Abstract: A method of adjusting a transmit power for signals in a wireless communication system is provided. A user equipment (UE) sets a first transmit power for a first signal and a second transmit power for a second signal. If a total transmit power of the first transmit power for the first signal and the second transmit power for the second signal exceeds a maximum transmit power, the UE scales the first transmit power for the first signal and the second transmit power for the second signal. The first transmit power for the first signal and the second transmit power for the second signal are scaled with a scaling factor parameter. Values of the scaling factor parameter are the same across a plurality of serving cells.
