For example, if the electronic device (101) includes a main processor (121) and an auxiliary processor (123), the auxiliary processor (123) may be configured to use lower power than the main processor (121) or to be specialized for a designated function. The auxiliary processor (123) may be implemented separately from the main processor (121) or as part thereof.

[0020] The auxiliary processor (123) may control at least some of the functions or states associated with at least one component of the electronic device (101) (e.g., display module (160), sensor module (176), or communication module (190)) on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. According to one embodiment, the auxiliary processor (123) (e.g., image signal processor or communication processor) may be implemented as part of another functionally related component (e.g., camera module (180) or communication module (190)). According to one embodiment, the auxiliary processor (123) (e.g., neural network processing unit) may include a hardware structure specialized for processing an artificial intelligence model. The artificial intelligence model may be generated through machine learning. Such learning may be performed, for example, on the electronic device (101) itself where the artificial intelligence model is executed, or through a separate server (e.g., server (108)). The learning algorithm may include, for example, supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but is not limited to the examples described above.

The display module (160) may include, for example, a display, a holographic device, or a projector and a control circuit for controlling said device. According to one embodiment, the display module (160) may include a touch sensor configured to detect a touch, or a pressure sensor configured to measure the intensity of the force generated by said touch.

[0028] The audio module (170) can convert sound into an electrical signal or, conversely, convert an electrical signal into sound. According to one embodiment, the audio module (170) can acquire sound through the input module (150) or output sound through the sound output module (155) or an external electronic device (e.g., electronic device (102)) (e.g., speaker or headphones) connected directly or wirelessly to the electronic device (101).

[0029] The sensor module (176) can detect the operating state of the electronic device (101) (e.g., power or temperature) or the external environmental state (e.g., user state) and generate an electrical signal or data value corresponding to the detected state.

[0030] The interface (177) may support one or more specified protocols that can be used for the electronic device (101) to be connected directly or wirelessly to an external electronic device (e.g., electronic device (102)). According to one embodiment, the interface (177) may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface.

[0031] The connection terminal (178) may include a connector through which the electronic device (101) can be physically connected to an external electronic device (e.g., electronic device (102)). According to one embodiment, the connection terminal (178) may include, for example, an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

[0032] The haptic module (179) can convert an electrical signal into a mechanical stimulus (e.g., vibration or movement) or an electrical stimulus that the user can perceive through tactile or kinesthetic senses. According to one embodiment, the haptic module (179) may include, for example, a motor, a piezoelectric element, or an electric stimulation device.

[0033] The camera module (180) can capture still images and video. According to one embodiment, the camera module (180) may include one or more lenses, image sensors, image signal processors, or flashes.

[0034] The power management module (188) can manage power supplied to the electronic device (101). According to one embodiment, the power management module (188) can be implemented, for example, as at least part of a power management integrated circuit (PMIC).

[0035] The battery (189) can supply power to at least one component of the electronic device (101). According to one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0036] The communication module (190) can support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between an electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may include one or more communication processors that operate independently of the processor (120) (e.g., application processor) and support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., cellular communication module, short-range wireless communication module, or GNSS (global navigation satellite system) communication module) or a wired communication module (194) (e.g., LAN (local area network) communication module, or power line communication module). The corresponding communication module among these communication modules can communicate with an external electronic device (104) through a first network (198) (e.g., a short-range communication network such as Bluetooth, WiFi (wireless fidelity) direct, or IrDA (infrared data association)) or a second network (199) (e.g., a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can identify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) using subscriber information (e.g., International Mobile Subscriber Identifier (IMSI)) stored in the subscriber identification module (196).

[0037] The wireless communication module (192) can support 5G networks and next-generation communication technologies following 4G networks, for example, new radio access technology. NR access technology can support high-speed transmission of high-capacity data (enhanced mobile broadband (eMBB)), minimization of terminal power and connection of multiple terminals (massive machine type communications (mMTC)), or high reliability and low latency (ultra-reliable and low-latency communications (URLLC)). The wireless communication module (192) can support a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate, for example. The wireless communication module (192) can support various technologies for securing performance in the high-frequency band, such as beamforming, massive MIMO (multiple-input and multiple-output), full-dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large-scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), external electronic device (e.g., electronic device (104)), or network system (e.g., second network (199)). According to one embodiment, the wireless communication module (192) can support a Peak data rate (e.g., 20 Gbps or more) for realizing eMBB, loss coverage (e.g., 164 dB or less) for realizing mMTC, or U-plane latency (e.g., downlink (DL) and uplink (UL) each 0.5 ms or less, or round trip 1 ms or less) for realizing URLLC.

