MODE FOR THE INVENTION

A power supply voltage of an amplifier may be measured by implementing a voltage distribution circuit including a resistance element between the amplifier and a modulator that supplies power to the amplifier, and sensing a power supply voltage node of the amplifier by using the voltage distribution circuit.

However, a method for measuring the power supply voltage of the amplifier by using the voltage distribution circuit may increase a manufacturing cost of an electronic device because of the implementation of the voltage distribution circuit and/or the resistance element included in the voltage distribution circuit, and may act as a constraint on an internal space of the electronic device that is sensitive to integration. In addition, in routing the voltage distribution circuit to the power supply voltage node of the amplifier, when the length of the voltage distribution circuit increases, the power supply voltage of the amplifier may drop and thus the reliability of a measured value may be deteriorated.

Embodiments of the disclosure may present a method and device that may compensate for a transmission power level of a Tx signal based on a voltage level of a battery.

Various embodiments of the disclosure are described below with reference to the accompanying drawings. However, these are not intended to limit the disclosure to specific embodiment forms, and should be understood as including various modifications, equivalents, and/or alternatives of the embodiments of the disclosure.

The communication module 190 may include one or more communication processors that are operable independently from the processor 120 (e.g., the application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module 192 may identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

The wireless communication module 192 may support a 5G network, after a 4G network, and next-generation communication technology, e.g., new radio (NR) access technology.

The antenna module 197 may transmit or receive a signal or power to or from the outside (e.g., the external electronic device) of the electronic device 101. According to an embodiment, the antenna module 197 may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)).

According to an embodiment, the mmWave antenna module may include a printed circuit board, a RFIC disposed on a first surface (e.g., the bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high-frequency band (e.g., the mm Wave band), and a plurality of antennas (e.g., array antennas) disposed on a second surface (e.g., the top or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving signals of the designated high-frequency band.

At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)).

According to an embodiment, commands or data may be transmitted or received between the electronic device 101 and the external electronic device 104 via the server 108 coupled with the second network 199. Each of the electronic devices 102 or 104 may be a device of a same type as, or a different type, from the electronic device 101. According to an embodiment, all or some of operations to be executed at the electronic device 101 may be executed at one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service.

In addition, for example, the electronic device 101 may further include at least one modulator (e.g., first modulator 410 and/or second modulator 430 of FIG. 4 or FIG. 6) for supplying a driving power supply to each of the at least one power amplification module 420 and/or 440. In addition, for example, the electronic device 101 of FIG. 2 may further include at least some of the components included in the electronic device (e.g., electronic device 101 of FIG. 1) mentioned through FIG. 1.

In an embodiment, the battery 210 may be electrically connected to the components of the electronic device 101 and may supply power to the components or may be charged based on power supplied wired or wirelessly from an external power source (e.g., wall power source, auxiliary battery device, wireless charging pad, computer, and/or smartphone). In an embodiment, the battery 210 may include a protection circuit module which performs various functions and decreases the performance degradation or damage of the battery 210.

In an embodiment, the power management module 220 may be electrically connected to the battery 210 and may control the overall power management of the electronic device 101. For example, the power management module 220 may charge the battery 210 by using power supplied from the external power source. In this operation, the power management module 220 may determine a method (e.g., normal charging or rapid charging) for charging the battery 210 based on at least one of the type of the external power source, the magnitude of power supplied from the external power source, or the properties of the battery 210. In addition, for example, the power management module 220 may adjust the power of the battery 210 to a voltage level or current level suitable for each component of the electronic device 101 and supply the adjusted power to the corresponding component. According to an embodiment, the power management module 220 may include a power management integrated circuit (PMIC) including at least one buck converter. In an embodiment, the power management module 220 may include a fuel gauge integrated circuit (IC) 221. In an embodiment, the fuel gauge IC 221 may monitor the battery 210 and measure status information (e.g., available capacity, number of charges, number of discharges, lifespan, voltage, and/or temperature) of the battery 210.

