Abstract: The purpose of the present invention is to provide a method and a device for efficiently supporting multi-link transmission regardless of the type of RAT and the types of protocols. The present invention provides a method for aggregating links in an IP layer, and a method by which a multi-packet gateway transmits a packet comprises: confirming information on a link available for a terminal; scheduling a received data packet on the basis of the information on the available link; and transmitting the data packet, wherein the data packet is distributed so as to be transmitted by using the available link.

Abstract: The general purpose of the present disclosure is to retransmit data between base stations in a wireless communication system, and an operating method of a base station comprises the steps of: receiving, from another base station, information on unreceived packets; and retransmitting at least one unreceived packet among the unreceived packets to another base station based on the received information, wherein the at least one unreceived packet is determined based on a difference value between an identification number of the unreceived packets and an identification number of a last packet transmitted to the other base station.

Abstract: A method and an apparatus for reducing delay in enhanced multimedia broadcast multicast services (eMBMS)-based group communication are provided. The method includes receiving the user packet, including information of a time stamp assigned by a broadcast/multicast service center (BM-SC), from the BM-SC, and transmitting the user packet to a terminal through a physical multicast channel based on information of the time stamp, wherein the time stamp is assigned at an interval set to a value less than a multimedia broadcast multicast services (MBMS) scheduling period.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). An apparatus and an operation method of a base station in a wireless communication system are provided. The method may include performing data communication with a terminal that is in a first sub-state of a radio connection state, and controlling to change the state of the terminal from the first sub-state to a second sub-state of the radio connection state on the basis of whether data related to the terminal is generated during a transfer duration. Here, the first sub-state is a state in which resources for terminal context information related to the data communication are allocated in a first layer and a second layer, and the second sub-state is a state in which the resource is allocated in the first layer and is released in the second layer.