[0038] An antenna module (197) can transmit a signal or power to or from an external source (e.g., an external electronic device). According to one embodiment, the antenna module (197) may include an antenna comprising a radiator made of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). According to one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as a first network (198) or a second network (199), may be selected from the plurality of antennas, for example, by a communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device through the selected at least one antenna. According to some embodiments, in addition to the radiator, other components (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as part of the antenna module (197).

[0039] According to various embodiments, the antenna module (197) may form a mmWave antenna module. According to one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent to a first surface (e.g., bottom surface) of the printed circuit board and capable of supporting a specified high frequency band (e.g., mmWave band), and a plurality of antennas (e.g., array antennas) disposed on or adjacent to a second surface (e.g., top surface or side surface) of the printed circuit board and capable of transmitting or receiving a signal of the specified high frequency band.

[0040] At least some of the above components can be connected to each other via a communication method between peripheral devices (e.g., bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)) and exchange signals (e.g., commands or data) with each other.

[0041] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) through a server (108) connected to a second network (199). Each of the external electronic devices (102, or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations performed on the electronic device (101) may be performed on one or more of the external electronic devices (102, 104, or 108). For example, if the electronic device (101) needs to perform a function or service automatically or in response to a request from a user or another device, the electronic device (101) may request one or more external electronic devices to perform at least part of the function or service instead of performing the function or service itself or additionally. One or more external electronic devices that receive the above request may execute at least part of the requested function or service, or additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may provide the result as is or additionally processed as at least part of the response to the request. For this purpose, for example, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used. The electronic device (101) may provide ultra-low latency services using, for example, distributed computing or mobile edge computing. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server using machine learning and / or neural networks. According to one embodiment, the external electronic device (104) or the server (108) may be included within the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0042] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) can perform satellite communication and / or global navigation satellite system (GNSS) communication. For example, the electronic device may include a component (e.g., RFFE circuit) for satellite communication and / or GNSS communication. Satellite communication may be performed in a first frequency band. GNSS communication may be performed in a second frequency band. While the electronic device performs satellite communication through the first frequency band, it may perform GNSS communication through the second frequency band. In the specification below, an electronic device for performing satellite communication and GNSS communication will be described.

[0043] FIG. 2a illustrates an example of an electronic device according to one embodiment.

[0044] FIG. 2b illustrates examples of a first frequency band and a second frequency band according to one embodiment.

[0045] Referring to FIGS. 2a and 2b, the electronic device (200) may include an RFFE module (210), a switch circuit (222), an extraction circuitry (221), a filter (223), a filter (224), and / or an antenna (230). The components shown in FIG. 2a may be used to perform satellite communication and GNSS communication. Although not shown, the electronic device (200) may further include a processor (e.g., processor (410) of FIG. 4) and / or an RF transceiver (e.g., RF transceiver (420) of FIG. 4). The switch circuitry (222) may be controlled by at least one of the processor and / or RF transceiver.

[0046] Referring to FIG. 2b, satellite communication may be performed within a first frequency band (280) that may include multiple frequency bands (e.g., separated into frequency ranges). GNSS communication may be performed within a second frequency band (290). For example, the first frequency band (280) may include a receiving frequency range (281) and a transmitting frequency range (282). The receiving frequency range (281) may be set from a frequency (283) (e.g., lower boundary) to a frequency (284) (e.g., upper boundary). The transmitting frequency range (282) may be set from a frequency (285) (e.g., lower boundary) to a frequency (286) (e.g., upper boundary). For example, the receiving frequency range (281) may be set from 1525 [MHz] to 1559 [MHz]. The transmission frequency range (282) can be set from 1626.5 [MHz] to 1660.5 [MHz]. For example, the first frequency band (280) can be referred to as the 3GPP standard B255 or n255 band. The reception frequency range (281) of the first frequency band (280) can be referred to as the DL (downlink) band. The transmission frequency range (282) of the first frequency band (280) can be referred to as the UL (uplink) band.

[0047] For example, the second frequency band (290) can be set from frequency (291) (e.g., lower limit) to frequency (292) (e.g., upper limit). As an example, the second frequency band (290) can be set from 1565.42 [MHz] to 1585.42 [MHz]. The second frequency band (290) can be referred to as the L1 band. As an example, the second frequency band (290) can be set from 1560.42 [MHz] to 1590.42 [MHz]. The second frequency band (290) can be referred to as the E1 band.

