The communication interface 330 is used to support communication between the first electronic device and other devices. The Processor 310 may be, for example, a Central Processing Unit (CPU), a general purpose Processor, a Digital Signal Processor (DSP), an Application-Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other Programmable logic device, a transistor logic device, a hardware component, or any combination thereof.

In a specific implementation, the processor 310 is configured to perform any one of the steps performed by the terminal or the network device in the following method embodiments, and when performing data transmission such as sending, the communication interface 330 is optionally invoked to complete the corresponding operation.

It should be noted that the structural schematic diagram of the electronic device 300 is merely an example, and more or fewer devices may be specifically included, which is not limited herein.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a CSI report transmission method according to an embodiment of the present application, where the CSI report transmission method includes:

step 201, the terminal sends a CSI report to the network device.

In step 202, the network device receives a CSI report from the terminal.

Wherein the CSI report is associated with CSI measurements of an inactive bandwidth part, BWP, of a current serving cell.

In a specific implementation, the CSI report may be associated with CSI measurement of an inactive bandwidth part BWP of a current serving cell, or the CSI report may also be associated with CSI measurement of an active bandwidth part BWP of the current serving cell, or at least one of the CSI reports may be associated with CSI measurement of the inactive bandwidth part BWP of the current serving cell, or at least one of the CSI reports may be associated with CSI measurement of the active bandwidth part BWP of the current serving cell.

In the embodiment of the present application, the terminal sends the CSI report to the network device, where the CSI report is associated with CSI measurement of the inactive bandwidth portion BWP of the current serving cell, and as a result, the embodiment of the present application may also support CSI measurement and reporting on the inactive BWP, which is wider than that only supported CSI measurement and reporting on the active BWP, and may support CSI measurement and reporting on a non-terrestrial network, which is beneficial to improving flexibility of resource scheduling of the network device and improving network performance.

In one possible example, the priority of the CSI report is determined according to a first parameter set, the first parameter set including a first parameter for characterizing CSI measurements for active BWP or for non-active BWP.

In a specific implementation, when multiple CSI reports need to be reported on the same resource, and if the resource is limited in size and cannot carry multiple CSI reports, priorities of different CSI reports are used for a terminal to determine how to report corresponding CSI. The smaller the value of the priority, the higher the priority of the corresponding CSI report.

Each CSI report may be associated with a priority, and when determining the priority of the CSI, the priority may be determined according to a plurality of parameters, where the plurality of parameters may include a parameter for characterizing CSI measurement of the CSI report corresponding to an active BWP or an inactive BWP, that is, when determining the priority, the CSI report corresponding to the BWP may be considered as the active BWP or the inactive BWP.

In addition, the value of the priority can also consider cell index, CSI report content, CSI report type and CSI report ID, namely, the priority can be defined comprehensively according to the parameters for representing the contents.

It can be seen that, in this example, the priority of the CSI report is determined according to a first parameter group, where the first parameter group includes a first parameter for characterizing the CSI measurement of the CSI report corresponding to the active BWP, or the first parameter is for characterizing the CSI measurement of the CSI report corresponding to the inactive BWP, and the priority of the CSI report is determined according to the parameter group including the first parameter, which is beneficial to improve the comprehensiveness and comprehensiveness of the priority determination parameter.

In one possible example, the value of the first parameter is a first value when the CSI report corresponds to CSI measurement of an active BWP, and the value of the first parameter is a second value when the CSI report corresponds to CSI measurement of an inactive BWP.

In a specific implementation, when determining the priority of the CSI report, the first parameter may have two values, which correspond to a CSI measurement condition of an active BWP corresponding to the CSI report and a CSI measurement condition of an inactive BWP corresponding to the CSI report, respectively. Different values of the first parameter are used for representing different conditions, and the specific values of the first parameter and the second parameter are not limited here and can be set according to actual needs.

As can be seen, in this example, when the CSI report corresponds to CSI measurement of an active BWP, the value of the first parameter is a first value, and when the CSI report corresponds to CSI measurement of an inactive BWP, the value of the first parameter is a second value. Different conditions are represented by different specific values of the first parameter, so that the accuracy of priority determination is improved.

In one possible example, the first value is 1 and the second value is 0, or the first value is 0 and the second value is 1.

In a specific implementation, specific values of the first value and the second value may be determined as needed. For example, for a CSI report carrying CSI measurements of an active BWP, the value of the first parameter is 1; for a CSI report carrying CSI measurement of inactive BWP, the value of the first parameter is 0; or, for a CSI report carrying CSI measurement of active BWP, the value of the first parameter is 0; for a CSI report carrying CSI measurements for inactive BWP, the value of the first parameter is 1.

