some measurement value indication information among the first information contents, the data volume of the first part of CSI can be reduced and the data transmission performance can be improved.

[0064] In combination with some embodiments of the first aspect, in some embodiments, the arrangement order between each second information content in the second part CSI is determined in the following manner: the second information content in the CSI of each CSI-RS resource is sorted according to the first metric value.

[0065] In the above embodiment, the second information content in the CSI of each CSI-RS resource may be sorted according to the first metric value, so as to quickly obtain the sorted second part of CSI.

[0066] In combination with some embodiments of the first aspect, in some embodiments, at least one measurement value indication information in at least one second information content is used to be shared with at least one other second information content.

[0067] In the above embodiment, by sharing some measurement value indication information among the second information contents, the data volume of the second part of CSI can be reduced and the data transmission performance can be improved.

[0068] In combination with some embodiments of the first aspect, in some embodiments, a second information content includes N groups of information, where N is a natural number greater than 1; after sorting the first information content and the second information content of the CSI belonging to the same CSI-RS resource, it also includes: sorting the N groups of information belonging to the same second information content.

[0069] In the above embodiment, one or more second information contents may be further divided based on requirements (such as encoding requirements of the terminal, decoding requirements of the network device, etc.) to obtain N groups of information with smaller granularity, and the N groups of information may also be sorted.

[0070] In conjunction with some embodiments of the first aspect, in some embodiments, the second information content includes N groups of information, where N is a natural number greater than 1;

[0071] The method further includes: sorting information of the same group number in all the N groups of information according to the first metric value to obtain a sorting sequence corresponding to each group number; and sorting the sorting sequence corresponding to each group number to obtain the sorted second part of CSI.

[0072] In the above embodiment, by arranging information with the same group number together, a certain system performance can be guaranteed when part of the CSI content is lost. For example, it is easier for the network device to locate the lost smaller-granular content and then request the terminal to retransmit the lost part of the content.

[0073] In combination with some embodiments of the first aspect, in some embodiments, the nth group of information in each of the N groups of information includes multiple group information, and the value range of n is 1 to N. The method also includes: sorting multiple group information belonging to the same nth group of information.

[0074] In the above embodiment, the embodiment of the present disclosure may further divide each n-th group of information into a plurality of small group information for sorting.

[0075] In combination with some embodiments of the first aspect, in some embodiments, the first metric value is specified by a protocol or configured by a network device.

[0194] FIG1 is a schematic diagram illustrating an architecture of a communication system according to an embodiment of the present disclosure. As shown in FIG1 , the communication system 100 may include a terminal 101 and a network device 102 .

[0201] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0205] In some embodiments, for CSI reporting, the gNB configures the UE with the required CSI reporting amount through signaling. The CSI reporting amount includes at least one or more of CRI, LI, RI, CQI, and / or PMI. In related technologies, CSI feedback based on Type I or Type II codebooks divides the CSI reporting amount into two parts: Part 1 and Part 2. CSI reporting based on the Rel-15 Type I single-panel codebook includes Part 1 and Part 2. Part 1 includes at least one or more of RI, CRI, and CQI of the first codeword, while Part 2 includes at least one or more of PMI, LI, and CQI of the second codeword. PMI includes two types of information: i1 and i2, where i1 and i2 are wideband and subband feedback information, respectively.

[0206] In some embodiments, conventional CSI reporting based on the Rel-16 eType II codebook also includes Part 1 and Part 2. Part 1 includes at least one or more of RI, CQI, and non-zero coefficient indications for all layers, while Part 2 includes PMI information, which can be further divided into Group 0, Group 1, and Group 2.

[0207] In some embodiments, increasing the number of antenna ports to expand the antenna scale is a key technical approach to further improve system efficiency or enhance coverage. In current commercial deployments, the antenna scale can be quadrupled. For example, support for 64 or 128 CSI-RS ports is required to enable channel measurement for these 64 or 128 antenna ports. Considering the trade-off between performance and deployment cost, hybrid digital and analog beamforming will continue to be used in future standard evolution. With a larger number of ports, the number of users connected to the network also increases. Consequently, the network requires terminals to provide more CRI, LI, RI, CQI, and / or PMI feedback for multi-user scheduling and improved system performance. The CRI / LI / RI / CQI / PMI in each CSI report is calculated based on an independent CSI-RS resource, and the corresponding CSI-RS resource is indicated by the CRI. The CSI measured by the UE based on the resource indicated by the CRI can be reported using the traditional Rel-15 Type I single-panel codebook or the Rel-16 eType II codebook. As can be seen above, CSI reporting based on the Rel-15 Type I single-panel codebook or the Rel-16 eType II codebook is divided into two parts: Part 1 and Part 2. Therefore, when the CRI is greater than 1, multiple Part 1 and Part 2 contents must be reported. If these CSI contents are reported through a single CSI, then multiple Part 1 and Part 2 contents must be stored in a single CSI report. If partial CSI is discarded, different storage methods will affect system performance. How to store these CSI contents and ensure sufficient system performance even when partial CSI is discarded remains an unresolved issue.