In an embodiment, the second processor 230 may be electrically connected to components of the electronic device 101 and may execute and control various functions supported by the electronic device 101. For example, the second processor 230 may execute a code of a programming language stored in a memory (e.g., memory 130 of FIG. 1) and may control the function and/or operation of the electronic device 101 component, or may perform various processing on signals and/or data transmitted from the component. In an embodiment, the second processor 230 may include an application processor (e.g., main processor 121 of FIG. 1).

In an embodiment, the communication module 240 may support wired communication or wireless communication between the electronic device 101 and at least one external device (e.g., communication network operator server and/or external electronic device). In an embodiment, the communication module 240 may include a first processor 241 and a transceiver 243 that can be, but are not required to be, formed as a single chip or a single package with the communication module 240. In an embodiment, the first processor 241 may include a communication processor (e.g., auxiliary processor 123 of FIG. 1), and may establish communication being based on a stipulated protocol with the at least one external device, and may control transmission and reception of signals and/or data through the established communication. In an embodiment, the transceiver 243 may support transmission of a Tx signal and reception of an Rx signal, and may convert a baseband signal into a radio frequency (RF) signal that may be used for communication with the at least one external device when transmitting the Tx signal, and may convert an RF signal into a baseband signal that may be processed by the first processor 241 when receiving the Rx signal. In an embodiment, the transceiver 243 may include a power amplification module (or power amplification circuit) for increasing (or amplifying) a transmission power level of a Tx signal to be output from the transceiver 243, and may further include an RF driver which controls the operation of the power amplification module.

FIG. 3 is a flow diagram illustrating a method for compensating for a transmission power of a signal according to an embodiment. FIG. 4 is a schematic diagram illustrating an operational relationship between components related to compensation for a transmission power of a signal according to an embodiment.

In describing the embodiment of FIG. 3 below, the embodiment of FIG. 4 may be referred to together. In addition, the operations mentioned in the embodiment of FIG. 3 may be performed sequentially, but may not necessarily be performed sequentially. For example, the order of the operations mentioned in the embodiment of FIG. 3 may be changed, or at least two operations may be performed in parallel.

Referring to FIGS. 3 and 4, in operation 310, the first processor 241 (e.g., communication processor) may detect a transmission event of a Tx signal. For example, when data communication of the electronic device 101 based on at least one of a circuit switching method and a packet switching method is detected, the first processor 241 may determine that the transmission event of the Tx signal has occurred. However, the data communication based on at least one of the circuit switching method and the packet switching method is one example, and the disclosure is not limited to the data communication of this method. For example, the transmission event of the Tx signal may be detected in various communication environments in which the transmission of the Tx signal is involved.

In various embodiments, the first processor 241 may detect the occurrence of the transmission event of the Tx signal at a time when the data communication is actually performed, or may detect the occurrence of the transmission event of the Tx signal at a time when an application supporting the data communication is executed. In an embodiment, in response to detecting the transmission event of the Tx signal, the first processor 241 may determine whether an interface supporting the transmission of data and/or signals exists between the first processor 241 and the power management module 220.

In an embodiment, in operation 320, the first processor 241 may request status information about the battery 210 from the second processor 230 (e.g., application processor) based on detecting the transmission event of the Tx signal and determining that no interface with the power management module 220 exists. In this regard, the first processor 241 may be electrically connected to the second processor 230 via an inter process communication (IPC) interface, and the first processor 241 may request voltage level information about the battery 210 from the second processor 230 via the IPC interface.

In an embodiment, the first processor 241 may repeatedly perform the request for the voltage level information about the battery 210 of operation 320 according to a specified period while the transmission event of the Tx signal is maintained. In an embodiment, the specified period may be determined based on the voltage level information about the battery 210 when the voltage level information about the battery 210 requested by the first processor 241 is obtained (or received) from the second processor 230. For example, the first processor 241 may determine the specified period as a first period (e.g., one minute) based on the obtained voltage level information about the battery 210 indicating a voltage level being within a preset low voltage level range. Also, for example, the first processor 241 may determine the specified period as a second period (e.g., five minutes) longer than the first period based on the obtained voltage level information about the battery 210 indicating a voltage level being within a preset high voltage level range. In an embodiment, the determined first period or second period may be adaptively changed according to the voltage level information about the battery 210 obtained by the first processor 241. For example, the first processor 241 may request the voltage level information about the battery 210 according to the second period based on the voltage level information about the battery 210 obtained according to the first period indicating the voltage level being within the high voltage level range.

