1. A method for wireless communication, comprising:
receiving multicast traffic at a network device for delivery to a plurality of user equipments (UEs);
determining, at the network device, whether to deliver the multicast traffic to the plurality of UEs via unicast delivery, via multicast delivery, or combinations thereof;
generating a multicast radio network temporary identifier (M-RNTI) that identifies a source of the multicast traffic;
transmitting a signal to each UE within at least a subset of the plurality of UEs that provides each UE within the subset of the plurality of UEs with a tuple based at least in part on the M-RNTI; and
transmitting the multicast traffic to the plurality of UEs based at least in part on the determining, wherein transmitting the multicast traffic to the plurality of UEs comprises:
transmitting the multicast traffic to each UE within at least the subset of the plurality of UEs via a shared multicast radio bearer (MRB), the shared MRB identified by at least the M-RNTI associated with the source of the multicast traffic.
