As shown in the figure, the data transmission system 10 may include: a terminal 100 and a network device 200 (only one network device is schematically shown in the figure, and there may be multiple network devices in actual applications). Communication and data transmission can be carried out between the terminal and the network device. For example, the network device can send downlink control information (Downlink control information, DCI) to the terminal and receive a CSI report from the terminal. Correspondingly, the terminal can send a CSI report to the network device and receive a DCI from the network device.

[0043] See also Figure 1B , Figure 1B is a schematic diagram of the structure of an electronic device 300 provided in an embodiment of the present application. The electronic device 300 may be Figure 1A Any terminal or any network device described in the embodiments of the present application, the electronic device 300 includes a processor 310, a memory 320, a communication interface 330 and one or more programs 321, wherein the one or more programs 321 are stored in the above-mentioned memory 320 and are configured to be executed by the above-mentioned processor 310, and the one or more programs 321 include instructions for executing any step in the above-mentioned method embodiments.

[0044] Among them, the communication interface 330 is used to support the communication between the first electronic device and other devices. The processor 310 can be, for example, a central processing unit (CPU), a general processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic devices, transistor logic devices, hardware components or any combination thereof.

By way of example and not limitation, many forms of random access memory (RAM) are available, such as static RAM (SRAM), dynamic random access memory (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), synchronous link DRAM (SLDRAM), and direct RAM bus RAM (DR RAM).

[0046] In a specific implementation, the processor 310 is used to execute any step performed by a terminal or a network device in the following method embodiment, and when performing data transmission such as sending, the communication interface 330 can be selectively called to complete the corresponding operation.

[0047] It should be noted that the structural diagram of the above-mentioned electronic device 300 is only an example, and the specific components included may be more or less, and no sole limitation is made here.

[0048] See also Figure 2 , Figure 2 1 is a flow chart of a CSI report transmission method provided in an embodiment of the present application. As shown in the figure, the CSI report transmission method includes:

[0049] Step 201: The terminal sends a CSI report to a network device.

[0050] Step 202: The network device receives a CSI report from a terminal.

[0051] The CSI report is associated with the CSI measurement of the inactive bandwidth part BWP of the current serving cell.

[0052] In a specific implementation, the CSI report may be associated with the CSI measurement of the inactive bandwidth part BWP of the current serving cell, or the CSI report may be associated with the CSI measurement of the active bandwidth part BWP of the current serving cell, or at least one CSI report in the CSI report may be associated with the CSI measurement of the inactive bandwidth part BWP of the current serving cell, or at least one CSI report in the CSI report may be associated with the CSI measurement of the active bandwidth part BWP of the current serving cell.

[0053] In an embodiment of the present application, the terminal sends a CSI report to the network device, and the CSI report is associated with the CSI measurement of the inactive bandwidth part BWP of the current service cell. It can be seen that the embodiment of the present application can also support CSI measurement and reporting in the inactive BWP. Compared with only supporting CSI measurement and reporting in the active BWP, the scope is wider and can support CSI measurement and reporting of non-terrestrial networks, which is conducive to improving the flexibility of network device resource scheduling and improving network performance.

[0054] In one possible example, the priority of the CSI report is determined according to a first parameter group, wherein the first parameter group includes a first parameter, and the first parameter is used to characterize the CSI measurement of the CSI report corresponding to an active BWP, or the first parameter is used to characterize the CSI measurement of an inactive BWP corresponding to the CSI report.

[0055] In specific implementation, when multiple CSI reports need to be reported on the same resource, if the resource size is limited and cannot carry multiple CSI reports, the priorities of different CSI reports are used by the terminal to determine how to perform the corresponding CSI report. The smaller the priority value, the higher the priority of the corresponding CSI report.

[0056] Among them, each CSI report is associated with a priority. When determining the priority of CSI, it can be determined based on multiple parameters. The multiple parameters may include parameters for CSI measurement that characterize the active BWP or inactive BWP corresponding to the CSI report. That is to say, when determining the priority, it will be considered whether the BWP corresponding to the CSI report is an active BWP or an inactive BWP.

[0057] In addition, the value of the priority may also take into account the cell index, CSI reporting content, CSI report type, and CSI report ID, that is, the priority may be defined comprehensively based on the parameters used to characterize the above multiple contents.

