Method and device for transmitting D2D data in wireless communication system

摘要

A method for transmitting device-to-device (D2D) data in a wireless communication system is provided. A first terminal establishes a D2D link with a second terminal. The first terminal transmits a scheduling request (SR) for an uplink and an SR for the D2D link to a base station. The first terminal receives, from the base station, scheduling information on the D2D link determined on the basis of the SR for the D2D link. The first terminal transmits D2D data to the second terminal on the basis of the scheduling information

1. A method for transmitting device-to-device (D2D) data in a wireless communication system, the method comprising:
establishing, by a first terminal, a D2D link with a second terminal; transmitting, by the first terminal to a base station, a scheduling request (SR) for an uplink and an SR for the D2D link; receiving, by the first terminal from the base station, scheduling information for the D2D link determined on the basis of the SR for the D2D link; and transmitting, by the first terminal to the second terminal, the D2D data on the basis of the scheduling information, wherein the SR for the uplink is transmitted in a first SR transmission-possible subframe; wherein the SR for the D2D link is transmitted in a second SR transmission-possible subframe; and wherein the first SR transmission-possible subframe and the second SR transmission-possible subframe have different periodicities.