According to an embodiment, in operation 330, in response to the request of the first processor 241, the second processor 230 may obtain (or receive) the voltage level information about the battery 210 from the fuel gauge IC 221 of the power management module 220 electrically connected thereto. For example, the second processor 230 may access the power management module 220 and may read a voltage level of the battery 210 measured by the fuel gauge IC 221 of the power management module 220, or may request the voltage level information about the battery 210 from the power management module 220 and may receive the voltage level information about the battery 210.

According to an embodiment, in operation 340, the second processor 230 may present the obtained voltage level information about the battery 210 to the first processor 241 through the IPC interface. Thus, the first processor 241 may obtain the voltage level information about the battery 210 requested from the second processor 230.

According to an embodiment, in operation 350, the first processor 241 may present the obtained voltage level information about the battery 210 to the transceiver 243. For example, the first processor 241 may transmit the voltage level information about the battery 210 to an RF driver of the transceiver 243 that is optionally configured as a single chip or single package with the first processor 241.

According to an embodiment, in operation 360, the transceiver 243 may compensate for a transmission power level of a Tx signal to be transmitted from the electronic device 101 according to a transmission event of the Tx signal based on the voltage level information about the battery 210 presented from the first processor 241. For example, the RF driver of the transceiver 243 may determine a compensation value for the transmission power level of the Tx signal by using Equation 1 below.

$\begin{matrix} Compensation value = (reference voltage level - battery voltage level) \times NV data value & [Equation 1] \end{matrix}$

According to an embodiment, the RF driver of the transceiver 243 may apply a voltage level of the battery 210 as a variable to Equation 1. For example, the RF driver of the transceiver 243 may determine a compensation value for compensating for the transmission power level of the Tx signal by performing a series of calculation processes of subtracting the voltage level of the battery 210 applied as the variable from a preset reference voltage level and then multiplying a data value (e.g., NV data value) previously stored in a non-volatile (NV) area of a memory (e.g., non-volatile memory 134 of FIG. 1) based on Equation 1.

In an embodiment, the reference voltage level may be set to a high voltage level (e.g., voltage level between about 3.8 V and about 3.9 V). Based on this, when the voltage level information about the battery 210 indicates a high voltage level, the compensation value for the transmission power level of the Tx signal calculated from Equation 1 may be determined to be a relatively small first magnitude. Conversely, when the voltage level information about the battery 210 indicates a low voltage level, the compensation value for the transmission power level of the Tx signal calculated from Equation 1 may be determined as a relatively large second magnitude (or a second magnitude greater than the first magnitude). In various embodiments, the reference voltage level and the NV data value may be recorded as binary data in a memory (e.g., nonvolatile memory 134 of FIG. 1) of the electronic device 101, and may be changed according to the properties (e.g., model, specifications, and/or battery 210 capacity) of the electronic device 101.

In addition, for example, the RF driver of the transceiver 243 may determine the compensation value for the transmission power level of the Tx signal by using a lookup table stored in the memory (e.g., memory 130 of FIG. 1) of the electronic device 101. In this regard, the memory 130 may store the lookup table in which a corresponding compensation value is defined for each voltage level of the battery 210. In an embodiment, when the RF driver of the transceiver 243 receives the voltage level information about the battery 210 from the first processor 241, the RF driver of the transceiver 243 may determine a compensation value corresponding to a voltage level of the battery 210 with reference to the lookup table of the memory 130. In an embodiment, the compensation value determined from the lookup table may be determined as the relatively small first magnitude when the voltage level information about the battery 210 indicates the high voltage level, and may be determined as the relatively large second magnitude (or the second magnitude larger than the first magnitude) when the voltage level information about the battery 210 indicates the low voltage level.

