Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to an information processing method, apparatus, device, storage medium, and computer program product. Background Technology

[0002] Currently, when Channel State Information (CSI) is transmitted on the Physical Uplink Shared Channel (PUSCH), the CSI report reported on the PUSCH is divided into two parts: CSI Part 1 and CSI Part 2. For Type I Part 1, the parameters include: Rank Indicator (RI), Channel State Information Reference Signal Resource Indicator (CRI), and Channel Quality Indicator (CQI). For Type II Part 1, the parameters include: RI and CQI. For Type I Part 2, the parameters include Precoding Matrix Indicator (PMI) and CQI; for Type II Part 2, the parameter includes PMI. Because the base station cannot predict the exact size of Part 2 CSI, the uplink grant resources pre-configured by the base station may not be able to accommodate the entire CSI payload. Therefore, the terminal will discard the transmission of Part 2 CSI according to pre-set priority rules. However, the current implementation of discarding parts of the CSI report is relatively simple, resulting in poor robustness of CSI report transmission. Summary of the Invention

[0107] Before introducing the technical solutions of the embodiments of this application, the relevant technologies will be introduced first.

[0108] See Figure 1 , Figure 1 A schematic diagram of a CSI report in related technologies, such as Figure 1 As shown, the CSI discarding process in a New Radio (NR) system can be as follows: When a CSI is transmitted on the Physical Uplink Shared Channel (PUSCH), the CSI feedback reported on the PUSCH is divided into two parts. These two parts include:

[0109] Part 1: Fixed payload size; the size of Part 2 is determined based on the parameters in Part 1.

[0110] Part 1 includes the following parameters:

[0111] Type I: Rank Indicator (RI), CRI, Channel Quality Indicator (CQI) (First Codeword);

[0112] Type II: RI, CQI, number of non-zero bandwidth amplitudes per layer.

[0113] Part 2: The payload may vary greatly.

[0114] Part 2 includes the following parameters:

[0115] Type I: Precoding Matrix Indicator (PMI), CQI (Second Codeword, RI>4);

[0116] Type II: PMI.

[0117] It should be noted that Part 1 and Part 2 are decoded independently, with Part 1 being decoded first.

[0118] In related technologies, since the base station cannot predict the exact size of Part 2 CSI, the uplink grant resources pre-configured by the base station may not be able to accommodate the entire CSI payload. Therefore, it is necessary to discard the transmission of Part 2 CSI according to the priority rules shown in Table 1. As shown in Table 1, priority 0 is the highest priority, and priority 2N is the lowest. REP It is the lowest priority, N REP It is an integer greater than or equal to 1.

[0119] Table 1

[0120]

[0121]

[0122]

[0124]

[0125] Here, when a CSI report configuration (CSI-ReportConfig) contains a list of sub-configurations, and the corresponding CSI report (report) contains one or more CSI subreports, then the discarding of Part 2 CSIs of the same priority in Table 1 should be performed at the granularity of the sub-configuration. The smaller the value of the CSI sub-report configuration identifier (CSI-ReportSubConfigID) corresponding to the sub-configuration, the higher the priority of the CSI subreport.

[0126] Currently, it is necessary to discuss how to discard partial information in CSI reports when the number of CRIs is greater than or equal to 1. Simultaneously, CSI reporting when the number of CRIs is greater than or equal to 1, and the corresponding number of CQI / RI / PMIs is also greater than or equal to 1, also needs further enhancement. Furthermore, in this case, Part 2 of the CSI report may include a PMI number greater than or equal to 1 and a CQI number greater than or equal to 1 (corresponding to the second codeword). Therefore, the CSI discarding mechanism needs to be redesigned.

[0127] Based on this, in this embodiment of the application, when a CSI report includes first information, the terminal discards the second information in the CSI report; the second information is a part of the first information, or the first information; wherein, the first information includes N third information; the N third information are N CSI parts, or fourth information, or N fifth information; the fourth information is CRI and the corresponding CSI information, and the fifth information is CSI information corresponding to CSI reference signal resources; N is an integer greater than or equal to 1; the discarding of the second information in the CSI report includes one of the following: discarding the second information in the CSI report according to a first method; discarding the second information in the CSI report according to a second method; the second method is different from the first method; discarding the second information in the CSI report according to the priority of the N third information.

[0128] See Figure 2 , Figure 2 This is a schematic flowchart illustrating the implementation of the information processing method according to an embodiment of this application, applied to a terminal. The method includes step 201:

[0129] Step 201: If a CSI report includes first information, discard the second information in the CSI report; the second information is a part of the first information, or the first information; wherein, the first information includes N third information; the N third information are N CSI parts, N fourth information, or N fifth information; the fourth information is CRI and the corresponding CSI information, and the fifth information is CSI information corresponding to CSI reference signal resources; N is an integer greater than or equal to 1;

[0130] Discarding the second information in the CSI report includes one of the following:

[0131] In accordance with the first method, the second information in the CSI report is discarded;

[0132] The second method involves discarding the second information in the CSI report; this second method differs from the first method.

[0133] The second information in the CSI report is discarded according to the priority of the N third information items.

[0134] Here, N CSI parts can refer to N CSI subgroups, where each CSI subgroup includes 0 or 1 CRI.

[0135] Here, N fourth pieces of information can refer to N sets of information; each set of information includes CRI and corresponding CSI information, specifically 1 CRI, 1 rank indicator (RI), 1 precoding matrix indicator (PMI), 1 or 2 channel quality indicators (CQI), etc.

[0136] Here, the N fourth pieces of information can also be described as N CRIs and their corresponding CSI information.

[0137] Here, N fifth pieces of information can refer to N groups of information; each group of information includes CSI information corresponding to the CSI reference signal resource, specifically 0 or 1 CRI, 1 RI, 1 PMI, 1 or 2 CQI, etc.

[0138] Here, the N fifth pieces of information can also be described as CSI information corresponding to N CSI reference signal resources.

[0139] The process of discarding the second piece of information in the CSI report will be explained in detail below, depending on the circumstances.

[0140] In the first scenario, the second information in the CSI report is discarded based on the CRI contained in the CSI report, or the CSI reference signal resource corresponding to the CSI report.

[0141] Based on this, in some embodiments, discarding the second information in the CSI report according to the first method includes:

[0142] Based on the CRI contained in the CSI report or the CSI reference signal resource corresponding to the CSI report, determine the first priority of the first part of the CSI in the CSI report;

[0143] According to the first priority, the first part of the CSI report is discarded.

[0144] In some embodiments, the method for determining the first priority includes:

[0145] The smaller the CRI value included in the CSI report, the higher the priority of the first part of the CSI report;

[0146] or,

[0147] The higher the value of the CRI included in the CSI report, the higher the priority of the first part of the CSI report.

[0148] or,

[0149] The smaller the index of the CSI reference signal resource corresponding to the CSI report, the higher the priority of the first part of the CSI in the CSI report;

[0150] or,

[0151] The larger the index of the CSI reference signal resource corresponding to the CSI report, the higher the priority of the first part of the CSI in the CSI report;

[0152] or,

[0153] If the CSI reference signal resource corresponding to the CSI report appears earlier in the CSI reference signal resource set, then the first part of the CSI in the CSI report has a higher priority.

[0154] or,

[0155] The later the CSI reference signal resource corresponding to the CSI report is arranged in the CSI reference signal resource set, the higher the priority of the first part of the CSI in the CSI report.

[0156] Here, taking the example that the CSI report includes N CSI parts, i.e. N CSI subgroups, the priority of the first part of the CSI report can refer to the priority of the CSI subgroup of the CSI report.

[0157] For example, suppose a CSI report includes three CSI sections, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. Each CSI sub-group includes a CRI, denoted as CRI1, CRI2, and CRI3. If CRI1 has the lowest value, CRI2 has the next lowest value, and CRI3 has the highest value, then CSI sub-group1 has the highest priority in the CSI report, followed by CSI sub-group2, and CSI sub-group3 has the lowest priority. Alternatively, CSI sub-group1 may have the lowest priority, followed by CSI sub-group2, and CSI sub-group3 has the highest priority.

