Description

Wearable electronic devices and methods for controlling transmission power in wearable electronic devices

[0001] Various embodiments of the present disclosure relate to a method for controlling transmission power in a wearable electronic device.

[0002] Electronic devices can refer to devices that perform specific functions based on embedded programs, such as home appliances, electronic notebooks, portable multimedia players, mobile communication terminals, tablet PCs, audio / video devices, desktop / laptop computers, or in-vehicle navigation systems. For example, these electronic devices can output stored information as audio or video. As electronic device integration increases and ultra-high-speed, high-capacity wireless communications become more widespread, a single electronic device, such as a mobile communication terminal, can now incorporate a variety of functions. For example, in addition to communication functions, a single electronic device can also integrate entertainment functions such as games, multimedia functions such as music / video playback, communication and security functions for mobile banking, or even functions such as schedule management and electronic wallets. These electronic devices are becoming smaller and more convenient for users to carry and wear. With the advancement of electronics and communication technologies, these devices are becoming smaller and lighter enough to be worn on the body without significant discomfort, enabling them to be provided in the form of wearable electronic devices.

[0003] A wearable electronic device can support wireless communication through a network and transmit communication signals based on transmission power values ​​for each frequency band specified in advance. When transmitting a communication signal, the wearable electronic device may be more likely to generate heat as the transmission power values ​​for each frequency band increase. When the wearable electronic device receives music data through a network and plays music, the wearable electronic device may also be more likely to generate heat due to the high data processing volume. The wearable electronic device may be configured to block transmission of communication signals (or operate in cool-down mode) when the internal temperature of the device exceeds a certain temperature due to heat generation. In addition, when transmitting a communication signal by maximizing the transmission power values ​​for each frequency band in a weak electric field and receiving music data through a network and playing music, heat generation may become severe, which may cause frequent occurrence of the operation of blocking transmission of communication signals, which may cause discomfort to the user.

[0004] According to one embodiment, a wearable electronic device and a method for controlling transmission power in a wearable electronic device can be provided that can reduce the possibility of heat generation by lowering transmission power values ​​for each frequency band when receiving music data through a network and playing music.

[0005] According to one embodiment, a wearable electronic device may include an audio output module, a communication circuit, a memory, and at least one processor. According to one embodiment, the at least one processor may identify whether a music playback function is activated based on an occurrence of a communication signal transmission event. According to one embodiment, the at least one processor may control the communication circuit to transmit the communication signal using first transmission power control information based on the deactivation of the music playback function. According to one embodiment, the at least one processor may control the communication circuit to transmit the communication signal using second transmission power control information based on the activation of the music playback function.

[0006] In one embodiment, a method for controlling transmission power in a wearable electronic device may include an operation of identifying whether a music playback function is activated based on an occurrence of a communication signal transmission event. In one embodiment, the method may include an operation of transmitting the communication signal using first transmission power control information through a communication circuit based on the deactivation of the music playback function. In one embodiment, the method may include an operation of transmitting the communication signal using second transmission power control information through the communication circuit based on the activation of the music playback function.

[0007] According to one embodiment, a non-volatile storage medium storing commands is provided, wherein the commands, when executed by an electronic device, are configured to cause the electronic device to perform at least one operation, wherein the at least one operation may include: an operation of identifying whether a music playback function is activated based on an occurrence of a communication signal transmission event; an operation of transmitting the communication signal using first transmission power control information through a communication circuit based on deactivation of the music playback function; and an operation of transmitting the communication signal using second transmission power control information through the communication circuit based on activation of the music playback function.

[0008] According to one embodiment, by receiving music data through a network and lowering the transmission power values ​​for each frequency band when playing music, the possibility of heat generation can be reduced.

These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0118] In operation 720, at least one processor (420, 491) according to an embodiment may identify whether a power back-off condition associated with SAR is satisfied. According to an embodiment, SAR is a numerical value indicating how much electromagnetic waves radiated from a wearable electronic device (101 or 401) are absorbed by the human body.
