Abstract

A terminal device receives first indication information indicating first precoding information and second precoding information. The terminal device determines a first group of power control parameters corresponding to the first precoding information and determines a second group of power control parameters corresponding to the second precoding information. The terminal device determines first transmit power based on the first group of power control parameters and sends a first PUSCH repetition based on the first transmit power and the first precoding information, and determines second transmit power based on the second group of power control parameters and sends a second PUSCH repetition based on the second transmit power and the second precoding information.

Claims (36)
