A wireless device receives radio resource control messages indicating: a first maximum total transmit power of a first group comprising first cell(s) of a first Radio Access Technology; and a second maximum total transmit power of a second group comprising second cell(s) of a second Radio Access Technology. A first total power for transmission of first signal(s) via the first group exceeding the first maximum total transmit power is determined. First transmission power of first signal(s) are scaled so that an updated first total power does not exceed the first maximum total transmit power. Second total power for transmission of second signal(s) via the second group exceeding the second maximum total transmit power is determined. Second transmission power of second signal(s) are scaled so that an updated second total power does not exceed the second maximum total transmit power.
