1. A method comprising:
transmitting, by a base station to a wireless device, configuration parameters of a cell, the configuration parameters comprising:
bandwidth part (BWP) parameters of a first BWP and a default BWP;
a first timer value associated with a cell deactivation timer; and
a second timer value associated with a BWP inactivity timer;
transmitting a downlink control information (DCI) indicating an activation of the cell for the wireless device;
in response to transmitting the DCI:
activating the cell for the wireless device; and
starting the cell deactivation timer based on the first timer value;
activating, in response to activating the cell, the first BWP of the cell for the wireless device;
starting the BWP inactivity timer based on the second timer value;
transmitting, by the base station to the wireless device, a second DCI;
in response to transmitting the second DCI:
restarting the BWP inactivity timer; and
restarting the cell deactivation timer; and
in response to expiry of the BWP inactivity timer, switching from the first BWP to the default BWP as an active BWP.
