FIG. 2B is a block diagram (200) of an electronic device (101) for supporting legacy network communication and 5G network communication according to one embodiment.
[0047] Referring to FIG. 2A, the electronic device (101) may include a first communication processor (212), a second communication processor (214), a first radio frequency integrated circuit (RFIC) (222), a second RFIC (224), a third RFIC (226), a fourth RFIC (228), a first radio frequency front end (RFFE) (232), a second RFFE (234), a first antenna module (242), a second antenna module (244), a third antenna module (246), and antennas (248). The electronic device (101) may further include a processor (120) and a memory (130). The second network (199) may include a first cellular network (292) and a second cellular network (294). According to another embodiment, the electronic device (101) may further include at least one of the components described in FIG. 1, and the second network (199) may further include at least one other network. According to one embodiment, the first communication processor (212), the second communication processor (214), the first RFIC (222), the second RFIC (224), the fourth RFIC (228), the first RFFE (232), and the second RFFE (234) may form at least a portion of the wireless communication module (192). According to another embodiment, the fourth RFIC (228) may be omitted or may be included as a part of the third RFIC (226).
[0048] The first communication processor (212) may establish a communication channel in a band to be used for wireless communication with the first cellular network (292), and may support legacy network communication through the established communication channel. In one embodiment, the first cellular network may be a legacy network including a second generation (2G), 3G, 4G, or long term evolution (LTE) network. The second communication processor (214) may establish a communication channel corresponding to a designated band (e.g., about 6 GHz to about 60 GHz) among the bands to be used for wireless communication with the second cellular network (294), and may support 5G network communication through the established communication channel. In one embodiment, the second cellular network (294) may be a 5G network defined by the 3GPP. Additionally, according to one embodiment, the first communication processor (212) or the second communication processor (214) may support establishment of a communication channel corresponding to another designated band (e.g., about 6 GHz or less) among the bands to be used for wireless communication with the second cellular network (294), and 5G network communication through the established communication channel.
[0049] The first communication processor (212) can transmit and receive data with the second communication processor (214). For example, data classified as being transmitted via the second cellular network (294) may be changed to be transmitted via the first cellular network (292). In this case, the first communication processor (212) can receive the transmission data from the second communication processor (214). For example, the first communication processor (212) can transmit and receive data with the second communication processor (214) via the processor-to-processor interface (213). The above interprocessor interface (213) may be implemented as, for example, a universal asynchronous receiver / transmitter (UART) (e.g., HS-UART (high speed-UART) or PCIe (peripheral component interconnect bus express) interface), but there is no limitation on its type. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information using, for example, a shared memory. The first communication processor (212) may transmit and receive various information, such as sensing information, information on output intensity, and resource block (RB) allocation information, with the second communication processor (214).
[0050] Depending on the implementation, the first communication processor (212) may not be directly connected to the second communication processor (214). In this case, the first communication processor (212) may transmit and receive data with the second communication processor (214) through the processor (120) (e.g., application processor). For example, the first communication processor (212) and the second communication processor (214) may transmit and receive data with the processor (120) (e.g., application processor) through an HS-UART interface or a PCIe interface, but there is no limitation on the type of interface. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information with the processor (120) (e.g., application processor) using shared memory.
[0051] According to one embodiment, the first communication processor (212) and the second communication processor (214) may be implemented in a single chip or a single package.

[0052] As described above, at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the integrated communication processor (260) may be implemented as a single chip or a single package. In this case, the single chip or single package may include a memory (or storage means) that stores instructions that cause the performance of at least some of the operations performed according to one embodiment, and a processing circuit (or, the name thereof is not limited, such as an arithmetic circuit) for executing the instructions.

Upon reception, the RF signal may be acquired from the first cellular network (292) (e.g., a legacy network) via an antenna (e.g., the first antenna module (242)) and preprocessed via an RFFE (e.g., the first RFFE (232)). The first RFIC (222) may convert the preprocessed RF signal into a baseband signal so that it may be processed by the first communication processor (212).
[0054] The second RFIC (224) may, upon transmission, convert a baseband signal generated by the first communication processor (212) or the second communication processor (214) into an RF signal (hereinafter, a 5G Sub6 RF signal) of a Sub6 band (e.g., about 6 GHz or less) used in the second cellular network (294) (e.g., a 5G network). Upon reception, the 5G Sub6 RF signal may be acquired from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., the second antenna module (244)) and preprocessed via an RFFE (e.g., the second RFFE (234)). The second RFIC (224) may convert the preprocessed 5G Sub6 RF signal into a baseband signal so that the preprocessed 5G Sub6 RF signal may be processed by a corresponding communication processor among the first communication processor (212) or the second communication processor (214).
