It should be noted that when Part 1 of a CSI report is discarded, its corresponding part 2 is also discarded. If Part 1 of a CSI report can be sent, its corresponding Part 2 can be discarded step by step according to the method in the related art.
- the code rate of each CSI part 1 is calculated, and compared with the code rate threshold 1, if it is greater than the code rate threshold 1, the part 1 of the CSI report of the low priority needs to be discarded until The code rate of each CSI part 1 transmitted (or the code rate of all CSI part 1) is lower than the code rate threshold 1;
