1. A method performed by a terminal in a wireless communication system, the method comprising:
identifying whether a configured grant-based small data transmission (CG-SDT) timing alignment timer (TAT) expires while a CG-SDT procedure is ongoing;
in case that the CG-SDT TAT expires, identifying whether a physical data control channel (PDCCH) addressed to cell-radio network temporary identity (RNTI) has been received after an initial transmission for the CG-SDT procedure; and
in case that the PDCCH addressed to the C-RNTI has not been received after the initial transmission for the CG-SDT procedure, determining that the ongoing CG-SDT procedure is terminated.
