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). The communication method of a base station in a wireless communication system, according to one embodiment of the disclosure, can comprise the steps of: setting a transmission period of a poll bit for indicating the transmission of information on whether a packet has been successfully received; generating a packet including the poll bit set on the basis of the transmission period; and transmitting the generated packet to a terminal.

Abstract: The present disclosure relates to a research that has been conducted with the support of the “Cross-Depaitmental Giga KOREA Project” funded by the government (the Ministry of Science and ICT) in 2017 (No. GK17N0100, millimeter wave 5G mobile communication system development). The present disclosure relates to a communication technique for convergence of a 5G communication system for supporting a higher data transmission rate beyond a 4G system with an IoT technology, and a system therefor. The present disclosure may be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security and safety-related service, etc.) on the basis of a 5G communication technology and an IoT-related technology.

Abstract: A method and apparatus is provided that controls the handover between distributed units (DUs) (inter-DU handover) in an eNB including a central unit (CU) and a distributed unit (DU). The method and system fuses 5G communication systems with IoT technology to transmission data at a high rate after 4G systems. The communication method and system is applied to intelligent services, based on 5G communication technology and IoT related technology, for example, smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security, safety-related services, etc. The method of performing communication in a communication node of a mobile communication system includes: transmitting, to a source node, a first message instructing handover; receiving, from the source node, a second message including information related to a PDU transmitted to a terminal; receiving, from a target node, a third message related to the reception of a random access preamble of the terminal; and transmitting, to the target node, downlink data, based on the second message, in response to the third message.
