A wireless device receives from a base station, message(s) comprising configuration parameters of a cell. The configuration parameters may comprise BWP parameters of a first BWP and a second BWP, and a timer value associated with a BWP inactivity timer. A first DCI may be received at a first slot. The first DCI may indicate switching to the second BWP as an active BWP. In response to the first DCI, the first BWP may switch to the second BWP as the active BWP. In response to the first DCI, the BWP inactivity timer may be started at a second slot based on the timer value. The second slot may occur after the first slot by an amount of time determined based on a time offset value. A default BWP may be switched to in response to an expiry of the BWP inactivity timer. |
