AI Technical Summary
Technical Problem
In the uplink transmission of a terminal in full-duplex mode, it may interfere with the downlink transmission of other terminals, affecting communication performance.
Method used
The first terminal determines the uplink precoding based on the channel information between itself and other terminals, and uses the precoding to transmit the physical uplink shared channel during uplink transmission, thereby suppressing interference to the downlink transmission of other terminals.
Benefits of technology
It effectively suppressed interference with downlink transmission of other terminals and improved communication performance.

Abstract
The present disclosure relates to an uplink transmission method, a communication device, a communication system, and a storage medium. The method comprises: determining a first precode on the basis of first information and a CSI-RS resource, wherein the first information comprises channel information between a first terminal and a second terminal, and the first precode comprises at least one precode; and sending a PUSCH to a network device on the basis of a second precode in the first precode, wherein the second precode comprises at least one precode. In the method of the present disclosure, in non-codebook-based uplink transmission, the first terminal determines an uplink precode on the basis of channel information between the first terminal and another terminal, so that on the basis of the determined uplink precode, interference on downlink transmission of the another terminal can be effectively suppressed during uplink transmission, thereby improving communication performance.
