    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.

    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 based on reporting on terminal state is provided. Method for Multi-SIM operation based on reporting on terminal state 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, transmitting to the base station a RRCReconfigurationComplete in response to the second RRCReconfiguration and starting the first timer if the reconfigurationWithSync was included in a masterCellGroup in the second RRCReconfiguration and if the terminal initiated transmission of the UEAssistanceInformation during a specific time period.

    Abstract: A Method and Apparatus for performing small data transmission is provided. The method includes receiving a RRCRelease, determining a one or more radio bearers configured for SDT based on the first information, discarding all stored PDCP SDU and PDCP PDU in PDCP entity of SRB1 and SRB2, receiving a SystemInformationBlock1, monitoring PDCCH or the first type CSS configured by the first search space for DCI with CRC scrambled by the first identifier step, initiating a SDT based on the first information and the second information, monitoring PDCCH for a first type CSS configured by a second search space for DCI with a second identifier during when ra-ResponseWindow, resuming the radio bearers, transmitting a UEAssistanceInformation if data mapped to a one or more radio bearers not configured for SDT becomes available, monitoring PDCCH for a second type CSS configured with a third identifier.