[0058] It can be seen that in this example, the priority of the CSI report is determined according to the first parameter group, the first parameter group includes the first parameter, the first parameter is used to characterize the CSI measurement of the CSI report corresponding to the active BWP, or the first parameter is used to characterize the CSI measurement of the CSI report corresponding to the inactive BWP, and determining the priority of the CSI report according to the parameter group including the first parameter is conducive to improving the comprehensiveness and comprehensiveness of the priority determination parameters.

[0059] In a possible 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.

[0060] In a specific implementation, when determining the priority of the CSI report, the first parameter may have two values, corresponding to the situation where the CSI report corresponds to the CSI measurement of the active BWP and the situation where the CSI report corresponds to the CSI measurement of the inactive BWP. Different values ​​of the first parameter are used to characterize different situations. The specific values ​​of the first value and the second value are not limited here and can be set according to actual needs.

[0061] In addition, the value of the priority may also take into account the cell index, CSI reporting content, CSI report type, and CSI report ID, that is, the priority may be defined comprehensively based on the parameters used to characterize the above multiple contents.

[0062] It can be seen that in this example, when the CSI report corresponds to the CSI measurement of the active BWP, the value of the first parameter is the first value, and when the CSI report corresponds to the CSI measurement of the inactive BWP, the value of the first parameter is the second value. Characterizing different situations by different specific values ​​of the first parameter is conducive to improving the accuracy of priority determination.

[0063] In a 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.

[0064] In a specific implementation, the specific values ​​of the first value and the second value can be determined as needed. For example, for a CSI report of CSI measurement carrying an active BWP, the value of the first parameter is 1; for a CSI report of CSI measurement carrying an inactive BWP, the value of the first parameter is 0; or, for a CSI report of CSI measurement carrying an active BWP, the value of the first parameter is 0; for a CSI report of CSI measurement carrying an inactive BWP, the value of the first parameter is 1.

[0065] Specifically, the priority value Pri corresponding to each CSI report iCSI It can be determined by the following formula:

[0066] Pri iCSI (y,k,c,s)=2×N cells ×M S ×y+N cells ×M S ×k+M S ×c+M S ×l+s,

[0067] Among them, for the non-periodic CSI report scheduled to be carried on the physical uplink shared channel (PUSCH), the value of y is 0; for the semi-persistently scheduled CSI report scheduled to be carried on the PUSCH, the value of y is 1; for the semi-persistently scheduled CSI report scheduled to be carried on the physical uplink control channel (PUCCH), the value of y is 2; for the periodic CSI report scheduled to be carried on the PUCCH, the value of y is 3;

[0068] For CSI reports carrying Layer 1 Reference Signal Received Power (L1-RSRP) or Layer 1 Signal to Interference plus Noise Ratio (L1-SINR), the value of k is 0; for CSI reports carrying non-L1-RSRP or L1-SINR, the value of k is 1;

[0069] c is the cell index value, N cells It is the value of the high-level parameter maxNrofServingCells;

[0070] l is the first parameter. For the CSI report of the CSI measurement of the active BWP, the value of l is 1; for the CSI report of the CSI measurement of the inactive BWP, the value of l is 0; or, for the CSI report of the CSI measurement of the active BWP, the value of l is 0; for the CSI report of the CSI measurement of the inactive BWP, the value of l is 1;

[0071] s is reportConfigID, M S It is the value of the higher-level parameter maxNrofCSI-ReportConfigurations.

[0072] 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. Different situations are characterized by different specific values ​​of the first parameter, which is conducive to improving the accuracy of priority determination.

[0073] In a possible example, before the network device receives the CSI report from the terminal, the method further includes: the network device sends a DCI to the terminal, where the DCI is used to instruct the terminal to perform the CSI measurement, and the DCI is a public DCI or a user group DCI.

[0074] In this possible example, before the terminal sends a CSI report to the network device, the method also includes: the terminal receives downlink control information DCI from the network device, the DCI is used to instruct the terminal to perform the CSI measurement, and the DCI is a public DCI or a user group DCI.

[0075] Generally speaking, before sending a CSI report to a network device, the terminal receives DCI from the network device and performs CSI measurement according to the DCI instruction. Considering that the current non-periodic CSI measurement and reporting only supports triggering through unicast DCI, the unicast method will bring too much system overhead to the network device.

[0076] Therefore, the DCI received by the terminal from the network device may be a public DCI or a user group DCI. One DCI may contain the configuration information of each terminal in at least one terminal in the user group, that is, the network device may trigger multiple users to perform non-periodic CSI measurement and reporting by broadcast or multicast, thereby reducing the system overhead of the network device.

