    Abstract: A method and apparatus for random access in repetition mode is provided. Method for random access in repetition mode includes receiving first RACH configuration, second RACH configuration and PDCCH configuration, selecting an uplink on which to perform a random access procedure based on the first rsrp threshold in the first RACH configuration, transmitting a preamble in the next available PRACH occasion based on PRACH configuration index, monitoring PDCCH in search space indicated by random access search space during while random access window is running, receiving a random access response message including a preamble identifier related to the preamble transmission and transmitting Msg3 based on the time domain resource allocation field in the uplink grant in the random access response.

    Abstract: A method and apparatus for operation in NTN is provided. Method for operation in NTN includes receiving SIB1 including the first common offset2 and the first common offset3 and the first reference position in the first NR cell, receiving a first RRC message including a first bitmap and a first DRX configuration in the first NR cell, monitoring PDCCH of the first cell based on the first IE group 1 received in SIB1 and the first IE group 2 received in the first RRC message and the first value determined by the terminal and the first DRX configuration, receiving a second RRC message including a second common offset2 and a second common offset3 and a second reference position and a second DRX configuration and a second bitmap in the first NR cell and monitoring the PDCCH of the second cell based on the second IE group 1 and the second IE group 2 received in the second RRC message and the second value determined by the UE and the second DRX configuration.

    Abstract: A Method and Apparatus for measurement and conditional reconfiguration in non-terrestrial network is provided. The method includes receiving a measurement configuration IE and a conditional reconfiguration IE, performing conditional reconfiguration evaluation based on the measurement configuration IE and a conditional reconfiguration IE, considering the first cell as a triggered cell and applying the stored condRRCReconfig IE of the first cell. In the evaluation, at least two comparisons are performed based on a distance hysteresis and distance between the terminal and one or more reference positions.

    Abstract: A method and apparatus for performing connection resumption is provided. The m ethod includes transmitting UECapabilityInformation to the base station, The UECapability Information includes type 1 SDT support information and type 2 SDT support information, transmitting a message containing the UE NETWORK CAPACITY to the AMF, Specific b its in the UE NETWORK CAPABILITY indicate whether RRC CONNECTION RESUME is supported, receiving an RRCRelease from the base station, The RRCRelease comprise s 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 u pon receiving a first paging message or a second paging message.

    Abstract: A method and apparatus for data transfer in RRC_INACTIVE state is provided. Method for data transfer in RRC_INACTIVE state includes transmitting a UECapabilityInformation, receiving a RRCRelease, starting a timer with the timer value set to the timerValue1, receiving a system information and initiating a second resume procedure and stopping the timer after restoring a configuration for SRB1 stored in UE Inactive AS (Access Stratum) context. The RRCRelease includes a first information for second resume procedure and a timerValue1, the first information for second resume procedure includes a SRB2(Signaling Radio Bearer2) indicator and a DRB(Data Radio Bearer) list. The system information includes a first threshold and a second threshold, the first threshold is related to a reference signal received power and the second threshold is related to a data volume.
