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 transmitted to a plurality of UEs including the UE for multicast transmission, or to the UE for unicast transmission,
wherein a hybrid automatic repeat and request (HARQ) retransmission is applied to a transmission of the MBS,
wherein a service data adaptation protocol (SDAP) entity is configured for a bearer of the MBS, and
wherein a mapping information between a quality of service (QoS) flow and the bearer of the MBS is configured.
