METHOD FOR TRANSMITTING AND RECEIVING PHASE NOISE COMPENSATION REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR

WIPO Patent Application WO/2017/213326

A1

The present specification provides a method for transmitting and receiving a phase noise compensation reference signal (PCRS) in a wireless communication system, which is performed by a terminal, the method comprising the steps of: receiving control information related to transmission of downlink data from a base station; identifying a transmission location of a demodulation reference signal (DM-RS) for demodulating the downlink data, on the basis of the received control information; and receiving the PCRS from the base station through at least one symbol after a symbol for transmission of the DM-RS, by taking into consideration the identified transmission location of the DM-RS.
