ADAPTIVE TRANSMISSION SIGNAL POWER ADJUSTMENT METHOD, AND ELECTRONIC DEVICE THEREFOR

WIPO Patent Application WO/2022/019564

A1

According to one or more embodiments of the present invention, an electronic device comprises: a digital block which processes an input signal and outputs a base band digital signal; an analog block which converts the base band digital signal into an analog signal and processes the converted analog signal to convert the same into a radio frequency (RF) signal; and an antenna module which amplifies the RF signal and outputs an amplified transmission signal. The digital block can determine whether the output waveform of the transmission signal output through the antenna module is a first waveform or a second waveform, adjust the level of the base band digital signal on the basis of a first backoff value if the output waveform is the first waveform, and adjust the level of the base band digital signal on the basis of a second backoff value if the output waveform is the second waveform. In addition, one or more other embodiments may be possible.