[0077] The at least one terminal may be all or part of all terminals included in the current user group.

[0078] For example, assuming that user group A contains 5 terminals, namely terminal 1, terminal 2, terminal 3, terminal 4, and terminal 5, the DCI can include the configuration information of the three terminals, terminal 1, terminal 2, and terminal 3, that is, the network device can instruct terminal 1, terminal 2, and terminal 3 to perform CSI measurement respectively through the DCI.

[0079] For another example, assuming that user group A contains 5 terminals, namely terminal 1, terminal 2, terminal 3, terminal 4, and terminal 5, the DCI may include the configuration information of terminal 1, terminal 2, terminal 3, terminal 4, and terminal 5, i.e., all five terminals in the current user group. That is, the network device can instruct terminal 1, terminal 2, terminal 3, terminal 4, and terminal 5 to perform CSI measurement respectively through the DCI.

[0080] It can be seen that in this example, the DCI received by the terminal from the network device is public DCI or user group DCI, which is beneficial to reducing the system overhead of the network device.

[0081] In a possible example, the DCI includes at least one of the following information: CSI request information and CSI feedback resource indication information.

[0082] In a specific implementation, the DCI is a public DCI or a user group DCI, and one DCI may include information corresponding to one terminal or each terminal in multiple 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 the terminal receives the DCI, it can perform CSI measurement and reporting according to its own CSI request information and CSI feedback resource indication information included in the DCI. The CSI feedback resource indication information can be used to indicate the channel resources on which the terminal can perform CSI reporting. The DCI contains multiple groups of configuration information for multiple terminals, which is conducive to reducing system overhead.

[0083] It can be seen that, in this example, the DCI may include CSI request information and / or CSI feedback resource indication information, so that the network device can instruct the terminal to perform CSI measurement of the inactive BWP.

[0084] In a possible example, the CSI feedback resource indication information includes at least one of the following: physical uplink control channel PUCCH resource indication information and physical uplink shared channel PUSCH resource indication information.

[0085] In a specific implementation, the CSI feedback resource indication information may be PUCCH resource indication information or PUSCH resource indication information. The terminal may report CSI according to the PUCCH resource or PUSCH resource specifically indicated in the CSI feedback resource indication information.

[0086] It can be seen that in this example, the CSI feedback resource indication information includes at least one of the following: PUCCH resource indication information and PUSCH resource indication information. The terminal can report CSI according to the CSI feedback resource indication information, which is conducive to improving the accuracy of CSI reporting resource allocation.

[0087] In a possible 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.

[0088] Among them, the PDSCH-to-HARQ_feedback timing indicator can be used to indicate how long it takes to send HARQ-ACK information after detecting or receiving the CSI-RS.

[0089] The specific design of DCI can be as follows:

[0090] DCI content:

[0091] [block 1,block 2,block 3,…],

[0092] block 1=[CSI request,PUCCH resource indicator,PDSCH-to-HARQ_feedbacktiming indicator]

[0093] Among them, one DCI includes multiple blocks, each block corresponds to a user, that is, a terminal, and the terminal can obtain its corresponding block according to high-level information. CSI request is CSI request information, and PUCCH resource indicator is PUCCH resource indication information.

[0094] Block 1 is an exemplary block. The information type included in any other block can be consistent with block 1. Different blocks correspond to different terminals. The terminal can perform CSI measurement and reporting according to the information in the block corresponding to the terminal.

[0095] 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_feedbacktiming indicator. A DCI can include configuration information of each terminal in at least one terminal in the user group, which is beneficial to reducing the system overhead of the network device.

[0096] In a possible example, the DCI includes at least one of the following information: CSI request information, time domain resource allocation information, frequency domain resource allocation information, frequency hopping flag, and modulation and coding scheme.

[0097] The specific design of DCI can be as follows:

[0098] DCI content:

[0099] [block 1,block 2,block 3,…],

[0100] block 1=[CSI request, Time domain resource assignment, Frequencydomain resource assignment, Frequency hopping flag, Modulation and coding scheme]

[0101] Among them, CSI request is CSI request information, Time domain resource assignment is time domain resource allocation information, Frequency domain resource assignment is frequency domain resource allocation information, Frequencyhopping flag is frequency hopping flag, and Modulation and coding scheme is modulation and coding scheme.

[0102] Block 1 is an exemplary block. The information type included in any other block can be consistent with block 1. Different blocks correspond to different terminals. The terminal can perform CSI measurement and reporting according to the information in the block corresponding to the terminal.

