Abstract
A method for estimating a phase noise by a wireless device in a wireless communication system according to an embodiment of the present disclosure comprises the steps of: receiving a pre-configured pilot signal and a phase tracking reference signal (PTRS); calculating a first phase noise on the basis of the pre-configured pilot signal; calculating a common phase error (CPE) on the basis of the phase tracking reference signal (PTRS); and estimating a phase noise (PN) on the basis of the first phase noise and the common phase error (CPE). The PN is estimated through interpolation based on a specific reference point, and the specific reference point is based on the first phase noise and the CPE.
