    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: A method of supporting a Handover (HO) by a master evolved Node B (eNB) in a wireless communication system supporting dual connectivity of a User Equipment (UE) for the master eNB and a slave eNB is provided. The method includes when an HO of the UE to the slave eNB is determined, transmitting an HO request message to a target slave eNB, when a HO Ack message is received from the target slave eNB, transmitting an HO trigger request message including identification information of the target slave eNB to a source slave eNB, and when a resource release message is received from the target slave eNB, transmitting an HO success indicator to the source slave eNB.

    Abstract translation: 提供了一种在支持主eNB和从eNB的用户设备（UE）的双连接性的无线通信系统中由主演进节点B（eNB）支持切换（HO）的方法。 该方法包括：当从目标从eNB接收到HO Ack消息时，当从UE确定HO的HO时，向目标从eNB发送HO请求消息，发送包含以下内容的标识信息的HO触发请求消息： 目标从属eNB到源从动eNB，并且当从目标从eNB接收资源释放消息时，向源从eNB发送HO成功指示符。

    Abstract: The disclosure relates to a communication technique for convergence of an IoT technology and a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The disclosure can be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart cart 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. The disclosure defines a mobility method for a terminal residing in a system in which transmission/reception points (TPRs), supporting solely some protocols among entire access stratum protocols comprising PHY, MAC, RLC, PDCP, and RRC, coexist in a wireless communication system. Specifically, the disclosure defines a method for dynamically changing, depending on determination by a base station, a beam and a transmission/reception point to be used for transmitting information to or receiving information from a terminal through a method in which a system using multiple beams notifies, in advance, of a measurement reference signal transmitted using transmission/reception points of different networks, to allow a terminal to select a required reception beam from a corresponding resource and measure beam information of each transmission/reception point, or a terminal transmits measured information as feedback in which each transmission/reception point is specified. Accordingly, the disclosure can provide a criterion of rapid and highly precise determination for changing a beam and a transmission/reception point and thus prevent a terminal from needlessly measuring and reporting, so as to achieve an effect of reduction in the power consumption of the terminal and reduction of delay in change of a transmission/reception point.

    Abstract: The disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a data transmission rate higher than 4th generation (4G) communication systems such as long term evolution (LTE). A method performed by a near-real time (RT) radio access network (RAN) intelligent controller (RIC) is provided. The method includes a step of receiving a RIC indication message from an E2 node, wherein the RIC indication message includes user equipment (UE)-related information, the UE-related information includes information for indicating the radio resource control (RRC) state, and the RRC state can be one from among a plurality of states including RRC connected, RRC inactive and RRC idle states.