In an embodiment, the RF driver of the transceiver 243 may control a power amplification module (or power amplification circuit) included in the transceiver 243 to increase a transmission power level of a Tx signal by the determined compensation value based on determining the compensation value corresponding to the voltage level of the battery 210 by using Equation 1 or the lookup table.

In an embodiment, the Tx signal whose transmission power level is increased (or compensated) by the power amplification module of the transceiver 243 may be output from the transceiver 243 and input to the first power amplification module 420 or to the second power amplification module 440. For example, the Tx signal output from the transceiver 243 may be input to the first power amplification module 420 for processing of a signal of a first frequency band (e.g., low frequency band) or the second power amplification module 440 for processing of a signal of a second frequency band (e.g., intermediate frequency band and high frequency band) in accordance with a frequency band of the Tx signal. In an embodiment, each of the first power amplification module 420 and the second power amplification module 440 may include at least one of a low noise amplifier, a power amplifier, and a duplexer, and may increase the transmission power level of the Tx signal that is input from the transceiver 243.

In an embodiment, the transmission power level of the Tx signal to be transmitted from the electronic device 101 according to the occurrence of a transmission event of the Tx signal may be first increased (or compensated) in the transceiver 243 based on the voltage level information about the battery 210, and may be input from the transceiver 243 to the first power amplification module 420 or the second power amplification module 440 and be secondly increased (or compensated). In this regard, the first power amplification module 420 and the second power amplification module 440 may have a limited gain capability (or uncontrollable gain) in increasing the transmission power level of the Tx signal, and, when the transmission power level of the Tx signal is not increased (or compensated) by the transceiver 243, the transmission power level of the Tx signal increased (or compensated) by the first power amplification module 420 or second power amplification module 440 may not be satisfied with a specified (or intended) level. Therefore, in order for the Tx signal to be transmitted from the electronic device 101 at a specified transmission power level, the transmission power level of the Tx signal may be first increased by the transceiver 243 and may be secondarily increased by the first power amplification module 420 or by the second power amplification module 440. In an embodiment, the first power amplification module 420 and the second power amplification module 440 may be electrically connected to the first modulator 410 and to the second modulator 430 based on an envelope tracking (ET) interface or on an average power tracking (APT) interface, respectively, and may receive a driving power supply.

In an embodiment, the first processor 241 may detect that the transmission event of the Tx signal is terminated. For example, when the data communication of the electronic device 101 is not performed for a specified period of time or when the execution of an application related to the data communication that was being executed is terminated, the first processor 241 may determine that the transmission event of the Tx signal is terminated. In an embodiment, even when the transmission event of the Tx signal is terminated, the first processor 241 may obtain the voltage level information about the battery 210. In this regard, the first processor 241 may determine a period for requesting (or obtaining or receiving) the voltage level information about the battery 210 while the termination of the transmission event of the Tx signal is maintained based on the voltage level information about the battery 210 that is requested and obtained from the second processor 230 after the termination of the transmission event of the Tx signal. For example, the first processor 241 may determine the period as a third period (e.g., ten minutes) based on the voltage level information about the battery 210 obtained from the second processor 230 after the termination of the transmission event of the Tx signal indicating a voltage level being within a preset low voltage level range. Also, for example, the first processor 241 may determine the period as a fourth period (e.g., thirty minutes) longer than the third period based on the voltage level information about the battery 210 obtained from the second processor 230 after the termination of the transmission event of the Tx signal indicating a voltage level being within a preset high voltage level range.

FIG. 6 is a schematic diagram illustrating another operational relationship between components related to compensation for a transmission power of a signal according to an embodiment.

In describing the embodiment of FIG. 5 below, the embodiment of FIG. 6 may be referred to together. In addition, the operations mentioned in the embodiment of FIG. 5 may be performed sequentially, but may not necessarily be performed sequentially. For example, the order of the operations mentioned in the embodiment of FIG. 5 may be changed, or at least two operations may be performed in parallel.