[0055] The third RFIC (226) can convert the baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second cellular network (294) (e.g., 5G network). Upon reception, the 5G Above6 RF signal can be acquired from the second cellular network (294) (e.g., 5G network) through an antenna (e.g., antenna (248)) and preprocessed through the third RFFE (236). The third RFIC (226) can convert the preprocessed 5G Above6 RF signal into a baseband signal so that it can be processed by the second communication processor (214). According to one embodiment, the third RFFE (236) can be formed as a part of the third RFIC (226).
[0056] The electronic device (101) may, according to one embodiment, include a fourth RFIC (228) separately from or at least as a part of the third RFIC (226). In this case, the fourth RFIC (228) may convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, referred to as an IF signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and then transmit the IF signal to the third RFIC (226). The third RFIC (226) may convert the IF signal into a 5G Above6 RF signal. Upon reception, the 5G Above6 RF signal may be received from the second cellular network (294) (e.g., a 5G network) via an antenna (e.g., antenna (248)) and converted into an IF signal by the third RFIC (226). The fourth RFIC (228) can convert the IF signal into a baseband signal so that the second communication processor (214) can process it.
[0057] According to one embodiment, the first RFIC (222) and the second RFIC (224) may be implemented as a single chip or at least a portion of a single package. According to one embodiment, when the first RFIC (222) and the second RFIC (224) in FIG. 2A or FIG. 2B are implemented as a single chip or a single package, they may be implemented as an integrated RFIC. In this case, the integrated RFIC may be connected to the first RFFE (232) and the second RFFE (234) to convert a baseband signal into a signal in a band supported by the first RFFE (232) and / or the second RFFE (234), and transmit the converted signal to one of the first RFFE (232) and the second RFFE (234). According to one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as at least a portion of a single chip or a single package. According to an example, at least one antenna module among the first antenna module (242) or the second antenna module (244) can be omitted or combined with another antenna module to process RF signals of a corresponding plurality of bands.
[0058] According to one embodiment, the third RFIC (226) and the antenna (248) may be disposed on the same substrate to form a third antenna module (246). For example, the wireless communication module (192) or the processor (120) may be disposed on the first substrate (e.g., the main PCB). In this case, the third RFIC (226) may be disposed on a portion (e.g., the bottom surface) of a second substrate (e.g., the sub PCB) separate from the first substrate, and the antenna (248) may be disposed on another portion (e.g., the top surface) to form the third antenna module (246). By disposing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line therebetween. This can reduce, for example, the loss (e.g., attenuation) of signals in a high-frequency band (e.g., about 6 GHz to about 60 GHz) used in 5G network communications by the transmission line. Due to this, the electronic device (101) can improve the quality or speed of communication with the second network (294) (e.g., 5G network).
[0059] According to an example, the antenna (248) may be formed as an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC (226) may include a plurality of phase shifters (238) corresponding to the plurality of antenna elements, for example, as part of the third RFFE (236). During transmission, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal to be transmitted to an external source (e.g., a base station of a 5G network) of the electronic device (101) via its corresponding antenna element. During reception, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal received from the external source via its corresponding antenna element to the same or substantially the same phase. This enables transmission or reception via beamforming between the electronic device (101) and the external source.
[0060] The second cellular network (294) (e.g., a 5G network) may operate independently (e.g., Stand-Alone (SA)) or in connection with (e.g., Non-Stand Alone (NSA)) the first cellular network (292) (e.g., a legacy network). For example, the 5G network may only have an access network (e.g., a 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). In this case, the electronic device (101) may access an external network (e.g., the Internet) under the control of the core network (e.g., evolved packed core (EPC)) of the legacy network after accessing the access network of the 5G network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., New Radio (NR) protocol information) may be stored in the memory (230) and accessed by other components (e.g., the processor (120), the first communication processor (212), or the second communication processor (214)).
[0061] FIG. 3 is a block diagram of an electronic device (101) including a power amplifier (380), according to one embodiment. The embodiment of FIG. 3 will be described in more detail with reference to FIGS. 4A, 4B, and 4C. FIGS. 4A, 4B, and 4C are diagrams for explaining an operating mode, according to one embodiment.
