Description

Electronic device for transmitting radio frequency signals, method of operation thereof, and storage medium

[0001] The present disclosure relates to an electronic device for transmitting a radio frequency (RF) signal, a method of operating the same, and a storage medium.

[0002] An electronic device can transmit multiple types of RF signals. For example, a physical channel for an RF signal can include at least one of a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), a physical random access channel (PRACH), and a sounding reference signal (SRS). The electronic device can transmit each of the PUSCH RF signal, the PUCCH RF signal, the PRACH RF signal, and the SRS using resources allocated to each uplink channel.

[0003] Meanwhile, the transmission power for each uplink physical channel may be set differently. Accordingly, as RF signals corresponding to each uplink physical channel are transmitted, the transmission power of the RF signal may be changed. The electronic device may include at least one power amplifier (PA) for amplifying the RF signal. Modes for controlling the driving voltage (Vcc) applied to the PA based on the transmission power of the RF signal include an envelope tracking (ET) mode and an average power tracking (APT) mode. In the APT mode, the supply voltage may be controlled based on the transmission power of the RF signal, and the supply voltage may be controlled in units of time of a slot (or subframe). Meanwhile, in the ET mode, the supply voltage may be controlled by tracking the transmission power of the RF signal in real time.

The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), 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), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the 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 eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0106] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In 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 the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the at least one selected antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0107] According to various embodiments, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0108] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0109] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via 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 executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an 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 process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in 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.

[0110] FIG. 2A is a block diagram (200) of an electronic device (101) for supporting legacy network communication and 5G network communication according to various embodiments. 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).

[0111] 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. According to various embodiments, 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. According to various embodiments, 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.

[0112] The first communication processor (212) can transmit and receive data with the second communication processor (214). For example, data classified to be 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).

[0113] 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.

[0114] 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. According to various embodiments, the first communication processor (212) or the second communication processor (214) may be formed in a single chip or a single package with the processor (120), the auxiliary processor (123), or the communication module (190). For example, as shown in FIG. 2B, the integrated communication processor (260) may support functions for communicating with both the first cellular network (292) and the second cellular network (294).

[0115] 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 various embodiments, and a processing circuit (or, the name thereof is not limited, such as an arithmetic circuit) for executing the instructions.

[0116] The first RFIC (222) may, upon transmission, convert a baseband signal generated by the first communication processor (212) into a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in a first cellular network (292) (e.g., a legacy network). Upon reception, the RF signal may be acquired from the first 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).

[0117] 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).

[0118] 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).

[0119] 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.

[0120] 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 various embodiments, 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.

[0121] In 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).

[0122] In one embodiment, 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). Upon 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. Upon 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.

[0123] 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)).

[0124] FIG. 3A illustrates a block diagram of an electronic device including a power amplifier according to various embodiments. The embodiment of FIG. 3A will be described in more detail with reference to FIGS. 4A to 4C. FIGS. 4A to 4C are diagrams for explaining the operating modes of a power management integrated circuit (PMIC) according to various embodiments.

[0125] According to various embodiments, the electronic device (101) may include at least one of an application processor (301), a communication processor (310), an RFIC (320), a power amplifier (330), an antenna (340), a PMIC (350), or a capacitor (361).

[0126] According to one embodiment, the communication processor (310) (e.g., at least one of the first communication processor (212), the second communication processor (214), or the integrated communication processor (260)) may provide a baseband signal for transmission to an RFIC (320) (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 (310) may receive and process a baseband signal for reception from the RFIC (320).

[0127] According to one embodiment, the application processor (301) may check the device status index (DSI) of the electronic device (101). The DSI may include, for example, an index (RCV) indicating that a receiver (or speaker) is operating, an index (CAM) indicating that a camera is operating, an index (GRIP) indicating that the electronic device (101) is gripped by a user, an index (HOTSPOT) indicating that a hot-spot function is activated, an index (USB) indicating that a universal series bus (USB) connector is connected, an index (WIFI) indicating that a Wi-Fi function is activated, or an index indicating a form factor (or current shape) of the electronic device (101), but there is no limitation on the type and / or number thereof. The application processor (301) may provide the checked DSI to the communication processor (310).

