Abstract
Systems, methods, and instrumentalities associated with providing and/or receiving a multicast-broadcast service (MBS) in a wireless communication system are described herein. A network relay may be used to facilitate the provision of the MBS to a remote wireless transmit/receive unit (WTRU). The network relay may request network authorization to join the MBS on behalf of the remote WTRU. The network relay may include an identifier of the remote WTRU and information regarding the multicast group that the remote WTRU desires to join in the authorization request. The network relay may inform the remote WTRU about an authorization response received from the network, and may forward MBS traffic to the remote WTRU if authorization is granted. The network relay may broadcast an MBS relay support indication to one or more remote WTRUs. The network relay may receive a group paging monitor request from a remote WTRU and may monitor group paging messages for the remote WTRU in response.