[0208] In view of this, the embodiments of the present disclosure propose a communication method, terminal, network device, communication system, storage medium and computer program product, which store multiple Part 1 and Part 2 content methods in one CSI report, thereby ensuring that a certain system performance can still be maintained when part of the CSI is discarded.

[0209] FIG2A is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0210] In step S201 , the terminal 101 measures one or more CSI-RS resources to obtain the CSI corresponding to each CSI-RS resource.

[0211] The CSI corresponding to each CSI-RS resource may be referred to as a CSI report.

[0212] In some embodiments, the network device may indicate one or more CSI-RS resources that the terminal needs to measure, or the terminal may autonomously determine one or more CSI-RS resources that need to be measured. The CSI-RS resources that the terminal needs to measure may be referred to as CSI-RS resources to be measured.

[0213] In some embodiments, one CSI corresponding to one CSI-RS resource may include measurement results of at least one of the following reported quantities:

[0214] CRI;

[0215] RI;

[0216] CQI of the first codeword;

[0217] LI;

[0218] Non-zero coefficient number indication information of all layers;

[0219] PMI, PMI includes i1 and i2;

[0220] CQI of the second codeword.

[0221] In some embodiments, the measurement result may be a measurement value or indication information for indicating the measurement value, wherein the indication information for indicating the measurement value may be referred to as measurement value indication information.

[0222] In step S202 , the terminal 101 processes the CSI of all CSI-RS resources to obtain multiple information contents.

[0223] Here, all CSI-RS resources refer to all CSI-RS resources measured in step S201.

[0224] In some embodiments, a terminal processes the CSI of all CSI-RS resources to obtain multiple information contents. The implementation method may be: the CSI of all CSI-RS resources is divided and processed to obtain multiple information contents. Optionally, there is no duplication between the various information contents. Optionally, the information granularity between the various information contents may be the same or different. Optionally, any one of the information contents includes measurement value indication information corresponding to at least one of the following reported quantities in the CSI of at least one CSI-RS resource:

[0225] CRI;

[0226] RI;

[0227] CQI of the first codeword;

[0228] Non-zero coefficient number indication information;

[0229] i1;

[0230] i2;

[0231] CQI of the second codeword;

[0232] LI.

[0233] For example, an implementation method for dividing the CSI of all CSI-RS resources to obtain multiple information contents may be to divide the CSI of one CSI-RS resource into one information content. In this way, multiple information contents can be obtained by dividing the CSI of multiple CSI-RS resources, where one information content corresponds to one CSI-RS resource.

[0234] For example, an implementation method for dividing the CSI of all CSI-RS resources to obtain multiple information contents may be: dividing the CSI of each CSI-RS resource into a first information content and a second information content, thereby obtaining multiple information contents. The multiple information contents include the first information content and the second information content included in the CSI of each CSI-RS resource. For example, the first information content corresponding to a certain CSI-RS resource is one information content, the second information content corresponding to the certain CSI-RS resource is one information content, the first information content corresponding to another CSI-RS resource is one information content, and the second information content corresponding to the other CSI-RS resource is one information content.

[0235] In some embodiments, the first information content may be referred to as Part 1, and includes measurement value indication information corresponding to at least one of the following reported quantities:

[0236] CRI;

[0237] RI;

[0238] CQI of the first codeword;

[0239] Information indicating the number of non-zero coefficients.

[0240] In some embodiments, the second information content may be referred to as Part 2, and includes measurement value indication information corresponding to at least one of the following reported quantities:

[0241] PMI;

[0242] CQI of the second codeword;

[0243] LI.

[0244] For example, an implementation method for dividing the CSI of all CSI-RS resources to obtain multiple information contents may be: dividing the CSI of each CSI-RS resource into a first information content and a second information content, and further dividing each first information content to obtain N groups of information corresponding to each first information content (i.e., N groups of information). In this way, multiple information contents can be obtained. The multiple information contents include the second information content corresponding to each CSI-RS resource and the N groups of information corresponding to each first information content. For example, the second information content corresponding to a certain CSI-RS resource is one information content, and the N groups of information obtained by dividing the first information content corresponding to the certain CSI-RS resource are N information contents. For example, assume that a first information content is divided into two groups of information, wherein the reporting amount corresponding to the first group includes at least the CQI, i1, and LI information of the second codeword, and the reporting amount corresponding to the second group includes i2 information. Alternatively, the first group includes PMI information within odd subbands, and the second group includes PMI information within even subbands.

