Title: METHOD FOR ESTIMATING DISTANCE BETWEEN D2D TERMINALS AND APPARATUS FOR METHOD IN WIRELESS COMMUNICATION SYSTEM
Abstract:
A method for estimating the distance between device-to-device (D2D) terminals in a wireless communication system according to the present specification, carried out by a first D2D terminal, is characterized by comprising the steps of: receiving, from a second D2D terminal, a particular message comprising first distance information, regarding the differences in distance between the second D2D terminal and at least three reference base stations configured thereby, and second distance information indicating the distances between said at least three reference base stations; measuring the distance to each reference base station; and estimating the distance to the second D2D terminal by means of the measured distance to each reference base station, first distance information and second distance information.
