1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving configuration information on a multicast broadcast service (MBS); and
receiving, based on the configuration information, the MBS in a radio resource control (RRC) connected mode,
wherein the MBS is received via a multicast bearer for the MBS,
wherein the multicast bearer for the MBS is associated with a service data adaptation protocol (SDAP) entity and a packet data convergence protocol (PDCP) entity,
wherein the PDCP entity is associated with a radio link control (RLC) acknowledged mode (AM) entity and an RLC unacknowledged mode (UM) entity,
wherein a hybrid automatic repeat request (HARQ) retransmission is applied to data received via the multicast bearer for the MBS, and
wherein the PDCP entity provides a PDCP reordering function.