[0158] For example, suppose a CSI report includes three CSI sections, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. CSI sub-group1 corresponds to CSI RS resource 1, CSI sub-group2 to CSI RS resource 2, and CSI sub-group3 to CSI RS resource 3. Assuming CSI RS resource 1 has the smallest index, CSI RS resource 2 has the second largest index, and CSI RS resource 3 has the largest index, then CSI sub-group1 has the highest priority in the CSI report, followed by CSI sub-group2, and CSI sub-group3 has the lowest priority; or, conversely, CSI sub-group1 has the lowest priority, CSI sub-group2 has the second largest priority, and CSI sub-group3 has the highest priority.

[0159] For example, suppose a CSI report includes three CSI sections, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. CSI sub-group1 corresponds to CSI reference signal resources including CSI RS resource 1, CSI sub-group2 corresponds to CSI RS resource 2, and CSI sub-group3 corresponds to CSI RS resource 3. Assuming the set of CSI reference signal resources is {CSI RS resource 1, CSI RS resource 2, CSI RS resource 3}, then CSI sub-group1 has the highest priority in the CSI report, followed by CSI sub-group2, and CSI sub-group3 has the lowest priority; or, CSI sub-group1 has the lowest priority, followed by CSI sub-group2, and CSI sub-group3 has the highest priority.

[0160] It should be noted that the method for determining the first priority for N fourth pieces of information or N fifth pieces of information is similar to the method for determining the N CSI parts, and will not be repeated here.

[0161] Furthermore, discarding the first portion of the CSI report according to the first priority may include:

[0162] The lower the first priority of the first part of CSI, the higher the priority of discarding it; conversely, the higher the first priority of the first part of CSI, the higher the priority of retaining it.

[0163] For example, suppose a CSI report includes three CSI parts, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. If CSI sub-group1 has the highest priority, followed by CSI sub-group2, and then CSI sub-group3 has the lowest priority, then CSI sub-group3 is discarded first, followed by CSI sub-group2 and CSI sub-group1. Alternatively, CSI sub-group1 is retained first, followed by CSI sub-group2 and CSI sub-group3.

[0164] In the second scenario, the second information in the CSI report is discarded based on the order or corresponding order of the CRIs contained in the CSI report within the CSI report, or based on the order or corresponding order of the CRIs contained in the CSI report within the uplink control information bit sequence.

[0165] Based on this, in some embodiments, discarding the second information in the CSI report according to the first method includes:

[0166] The second priority of the first part of the CSI in the CSI report is determined according to the order or corresponding order of the CRIs contained in the CSI report in the CSI report, or according to the order or corresponding order of the CRIs contained in the CSI report in the uplink control information bit sequence.

[0167] According to the second priority, the first part of the CSI report is discarded.

[0168] Here, taking the example that the CSI report includes N CSI parts, i.e. N CSI subgroups, the priority of the first part of the CSI report can refer to the priority of the CSI subgroup of the CSI report.

[0169] In some embodiments, the method for determining the second priority includes:

[0170] If the CRIs included in the CSI report appear earlier in the CSI report or in the corresponding order, then the first part of the CSI in the CSI report has a higher priority.

[0171] or,

[0172] If the CRIs included in the CSI report are listed later in the CSI report, the first part of the CSI in the CSI report has a higher priority.

[0173] or,

[0174] If the CRI included in the CSI report appears earlier in the uplink control information bit sequence, the higher the priority of the first part of the CSI in the CSI report.

[0175] or,

[0176] The later the CRI in the uplink control information bit sequence is in the CSI report, the higher the priority of the first part of the CSI in the CSI report.

[0177] For example, suppose a CSI report includes three CSI sections, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. Each CSI sub-group includes one CRI, denoted as CRI1, CRI2, and CRI3. If the three CRIs are arranged or correspondingly ordered in the CSI report as CRI1, CRI2, and CRI3, then CSI sub-group1 has the highest priority, followed by CSI sub-group2, and CSI sub-group3 has the lowest priority. Alternatively, CSI sub-group1 has the lowest priority, followed by CSI sub-group2, and CSI sub-group3 has the highest priority.

[0178] For example, suppose a CSI report includes three CSI sections, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. Each CSI sub-group includes one CRI, denoted as CRI1, CRI2, and CRI3. The CSI report also includes an uplink control information (UCI) bit sequence. Assuming the three CRIs are arranged or corresponding to each other in the uplink control information bit sequence in the order of CRI1, CRI2, and CRI3, then CSI sub-group1 has the highest priority in the CSI report, followed by CSI sub-group2, and CSI sub-group3 has the lowest priority; or, CSI sub-group1 has the lowest priority, followed by CSI sub-group2, and CSI sub-group3 has the highest priority.

[0179] It should be noted that the method for determining the second priority for N fourth pieces of information or N fifth pieces of information is similar to the method for determining the N CSI parts, and will not be repeated here.

[0180] Furthermore, discarding the first portion of the CSI report according to the second priority may include:

[0181] The lower the second priority of the first part of the CSI, the higher the priority to discard it; conversely, the higher the second priority of the first part of the CSI, the higher the priority to retain it.

[0182] For example, suppose a CSI report includes three CSI parts, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. If CSI sub-group1 has the highest priority, followed by CSI sub-group2, and then CSI sub-group3 has the lowest priority, then CSI sub-group3 is discarded first, followed by CSI sub-group2 and CSI sub-group1. Alternatively, CSI sub-group1 is retained first, followed by CSI sub-group2 and CSI sub-group3.

[0183] In the third scenario, the second piece of information in the CSI report is discarded according to the third priority.

[0184] Based on this, in some embodiments, discarding the second information in the CSI report according to the first method includes:

[0185] The first part of the CSI report is discarded according to the third priority.

[0186] in,

[0187] The third priority is determined in the following order:

[0188] For multiple CSI reports, the broadband CSIs included in the first part of each CSI report have the same priority and the highest priority;

[0189] For multiple CSI reports, if the number of the CSI report is smaller and the number of the CSI section is smaller, then the even-numbered subband CSIs contained in the first part of the CSI report have higher priority.

[0190] For multiple CSI reports, if the number of the CSI report is smaller and the number of the CSI section is smaller, then the odd-numbered subband CSIs contained in the first part of the CSI report have higher priority.

[0191] If the CSI reports have the same number, the even-numbered subband CSIs included in the first part of the CSI report have a higher priority than the odd-numbered subband CSIs included in the first part of the CSI report.

[0192] Here, the CSI report includes N CSI parts, i.e., N CSI subgroups; the statement that for multiple CSI reports, the broadband CSIs contained in the first part of each CSI report have the same priority and the highest priority can mean that the broadband CSIs in all CSI subgroups have the same priority.

[0193] Here, the priority of the even-numbered subbands of CSI included in the first part of the CSI report may refer to the priority of Part 2 of the CSI in the even-numbered subbands of the CSI subgroup of the CSI report.

[0194] Here, the priority of the odd-numbered subband CSIs included in the first part of the CSI report may refer to the priority of Part 2 CSI of the odd-numbered subbands in the CSI subgroup of the CSI report.

[0195] For example, suppose there are two CSI reports, denoted as CSI Report 1 and CSI Report 2. Each CSI report includes three CSI parts, or three CSI subgroups, denoted as CSI subgroup1, CSI subgroup2, and CSI subgroup3. For CSI Report 1, the CSI Part 2 (CSI 2CSI) of the even-numbered subbands in CSI subgroup1 has the highest priority, followed by the Part 2CSI of the even-numbered subbands in CSI subgroup2 and the Part 2CSI of the even-numbered subbands in CSI subgroup3. Next, the CSI Part 2 (CSI 2CSI) of the odd-numbered subbands in CSI subgroup1 has the highest priority, followed by the Part 2CSI of the odd-numbered subbands in CSI subgroup2 and the Part 2CSI of the odd-numbered subbands in CSI subgroup3. 2CSI; where, for the same CSI report 1, the priority of Part 2CSI in even-numbered subbands of the CSI subgroup is higher than the priority of Part 2CSI in odd-numbered subbands of the CSI subgroup; for CSI report 2, the third priority is determined in a similar way to that of CSI report 1.