[0062] According to one embodiment, the electronic device (101) may include at least one of a power amplifier (380), a modulator (350), or a capacitor (361).
[0063] According to one embodiment, a communication processor (e.g., at least one of the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) can provide a baseband signal for transmission to an RFIC (e.g., at least one of the first RFIC (222), the second RFIC (224), the third RFIC (226), or the fourth RFIC (228)). Alternatively, the communication processor (e.g., at least one of the first communication processor (212), the second communication processor (214), or the unified communication processor (260)) can receive and process a baseband signal for reception from an RFIC (e.g., at least one of the first RFIC (222), the second RFIC (224), the third RFIC (226), or the fourth RFIC (228)).
[0064] According to one embodiment, the processor (120) may execute a calling application. The processor (120) may perform a call based on the calling application. For example, the processor (120) may perform an outgoing call based on a call request from a user (e.g., selection of an icon for a calling request, or a voice command, but is not limited thereto), or may perform an incoming call based on a response request for an incoming call (e.g., selection of an icon for receiving, or a voice command, but is not limited thereto). For example, the processor (120) may perform a call based on an application that provides at least one calling function (e.g., a server-client based application), in addition to a calling application (e.g., an Internet protocol multimedia subsystem (IMS) based application), and those skilled in the art will understand that there is no limitation on the type of the application.
[0065] For example, the processor (120) can output voice for a call through a receiver. The receiver can be a device for outputting voice, and there is no limitation on the receiver. The receiver can be placed so as to be in contact with (or adjacent to) the user's ear, for example, when the user holds the electronic device (101), but there is no limitation on the placement location. For example, the processor (120) can set the receiver as a default output device for a call. For example, the processor (120) can also be set to output voice for a call through the receiver based on the fact that another accessory for voice output, for example, a wired voice output device (for example, but not limited to, a wired earphone) or a wirelessly connected voice output device (for example, but not limited to, a wireless earphone or a wireless speaker), is not operatively connected (for example, but not limited to, a physical connection or the establishment of a wireless communication channel (or connection)). For example, the processor (120) may be set to output voice for a call through the receiver based on not being set to speaker phone mode, but is not limited thereto.
[0066] According to one embodiment, an RFIC (e.g., at least one of the first RFIC (222), the second RFIC (224), the third RFIC (226), or the fourth RFIC (228)) may generate an RF signal (e.g., Sig_in of FIG. 3) corresponding to a baseband signal for transmission and provide the RF signal to a power amplifier (380). The power amplifier (380) may be included in an RFFE (e.g., at least one of the first RFFE (232), the second RFFE (234), or the third RFFE (236)). The RFFE may be configured in the form of a power amplifier module (PAM), a front end module (FEM), a power amplifier module including duplexer (PAMiD), an LNA and PAM with an integrated duplexer or diplexer (LPAMID), or a PA with an integrated low noise amplifier and filter (LPAMIF), and there is no limitation on the form of implementation thereof. Those skilled in the art will understand that the RFFE may be implemented to further include filters and / or antenna switching modules (ASMs). Meanwhile, although FIG. 3 illustrates one power amplifier (380) as being included in the electronic device (101), this is for convenience of explanation, and those skilled in the art will understand that the electronic device (101) may be implemented to include multiple power amplifiers. Meanwhile, an RFFE including an RFIC (e.g., at least one of the first RFIC (222), the second RFIC (224), the third RFIC (226), or the fourth RFIC (228)) and a power amplifier (380) may be referred to as an RF circuit.
