INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A wireless device receives RRC message(s) with configuration parameters comprising a deactivation timer value for a deactivation timer of a cell. The deactivation timer starts in response to receiving a MAC CE that indicates activation of the cell. A first DCI comprising a first field indicating an uplink resource block assignment, and a first trigger field indicating that the first DCI is triggered in response to a second trigger. The deactivation timer restarts in response to receiving the first DCI. The second DCI comprises: a second trigger field indicating the second trigger, and a second field indicating a subframe offset value. The deactivation timer restarts in response to receiving the second DCI via a common search space. Transport blocks are transmitted, in response to the second trigger, employing the uplink resource block assignment of a subframe having a position determined based on the subframe offset value. ## Claims ### Claim 1 A method comprising;
