Control of BWP inactivity timer for primary cell based on deactivation timer of secondary cell

A base station comprising:

• one or more processors;
• memory storing instructions that, when executed by the one or more processors, cause the base station to:
• transmit, to a wireless device, one or more messages comprising configuration parameters for a primary cell and a secondary cell, wherein the configuration parameters indicate:
• a deactivation timer for the secondary cell;
• and
• a bandwidth part (BWP) inactivity timer for the primary cell;
• start the deactivation timer in response to activating the secondary cell;
• start the BWP inactivity timer in response to switching an active BWP of the primary cell;
• stop the BWP inactivity timer of the primary cell based on triggering a random-access procedure for the secondary cell;
• and
• in response to the deactivation timer of the secondary cell expiring during the random-access procedure, restart the BWP inactivity timer of the primary cell.

A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:

• receive one or more messages comprising configuration parameters for a primary cell and a secondary cell, wherein the configuration parameters indicate:
• a deactivation timer for the secondary cell;
• and
• a bandwidth part (BWP) inactivity timer for the primary cell;
• start the deactivation timer in response to activating the secondary cell;
• start the BWP inactivity timer in response to switching an active BWP of the primary cell;
• stop the BWP inactivity timer of the primary cell based on triggering a random-access procedure for the secondary cell;
• and
• in response to the deactivation timer of the secondary cell expiring during the random-access procedure, restart the BWP inactivity timer of the primary cell.