[0196] It should be noted that the method for determining the third priority for N fourth or N fifth pieces of information is similar to the method for determining the N CSI parts, and will not be repeated here.

[0197] Furthermore, the step of discarding the first portion of the CSI report according to the third priority may include:

[0198] The lower the third priority of the first part of the CSI, the higher the priority for discarding; conversely, the higher the third priority of the first part of the CSI, the higher the priority for retaining.

[0199] In the fourth scenario, the second piece of information in the CSI report is discarded according to the fourth priority.

[0200] Based on this, in some embodiments, discarding the second information in the CSI report according to the second method includes:

[0201] The first part of the CSI report is discarded according to the fourth priority.

[0202] in,

[0203] The fourth priority is determined in the following order:

[0204] For multiple CSI reports, the broadband CSIs included in the first part of each CSI report have the same priority and the highest priority;

[0205] For multiple CSI reports, if the number of the CSI report is smaller and the number of the CSI section is smaller, then the first part of the CSI report has a higher priority.

[0206] Wherein, if the CSI reports have the same number and the CSI parts have the same number, then the even-numbered subband CSIs included in the first part of the CSI report have a higher priority than the odd-numbered subband CSIs included in the first part of the CSI report; if the CSI reports have the same number and the number of the first CSI part is less than the number of the second CSI part, then the odd-numbered subband CSIs included in the first CSI part have a higher priority than the even-numbered subband CSIs included in the second CSI part; the first CSI part and the second CSI part are different.

[0207] Here, the CSI report includes N CSI parts, i.e., N CSI subgroups; the statement that for multiple CSI reports, the broadband CSIs contained in the first part of each CSI report have the same priority and the highest priority can mean that the broadband CSIs in all CSI subgroups have the same priority.

[0208] Here, the priority of the even-numbered subbands of CSI included in the first part of the CSI report may refer to the priority of Part 2 of the CSI in the even-numbered subbands of the CSI subgroup of the CSI report.

[0209] Here, the priority of the odd-numbered subband CSIs included in the first part of the CSI report may refer to the priority of Part 2 CSI of the odd-numbered subbands in the CSI subgroup of the CSI report.

[0210] Here, the first CSI part can refer to the first CSI sub-group among N CSI sub-groups; the second CSI part can refer to the second CSI sub-group among N CSI sub-groups; the number of the first CSI sub-group is less than the number of the second CSI sub-group.

[0211] For example, suppose there are two CSI reports, denoted as CSI Report 1 and CSI Report 2. Each CSI report includes three CSI parts, or three CSI subgroups, denoted as CSI subgroup 1, CSI subgroup 2, and CSI subgroup 3. For CSI Report 1, the CSI Part 2CSI in the even-numbered subbands of CSI Subgroup 1 has a higher priority than the Part 2CSI in the odd-numbered subbands of CSI Subgroup 1. Next, the Part 2CSI in the even-numbered subbands of CSI Subgroup 2 has a higher priority than the Part 2CSI in the odd-numbered subbands of CSI Subgroup 2. Finally, the Part 2CSI in the even-numbered subbands of CSI Subgroup 3 has a higher priority than the Part 2CSI in CSI Report 1. The priority of Part 2 CSI in odd-numbered subbands of sub-group 3; for CSI report 2, the fourth priority is determined in a similar way to that of CSI report 1.

[0212] It should be noted that the method for determining the fourth priority for N fourth pieces of information or N fifth pieces of information is similar to the method for determining the N CSI parts, and will not be repeated here.

[0213] Furthermore, the step of discarding the first portion of the CSI report according to the fourth priority may include:

[0214] The lower the fourth priority of the first part of CSI, the higher the priority for discarding; conversely, the higher the fourth priority of the first part of CSI, the higher the priority for retention.

[0215] In some embodiments, the numbering of the CSI section is determined based on one of the following:

[0216] The number associated with the CSI section;

[0217] The CSI report contains or is associated with a CRI;

[0218] Based on the arrangement or corresponding order of CRI in the uplink control information bit sequence in the CSI report;

[0219] Based on the order of the CSI reference signal resources corresponding to the CSI report in the CSI reference signal resource set.

[0220] Here, the number associated with the CSI part can refer to the sub-group ID contained in or associated with the CSI sub-group. For example, if the sub-group ID is 1, then the number of the CSI part, i.e., the CSI sub-group, is 1.

[0221] Here, the CRI contained or associated in the CSI report can refer to the CRI contained or associated in the CSI subgroup of the CSI report. For example, if the identifier of the CRI is CRI1, then the CSI part, i.e., the CSI subgroup, is numbered 1.

[0222] Here, assuming that the CRI in the CSI report is the first in the uplink control information bit sequence, then the CSI section, i.e., the CSI sub-group, is numbered 1.

[0223] Here, assuming that the CSI reference signal resource corresponding to the CSI report is the first one in the CSI reference signal resource set, then the CSI part, i.e., the CSI sub-group, is numbered 1.

[0224] In the fifth scenario, the second information in the CSI report is discarded according to the priority of the N third pieces of information.

[0225] Based on this, in some embodiments, the method further includes:

[0226] Determine at least one of the following parameters: a first parameter, a second parameter, a third parameter, a fourth parameter, a fifth parameter, and a sixth parameter; wherein, the first parameter represents the identifier associated with the CSI portion, or the identifier of the CRI, or the value of the CRI, or the relative position identifier of the CRI, or the relative position identifier of the CSI portion; the second parameter represents the maximum number of CSIs configured by the higher layer, or the maximum number of CRIs that can be supported, or the maximum number of CSIs that can be supported per CSI report, or the maximum number of CSIs that can be supported corresponding to the maximum number of CSI reference signal resources; the third parameter represents the CSI report type; the fourth parameter represents the CSI type carried in the CSI report; the fifth parameter represents the serving cell index; and the sixth parameter represents the CSI report configuration identifier.

[0227] The priority of the N pieces of third information is determined based on at least one of the first parameter, the second parameter, the third parameter, the fourth parameter, the fifth parameter, and the sixth parameter;

[0228] The determination of the priority of the N third pieces of information includes one of the following:

[0229] Determine the priority of each of the N CSI sections;

[0230] Determine the priority of each of the N pieces of fourth information;

[0231] Determine the priority of each of the N pieces of fifth information.

[0232] Here, the first parameter represents the identifier associated with the CSI part, or the identifier of the CRI, or the value of the CRI, or the relative position identifier of the CRI, or the relative position identifier of the CSI part, that is, the sub-group ID contained or associated in the CSI sub-group, or the CRI ID, or the value of the CRI, or the relative position identifier of the CRI, or the relative position identifier of the CSI part.

[0233] The CRI ID definition can be one of the following:

[0234] Definition 1: There are N CRIs in N CSI subgroups. After sorting the N CRIs in ascending order, the ID of the x-th smallest CRI is x, where x = 0, ..., N-1, and N is an integer greater than or equal to 1.

[0235] Definition 2: The CRI ID corresponding to the x-th CRI in the uplink control information (UCI) bit sequence is defined as x, or the CRI ID corresponding to the x-th CSI sub-group is defined as x, where x = 0, ..., N-1, and N is an integer greater than or equal to 1.

[0236] The relative position identifier of the CRI can be determined according to the order of the CRI in the uplink control information (UCI) bit sequence. For example, if the CRI is the first in the uplink control information (UCI) bit sequence, then the relative position identifier of the CRI can be 0 or 1.

[0237] The relative position identifier of the CSI part can be determined according to the arrangement order of the CSI part among the N CSI parts. For example, if the CSI part is the first in the arrangement order among the N CSI parts, then the relative position identifier of the CSI part is 0 or 1.

[0238] Here, the second parameter represents the maximum number of CSIs configured by the higher layer or the maximum number of CRIs that can be supported, or the maximum number of CSIs that each CSI report can support or the maximum number of CRIs that can be supported or the maximum number of CSIs reported corresponding to the maximum number of CSI reference signal resources that can be supported.

[0239] Here, the third parameter characterizes the CSI report type, which may specifically include non-periodic CSI report carried on PUSCH, semi-persistent CSI report carried on PUSCH, semi-persistent CSI report carried on PUCCH, and periodic CSI report carried on PUCCH.

