Abstract
A method and a user equipment (UE) for small data transmission (SDT) are provided. The method includes: receiving, from a base station (BS), a common time alignment (TA) timer configured via system information; receiving, from the BS, a configured grant (CG)-SDT-specific TA timer configured via a CG-SDT-specific configuration; and determining whether to maintain or release a physical uplink control channel (PUCCH) based on the expirations of the common TA timer and the CG-SDT-specific TA timer, wherein the PUCCH is maintained if the UE determines that the CG-SDT-specific TA timer has expired, and the PUCCH is released if the UE determines that the common TA timer has expired.
