Abstract
A Relay node may detect conflicts regarding media access control (MAC) addresses. A relay node may receive a request to establish a link with a source node. The relay node may receive the MAC address of the source node. The relay node may detect a conflict associated with the MAC address of the source node. The relay node may reject the request to establish the link with the source node.
Claims14
A first wireless transmit/receive unit (WTRU) comprising:
- a transceiver;
- and
- a processor configured to:
- receive, via the transceiver, a direct communication request (DCR) message from 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 second WTRU and the first WTRU;
- send, via the transceiver, a direct security mode (DSM) command message to the second WTRU;
- receive, via the transceiver, a first response message from the second WTRU, wherein the first response message comprises an indication of a medium access control (MAC) address associated with the second WTRU;
- send, via the transceiver, a direct communication (DC) reject message to the second WTRU, wherein the DC reject message comprises a cause code indicating that the MAC address of the second WTRU is not unique;
- and
- receive a link modification request message from the second WTRU, wherein the a link modification request message comprises an indication of a second MAC address of the second WTRU.
5-6. (canceled)
A method performed by a first wireless transmit/receive unit (WTRU), the method comprising:
- receiving a direct communication request (DCR) message from 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 second WTRU and the second WTRU;
- sending a direct security mode (DSM) command message to the second WTRU;
- receiving a first response message from the second WTRU, wherein the first response message comprises an indication of a medium access control (MAC) address associated with the second WTRU;
- sending a direct communication (DC) reject message to the second WTRU, wherein the DC reject message comprises a cause code indicating that the MAC address of the second WTRU is not unique;
- and
- receiving a link modification request message from the second WTRU, wherein the link modification request message comprises an indication of a second MAC address of the second WTRU.
