METHOD FOR MEASURING DISTANCE BETWEEN DEVICES VIA DIRECT DEVICE-TO-DEVICE COMMUNICATION IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR

摘要

Disclosed is a method for transmitting, by a device, a signal for direct device-to-device communication in a wireless communication system. Specifically, the method comprises the steps of: receiving a downlink subframe from a reference base station; transmitting a first signal to a counterpart device on the basis of the boundary of the downlink subframe; and transmitting a second signal to the counterpart device prior to the boundary of the downlink subframe by a predetermined offset.
