A wireless device receives a media access control (MAC) activation command indicating activation of a plurality of physical uplink control channel (PUCCH) secondary cell. The wireless device receives, on a secondary cell in the plurality of cells, downlink control information comprising a PUCCH transmit power control (TPC) command. The wireless device calculates, a transmit power of the secondary PUCCH, employing the PUCCH TPC command only if the secondary PUCCH group comprises the secondary cell. The wireless device transmits uplink signals on the secondary PUCCH with the transmit power.
