Embodiments herein include a method of controlling the total power with which a radio transmitter of a radio access node transmits a signal. The method entails inputting an input signal into a power amplifier of the radio transmitter to produce, as a function of the input signal, an output signal to be transmitted by the radio transmitter. The method further entails generating a feedback signal from the output signal at the radio transmitter, and measuring that feedback signal to obtain one or more performance metrics that characterize performance of the output signal. The method finally includes comparing the one or more performance metrics to one or more performance metric thresholds, and controlling a maximum permissible level of the total power of the input signal, based on that comparison.
