Abstract
Description
Technical Field
[0001] Various embodiments of this disclosure relate to a method for controlling transmission power in a wearable electronic device. Background Technology
[0002] Electronic devices can refer to devices that perform specific functions based on built-in programs, such as home appliances, electronic notebooks, portable multimedia players, mobile communication terminals, tablet PCs, video / audio devices, desktop / laptop computers, or vehicle navigation devices. For example, these electronic devices can output stored information as sound or video. As electronic devices have become more integrated and ultra-high-speed, high-capacity wireless communication has become commonplace, individual electronic devices (such as mobile communication terminals) can now be equipped with a wide variety of functions. For example, not only communication functions, but also entertainment functions (such as games), multimedia functions (such as music / video playback), mobile banking communication and security functions, and various other functions (such as schedule management or e-wallets) are integrated into a single electronic device. These electronic devices are miniaturized, making them convenient for users to carry and wear. With the development of electronic and communication technologies, these electronic devices have been miniaturized and lightweighted to the point that they can be used when worn on the body without much discomfort, and therefore can be provided in the form of wearable electronic devices. Summary of the Invention
[0003] Technical solution Wearable electronic devices support wireless communication over a network and transmit communication signals based on a pre-specified transmission power value for each frequency band. As the transmission power value for each frequency band increases during communication signal transmission, the wearable electronic device may have a higher likelihood of generating heat. When the wearable electronic device receives and plays music data over a network, there is also a high likelihood of heat generation due to the high data throughput. When the internal temperature of the wearable electronic device reaches or exceeds a certain level due to heat, the wearable electronic device can be configured to block communication signal transmission (or operate in a cooling mode). When the wearable electronic device receives and plays music data over a network, heat generation becomes severe when transmitting communication signals at the maximum transmission power value for each frequency band in a weak electric field. This may lead to frequent communication signal transmission blocking operations, which could cause inconvenience to the user.
[0004] According to an embodiment, a wearable electronic device and a method for controlling transmission power in the wearable electronic device can be provided, which can reduce the likelihood of heat generation by reducing the transmission power value for each frequency band during music data reception and music playback over a network.
[0005] The wearable electronic device according to an embodiment may include a sound output module, a communication circuit, a memory, and at least one processor. The at least one processor according to an embodiment may identify whether a music playback function is activated based on the occurrence of an event for transmitting a communication signal. The at least one processor according to an embodiment may control the communication circuit to transmit a communication signal using first transmission power control information based on the deactivation of the music playback function. The at least one processor according to an embodiment 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] According to an embodiment, a method for controlling transmission power in a wearable electronic device may include: identifying whether a music playback function is activated based on the occurrence of an event for transmitting a communication signal. The method according to an embodiment may include: transmitting a communication signal via a communication circuit using first transmission power control information based on the deactivation of the music playback function. The method according to an embodiment may include: transmitting the communication signal via the communication circuit using second transmission power control information based on the activation of the music playback function.
[0007] According to embodiments of this disclosure, in a non-transitory storage medium storing instructions, the instructions can be configured to cause the electronic device to perform at least one operation when executed by the electronic device. The at least one operation may include: identifying whether a music playback function is activated based on the occurrence of an event for transmitting a communication signal; transmitting a communication signal via a communication circuit using first transmission power control information based on the deactivation of the music playback function; and transmitting the communication signal via the communication circuit using second transmission power control information based on the activation of the music playback function.
[0008] According to an embodiment, the likelihood of heat generation can be reduced by decreasing the transmission power value for each frequency band during music data reception and playback over the network. Attached Figure Description

These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components separate from each other (e.g., multiple chips). The wireless communication module 192 can identify and verify the electronic device 101 in the communication network (such as the first network 198 or the second network 199) using user information (e.g., the International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196.

SAR uses units of kW / g or mW / g, where kW / g or mW / g can refer to the amount of power (kW, W, or mW) absorbed by the human body per gram. According to an embodiment, a SAR-related power back-off condition can be a condition where the expected SAR from the transmitted power exceeds a threshold. For example, a SAR-related power back-off condition may include the following conditions: a microphone or speaker is in use during a call connection, and the country code associated with the communication corresponding to the call connection is a designated MCC.
[0118] In operation 730, when the SAR-related power back-off condition is met, at least one processor 420 and 491 according to the embodiment can control the communication signal to be transmitted using third transmit power control information, regardless of whether the music playback function is activated. The third power control information according to the embodiment may include information for adjusting a specified maximum transmit power level for each frequency band to a level corresponding to the SAR-related power back-off condition.
[0119] The third transmit power control information according to the embodiment may include information such as Table 3 below.