[0128] The communication processor (310) may determine one or more values ​​associated with the operation of the PA (330) based on parameters related to the DSI and / or communication. The parameters related to the communication may include, for example, radio access technology (RAT), frequency band, number of resource blocks (RBs), starting points of RBs, and / or bandwidth part (BWP) related information, but there is no limitation on their type and / or number. The one or more values ​​associated with the operation of the PA (330) may include, for example, a driving voltage (or, may be referred to as a bias voltage), a reference gain index (RGI), a quiescent collector current (ICQ), and / or a digital pre-distortion (DPD) index (IDX) of the PA (330), but there is no limitation. For example, the communication processor (310) may determine whether to set one or more values ​​associated with the operation of the PA (330) using parameters associated with the linearity of the PA (330) based on parameters related to DSI and / or communication, as will be described later. The parameters associated with linearity may be determined based on a feedback signal provided through a coupler (370), as will be described later. The communication processor (310) may control the RFIC (320), the PA (330), and / or the PMIC (350) based on the determined values.

[0129] According to one embodiment, the RFIC (320) may generate an RF signal corresponding to, for example, a baseband signal for transmission and provide the RF signal to the power amplifier (330). Although FIG. 3A illustrates that the baseband signal for transmission is provided to the RFIC (320) through a single line, this is exemplary and those skilled in the art will appreciate that baseband signals of an in-phase (I) component and a quadrature (Q) component may be provided to the RFIC (320). The power amplifier (330) may also 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. In FIG. 3A, a power amplifier (330) is illustrated as being connected to an RFIC (320), but those skilled in the art will understand that, in addition to the power amplifier (330), a filter and / or an antenna switching module (ASM) may be further included in the RFFE. Meanwhile, in FIG. 3A, one RFIC (320), one power amplifier (330), and one antenna (340) are illustrated as being included in the electronic device (101), but this is for convenience of explanation, and those skilled in the art will understand that a plurality of RFICs, power amplifiers, and antennas may be implemented to be included in the electronic device (101). Meanwhile, the RFFE including the RFIC (320) and power amplifier (330) in FIG. 3a may also be referred to as an RF circuit (390).

[0130] According to one embodiment, the PMIC (350) (e.g., at least one of a buck / boost converter, a buck converter, or a boost converter) may provide a supply voltage (Vcc) to the power amplifier (330) using the supplied power. The power amplifier (330) may amplify an RF signal provided from the RFIC (320) using the supply voltage (Vcc). The PMIC (350) may be configured to operate, for example, according to the APT mode. Alternatively, the PMIC (350) may operate in the direct mode or the ET mode. When operating in the ET mode, the PMIC (350) may be replaced with a linear amplifier, which will be described with reference to FIG. 3B. In one example, when operating in the direct mode, the supply voltage (Vcc) (401) of the power amplifier (330) may be set to a specified value, as in FIG. 4A. In direct mode, a supply voltage (401) of a specified value can be provided to the power amplifier (330) regardless of the size of the transmission power per signal. In this case, the wasted power consumption can be relatively large. In another example, when operating according to the APT mode, the supply voltage (Vcc) (402) of the power amplifier (330) can 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 can be supplied to the power amplifier (330), 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 can be supplied to the power amplifier (330). In another example, when operating in ET mode, the supply voltage (Vcc) (403) of the power amplifier (330) can be set (or changed) in real time according to the size of the transmission power of the RF signal, as in FIG. 4c.When operating in ET mode, the PMIC (350) can track the transmission power of the RF signal in real time and provide a supply voltage corresponding to the envelope of the transmission power to the power amplifier (330). The time interval of setting (or changing) the supply voltage (Vcc) in ET mode can be shorter than the time interval of setting (or changing) the supply voltage (Vcc) in APT mode. The communication processor (310) (or modulator) can, for example, provide a value based on the I / Q signal of the baseband signal (. ) 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.

[0131] According to one embodiment, the PMIC (350) may provide a supply voltage (Vcc) to the power amplifier (330) for transmitting an RF signal according to the APT mode. For example, the PMIC (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 PMIC (350). For example, when an RF signal of an ultra high band (UHB) or an operating band with a relatively wide bandwidth (e.g., a B48 band, a B42 band, an N48 band, an N41 band, an N77 band, an N78 band, or an N79 band) is transmitted, the APT mode may be used, but there is no limitation. The PMIC (350) can control the charge and / or discharge amount of the capacitor (361) to supply a determined supply voltage (Vcc).

[0132] The communication processor (310) and / or the RFIC (320) can check the driving voltage as a value (or control information) associated with the driving of the PA (330), and the PMIC (350) can be controlled to provide the checked driving voltage. The communication processor (310) and / or the RFIC (320) can determine RGI, IDX, and / or ICQ as values ​​(or control information) associated with the driving of the PA (330), and can be controlled accordingly. Through the above-described process, the RF signal provided by the RFIC (320) can be amplified by the PA (330). The RF signal can be amplified by the PA (330) and provided to the antenna (340). Meanwhile, a feedback signal corresponding to the RF signal can be provided to the RFIC (320) through the coupler (370). The communication processor (310) and / or the RFIC (320) may determine a parameter associated with linearity based on the strength of the feedback signal. As will be described later, the communication processor (310) and / or the RFIC (320) may also adjust a value associated with driving the PA (330) (e.g., but not limited to, driving voltage, ICQ, RGI, and / or IDX) based on the parameter associated with linearity.

