Abstract
This application provides a reference signal indication method and apparatus. The method includes: transmitting, by a terminal device, a phase tracking reference signal (PTRS) to a network device based on a time domain density; and receiving, by the network device, the PTRS transmitted by the terminal device based on the time domain density, where the time domain density is a density in a discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) waveform. Therefore, successful PTRS transmission can be ensured.