[0103] 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, frequency hopping flag, modulation and coding scheme. A DCI can include configuration information of each terminal in at least one terminal in the user group, which is conducive to reducing the system overhead of the network device.

[0104] See also Figure 3 , Figure 3 FIG. 1 is a flow chart of another CSI report transmission method provided in an embodiment of the present application. As shown in the figure, the CSI report transmission method includes the following steps:

[0105] Step 301: The network device sends DCI to the terminal.

[0106] Step 302: The terminal receives DCI from a network device.

[0107] The DCI is used to instruct the terminal to perform CSI measurement, and the DCI is a public DCI or a user group DCI.

[0108] Generally speaking, before sending a CSI report to a network device, the terminal receives DCI from the network device and performs CSI measurement according to the DCI instruction. Considering that the current non-periodic CSI measurement and reporting only supports triggering through unicast DCI, the unicast method will bring too much system overhead to the network device.

[0109] Therefore, the DCI received by the terminal from the network device may be a public DCI or a user group DCI. One DCI may include the configuration information of each terminal in at least one terminal in the user group, that is, the network device may trigger multiple user terminals to perform non-periodic CSI measurement and reporting by broadcast or multicast, thereby reducing the system overhead of the network device.

[0110] In the embodiment of the present application, the terminal receives DCI from the network device, wherein the DCI is used to instruct the terminal to perform CSI measurement, and the DCI is a public DCI or a user group DCI. It can be seen that in the embodiment of the present application, the DCI received by the terminal from the network device is a public DCI or a user group DCI, and the terminal can perform CSI measurement and reporting according to the information corresponding to the terminal in the DCI information, which is conducive to reducing the system overhead of the network device.

[0111] In a possible example, the DCI includes at least one of the following information: CSI request information and CSI feedback resource indication information.

[0112] The CSI feedback resource indication information may be used to indicate the channel resources on which the terminal can perform CSI reporting.

[0113] In a specific implementation, when a terminal receives DCI, it can perform CSI measurement and reporting according to the CSI request information and CSI feedback resource indication information corresponding to the terminal included in the DCI.

[0114] It can be seen that in this example, the DCI includes at least one of the following information: CSI request information, CSI feedback resource indication information. One DCI may include configuration information of each terminal in at least one terminal in the user group, which is beneficial to reducing the system overhead of the network device.

[0115] In a possible example, the CSI feedback resource indication information includes: physical uplink control channel PUCCH resource indication information, or physical uplink shared channel PUSCH resource indication information.

[0116] In a specific implementation, the CSI feedback resource indication information may be PUCCH resource indication information or PUSCH resource indication information. The terminal may report CSI according to the PUCCH resource or PUSCH resource specifically indicated in the CSI feedback resource indication information.

[0117] It can be seen that in this example, the CSI feedback resource indication information includes at least one of the following: PUCCH resource indication information and PUSCH resource indication information. The terminal can report CSI according to the CSI feedback resource indication information, which is conducive to improving the accuracy of CSI reporting resource allocation.

[0118] In a possible example, the DCI includes at least one of the following information: CSI request information, PUCCH resource indication information, and PDSCH-to-HARQ_feedback timing indicator.

[0119] Specifically, a DCI may include multiple blocks, each block corresponds to a user, that is, a terminal, each block may include the aforementioned multiple information, and the terminal may perform CSI measurement and reporting according to the information in the block corresponding to the terminal.

[0120] 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_feedbacktiming indicator. A DCI can include configuration information of each terminal in at least one terminal in the user group, which is beneficial to reducing the system overhead of the network device.

[0121] In a possible example, the DCI includes at least one of the following information: CSI request information, time domain resource allocation information, frequency domain resource allocation information, frequency hopping flag, and modulation and coding scheme.

[0122] In a specific implementation, a DCI may include multiple blocks, each block corresponds to a user, i.e., a terminal. Each block may include the following information: CSI request information, time domain resource allocation information, frequency domain resource allocation information, frequency hopping flag, and modulation and coding scheme. The terminal may perform CSI measurement and reporting based on the information in the block corresponding to the terminal.

[0123] 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, frequency hopping flag, modulation and coding scheme. A DCI can include configuration information of each terminal in at least one terminal in the user group, which is conducive to reducing the system overhead of the network device.

[0124] The embodiment of the present application can divide the electronic device into functional units according to the above method example. For example, each functional unit can be divided according to each function, or two or more functions can be integrated into one processing unit.
