Abstract: A method for communicating a relay user equipment (UE) for a device to device (D2D) link at a UE in a wireless communication system is disclosed. The method includes steps of receiving, from the relay UE, information on an identifier of a second cell connected with the relay UE; transmitting, to a first cell connected with the UE, an assistance message including information that an identifier of the first cell is different from the identifier of the second cell; receiving, from the first cell, a resource allocation message including resource information for a communication via the relay UE; and performing the communication via the relay UE based on the resource information.