Specifically, the priority value Pri corresponding to each CSI report_iCSICan be determined by the following formula:

Pri_iCSI(y,k,c,s)＝2×N_cells×M_S×y+N_cells×M_S×k+M_S×c+M_S×l+s，

wherein, for an aperiodic CSI report scheduled to be carried on a Physical uplink control channel (PUSCH), a value of y is 0; for the CSI report which is scheduled and carried on the PUSCH and is subjected to semi-persistent scheduling, the value of y is 1; for a semi-persistent scheduled CSI report that is scheduled to be carried on a Physical Uplink Control Channel (PUCCH), the value of y is 2; for the periodic CSI report carried on the PUCCH in a scheduled mode, the value of y is 3;

for CSI reports carrying Layer 1Reference Signal Received Power (L1-RSRP) or Layer 1Signal to Interference plus Noise Ratio (L1-SINR), the value of k is 0; for the CSI report carrying non-L1-RSRP or L1-SINR, the value of k is 1;

c is the cell index value, N_cellsIs the value of the high-level parameter maxNrofServinCells;

l is a first parameter, and for a CSI report carrying CSI measurement of active BWP, the value of l is 1; for a CSI report carrying CSI measurement of inactive BWP, the value of l is 0; or, for the CSI report carrying the CSI measurement of the active BWP, the value of l is 0; for a CSI report carrying CSI measurement of inactive BWP, the value of l is 1;

s is reportConfigID, M_SIs the value of the high-level parameter maxNrofCSI-ReportConfigurations.

It can be seen that, in this example, the first value is 1, and the second value is 0, or the first value is 0 and the second value is 1, and different situations are represented by different specific values of the first parameter, which is beneficial to improving accuracy of priority determination.

In one possible example, before the network device receives the CSI report from the terminal, the method further includes: and the network equipment sends DCI to the terminal, wherein the DCI is used for indicating the terminal to carry out the CSI measurement, and the DCI is common DCI or user group DCI.

In this possible example, before the terminal sends the CSI report to the network device, the method further includes: the terminal receives downlink control information DCI from the network equipment, wherein the DCI is used for indicating the terminal to carry out CSI measurement, and the DCI is common DCI or user group DCI.

Generally, before sending a CSI report to a network device, a terminal receives DCI from the network device and performs CSI measurement according to DCI indication, and considering that current aperiodic CSI measurement and reporting only supports a case of triggering through unicast DCI, a unicast manner may bring excessive system overhead to the network device.

Therefore, the DCI received by the terminal from the network device may be common DCI or DCI of user groups, and one DCI may include configuration information of each terminal in at least one terminal in a user group, that is, the network device may trigger multiple users to perform aperiodic CSI measurement and report in a broadcast or multicast manner, which may reduce system overhead of the network device.

Wherein, the at least one terminal may be all terminals or part of terminals in all terminals included in the current user group.

For example, assuming that the user group a includes 5 terminals, namely, terminal 1, terminal 2, terminal 3, terminal 4, and terminal 5, the DCI may include configuration information of three terminals, namely, terminal 1, terminal 2, and terminal 3, that is, the network device may instruct terminal 1, terminal 2, and terminal 3 to perform CSI measurement through the DCI.

For another example, if the user group a includes 5 terminals, namely, terminal 1, terminal 2, terminal 3, terminal 4, and terminal 5, the DCI may include configuration information of all five terminals of the current user group, that is, the terminal 1, terminal 2, terminal 3, terminal 4, and terminal 5, that is, the network device may instruct terminal 1, terminal 2, terminal 3, terminal 4, and terminal 5 to perform CSI measurement through the DCI.

As can be seen, in this example, the DCI received by the terminal from the network device is a common DCI or a user group DCI, which is beneficial to reducing the system overhead of the network device.

In one possible example, the DCI includes at least one of: CSI request information and CSI feedback resource indication information.

In a specific implementation, the DCI is a common DCI or a user group DCI, and one DCI may include information corresponding to one terminal or each terminal in a plurality of terminals. For example, the DCI may include CSI request information and CSI feedback resource indication information of each terminal in at least one terminal in the user group. When receiving the DCI, the terminal can perform CSI measurement and report according to the CSI request information and the CSI feedback resource indication information which are contained in the DCI and correspond to the terminal. The CSI feedback resource indication information may be used to indicate a channel resource on which the terminal may report CSI. The DCI contains multiple groups of configuration information of multiple terminals, which is beneficial to reducing the system overhead.

As can be seen, in this example, the DCI may include CSI request information and/or CSI feedback resource indication information, which enables the network device to instruct the terminal to perform CSI measurement for inactive BWP.

In one possible example, the CSI feedback resource indication information includes at least one of: physical Uplink Control Channel (PUCCH) resource indication information and Physical Uplink Shared Channel (PUSCH) resource indication information.

In specific implementation, the CSI feedback resource indication information may be PUCCH resource indication information or PUSCH resource indication information, and the terminal may report CSI according to the PUCCH resource specifically indicated in the CSI feedback resource indication information or the PUSCH resource.

As can be seen, in this example, the CSI feedback resource indication information includes at least one of the following: the terminal can report the CSI according to the CSI feedback resource indication information, and the accuracy of CSI reporting resource allocation is improved.

In one possible example, the DCI includes at least one of: CSI request information, PUCCH resource indication information, and physical downlink shared channel hybrid automatic repeat request feedback timing indication information PDSCH-to-HARQ _ feedback timing indicator.