[0245] For example, the CSI of all CSI-RS resources may be divided and processed to obtain multiple information contents by: dividing the CSI of each CSI-RS resource into a first information content and a second information content, and further dividing each second information content to obtain N groups of information corresponding to each second information content (i.e., N groups of information). In this way, multiple information contents can be obtained. The multiple information contents include the first information content corresponding to each CSI-RS resource and the N groups of information corresponding to each second information content. For example, the first information content corresponding to a certain CSI-RS resource is one information content, and the N groups of information obtained by dividing the second information content corresponding to the certain CSI-RS resource are N information contents.

[0246] For example, the CSI of all CSI-RS resources may be divided and processed to obtain multiple information contents by: dividing the CSI of each CSI-RS resource into first information content and second information content, and further dividing each first information content to obtain N1 group information (i.e., N1 group information) corresponding to each first information content, and further dividing each second information content to obtain N2 group information (i.e., N2 group information) corresponding to each second information content. In this way, multiple information contents can be obtained.

[0247] For example, the CSI of all CSI-RS resources is divided and processed to obtain multiple information contents by dividing them, which can be implemented as follows: the CSI of each CSI-RS resource is divided into a first information content and a second information content, and further, each first information content is further divided to obtain N groups of information corresponding to each first information content (i.e., N group information). Optionally, each group information of the nth group number is further divided to obtain multiple small group information corresponding to each information of the nth group number. In this way, multiple information contents can be obtained. For example, the second information content corresponding to a certain CSI-RS resource is one information content, and the N-1 information contents that are not further divided into small groups in the N groups of information obtained by dividing the first information content corresponding to the certain CSI-RS resource are N-1 information contents, and the multiple small group information corresponding to the information of the nth group number that is further divided into small groups are multiple information contents.

[0248] In some embodiments, a terminal may process the CSI of all CSI-RS resources to obtain multiple information contents by preprocessing the CSI of all CSI-RS resources and dividing the information into multiple information contents. The order of preprocessing and dividing the information into multiple information contents is not limited. The implementation of the division processing can be found in the aforementioned embodiments and will not be further described here.

[0249] In some embodiments, pre-processing includes at least one of the following:

[0250] The first processing is used to combine the first reported quantities having the same measurement values ​​(or measurement results) in the CSI of each CSI-RS resource;

[0251] The second processing is used to perform differential processing on the second reported amounts having different measurement values ​​(or measurement results) in the CSI of each CSI-RS resource.

[0252] The following is an example of the first process. Assuming that the measured values ​​of the rank indication in the CSI of each CSI-RS resource are the same, the rank indication in the CSI of each CSI-RS resource is combined. In this case, the rank indication is the first reported amount. For example, the combined process includes: retaining only the measured value indication information of the rank indication of one CSI-RS resource (assuming it is called R1), and retaining the measured value indication information of the rank indication of the remaining CSI-RS resources (assuming it is called R1). 2～M ) shares (reuses) the measurement value indication information of the rank indication of R1. Wherein, M represents the total number of CSI-RS resources, M is an integer greater than or equal to 2, R 2～M Represents any one of the 2nd to Mth CSI-RS resources.

[0253] The second processing is described below with an example. Assuming that the measured values ​​of the CQI in the CSI of each CSI-RS resource are different, the CQI in the CSI of each CSI-RS resource can be differentially processed. In this case, the CQI is the second reported amount. For example, the differential processing includes: for one CSI-RS resource (assuming it is called R1), determining the measurement value indication information corresponding to the CQI of R1 according to the actual measured value of the CQI of R1; for the remaining CSI-RS resources (assuming it is called R1), determining the measurement value indication information corresponding to the CQI of R1 according to the actual measured value of the CQI of R1; 2～M ), according to R 2～M The difference between the actual measured value of the CQI of R1 and the actual measured value of the CQI of R2 determines the value of R 2～M The measurement value indication information corresponding to the CQI.

[0254] Optionally, R1 may refer to any one of all CSI-RS resources. For example, R1 may refer to the first CSI-RS resource after all CSI-RS resources are sorted.

[0255] In some embodiments, preprocessing may further include data preprocessing such as rounding up, normalization, and data conversion, which is not limited in this disclosure.

[0256] In step S203 , the terminal 101 divides the multiple information contents into a first part CSI and a second part CSI.

