Claim:
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.
