Method and device for performing location measurement on basis of PDOA

摘要

Provided is a method by which a terminal performs location measurement on the basis of a PDOA in a wireless communication system, according to one embodiment of the present description, wherein the method, by which a terminal performs location measurement on the basis of PDOA, comprises: a step for receiving, from a base station, a signal through a plurality of paths; a step for acquiring phase difference information on each of the plurality of paths; and a step for reporting, to the base station, the phase difference information on the basis of the reference signal. The terminal is capable of communicating with at least one of another terminal, a terminal related to an autonomous driving vehicle, the base station, or a network.
