Abstract: Mechanism on configured grant transmissions is provided. According to embodiments of the present disclosure, after transmitting a configured grant transmission to the network device, the terminal device receives a response to the configured grant transmission. In some embodiments, if the response comprises a timing advance command, the timer for validity of the configured grant transmission is stopped. Alternatively, if the response does not comprise a timing advance command, the timer for validity of the configured grant transmission is stopped and the resources for the configured grant transmission are released. In this way, the terminal device only needs to maintain one timer during the configured grant transmission procedure.

The time period at least partially overlaps with a time window associated with the RA procedure and an end of the time period is after an end of the time window. The first apparatus determines whether the RA procedure is successfully completed or contention resolution for the RA procedure is successful. Based on the determination, the first apparatus ignores or performs the command after the end of the time window.

In an example method, the terminal device receives determines at least two TAGs for a serving cell, wherein the at least two TAGs comprise a primary TAG and a secondary TAG. The terminal device determines whether at least one TAT of the at least two TAGs has expired and maintain, based on determining that the at least one TAT has expired, one of the primary TAG and the secondary TAG.

Since the network is aware of the TAT expiry, it knows behaviour of the terminal device and can act accordingly.