[0067] According to one embodiment, the modulator (350) (e.g., at least one of a buck / boost converter, a buck converter, or a boost converter) can provide a supply voltage (Vcc) to the power amplifier (380) using the supplied power. For example, the modulator (350) can provide the supply voltage (Vcc) to the power amplifier (380) using power supplied from a power source (e.g., a battery (189) or an external power source). The power amplifier (380) can amplify an RF signal provided from an RFIC (e.g., at least one of the first RFIC (222), the second RFIC (224), the third RFIC (226), or the fourth RFIC (228)) using the supply voltage (Vcc). The modulator (350) can be configured to operate, for example, in an average power tracking (APT) mode. Alternatively, the modulator (350) may operate in direct mode or ET mode. When operating in ET (envelope tracking) mode, the modulator (350) may be replaced with a linear amplifier. In one example, when operating in direct mode, the supply voltage (Vcc) (401) of the power amplifier (380) may be set to a specified value, as in FIG. 4a. In direct mode, the supply voltage (401) of the specified value may be provided to the power amplifier (380) regardless of the magnitude of the transmission power per signal. In this case, the wasted power consumption may be relatively large. In another example, when operating in APT mode, the supply voltage (Vcc) (402) of the power amplifier (380) may be set (or changed) according to a specified time unit (e.g., slot (or subframe)), as in FIG. 4b.For example, in a subframe (or slot) in which the transmission power of the RF signal is set to 10 to 18 dBm, a supply voltage (Vcc) of 3 V may be supplied to the power amplifier (380), and in a subframe (or slot) in which the transmission power of the RF signal is set to 18 to 24 dBm, a supply voltage (Vcc) of 4 V may be supplied to the power amplifier (380). In another example, when operating in the ET mode, the supply voltage (Vcc) (403) of the power amplifier (380) may be set (or changed) in real time according to the magnitude of the transmission power of the RF signal, as shown in FIG. 4C. When operating in the ET mode, the modulator (350) may track the transmission power of the RF signal in real time and provide a supply voltage corresponding to an envelope of the transmission power to the power amplifier (380). The time interval of setting (or changing) the supply voltage (Vcc) in ET mode may be shorter than the time interval of setting (or changing) the supply voltage (Vcc) in APT mode. The communication processor (e.g., at least one of the first communication processor (212), the second communication processor (214), or the integrated communication processor (260)) (or the modulator) may, for example, set a value based on an I / Q signal of a baseband signal (e.g., ) can be used to determine the size of the supply voltage set in APT mode or ET mode. Although not shown, the electronic device (101) may include at least one of an envelope detector, an envelope shaper, or an amplifier, but is not limited thereto.
[0068] According to one embodiment, the modulator (350) may provide a supply voltage (Vcc) to the power amplifier (380) for transmitting an RF signal according to the APT mode. For example, the modulator (350) may include a switch. Depending on the determined magnitude of the supply voltage (Vcc), the on-duration and off-duration (or the ratio of the on-duration and off-duration) of the switch may be determined, but those skilled in the art will understand that there is no limitation on the method of controlling the magnitude of the supply voltage (Vcc) in the modulator (350). For example, when an RF signal of an ultra high band (UHB) or an operating band with a relatively wide bandwidth (e.g., B48 band, B42 band, N48 band, N41 band, N77 band, N78 band, or N79 band) is transmitted, the APT mode may be utilized, but there is no limitation. The modulator (350) can control the charge and / or discharge amount of the capacitor (361) to supply a determined supply voltage (Vcc).
[0069] FIG. 5A is a block diagram of an electronic device according to one embodiment. FIG. 5B is a block diagram of an electronic device according to one embodiment.
[0070] Referring to FIG. 5A, according to one embodiment, the electronic device (101) may include a first antenna (540), a receiver (550), an oscillator (560), a second antenna (510), a power amplifier (PA) (520), and / or a modulator (530). As described in more detail below with reference to FIG. 5B, the electronic device (101) may utilize the first antenna (540), the receiver (550), and the oscillator (560) for operations related to satellite signals. The electronic device (101) may utilize the second antenna (510), the power amplifier (520) (e.g., the power amplifier (380) of FIG. 3), and the modulator (530) (e.g., the modulator (350) of FIG. 3) for operations related to RF signals.
[0071] According to one embodiment, the first antenna (540) may be an antenna for satellite signals. For example, the electronic device (101) may receive satellite signals (e.g., global navigation satellite system (GNSS) signals) in a band of 1.1 to 1.6 GHz through the first antenna (540). For example, the electronic device (101) may receive L1, L2, or L5 signals by satellite constellation (e.g., global positioning system (GPS), global navigation satellite system (GLONASS), Beidou, Galileo) through the first antenna (540) (e.g., GNSS antenna). For example, satellite signals (e.g., GNSS signals) may include GPS (1575.42 MHz), GLONASS (1602 MHz), Beidou (1561.098 MHz), and Galileo (1575.42 MHz) for the upper L-band (L1), and may include GPS, Galileo (1176.45 MHz), GLONASS, and Beidou (1207.14 MHz) for the lower L-band (L5). Since the magnitude of a satellite signal (e.g., GNSS signal) is very weak, at a maximum level of -130 dBm relative to the ground, low-sensitivity reception performance is very important for an electronic device (101) that receives a satellite signal. As the strength of a satellite signal (e.g., C / N0 (carrier to noise ratio, dB-Hz)) becomes weaker, the accuracy of the positioning operation deteriorates. Therefore, a design is required to prevent degradation of the reception performance of satellite signals due to RF noise. A “positioning operation” may include an operation of receiving a satellite signal, an operation of demodulating a satellite signal, and / or an operation of obtaining satellite information based on a satellite signal.
