D2D OPERATION METHOD PERFORMED BY MEANS OF TERMINAL IN WIRELESS COMMUNICATION SYSTEM AND TERMINAL USING SAME

摘要

The present invention provides a device-to-device (D2D) operation method performed by means of a terminal in a wireless communication system. In the method, uplink transmission and D2D transmission are determined to be contended or not. If the uplink transmission and the D2D transmission are contended, the D2D transmission is determined to be performed or not. And if the D2D transmission is determined to be performed, the D2D transmission is performed. The D2D transmission is determined to be performed or not on the basis of the priority of the uplink transmission and the priority of the D2D transmission.
