    Abstract: A method of a first base station in a communication system and an apparatus therefor are provided. The method includes determining an addition mode configured to add a second base station, identifying whether to add the second base station based on the addition mode, and performing a procedure of adding the second base station based on the second base station being identified as being added. The addition mode may indicate one of a combination of at least one of a blind addition, a traffic criterion addition and a measurement report criterion addition. The method may be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail business, security and safety-related service) based on the 5th generation (5G) communication technology and Internet of Things (IoT)-related technology. The method and apparatus propose a connection management method in a dual connectivity system.

    Abstract: The present disclosure relates to a communication scheme and system for converging a 5th generation (5G) communication system for supporting a data rate higher than that of a 4th generation (4G) system with an internet of things (IoT) technology. The present disclosure is applicable to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, and security and safety-related services) based on the 5G communication technology and the IoT-related technology. A proposed method for a base station to transmit information controlling configuration of an uplink (UL) secondary component carrier (SCC) corresponding to a secondary cell in a wireless communication system supporting carrier aggregation (CA) includes identifying first information associated with an uplink electric field of a primary cell, transmitting measurement configuration information associated with the secondary cell to a terminal, receiving a measurement report message associated with the secondary cell from the terminal, identifying second information associated with a downlink electric field of the secondary cell based on the measurement report message, and transmitting the information controlling configuration of the UL SCC of the secondary cell to the terminal based on at least one of the first information or the second information.

    Abstract: According to an embodiment of the present invention, provided are a method for providing a broadcast service of an MBMS coordination entity (MCE) in a mobile communication system, and an MCE for performing the same. The method comprises the steps of: transmitting a terminal counting request message to at least one base station in a multicast-broadcast single frequency network (MBSFN) area; receiving a counting result message comprising the number of terminals receiving a multimedia broadcast multicast service (MBMS) session for each cell of the base station from the base station; and determining MBMS resource allocation for each cell in the MBSFN area on the basis of the counting result message. In addition, it is possible to provide a base station and a terminal operating together with the MCE, and a method for the operation thereof.