[0133] FIG. 3b illustrates a block diagram of an electronic device including a power amplifier according to various embodiments.

[0134] According to one embodiment, the electronic device (101) may include at least one of a first converter (350a), a first linear amplifier (350b), a second linear amplifier (350c), or a second converter (350d). A capacitor (361a) may be connected to the first converter (350a). The first converter (350a) may be connected to a power amplifier (330a) via a coil (362a). The first converter (350a) may be, for example, a buck / boost converter, but is not limited thereto. The first converter (350a) may apply or stop applying a driving voltage (Vcc) determined, for example, according to an APT mode, to the capacitor (361a) using a voltage from the battery (189) (or PMIC). The driving voltage (Vcc) applied to the capacitor (361a) can be input to the power amplifier (330a). In the APT mode, the size of the driving voltage (Vcc) can be determined, for example, in units of 1 ms, but there is no limitation. If the capacitor (361a) is not present, the output voltage may not be output as a constant value and may be switched. Accordingly, the capacitor (361a) may be an element essentially required in the APT mode. The power amplifier (330a) may be used exclusively for the APT mode, but there is no limitation.

[0135] According to one embodiment, the switch (380) can selectively connect the capacitor (361a) to the power amplifier (330b) and / or the power amplifier (330c). For example, the power amplifier (330b) and / or the power amplifier (330c) can be applied with a driving voltage (Vcc) determined according to either the APT mode or the ET mode. When the power amplifier (330b) and / or the power amplifier (330c) operates in the APT mode, the switch (380) can be controlled to be in an on state. For example, the power amplifier (330b) can amplify an RF signal based on a first RAT (e.g., E-UTRA), and the power amplifier (330c) can amplify an RF signal based on a second RAT (e.g., NR), but there is no limitation. When processing of an RF signal based on the first RAT (e.g., E-UTRA) is determined to be in the APT mode, the driving voltage (Vcc) applied to the capacitor (361a) by the first converter (350a) can be provided to the power amplifier (330b) through the switch (380) and the coil (362b). When processing of an RF signal based on the second RAT (e.g., NR) is determined to be in the APT mode, the driving voltage (Vcc) applied to the capacitor (361a) by the first converter (350a) can be provided to the power amplifier (330c) through the switch (380) and the coil (362c).

[0136] Meanwhile, when the power amplifier (330b) and / or the power amplifier (330c) operates in the ET mode, the switch (380) may be controlled to be off. When the switch (380) is controlled to be off, the linear amplifiers (350b, 350c) may provide a driving voltage (Vcc) that changes in real time to the power amplifier (330b) and / or the power amplifier (330c). The linear amplifier (350b) may provide a driving voltage (Vcc) for amplifying an RF signal based on a first RAT (e.g., E-UTRA), and the linear amplifier (350c) may provide a driving voltage (Vcc) for amplifying an RF signal based on a second RAT (e.g., NR), but there is no limitation. The second converter (350d) may be implemented as a slow converter in one example and may provide a DC current. The second converter (350d) may operate in ET mode and may not operate in APT mode. The linear amplifiers (350b, 350c) may be connected to a capacitor (381). The capacitor (381) may be connected to each of the power amplifiers (330b, 330c) via a coil (362b) and a coil (362c).

[0137] Figures 5a and 5b are drawings for explaining parameters related to the linearity of PA.

[0138] Referring to FIG. 5A, for example, the electronic device (101) may perform communication based on a first frequency (f1). In this case, the electronic device (101) may control the RF circuit (390) so that the RF signal (501) of the first frequency (f1) is amplified through, for example, the PA (330) of FIG. 3A and provided to the antenna (340). For example, the electronic device (101) may assume that the driving voltage of the PA (330) is set to the first value. Meanwhile, when the RF signal (501) of the first frequency (f1) is generated, unwanted signals (511, 513) may be generated in adjacent channels (e.g., f1-1, f1-2). The unwanted signals (511, 513) may cause a deterioration in the linearity of the PA (330). The linearity of the PA (330) is a feature that must be guaranteed for high-quality communication, and a decrease in linearity is undesirable. Accordingly, the electronic device (101) can set a value associated with the operation of the PA (330) so that the size of the unwanted signals (511, 513) is maintained below a threshold size (510).

