    Abstract: A method and apparatus for measurement in non-terrestrial network is provided. The method includes receiving a measurement object configuration comprising a first SMTC and a third SMTC list, setting up a first SS/PBCH block timing configuration for said measurement object based on the first SMTC, setting up additional SS/PBCH block timing configurations based on the first SMTC and the third SMTC list for the cells indicated in said pci-List parameter and deriving a measurement result based on the SS/PBCH block.

    Abstract: A method and apparatus for performing connection resumption is provided. The method includes transmitting UECapabilityInformation to the base station, The UECapabilityInformation includes type 1 SDT support information and type 2 SDT support information, transmitting a message containing the UE NETWORK CAPACITY to the AMF, Specific bits in the UE NETWORK CAPABILITY indicate whether RRC CONNECTION RESUME3 is supported, receiving an RRCRelease from the base station, The RRCRelease comprises a SuspendConfig, In response to receiving said RRCRelease message, entering the RRC_INACTIVE state and performs cell selection, monitoring the paging channel in the selected cell, and initiating RRC CONNECTION RESUME3 or RRC CONNECTION RESUME1 upon receiving a first paging message or a second paging message.

    Abstract: A Method and Apparatus for multi-SIM operation during handover is provided. The method includes receiving from a base station a first RRCReconfiguration, transmitting to the base station a UEAssistanceInformation, starting the first timer after initiating transmission of UEAssistanceInformation, receiving from the base station a second RRCReconfiguration and starting the second timer before initiating random access procedure. The first RRCReconfiguration includes a configuration information related to terminal state transition, the configuration information related to terminal state transition includes a information for a first timer, the first timer is a timer related to terminal state transition. The UEAssistanceInformation includes a information related to terminal's state. The second RRCReconfiguration includes a ReconfigurationWithSync, the ReconfigurationWithSync includes a information for a second timer related to handover. The first timers stops if the second timer expires while the first timer is running. The second timers stops if the first timer expires while the second timer is running.

    Abstract: A method and apparatus for layer 2 mobility is provided. Method for lower layer mobility includes receiving a RRCReconfigruation from the base station, receiving a TAC MAC CE in a first cell and determining Timing advance between downlink and uplink (TTA). If the type1 TAC MAC CE is received, the terminal determining Timing advance between downlink and uplink (TTA) of a second TAG of a first mobility group based on the first field (TAC) and the second field (TAG ID) and a first subcarrier spacing. If the type2 TAC MAC CE is received, the terminal determining Timing advance between downlink and uplink (TTA) of a second TAG of a second mobility group based on the first field (TAC) and the second field (TAG ID) and a third field (CMG ID field) and a second subcarrier spacing.

    Abstract: A Method and Apparatus for application layer measurement reporting based on segmentation is provided. The method includes receiving a first SRB-ToAddMod IE, establishing a SRB1 based on the first SRB-ToAddMod IE, receiving a second SRB-ToAddMod IE, establishing a SRB4 based on the second SRB-ToAddMod IE, receiving a first RRC message, generating a second RRC message based on the first RRC message, generating a one or more ULDedicatedMessageSegment by segmenting the second RRC message in case that the second RRC message is larger than a specific size and the first RRC message includes a rrc-SegAllowed, transmitting, the one or more ULDedicatedMessageSegment. The one or more ULDedicatedMessageSegment are transmitted via SRB4 in case that the first RRC message is a RRCReconfiguration received via SRB1 and the first RRC message includes a first configuration information.
