Abstract
According to one embodiment of the present invention, a method by which a first wireless device receives a reference signal for distance measurement in a wireless communication system can comprise the steps of: receiving, from a second wireless device, a first reference signal including a first sinusoidal signal having a first angular frequency and a second sinusoidal signal having a second angular frequency; performing fast Fourier transform (FFT) on the first reference signal; acquiring a phase difference between the first sinusoidal signal and the second sinusoidal signal on the basis of the FFT result; and transmitting, to the second wireless device, a second reference signal for the distance measurement and a third reference signal indicating information on the phase difference. The first wireless device is capable of communicating with at least one of another wireless device, a wireless device related to an autonomous driving vehicle, a base station or a network.