[0240] Here, the fourth parameter represents the type of CSI carried in the CSI report, which may specifically include CSI reports carrying L1-RSRP or L1-SINR, and CSI reports not carrying L1-RSRP or L1-SINR.

[0241] Here, the fifth parameter represents the serving cell index, that is, the serving cell index configured in the higher-layer signaling.

[0242] Here, the sixth parameter represents the CSI report configuration identifier, namely the reportConfigID of the higher-level signaling configuration.

[0243] Here, determining the priority of each of the N CSI parts can include:

[0244] Multiply the second parameter and the third parameter to obtain the first value;

[0245] The second value is obtained by multiplying the second parameter and the fourth parameter.

[0246] The third value is obtained by multiplying the second parameter and the fifth parameter.

[0247] The product of the second parameter and the sixth parameter is used to obtain the fourth value;

[0248] Based on the first value, the second value, the third value, the fourth value, and the value of the first parameter, the fifth value is obtained;

[0249] The fifth value is used as the priority for each of the N CSI parts.

[0250] It should be noted that the process of calculating the priority of each fourth or fifth piece of information is similar to the process of calculating the priority of each CSI section, and will not be repeated here.

[0251] In some embodiments, discarding the second information in the CSI report according to the priority of the N third information pieces includes:

[0252] According to the priority of the N CSI sections, the CSI sections in the CSI report are discarded;

[0253] or,

[0254] According to the priority of the N fourth pieces of information, the CRI and the corresponding CSI information in the CSI report are discarded;

[0255] or,

[0256] According to the priority of the N fifth pieces of information, the CSI information corresponding to the CSI reference signal resources in the CSI report is discarded.

[0257] Here, the lower the priority, the more likely it is to be discarded, or the higher the priority, the more likely it is to be retained.

[0258] In the sixth case, the second information in the CSI report is discarded according to the priority of the M third information items.

[0259] Based on this, in some embodiments, the method further includes:

[0260] If K CSI reports contain M pieces of third information, the second information in the CSI reports is discarded according to the priority of the M pieces of third information;

[0261] Wherein, K and M are both integers greater than or equal to 1; the M third pieces of information are M CSI parts, M fourth pieces of information, or M fifth pieces of information;

[0262] The priority of the M pieces of third information is determined in the following order:

[0263] For the M third pieces of information, the broadband CSI contained in each third piece of information has the same priority and the highest priority;

[0264] For M pieces of third information, if the priority of the third information is higher, then the priority of the even-numbered subband CSIs contained in the third information is higher, and the priority of the odd-numbered subband CSIs contained in the third information is higher; wherein, for the same piece of third information, the priority of the even-numbered subband CSIs contained in the third information is higher than the priority of the odd-numbered subband CSIs contained in the third information.

[0265] Here, the M third pieces of information are M CSI parts, or M CSI subgroups. The broadband CSIs contained in each of the third pieces of information have the same priority and the highest priority can mean that the broadband CSIs in all CSI subgroups have the same priority.

[0266] Here, the priority of the even-numbered subband CSI included in the third information may refer to the priority of the even-numbered subband CSI Part 2 CSI in the CSI sub-group of the CSI report.

[0267] Here, the priority of the odd-numbered subband CSI included in the third information may refer to the priority of the odd-numbered subband CSI Part 2 CSI in the CSI sub-group of the CSI report.

[0268] Here, the priority of the third information can be determined based on at least one of the first parameter, the second parameter, the third parameter, the fourth parameter, the fifth parameter, and the sixth parameter.

[0269] It should be noted that the priority determination method for M fourth pieces of information or M fifth pieces of information is similar to the determination method for M CSI parts, and will not be repeated here.

[0270] Furthermore, discarding the second information in the CSI report according to the priority of the M pieces of third information may include:

[0271] The lower the priority, the more likely it is to be discarded; conversely, the higher the priority, the more likely it is to be retained.

[0272] In some embodiments, the method further includes:

[0273] The reference signal is measured to obtain channel information;

[0274] Based on the channel information, determine the method for discarding the second information in the CSI report.

[0275] Here, considering that the terminal can use information such as measured channel characteristics, such as the frequency selectivity of the downlink channel, beam differences between multiple measurement resources, and CQI differences, to determine whether a particular dropping method is more suitable for the terminal's channel characteristics.

[0276] Specifically, if the downlink channel frequency selectivity is weak based on the channel information, then method one can be used; if the downlink channel frequency selectivity is strong based on the channel information, then method two can be used.

[0277] In some embodiments, the method further includes:

[0278] The CSI report is sent to the network device; the CSI report includes an indication field; the indication field is used to indicate the method used to discard the second information in the CSI report.

[0279] For example, assuming the indication field occupies 1 bit, when the codepoint of the indication field is 0, it means that the second information in the CSI report is discarded in the first way; when the codepoint of the indication field is 1, it means that the second information in the CSI report is discarded in the second way.

[0280] For example, assuming the indication field occupies 2 bits, when the codepoint of the indication field is 00, it means that the second information in the CSI report is discarded in the first way; when the codepoint of the indication field is 01, it means that the second information in the CSI report is discarded in the second way; when the codepoint of the indication field is 10, it means that the second information in the CSI report is discarded according to the priority of N third information.

[0281] In some embodiments, the method further includes:

[0282] The sixth piece of information in the CSI report, excluding the discarded second piece of information, is sent to the network device.

[0283] The embodiments of this application have the following advantages:

[0284] (1) When a terminal receives a CSI report containing first information, it discards second information in the CSI report; the second information is a part of the first information, or the first information; wherein the first information includes N third information; the N third information are N CSI parts, N fourth information, or N fifth information; the fourth information is CRI and the corresponding CSI information, and the fifth information is CSI information corresponding to CSI reference signal resources; N is an integer greater than or equal to 1; the discarding of the second information in the CSI report includes one of the following: discarding the second information in the CSI report according to a first method; discarding the second information in the CSI report according to a second method; the second method is different from the first method; discarding the second information in the CSI report according to the priority of the N third information.

[0285] As can be seen, there are multiple ways to discard some information in the CSI report in this application embodiment, which helps to improve the robustness of CSI report transmission.

[0286] (2) To support multiple CRIs and their corresponding multiple CSI reports, a variety of CSI discarding mechanisms have been designed, which can effectively improve the transmission robustness of CSI reporting.

[0287] See Figure 3 , Figure 3This is a schematic diagram illustrating the implementation flow of the information processing method according to an embodiment of this application, applied to a network device. The method includes 301:

[0288] Step 301: Receive the sixth information sent by the terminal; wherein, the sixth information is obtained by the terminal discarding the second information in a CSI report when the CSI report includes the first information; the second information is a part of the first information, or the first information; the first information includes N third information; the N third information are N CSI parts, N fourth information, or N fifth information; the fourth information is CRI and the corresponding CSI information, and the fifth information is the CSI information corresponding to the CSI reference signal resource; N is an integer greater than or equal to 1;

[0289] The method of discarding the second information in the CSI report includes one of the following: discarding the second information in the CSI report according to a first method; discarding the second information in the CSI report according to a second method; the second method being different from the first method; or discarding the second information in the CSI report according to the priority of the N third information items.

[0290] In some embodiments, the method further includes:

[0291] The terminal receives the CSI report sent by the terminal; the CSI report includes an indication field; the indication field is used to indicate the method by which the terminal discards the second information in the CSI report.

[0292] For example, assuming the indication field occupies 1 bit, when the codepoint of the indication field is 0, it means that the second information in the CSI report is discarded in the first way; when the codepoint of the indication field is 1, it means that the second information in the CSI report is discarded in the second way.

[0293] For example, assuming the indication field occupies 2 bits, when the codepoint of the indication field is 00, it means that the second information in the CSI report is discarded in the first way; when the codepoint of the indication field is 01, it means that the second information in the CSI report is discarded in the second way; when the codepoint of the indication field is 10, it means that the second information in the CSI report is discarded according to the priority of N third information.

[0294] The embodiments of this application have the following advantages:

[0295] (1) There are several ways to discard some information in the CSI report, which helps to improve the robustness of CSI report transmission.

