Abstract

A method for performing a configured grant based small data transmission (CG-SDT) in a Radio Resource Control (RRC) INACTIVE state by a user equipment (UE) in a wireless communication system is disclosed. The method comprises steps of performing an initial transmission for the CG-SDT on a configured grant (CG), wherein a configured grant timer (CGT) and a CG-SDT-retransmission timer (CG-SDT-RT) are started by performing the initial transmission; and based on a physical downlink control channel (PDCCH) related to the initial transmission not being received until the CG-SDT-RT expiring during the CGT is running, performing a retransmission of the initial transmission, wherein the CG-SDT-RT is re-started upon performing the retransmission of the initial transmission, wherein, based on the PDCCH related to the initial transmission not being received until the CGT expiring, a SDT failure handling procedure is triggered.
