Abstract: The present invention relates to a method of performing a user plane integrity protection (UPIP) based on data volume by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of activating an integrity protection for a radio bearer (RB): receiving a Packet Data Convergence Protocol (PDCP) data unit related to the RB from an upper layer; and transmitting the PDCP data unit via the RB to a reception end, with applying the integrity protection to the PDCP data unit, wherein, based on a data volume of the PDCP data being greater than a data volume threshold, applying the integrity protection is skipped.

Abstract: The present invention relates to a method of transmitting a Scheduling Request (SR) based on a time Alignment Timer (TAT) by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of receiving information related to a time Alignment Timer (TAT) for a Timing Advance Group (TAG) to which a serving cell belongs; starting the TAT for the TAG; based on a data packet to be transmitted via the serving cell being received from an upper layer, determining a difference time between a time point of a first available SR resource in SR resource configuration for the TAG and an expected expiring time of the TAT; based on the difference time being greater than a threshold, transmitting a SR for the data packet on the first available SR resource to a network, wherein, based on the difference time being less than the threshold, a random access (RA) procedure is triggered.

Abstract: The present invention relates to a method of performing data transmission by a user equipment (UE) in a radio resource control (RRC) INACTIVE state at a wireless communication system. Especially, the method includes the steps of upon a reception of a Packet Data Convergence Protocol (PDCP) service data unit (SDU) from an upper layer, starting a discard timer related to the PDCP SDU; generating a medium access control (MAC) protocol data unit (PDU) including the PDCP SDU; starting a random access (RA) procedure for transmitting the MAC PDU; and based on the discard timer expiring before the RA procedure is completed, stopping the RA procedure.

Abstract: A method and apparatus for master cell group (MCG) radio link failure (RLF) reporting during secondary cell group (SCG) suspension in a wireless communication system is provided. A wireless device detects a failure on a master cell group (MCG) while a secondary cell group (SCG) is suspended, and transmits MCG failure information informing the failure on the MCG by using a physical uplink control channel (PUCCH) format via the SCG, based on unavailability of physical uplink shared channel (PUSCH) transmission via the SCG.

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.
