1. A method comprising:
- receiving, by a wireless device, at least one message comprising configuration parameters of a plurality of cells comprising;
a primary cell with a primary physical uplink control channel (PUCCH) transmitted to a base station; and
a PUCCH secondary cell with a secondary PUCCH transmitted to the base station;
receiving, in subframe n, a media-access-control control element indicating activation of the PUCCH secondary cell;
starting transmission of channel state information (CSI) fields for the PUCCH secondary cell from subframe n+8+k; and
wherein k is an integer depending, at least in part, on when the PUCCH secondary cell is successfully detected by the wireless device.

Abstract
A plurality of cells comprise a PUCCH secondary cell with a secondary PUCCH. The wireless device receives, in subframe n, a media-access-control control element indicating activation of the PUCCH secondary cell. The wireless device starts transmission of channel state information (CSI) fields for the PUCCH secondary cell from subframe n+8+k. k is an integer depending, at least in part, on when the PUCCH secondary cell is successfully detected by the wireless device.

9. A method comprising:
-
receiving, by a wireless device, at least one message comprising configuration parameters of a plurality of cells, the plurality of cells grouped into a plurality of physical uplink control channel (PUCCH) groups comprising; a primary PUCCH group comprising a primary cell with a primary PUCCH; and a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH; receiving, in subframe m, a first media-access-control control element (MAC CE) indicating activation of a secondary cell in the primary PUCCH group; starting transmission of channel state information (CSI) fields of the secondary cell from subframe m+8; receiving, in subframe n, a second MAC CE indicating activation of the PUCCH secondary cell; and starting transmission of CSI fields for the PUCCH secondary cell from subframe n+8+k, wherein k is an integer depending, at least in part, on when the PUCCH secondary cell is successfully detected by the wireless device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method comprising:
-
receiving, by a wireless device from a base station, at least one message comprising configuration parameters of a plurality of cells, the plurality of cells grouped into a plurality of physical uplink control channel (PUCCH) groups comprising; a primary PUCCH group comprising a primary cell with a primary PUCCH; and a secondary PUCCH group comprising a PUCCH secondary cell with a secondary PUCCH; receiving, in subframe m, a first media-access-control control element (MAC CE) indicating activation of a plurality of secondary cells comprising; a secondary cell in the primary PUCCH group; and the PUCCH secondary cell; starting transmission of channel state information (CSI) fields of the secondary cell from subframe m+8; and starting transmission of CSI fields for the PUCCH secondary cell from subframe m+8+k, wherein k is an integer number depending, at least in part, on when the PUCCH secondary cell is successfully detected by the wireless device. - View Dependent Claims (18, 19, 20)
