[0049] In one embodiment, a processor (e.g., processor (110) of FIG. 1) can perform a back-off operation based on the reflection coefficient of the antenna.

[0050] In one embodiment, a processor (e.g., processor (110) of FIG. 1) can perform a back-off operation based on the amplitude component and phase component of the reflection coefficient.

[0051] In one embodiment, a processor (e.g., processor (110) of FIG. 1) may back off the transmission power (or MTPL) based on the reflection coefficient when it is expected that the SAR expected by the transmission power will exceed a threshold value.

[0052] In one embodiment, the transceiver (261) can convert a signal input from the processor (110) into an RF signal (e.g., a transmission signal) and output it to a power amplifier (263). For example, the signal input from the processor (110) may be a transmission signal to be transmitted to an external electronic device. Additionally, the transceiver (261) can convert an RF signal (e.g., a reception signal) received from a low-noise amplifier (265) into digital data that can be processed by the processor (110) and transmit it to the processor (110).

[0053] In one embodiment, a signal output from a transceiver (261) may be input to a power amplifier (263), and the power amplifier (263) may amplify the signal input from the transceiver (261) based on a set amplification gain and then output the amplified signal to a duplexer (267). The signal output from the power amplifier (263) may be input to a duplexer (267), and the duplexer (267) may perform a duplex operation on the signal input from the power amplifier (263) and output it to an adaptive switch module (269).

[0055] In one embodiment, a signal output from an adaptive switch module (269) can be input to a coupler (271), and the coupler (271) can perform a coupling operation on the signal output from the adaptive switch module (269) and output it to an antenna tuner (274) through an RF switch (273).

[0056] In one embodiment, the antenna tuner (274) can perform a tuning operation based on a set value (e.g., a tuning code), and the signal input through the RF switch (273) can be grounded through the ground circuit (275) and then output through the antenna (240).

[0057] In one embodiment, the antenna tuner (274) can adjust the impedance of the antenna (240) to be close to at least one reference impedance based on a set value (e.g., tuning code) set by the processor.

[0058] In one embodiment, the antenna tuner (274) may include at least one of a switch, a resistor (register), an inductor, or a capacitor. For example, the antenna tuner (274) may adjust the electrical length (e.g., capacitor, inductor, or resistor) between the antenna (240) and the transceiver (261) based on a tuning code to adjust the reflection caused by the impedance difference between the antenna (240) and the transceiver (261).

[0059] In one embodiment, the ground circuit (275) can adjust the resonant frequency by adjusting the electrical length between the antenna (240) and ground based on a set value (e.g., ground code) set by the processor. By adjusting the resonant frequency, the ground circuit (275) can reduce reflections caused by the impedance difference between the antenna (240) and the transceiver (261).

[0060] In one embodiment, the processor (110) can control the ground circuit (275) based on the communication frequency used in the electronic device (100). For example, the processor (110) can control the length of the antenna (240) by controlling the ground controller (XGND).

[0061] In one embodiment, the processor (110) can control the antenna tuner (274) to match the impedance of the antenna (240) based on the communication frequency used in the electronic device (100).

[0062] In one embodiment, the processor (100) can receive a feedback signal (e.g., a forward coupling signal or a reverse coupling signal) from the coupler (271) to determine the current antenna load (or antenna impedance).

[0063] In one embodiment, the coupler (271) is coupled to a signal line between a power amplifier (263) and an antenna tuner (274) to output a feedback signal corresponding to a communication signal and transmit it to a processor (110).

[0064] In one embodiment, the processor (100) can determine the reflection coefficient (Γi) directed toward the antenna (240) from the input of the antenna tuner (274) through the ratio of the reverse and forward voltages of the feedback signal. Hereinafter, for convenience of explanation, the reflection coefficient (Γi) directed toward the antenna (240) from the input of the antenna tuner (274) (or antenna tuning circuit (230)) will be referred to as the "input reflection coefficient."

[0065] In one embodiment, to determine the reflection coefficient (ΓL) directed toward the antenna (240) from the output of the antenna tuner (274), a value in which the reflection coefficient (ΓL) is matched to an optimal impedance (e.g., about 50 Ω) may be set as a reference reflection coefficient, an antenna ground code corresponding to the reference reflection coefficient may be set as a reference ground code, and a tuning code of the antenna tuner (274) that is set to minimize the input reflection coefficient (Γi) of the antenna tuner (274) may be set as a reference tuning code. Hereinafter, for convenience of explanation, the reflection coefficient (ΓL) directed toward the antenna (240) from the output of the antenna tuner (274) will be referred to as the "output reflection coefficient."

[0066] In one embodiment, the in-phase component (hereinafter I component) and quadrature component (hereinafter Q component) of the input reflection coefficient (Γi) can be mapped to and stored in a plurality of indices, and for each index, the output reflection coefficient (ΓL) is checked by applying the mapped input reflection coefficient (Γi) and the s parameter of the antenna tuner (274), and the value with the maximum gain is checked as an optimal tuning code, and this value can be stored in memory (120) as a lookup table.

[0067] In one embodiment, the processor (110) can control a tuning code for the antenna tuner (274), and the impedance corresponding to the tuning code can be changed to an optimal impedance for communication (e.g., about 50Ω). For example, an impedance of 50Ω may be an impedance in which both the I component and the Q component of the reflection coefficient are zero (e.g., the origin of the IQ coordinate corresponding to the reflection coefficient).

[0068] In one embodiment, the processor (110) selects from a lookup table the index closest to the output reflection coefficient (ΓL) derived from the input reflection coefficient (Γi) measured through the coupler (271), and applies the ground code of the selected index so that the output reflection coefficient (ΓL) can be changed to correspond to an optimal impedance (e.g., about 50 Ω).

