Abstract: A method performed by a user equipment (UE) in a wireless communication system is provided. The method comprises receiving configuration information on a multicast broadcast service (MBS), and receiving, based on the configuration information, MBS data in a radio resource control (RRC)_Connected mode. The MBS data is transmitted to plurality of UEs including the UE for multicast transmission, or to the UE for unicast transmission. A Hybrid Automatic Repeat and request (HARQ) retransmission is applied to a transmission of the MBS data.

Abstract: Methods and apparatuses are provided in a wireless communication system. A radio link control (RLC) protocol data unit (PDU) is obtained from a lower layer. A status PDU is generated based on the RLC PDU. The status PDU includes a first field indicating a sequence number (SN) of an RLC data unit identified as lost, a second field indicating a number of consecutively lost RLC data units starting from and including the SN, and a third field indicating whether the second field follows the first first field. The status PDU is delivered to the lower layer.