[0257] In some embodiments, the first message may be divided into two parts, for example, a first CSI part and a second CSI part. Since the first message includes multiple information contents, dividing the first message into the first CSI part and the second CSI part is equivalent to dividing the multiple information contents into the first CSI part and the second CSI part.

[0258] In some embodiments, if the first message includes a first portion of CSI and a second portion of CSI, the first portion of CSI may include a portion of information contents among a plurality of information contents, and the second portion of CSI may include another portion of information contents among the plurality of information contents.

[0259] For example, the first portion of CSI may include the first information content in the CSI of the first CSI-RS resource. Correspondingly, the second portion of CSI may include the second information content in the CSI of the first CSI-RS resource and the CSI of the remaining CSI-RS resources except the first CSI-RS resource.

[0260] In some embodiments, the first CSI-RS resource is the first CSI-RS resource in the resource sequence, or the first CSI-RS resource is the last CSI-RS resource in the resource sequence, or the first CSI-RS resource is the CSI-RS resource at the median in the resource sequence, or the first CSI-RS resource is the CSI-RS resource at the first even-numbered position in the resource sequence, or the first CSI-RS resource is the CSI-RS resource at the last even-numbered position in the resource sequence, and the present disclosure does not impose specific restrictions on this. The resource sequence is obtained by sorting each CSI-RS resource according to the first metric value. The sorting method includes but is not limited to sorting methods such as small to large, from large to small, odd numbers first and even numbers later, etc.

[0261] The first metric value is at least one of the following parameter items corresponding to the CSI-RS resource specified by the protocol or configured by the network device:

[0262] Identification, which is an ID and / or index;

[0263] Channel quality indication CQI;

[0264] Signal to Interference plus Noise Ratio (SINR);

[0265] Rank indication RI;

[0266] Precoding matrix indicator PMI;

[0267] Reference signal received power RSRP;

[0268] Reference Signal Received Quality RSRQ.

[0269] For example, the first part of CSI may include first information content in the CSI of each CSI-RS resource, and correspondingly, the second part of CSI may include second information content in the CSI of each CSI-RS resource.

[0270] In some embodiments, the first information content of the first CSI-RS resource in the first part of the CSI may further include a CSI-RS resource indication CRI.

[0271] In step S204, the terminal 101 sorts the information contents in the first part of the CSI and the second part of the CSI respectively.

[0272] It should be noted that the order of the sorting process and the pre-processing / division process in step S202 is not limited.

[0273] In some embodiments, if the division process in step S202 divides the CSI of each CSI-RS resource into a corresponding first information content and a second information content. Then, when the first part of the CSI includes the first information content in the CSI of the first CSI-RS resource, and the second part of the CSI includes the second information content in the CSI of the first CSI-RS resource and the CSI of the remaining CSI-RS resources except the first CSI-RS resource, the arrangement order between the information contents in the second part of the CSI can be determined as follows: sorting the CSI of each CSI-RS resource according to the first metric value; sorting the first information content and the second information content of the CSI belonging to the same CSI-RS resource. For example, assuming that the sorting priority of the first information content under the CSI of the same CSI-RS resource is higher than the sorting priority of the second information content, then when the sorting priority of the first part of the CSI is higher than the sorting priority of the second part of the CSI, the sorting result shown in Figure 2B can be obtained.

[0274] It should be noted that the sorting priority of the first information content under the CSI of the same CSI-RS resource may also be lower than the sorting priority of the second information content.

[0275] In some embodiments, if the partitioning process in step S202 partitions the CSI of each CSI-RS resource into a corresponding first information content and a second information content, and further partitions each second information content into N groups of information, then, if the first portion of CSI includes the first information content in the CSI of the first CSI-RS resource, and the second portion of CSI includes the second information content in the CSI of the first CSI-RS resource and the CSI of CSI-RS resources other than the first CSI-RS resource, the order of the information contents in the second portion of CSI can be determined as follows: sorting the CSI of each CSI-RS resource according to the first metric; sorting the first information content and the second information content of the CSI belonging to the same CSI-RS resource; and sorting the N groups of information belonging to the same second information content, where N is a natural number greater than 1. For example, assuming that the sorting priority of the first information content in the CSI of the same CSI-RS resource is higher than the sorting priority of the second information content, assuming N is 2, and assuming that the sorting priority of the first group of information for the same second information content is higher than the sorting priority of the second group, then the sorting result shown in FIG2C can be obtained.

[0276] It should be noted that, when N is 2, the sorting priority of the first group of information under the same second information content may also be lower than the sorting priority of the second group.