The PDSCH-to-HARQ _ feedback timing indicator may be used to indicate how long HARQ-ACK information needs to be sent after detecting or receiving the CSI-RS.

The specific DCI design may be as follows:

DCI content (DCI content):

[block 1,block 2,block 3,…],

block 1＝[CSI request,PUCCH resource indicator,PDSCH-to-HARQ_feedback timing indicator]

one piece of DCI comprises a plurality of blocks, each block corresponds to one user, namely one terminal, and the terminal can acquire the block corresponding to the terminal according to the high-level information. CSI request is CSI request information, and PUCCH resource indicator is PUCCH resource indication information.

block 1 is an exemplary block, the type of information included in any block in other blocks may be the same as block 1, different blocks correspond to different terminals, and the terminals may perform CSI measurement and report according to the information in the block corresponding to the terminal.

It can be seen that, in this example, the DCI includes at least one of the following information: CSI request information, PUCCH resource indication information, and physical downlink shared channel hybrid automatic repeat request feedback timing indication information PDSCH-to-HARQ _ feedback timing indicator. One DCI may include configuration information of each terminal in at least one terminal in a user group, which is advantageous for reducing system overhead of a network device.

In one possible example, the DCI includes at least one of: CSI request information, time domain resource allocation information, frequency domain resource allocation information, a frequency hopping flag, and a modulation and coding scheme.

The specific DCI design may be as follows:

DCI content:

[block 1,block 2,block 3,…],

block 1＝[CSI request,Time domain resource assignment，Frequency domain resource assignment，Frequency hopping flag，Modulation and coding scheme]

the CSI request is CSI request information, Time domain resource allocation information is Time domain resource allocation information, Frequency domain resource allocation information is Frequency domain resource allocation information, Frequency hopping flag is Frequency hopping flag, and Modulation and coding scheme is Modulation and coding scheme.

It can be seen that, in this example, the DCI includes at least one of the following information: CSI request information, time domain resource allocation information, frequency domain resource allocation information, a frequency hopping flag, and a modulation and coding scheme. One DCI may include configuration information of each terminal in at least one terminal in a user group, which is advantageous for reducing system overhead of a network device.

Referring to fig. 3, fig. 3 is a schematic flowchart of another CSI report transmission method according to an embodiment of the present application, where as shown in the figure, the CSI report transmission method includes the following steps:

step 301, the network device sends DCI to the terminal.

Step 302, the terminal receives DCI from the network device.

The DCI is used for indicating the terminal to perform CSI measurement, and the DCI is common DCI or user group DCI.

Therefore, the DCI received by the terminal from the network device may be common DCI or DCI of user groups, and one DCI may include configuration information of each terminal in at least one terminal in a user group, that is, the network device may trigger a plurality of user terminals to perform aperiodic CSI measurement and report in a broadcast or multicast manner, which may reduce system overhead of the network device.

In the embodiment of the application, a terminal receives DCI from network equipment, wherein the DCI is used for indicating the terminal to perform CSI measurement, and the DCI is common DCI or user group DCI. Therefore, the terminal receives the DCI from the network equipment as the public DCI or the user group DCI, and the terminal can perform CSI measurement and report according to the information corresponding to the terminal in the DCI information after receiving the DCI, so that the system overhead of the network equipment can be reduced.

The CSI feedback resource indication information can be used for indicating channel resources which can be used for CSI reporting by the terminal.

In specific implementation, when receiving the DCI, the terminal may perform CSI measurement and report according to CSI request information and CSI feedback resource indication information corresponding to the terminal included in the DCI.

It can be seen that, in this example, the DCI includes at least one of the following information: the CSI request information and the CSI feedback resource indication information, where one DCI may include configuration information of each terminal in at least one terminal in a user group, is beneficial to reducing system overhead of the network device.

In one possible example, the CSI feedback resource indication information includes: and the physical uplink control channel PUCCH resource indication information or the physical uplink shared channel PUSCH resource indication information.

In one possible example, the DCI includes at least one of: CSI request information, PUCCH resource indication information, and a PDSCH-to-HARQ _ feedback timing indicator.

Specifically, one DCI may include a plurality of blocks, each block corresponds to one user, that is, one terminal, each block may include the foregoing multiple types of information, and the terminal may perform CSI measurement and report according to information in the block corresponding to the terminal.

In one possible example, the DCI includes information of at least one of: CSI request information, time domain resource allocation information, frequency domain resource allocation information, a frequency hopping flag, and a modulation and coding scheme.

In a specific implementation, one DCI may include multiple blocks, where each block corresponds to one user, that is, one terminal, and each block may include the following information: the terminal can measure and report the CSI according to the information in the block corresponding to the terminal.

In the embodiment of the present application, the electronic device may be divided into the functional units according to the method example, for example, each functional unit may be divided corresponding to each function, or two or more functions may be integrated into one processing unit. The integrated unit can be realized in a form of hardware, and can also be realized in a form of a software functional unit.
