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.