[0296] (2) To support multiple CRIs and their corresponding multiple CSI reports, a variety of CSI discarding mechanisms have been designed, which can effectively improve the transmission robustness of CSI reporting.

[0297] The technical solutions of the embodiments of this application are described below with reference to specific application examples.

[0298] Example 1

[0299] In the case where a CSI report includes first information, the second information in the CSI report is discarded according to a first method. The first information includes N third information items; the N third information items are N CSI parts, N fourth information items, or N fifth information items. The fourth information items are CRI and their corresponding CSI information, the fifth information items are CSI information corresponding to CSI reference signal resources, N is an integer greater than or equal to 1, and the second information is a part of the first information, or the first information itself.

[0300] Here, N CSI parts can refer to N CSI subgroups, where each CSI subgroup includes 0 or 1 CRI.

[0301] Here, N fourth pieces of information can refer to N sets of information, namely N CRIs and their corresponding CSI information. Each set of information includes CRIs and their corresponding CSI information, specifically 1 CRI, 1 RI, 1 PMI, 1 or 2 CQIs, etc.

[0302] Here, N pieces of fifth information can refer to N sets of information, that is, the CSI information corresponding to N CSI reference signal resources. Each set of information includes the CSI information corresponding to the CSI reference signal resources, specifically 0 or 1 CRI, 1 RI, 1 PMI, 1 or 2 CQI, etc.

[0303] The following example illustrates the process of discarding the second information in the CSI report according to the first method, using the first information comprising N CSI parts as an example.

[0304] Here, a CSI report supports reporting N CSI parts, or N CSI subgroups, where each CSI subgroup includes 0 or 1 CRIs. If the downlink channel has weak frequency selectivity, the second information in the CSI report can be discarded at the CSI subgroup granularity.

[0305] Thus, according to the first method, discarding the second information in the CSI report may include: determining a first priority of the first part of the CSI in the CSI report based on the CRI contained in the CSI report; and discarding the first part of the CSI in the CSI report according to the first priority.

[0306] Specifically, determining the first priority of the first part of the CSI in the CSI report based on the CRI included in the CSI report may include:

[0307] The smaller the CRI value included in the CSI report, the higher the priority of the first part of the CSI report;

[0308] or,

[0309] The higher the value of the CRI included in the CSI report, the higher the priority of the first part of the CSI report.

[0310] In other words, the smaller the CRI value in the CSI report, the higher the priority of the first part of the CSI report, i.e., the CSI sub-group; or, the larger the CRI value in the CSI report, the higher the priority of the first part of the CSI report, i.e., the CSI sub-group.

[0311] For example, suppose a CSI report includes three CSI sections, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. Each CSI sub-group includes a CRI, denoted as CRI1, CRI2, and CRI3. If CRI1 has the lowest value, CRI2 has the next lowest value, and CRI3 has the highest value, then CSI sub-group1 has the highest priority in the CSI report, followed by CSI sub-group2, and CSI sub-group3 has the lowest priority. Alternatively, CSI sub-group1 may have the lowest priority, followed by CSI sub-group2, and CSI sub-group3 has the highest priority.

[0312] In practical applications, discarding the second information in the CSI report according to the first method may further include: determining the first priority of the first part of the CSI in the CSI report based on the CSI reference signal resources corresponding to the CSI report; and discarding the first part of the CSI in the CSI report according to the first priority.

[0313] Specifically, the method for determining the first priority may include:

[0314] The smaller the index of the CSI reference signal resource corresponding to the CSI report, the higher the priority of the first part of the CSI in the CSI report;

[0315] or,

[0316] The larger the index of the CSI reference signal resource corresponding to the CSI report, the higher the priority of the first part of the CSI in the CSI report;

[0317] or,

[0318] If the CSI reference signal resource corresponding to the CSI report appears earlier in the CSI reference signal resource set, then the first part of the CSI in the CSI report has a higher priority.

[0319] or,

[0320] The later the CSI reference signal resource corresponding to the CSI report is arranged in the CSI reference signal resource set, the higher the priority of the first part of the CSI in the CSI report.

[0321] For example, suppose a CSI report includes three CSI sections, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. CSI sub-group1 corresponds to CSI RS resource 1, CSI sub-group2 to CSI RS resource 2, and CSI sub-group3 to CSI RS resource 3. Assuming CSI RS resource 1 has the smallest index, CSI RS resource 2 has the second largest index, and CSI RS resource 3 has the largest index, then CSI sub-group1 has the highest priority in the CSI report, followed by CSI sub-group2, and CSI sub-group3 has the lowest priority; or, conversely, CSI sub-group1 has the lowest priority, CSI sub-group2 has the second largest priority, and CSI sub-group3 has the highest priority.

[0322] For example, suppose a CSI report includes three CSI sections, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. CSI sub-group1 corresponds to CSI reference signal resources including CSI RS resource 1, CSI sub-group2 corresponds to CSI RS resource 2, and CSI sub-group3 corresponds to CSI RS resource 3. Assuming the set of CSI reference signal resources is {CSI RS resource 1, CSI RS resource 2, CSI RS resource 3}, then CSI sub-group1 has the highest priority in the CSI report, followed by CSI sub-group2, and CSI sub-group3 has the lowest priority; or, CSI sub-group1 has the lowest priority, followed by CSI sub-group2, and CSI sub-group3 has the highest priority.

[0323] Furthermore, discarding the first portion of the CSI report according to the first priority may include:

[0324] The lower the first priority of the first part of CSI, the higher the priority of discarding it; conversely, the higher the first priority of the first part of CSI, the higher the priority of retaining it.

[0325] For example, suppose a CSI report includes three CSI parts, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. If CSI sub-group1 has the highest priority, followed by CSI sub-group2, and then CSI sub-group3 has the lowest priority, then CSI sub-group3 is discarded first, followed by CSI sub-group2 and CSI sub-group1. Alternatively, CSI sub-group1 is retained first, followed by CSI sub-group2 and CSI sub-group3.

[0326] In practical applications, discarding the second information in the CSI report according to the first method may further include: determining the second priority of the first part of the CSI in the CSI report based on the arrangement order or corresponding order of the CRIs contained in the CSI report in the CSI report, or based on the arrangement order or corresponding order of the CRIs contained in the CSI report in the uplink control information bit sequence; and discarding the first part of the CSI in the CSI report according to the second priority.

[0327] Specifically, the method for determining the second priority may include:

[0328] If the CRIs included in the CSI report appear earlier in the CSI report or in the corresponding order, then the first part of the CSI in the CSI report has a higher priority.

[0329] or,

[0330] If the CRIs included in the CSI report are listed later in the CSI report, the first part of the CSI in the CSI report has a higher priority.

[0331] or,

[0332] If the CRI included in the CSI report appears earlier in the uplink control information bit sequence, the higher the priority of the first part of the CSI in the CSI report.

[0333] or,

[0334] The later the CRI in the uplink control information bit sequence is in the CSI report, the higher the priority of the first part of the CSI in the CSI report.

[0335] For example, suppose a CSI report includes three CSI sections, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. Each CSI sub-group includes one CRI, denoted as CRI1, CRI2, and CRI3. If the three CRIs are arranged or correspondingly ordered in the CSI report as CRI1, CRI2, and CRI3, then CSI sub-group1 has the highest priority, followed by CSI sub-group2, and CSI sub-group3 has the lowest priority. Alternatively, CSI sub-group1 has the lowest priority, followed by CSI sub-group2, and CSI sub-group3 has the highest priority.

[0336] For example, suppose a CSI report includes three CSI sections, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. Each CSI sub-group includes one CRI, denoted as CRI1, CRI2, and CRI3. The CSI report also includes an uplink control information (UCI) bit sequence. Assuming the three CRIs are arranged or corresponding to each other in the uplink control information bit sequence in the order of CRI1, CRI2, and CRI3, then CSI sub-group1 has the highest priority in the CSI report, followed by CSI sub-group2, and CSI sub-group3 has the lowest priority; or, CSI sub-group1 has the lowest priority, followed by CSI sub-group2, and CSI sub-group3 has the highest priority.

