1. A method of performing a small data transmission (SDT) procedure by a user equipment (UE) in a wireless communication system, the method comprising:
receiving a radio resource control (RRC) release message including SDT configuration information;
converting a current state to an RRC INACTIVE state based on the RRC release message; and
performing the SDT procedure based on the SDT configuration information,
wherein the SDT configuration information includes a configured grant (CG) configuration for the SDT procedure an uplink bandwidth part (BWP) configuration for the SDT procedure, and a downlink BWP for the SDT procedure,
wherein the SDT configuration is configured for a specific cell, and
wherein the UE stops a TAT (Time Alignment Timer) running for the SDT procedure based on an initiation of the SDT procedure for a cell different from the specific cell.