[0139] For example, the magnitude of the unwanted signals (511, 513) may have a negative correlation with the driving voltage of the PA (330). For example, the larger the driving voltage of the PA (330), the smaller the magnitude of the unwanted signals (511, 513), and the smaller the driving voltage of the PA (330), the larger the magnitude of the unwanted signals (511, 513). In order to suppress the unwanted signals (511, 513), an increase in the driving voltage of the PA (330) may be required. For example, as in FIG. 5A, as the magnitude of the unwanted signals (511, 513) exceeds the threshold magnitude (510), the magnitude of the driving voltage of the PA (330) needs to be set to a value larger than the first value.

[0140] Referring to FIG. 5B, for example, the electronic device (101) can perform communication based on a first frequency (f1). For example, the electronic device (101) assumes that the driving voltage of the PA (330) is set to a second value. When an RF signal (521) of the first frequency (f1) is generated, unwanted signals (531, 533) in adjacent channels (e.g., f1-1, f1-2) may be generated. Since the second value, which is the driving voltage of the PA (330) in FIG. 5B, is greater than the first value, which is the driving voltage of the PA (330) in FIG. 5A, the magnitudes of the unwanted signals (531, 533) in the example of FIG. 5B may be smaller than the magnitudes of the unwanted signals (511, 513) in the example of FIG. 5A. The sizes of the unwanted signals (531, 533) in the example of FIG. 5B may be, for example, smaller than the threshold size (510). The electronic device (101) may perform calibration corresponding to parameters associated with communication and / or DSI, and may store a second value according to the calibration result as the driving voltage of the PA (330). Thereafter, the electronic device (101) may control the RF circuit (390) so that the driving voltage of the second value stored as the calibration result is provided to the PA (330) based on satisfaction of the corresponding condition (e.g., parameters associated with communication and / or DSI).

[0141] However, even if the margins (ΔM1, ΔM2) for the parameters related to linearity are relatively large, there is a possibility that the power of the electronic device (101) will be consumed relatively quickly as the values ​​set as the calibration results are used. The margins (ΔM1, ΔM2) for the parameters related to linearity are expressed as the difference between the threshold size (510) and the sizes of the unwanted signals (531, 533) in the example of FIG. 5b, but this is by way of example only and there is no limitation on the expression method and / or number of the margins for the parameters related to linearity. Examples of the parameters related to linearity and / or examples of the margins will be described later.

[0142] For example, providing a relatively large driving voltage may cause a relatively large power consumption. The electronic device (101) may control to reduce the driving voltage of the PA (330) when the margin (ΔM1, ΔM2) for the linearity-related parameter is relatively large. As will be described later, for example, the electronic device (101) may adjust the driving voltage based on the margin (ΔM1, ΔM2) for the linearity-related parameter. For example, when the linearity-related parameter and / or the corresponding margin satisfy the driving voltage reduction condition (for example, the condition may indicate that the margin is relatively large, but there is no limitation), the electronic device (101) may control the RF circuit (390) to reduce the driving voltage of the PA (330). For example, if a parameter related to linearity and / or a corresponding margin satisfies a driving voltage increase condition (for example, a condition indicating that the margin is relatively small, but there is no limitation), the electronic device (101) can control the RF circuit (390) to increase the driving voltage of the PA (330). As described above, the driving voltage of the PA (330) can be optimized, and power consumption can also be optimized. The optimized driving voltage can be lower than the driving voltage set according to the calibration result described in Table 1.

[0143] FIG. 6 is a drawing for explaining an operation method of an electronic device according to one embodiment.

[0144] According to one embodiment, the electronic device (101) may, in operation 601, identify at least one parameter (e.g., may be referred to as a network parameter) for communication with a network. For example, the at least one parameter for communication with a network may include information related to a radio access technology (RAT), a frequency band, a number of resource blocks (RBs), a starting point of an RB, and / or a BWP, but there is no limitation on the type and / or number thereof. In operation 603, the electronic device (101) may identify an antenna among one or more antennas included in the electronic device (101) and identify a PA among one or more PAs included in the electronic device (101) based on the identified at least one parameter. For example, the electronic device (101) may identify an antenna corresponding to a RAT and a frequency band. Each of one or more antennas included in the electronic device (101) may be configured with a frequency band to support, and accordingly, the electronic device (101) may select an antenna corresponding to the frequency band to be used. For example, the electronic device (101) may identify a PA configured corresponding to the antenna. Those skilled in the art will understand that the selection of the antenna and / or PA may be expressed, for example, as the selection of a transmission RF path. Meanwhile, the electronic device (101) may also identify the antenna and PA based on the DSI. For example, the electronic device (101) may identify the antenna by performing an antenna change (hopping or switching) based on the occurrence of a grip event, and there is no limitation on the DSI associated with the antenna identification. The electronic device (101) may select one antenna and one PA.Those skilled in the art will appreciate that the electronic device (101) may select multiple antennas and multiple PAs, for example, for communication using multiple antennas (e.g., carrier aggregation (CA), dual connectivity (DC), but not limited thereto). For example, for convenience of explanation, it is assumed that the antenna (340) of FIG. 3A and its corresponding PA (330) are selected based on parameters for communication.

