Abstract
A method whereby a user equipment transmits/receives a reference signal for distance measurement in a wireless communication system according to an embodiment of the present invention comprises: a step of receiving from a base station a downlink (DL) positioning reference signal (PRS) including sinusoidal components of different angular frequencies; a step of acquiring a phase difference between the sinusoidal components of the DL PRS; a step of transmitting a first uplink (UL) PRS indicating the phase difference so as to measure a first distance between the user equipment and the base station at a first point of time; and a step of transmitting a second UL PRS so as to measure a second distance between the user equipment the position of which has changed after the first point of time and the base station wherein the user equipment may configure the same phase difference acquired via the DL PRS before the first point of time for the second UL PRS without receiving an additional DL PRS for measuring the second distance.