[0277] In some embodiments, if the division process in step S202 divides the CSI of each CSI-RS resource into a corresponding first information content and a second information content, then when the first part of the CSI includes the first information content in the CSI of each CSI-RS resource, and the second part of the CSI includes the second information content in the CSI of each CSI-RS resource, the arrangement order between the first information contents in the first part of the CSI can be determined by sorting the first information content in the CSI of each CSI-RS resource according to the first metric value. It should be noted that since the CSI of all CSI-RS resources can be pre-processed in step S202, in some scenarios, at least one measurement value indication information in at least one first information content can be used to share with at least one other first information content. Furthermore, the arrangement order between the second information contents in the second part of the CSI can be determined by sorting the second information content in the CSI of each CSI-RS resource according to the first metric value. It should be noted that, since the CSI of all CSI-RS resources can be pre-processed in step S202, in some scenarios, at least one measurement value indication information in at least one second information content can be used in conjunction with at least one other second information content. For example, assuming that the sorting priority of the first group of information under the same second information content is higher than the sorting priority of the second group, the sorting result shown in FIG2D can be obtained.

[0278] In some embodiments, if the partitioning process in step S202 partitions the CSI of each CSI-RS resource into a corresponding first information content and a second information content, and further partitions each second information content into N groups of information, where N is a natural number greater than 1, then, if the first portion of CSI includes the first information content in the CSI of each CSI-RS resource, and the second portion of CSI includes the second information content in the CSI of each CSI-RS resource, the order of arrangement between the first information contents in the first portion of CSI can be determined as follows: sorting the first information content in the CSI of each CSI-RS resource according to the first metric value. Furthermore, the order of arrangement between the information contents in the second portion of CSI can be determined as follows: sorting the information with the same group number in all N groups of information according to the first metric value to obtain a sorted sequence corresponding to each group number; and sorting the sorted sequence corresponding to each group number to obtain a sorted second portion of CSI. For example, assuming that the sorting priority of the first group of information under the same second information content is higher than the sorting priority of the second group, the sorting result shown in FIG2E can be obtained.

[0279] In some embodiments, if the division process in step S202 divides the CSI of each CSI-RS resource into a corresponding first information content and a second information content, and further divides each second information content into N groups of information, where N is a natural number greater than 1, and further, each n-th group of information in the N groups of information corresponding to each second information is divided into multiple small group information, then, when the first part of the CSI includes the first information content in the CSI of each CSI-RS resource, and the second part of the CSI includes the second information content in the CSI of each CSI-RS resource, the arrangement order between the first information contents in the first part of the CSI can be determined as follows: sorting the first information content in the CSI of each CSI-RS resource according to the first metric value. Furthermore, the arrangement order between the information contents in the second part of the CSI can be determined as follows: sorting the information with the same group number in all N groups of information according to the first metric value to obtain a sorted sequence corresponding to each group number; sorting the sorted sequence corresponding to each group number; and sorting the multiple small group information belonging to the same n-th group of information to obtain a sorted second part of the CSI. For example, if n is 2 and it is assumed that the sorting priority of the first group of information under the same second information content is higher than the sorting priority of the second group, then the sorting result shown in FIG. 2F can be obtained.

[0280] The following is an example of an embodiment in which each n-th group of information in N groups of information corresponding to each second information is divided into multiple small group information. Assume that N is 3 and n is 2, and assume that there is a first CSI-RS resource and a second CSI-RS resource. Assume that the second information corresponding to the first CSI-RS resource is divided into 3 groups, for example, G 1,1 , G 1,2 , G 1,3 , assuming that the second information corresponding to the second CSI-RS resource is divided into 3 groups, for example, G 2,1 , G 2,2 , G 2,3 Then, for the first three groups of information, namely G 1,1 , G 1,2 , G 1,3 , the second set of information, namely G 1,2 Divide into multiple groups of information. For the second three groups of information, namely G 2,1 , G 2,2 , G 2,3 , the second set of information, namely G 2,2 Divide information into multiple groups.

[0281] Step S205: The terminal 101 obtains a first message according to the sorted first part of the CSI and the second part of the CSI.

[0282] In some embodiments, the first message is obtained according to a ranking priority between the first portion of CSI and the second portion of CSI.

[0283] Optionally, the sorting priority of the first part of CSI is higher than the sorting priority of the second part of CSI.

[0284] Optionally, the sorting priority of the first part of CSI is lower than the sorting priority of the second part of CSI.

[0285] In some embodiments, the first message is used to report channel state information CSI of at least one CSI-RS resource to the network device.

[0286] In some embodiments, the first message is used to report channel state information CSI of multiple CSI-RS resources to the network device.

