METHOD WHEREBY TERMINAL TRANSMITS DEVICE-TO-DEVICE (D2D) SIGNAL IN WIRELESS COMMUNICATION SYSTEM THAT SUPPORTS D2D COMMUNICATION, AND APPARATUS THEREFOR

Document Type and Number:

WIPO Patent Application WO/2019/059649

Kind Code:

A1

Abstract:

Disclosed are a method whereby a terminal transmits a device-to-device (D2D) signal in a wireless communication system that supports D2D communication according to various embodiments, and an apparatus therefor. Disclosed are a method whereby a terminal transmits a D2D signal, and an apparatus therefor, wherein the method comprises: a step of measuring a technology congestion level with regard to a predetermined resource area; and a step of determining a wireless technology that is to be used for the 2D2 signal transmission on the basis of the technology congestion level, and transmitting the D2D signal on the basis of the determined wireless technology, and wherein the technology congestion level is related to the proportion of received signals that include information regarding the usage of a particular wireless technology in the predetermined resource area.
