1. A communication device comprising:
a memory configured to store a back-off table in which a key value is mapped to each power back-off value; and
a processor, comprising processing circuitry, configured to:
transmit the back-off table stored in the memory to an electronic device coupled to the communication device,
receive, from the electronic device, a target key value determined based on at least an expected power back-off value upon the occurrence of a target event,
back off transmission power of wireless signals transmitted through an antenna of the electronic device, based on power back-off value mapped to at least the received target key value in the backoff table when the occurrence of the target event is detected, and
change, upon detection of a release of the target event, the transmission power of the electronic device to transmission power before being backed off.
