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.
