Abstract: A method of transmitting, by a terminal, a phase noise compensation reference signal in a wireless communication system is discussed. The method includes determining a frequency resource and a time resource of a demodulation reference signal (DM-RS); mapping the phase noise compensation reference signal to a frequency resource and a time resource based on the determined frequency resource and the time resource of the DM-RS; and transmitting, to a base station, the phase noise compensation reference signal on the mapped frequency resource and the time resource of the phase compensation reference signal. Further, a location of a phase noise compensation reference signal symbol in the time resource is determined based on a location of a DM-RS symbol in the time resource of the DM-RS.
