determine to reconfigure the secondary cell to a PUCCH secondary cell with a secondary PUCCH;

in response to the base station determining to reconfigure the secondary cell to the PUCCH secondary cell with the secondary PUCCH, transmit at least one second message to:

release the secondary cell for a wireless device; and

add the PUCCH secondary cell for the wireless device; and

receive channel state information on the secondary PUCCH of the PUCCH secondary cell; and

the 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 at least one first message;

receive the at least one second message; and

transmit the channel state information on the secondary PUCCH of the PUCCH secondary cell.

9. The system of claim 8 , wherein the one or more parameters comprise:

a plurality of common parameters; and

a plurality of dedicated parameters.

10. The system of claim 8 , wherein the first instructions, when executed, further cause the base station to:

transmit a third message causing the release of the PUCCH secondary cell in the wireless device; and

transmit a fourth message causing configuration of the secondary cell with no PUCCH resources.

11. The system of claim 8 , wherein the first instructions, when executed, further cause the base station to:

transmit a third message causing the release of the PUCCH secondary cell in the wireless device; and

transmit a fourth message causing configuration of the secondary cell with PUCCH resources.

12. The system of claim 8 , wherein the PUCCH secondary cell is deactivated when the PUCCH secondary cell is added to the wireless device.

13. The system of claim 8 , wherein the channel state information comprises a precoding matrix indicator, a rank indicator, and a channel quality indicator.

14. 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, from a base station, at least one first message comprising one or more parameters of cells comprising a secondary cell with no configured physical uplink control channel (PUCCH);

receive at least one second message comprising parameters for reconfiguring the secondary cell to a PUCCH secondary cell with a secondary PUCCH;

release the secondary cell in response to the at least one second message;

add, after the releasing, the PUCCH secondary cell with the secondary PUCCH; and

transmit channel state information on the secondary PUCCH of the PUCCH secondary cell.

15. The wireless device of claim 14 , wherein the one or more parameters comprise:

a plurality of common parameters; and
