Electronic device and method for controlling transmission power thereof

An electronic device comprising:

• a housing;
• a flexible display;
• a support structure configured to roll the flexible display;
• a wireless communication circuit disposed inside the housing;
• a grip sensor;
• at least one sensor configured to detect a unfolding degree of the flexible display;
• a processor disposed inside the housing, and operably connected to the flexible display, the wireless communication circuit, the grip sensor, and the at least one sensor;
• and
• a memory operably connected to the processor, wherein the memory stores instructions that, when executed, cause the processor to:
• determine, using the at least one sensor, the unfolding degree of the flexible display;
• detect, using the grip sensor, an approach distance between an external object and the electronic device;
• and
• adjust a transmission power of the wireless communication circuit based at least in part on the unfolding degree and the approach distance.

A method for controlling transmission power of an electronic device, the method comprising:

• determining an effective size of an exposed area of a flexible display of the electronic device;
• determining a type of the electronic device based at least in part on the determined effective size;
• detecting a distance between the electronic device and an external object;
• and
• adjusting transmission power of a wireless communication circuit of the electronic device based at least in part on the determined type of the electronic device and the detected distance,
• wherein adjusting the transmission power of the wireless communication circuit comprises selecting at least one of a plurality of parameters stored for adjusting the transmission power based at least in part on the determined type of the electronic device and the detected distance.