[0069] In one embodiment, the processor (110) can control the ground circuit (275) based on the communication frequency used in the electronic device (100). For example, the processor (110) can control the ground circuit (275) to adjust the electrical length of the antenna (240). The processor (110) can set a tuning code as a reference tuning code and measure the input reflection coefficient (Γi) by the ground circuit (275) and set a value where the measured input reflection coefficient (Γi) is close to a reference index (e.g., index [0]) or an optimal impedance (e.g., about 50Ω) as the reference ground code.

[0070] In one embodiment, the processor (110) can apply a reference tuning code to a reference ground code in a specific usage situation (e.g., inserting an earphone jack, holding in a hand, or mounting in a case), determine the index closest to the measured input reflection coefficient (Γi), identify the optimal ground code for each specific usage situation, and store it in a lookup table corresponding to the index. For example, in a specific usage situation, the tuning code can be set as the reference tuning code, and the input reflection coefficient (Γi) can be measured while varying the ground code, and the value where the input reflection coefficient (Γi) is close to the reference index or the optimal impedance can be identified as the optimal ground code.

[0071] In one embodiment, the I and Q components of the input reflection coefficient (Γi) can be represented as coordinates on an IQ coordinate plane. Additionally, based on the IQ coordinate plane, the amplitude and phase components of the input reflection coefficient (Γi) can be represented as I and Q values, respectively. The electronic device (100) can store the coordinate information, amplitude, and phase information of the I and Q components of the input reflection coefficient (Γi), expressed based on the IQ coordinate plane, in a memory (120).

[0072] In one embodiment, the I and Q components of the input reflection coefficient (Γi) may have their phases changed on the IQ coordinate plane according to the temperature of the electronic device (100) or the temperature of the communication circuit (160) (e.g., PAMiD). If the usage state of the antenna (240) (e.g., insertion into an earphone jack, holding in a hand, or mounting in a case) is determined based on the reflection coefficient (e.g., input reflection coefficient (Γi)) whose phase is changed by temperature, the electronic device (100) may incorrectly determine the usage state of the antenna (240). By compensating for the reflection coefficient (e.g., input reflection coefficient (Γi)) whose phase is changed by temperature according to one embodiment of the present disclosure, the electronic device (100) can accurately determine the usage state of the antenna (240).

[0079] In FIG. 3c, the x-axis represents the temperature change of the electronic device (100), the y-axis represents the phase change of the reflection coefficient (e.g., input reflection coefficient (Γi)), and points on the temperature-phase coordinate plane represent the phase change according to temperature.

[0080] Referring to FIG. 3c, it can be seen that the phase of the temperature of the electronic device (100) and the reflection coefficient (e.g., input reflection coefficient (Γi)) has a linear characteristic.

[0081] Referring to FIGS. 3a, 3b and 3c, due to the linear correlation between the temperature of the electronic device (100) and the phase of the reflection coefficient (e.g., input reflection coefficient (Γi)), the electronic device (100) can determine the I component and Q component of the temperature of the electronic device (100) and the reflection coefficient (e.g., input reflection coefficient (Γi)).

[0082] In one embodiment, the electronic device (100) can determine, under the control of the processor (110), the phase change of the reflection coefficient (e.g., input reflection coefficient (Γi)) according to the temperature change of the electronic device (100) through calculation based on the temperature of the electronic device (100) and the I component and Q component.

[0116] For example, the IQ plane may include a coordinate plane generated based on the I component axis and / or the Q component axis.

The electronic device (100), under the control of the processor (110), can identify a circle (621) passing through the first IQ point (601) and the second IQ point (603) based on the origin (620) of the circle.

For example, according to one embodiment, a module may be implemented in the form of an application-specific integrated circuit (ASIC).

[0169] One embodiment of the present document may be implemented as software (e.g., a program) comprising one or more instructions stored in a storage medium (e.g., internal memory) or external memory that is readable by a machine (e.g., an electronic device (100)). For example, a processor (e.g., a processor (120)) of the machine (e.g., an electronic device (100)) may call at least one of the one or more instructions stored in the storage medium and execute it. This enables the machine to be operated to perform at least one function according to the at least one called instruction. The one or more instructions may include code generated by a compiler or code that can be executed by an interpreter. The storage medium readable by the machine may be provided in the form of a non-transitory storage medium. Here, 'non-temporary' simply means that the storage medium is a tangible device and does not contain a signal (e.g., electromagnetic waves), and the term does not distinguish between cases where data is stored semi-permanently and cases where it is stored temporarily.

[0170] According to one embodiment, the method according to one embodiment disclosed herein may be provided by being included in a computer program product. The computer program product may be traded between a seller and a buyer as a product. The computer program product may be distributed in the form of a device-readable storage medium (e.g., compact disc read-only memory (CD-ROM)) or an application store (e.g., Play Store). TM It can be distributed online (e.g., downloaded or uploaded) through ) or directly between two user devices (e.g., smartphones). In the case of online distribution, at least a portion of the computer program product may be temporarily stored or temporarily created on a device-readable storage medium, such as the memory of a manufacturer's server, an application store's server, or a relay server.

[0171] According to one embodiment, each component (e.g., module or program) of the components described above may include a singular or multiple entities, and some of the multiple entities may be separated and placed in other components. According to one embodiment, one or more of the components or operations among the aforementioned components may be omitted, or one or more other components or operations may be added. Generally or additionally, multiple components (e.g., module or program) may be integrated into a single component. In this case, the integrated component may perform one or more functions of each of the multiple components in the same or similar manner as those performed by the corresponding component among the multiple components prior to integration. According to one embodiment, operations performed by the module, program, or other components may be executed sequentially, in parallel, iteratively, or heuristically, or one or more of the operations may be executed in a different order, omitted, or one or more other operations may be added.
