a primary PUCCH group comprising the primary cell with the primary PUCCH transmitted to the base station; and

a secondary PUCCH group comprising the secondary cell with the secondary PUCCH transmitted to the base station.

5. The wireless device of claim 4 , wherein:

the primary TPC index indicates a first DCI format;

the secondary TPC index indicates the first DCI format;

the secondary TPC index has a TPC index value different from that of the primary TPC index; and

the DCI is of the first DCI format.

6. The wireless device of claim 5 , wherein:

the array of TPC commands comprises the TPC command and a first TPC command; and

the primary TPC index identifies the first TPC command in the array.

7. The wireless device of claim 6 , wherein the instructions further cause the wireless device to adjust an uplink signal transmission power of the primary PUCCH employing the first TPC command.

8. The wireless device of claim 7 , wherein a first format of the secondary TPC index indicates that one of the following is used as a TPC index value:

a number between 1 to 15; and

a number between 1 to 31.

9. The wireless device of claim 8 , wherein:

the TPC command is encoded by two bits based on the first DCI format being employed; or

the TPC command is encoded by one bit based on a second DCI format being employed.

10. The wireless device of claim 9 , wherein to receive the DCI comprises to blind decode for the DCI having a first format.

11. The wireless device of claim 10 , wherein the DCI is encoded based on employing a cyclic redundancy check.

12. The wireless device of claim 11 , wherein the instructions further cause the wireless device to activate the secondary cell by the wireless device.

13. The wireless device of claim 1 , wherein the instructions further cause the wireless device to receive an activation control element, from a base station, indicating an activation of the secondary cell.

14. The wireless device of claim 13 , wherein the cells are grouped into PUCCH groups comprising:

a primary PUCCH group comprising the primary cell with the primary PUCCH transmitted to the base station; and

a secondary PUCCH group comprising the secondary cell with the secondary PUCCH transmitted to the base station.

15. The wireless device of claim 14 , wherein:

the primary TPC index indicates a first DCI format;

the secondary TPC index indicates the first DCI format;

the secondary TPC index has a TPC index value different from that of the primary TPC index; and

the DCI is of the first DCI format.

16. The wireless device of claim 15 , wherein:

the array of TPC commands comprises the TPC command and a first TPC command; and

the primary TPC index identifies the first TPC command in the array.

17. The wireless device of claim 16 , wherein the instructions further cause the wireless device to adjust an uplink signal transmission power of the primary PUCCH employing the first TPC command.

18. The wireless device of claim 1 , wherein the primary and secondary cells are grouped into PUCCH groups comprising:

a primary PUCCH group comprising the primary cell with the primary PUCCH transmitted to a base station; and

a secondary PUCCH group comprising the secondary cell with the secondary PUCCH transmitted to the base station.

19. A system comprising:

a base station comprising:

one or more first processors; and

first memory storing first instructions that, when executed by the one or more first processors, cause the base station to:

transmit:

configuration parameters of:

 a primary cell with a primary physical uplink control channel (PUCCH); and

 a secondary cell with a secondary PUCCH;

a transmit power control (TPC) radio network temporary identifier (RNTI);

a primary TPC index of the primary PUCCH; and

a secondary TPC index of the secondary PUCCH;

transmit a downlink control information (DCI) associated with the TPC RNTI, wherein the secondary TPC index identifies a TPC command in an array of TPC commands in the DCI; and

a wireless device comprising:

one or more second processors; and

second memory storing second instructions that, when executed by the one or more second processors, cause the wireless device to:

receive the configuration parameters;

receive the DCI; and

adjust a transmission power of the secondary PUCCH based on the TPC command.

20. The wireless device of claim 19 , wherein the second instructions further cause the wireless device to detect the DCI.