[0337] Furthermore, discarding the first portion of the CSI report according to the second priority may include:

[0338] The lower the second priority of the first part of CSI, the higher the priority of discarding; conversely, the higher the second priority of the first part of CSI, the higher the priority of retaining.

[0339] For example, suppose a CSI report includes three CSI parts, or three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3. If CSI sub-group1 has the highest priority, followed by CSI sub-group2, and then CSI sub-group3 has the lowest priority, then CSI sub-group3 is discarded first, followed by CSI sub-group2 and CSI sub-group1. Alternatively, CSI sub-group1 is retained first, followed by CSI sub-group2 and CSI sub-group3.

[0340] In practical applications, in addition to discarding the second information in the CSI report according to the first method, it may also include discarding the first part of the CSI report according to the third priority.

[0341] Here, the third priority is determined in the following order:

[0342] For multiple CSI reports, the broadband CSIs included in the first part of each CSI report have the same priority and the highest priority;

[0343] For multiple CSI reports, if the number of the CSI report is smaller and the number of the CSI section is smaller, then the even-numbered subband CSIs contained in the first part of the CSI report have higher priority.

[0344] For multiple CSI reports, if the number of the CSI report is smaller and the number of the CSI section is smaller, then the odd-numbered subband CSIs contained in the first part of the CSI report have higher priority.

[0345] If the CSI reports have the same number, the even-numbered subband CSIs included in the first part of the CSI report have a higher priority than the odd-numbered subband CSIs included in the first part of the CSI report.

[0346] Here, the CSI report includes N CSI parts, i.e., N CSI subgroups; the statement that for multiple CSI reports, the broadband CSIs contained in the first part of each CSI report have the same priority and the highest priority can mean that the broadband CSIs in all CSI subgroups have the same priority.

[0347] Here, the priority of the even-numbered subbands of CSI included in the first part of the CSI report may refer to the priority of Part 2 of the CSI in the even-numbered subbands of the CSI subgroup of the CSI report.

[0348] Here, the priority of the odd-numbered subband CSIs included in the first part of the CSI report may refer to the priority of Part 2 CSI of the odd-numbered subbands in the CSI subgroup of the CSI report.

[0349] Furthermore, the step of discarding the first portion of the CSI report according to the third priority may include:

[0350] The lower the third priority of the first part of the CSI, the higher the priority for discarding; conversely, the higher the third priority of the first part of the CSI, the higher the priority for retaining.

[0351] Table 2 illustrates the third priority level. As shown in Table 2, assume there are N... REP One CSI report, N REP A CSI report consists of N CSI subgroups, where N is an integer greater than or equal to 1. The third priority is determined in the following order: first, for N... REP For each CSI report, all broadband CSIs within a CSI subgroup have the same and highest priority. For example, suppose there are two CSI reports, denoted as CSI report 1 and CSI report 2. Each CSI report includes three CSI parts, or three CSI subgroups, denoted as CSI subgroup1, CSI subgroup2, and CSI subgroup3. In this case, all broadband CSIs within a CSI subgroup have the same and highest priority. Next is the priority for N... REP For each CSI report, if the CSI report number and the CSI sub-group number are both smaller, then the Part 2 CSI of the even-numbered subbands within the CSI sub-group of that CSI report has a higher priority; for N REPFor each CSI report, the smaller the CSI report number and the smaller the CSI sub-group number, the higher the priority of Part 2 CSI in the odd-numbered subbands of that CSI report's CSI sub-group. However, if the CSI reports have the same number, the even-numbered subbands of the first part of the CSI report have a higher priority than the odd-numbered subbands. For example, assuming there are two CSI reports, CSI report 1 and CSI report 2, and each CSI report includes three CSI parts (three CSI sub-groups), denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3, then for CSI report 1, the even-numbered subbands of Part 2 CSI in CSI sub-group1 have the highest priority, followed by the even-numbered subbands of Part 2 CSI in CSI sub-group2, and then the CSI part 2 of CSI report 1. The highest priority is given to Part 2 CSI of even-numbered subbands in sub-group 3, followed by Part 2 CSI of odd-numbered subbands in CSI sub-group 1 of CSI report 1. Next, the highest priority is given to Part 2 CSI of odd-numbered subbands in CSI sub-group 2 of CSI report 1, and then Part 2 CSI of odd-numbered subbands in CSI sub-group 3 of CSI report 1. For the same CSI report 1, Part 2 CSI of even-numbered subbands in a CSI sub-group has a higher priority than Part 2 CSI of odd-numbered subbands in the same CSI sub-group. For CSI report 2, the third priority is determined in a similar manner to that of CSI report 1.

[0356]

[0357] This example has the following advantages:

[0358] (1) The first information includes N CSI parts, i.e. N CSI sub-groups. The second information in the CSI report is discarded according to the first method. The second information is a part of the first information or the first information.

[0359] Specifically, based on the CRIs contained in the CSI report, or the CSI reference signal resources corresponding to the CSI report, or the arrangement order or corresponding order of the CRIs contained in the CSI report in the CSI report, or the arrangement order or corresponding order of the CRIs contained in the CSI report in the uplink control information bit sequence, or the third priority, the second information in the CSI report is discarded.

[0360] Example 2

[0361] In the case where a CSI report includes first information, the second information in the CSI report is discarded according to the second method. The first information includes N third information items; the N third information items are N CSI parts, N fourth information items, or N fifth information items. The fourth information items are CRI and their corresponding CSI information, the fifth information items are CSI information corresponding to CSI reference signal resources, N is an integer greater than or equal to 1, and the second information is a part of the first information, or the first information itself.

[0362] Here, N CSI parts can refer to N CSI subgroups, where each CSI subgroup includes 0 or 1 CRI.

[0363] Here, N fourth pieces of information can refer to N sets of information, namely N CRIs and their corresponding CSI information. Each set of information includes CRIs and their corresponding CSI information, specifically 1 CRI, 1 RI, 1 PMI, 1 or 2 CQIs, etc.

[0364] Here, N pieces of fifth information can refer to N sets of information, that is, the CSI information corresponding to N CSI reference signal resources. Each set of information includes the CSI information corresponding to the CSI reference signal resources, specifically 0 or 1 CRI, 1 RI, 1 PMI, 1 or 2 CQI, etc.

[0365] The following example illustrates the process of discarding the second information in a CSI report according to the second method, using the first information as an example, which includes N CSI parts.

[0366] Here, the method of discarding the second information in the CSI report according to the second approach includes:

[0367] The first part of the CSI report is discarded according to the fourth priority.

[0368] The fourth priority is determined in the following order:

[0369] For multiple CSI reports, the broadband CSIs included in the first part of each CSI report have the same priority and the highest priority;

[0370] For multiple CSI reports, if the number of the CSI report is smaller and the number of the CSI section is smaller, then the first part of the CSI report has a higher priority.

[0371] Wherein, if the CSI reports have the same number and the CSI parts have the same number, then the even-numbered subband CSIs included in the first part of the CSI report have a higher priority than the odd-numbered subband CSIs included in the first part of the CSI report; if the CSI reports have the same number and the number of the first CSI part is less than the number of the second CSI part, then the odd-numbered subband CSIs included in the first CSI part have a higher priority than the even-numbered subband CSIs included in the second CSI part; the first CSI part and the second CSI part are different.

[0372] Here, the CSI report includes N CSI parts, or N CSI subgroups.

[0373] Here, the statement that for multiple CSI reports, the broadband CSIs contained in the first part of each CSI report have the same priority and the highest priority can mean that the broadband CSIs in all CSI subgroups have the same priority.

[0374] Here, the priority of the even-numbered subbands of CSI included in the first part of the CSI report may refer to the priority of Part 2 of the CSI in the even-numbered subbands of the CSI subgroup of the CSI report.

[0375] Here, the priority of the odd-numbered subband CSIs included in the first part of the CSI report may refer to the priority of Part 2 CSI of the odd-numbered subbands in the CSI subgroup of the CSI report.

[0376] Here, the first CSI part can refer to the first CSI sub-group among N CSI sub-groups; the second CSI part can refer to the second CSI sub-group among N CSI sub-groups; the number of the first CSI sub-group is less than the number of the second CSI sub-group.

