Abstract: An in-device coexistence interference report control method of a network for terminal to inform the network of interference among heterogeneous radio communication modules coexisting in the terminal is provided. The method includes determining, at a terminal when a terminal capability enquiry message is received from a base station, whether the base station supports an In-Device Coexistence (IDC) interference report, transmitting, when the IDC interference report is supported, a terminal capacity information message to the base station, receiving a Radio Resource Control (RRC) connection reconfiguration message including information on whether terminal's IDC interference indicator transmission is permitted from the base station; and transmitting an RRC connection reconfiguration complete message to the base station in response to the RRC connection reconfiguration message. The in-device coexistence interference indication control method is advantageous in preventing the UE from transmitting useless in-device coexistence interference indication messages, resulting in reduction of unnecessary signaling.

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.

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.
