Abstract
Methods and apparatus for Layer-2 forwarding of multicast packets are disclosed. In an example, a method implemented in a wireless transmit/receive unit (WTRU) for wireless communications includes receiving a first packet comprising a request for content available at the WTRU, determining at least one outstanding request for the same content, and determining multicast path information of the at least one outstanding request. The method further includes generating a second packet and setting a destination Medium Access Control (MAC) address to a broadcast (BC) MAC address in the second packet, adding a proxy rule identifier (PRID) corresponding to the request into a payload of the second packet, and forwarding the second packet to another WTRU.