[0048] Referring again to FIG. 2a, the RFFE module (210) may include a plurality of ports. For example, the RFFE module (210) may include port (211), port (212), port (213), port (214), port (215), port (216), and port (217). For example, port (216) may be used to output a signal (e.g., SRS (sounding reference signal)) of a band for a communication network (e.g., N41 band). For example, port (216) may be used for a different frequency band distinct from the aforementioned frequency bands (e.g., first frequency band (280), second frequency band (290)).

[0049] For example, the port (211) can be used to output a midband (MB) signal. The port (211) can be connected to a switch circuit (222). The signal of the MB can be provided to the switch circuit (222). The electronic device (200) can control the path of the MB signal by controlling the switch circuit (222).

[0050] For example, an electronic device (200) may provide a path for transmitting a signal to a filter (223) configured to pass an n256 band signal using a switch circuit (222). Although not shown in FIG. 2b, the n256 band may include a transmission frequency band from 1980 [MHz] to 2010 [MHz] and a reception frequency band from 2170 [MHz] to 2200 [MHz]. An n256 band signal may be input to a port (214). An n256 band signal may be transmitted from the port (217) to an antenna (230) through an extraction circuit (221). An n256 band signal may be radiated through the antenna (230).

[0051] For example, an electronic device (200) may use a switch circuit (222) to provide a path for transmitting a signal to a filter (224) configured to pass a signal of a first frequency band (280) (e.g., n255 band). A signal of the transmission frequency range (282) of the first frequency band (280) may be input to a port (215). A signal of the transmission frequency range (282) may be transmitted from the port (217) to an antenna (230) through an extraction circuit (221). A signal of the transmission frequency range (282) may be radiated through the antenna (230).

[0052] For example, the extraction circuit (221) may be configured to pass a signal provided to the antenna (230). The extraction circuit (221) may be configured to acquire a signal of the second frequency band (290) among the signal(s) received from the antenna (230) (e.g., a signal received from the antenna (230) and input to the extraction circuit (221)). Although not illustrated, the signal of the second frequency band (290) may be provided to a circuit for signal processing regarding GNSS communication. The extraction circuit (221) may be referred to as a surface acoustic wave (SAW) filter.

[0053] According to one embodiment, a signal of the receiving frequency range (281) of the first frequency band (280) received through the antenna (230) may pass through the extraction circuit (221). In the extraction circuit (221), since a portion of the receiving frequency range (281) is extracted, the signal of the receiving frequency range (281) (or at least a portion of the signal of the receiving frequency range (281)) may not be input to the port (217). Therefore, the signal of the receiving frequency range (281) may not be provided to the filter (224) through the port (215).

[0054] According to one embodiment, a signal in the receiving frequency range of the n256 band received through the antenna (230) may pass through an extraction circuit (221). The signal in the receiving frequency range of the n256 band may be input to a port (217). The signal in the receiving frequency range of the n256 band may be provided to a filter (223) through a port (214). The signal in the receiving frequency range of the n256 band that has passed through the filter (223) may be provided to a port (213). Although not illustrated, the signal in the receiving frequency range of the n256 band input to the port (213) may be processed by an RFFE module (210), an RF transceiver, and / or a processor.

[0055] Referring to FIG. 2b, the passband (or extraction band) of the extraction circuit (221) may correspond to a frequency band (270). The frequency band (270) may be set from frequency (271) to frequency (272). For example, a signal of the second frequency band (290) that has passed through the extraction circuit (221) may be provided to a circuit for signal processing regarding GNSS communication. If the signal of the second frequency band (290) contains noise of a reference size, the electronic device (200) may not be able to demodulate the signal of the second frequency band (290).

[0056] According to one embodiment, the gap between frequency (284) and frequency (291) may be small for filtering. For example, the gap may not be sufficiently large, and consequently, the passband may include frequency (284). That is, frequency (271) may be smaller than frequency (284). The passband (or extraction band) of the extraction circuit (221) may overlap with the receiving frequency range (281) of the first frequency band (280). Thus, the electronic device (200) may not receive a signal through the first frequency band (280) while receiving a signal through the second frequency band (290). For example, the electronic device (200) may not be able to demodulate the received signal of the first frequency band (280) while receiving a signal through the second frequency band (290).