[0287] In some embodiments, the name of the first message is not limited, and it can be, for example, a multiple CSI report, a specific CSI report, etc.

[0288] In some embodiments, steps S203 to S205 can be replaced by sorting the multiple information contents obtained in step S202 to obtain a first message. For example, the multiple information contents obtained in step S202 are sorted according to a preset order to obtain the first message. That is, the multiple information contents are sorted according to a preset order in the first message. The preset order can be an arrangement order determined according to any rule. The sorting result can be the sorting results shown in Figures 2B to 2F.

[0289] Step S206 : Terminal 101 sends a first message to network device 102 .

[0290] In some embodiments, the implementation of the terminal sending the first message to the network device may include: independently encoding each information content, and sending the ordered independent encoding results to the network device at one time.

[0291] In some embodiments, the terminal sending the first message to the network device may include independently encoding the first portion of CSI and the second portion of CSI. Optionally, each piece of information in the first portion of CSI is independently encoded. Optionally, each piece of information in the second portion of CSI is independently encoded. Optionally, the terminal sending a coded sequence including the results of each independent encoding to the network device.

[0292] In some embodiments, the terminal may send each independent encoding result to the network device in sequence.

[0293] Step S207: The network device 102 decodes the first message.

[0294] In some embodiments, the name of the decoding process is not limited, and it can be, for example, a decompression process, a decryption process, a parsing process, etc.

[0295] In some embodiments, the network device sequentially decodes each independent code in the code sequence according to the code granularity.

[0296] For example, the network device first decodes the encoding result of the first part of the CSI, and then decodes the encoding result of the second part of the CSI.

[0297] For example, the network device first sequentially decodes the encoding results of each information content in the first part of the CSI, and then sequentially decodes the encoding results of each information content in the second part of the CSI.

[0298] For example, the network device first decodes the encoding result of the first part of the CSI, and then sequentially decodes the encoding results of each information content in the second part of the CSI.

[0370] Figure 5 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 5, the embodiment of the present disclosure relates to a communication method, which includes:

[0375] The communication method involved in the embodiment of the present disclosure may include at least one of steps S501 and S502. For example, step S501 may be implemented as an independent embodiment, and step S502 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0376] In some embodiments, step S501 and step S502 may be performed in an interchangeable order or simultaneously.

[0377] In some embodiments, one or more of step S501 and step S502 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0378] In some embodiments, the above method may also include the processing steps described in the above embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.

[0379] In some embodiments, the terminal reports the CSI reporting amount corresponding to M (M is greater than or equal to 1) CSI-RS resources. The CSI reporting amount corresponding to each CSI-RS resource includes Part 1 and Part 2, where Part 1 includes at least one or more of CRI, RI, CQI of the first codeword, and non-zero coefficient number indication information; Part 2 includes at least one or more of PMI, CQI of the second codeword, and LI information.

[0380] In some embodiments, the CSI reporting amount corresponding to the M CSI-RS resources is divided into a first CSI part and a second CSI part, wherein the first CSI part corresponds to the first part of CSI in the above embodiment, and the second CSI part corresponds to the second part of CSI in the above embodiment.

[0381] In some embodiments, Example 1, M CSI reporting amounts are divided into a first CSI part and a second CSI part for reporting, the first CSI part includes the CSI reporting amount included in Part 1 of the CSI reporting amount corresponding to the first CSI-RS resource, the second CSI part includes the CSI reporting amount included in Part 2 of the CSI reporting amount corresponding to the first CSI-RS resource, and the CSI reporting amounts corresponding to other M-1 CSI-RS resources.

[0382] Optionally, the first CSI-RS resource is determined according to a first metric value, or according to a configured CSI-RS resource index or an order of CSI-RS resource IDs.

[0383] Optionally, the first metric is predefined by a protocol or configured by a network, or the first metric value is determined by at least one of CQI, SINR, RI, and PMI of the CSI-RS resource.

[0384] Optionally, the priority of the CSI reporting amount corresponding to each CSI-RS resource is determined according to the order of the first metric value or the CSI-RS resource index or the CSI-RS resource ID, and the priority of Part 1 of the CSI reporting amount corresponding to each CSI-RS resource is higher than Part 2.

[0385] For example, assume that the UE reports the CSI reported amounts corresponding to M = 2 CSI-RS resources, and the CSI reported for each resource uses the Rel-15 Type I single-panel codebook method. The CSI reported for each resource still uses the traditional Part 1 and Part 2 reporting, where Part 1 includes RI, CQI, and CRI, and CRI can include the CSI reported amount corresponding to each CSI-RS resource or the CSI reported amount corresponding to the first CSI-RS resource. If the value of M is reported by the UE, then the indication of the value of M is also included in the CSI reported amount corresponding to the first CSI-RS resource.

