Document Type and Number:
WIPO Patent Application WO/2018/225936
Kind Code:
A1
Abstract:
The present invention relates to a method and a device for a terminal performing phase tracking in a wireless communication system. According to the present invention, a method and a device may be provided, the method comprising: receiving, from a base station, configuration information associated with a phase tracking reference signal (PTRS); and on the basis of the configuration information, receiving a first demodulation reference signal (DMRS) and the PTRS, wherein the PTRS is mapped to at least one OFDM symbol according to a particular pattern and at a predetermined symbol interval, and phase tracking for data demodulation is performed on the basis of at least one of the first DMRS or the PTRS.