[0057] For example, the gap between frequency (292) and frequency (285) may be small enough to filter. Frequency (272) may be larger than frequency (285). For example, the gap may not be sufficiently large, and consequently, the passband may include frequency (285). That is, the passband (or extraction band) of the extraction circuit (221) may overlap with the transmission frequency range (282) of the first frequency band (280). Thus, while the electronic device (200) transmits a signal through the first frequency band (280) using the antenna (230), it may not receive a signal through the second frequency band (290) using the antenna (230). For example, while the electronic device (500) transmits a signal through the first frequency band (280), it may not be able to demodulate the received signal of the second frequency band (290). It is possible to use a high-quality filter, that is, a more expensive filter, to ensure that the passband (or extraction band) does not overlap with the transmission frequency range (282). However, it is also impossible to filter the reception frequency range (281) in a similar manner. (For example, a filter having a passband that does not overlap the transmission frequency range (282) and the reception frequency range (281) cannot be used.) Therefore, even if a more expensive / high-quality filter is used, the problem remains that the electronic device (200) may not be able to receive a signal through the first frequency band (280) while receiving a signal through the second frequency band (290).

[0058] As described above, the electronic device (200) may not be able to perform satellite communication and GNSS communication simultaneously through the antenna (230). In the specification below, specific examples of electronic devices for performing satellite communication and GNSS communication simultaneously will be described.

[0059] FIG. 3a illustrates an example of an electronic device according to one embodiment.

[0060] FIG. 3b illustrates an example of an electronic device according to one embodiment.

[0061] Referring to FIGS. 3a and 3b, the electronic device (300) can perform satellite communication and GNSS communication simultaneously. For example, the electronic device (300) can receive a signal in the second frequency band (290) while transmitting a signal in the first frequency band (280). The electronic device (300) can receive a signal in the first frequency band (280) while receiving a signal in the second frequency band (290).

[0062] According to one embodiment, a transmission signal of the first frequency band (280) may be provided from the port (211) to the switch circuit (326). A transmission signal of the first frequency band (280) may be provided from the switch circuit (326) to the filter (323). The filter (323) may be configured to pass a signal of the transmission frequency range (282) of the first frequency band (280). A transmission signal of the first frequency band (280) may be provided from the filter (323) to the port (215) of the RFFE module (210). A transmission signal of the first frequency band (280) may be provided from the port (215) of the RFFE module (210) to the port (217) of the RFFE module (210). A transmission signal of the first frequency band (280) may be provided to the antenna (330) through the extraction circuit (320). A transmission signal of the first frequency band (280) can be radiated through the antenna (330). Depending on the embodiment, the switch circuit (326) may not be included in the electronic device (300).

[0063] According to one embodiment, a transmission signal in the n256 band may be provided from a port (211) to a switch circuit (326). A transmission signal in the n256 band may be provided from the switch circuit (326) to a filter (325). The filter (325) may be configured to pass a signal in the transmission frequency range of the n256 band. The filter (325) may correspond to the filter (223) of FIG. 2A. A transmission signal in the n256 band may be provided from the filter (325) to a port (214) of an RFFE module (210). A transmission signal in the n256 band may be provided from a port (214) of an RFFE module (210) to a port (217) of an RFFE module (210). A transmission signal in the n256 band may be provided to an antenna (330) through an extraction circuit (320). A transmission signal in the n256 band can be radiated through the antenna (330). For example, the n256 band can be distinguished from the frequency band extracted by the extraction circuit (320) (e.g., the second frequency band (290)). Thus, the transmission signal in the n256 band may not be affected by the characteristics of the extraction circuit (320).

[0064] According to one embodiment, the extraction circuit (320) may be configured to pass signals obtained from the RFFE module (210). The extraction circuit (320) may be configured to extract signals of the receiving frequency range (281) and the second frequency band (290) from the first frequency band (280). The signals of the receiving frequency range (281) and the second frequency band (290) may be provided to a low noise amplifier (321). The signals of the receiving frequency range (281) and the second frequency band (290) may be provided from the low noise amplifier (321) to the switch circuit (341) of FIG. 3a or the divider (342) (or splitter (342)) of FIG. 3b. For example, as described above, a filter having a passband that does not overlap with the transmitting frequency range (282) (e.g., n255Tx) may be used. Such a filter is included in the extraction circuit (320) to extract signals of the second frequency band (290) and the receiving frequency range (281) within the first frequency band (280). In various examples, for a specific frequency (e.g., a specific frequency range where the receiving frequency range (281) and the second frequency band (290) overlap), the signal extracted from the signal received through the antenna includes the signal of the second frequency band (290) and the signal of the receiving frequency range (281) within the first frequency band (280), and includes a component corresponding to the signal of the second frequency band (290) and a component corresponding to the signal of the receiving frequency range (281). That is, a portion of the signal received at this specific frequency may correspond to a combination (e.g., a combined amplitude) of two separate signals (i.e., one signal associated with the first frequency band (280) and another signal associated with the second frequency band (290).

