    Abstract: Disclosed are a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system, and a system thereof. The present disclosure can be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety-related services, and the like), based on a 5G communication technology and an IoT-related technology. One embodiment of the present invention relates to a method by which a terminal updates system information, and a terminal for performing the method, which comprises the steps of: acquiring first system information and second system information from a first cell; starting a timer corresponding to the second system information; determining whether the second cell is a cell that shares the second system information with the first cell, if the terminal has moved from the first cell to the second cell; and updating the second system information on the basis of the determination result.

    Abstract: Embodiments herein disclose a method for handling an RLF in a wireless communication system by a UE (100). The method includes receiving a measurement configuration including a second timer (150) from a SN (300). Further, the method includes configuring the UE with the second timer associated with a measurement report for a PSCell of the SN. Further, the method includes starting the second timer when the measurement report is triggered while a first timer (140) for the PSCell is running. Further, the method includes detecting an expiry of one of: the first timer and the second timer for the PSCell. Further, the method includes declaring an SCG RLF upon expiry of one of: the first timer and the second timer whichever expires sooner. Further, the method includes initiating an SCG failure procedure towards an MN (300) upon declaring SCG RLF.

    Abstract: An operating method performed by a user equipment (UE) in a wireless communication system according to some embodiments of the present disclosure may include: generating a source link for transmitting and receiving data to and from a source base station; receiving, from the source base station, a radio resource control (RRC) message including configuration information for handover to a target base station; starting a timer, in response to the reception of the RRC message; transmitting, to the target base station, a message for handover to the target base station while the timer is running; and determining, in a case where the handover to the target base station fails up until the timer expires, whether to trigger RRC re-establishment, based on a state of the source link.