[0386] Furthermore, it is assumed that the first CSI-RS resource is determined according to the first metric value, and it is assumed that the first metric value is the value of the CQI corresponding to the first codeword. It is assumed that the CQI corresponding to the first codeword of the CSI report indicated by the first CSI-RS resource among the M resources is the largest. The CSI reporting amount corresponding to the M=2 resources is divided into the first CSI part and the second CSI part reporting. The first CSI part includes the CSI reporting amount included in Part 1 of the CSI reporting amount corresponding to the first CSI-RS resource, and the second CSI part includes the CSI reporting amount included in Part 2 of the CSI reporting amount corresponding to the first CSI-RS resource, as well as the CSI reporting amounts corresponding to the other M-1 CSI-RS resources. As shown in Figure 6A, each CRI in Figure 6A refers to each CSI-RS resource, and the priority of the reporting amount corresponding to each CRI is from high to low from left to right. The priority of the first CSI part is higher than that of the second CSI part. For the second CSI part, the priority of Part 2 corresponding to the first CRI (i.e., the first CSI-RS resource) is higher than the CSI reporting amount corresponding to the second CRI (i.e., the second CSI-RS resource). The priority of Part 1 in the second CRI is higher than Part 1 in the second CRI.

[0387] In some embodiments, Example 2, the M CSI reporting amounts are divided into a first CSI part and a second CSI part, the first CSI part includes the CSI reporting amounts included in Part 1 of the CSI reporting amounts corresponding to all CSI-RS resources, and the second CSI part includes the CSI reporting amounts included in Part 2 of the CSI reporting amounts corresponding to all CSI-RS resources. The priority of the first CSI part is higher than the priority of the second CSI part. The priority of Part 1 corresponding to each resource included in the first CSI part is determined according to the order of the first metric value or the CSI-RS resource index or the CSI-RS resource ID; the priority of Part 2 corresponding to each resource included in the second CSI part is also determined according to the order of the first metric value or the CSI-RS resource index or the CSI-RS resource ID.

[0388] For example, assuming the same conditions as those described in the example of Example 1, FIG6B illustrates the storage of reported quantities corresponding to two CRIs according to the method described in Example 2. In FIG6B , because the CQI corresponding to the first codeword of the CSI report indicated by the first CRI is the largest, Part 1 corresponding to the first CRI included in the first CSI part has a higher priority than Part 1 corresponding to the second CRI. Similarly, Part 2 corresponding to the first CRI included in the second CSI part has a higher priority than Part 2 corresponding to the second CRI.

[0389] In some embodiments, embodiment 3, for Type I CB, the reporting amount included in Part 2 of the CSI reporting amount corresponding to each CSI-RS resource described in embodiment 1 or embodiment 2 is divided into two groups.

[0390] Optionally, the order of storing the CSI reporting amounts contained in Part1 corresponding to each resource is the same as in Example 1 or Example 2. For Part2, the CSI reporting amounts contained in the first group of Part2 in the M CSI reporting amounts are first stored in sequence, and then the CSI reporting amounts contained in the second group of Part2 in the M CSI reporting amounts are stored in sequence. The priority of the first CSI part is higher than the priority of the second CSI part. When the first CSI part contains multiple Part1s, the priority of Part1 corresponding to each resource contained in the first CSI part is determined according to the order of the first metric value or CSI-RS resource index or CSI-RS resource ID; the first group priority of Part2 corresponding to each resource contained in the second CSI part is higher than the second group priority, and when the first group or second group contains CSI reporting amounts corresponding to multiple CSI-RS resources, the first group or second group priority corresponding to each resource is determined according to the order of the first metric value or CSI-RS resource index or CSI-RS resource ID.

[0391] For example, the assumptions are the same as those described in the example under Example 1. However, the CSI reporting amount contained in Part 2 is divided into two groups. For example, the first group contains at least the CQI, i1, and LI information of the second codeword, and the second group contains the i2 information. Alternatively, the first group contains the PMI information in the odd subband, and the second group contains the PMI information in the even subband. The storage order of the two Parts 1 and two Parts 2 corresponding to the two CRIs shown in Figure 6C is divided into two groups. Note that Figure 6C only exemplifies the first CSI part containing the contents of M Parts 1. Optionally, it can also only contain the contents of Part 1 corresponding to the first CSI-RS resource, as described in the example under Example 1. The CSI priority in Figure 6C is defined as corresponding to high priority to low priority from left to right, that is, the priority of the first CSI part is higher than the priority of the second CSI part. When the first CSI part contains the priority of Part 1 as described in the example under Example 2, the first group priority of Part 2 corresponding to each resource contained in the second CSI part is higher than the second group priority, and the first group priority corresponding to the first CRI is higher than the first group priority corresponding to the second CRI. Similarly, the second group corresponding to the first CRI has a higher priority than the second group corresponding to the second CRI.

