Abstract
One of the embodiments of the present disclosure relates to a method for adjusting peak power capability of a power amplifier circuitry. The power amplifier circuitry comprises at least one main amplifier path and at least one peak amplifier path and is configured to output a signal combining amplified signals from the at least one main amplifier path and the at least one peak amplifier path. The method comprises calculating a PAPR of an input signal of the power amplifier circuitry; determining at least one configuration parameter of the at least one peak amplifier path depending upon the calculated PAPR of the input signal; and configuring the at least one peak amplifier path based on the determined at least one configuration parameter, thereby adjusting the peak power capability of the power amplifier circuitry. The present disclosure also relates to corresponding apparatus and wireless communication devices.
