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.

A first apparatus receives, from a second apparatus, a command indicating the first apparatus to skip monitoring a downlink control channel between the second apparatus and the first apparatus for a time period. The first apparatus initiates an RA procedure towards the second apparatus. 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.

Abstract: A network node in a wireless network sends a selected BWP toward a UE, the selected BWP to be used by the UE during a connection procedure used to connect the UE to the wireless network after the UE enters an idle or inactive state. The selected BWP is different from an initial BWP that would have been used by the UE during the connection procedure. The network node receives from the user equipment a message for connection to the wireless network using the selected BWP. The UE receives the selected BWP and uses the selected BWP to send, while in one of an idle state or an inactive state, a message for connection to the wireless network using the selected BWP (e.g., and not the initial BWP).