[0065] For example, as in FIG. 3a, if the electronic device (300) includes a switch circuit (341), the electronic device (300) (or the processor of the electronic device (300), the RF transceiver of the electronic device (300)) can provide signals of the receiving frequency range (281) and the second frequency band (290) to one of the filter (324) and the filter (322) by controlling the switch circuit (341).

[0066] For example, as in FIG. 3b, if the electronic device (300) includes a divider (342), the electronic device (300) (or the processor of the electronic device (300), the RF transceiver of the electronic device (300)) can provide signals of the receiving frequency range (281) and the second frequency band (290) to both the filter (324) and the filter (322) through the divider (342).

[0067] According to one embodiment, signals of the receiving frequency range (281) and the second frequency band (290) may be provided to a filter (324) from the switch circuit (341) of FIG. 3a or the divider (342) of FIG. 3b. The filter (324) may be configured to pass the signal of the second frequency band (290). The signal of the second frequency band (290) that has passed through the filter (324) may be provided to a circuit (not shown) for signal processing regarding GNSS communication. The signal of the receiving frequency range (281) and the signal of the second frequency band (290) may not interfere with each other. For example, if the second frequency band (290) corresponds to a GPS frequency band and the receiving frequency range (281) corresponds to an n255Rx frequency band, the signal of one band may not interfere with the signal of the other band. The switch circuit (341) of FIG. 3a or the divider (342) of FIG. 3b can be used with a filter (324) and / or a filter (322) to separate signals according to frequency bands.

[0068] According to one embodiment, signals of the receiving frequency range (281) and the second frequency band (290) may be provided to a filter (322) from the switch circuit (341) of FIG. 3a or the divider (342) of FIG. 3b. The filter (322) may be configured to pass the signal of the receiving frequency range (281) among the first frequency band (280). The signal of the receiving frequency range (281) that has passed through the filter (322) may be provided to a port (212) of the RFFE module (210). The signal of the receiving frequency range (281) input to the port (212) may be processed by the RFFE module (210), an RF transceiver, and / or a processor.

[0069] As shown in FIGS. 3a and 3b, the electronic device (300) simultaneously receives a received signal of the first frequency band (280) and a received signal of the second frequency band (290), and can distinguish the received signal of the first frequency band (280) and the received signal of the second frequency band (290) using filters (324) and (322). For example, the extraction circuit (320) may include an extractor or a multiplexer. For example, the two components mentioned in the above example may be separated as a part that separates the received signal of the first frequency band (280) and the received signal of the second frequency band (290). To support the transmitted signal of the first frequency band (280) as a cell band, the extraction circuit (320) may be configured based on an acoustic filter of thinfilm SAW and / or BAW (bulk acoustic wave). For example, such a filter can filter the transmission frequency range (282) of the first frequency band (280).

[0070] FIG. 4 illustrates an example of an electronic device according to one embodiment.

[0071] Referring to FIG. 4, the electronic device (490) may include a processor (410), an RF transceiver (420), an RFFE module (430), and / or an antenna (440). The RFFE module (430) may correspond to the RFFE module (210) of FIG. 3a and FIG. 3b. The antenna (440) may correspond to the antenna (330) of FIG. 3a and FIG. 3b. Although not illustrated, the electronic device (490) may further include memory. For example, within the memory of the electronic device (490), one or more instructions (or commands) representing operations and / or actions to be performed on data by the processor (410) of the electronic device (490) may be stored. A set of one or more instructions may be referred to as firmware, an operating system, a process, a routine, a sub-routine, and / or an application. For example, the electronic device (490) and / or processor (410) may perform at least one of the operations according to the embodiments described below when a set of a plurality of instructions distributed in the form of an operating system, firmware, driver, and / or application is executed. Hereinafter, the statement that an application is installed in the electronic device (490) may mean that one or more instructions provided in the form of an application are stored in memory, and that said one or more applications are stored in an executable format (e.g., a file having an extension specified by the operating system of the electronic device (490)) by the processor (410). As an example, the application may include a program and / or library related to a service provided to a user.

