Description

[Technical Field] Various embodiments of the disclosure relate to a method for controlling transmission power in a wearable electronic device. [Background Art] An electronic device may refer to a device that performs specific functions based on a built-in program, such as a home appliance, an electronic organizer, a portable multimedia player, a mobile communication terminal, a tablet PC, a video/audio device, a desktop/laptop computer, or a vehicle navigation device. For example, these electronic devices may output stored information as sound or video. As electronic devices have become more integrated and ultrahigh-speed, large-capacity wireless communication has become commonplace, a single electronic device, such as a mobile communication terminal, may now be equipped with various functions. For example, not only communication functions but also entertainment functions like gaming, multimedia functions like music/video playback, communication and security functions for mobile banking, and various other functions like schedule management or an e-wallet are all integrated into a single electronic device. These electronic devices are miniaturized so that users may conveniently carry and wear them. Along with the development of electronics and communication technology, these electronic devices are miniaturized and lightened to the point where they may be used while worn on the body without great discomfort, and thus may be provided in the form of a wearable electronic device. [Detailed Description of the Invention] [Technical Solution] A wearable electronic device may support wireless communication over a network and transmit a communication signal based on a pre-specified transmission power value for each frequency band. As the transmission power values for each frequency band increases during transmission of a communication signal, when the wearable electronic device may have a higher likelihood of heat generation. When the wearable electronic device receives music data via the network and plays music, there is also a higher possibility of heat generation due to a high data throughput. When the internal temperature of the wearable electronic device is equal to or higher than a specific level due to heat generation, it may be configured to block the transmission of communication signals (or operate in a cool-down mode). When the wearable electronic device receives music data over the network and plays music, while performing communication signal transmission with a maximum transmission power value for each frequency band in a weak electric field, heat generation becomes severe. This may cause the communication signal transmission blocking operation to occur frequently, which may cause user inconvenience. According to an embodiment, a wearable electronic device and a method for controlling transmission power in the wearable electronic device may be provided, which may reduce a likelihood of heat generation by reducing a transmission power value for each frequency band during reception of music data through a network and music playback.