In addition, at least some of the operations of the electronic device described through FIGS. 5 and 6 may be identical or similar to the operations of the electronic device described through FIGS. 3 and 4 above, and any repeated descriptions of the identical or similar operations of the electronic devices may be omitted or be briefly described below.

Referring to FIGS. 5 and 6, in operation 510, the first processor 241 (e.g., communication processor) may detect a transmission event of a Tx signal. For example, when the first processor 241 detects data communication of the electronic device 101 being based on at least one of a circuit switching method and a packet switching method, the first processor 241 may determine that the transmission event of the Tx signal has occurred. In an embodiment, in response to detecting the transmission event of the Tx signal, the first processor 241 may determine whether an interface supporting transmission of data and/or signals exists between the first processor 241 and the power management module 220.

In an embodiment, in operation 520, the first processor 241 may obtain status information about the battery 210 from the power management module 220 based on the detection of the transmission event of the Tx signal and the existence of the interface with the power management module 220. For example, the first processor 241 may access the power management module 220 and may read a voltage level of the battery 210 measured by the fuel gauge IC 221 of the power management module 220, or may request and may receive voltage level information about the battery 210 from the power management module 220.

In an embodiment, the first processor 241 may repeatedly perform acquisition of the voltage level information about the battery 210 of operation 520 according to a specified period while the transmission event of the Tx signal is maintained. In an embodiment, the specified period may be determined based on the voltage level information about the battery 210 obtained by the first processor 241. For example, the first processor 241 may determine the specified period as a first period (e.g., one minute) based on the obtained voltage level information about the battery 210 indicating a voltage level being within a preset low voltage level range. In addition, for example, the first processor 241 may determine the specified period as a second period (e.g., five minutes) longer than the first period based on the obtained voltage level information about the battery 210 indicating a voltage level being within a preset high voltage level range. In an embodiment, the determined first period or second period may be adaptively changed based on the voltage level information about the battery 210 obtained by the first processor 241.

According to an embodiment, in operation 530, the first processor 241 may transmit the obtained voltage level information about the battery 210 to the transceiver 243. For example, the first processor 241 may transmit the voltage level information about the battery 210 to the RF driver of the transceiver 243.

According to an embodiment, in operation 540, the transceiver 243 may compensate for a transmission power level of the Tx signal to be transmitted from the electronic device 101 according to the transmission event of the Tx signal based on the voltage level information about the battery 210 presented from the first processor 241. For example, the RF driver of the transceiver 243 may determine a compensation value corresponding to a voltage level of the battery 210 by using Equation 1 or the lookup table referred to above, and may control the power amplification module (or power amplification circuit) of the transceiver 243 to increase (or compensate for) the transmission power level of the Tx signal by the determined compensation value.

In an embodiment, the first processor 241 may detect that the transmission event of the Tx signal is terminated. For example, when the data communication of the electronic device 101 is not performed for a specified period of time or when the execution of an application related to the data communication that was being executed is terminated, the first processor 241 may determine that the transmission event of the Tx signal is terminated. In an embodiment, the first processor 241 may obtain voltage level information about the battery 210 even after the transmission event of the Tx signal is terminated. For example, the first processor 241 may obtain the voltage level information about the battery 210 according to a third period (e.g., ten minutes) while the termination of the transmission event of the Tx signal is maintained based on the voltage level information about the battery 210 obtained from the power management module 220 after the termination of the transmission event of the Tx signal indicating a voltage level being within a preset low voltage level range. Also, for example, the first processor 241 may obtain the voltage level information about the battery 210 according to a fourth period (e.g., thirty minutes) while the termination of the transmission event of the Tx signal is maintained based on the voltage level information about the battery 210 obtained from the power management module 220 after the termination of the transmission event of the Tx signal indicating a voltage level being within a preset high voltage level range.

FIG. 7 is a schematic diagram for explaining a relationship between a battery voltage and a power supply voltage of a power amplification module according to an embodiment.