[0072] For example, the processor (410) may include at least one of an application processor (AP) (e.g., the main processor (121) of FIG. 1) or a communication processor (CP) (e.g., the auxiliary processor (123) of FIG. 1). For example, the processor (410) may include an AP and a CP. For example, the processor (410) may include an AP. For example, the processor (410) may include a CP. The processor (410) may control the RF transceiver (420) through a control interface. The processor (410) may control the RF transceiver (420) so that a signal is transmitted through the antenna (440). The processor (410) may control the RF transceiver (420) so that a signal is received.

[0073] For example, the RF transceiver (420) may be implemented as part of a single chip (e.g., an RFIC chip) or a single package. The RF transceiver (420) may include a digital-to-analog converter (DAC) for converting a digital signal into an analog signal. The RF transceiver (420) may include a mixer and an oscillator (e.g., a local oscillator (LO) or a voltage-controlled oscillator (VCO)) for up-conversion. The RF transceiver (420) may convert a baseband signal generated by the processor (410) into an RF signal. The RF transceiver (420) may provide the RF signal to the RFFE module (430). The RF transceiver (420) may include an analog-to-digital converter (ADC) for converting an analog signal into a digital signal. The RF transceiver (420) may include a mixer and an oscillator for down-conversion. The RF transceiver (420) may convert an RF signal received from an antenna (440) into a baseband signal so that it can be processed by a processor (410). The RF transceiver (420) may include one or more transmission ports. The RF transceiver (420) may include one or more reception ports.

[0074] According to one embodiment, the RFFE module (430) may include a power amplifier (431), a switch circuit (432), an LNA (low noise amplifier) ​​(433), an LNA (435), a switch circuit (434), a switch circuit (436), a duplexer (437), a duplexer (438), and a switch circuit (439).

[0075] For example, the RF transceiver (420) may provide an RF signal of a third frequency band to the RFFE module (430) for a communication network (e.g., LTE (long term evolution) network, NR (new radio) network, or future network (e.g., B5G (beyond 5G) or 6G and later networks)). The RF signal of the third frequency band may be provided to the switch circuit (432) through a power amplifier (e.g., power amplifier (431)). The RF signal of the third frequency band may be provided from the switch circuit (432) to one of the duplexer (437) and the duplexer (438). The duplexer (437) may be configured to pass a signal of the B1 band of the third frequency band. The duplexer (438) may be configured to pass a signal of the B3 band of the third frequency band. A signal in the third frequency band may be provided to the switch circuit (439) from either the duplexer (437) or the duplexer (438). A signal in the third frequency band may be provided to the extraction circuit (450) from the switch circuit (439). The extraction circuit (450) (more generally referred to as the "circuit") may correspond to the extraction circuit (320) of FIGS. 3a and 3b. A signal in the third frequency band may be provided to the antenna (440) from the extraction circuit (450). A signal in the third frequency band may be radiated through the antenna (440).

[0076] For example, a signal in the third frequency band can be obtained through an antenna (440). The signal in the third frequency band can be provided from the antenna (440) to an extraction circuit (450). The signal in the third frequency band can be provided through the extraction circuit (450) to a switch circuit (439) of an RFFE module (430). The signal in the third frequency band can be provided from the switch circuit (439) to one of a duplexer (437) and a duplexer (438). The signal in the third frequency band can be provided from one of the duplexer (437) and a duplexer (438) to one of a switch circuit (434) and a switch circuit (436). The signal in the third frequency band can be provided to an RF transceiver (420) through one of a low-noise amplifier (433) and a low-noise amplifier (435). The signal of the third frequency band can be processed by an RF transceiver (420) and / or a processor (410).

[0077] For example, the RF transceiver (420) may provide a transmission signal (or transmission RF signal) of the first frequency band (280) to the RFFE module (430). The transmission signal of the first frequency band (280) may be provided to the switch circuit (432) through a power amplifier (e.g., power amplifier (431)). The transmission signal of the first frequency band (280) may be provided from the switch circuit (432) to the filter (451). The filter (451) may be configured to pass a signal of the transmission frequency range (282) of the first frequency band (280). The filter (451) may correspond to the filter (323) of FIGS. 3a and FIGS. 3b. The transmission signal of the first frequency band (280) that has passed through the filter (451) may be provided to the switch circuit (439). A transmission signal of the first frequency band (280) can be provided from the switch circuit (439) to the extraction circuit (450). The extraction circuit (450) can be configured to pass signals obtained from the RFFE module (430). The transmission signal of the first frequency band (280) that has passed through the extraction circuit (450) can be provided to the antenna (440). The transmission signal of the first frequency band (280) can be radiated through the antenna (440).

