Configuration of secondary control channel group
A wireless device receives configuration parameters of a secondary physical uplink control channel (PUCCH) group. The secondary PUCCH group comprises: a PUCCH secondary cell; and a secondary cell. The wireless device receives, during a first time interval, a command activating the secondary cell. The wireless device starts transmission of channel state information for the secondary cell from a second time interval that is a positive number plus a pre-determined number of time intervals after the first time interval. In response to activation of the PUCCH secondary cell being completed in or after the pre-determined number of time intervals after the first time interval, the positive number is based on when activation of the PUCCH secondary cell is completed.

6. The wireless device of claim 3 , wherein the channel state information for the second secondary cell comprises an out of range channel quality index (CQI) in response to valid channel state information with a CQI different from zero being unavailable.
7. The wireless device of claim 1 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to employ a next available uplink resource for reporting the channel state information after the second time interval if there are no uplink resources for reporting the channel state information in the second time interval.
8. The wireless device of claim 1 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to start transmission of channel state information of an activated cell in a secondary PUCCH group from the second time interval.
9. The wireless device of claim 1 , wherein the channel state information comprises an out of range channel quality index (CQI) in response to valid channel state information with a CQI different from zero being unavailable.
10. The wireless device of claim 1 , wherein the command comprises a medium-access-control control element with a bitmap.
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:
receive configuration parameters of cells grouped in:
a secondary physical uplink control channel (PUCCH) group comprising:
a PUCCH secondary cell with a secondary PUCCH; and
a first secondary cell; and
a primary PUCCH group comprising:
a primary cell with a primary PUCCH; and
a second secondary cell;
receive, during a first time interval, a command indicating activation of the first secondary cell and the second secondary cell;
start transmission of channel state information of the second secondary cell from a second time interval that is pre-determined number of time intervals after the first time interval; and
start transmission of channel state information of the first secondary cell from a third time interval that is a positive number plus the pre-determined number of time intervals after the first time interval, wherein, in response to activation of the PUCCH secondary cell being completed in or after the pre-determined number of time intervals after the first time interval, the positive number is based on when the activation of the PUCCH secondary cell is completed.
12. The wireless device of claim 11 , wherein the activation of the PUCCH secondary cell is completed in or after the pre-determined number of time intervals after the first time interval.
13. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to:
start a first deactivation timer associated with the first secondary cell in the second time interval; and
start a second deactivation timer associated with the second secondary cell in the second time interval.