Referring to FIG. 7, a battery (e.g., battery 210 of FIG. 2, FIG. 4, or FIG. 6) of an embodiment may supply power to a modulator 710 (e.g., first modulator 410 and/or second modulator 430 of FIG. 4 or FIG. 6) that supplies a driving power supply to a power amplification module 720 (e.g., first power amplification module 420 and/or to a second power amplification module 440 of FIG. 4 or FIG. 6). For example, the power of the battery 210 may be supplied to the power amplification module 720 based on the operation of a switch 711 included in the modulator 710.

In an embodiment, the switch 711 inside the modulator 710 may have a relatively small resistance value (or Ron value) and, accordingly, the loss of power supplied from the battery 210 to the power amplification module 720 via the modulator 710 may be small. For example, a voltage level Vbat of the battery 210 may be at a similar level to a power voltage level Vcc of the power amplification module 720 sensed at a power voltage node of the power amplification module 720.

Table 1 shows the comparison between a battery voltage and a power voltage of a power amplification module according to an embodiment. Referring to Table 1 showing a difference between a voltage level Vbat of the battery 210 and a power voltage level Vcc of the power amplification module 720 for each JIG voltage, it may be determined that a difference value Delta between the voltage level Vbat of the battery 210 and the power voltage level Vcc of the power amplification module 720 is a small level of about 60 mV.

According to an embodiment, the electronic device (e.g., electronic device 101 of FIG. 2, FIG. 4, or FIG. 6) may compensate for the transmission power level for transmitting the Tx signal based on the voltage level information about the battery 210. Accordingly, in the electronic device 101, a process of measuring a power voltage of the power amplification module 720 used to compensate for the transmission power level of the Tx signal may be omitted, and a circuit and component used to measure the power voltage of the power amplification module 720 may also be omitted.

FIG. 8 is a graphical diagram comparing a transmission power compensated based on a battery voltage with a comparison target transmission power by the lapse of time according to an embodiment. FIG. 9 is a graphical diagram comparing a transmission power compensated based on a battery voltage with a comparison target transmission power by the lapse of time according to an embodiment.

Referring to FIGS. 8 and 9, while a transmission event of a Tx signal is maintained, a voltage level of a battery may decrease by the lapse of time. Looking at a section (e.g., a section before two minutes and thirty seconds or a section of battery level of 4.314 V to 4.029 V) before a point of time 930 or 1030 at which the voltage level of the battery switches from a high voltage to a low voltage, it may be determined that a transmission power level 910 or 1010 of a Tx signal compensated based on voltage level information about a battery according to an embodiment and a transmission power level 920 or 1020 of a comparison target Tx signal (e.g., transmission power level of Tx signal not compensated) are at similar levels.

However, looking at a section (e.g., a section after two minutes and thirty seconds or a section of battery level of 3.984 V to 3.307 V) after a point of time 930 or 1030 at which the voltage level of the battery switches from a high voltage to a low voltage, the transmission power level 910 or 1010 of the Tx signal compensated based on the voltage level information about the battery and the transmission power level 920 or 1020 of the comparison target Tx signal may have a significant difference of level magnitude, and it may be determined that the transmission power level 910 or 1010 of the Tx signal compensated based on the voltage level information about the battery is maintained similar to the level when the voltage level of the battery is a high voltage.

Table 2 shows the comparison of a transmission power compensated based on a battery voltage and a comparison target transmission power by the lapse of time and a battery level according to an embodiment. Referring to Table 2, it may be determined that the magnitude of a transmission power level of a comparison target Tx signal (e.g., transmission power level of Tx signal not compensated) decreases to a certain level or more in a section where a voltage level of a battery is a low voltage (e.g., section after two minutes and thirty seconds or section of battery level of 3.897 V to 3.557 V), compared to a section where the voltage level of the battery is a high voltage (e.g., section before two minutes and thirty seconds or section of battery level of 4.278 V to 4.047 V).

According to embodiments of the disclosure, the compensating for the transmission power level of the Tx signal includes determining a compensation value for the compensating for the transmission power level of the Tx signal based on the voltage level information and increasing the transmission power level of the Tx signal by the determined compensation value and outputting the increased transmission power level of the Tx signal.

