    Abstract: Aspects of the present disclosure are to address the problems of performing time-based reconfiguration in mobile network. The method of the terminal includes receiving a first system information, receiving a second system information, receiving a RRC reconfiguration message, triggering a TAR before the first time point based on the first NTN configuration in the second scheduling information, and triggering the TAR after the first time point based on the second NTN configuration in the second scheduling information. The TAR comprises a timing advance field indicating a timing advance value applied by the terminal. The second system information comprises the first NTN configuration and the second NTN configuration.

    Abstract: Aspects of the present disclosure are to address the problems of performing time-based reconfiguration in mobile network. The method of the terminal includes receiving a first system information, receiving a second system information, determining a total amount of timing advance (TTA) based on the first NTN configuration or based on second NTN configuration and performing uplink transmission based on the TTA. The TTA is determined based on, before the stop time, the first NTN configuration and the constant offset. The TTA is determined based on, after the stop time, the second NTN configuration and the constant offset.

    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 to enhance uplink coverage is provided. Method for enhancing uplink coverage includes receiving a SIB1 and performing a random access procedure with preamble repetition in case that Reference Signal Received Power (RSRP) of downlink pathloss reference is less than at least one of one or more thresholds related to preamble repetition. The SIB1 comprises a set of parameters related to system information scheduling and a set of parameters related to uplink configuration. Random access resource indicated in the set of parameters related to system information scheduling is used in case that the random access procedure is triggered for System Information (SI) request. Random access resource indicated in the set of parameters related to uplink configuration is used in case that the random access procedure is triggered for data transmission.

    Abstract: A Method and Apparatus to address problem of RACH resource partitioning. The method includes receiving SIB1 from the base station, determining an uplink for a random access procedure based on rsrpThresholdSSB-SUL, determining a first target feature combination, determining that the CE is applicable based on rsrp-ThresholdSSB-CE, determining a second target feature combination by adding CE in the first target feature combination, selecting a second RACH-ConfigCommon based on the comparison between the target feature combination and the one or more feature combinations associated with the one or more second RACH-ConfigCommons of the selected uplink and performing a random access procedure based on the selected second RACH-ConfigCommon.
