Abstract: A wireless device receives, from a base station, one or more radio resource control messages indicating: a first value of a first bandwidth part (BWP) inactivity timer for a first cell, and a second value of a second BWP inactivity timer for a second cell. A downlink control information (DCI) is received, via the first cell, indicating a set of sidelink resources for sidelink transmission via the second cell. In response to the DCI, the first BWP inactivity timer is restarted based on the first value. A transport block, of the sidelink transmission, is transmitted via a sidelink resource of the set of sidelink resources. In response to transmitting via the sidelink resource, the second BWP inactivity timer is restarted based on the second value.
