1. A first wireless transmit/receive unit (WTRU) comprising:
a transceiver; and
a processor configured to:
send, via the transceiver, a direct communication request (DCR) message to a second WTRU;
receive, via the transceiver, a direct communication accept (DCA) message from the second WTRU, wherein the DCA message comprises an indication of a medium access control (MAC) address of the second WTRU;
detect that the MAC address of the second WTRU is not unique;
send, via the transceiver, a link modification (LM) request message to the second WTRU, wherein the LM request message assigns a new MAC address to the second WTRU; and
receive, via the transceiver, an LM response message from the second WTRU, wherein the LM response message acknowledges receipt of the newly assigned MAC address for the second WTRU.
