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, wherein the DCR message initiates establishment of a link between the first WTRU and the second WTRU, wherein the link is for relay traffic between the first WTRU and the second WTRU;
receive, via the transceiver, a direct security mode (DSM) command message from the second WTRU;
send, via the transceiver, a first response message to the second WTRU, wherein the first response message comprises an indication of a medium access control (MAC) address of the first WTRU;
receive, via the transceiver, a direct communication (DC) reject message from the second WTRU, wherein the DC reject message comprises a cause code indicating that the MAC address of the first WTRU is not unique; and
send a link modification message to the second WTRU, wherein the link modification message comprises an indication of a second MAC address of the first WTRU.
