Abstract: 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.

Abstract: An electronic device for preventing or reducing damage to a radio frequency front end (RFFE). The electronic device including a memory device configured to store operating state information of a RFFE and a damage prevention condition of the RFFE, the RFFE providing a signal path for delivering a first transmission (TX) signal to an antenna, and a TX signal controller configured to generate a TX signal control signal in response to determining that the operating state information does not satisfy the damage prevention condition, the TX signal control signal causing the first TX signal to be blocked or a magnitude of the first TX signal to be reduced.

Abstract: A device for measuring a reflection coefficient of an antenna includes processing circuitry configured to extract a first feedback signal and a second feedback signal from a third feedback signal based on first symbol information of a first symbol included in a radio frequency (RF) transmit signal transferred to the antenna, the first feedback signal corresponding to at least a portion of a cyclic prefix portion of the first symbol, the second feedback signal corresponding to at least a portion of a back-end portion of the first symbol, the third feedback signal being generated from a portion of the RF transmit signal provided by a coupler, and compute the reflection coefficient based on the first feedback signal and the second feedback signal.
