Method for transmitting and receiving phase noise compensation reference signal in wireless communication system, and apparatus therefor

A user equipment (UE) for transmitting and receiving a phase noise compensation reference signal (PCRS) in a wireless communication system, the UE comprising:

• a radio frequency (RF) unit for transmitting and receiving a radio signal;
• and
• a processor for controlling the RF unit,
• wherein the processor controls to:
• receive, from a base station, control information related to a transmission of a downlink data,
• wherein the control information includes at least one of a precoding scheme related to the downlink data, a number of transmission ranks, or a modulation and coding scheme (MCS) level;
• check a transmission location of a demodulation reference signal (DM-RS) for demodulating the downlink data based on the received control information;
• and
• receive, from the base station, the PCRS on at least one symbol after a transmission symbol of the DM-RS considering the checked transmission location of the DM-RS.
