Zusammenfassung:An operating method of a wireless communications device includes identifying a modulation order and resource allocation information of a first uplink signal transmitted in a first symbol and a second uplink signal transmitted in a second symbol preceding the first symbol, controlling a difference between a supply modulator output voltage value for the first uplink signal and a supply modulator output voltage value for the second uplink signal, based on the identified order or information, and transmitting the first uplink signal, based on the controlled difference between the supply modulator output voltage values.
