receiving, from a base station, one or more radio resource control (RRC) messages including one or more first configuration parameters of a MBS radio bearer, one or more second configuration parameters of a first radio link control (RLC) entity associated with the MBS radio bearer, and one or more third configuration parameters of a second RLC entity associated with a unicast service bearer, wherein the first RLC entity and the second RLC entity are associated with a same unicast scheduling for the UE in a medium access control (MAC) entity;
receiving, from the base station, a packet associated with the MBS radio bearer at the first RLC entity, wherein the packet associated with the MBS radio bearer is demultiplexed with a packet associated with the unicast service bearer at the MAC entity;
transmitting, to the base station, a status protocol data unit (PDU) comprising a negative acknowledgement (NACK) in response to the packet associated with the MBS radio bearer not being received; and
receiving the packet associated with the MBS radio bearer retransmitted from the base station at the first RLC entity.
