Abstract: Disclosed is a phase noise compensation method performed by a terminal. The terminal may: receive a signal, wherein the signal is transmitted via multiple symbols; estimate phase noise for each of multiple phase noise estimation sections included in the multiple symbols in the time domain, wherein each of the multiple phase noise estimation sections is included in cyclic prefixes (CPs) included in the respective multiple symbols; and perform the phase noise compensation on the multiple symbols in the time domain on the basis of the estimated phase noise.
