Method for tracking phase noise in wireless communication system, and apparatus therefor

Provided are a method and an apparatus for performing phase tracking by a terminal in a wireless communication system. The present invention may provide a method and an apparatus for performing phase tracking, the method comprising the steps of: receiving at least one parameter from a base station, wherein the at least one parameter indicates locations of frequency tones and symbols in a specific resource area to which at least one first reference signal is mapped; receiving the at least one first reference signal used for phase tracking from the base station through the specific resource area, wherein the at least one first reference signal is mapped to a specific symbol in a time domain and a specific frequency tone in a frequency domain, the specific symbol and the specific frequency tone being different for each antenna port through which the first reference signal is transmitted; and performing the phase tracking on the basis of the at least one first reference signal.
