1. A wireless transmit/receive unit (WTRU) comprising a processor and memory, storing instructions which, when executed by the processor, cause the WTRU to:
send, to a network, a first message indicating a request to join a multicast group, wherein the message comprises an identifier associated with the multicast group and information associated with a protocol data unit (PDU) session to be used to receive data associated with the multicast group;
receive, from the network, a second message indicating acceptance of the request to join the multicast group; and
receive, via the PDU session, data associated with the multicast group.