[0145] The electronic device (101) may control the RF circuit (390) so that, in operation 605, the first transmission signal is amplified by the identified PA and provided to the identified antenna as the identified PA operates based on the first value associated with the PA driving. The value associated with the PA driving may include, but is not limited to, a driving voltage (or may be referred to as a bias voltage), a reference gain index (RGI), a quiescent collector current (ICQ), and / or an index (IDX). The first value may be, for example, a value identified by applying an algorithm for adjusting a value associated with the PA driving. The first value may be, for example, a default value. The first value may be, for example, a result calibrated for the electronic device (101). As described above, there is no limitation on the first value associated with the PA driving in operation 605.

[0146] The electronic device (101) can, in operation 607, determine a parameter associated with the linearity of the identified PA (330) based on a feedback value associated with the first transmission signal provided through the coupler (470) connected to the identified antenna (340). For example, the electronic device (101) can determine the strength of unwanted signals as a parameter associated with linearity, as described with reference to FIGS. 5A and 5B . Meanwhile, there is no limitation on the type and / or number of parameters associated with linearity. For example, the parameter associated with linearity may include an adjacent channel leakage ratio (ACLR). The ACLR may be, for example, a power level difference (dBc) between an adjacent channel spaced apart from a center frequency and may mean, for example, a power ratio leaked into the frequency band of the adjacent channel by a carrier signal at the center frequency. For example, the parameter associated with linearity may include a spectrum mask (SEM). SEM can be set based on the comparison result with the actual signal by setting a reference mask of a measured signal or service on the spectrum to evaluate the occupied bandwidth of a radio signal. Parameters associated with linearity may include error vector magnitude (EVM). EVM may be a measure of the modulation quality of a modulated signal within a certain spectrum band in a wireless digital communication method. For example, it may be a parameter for expressing the similarity between an actually transmitted signal and an ideal reference signal in a digital communication system, and may be, for example, the magnitude of the difference between an ideal waveform and a measured waveform. Meanwhile, the parameters associated with linearity described above are merely exemplary, and there is no limitation on their type and / or number.

[0147] The electronic device (101), in operation 609, may change a value associated with the PA drive from a first value to a second value based on a condition satisfied by a difference between a parameter associated with the linearity of the identified PA (330) and a threshold value (e.g., the threshold size (510) described in FIGS. 5A and 5B , but without limitation). For example, the electronic device (101) may change the value associated with the PA drive from the first value to a second value greater than the first value based on the condition satisfied by the difference between the parameter associated with the linearity of the identified PA (330) and the threshold value being a first condition for increasing the value associated with the PA drive. For example, the first condition may be, but without limitation, a condition indicating that a difference between a parameter associated with the linearity and a threshold value (e.g., the threshold size (510) described in FIGS. 5A and 5B , but without limitation) is relatively large (or may be expressed as a relatively large margin). For example, the electronic device (101) can change the value associated with the PA operation from the first value to a second value smaller than the first value, based on the condition that the difference between the parameter associated with the linearity of the verified PA (330) and the threshold value is satisfied, which is a second condition for decreasing the value associated with the PA operation. For example, the second condition can be, but is not limited to, a condition indicating that the difference between the parameter associated with the linearity and the threshold value (which can be, but is not limited to, the threshold size (510) described in FIGS. 5A and 5B ) is relatively small (or, the margin can be expressed as being relatively small). Meanwhile, although it has been described that the difference between the parameter and the threshold value in operation 609 is verified, and the condition that the verified difference is satisfied is verified, this is exemplary.The electronic device (101) may, in place of operation 609, determine to change the value associated with the PA drive from the first value to the second value based on a condition satisfied by a parameter associated with the linearity of the identified PA, and it will be understood by those skilled in the art that such a replacement of the operation is possible not only in the present embodiment but also in other embodiments. In operation 611, the electronic device (101) may control the RF circuit (390) so that the second transmission signal is amplified by the identified PA (330) and provided to the identified antenna (340) as the identified PA (330) operates based on the second value associated with the PA drive. As described above, the electronic device (101) can adjust the value associated with the driving of the PA (330) based on the difference (or margin) between the parameter associated with linearity and the threshold (e.g., the threshold size (510) described in FIGS. 5A and 5B, but without limitation), so that the amount of power consumed for the driving of the PA (330) can be optimized.

