1. A method of performing phase noise compensation by a user equipment (UE) in a wireless communication system, the method comprising:
receiving a data signal and a phase tracking reference signal (PTRS), wherein the data signal is received based on a first numerology and the PTRS is received based on a second numerology;
estimating phase noise based on the PTRS; and
performing the phase noise compensation on the data signal in a time domain based on the estimated phase noise,
wherein a first data region in a first symbol for the first numerology is 2n times longer than a second data region in a second symbol for the second numerology, where n is an integer of 1 or more,
wherein a cyclic prefix (CP) of a third symbol in which the data signal and the PTRS are received is configured based on a sum of the first data region and the second data region,
wherein a frequency length of a third data region in the third symbol is a same as a frequency length of the first data region, and
wherein the third data region is expressed as a sum of the first data region and 2n number of the second data regions in a time domain.
