1. A first device, comprising:
at least one processor; and
at least one memory including computer program code;
wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the first device to:
perform an initial transmission of Configured Grant Small Data Transmission (CG-SDT) using a second configured uplink grant to a second device;
determine a confirmation is not received from the second device before a configured timer for CG-SDT retransmission expires;
select a first configured uplink grant for retransmission of the initial transmission of CG-SDT, a first transport block size (TBS) associated with the first configured uplink grant being equal to a second TBS associated with the second configured uplink grant for the initial transmission of CG-SDT, and at least one first Hybrid Automatic Repeat Request (HARQ) process associated with the first configured uplink grant being the same as at least one second HARQ process associated with the second configured uplink grant; and
perform the retransmission to the second device based on the first configured uplink grant.
