Classification: CPC H | IPC H

Claim 0:
1. A method for transmitting uplink (UL) data by a user equipment (UE) in a wireless communication system, the method comprising:
based on the UE transmitting the UL data on a first UL resource of a configured grant (CG) configuration based on a Hybrid-ARQ (HARQ) process, starting a CG retransmission timer for the HARQ process and a CG timer for the HARQ process,
wherein the CG timer is longer than the CG retransmission timer;
after an expiration time point of the CG timer, performing retransmission of the UL data based on the HARQ process,
wherein, while the CG retransmission timer is running, the retransmission of the UL data based on the HARQ process is prohibited, and
wherein, while the CG timer is running, a new transmission of UL data based on the HARQ process is prohibited,
wherein, based on a second UL resource of the CG configuration being configured between an expiration time point of the CG retransmission timer and an expected expiration time point of the CG timer, the retransmission of the UL data is performed on the second UL resource,
wherein, based on the second UL resource of the CG configuration not being configured between the expiration time point of the CG retransmission timer and the expected expiration time point of the CG timer, stopping the CG timer before the expected expiration time point of the CG timer and the retransmission of the UL data is performed on a third UL resource of the CG configuration configured after the expected expiration time point of the CG timer.
