Abstract
A method for a first wireless device receiving a reference signal for measuring a distance in a wireless communication system, according to one embodiment of the present invention, may comprise the steps of: receiving, from a second wireless device, a first reference signal comprising a first sinusoidal signal having a first angular frequency and a first initial phase value, and a second sinusoidal signal having a second angular frequency and a second initial phase value; acquiring the phase difference between the first sinusoidal signal and the second sinusoidal signal on the basis of a fast Fourier transform (FFT) performed on the first reference signal; correcting the phase difference on the basis of the first initial phase value and the second initial phase value; and transmitting, to the second wireless device, a second reference signal for measuring a distance, and a third reference signal representing information on the corrected phase difference.
