Abstract: An apparatus for controlling an Uplink (UL) power in a wireless communication system including a transmitter/receiver and a controller may be provided. The transmitter/receiver may receive/decode Downlink (DL) data, transmit a feedback signal with respect to the DL data, and receive Transmit power Control (TPC) commands from active set cells including a serving cell. The controller may decode the TPC commands to generate a combined TPC command, in which decoded TPC commands of the active set cells are combined, and calculate a transmission error rate of an UL feedback transmission signal and a requested rate of transmit power increase of the serving cell, determine a transmit power gain offset and the requested rate of transmit power increase, determine an UL power for transmitting a feedback signal with respect to the received DL data based on the transmit power gain offset, and transmit the feedback signal based on the UL power.

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.
