Title:
METHOD AND DEVICE FOR TRANSMITTING REFERENCE SIGNAL
Document Type and Number:
WIPO Patent Application WO/2019/095828
Kind Code:
A1
Abstract:
The present application provides a method and a device for transmitting a reference signal. The transmission method comprises: a network device determining, according to information of a phase tracking reference signal (PTRS) of a terminal device, an identifier of the terminal device, and a first bandwidth, the resource block offset of a frequency domain location of the PTRS of the terminal device, wherein information of the PTRS comprises the frequency domain density or the frequency domain interval of the PTRS, and the first bandwidth is the bandwidth scheduled by the network device for the terminal device; and the network device transmitting the PTRS by the terminal device according to the resource block offset of the frequency domain location of the PTRS. The method for transmitting a reference signal provided by embodiments of the present application facilitates interference randomization of a PTRS.
