    Abstract: A base station may transmit a system information block 1 (SIB1) message of a cell. The SIB1 message may indicate a plurality of configuration parameters comprising a common uplink configuration of an uplink bandwidth part (BWP). The common uplink configuration of the uplink BWP may comprise: a common random access channel (RACH) configuration; a first threshold for determining whether to select a resource associated with a first message 1 (msg1) repetition number, wherein msg1 corresponds to physical random access channel (PRACH) preamble; a second threshold for determining whether to select a resource associated with a second msg1 repetition number; and a second RACH configuration associated with feature combination. The second RACH configuration may comprise a first feature combination preamble parameter that indicates the first msg1 repetition number. A wireless device may determine, based on the first threshold, the first msg1 repetition number, and repeatedly transmit, based on the determined first msg1 repetition number, a PRACH preamble of a random access procedure associated with the first feature combination preamble parameter.

    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.