[0078] For example, signals of the first frequency band (280) and the second frequency band (290) can be acquired through the antenna (440). Signals of the first frequency band (280) and the second frequency band (290) can be provided to the extraction circuit (450) through the antenna (440). The extraction circuit (450) can be configured to extract signals of the receiving frequency range (281) and the second frequency band (290) from the first frequency band (280). Signals of the first frequency band (280) and the second frequency band (290) can be provided to the separation circuit (400) through the extraction circuit (450). Signals of the first frequency band (280) and the second frequency band (290) can be input to the port (403) of the separation circuit (400).

[0079] Through the separation circuit (400), signals of the first frequency band (280) and the second frequency band (290) can be separated into a signal (or received signal) of the first frequency band (280) and a signal of the second frequency band (290). The signal of the first frequency band (280) can be provided to the RFFE module (430) through the port (401). The signal of the second frequency band (290) can be provided to a circuit (not shown) for signal processing regarding GNSS communication through the port (402).

[0080] For example, a signal of the first frequency band (280) may be provided to a switch circuit (436). A signal of the first frequency band (280) may be provided from the switch circuit (436) to a low-noise amplifier (435). A signal of the first frequency band (280) may be provided from the low-noise amplifier (435) to an RF transceiver (420). A signal of the first frequency band (280) (or a received signal) may be processed by an RF transceiver (420) and / or a processor (410).

[0081] The electronic device (490) described above can simultaneously receive signals of the first frequency band (280) and signals of the second frequency band (290) and distinguish them through a separation circuit (400). Accordingly, the electronic device (490) can receive signals of the second frequency band (290) while receiving signals of the first frequency band (280). Additionally, since the path through which the signal of the first frequency band (280) is transmitted and the path through which the signal of the second frequency band (290) is distinguished are different, the electronic device (490) can receive signals of the second frequency band (290) while transmitting signals of the first frequency band (280).

[0082] In FIG. 4, an example is shown in which the extraction circuit (450), filter (451), and separation circuit (400) are distinguished from the RFFE module (430), but is not limited thereto. At least some or all of the extraction circuit (450), filter (451), and separation circuit (400) may be included in the RFFE module (430).

[0083] Specific examples of the separation circuit (400) will be described in FIGS. 5a and 5b below.

[0084] FIG. 5a illustrates an example of a separation circuit according to one embodiment.

[0085] FIG. 5b illustrates an example of a separation circuit according to one embodiment.

[0086] Referring to FIG. 5a, the separation circuit (400) may include a low-noise amplifier (421), a divider (442) (or splitter (442)), a filter (422), and / or a filter (424). For example, the separation circuit (400) may receive signals of a first frequency band (280) and a second frequency band (290) through a port (403). Through the low-noise amplifier (421), the signals of the first frequency band (280) and the second frequency band (290) may be amplified. The low-noise amplifier (421) may be placed to reduce losses during the signal separation process. The signals of the first frequency band (280) and the second frequency band (290) may be provided from the low-noise amplifier (421) to the divider (442).

[0087] For example, the divider (442) may be configured to separate an input signal according to a specified size ratio. For example, the divider (442) may be configured to branch the input path into a first branch and a second branch. A filter (422) may be connected to the first branch of the divider (442). A filter (424) may be connected to the second branch of the divider (442).

[0088] For example, signals of the first frequency band (280) and the second frequency band (290) may be provided to a filter (422). The filter (422) may be configured to pass signals of the receiving frequency range (281) of the first frequency band (280). Signals of the first frequency band (280) may pass through the filter (422). Signals of the first frequency band (280) may be output through a port (401).

[0089] For example, signals of the first frequency band (280) and the second frequency band (290) may be provided to a filter (424). The filter (424) may be configured to pass the signal of the second frequency band (290). The signal of the second frequency band (290) may pass through the filter (424). The signal of the second frequency band (290) may be output through a port (402).

[0090] Referring to FIG. 5b, the separation circuit (400) may include a low-noise amplifier (421), a switch circuit (441), a filter (422), and / or a filter (424). For example, the separation circuit (400) may receive signals of a first frequency band (280) and a second frequency band (290) through a port (403). Through the low-noise amplifier (421), the signals of the first frequency band (280) and the second frequency band (290) may be amplified. The low-noise amplifier (421) may be placed to reduce losses during the signal separation process. The signals of the first frequency band (280) and the second frequency band (290) may be provided from the low-noise amplifier (421) to the switch circuit (441).

[0091] For example, the switch circuit (441) may be configured to connect an input path to either a first terminal or a second terminal. A filter (422) may be connected to the first terminal of the switch circuit (441). A filter (424) may be connected to the second terminal of the switch circuit (441).

