Abstract: The present disclosure relates to a communication system and technique that may be applied to intelligent services based on a 5G communication technology and an IoT-related technology. The present disclosure provides a method for data transmission of a terminal in a wireless communication system that includes inputting a packet data convergence protocol packet data unit (PDCP PDU) output from a PDCP entity to a first radio link control (RLC) entity and a second RLC entity. The method also includes inputting a first radio link control packet data unit (RLC PDU) output from the first RLC entity and a second RLC PDU output from the second RLC entity to a medium access control (MAC) entity and transmitting a medium access control packet data unit (MAC PDU) output from the MAC entity through a first physical layer (PHY) entity and a second physical layer entity.

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: A communication method and system for converging a 5th generation (5G) communication system for supporting higher data rates beyond a 4th generation (4G) system with a technology for Internet of things (IoT) are provided. The communication method and system include intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method, a terminal, and a base station for paging and SI update transmission and reception in a wireless communication system are provided. The method includes receiving, from a base station, information on a default discontinuous reception (DRX) cycle, identifying a UE specific DRX cycle, identifying whether an indicator indicating that the UE monitors a paging occasion (PO) based on the UE specific DRX cycle is configured, identifying whether the UE specific DRX cycle is greater than the default DRX cycle, identifying a first paging frame (PF) for monitoring a paging message and a second PF for monitoring a short message in case that the indicator is configured and the UE specific DRX cycle is greater than the default DRX cycle, identifying a first PO corresponding to the first PF and a second PO corresponding to the second PF, and monitoring a physical downlink control channel (PDCCH) addressed to a paging-radio network temporary identity (P-RNTI) in the identified first and second POs.
