Abstract

Embodiments include systems and methods for supporting for supporting retransmission in a multicast session in a Fifth Generation (5G) New Radio (NR) (5G NR) radio access network (RAN). Various embodiments may provide an enhanced multicast radio bearer (MRB) architecture leveraging Packet Data Convergence Protocol (PDCP) status reporting by wireless devices to a base station of a 5G NR RAN. Various embodiments may support multiple Radio Link Control (RLC) entities, also referred to as RLC legs, in a multicast session. One or more multicast RLC legs may be used for multicast and/or unicast transmission to wireless devices and a unicast RLC leg may be used for unicast transmission to a specific wireless device. Various embodiments may enable PDCP level retransmission of PDCP protocol data units (PDUs).
