Abstract:
A wireless device may receive one or more messages comprising configuration parameters for a primary cell and a secondary cell. The configuration parameters may indicate a deactivation timer for the secondary cell and a bandwidth part (BWP) inactivity timer for the primary cell. The wireless device may start the deactivation timer in response to activating the secondary cell. The wireless device may start the BWP inactivity timer in response to switching an active BWP of the primary cell. The wireless device may stop the BWP inactivity timer of the primary cell based on initiating a random-access procedure for the secondary cell. In response to the deactivation timer of the secondary cell expiring during the random-access procedure, the wireless device may restart the BWP inactivity timer of the primary cell.
