Summary:A communication apparatus, according to one embodiment, may comprise: a memory which stores a back-off table mapped with a key value for each power back-off value; and a processor which transmits the back-off table stored in the memory to an electronic device combined with the communication apparatus, receives, from the electronic device, a target key value determined based on a predicted power back-off value required depending on the occurrence of a target event, and when the occurrence of the target event is sensed, based on the power back-off value mapped with the target key value received from the back-off table, backs-off a transmitting power of a wireless signal transmitting through an antenna of the electronic device. According to embodiments of the present invention, the apparatus can lower a transmitting power of a wireless signal to a critical power or less, without separate management of power values requiring back-offs for each manufacturer. 일 실시예에 따른 통신 장치는, 전력 백오프 값(power back-off value)들 별로 키 값(key value)이 매핑된 백오프 테이블(back-off table)을 저장한 메모리, 및 통신 장치와 결합된 전자 기기에게 메모리에 저장된 백오프 테이블을 전송하고, 전자 기기로부터 대상 이벤트의 발생에 따라 요구되는 예상 전력 백오프 값에 기초하여 결정된 대상 키 값을 수신하고, 대상 이벤트의 발생을 감지하는 경우 백오프 테이블에서 수신된 대상 키 값과 매핑된 전력 백오프 값에 기초하여 전자 기기의 안테나를 통해 송신되는 무선 신호의 송신 전력을 백오프(back-off)하는 프로세서를 포함할 수 있다.