[0092] For example, signals of the first frequency band (280) and the second frequency band (290) may be provided to a filter (422). The filter (422) may be configured to pass signals of the receiving frequency range (281) of the first frequency band (280). Signals of the first frequency band (280) may pass through the filter (422). Signals of the first frequency band (280) may be output through a port (401).

[0093] For example, signals of the first frequency band (280) and the second frequency band (290) may be provided to a filter (424). The filter (424) may be configured to pass the signal of the second frequency band (290). The signal of the second frequency band (290) may pass through the filter (424). The signal of the second frequency band (290) may be output through a port (402).

[0094] FIG. 6 illustrates examples of a first frequency band, a second frequency band, and a passband of an extraction circuit according to one embodiment.

[0095] Referring to FIG. 6, the first frequency band (280) may correspond to the first frequency band (280) of FIG. 2b. The second frequency band (290) may correspond to the second frequency band (290) of FIG. 2b.

[0096] According to one embodiment, the passband of the extraction circuit (450) of FIG. 4 may correspond to a frequency band (670). For example, the frequency band (670) may include a receiving frequency range (281) of a first frequency band (280) and a second frequency band (290).

[0097] For example, the extraction circuit (450) may be configured to extract signals of the receiving frequency range (281) and the second frequency band (290) among the signals received through the antenna (440). The extraction circuit (450) may be configured to extract signals having a frequency within the frequency band (670) among the signals received through the antenna (440).

[0098] For example, the frequency band (670) may be set from frequency (671) to frequency (672). Frequency (671) may be set lower than frequency (283) of the receiving frequency range (281). Frequency (672) may be set higher than frequency (292) of the second frequency band (290). Frequency (672) may be set lower than frequency (285) of the transmitting frequency range (282). In various examples, the frequency band (670) (and / or the passband of the extraction circuit (450) of FIG. 4) may be set to correspond to a combined frequency range of, for example, a satellite communication frequency band and a frequency band associated with GNSS (e.g., a frequency band associated with GPS, a frequency band associated with GLONASS, a frequency band associated with Galileo, a frequency band associated with Beidou, or a frequency band associated with other types of geospatial positioning systems).

[0099] FIG. 7 illustrates a flowchart regarding the operation of an electronic device according to one embodiment. In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0100] Referring to FIG. 7, in operation 710, an electronic device (490) (or a processor (410) of the electronic device (490)) (e.g., user equipment, UE) can identify the location (or approximate location) of the electronic device (490) based on signals of a second frequency band (290). For example, the processor (410) can acquire signals of the second frequency band (290) using an extraction circuit (450) and / or a separation circuit (400). The processor (410) can identify the location of the electronic device (490) based on signals of the second frequency band (290).

[0101] According to one embodiment, the second frequency band (290) may be used for global navigation satellite system (GNSS) communication. Depending on the region or bandwidth used, GNSS communication may include at least one of GLONASS (global navigation satellite system), beidou navigation satellite system (hereinafter "Beidou"), QZSS (quasi-zenith satellite system), IRNSS (Indian regional satellite system), or Galileo (the European global satellite-based navigation system). For example, the processor (410) may receive signals of the second frequency band (290) from at least one satellite. Based on the signals of the second frequency band (290), the processor (410) may identify location information of the electronic device (490).

[0102] According to one embodiment, the processor (410) can receive signals of the second frequency band (290) while transmitting and / or receiving signals of the first frequency band (280) and can identify location information of the electronic device (490). For example, the processor (410) can receive signals of the second frequency band (290) while receiving signals of the receiving frequency range (281) of the first frequency band (280). For example, the processor (410) can receive signals of the second frequency band (290) while transmitting signals of the transmitting frequency range (282) of the first frequency band (280).

[0103] For example, the first frequency band (280) can be used for satellite communication. For example, satellite communication may be referred to as NB NTN (narrow band non-terrestrial network) communication (or NR NTN communication).

[0104] For example, the second frequency band (290) can be set between the transmission frequency range (282) of the first frequency band (280) and the reception frequency range (281) of the first frequency band (280).

[0105] In operation 720, the processor (410) can adjust an offset for signals in the transmission frequency range (282) within the first frequency band (280). For example, the offset may be referred to as a timing advance (TA). The processor (410) can change the TA to transmit signals in the transmission frequency range (282) to the satellite. The processor (410) can change the TA to transmit signals in the transmission frequency range (282) within a specified time resource according to UL scheduling information received from the satellite.