[0377] Furthermore, the step of discarding the first portion of the CSI report according to the fourth priority may include:

[0378] The lower the fourth priority of the first part of CSI, the higher the priority for discarding; conversely, the higher the fourth priority of the first part of CSI, the higher the priority for retention.

[0379] Table 3 illustrates the fourth priority level. As shown in Table 3, assume there are N... REP One CSI report, N REP A CSI report consists of N CSI subgroups, where N is an integer greater than or equal to 1. The fourth priority is determined in the following order: first, for N... REP For each CSI report, all broadband CSIs within a CSI subgroup have the same and highest priority. For example, suppose there are two CSI reports, denoted as CSI report 1 and CSI report 2. Each CSI report includes three CSI parts, or three CSI subgroups, denoted as CSI subgroup1, CSI subgroup2, and CSI subgroup3. In this case, all broadband CSIs within a CSI subgroup have the same and highest priority. The next priority is for N... REPFor a given CSI report, the smaller the CSI report number and the smaller the CSI section number, the higher the priority of the CSI sub-group of the CSI report. Specifically, if the CSI report numbers and CSI section numbers are the same, the even-numbered subbands of CSIs included in the first part of the CSI report have a higher priority than the odd-numbered subbands of CSIs included in the first part of the CSI report. If the CSI report numbers are the same and the number of the first CSI section is smaller than the number of the second CSI section, the odd-numbered subbands of CSIs included in the first CSI section have a higher priority than the even-numbered subbands of CSIs included in the second CSI section. For example, assuming there are two CSI reports, denoted as CSI report 1 and CSI report 2, and each CSI report includes three CSI sections, i.e., three CSI sub-groups, denoted as CSI sub-group1, CSI sub-group2, and CSI sub-group3, then for CSI report 1, the CSI subgroup of CSI report 1 has a higher priority than the odd-numbered subbands of CSIs included in the second CSI report. The priority of CSI Part 2 (CSI 2CSI) in even-numbered subbands of CSI Report 1 is higher than that of Part 2CSI in odd-numbered subbands of CSI Report 1. Next, the priority of Part 2CSI in even-numbered subbands of CSI Report 1 is higher than that of Part 2CSI in odd-numbered subbands of CSI Report 1. Finally, the priority of Part 2CSI in even-numbered subbands of CSI Report 1 is higher than that of Part 2CSI in odd-numbered subbands of CSI Report 1. For CSI Report 2, the determination of the fourth priority is similar to that of CSI Report 1.

[0385]

[0386] Here, if the downlink channel has strong frequency selectivity and the differences between the measured N CSI subgroups are small, such as the RI / PMI contained in each of the N CSI subgroups having a large overlap, or the CQI contained are similar, then the frequency band-priority CSI dropping method can be selected.

[0387] This example has the following advantages:

[0388] (1) The first information includes N CSI parts, i.e. N CSI sub-groups. The second information in the CSI report is discarded according to the second method. The second information is a part of the first information or the first information.

[0389] Specifically, based on the fourth priority, the second piece of information in the CSI report is discarded.

[0390] Example 3

[0391] In the case where a CSI report includes first information, the second information in the CSI report is discarded according to the priority of the N third information items. The first information includes N third information items; the N third information items are N CSI parts, N fourth information items, or N fifth information items. The fourth information is the CRI and its corresponding CSI information, the fifth information is the CSI information corresponding to the CSI reference signal resource, N is an integer greater than or equal to 1, and the second information is a part of the first information or the first information itself.

[0392] Here, N CSI parts can refer to N CSI subgroups, where each CSI subgroup includes 0 or 1 CRI.

[0393] Here, N pieces of fourth information can refer to N sets of information, namely N CRIs and their corresponding CSI information.

[0394] Each set of information includes CRI and corresponding CSI information, specifically one CRI, one RI, one PMI, one or two CQIs, etc.

[0395] Here, N pieces of fifth information can refer to N sets of information, that is, the CSI information corresponding to N CSI reference signal resources. Each set of information includes the CSI information corresponding to the CSI reference signal resources, specifically 0 or 1 CRI, 1 RI, 1 PMI, 1 or 2 CQI, etc.

[0396] The following example illustrates the process of discarding the second information in the CSI report according to the priority of the N third information items, using the first information as an example.

[0397] Here, the priority of the N third pieces of information is determined in the following ways:

[0398] Determine at least one of the following parameters: a first parameter, a second parameter, a third parameter, a fourth parameter, a fifth parameter, and a sixth parameter; wherein, the first parameter represents the identifier associated with the CSI portion, or the identifier of the CRI, or the value of the CRI, or the relative position identifier of the CRI, or the relative position identifier of the CSI portion; the second parameter represents the maximum number of CSIs configured by the higher layer, or the maximum number of CRIs that can be supported, or the maximum number of CSIs that can be supported per CSI report, or the maximum number of CSIs that can be supported corresponding to the maximum number of CSI reference signal resources; the third parameter represents the CSI report type; the fourth parameter represents the CSI type carried in the CSI report; the fifth parameter represents the serving cell index; and the sixth parameter represents the CSI report configuration identifier.

[0399] The priority of the N pieces of third information is determined based on at least one of the first parameter, the second parameter, the third parameter, the fourth parameter, the fifth parameter, and the sixth parameter;

[0400] The determination of the priority of the N third pieces of information includes one of the following:

[0401] Determine the priority of each of the N CSI sections;

[0402] Determine the priority of each of the N pieces of fourth information;

[0403] Determine the priority of each of the N pieces of fifth information.

[0404] Here, discarding the second information in the CSI report according to the priority of the N third information pieces includes:

[0405] According to the priority of the N CSI sections, the CSI sections in the CSI report are discarded;

[0406] or,

[0407] According to the priority of the N fourth pieces of information, the CRI and the corresponding CSI information in the CSI report are discarded;

[0408] or,

[0409] According to the priority of the N fifth pieces of information, the CSI information corresponding to the N CSI reference signal resources in the CSI report is discarded.

[0410] Here, a priority formula is defined for the N CSI sections (N CSI sub-groups) in a CSI report, with each CSI sub-group having an independent priority. This priority calculation formula must be derived from at least the sub-group ID, CRI ID, or CRI contained within the CSI sub-group.

[0411] Here, taking the determination of the priority of one CSI part out of N CSI parts as an example, the priority of that CSI part is calculated according to the following formula, as follows:

[0412] Pri CSIGroup_i (y,k,c,s,x)=2×Ncells×Ms×N×y+Ncells×Ms×N×k+Ms×N×c+N×s+x

[0413] in,

[0414] Pri CSIGroup_i (y,k,c,s,x) represents the priority of the i-th CSI part out of N CSI parts, where i ranges from 1 to N, and N is an integer greater than or equal to 1;

[0415] Ncells represents the value of the high-level parameter maxNrofServingCells;

[0416] Ms is the value of the high-level parameter maxNrofCSI-ReportConfigurations;

[0417] x is the first parameter, which represents the identifier associated with the CSI part, or the identifier of the CRI, or the value of the CRI, or the relative position identifier of the CRI, or the relative position identifier of the CSI part. That is, it is the sub-group ID contained in or associated with the CSI sub-group, or the CRI ID, or the value of the CRI, or the relative position identifier of the CRI, or the relative position identifier of the CSI part.

[0418] The CRI ID definition can be one of the following:

[0419] Definition 1: There are N CRIs in N CSI subgroups. After sorting the N CRIs in ascending order, the ID of the x-th smallest CRI is x, where x = 0, ..., N-1, and N is an integer greater than 1.

[0420] Definition 2: The CRI ID corresponding to the x-th CRI in the uplink control information (UCI) bit sequence is defined as x, or the CRI ID corresponding to the x-th CSI sub-group is defined as x, where x = 0, ..., N-1.

[0421] The relative position identifier of the CRI can be determined according to the order of the CRI in the uplink control information (UCI) bit sequence. For example, if the CRI is the first in the uplink control information (UCI) bit sequence, then the relative position identifier of the CRI can be 0 or 1.

