    Abstract: The present disclosure relates to mobility management in wireless communications. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: receiving mobility commands of candidate cells, mobility conditions for the candidate cells, and information for a timer; determining a first target cell among the candidate cells which satisfies a mobility condition for the first target cell; after determining the first target cell, determining a second target cell among the candidate cells which satisfies a mobility condition for the second target cell while the timer is running, wherein a priority of the second target cell is higher than a priority of the first target cell; and performing a mobility to the second target cell based on a mobility command of the second target cell.

    Abstract: The present disclosure relates to link management (LM) in wireless communications. According to an embodiment of the present disclosure, a method performed by a user equipment (UE) configured to operate in a wireless communication system comprises: receiving, from a network, a configuration for multiple candidate cells which are candidates for a serving cell; selecting at least one candidate cell among the multiple candidate cells; and performing a link management (LM) operation on the at least one candidate cell.

    Abstract: A method and apparatus for support of load balancing for supplementary uplink (SUL) in central unit (CU)-distributed unit (DU) architecture in a new radio access technology (NR) is provided. A gNB central unit (gNB-CU) receives, from at least one gNB distributed unit (gNB-DU), information related to a load status of supplementary uplink (SUL) for the at least one gNB-DU, and determines to adjust at least one parameter related to the SUL for a gNB-DU, among the at least one gNB-DU, based on the information related to the load status of the SUL for the gNB-DU. Upon receiving information related to the at least one parameter related to the SUL from the gNB-CU, the gNB-DU may adjust the at least one parameter related to the SUL based on the information related to the at least one parameter related to the SUL.

    Abstract: Provided are a method for a user equipment (UE) to perform early data transmission (EDT) in a wireless communication, and an apparatus supporting the same. The method may include: transmitting a first radio resource control (RRC) message for the EDT, to a base station; receiving a second RRC message in response to the first RRC message, from the base station; if the second RRC message indicates that the EDT is successful, considering that the EDT ends successfully; if the second RRC message indicates that the EDT is unsuccessful, considering that the EDT ends unsuccessfully; and entering a RRC_IDLE state.

    Abstract: A method and apparatus for transmitting a user equipment (UE) assistance information message in a wireless communication system is provided. Upon receiving N consecutive number of indications of early-out-of-synchronization/early-in-synchronization from a lower layer of the UE, the UE transmits the UE assistance information message including the early-out-of-synchronization/early-in-synchronization indication to the network, and starts a prohibit timer for prohibiting transmission of the UE assistance information message including the early-out-of-synchronization/early-in-synchronization indication to the network. Further, the UE cancels a prohibit timer, if running, for prohibiting transmission of a UE assistance information message including an early-in-synchronization/early-out-of-synchronization indication.

    Abstract: Provided are a method for a user equipment (UE) to perform early data transmission (EDT) in a wireless communication, and an apparatus supporting the same. The method may include: receiving system information including a threshold for the EDT; determining whether or not a condition for initiating the EDT is satisfied, by comparing the threshold for the EDT with a size of data for transmission; if the condition is satisfied, performing the EDT; and if the condition is not satisfied, performing a radio resource control (RRC) connection establishment or resume procedure.
