Abstract: The present invention relates to a method of receiving data units by a user equipment (UE) in a wireless communication system. In particular, the method includes the steps of: receiving the data unit during an active time of a first discontinuous reception (DRX) configuration related to a multicast transmission for a Hybrid Automatic Repeat and request (HARQ) process; transmitting a negative response to the network based on the data unit being not successfully decoded; starting a HARQ Round-trip Time (RTT) timer of a second DRX configuration related to a unicast transmission for the HARQ process; and monitoring a physical downlink control channel (PDCCH) related to a retransmitted data unit during an active time of the second DRX configuration, based on the HARQ RTT timer expiring.

Abstract: The present invention relates to a method for transmitting a medium access control (MAC) protocol data unit (PDU) by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of generating the MAC PDU; and based on a listen before talk (LBT) succeeding, transmitting the MAC PDU on an uplink resource using a Hybrid automatic repeat request (HARQ) process; wherein, based on the MAC PDU including user data, a configured grant timer (CGT) and a configured grant retransmission timer (CGRT) for the HARQ process are started, and a status of the HARQ process is set to not pending, wherein, based on the MAC PDU not including the user data and being multiplexed with uplink control information (UCI), the CGT and the CGRT for the HARQ process are not started, and the status of the HARQ process is set to not pending.

Abstract: The present disclosure relates to a method of performing data transmissions in a Radio Resource Control (RRC) INACTIVE state by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of generating at least one Small Data Transmission (SDT) data unit that can be transmitted in RRC INACTIVE state; triggering a SDT procedure for transmitting the at least one SDT data unit in RRC INACTIVE state; generating a non-SDT data unit that cannot be transmitted in RRC_INACTIVE during the SDT procedure; generating an indication message informing that there is the non-SDT data unit, based on an uplink grant related to the SDT procedure for transmitting the indication message being available; and transmitting the indication message via a Dedicated Control Channel (DCCH) during the SDT procedure to a network.

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 receiving data units by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of receiving a first data unit based on a Group-Radio network temporary identifier (G-RNTI) from a network; decoding the first data unit and identifying a logical channel related to the first data unit based on the G-RNTI; based on decoding the first data unit failing, transmitting a negative response related to the first data unit to the network; receiving a second data unit based on a Cell-RNTI (C-RNTI) from a network; decoding the second data unit; and based on the second data unit being a retransmitted data unit of the first data unit, identifying the logical channel based on the G-RNTI.

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 a Listen Before Talk (LBT) procedure by a user equipment (UE) in a wireless communication system. Especially, the method includes the steps of detecting a LBT failure based on a first LBT failure parameter set; receiving a second LBT failure parameter set before transmitting a LBT failure report; and if the second LBT failure parameter set requires more frequent LBT failure report than the first LBT failure parameter set, transmitting the LBT failure report related to the LBT failure.
