Deactivation Timer for a Secondary Cell with a Control Channel

Abstract

A wireless device receives configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups. The PUCCH groups comprise a secondary PUCCH group. The secondary PUCCH group comprises a PUCCH secondary cell with a secondary PUCCH. A deactivation timer of the PUCCH secondary cell is restarts in response to a physical downlink control channel (PDCCH) on any secondary cell, other than the PUCCH secondary cell, in the secondary PUCCH group indicating an uplink grant or a downlink assignment. The PUCCH secondary cell is deactivated in response to the deactivation timer expiring.

 restarting a deactivation timer of the PUCCH secondary cell in response to a physical downlink control channel (PDCCH) on any secondary cell, other than the PUCCH secondary cell, in the secondary PUCCH group indicating an uplink grant or a downlink assignment; and 
 deactivating the PUCCH secondary cell in response to the deactivation timer expiring. 
   
     
     
         2 . The wireless device of  claim 1 , wherein the operations further comprise maintaining configuration of PUCCH resources of the PUCCH secondary cell when the PUCCH secondary cell is deactivated.

         8 . The wireless device of  claim 1 , wherein cross carrier scheduling of a cell in a primary PUCCH group is only configurable for another cell in the primary PUCCH group. 
     
     
         9 . The wireless device of  claim 1 , wherein cross carrier scheduling of a cell in the secondary PUCCH group is only configurable for another cell in the secondary PUCCH group. 
     
     
         10 . The wireless device of  claim 1 , wherein the operations further comprise receiving a deactivation timer value for a deactivation timer. 
     
     
         11 . A wireless device comprising:
 one or more processors; and   memory storing instructions that, when executed by the one or more processors, cause the wireless device to perform operations comprising:
 receiving configuration parameters of cells grouped into physical uplink control channel (PUCCH) groups comprising a secondary PUCCH group, the secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH; 
 restarting a deactivation timer of the PUCCH secondary cell in response to a physical downlink control channel on a cell, other than the PUCCH secondary cell, in the secondary PUCCH group indicating an uplink grant or a downlink assignment for any secondary cell, other than the PUCCH secondary cell, in the secondary PUCCH group; and 
 deactivating the PUCCH secondary cell in response to the deactivation timer expiring. 
   
     
     
         12 . The wireless device of  claim 11 , wherein the operations further comprise maintaining configuration of PUCCH resources of the PUCCH secondary cell when the PUCCH secondary cell is deactivated.
