Abstract

The disclosure relates to a signal transmission method and a device. The signal transmission method includes the following. A terminal device transmits a phase-tracking reference signal (PTRS), where a number of transmission layers associated with a PTRS port is less than or equal to a number of transmission layers of a discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-S-OFDM) waveform physical uplink shared channel (PUSCH), and the number of transmission layers of the DFT-S-OFDM waveform PUSCH is greater than or equal to 2. With embodiments of the disclosure, when transmitting a PTRS, the terminal device can support mapping in multi-layer PUSCH transmission when the number of transmission layers of the DFT-S-OFDM waveform PUSCH is greater than or equal to 2.