[0072] According to one embodiment, the receiver (550) may be configured to demodulate a satellite signal. The electronic device (101) may demodulate the satellite signal through the receiver (550). According to one embodiment, the oscillator (560) (e.g., a crystal oscillator including an XO and a TCXO) may be configured to generate a frequency for demodulating the satellite signal. The electronic device (101) may generate a frequency for demodulating the satellite signal through the oscillator (560). The oscillator (560) has a characteristic of being vulnerable to temperature and noise. If the frequency of the oscillator (560) fluctuates due to noise or heat generation, the oscillator (560) may not be able to normally demodulate the satellite signal, which may cause problems such as position deviation.
[0073] According to one embodiment, the second antenna (510) may be an antenna for an RF signal. The electronic device (101) may transmit or receive an RF signal through the second antenna (510). The power amplifier (520) may be configured to amplify the RF signal based on a supply voltage. The electronic device (101) may amplify the RF signal through the power amplifier (520). The modulator (530) may be configured to supply a supply voltage to the power amplifier (520). The electronic device (101) may supply the supply voltage to the power amplifier (520) through the modulator (530). The modulator (530) may include a configuration for an envelope tracking (ET) mode (e.g., boost) and a configuration for an average power tracking (APT) mode (e.g., buck). The electronic device (101) can control the modulator (530) to operate in a first mode (e.g., ET mode) in which the modulator (530) supplies a first type of supply voltage to the power amplifier (520). The first mode can include an ET mode in which the first type of supply voltage is controlled by tracking the transmission power of the RF signal in real time. The electronic device (101) can control the modulator (530) to operate in a second mode (e.g., APT mode) in which the modulator (530) supplies a second type of supply voltage to the power amplifier (520). The second mode can include an APT mode in which the second type of supply voltage is controlled based on an average of the transmission power of the RF signal over a specified time period.
[0074] As described later in Fig. 10, when the frequency band of the RF signal is B13 and B14 of LTE (long term evolution), the second harmonic component overlaps with the GNSS band, which may deteriorate the GNSS performance. If the ET mode is applied during B13 and B14 operation, the noise component may be amplified, which may deteriorate the GNSS performance. In addition, when the ET mode is operated, the surrounding crystal (e.g., the oscillator (560)) may be affected due to the instantaneous heat generation, which may cause an issue (e.g., clock drift, which is a phenomenon in which the frequencies of the oscillator (560) are distorted due to the influence of heat or noise).
[0075] Referring to FIG. 5B, according to one embodiment, the electronic device (101) may include a first antenna (540), a first F / E (551) (e.g., a GNSS front / end), a receiver (550) (e.g., a GNSS receiver), an oscillator (560), a second antenna (510), a second F / E (521) (e.g., an RF front / end), a modulator (530), a transceiver (570) (e.g., an RF integrated circuit (IC)), a power supply, and / or a processor (590) (e.g., the processor (120) of FIG. 1, the first communication processor (212), the second communication processor (214) of FIG. 2A, and / or the integrated communication processor (260) of FIG. 2B).
[0076] In this document, when an electronic device (101) performs a specific operation, it may mean that various hardware included in the electronic device (101), for example, a processor (590) such as an MCU (micro controlling unit), an FPGA (field programmable gate array), an ASIC (application specific integrated circuit), a microprocessor, or an AP (application processor), performs the specific operation. The processor (590) may include a processing circuit. When the electronic device (101) performs a specific operation, it may mean that the processor (590) controls other hardware to perform the specific operation. The electronic device (101) performing a specific operation may mean that at least one instruction for performing the specific operation stored in a storage circuit (e.g., memory (130)) of the electronic device (101) is executed, thereby causing the processor (590) or other hardware to perform the specific operation. At least one instruction stored in the memory (130) of the electronic device (101), when individually or collectively executed by at least one processor (590), may cause the electronic device (101) to perform at least one operation.
