Problems solved by technology

[0006] It can be seen that the reliability of the CSI report is not considered when discarding information at present, and the discarded information may belong to the CSI report with high reliability. Such information may be relatively important, that is to say, the current sorting method may lead to More important information is discarded

Embodiment approach

[0286] Another implementation is introduced below. In this implementation, the first CSI report set and the second CSI report set include at least one of the following:

[0287] The report index of the CSI report included in the first CSI report set is smaller than the report index of the CSI report included in the second CSI report set;

[0288] The CSI report included in the first CSI report set includes wideband CSI, and / or, the CSI report included in the second CSI report set includes subband CSI;

[0289] The CSI report included in the first CSI report set includes CSI part1, and / or, the CSI report included in the second CSI report set includes CSI part2; and,

[0290] The CSI report included in the first CSI report set is carried on the PUCCH, and / or the CSI report included in the second CSI report set is carried on the PUSCH.

[0291] Wherein, the report index of the CSI report included in the first CSI report set is smaller than the report index of the CSI report incl...

example 1

[0403] In the introduction process of Example 1, the first CQI and the second CQI correspond to the first BLER, the third CQI and the fourth CQI correspond to the second BLER, the first CQI and the fourth CQI are wideband CQIs, the second CQI and The third CQI is a subband CQI as an example, and the first BLER is equal to 10e-5, and the second BLER is equal to 10e-3 as an example.

[0404] In addition, in Example 1, the sorting order of CQI in the CSI report is sorted in the order from wideband CQI to subband CQI, in the wideband CQI, it is sorted in ascending order of BLER corresponding to the CQI, and in the order of subband CQI For example, in the band CQI, the BLERs corresponding to the CQI are sorted in descending order. In addition, for the subband CQIs, Example 1 also uses the sequence from the even subband CQIs to the odd subband CQIs as an example.

[0405] The following Table 24-Table 28 are examples of the CSI report carried on the PUCCH.

[0406] When the PMI inc...

example 2

[0436] In the introduction process of Example 2, the first CQI and the second CQI correspond to the first BLER, the third CQI and the fourth CQI correspond to the second BLER, the first CQI and the fourth CQI are wideband CQIs, the second CQI and The third CQI is a subband CQI as an example, and the first BLER is equal to 10e-5, and the second BLER is equal to 10e-3 as an example.

[0437] In addition, in Example 2, the sorting order of CQIs in the CSI report is, for example, sorted according to the order of BLERs corresponding to the CQIs from small to large, and then sorted according to the order from wideband CQI to subband CQI. In addition, for the subband CQIs, the example 2 also uses ordering from even subband CQIs to odd subband CQIs as an example.

[0438] The following Table 31-Table 33 are examples of CSI reports carried on the PUCCH.

[0439] When the PMI includes the subband PMI, or the CQI includes the subband CQI, Table 31 shows the mapping order of the CSI part...

Abstract

A communication method and device for reducing the possibility of important information being discarded. One of the communication methods includes: determining at least two CSI report sets, each CSI report set in the at least two CSI report sets includes at least one CSI report, and the at least two CSI report sets include the first error block The first CSI report set corresponding to the block error rate and the second CSI report set corresponding to the second block error rate; according to the mapping ordering rule, generate the uplink control information bit sequence corresponding to the at least two CSI report sets, and the mapping ordering rule includes The order from the first CSI report set to the second CSI report set.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] The terminal device can obtain a channel state information (channel state information, CSI) report (report) through the channel measurement of the CSI reference resource, and the terminal device encodes the CSI report to obtain the CSI, and can send the CSI to the network device, then the network device can Scheduling data for the terminal device according to the received CSI. It can be seen that the more timely the terminal device sends the CSI to the network device, the more accurate the allocation of resources by the network device can be, thereby improving the utilization efficiency of system resources. [0003] Before encoding the CSI reports, the terminal device needs to sort the CSI reports. At present, the terminal device sorts the CSI reports according to the index of the CSI reports in...