[0148] FIG. 7A is a drawing for explaining an operation method of an electronic device according to one embodiment.

[0149] According to one embodiment, the electronic device (101) may, in operation 701, verify at least one parameter for communication with a network. In operation 703, the electronic device (101) may verify, for example, the antenna (340) and the PA (330) of FIG. 3A based on the verified at least one parameter. In operation 705, the electronic device (101) may control the RF circuit (390) so that the first transmission signal is amplified by the verified PA (330) and provided to the verified antenna (340) as the verified PA operates based on the driving voltage of the first value. As described with reference to FIG. 6, there is no limitation on the method of setting the first value. In operation 707, the electronic device (101) may verify whether a driving voltage increase condition is satisfied. If the driving voltage increase condition is satisfied (operation 707 - Yes), the electronic device (101) can increase the driving voltage in operation 709. If the driving voltage increase condition is not satisfied (operation 707 - No), the electronic device (101) can check whether the driving voltage decrease condition is satisfied in operation 711. If the driving voltage decrease condition is satisfied (operation 711 - Yes), the electronic device (101) can decrease the driving voltage in operation 713. Meanwhile, in FIG. 7A, whether the driving voltage increase condition is satisfied is first determined as in operation 707, and then whether the driving voltage decrease condition is satisfied is determined as in operation 711. However, this is exemplary, and those skilled in the art will understand that the judgment order of the two conditions may be changed and may be performed in parallel depending on the implementation. If the driving voltage reduction condition is not satisfied (operation 711 - No), the electronic device (101) can store the value of the driving voltage in operation 715.The stored value may be directly used as the driving voltage of the PA (330), for example, under certain conditions of parameters for communication, as described with reference to FIG. 7B. Those skilled in the art will understand that, depending on the implementation, the storage of the optimized driving voltage in operation 715 may be omitted. The optimized driving voltage may be stored, for example, in the EFS (elastic file system) area, but this is merely exemplary and not limiting.

[0150] For example, the condition for increasing the driving voltage in the 707 operation may be a condition that the difference (or, which may be named as margin) between the parameter associated with linearity and the threshold for maintaining linearity is less than a first threshold (e.g., N + 2). For example, the condition for increasing the driving voltage may be expressed as 'margin < N + 2 ?' For example, the condition for decreasing the driving voltage in the 709 operation may be a condition that the difference (or, which may be named as margin) between the parameter associated with linearity and the threshold for maintaining linearity is greater than a second threshold (e.g., N). For example, the condition for increasing the driving voltage may be expressed as 'margin > N ?' Depending on whether the conditions described above are satisfied or not, the increase and / or decrease of the driving voltage may converge to a range exceeding the second threshold value and less than the first threshold value (e.g., exceeding N and less than N+2), and the range may be named an optimization range for the margin, and the driving voltage in which the margin is included in the optimization range may be named an optimized driving voltage.

[0151] For example, the increase and / or decrease of the driving voltage in operation 709 and / or operation 711 may be performed according to a specified unit size (e.g., 0.1 V, but there is no limitation). For example, if a condition for increasing the driving voltage is satisfied, the driving voltage may increase by 0.1 V compared to before, and if a condition for decreasing the driving voltage is satisfied, the driving voltage may decrease by 0.1 V compared to before. Alternatively, the size of the increase and / or decrease of the driving voltage may depend on the size of a parameter associated with the verified linearity.

[0152] Meanwhile, although in FIG. 7a the adjustment of the driving voltage is described based on parameters associated with linearity, those skilled in the art will appreciate that values ​​associated with PA driving other than the driving voltage (e.g., RGI, ICQ, and / or IDX) may alternatively and / or additionally be controlled, and this may also apply to other embodiments.

[0153] FIG. 7b is a drawing for explaining an operation method of an electronic device according to one embodiment.

