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: The disclosure relates to a 5G or pre-5G communication system. A method performed by a terminal includes receiving, from a base station, first system information including information indicating that an extended DRX mode is allowed in a cell; transmitting, to an entity for managing mobility of the terminal, a request message including first information on a first DRX cycle for an operation in the extended DRX mode; receiving, from the entity, a response message based on the request message; identifying whether the response message includes second information on a second DRX cycle for the operation in the extended DRX mode; performing the operation in the extended DRX mode based on the second information, when the response message includes the second information; and performing an operation in a regular DRX mode based on third information on a default cycle, when the response message does not include the second information.
