A wireless device receives message(s) indicating: a first resource for a first uplink control channel and a second resource for a second uplink control channel of a cell. The first resource and the second resource overlap in symbol duration(s). A first power level is determined for transmission of first uplink control information via the first resource. A second power level is determined for transmission of second uplink control information via the second resource. The first power level is scaled based on a first scaling factor. The first scaling factor is determined based on a first priority of the first uplink control channel. The second power level is scaled based on a second scaling factor. The second scaling factor is determined based on a second priority of the second uplink control channel. A sum of the power levels is larger than an allowed transmission power.
