DEACTIVATION TIMER IN A WIRELESS DEVICE AND WIRELESS NETWORK
A wireless device receives one or more messages comprising configuration parameters for a plurality of cells comprising a secondary cell.

receive, using the radio resource assignment and during a first transmission time interval associated with the periodicity, one or more transport blocks; and
restart, based on the receiving the one or more transport blocks, the deactivation timer for the secondary cell.
14 . The non-transitory computer-readable medium of claim 13 , wherein the instructions, when executed, configure the wireless device to receive a command indicating activation of the secondary cell.
15 . The non-transitory computer-readable medium of claim 14 wherein the command comprises a media access control (MAC) control element (CE).
16 . The non-transitory computer-readable medium of claim 13 , wherein the instructions, when executed, configure the wireless device to determine a plurality of periodic resources, wherein a resource of the plurality of periodic resources is determined based on the periodicity.
