In accordance with the present disclosure, disadvantages and problems associated with controlling signal transmission of a wireless communication device may be reduced. In accordance with an example embodiment of the present disclosure a method for controlling transmission of a wireless communication signal comprises sensing one or more signals indicative of a power level of a wireless communication signal. The power level of the wireless communication signal is amplified by a power amplifier according to an amplifier control signal. The method further comprises determining a change in the power level based on the one or more signals indicative of the power level. The change is associated with one or more perturbations of the amplifier control signal. The method also comprises adjusting transmission of the wireless communication signal according to the change in the power level.
