Sidelink data transmission method and related apparatus

Abstract

A first transmitting terminal sends a first channel state information-reference signal CSI-RS in N frequency domain units, where N is a positive integer. The first transmitting terminal detects channel state information CSI sent by K receiving terminals, where the CSI sent by the K receiving terminals is determined based on the first CSI-RS, and K is a positive integer. The first transmitting terminal updates a transmit power of the first transmitting terminal in the N frequency domain units based on the CSI sent by the K receiving terminals. When updated powers of F frequency domain units in the N frequency domain units are greater than a preset threshold, the first transmitting terminal sends user data in at least one of the F frequency domain units, where F is a positive integer less than or equal to N.
