A wireless device receives from a base station, first message(s) comprising configuration parameters of a plurality of cells grouped into a plurality of groups. The plurality of groups comprise: a primary group comprising a primary cell with a primary physical uplink control channel (PUCCH) transmitted to the base station; and a secondary group comprising a first plurality of secondary cells of the plurality of cells. The first plurality of secondary cells comprise a PUCCH secondary cell with a secondary PUCCH transmitted to the base station. A second message is received that comprises parameter(s) indicating a release of fewer secondary cells than the first plurality of secondary cells. The fewer secondary cells than the first plurality of secondary cells comprise the PUCCH secondary cell. The first plurality of secondary cells in the secondary group are released in response to the parameter(s) indicating the release of the PUCCH secondary cell.