[0422] The relative position identifier of the CSI part can be determined according to the arrangement order of the CSI part among the N CSI parts. For example, if the CSI part is the first in the arrangement order among the N CSI parts, then the relative position identifier of the CSI part is 0 or 1.

[0423] N is the second parameter, which represents the maximum number of CSIs configured by the higher layer (maximum number of CSI subgroups) or the maximum number of CRI reports that can be supported, or the maximum number of CSIs that each CSI report can support or the maximum number of CRI reports that can be supported or the maximum number of CSI reports corresponding to the maximum number of CSI reference signal resources that can be supported.

[0424] y is a third parameter that characterizes the CSI report type. Specifically, for a non-periodic CSI report carried on PUSCH, y = 0; for a semi-persistent CSI report carried on PUSCH, y = 1; for a semi-persistent CSI report carried on PUCCH, y = 2; and for a periodic CSI report carried on PUCCH, y = 3.

[0425] k is the fourth parameter, which represents the type of CSI carried in the CSI report. Specifically, for a CSI report carrying L1-RSRP or L1-SINR, k = 0; for a CSI report not carrying L1-RSRP or L1-SINR, k = 1.

[0426] c is the fifth parameter, which is the serving cell index, i.e., the serving cell index configured in the higher-layer signaling.

[0427] s is the sixth parameter, which represents the CSI report configuration identifier, namely the reportConfigID of the higher-level signaling configuration.

[0428] Here, according to the above formula, if we calculate the Pri corresponding to CSI sub-group #1 CSIGroup_#1 (y,k,c,s,x) is less than the Pri corresponding to CSI sub-group #2 CSIGroup_#2 If (y,k,c,s,x), then the priority of CSI sub-group #1 is higher than that of CSI sub-group #2.

[0429] In other words, determining the priority of each of the N CSI parts can include:

[0430] Multiply the second parameter and the third parameter to obtain the first value;

[0431] The second value is obtained by multiplying the second parameter and the fourth parameter.

[0432] The third value is obtained by multiplying the second parameter and the fifth parameter.

[0433] The product of the second parameter and the sixth parameter is used to obtain the fourth value;

[0434] Based on the first value, the second value, the third value, the fourth value, and the value of the first parameter, the fifth value is obtained;

[0435] The fifth value is used as the priority for each of the N CSI parts.

[0436] It should be noted that the process of calculating the priority of each fourth or fifth piece of information is similar to the process of calculating the priority of each CSI section, and will not be repeated here.

[0437] In practical application, if K CSI reports contain M pieces of third information, the second information in the CSI reports is discarded according to the priority of the M pieces of third information.

[0438] Wherein, K and M are both integers greater than or equal to 1; the M third pieces of information are M CSI parts, M fourth pieces of information, or M fifth pieces of information;

[0439] The priority of the M pieces of third information is determined in the following order:

[0440] For the M third pieces of information, the broadband CSI contained in each third piece of information has the same priority and the highest priority;

[0441] For M pieces of third information, if the priority of the third information is higher, then the priority of the even-numbered subband CSIs contained in the third information is higher, and the priority of the odd-numbered subband CSIs contained in the third information is higher; wherein, for the same piece of third information, the priority of the even-numbered subband CSIs contained in the third information is higher than the priority of the odd-numbered subband CSIs contained in the third information.

[0442] Here, taking M third pieces of information as M CSI parts, i.e. M CSI subgroups, as an example, the priority of the broadband CSIs contained in each third piece of information is the same and the highest priority can mean that the priority of broadband CSIs in all CSI subgroups is the same.

[0443] Here, the priority of the third information can be determined based on at least one of the first parameter, the second parameter, the third parameter, the fourth parameter, the fifth parameter, and the sixth parameter.

[0444] Furthermore, discarding the second information in the CSI report according to the priority of the M pieces of third information may include:

[0445] The lower the priority, the more likely it is to be discarded; conversely, the higher the priority, the more likely it is to be retained.

[0446] Table 4 illustrates the priorities of M third-party information reports. As shown in Table 4, assuming there are K CSI reports, and each CSI report includes N CSI parts (i.e., N CSI sub-groups), where K and N are integers greater than or equal to 1, there are a total of K × N = M CSI sub-groups. Priority 0 is the highest priority, and Priority 2M is the lowest priority. CSI sub-group m is the m-th smallest priority value among the M CSI sub-groups. The priorities of the M CSI sub-groups are determined in the following order: First, for each of the M CSI sub-groups, the broadband CSIs contained in Part 2 of each CSI sub-group have the same and highest priority. For example, assuming there are M = 3 CSI sub-groups, then the broadband CSIs contained in all CSI sub-groups have the same and highest priority. Second, for each of the M CSI sub-groups, the higher the priority of the CSI sub-group, the higher the priority of the CSI sub-group. The higher the priority of CSIs in even-numbered subbands within a subgroup, the higher the priority of CSIs in odd-numbered subbands within a CSI subgroup. However, within the same CSI subgroup, the priority of CSIs in even-numbered subbands is higher than that of CSIs in odd-numbered subbands. For example, assuming there are M = 3 CSI subgroups, denoted as CSI subgroup1, CSI subgroup2, and CSI subgroup3, if CSI subgroup1 has the highest priority, followed by CSI subgroup2, and then CSI subgroup3 has the lowest priority, then the priority of CSIs in even-numbered subbands within CSI subgroup1 is the highest, and the priority of CSIs in even-numbered subbands within CSI subgroup1 is higher than that of CSIs in odd-numbered subbands within CSI subgroup1. Next, the priority of CSIs in even-numbered subbands within CSI subgroup2 is lower, and so on. The even-numbered subbands of CSI in sub-group2 have a higher priority than the odd-numbered subbands of CSI in sub-group2. Next, the even-numbered subbands of CSI in sub-group3 have the lowest priority, and the even-numbered subbands of CSI in sub-group3 have a higher priority than the odd-numbered subbands of CSI in sub-group3.

[0451] Example 4

[0452] Considering that the terminal can use measured channel characteristics, such as downlink channel frequency selectivity, beam differences between multiple measurement resources, and CQI differences, to determine whether a particular discarding method is more suitable for its channel characteristics, the terminal decides which discarding method to use, i.e., the terminal sends the CSI report to the network device; the CSI report includes an indication field; the indication field is used to indicate the method used to discard the second information in the CSI report.

[0453] For example, assuming the indication field occupies 1 bit, when the codepoint of the indication field is 0, it means that the second information in the CSI report is discarded in the first way; when the codepoint of the indication field is 1, it means that the second information in the CSI report is discarded in the second way.

[0454] For example, assuming the indication field occupies 2 bits, when the codepoint of the indication field is 00, it means that the second information in the CSI report is discarded in the first way; when the codepoint of the indication field is 01, it means that the second information in the CSI report is discarded in the second way; when the codepoint of the indication field is 10, it means that the second information in the CSI report is discarded according to the priority of N third information.

[0455] To implement the information processing method of this application embodiment, this application embodiment also provides an information processing device, which is installed in a terminal. Figure 4 This is a schematic diagram of the composition structure of the information processing device according to an embodiment of this application, as shown below. Figure 4 As shown, the device includes:

[0456] Processing module 41 is configured to discard second information in a CSI report if the report includes first information; the second information is a part of the first information or the first information; wherein the first information includes N third information pieces; the N third information pieces are N CSI part fourth information pieces or N fifth information pieces; the fourth information is a Channel State Information Reference Signal Resource Indicator (CRI) and the corresponding CSI information, and the fifth information is the CSI information corresponding to the CSI Reference Signal Resource; N is an integer greater than or equal to 1.

[0457] The method of discarding the second information in the CSI report includes one of the following: discarding the second information in the CSI report according to a first method; discarding the second information in the CSI report according to a second method; the second method being different from the first method; or discarding the second information in the CSI report according to the priority of the N third information items.

[0458] In some embodiments, the processing module 41 is specifically used for:

[0459] Based on the CRI contained in the CSI report or the CSI reference signal resource corresponding to the CSI report, determine the first priority of the first part of the CSI in the CSI report;

[0460] According to the first priority, the first part of the CSI report is discarded.

[0461] In some embodiments, the method for determining the first priority includes:
