A wireless device receives configuration parameters indicating positions, in a DCI, of a first bit of a first TPC command and a first bit of a second TPC command that are applicable, respectively, to a first cell and a second cell of a PUCCH group. The wireless device may transmit uplink control information in a transmission timing. The transmitting may be based on the first TPC command if the first cell is a cell for PUCCH transmission in the transmission timing. The transmitting may be based on the second TPC command if the second cell is the cell for PUCCH transmission in the transmission timing.
