1. 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 transmitted to a base station; and
a secondary PUCCH group comprising 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 a secondary cell in the secondary PUCCH group; and
starting transmission of channel state information (CSI) fields for the secondary cell from subframe n+8+k, wherein;
k is equal to zero if the activation of the PUCCH secondary cell is completed before subframe n+8; and
k is greater than 0 and depends on when the activation of the PUCCH secondary cell is completed if the activation of the PUCCH secondary cell is completed on or after subframe n+8.

Abstract
A wireless device receives, in subframe n, a media-access-control control element indicating activation of a secondary cell in a secondary physical uplink control channel (PUCCH) group. The wireless device starts transmission of channel state information (CSI) fields for the secondary cell from subframe n+8+k. k is equal to zero if the activation of the PUCCH secondary cell is completed before subframe n+8. k is greater than 0 and depends on when the activation of the PUCCH secondary cell is completed if the activation of the PUCCH secondary cell is completed on or after subframe n+8.
