A method and an apparatus for controlling a packet transmission for a split bearer to reduce latency in a wireless communication system are provided. A method by a third node for controlling a packet transmission for a split bearer connected to a first node and a second node in a wireless communication system includes obtaining information related to a buffer state of each of the first node and the second node, determining a packet arrival time at a terminal through each of the first node and the second node based on the information related to the buffer state of each of the nodes, selecting one of the first node and the second node based on a comparison of the packet arrival time corresponding to the first node with the packet arrival time corresponding to the second node, and transmitting a packet to the terminal through the selected node.

Method and apparatus for controlling packet transmission for reducing latency in wireless communication system

A communication method and system for converging a 5-Generation (5G) communication system for supporting higher data rates beyond a 4-Generation (4G) system with a technology for Internet of Things (IoT) is provided. The disclosure may be applied to 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. The disclosure proposes a transmission path determination method and apparatus for latency reduction.

Method and apparatus for determining transmission path of packet in wireless communication

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.

Device and method for data transmission between base stations in wireless communication system

A method for managing a buffer by a base station in a wireless communication system is provided. The method includes calculating a transmission delay time that is an average of waiting time of packets transmitted for a predetermined time, identifying whether the calculated transmission delay time is greater than a preset delay time threshold value, and rearranging, if the transmission delay time is greater than the delay time threshold value, a transmission order of the packets in the buffer.