[0077] In one embodiment, the first F / E (551) may include an amplifier for amplifying a received satellite signal and a filter for filtering frequency components. The first F / E (551) may receive power from a power supply (580). The electronic device (101) may provide an enable signal from a receiver (550) (e.g., a GNSS receiver) to the first F / E (551).
[0078] According to one embodiment, the electronic device (101) can determine a pseudo range between a satellite and the electronic device (101) through a receiver (550) (e.g., a GNSS receiver). The electronic device (101) can provide navigation data (e.g., Ephemeris, Almanac) from the receiver (550) to the processor (590). The electronic device (101) can measure the reception sensitivity of a satellite signal (e.g., a GNSS signal) through a carrier to noise ratio (C / N0).
[0079] According to one embodiment, the second F / E (521) may include a power amplifier (520) for amplifying an RF signal, a filter, a switch, and / or a matching circuit. Although FIG. 5B illustrates that the RF front / end, the RF antenna, and the modulator of the electronic device (101) are each one (e.g., the second F / E (521), the second antenna (510), and the modulator (530)), this is for convenience of explanation, and the electronic device (101) may include an antenna (e.g., the second antenna (510)), an F / E (e.g., the second F / E (521)), and a modulator (e.g., the modulator (530)) for each frequency (e.g., mid & high band and low band).
[0080] According to one embodiment, a transceiver (570) (e.g., an RF integrated circuit (IC)) may provide a fundamental signal to a power amplifier (520). The power amplifier (520) may amplify the fundamental signal provided from the transceiver (570) based on a supply voltage provided to the modulator (530). The amplified signal may be transmitted externally via a second antenna (510). The transceiver (570) may include a digital to analog converter (DAC) configured to modulate a digital signal into an analog signal and an analog to digital converter (ADC) configured to demodulate a received analog signal into a digital signal. The electronic device (101) may modulate and demodulate a signal via the transceiver (570). The electronic device (101) can control the operation of the F / E (e.g., the second F / E (521)) through the transceiver (570) according to a communication standard (e.g., a communication standard including 5G, 4G, and 3G communication standards). The electronic device (101) can provide RF-related information of the electronic device (101) from the transceiver (570) to the processor (590). The electronic device (101) can provide GNSS-related information of the electronic device (101) from the processor (590) to the transceiver (570).
[0081] According to one embodiment, the electronic device (101) may provide power to components of the electronic device (101) (e.g., a receiver (550), a transceiver (570), a processor (590), a first F / E (551), a second F / E (521), a modulator (530), and / or an oscillator (560)) via a power supply (580). The processor (590) may control the power supply (580).
[0082] According to one embodiment, the processor (590) of the electronic device (101) may generate data (e.g., signals) for communication. The processor (590) of the electronic device (101) may control the receiver (550) and the transceiver (570). The processor (590) of the electronic device (101) may detect a positioning operation (e.g., GNSS operation). The processor (590) of the electronic device (101) may provide information about the positioning operation (e.g., GNSS operation) to the transceiver (570). The transceiver (570) may change the mode (e.g., ET mode or APT mode) of the modulator (530) based on the information about the positioning operation (e.g., GNSS operation) provided from the processor (590). A signal for changing the mode (e.g., ET mode or APT mode) of the modulator (530) may be provided directly from the processor (590) to the modulator (530). A signal for changing the mode (e.g., ET mode or APT mode) of the modulator (530) may be provided directly from the receiver (550) to the modulator (530).
[0083] According to one embodiment, the processor (590) of the electronic device (101) may detect a degradation in the performance of a positioning operation (e.g., a GNSS operation). If the position of the electronic device (101) due to the positioning operation after the operation of the ET mode during RF communication deviates by a set distance (e.g., 30 m) or more compared to the existing one or a signal loss phenomenon occurs, the electronic device (101) (e.g., the processor (590)) may provide information to the transceiver (570) so that the modulator (530) operates in the APT mode. The electronic device (101) (e.g., the processor (590)) may provide information to the transceiver (570) so as to reduce the maximum transmission power of the power amplifier (520) based on detecting a degradation in the performance of the positioning operation (e.g., a GNSS operation). A signal for reducing the maximum transmission power of the power amplifier (520) may also be directly provided from the processor (590) to the power amplifier (520). A signal for reducing the maximum transmission power of the power amplifier (520) may be directly provided from the receiver (550) to the power amplifier (520). The electronic device (101) (e.g., processor (590)) may avoid using a resource block (RB) that affects the positioning operation during B13 or B14 operation of LTE. The electronic device (101) (e.g., processor (590)) may also adjust the level to lower the transmission power of the RF signal during envelope tracking by determining the current electric field level based on the satellite information confirmed through the receiver (550).
