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). According to embodiments, a method performed by a distributed unit (DU), the method comprises generating a control plane (C-plane) message for multiple ports, the C-plane message including section information and a section extension; and transmitting the C-plane message to a radio unit (RU) via a specific port of the multiple ports. The section information includes information on a beam identifier (ID). The section extension includes beam group type information for indicating a type of beam grouping, and port information for indicating a total number of one or more extended antenna-carrier (eAxC) ports indicated by the section extension.

Abstract: According to an embodiment of the present invention, a method by which a base station receives a measurement report in a wireless communication system using a carrier integration technique comprises the steps of: generating a cell list for a second cell according to whether the second cell to be added from a first cell belongs to the same cell group as the first cell; transmitting, to a terminal, a measurement report command including configuration information related to the cell list; and receiving, from the terminal, a measurement report of the second cell on the basis of the configuration information, if the second cell belongs to the same cell group as the first cell.

Abstract: The present disclosure is a research which has been conducted with the support of the “Cross-Departmental Giga KOREA Project” of the government (the Ministry of Science and ICT) in 2017 (No. GK17N0100, Development for mmWave-based 5G mobile communication system). 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 IoT-related technology. The present disclosure provides a system and a control method therefor, which can prevent, when a dual connectivity scheme is used, delay and data loss due to an operation of releasing and adding a secondary node cell or a process of resetting a user plane and updating a security key and a procedure of forwarding data between user planes through a common anchored user plane and changing (updating) a path between the user plane and a core.
