Title:
COMMUNICATION METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/125125
Kind Code:
A1
Abstract:
The present application provides a communication method and a communication apparatus, which are used for enabling a network device to indicate to a terminal device different uplink pre-coding information on different resource block (RB) sets, so that performance loss can be avoided to a certain extent to improve communication efficiency. In the method, a terminal device receives first indication information, wherein the first indication information is used for indicating the number of bits occupied by second indication information, the second indication information is used for indicating uplink pre-coding information of P RB sets, each RB set in the P RB sets comprises one or more RBs, the uplink pre-coding information corresponding to different RB sets in the P RB sets is different, and P is greater than or equal to 2; the terminal device receives DCI; the terminal device determines the second indication information in the DCI on the basis of the number of bits; the terminal device sends uplink information on the basis of the uplink pre-coding information of the P RB sets.