According to embodiments of the disclosure, a manufacturing cost of an electronic device may be reduced since circuits and components used to compensate for the transmission power level of the Tx signal are omitted.

According to embodiments of the disclosure, the design freedom and component integration for an internal space of the electronic device may be improved since the circuits and components used to compensate for the transmission power level of the Tx signal are omitted.

The effects obtainable from the disclosure are not limited to the effects mentioned above, and other effects not mentioned may be clearly understood by a person having ordinary skill in the art from the embodiments of the disclosure.

The electronic device of various embodiments of the disclosure may include various types of devices. The electronic device may include, for example, a portable communication device (e.g., smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance. The electronic device of an embodiment of the disclosure is not limited to the above-described devices.

Various embodiments of the disclosure and terms used herein are not intended to limit the technical features described in the disclosure to specific embodiments, but should be understood as including various modifications, equivalents, or alternatives of the corresponding embodiment. In relation to the description of the drawings, similar reference numerals may be used for similar or related components. The singular form of a noun corresponding to an item may include a single or plurality of items, unless the relevant context clearly indicates otherwise. In the disclosure, each of phrases such as “A or B”, “at least one of A and B”, “at least one of A or B”, “A, B or C”, “at least one of A, B and C”, and “at least one of A, B, or C” may include any one of items listed together in a corresponding phrase among the phrases, or any possible combination thereof. Terms such as “first”, “second”, “firstly” or “secondly” may be used simply to distinguish a corresponding component from another corresponding component, and do not limit the corresponding components in other respects (e.g., importance or order). When some (e.g., first) component is mentioned to be “coupled” or “connected” to another (e.g., second) component, with or without the term “functionally” or “communicatively”, it means that some component may be connected to another component directly (e.g., wired), wirelessly, or through a third component.

The term “module” used in the disclosure may include a unit implemented in hardware, software, or firmware, and may be used interchangeable with a term such as a logic, a logic block, a component, or a circuit, for example. The module may include an integrated component, or a minimum unit of the component or a part thereof performing one or more functions. For example, according to an embodiment, the module may be implemented in the form of an application-specific integrated circuit (ASIC).

Various embodiments of the disclosure may be implemented as software (e.g., program 140) that includes one or more instructions stored in a storage medium (e.g., internal memory 136 or external memory 138) that is readable by a machine (e.g., electronic device 101). For example, a processor (e.g., processor 120) of the machine (e.g., electronic device 101) may call at least one instruction among the stored one or more instructions from the storage medium, and execute it. This enables the machine to be operated to perform at least one function according to the called at least one instruction. The one or more instructions may include a code provided by a compiler or a code executable by an interpreter. The machine-readable storage medium may be presented in the form of a non-transitory storage medium. Here, ‘non-transitory’ only means that the storage medium is a tangible device and does not include a signal (e.g., electromagnetic wave). This term does not distinguish a case where data is stored semi-permanently in the storage medium and a case where data is stored temporarily.

According to an embodiment, a method of various embodiments of the disclosure may be included and presented in a computer program product. The computer program product may be traded as merchandise between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) through an application store (e.g., Play Store™), directly between two user devices (e.g., smartphones), or online. In the online distribution, at least part of the computer program product may be at least temporarily stored in the machine-readable storage medium such as a memory of a manufacturer's server, an application store's server, or a relay server, or be temporarily provided.

According to various embodiments, each component (e.g., module or program) of the components described above may include a single or plurality of entities. According to various embodiments, one or more components of the corresponding components mentioned above or operations may be omitted, or one or more other components or operations may be added. Alternatively or additionally, a plurality of components (e.g., modules or programs) may be integrated into a single component. In this case, the integrated component may perform one or more functions of each of the plurality of components, identically or similarly to those performed by the corresponding component among the plurality of components prior to the integration. According to various embodiments, operations performed by a module, program, or another component may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order or be omitted, or one or more other operations may be added.
