Title:
REFERENCE SIGNAL INDICATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/201802
Kind Code:
A1
Abstract:
Provided in the present application are a reference signal indication method and device. The method comprises: a terminal apparatus sending, according to a time-domain density, a PTRS to a network apparatus; and the network apparatus receiving the PTRS sent by the terminal apparatus according to the time-domain density, the time-domain density being a density in a discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) waveform. The present invention ensures successful PTRS transmission.
