Abstract: A method and system for configuring a User Equipment (UE) for dual connectivity mode of operation when the UE is carrier aggregated with one or more serving frequencies served by a Master eNB (MeNB) and one or more serving frequencies served by the Secondary eNB (SeNB). The method allows the UE to autonomously initiate the random access procedure on a SCell of the SeNB after adding or replacing SCell of the SeNB. Further, the method allows the UE to handle a Radio Link Failure (RLF) on one or more data radio bearers established between the UE and the SCell of the SeNB.

Abstract translation: 一种方法和系统，用于当所述UE以由主eNB（MeNB）服务的一个或多个服务频率和由所述辅助eNB服务的一个或多个服务频率进行载波聚合时，配置用于双重连接性操作模式的用户设备（UE） SeNB）。 该方法允许UE在添加或替换SeNB的SCell之后在SeNB的SCell上自主地发起随机接入过程。 此外，该方法允许UE处理在UE与SeNB的SCell之间建立的一个或多个数据无线电承载上的无线电链路故障（RLF）。

Abstract: An example method for managing a UAV control operation includes periodically receiving a request for transmission of UAV assistance information from a network entity and establishing a radio resource control (RRC) connection with the network entity. In response to the received request, the method further includes determining a triggering of at least one event corresponding to an initiation of a UAV control operation and transmitting UAV assistance information to the network entity in an RRC connected state based on the determined triggering of the at least one event. The method further includes receiving a control message from the network entity in response to the transmitted UAV assistance information. The control message includes information related to an execution of the UAV control operation. Thereafter, the method further includes executing the UAV control operation based on the information included in the received control message.

Abstract: The disclosure relates to a fifth generation (5G) communication system or a sixth generation (6G) communication system for supporting higher data rates beyond a fourth generation (4G) communication system such as long term evolution (LTE). A method performed by a core network entity 107 for selecting a selective security mode for applying selective security is provided. The method receives first information block from RAN 106. The first information block includes UE capability to support selective security and preferred selective security mode. Further, core network entity may determine if RAN and core network entity are capable of supporting the preferred selective security mode. Finally, the core network entity applies the preferred selective security on the one or more incoming data packets based on the encryption status of the incoming data packets, when at least one of RAN and core network entity supports the preferred selective security mode.
