1. A method of device to device direct communication, the method comprising:
receiving, by a user equipment (UE), a plurality of discovery messages on a physical sidelink shared channel (PSSCH) from one or more candidate relay UEs;
measuring, by a physical layer within the UE, power of reference signals associated with resources on which a protocol data unit (PDU) including each discovery message is received;
filtering, by a radio resource control (RRC) layer within the UE, power measurements corresponding to a same relay UE ID among power measurements corresponding to the plurality of discovery messages; and
selecting a relay UE among the one or more candidate relay UEs based on the filtered power measurements.