[0154] According to one embodiment, the electronic device (101) may, in operation 721, identify at least one parameter for communication with a network. In operation 723, the electronic device (101) may identify, for example, an antenna (340) and a PA (330) as in FIG. 3A, based on the identified at least one parameter. In operation 725, the electronic device (101) may, in response to the identified at least one parameter, identify whether a stored value or an optimized driving voltage exists according to the adjustment of the driving voltage. For example, the electronic device (101) may adjust the driving voltage based on a parameter associated with linearity as described in FIG. 7A, and the optimized driving voltage according to the adjustment may be stored in the electronic device (101). If an adjustment as in FIG. 7A is performed in response to a parameter for communication, the optimized driving voltage corresponding to the corresponding parameter may be stored in the electronic device (101). If an adjustment such as that in FIG. 7A has not been performed in response to a parameter for communication, the optimized driving voltage corresponding to the parameter is not stored in the electronic device (101). If there is a stored value corresponding to at least one identified parameter (Operation 725 - Yes), the electronic device (101) can, in operation 727, identify a value associated with PA driving based on a pre-stored value corresponding to at least one identified parameter. If there is no stored value corresponding to at least one identified parameter (Operation 725 - No), the electronic device (101) can, in operation 729, identify a value associated with PA driving based on a parameter associated with linearity of the PA. For example, the electronic device (101) can perform an operation for optimization of increasing or decreasing a value associated with PA driving based on a parameter associated with linearity, as described in FIG. 7A, and thus an optimal value of a value associated with PA driving can be determined.

[0155] FIG. 7c is a drawing for explaining an operation method of an electronic device according to one embodiment.

[0156] According to one embodiment, the electronic device (101) may, in operation 741, identify at least one parameter for communication with a network. In operation 743, the electronic device (101) may identify, for example, an antenna (340) and a PA (330) as in FIG. 3A, based on the identified at least one parameter. In operation 745, the electronic device (101) may identify whether to identify a value associated with PA driving based on a parameter associated with linearity of the PA. For example, the electronic device (101) may store a value associated with PA driving based on a calibration result as described above. For example, Table 1 is an example of a value associated with PA driving based on a calibration result pre-stored in the electronic device (101).

[0157] Table 1

[0158]

[0159] The electronic device (101) may pre-store parameters associated with communication for determining values ​​associated with PA operation, for example, based on parameters associated with PA linearity. For example, Table 2 is an example of parameters associated with communication for determining values ​​associated with PA operation, for example, based on parameters associated with PA linearity.

[0160] Table 2

[0161]

[0162] The first mode in Table 2 may be a mode that determines values ​​associated with PA driving based on parameters associated with the linearity of the PA, for example, and may be named an adaptive mode as it adaptively adjusts values ​​associated with PA driving.

[0163] For example, as in Table 1, the electronic device (101) can store a value based on a calibration result corresponding to the frequency band of B41. Meanwhile, the electronic device (101) can confirm that the value associated with PA operation is determined based on a parameter associated with linearity of the PA for the frequency band of B41, as in Table 2. When information (e.g., Table 1) according to a calibration result related to the B41 band and information (e.g., Table 2) indicating operation in the first mode are confirmed, the electronic device (101) can operate according to the information (e.g., Table 2) indicating operation in the first mode rather than the information (e.g., Table 1) according to the calibration result. Accordingly, the electronic device (101) can set (or adjust) a value associated with PA operation based on a parameter associated with linearity, even though a value according to a calibration result related to the B41 frequency band is stored.

[0164] Alternatively, the electronic device (101) may determine to set a value associated with PA driving based on a parameter associated with linearity based on whether the parameter associated with linearity satisfies a specified condition. For example, the electronic device (101) may primarily set a value associated with PA driving based on a value based on a calibration result such as Table 1. For example, when the target power is set to 24 dBm, the electronic device (101) may set the driving voltage to 4339 mV with reference to information such as Table 1. The electronic device (101) may control the RF circuit (390) (e.g., PMIC (350)) so that the driving voltage of 4339 mV is provided. The electronic device (101) may determine the parameter associated with linearity based on a feedback signal obtained through the coupler (370) while the driving voltage of 4339 mV is provided. For example, if a parameter related to linearity satisfies a condition for increasing the driving voltage (e.g., if the margin is relatively large), the electronic device (101) may adjust the driving voltage based on the parameter related to linearity, for example, as in FIG. 7A. As described above, the method for determining whether to check a value associated with PA driving based on the parameter related to linearity in operation 745 may vary and is not limited. If it is determined that a value associated with PA driving is to be checked based on the parameter related to linearity (operation 745 - Yes), the electronic device (101) may check a value associated with PA driving based on the parameter related to linearity, for example, as in FIG. 7A, in operation 747. If it is not determined that a value associated with PA driving is to be checked based on the parameter related to linearity (operation 745 - No), the electronic device (101) may check a value associated with PA driving based on one of at least one pre-stored value in operation 749.For example, the electronic device (101) can check a value associated with PA operation based on a value stored based on a calibration result such as Table 1. For example, the electronic device (101) can also check a value associated with PA operation based on a value different from a value stored based on the calibration result, which will be described later.

