    Abstract: The present invention relates to a method of transmitting a Time Alignment Timer (TAT) status report by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of configuring one or more Timing Advance Groups (TAGs); receiving a Timing Advance Command (TAC) for one of the one or more TAGs; starting a TAT for the one TAG; triggering the TAT status report when a remaining time of the TAT for the one TAG is less than a threshold for the one TAG; and transmitting the TAT status report to a network, wherein the TAT status report includes a first type indication indicating that the remaining time of the TAT for the one TAG is less than the threshold.

    Abstract: The present invention relates to a method of performing a Random Access (RA) procedure in a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of configuring at least one first bandwidth part (BWP) on which the RA procedure is performed for transmitting data in a Radio Resource Control (RRC) INACTIVE state; configuring a second BWP on which the RA procedure is performed for shifting to a RRC CONNECTED state from the RRC INACTIVE state; performing the RA procedure on the at least one first BWP when the UE determines to transmit the data in the RRC INACTIVE state; and performing the RA procedure on the second BWP when the UE determines to shift to the RRC CONNECTED state from the RRC INACTIVE state.

    Abstract: The present invention relates to a method of transmitting a data unit using a Random Access (RA) procedure by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of configuring a first RA preamble group and a second RA preamble group, wherein RA preambles belonging to the first RA preamble group indicates that a RA Response (RAR) is not required and RA preambles belonging to the second RA preamble group indicates that the RAR is required; selecting one of the first preamble group and the second RA preamble group based on whether a response of the transmitted data unit from a network is required or not; and transmitting one of the RA preambles belonging to the selected RA preamble group with the data unit to the network.

    Abstract: The present invention constructs L RLC PDUs, where L is larger than 1; and submit the L RLC PDUs to a medium access control (MAC) layer for a transmission opportunity. The L RLC PDUs include a first RLC PDU having a poll to trigger status reporting at a receiving device and a second RLC PDU not having the poll and having a highest sequence number (SN) among SNs of the L RLC PDUs. The present invention sets a state variable to a highest SN among SNs of RLC PDUs having the poll submitted to the MAC layer, upon submitting the first RLC PDU to the MAC layer.
