Abstract
A relay node may detect conflicts regarding media access control (MAC) addresses. A source node may send a request to the relay node. The request may be a request to establish communications with a target node. The source may send, to the relay node, an indication of the MAC address of the source node. The source node may receive a reject message from the relay node. The reject message may comprise an indication of a conflict associated with the MAC address of the source node.
Claims12
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 request message to the second WTRU, wherein the link modification request message comprises an indication of a second MAC address of the first WTRU.
5-6. (canceled)
A method performed by a first wireless transmit/receive unit (WTRU), the method comprising:
- sending 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;
- receiving a direct security mode (DSM) command message from the second WTRU;
- sending 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;
- receiving 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
- sending a link modification request message to the second WTRU, wherein the link modification request message comprises an indication of a second MAC address of the first WTRU.