[0392] In some embodiments, in Example 4, each CSI Part 2 is divided into three groups. Optionally, the method for storing the M CSI reported quantities is the same as described in Example 3. Regarding priority, the priority of the CSI reported quantities included in the first CSI part is the same as described in Example 3, while the second group priority of Part 2 corresponding to each resource included in the second CSI part is higher than the third group priority. The third group priority is determined based on the order of the first metric value, CSI-RS resource index, or CSI-RS resource ID.

[0393] For example, the assumption is the same as that in Example 3, except that Part 2 corresponding to each resource is divided into three groups. Correspondingly, the CSI reporting amount corresponding to each resource is shown in FIG6D .

[0394] In some embodiments, Example 5, the order of storing Part 1 of the M CSI reporting amounts is the same as that of Example 3, and for the Part 2 of the M CSI reporting amounts, the CSI reporting amounts contained in the first group of the M CSI Part 2 are first stored in sequence, and then the CSI reporting amounts contained in the second group and the third group of each CSI reporting amount Part 2 are stored in sequence. Regarding priority, the priority of the CSI reporting amounts contained in the first CSI part is the same as that described in Example 3, and the priority of the first group in the second CSI part Part 2 is determined according to the order of the first metric value or the CSI-RS resource index or the CSI-RS resource ID, and the priority of the first group of Part 2 is higher than that of the second and third groups. The priority of the second and third groups in Part 2 is determined according to the order of the first metric value or the CSI-RS resource index or the CSI-RS resource ID, and the priority of the second group corresponding to each CSI-RS resource is higher than that of the third group.

[0395] For example, it is assumed that the conditions are the same as those in Example 3, and the Part2 corresponding to each resource is also divided into three groups, but the first group corresponding to each resource is stored first, and then the second and third groups corresponding to the first CRI are stored. Finally, the second and third groups corresponding to the second CRI are stored. As shown in Figure 6E, the three groups are stored in the two Part1s and two Part2s corresponding to the two CRIs. The priority of the first CSI part in Figure 6E is as described above, and the priority of the first group of the second CSI part is higher than the priority of the second and third groups. According to the priority definition method of the CSI reporting amount corresponding to the aforementioned CSI-RS resource, it can be seen that the priority of the second and third groups corresponding to the first CRI is higher than the second and third groups corresponding to the second CRI. For the CSI reporting amount corresponding to each CRI, the priority of the second group is higher than the priority of the third group.

[0396] In some embodiments, Example 6 reports the CSI reporting amounts corresponding to the M CSI-RS resources in a certain order, such as according to the CSI-RS resources, or in the order determined by the above-mentioned first metric value, that is, the storage order of the CSI reporting amounts corresponding to the M CSI-RS resources is the same as that of Examples 1 to 5, except that the CSI reporting amounts corresponding to the M CSI-RS resources are not further divided into the first CSI part and the second CSI part.

[0397] Optionally, Part 1 corresponding to the first CSI-RS resource in the first CSI part may further include an indication of the number of CRIs.

[0398] Optionally, the reporting amount corresponding to each CSI-RS resource is not distinguished between Part 1 and Part 2, but is reported as a whole. Then, the above-mentioned embodiments 1 to 5 are equivalently regarded as not including the second CSI part, and embodiment 6 can be equivalently regarded as not having the Part 2 part.

[0399] Optionally, the CSI reported amounts included in Part 1 corresponding to each resource are merged together without distinguishing which resource corresponds to Part 1. Alternatively, the CSI reported amounts included in Part 2 corresponding to each resource are merged together without distinguishing which resource corresponds to Part 2.

[0400] Optionally, the first CSI part and the second CSI part may be independently encoded respectively, and / or Part 1 and Part 2 of each CSI reporting amount may be independently encoded.

[0401] For example, assuming the same conditions as in Examples 1 to 5, and the storage method for M = 2 CSI reported amounts is the same as in Examples 1 to 5. The difference is that the CSI is no longer divided into the first and second CSI parts. Taking Example 1 as an example, Figure 6F illustrates a storage order similar to that of Example 1, but without further dividing the CSI reported amounts corresponding to the M CSI-RS resources into the first and second CSI parts. The priority definition is the same as that described in Examples 1 to 5.