[0120] [Table 3]
[0121] Referring to Table 3, the BAND according to the embodiment can be frequency band identification information. The Power control according to the embodiment can be power control information for each frequency band. For example, BAND: 2, Power control: -4 can be control information that reduces the power of the frequency band corresponding to 2 by -4dB. BAND: 4, Power control: 0 can be information indicating that the power of the frequency band corresponding to 4 is not adjusted. BAND: 5, Power control: -5 can be control information that reduces the power of the frequency band corresponding to 5 by -5dB. BAND: 12, Power control: 0 can be information indicating that the power of the frequency band corresponding to 12 is not adjusted. BAND: 13, Power control: -4 can be control information that reduces the power of the frequency band corresponding to 13 by -4dB. Table 3 only describes one example of power adjustment, and it is obvious that, based on experiments regarding the relationship between the transmit power level and SAR for each frequency band of wearable electronic device 101 or wearable electronic device 401, the control information values can be set to various other values. In operation 740, when the SAR-related power back-off condition is not met, at least one processor 420 and 491 according to the embodiment can identify whether the music playback function is activated. At least one processor 420 and 491 according to the embodiment can identify whether the music playback function is activated based on an interrupt related to audio processing (or audio data blocks in memory 430). At least one processor 420 and 491 according to the embodiment can identify whether the music playback function is activated based on a media session created by executing a music playback application or a music streaming application. Application processor 420 according to the embodiment can identify whether the music playback function is activated based on an interrupt related to audio processing (or audio data blocks in memory 430) when the SAR-related power back-off condition is not met. In operation 750, when the music playback function is disabled, at least one processor 420 and 491 according to the embodiment can control communication circuit 493 to transmit communication signals using first transmit power control information. The first transmit power control information according to an embodiment may include information that causes the communication circuit 493 to use a specified transmit power level or MTPL (e.g., 23 dBm in the 3GPP communication standard) for each frequency band. For example, the first transmit power control information may include transmit power control information for normal operation (e.g., a normal transmit power control table (or a default transmit power control table)). The first transmit power control information according to an embodiment may include information such as Table 1 described above.
[0122] In operation 760, when the music playback function is active, at least one processor 420 and 491 according to the embodiment can obtain music playback time information. At least one processor 420 and 491 according to the embodiment can continuously (or periodically) check the music playback time while the music playback function is active, and obtain the cumulative music playback time from the start time of the music playback to the current time.
[0123] In operation 770, at least one processor 420 and 491 according to the embodiment can identify intervals including music playback time. With the music playback time interval set to a specified time unit (e.g., 5 minutes), at least one processor 420 and 491 according to the embodiment can identify intervals including music playback time. The music playback time unit (or interval) can be set to different time units between several minutes and tens of minutes.
[0124] In operation 780, at least one processor 420 and 491 according to the embodiment can control the communication circuit 493 to transmit communication signals using intervals including music playback time and second transmission power control information (e.g., the second transmission power control information in Table 2).
[0125] Figure 8a This is a graph showing the peak current when the second transmit power control information according to the music playback function is not applied in the wearable electronic device, according to an embodiment. Figure 8b This is a graph showing the peak current when second transmit power control information is applied to the wearable electronic device according to an embodiment of the music playback function activation.
[0126] Reference Figure 8a In the first peak current curve 810 according to the embodiment, the horizontal axis can represent time (s) and the vertical axis can represent current (mA). When the music playback function is activated when the SAR-related power back-off condition is not met, and the wearable electronic device (e.g., Figure 1 Electronic device 101, or Figure 4 At least one processor (e.g., in the wearable electronic device 401) Figure 1 The processor 120 and wireless communication module 192 in the middle, or Figure 4 When the application processor 420 and the communication processor 491 in the middle perform a transmission operation using the first transmission power control information for normal state during music playback, as shown in the first peak current curve 810, a current peak 812 higher than the reference current may occur, which may increase the thermal temperature, thus causing the cooling mode to occur frequently due to heat generation.
[0127] Reference Figure 8bIn the second peak current curve 820 according to the embodiment, the horizontal axis can represent time (s) and the vertical axis can represent current (mA). When the music playback function is activated when the SAR-related power back-off condition is not met, and the wearable electronic device (e.g., Figure 1 Electronic device 101, or Figure 4 At least one processor (e.g., in the wearable electronic device 401) Figure 1 The processor 120 and wireless communication module 192 in the middle, or Figure 4 When the application processor 420 and communication processor 491 perform a transmission operation using the second transmission power control information during music playback, as shown in the second peak current curve 820, a second current peak 814 lower than the first current peak 812 or the reference current may occur. Compared with the state of the first peak current curve 810, this can reduce the thermal temperature and reduce the number of cooling modes caused by heat generation.
[0128] When the music playback function is activated when the SAR-related power back-off condition is not met, and wearable electronic devices (e.g., Figure 1 Electronic device 101, or Figure 4 When the wearable electronic device 401 uses the second transmit power control information during music playback, the call hold time (e.g., the call hold time associated with the music stream) can be increased compared to when the second transmit power control information is not used.
[0129] Table 4 below shows the average current, call hold time, and temperature (e.g., rear temperature) of the wearable electronics during music streaming under weak network conditions, when the wearable electronics 401 does not use the second transmit power control information and when the wearable electronics 401 uses the second transmit power control information.
[0130] [Table 4]
[0131] Referring to Table 4, when music streaming is performed and music playback is activated because the SAR-related power back-off condition is not met, the wearable electronic device according to the embodiment (e.g., [example]) performs better than when the second transmit power control information is not used. Figure 1 Electronic device 101, or Figure 4The wearable electronic device 401 can increase call hold time (e.g., call hold time associated with music streaming), thereby extending network connectivity usage time, and delay entering cooling mode during music playback, while maintaining similar average current and temperature during cooling in either the first or second case when using second transmit power control information during music playback.
