Abstract: According to at least one of embodiments disclosed in the application, a method of receiving a signal by a device in a wireless communication system, may comprise receiving a time-domain signal including one or more orthogonal frequency divisional multiplexing (OFDM) symbols; and obtaining a frequency-domain signal by performing a fast Fourier transform (FFT) based on the time-domain signal, wherein each OFDM symbol in the time-domain signal may include a data part, a cyclic prefix (CP) part, and a time domain reference signal (TDRS) part, wherein the TDRS part may include a known sequence that is predefined for phase noise compensation in a time-domain, and wherein the phase noise compensation can be performed in a symbol level in the time-domain based on the TDRS part in each OFDM symbol.