[0084] The operations of the electronic device (101) can be described in detail with reference to the embodiments described above (e.g., the embodiments of FIGS. 1 to 5B) and the embodiments described below (e.g., the embodiments of FIGS. 6 to 12). Although each embodiment is disclosed in a separate drawing and a separate paragraph, this is merely for convenience of explanation, and at least some of the embodiments described above and at least some of the embodiments described below can be applied together. At least some of the embodiments described above and at least some of the embodiments described below may be omitted.
[0085] FIG. 6 is a flowchart of a method of operating an electronic device according to one embodiment.
[0086] At least some of the operations of FIG. 6 may be omitted. The order of the operations of FIG. 6 may be changed. Operations other than the operations of FIG. 6 may be performed before, during, or after the operations of FIG. 6.
[0087] Referring to FIG. 6, in operation 601, according to one embodiment, the electronic device (101) may control the modulator (530) to operate in a first mode in which the modulator (530) supplies a first type of supply voltage to the power amplifier (520). For example, the first mode may include an envelope tracking (ET) mode in which the first type of supply voltage is controlled by tracking the transmission power of an RF signal in real time.
[0088] In operation 603, according to one embodiment, the electronic device (101) may determine whether a positioning operation is performed while the modulator (530) operates in the first mode. The “positioning operation” may include an operation of receiving a satellite signal, an operation of demodulating a satellite signal, and / or an operation of acquiring satellite information based on a satellite signal.
[0089] In operation 605, according to one embodiment, the electronic device (101) may maintain the first mode (e.g., ET mode) of the modulator (530) based on the location positioning operation performed via the receiver (550) being not confirmed.
[0090] In operation 607, according to one embodiment, the electronic device (101) can control the modulator (530) to operate in a second mode in which the modulator (530) supplies a second type of supply voltage to the power amplifier (520) based on the confirmation of a positioning operation while the modulator (530) operates in the first mode. For example, the second mode can include an average power tracking (APT) mode in which the second type of supply voltage is controlled based on an average of the transmit power of the RF signal over a specified period of time.

[0142] In operation 1211, according to one embodiment, the electronic device (101) may control the modulator (530) to operate in a second mode (e.g., APT mode) based on determining that the electronic device (101) is located at a learned location (e.g., the first location or the second location of operation 1203) while the modulator (530) operates in a first mode (e.g., ET mode).
[0143] Electronic devices (101) can provide location-based services and applications. For example, there is a navigation application that provides directions to a destination while driving.

[0144] A user carrying an electronic device (101) may use a positioning operation (e.g., GNSS) when collecting exercise information during running, cycling, or mountain trekking. If an incorrect location is recorded due to the use of ET mode, errors may occur in calculating the distance, time, or calories exercised. In this case, the embodiments of FIGS. 1 to 12 may be utilized.
[0145] Furthermore, in location-based virtual reality games, users can actually move based on the location displayed in the game. Accurate location information is essential, as any deviation from the intended location can lead to problems not only in game play but also in danger of falls or car accidents. In this case, the embodiments of FIGS. 1 through 12 can be utilized.
[0146] In situations where real-time map and information downloading is required, the embodiments of FIGS. 1 to 12 can be utilized so that GNSS positioning is not affected by noise and heat generation issues due to ET mode, since RF data communication is performed simultaneously with positioning operation.
[0147] In an emergency, when a user calls a police station or a fire station through an electronic device (101) and transmits the user's location information, data communication through RF transmission and reception and a process of calculating and transmitting the exact location from a GNSS receiver (e.g., 550) can occur simultaneously. In this case, when RF communication and GNSS positioning are performed simultaneously, if the ET mode of the modulator (530) operates, it may lead to inaccurate positioning. In an emergency, when human lives are at stake, if a position error occurs, it may lead to a big problem, so the embodiments of FIGS. 1 to 12 can be utilized to prevent the GNSS performance from deteriorating.