[0165] For example, a value associated with the drive adjusted as described in FIG. 7a, for example, a drive voltage, may be less than a drive voltage set according to the calibration results described in Table 1.

[0166] FIG. 8 is a drawing for explaining an operating method of an electronic device according to one embodiment.

[0167] According to one embodiment, the electronic device (101) may, in operation 801, identify at least one parameter for communication with a network. In operation 803, the electronic device (101) may identify, for example, an antenna (340) and a PA (330) as in FIG. 3A, based on the identified at least one parameter. In operation 805, the electronic device (101) may control the RF circuit (390) such that a first transmission signal is amplified by the identified PA (330) and provided to the identified antenna (340) as the identified PA operates based on a first value associated with PA driving. In operation 807, the electronic device (101) may identify a parameter associated with linearity of the identified PA based on a feedback value associated with the first transmission signal provided through the coupler (370) connected to the identified antenna. The electronic device (101), in operation 809, may identify a value associated with PA operation as a second value in response to a parameter associated with the linearity of the PA identified among a plurality of conditions. For example, the electronic device (101) may identify the second value corresponding to the parameter associated with the linearity identified in operation 807 by referencing association information (e.g., a lookup table) between the parameter associated with PA linearity and the value associated with PA operation. For example, the electronic device (101) may identify the second value identified by inputting the parameter associated with PA linearity into an artificial intelligence model. The artificial intelligence model may be trained to receive, for example, the parameter associated with PA linearity as an input value and output a value associated with PA operation corresponding thereto. The value associated with PA operation may be a value such that a margin corresponding to the parameter associated with PA linearity is included in an optimal range (for example, N to N+2 as described in FIG. 7A, but without limitation), but this is exemplary and not limiting.Those skilled in the art will understand that the AI ​​model may alternatively and / or additionally receive at least some of the parameters for communication as input values ​​in addition to the parameters associated with the PA linearity, and there is no limitation on the type of the AI ​​model. For example, the AI ​​model may be an AI model having fixed parameters, or an AI model based on reinforcement learning. In operation 811, the electronic device (101) may control the RF circuit (390) so that the second transmission signal is amplified by the identified PA (330) and provided to the identified antenna (340) as the identified PA operates based on the second value associated with the PA operation.

[0168] FIG. 9 is a drawing for explaining an operating method of an electronic device according to one embodiment.

[0169] According to one embodiment, the electronic device (101) may, in operation 901, check at least one parameter for communication with a network. The electronic device (101) may, in operation 903, check a device status index (DSI). The DSI may include, for example, an index (RCV) indicating that a receiver (or speaker) is operating, an index (CAM) indicating that a camera is operating, an index (GRIP) indicating that the electronic device (101) is gripped by a user, an index (HOTSPOT) indicating that a hot-spot function is activated, an index (USB) indicating that a USB connector is connected, an index (WIFI) indicating that a Wi-Fi function is activated, or an index indicating a form factor (or current shape) of the electronic device (101), but there is no limitation on the type and / or number thereof. The electronic device (101) may, in operation 905, identify the antenna (340) and the PA (330) of FIG. 3A, for example, based on at least one identified parameter and the device state index, but is not limited thereto, and those skilled in the art will appreciate that the electronic device (101) may also select the antenna (340) and the PA (330) based on at least one parameter associated with the network. For example, the electronic device (101) may determine to adaptively adjust a value associated with the PA operation based on at least one parameter for communication and the DSI. For example, the electronic device (101) may determine a mode for identifying a value associated with the PA operation based on at least one parameter for communication and the DSI as a first mode, and the first mode and other modes will be described later.

[0170] In operation 907, the electronic device (101) may control the RF circuit (390) so that the first transmission signal is amplified by the identified PA (330) and provided to the identified antenna (340) as the identified PA (330) operates based on the first value associated with the PA driving. In operation 909, the electronic device (101) may identify a parameter associated with the linearity of the identified PA based on a feedback value associated with the first transmission signal provided through the coupler (370) connected to the identified antenna (340). In operation 911, the electronic device (101) may change the value associated with the PA driving from the first value to the second value according to a condition that a difference between the parameter associated with the linearity of the identified PA and a threshold value among a plurality of conditions is satisfied. The electronic device (101) can control the RF circuit (390) so that, in operation 913, the second transmission signal is amplified by the identified PA (330) and provided to the identified antenna (340) as the identified PA (330) operates based on the second value associated with the PA drive.

[0171] FIG. 10A is a drawing for explaining an operation method of an electronic device according to one embodiment.

[0172] According to one embodiment, the electronic device (101) may, in operation 1001, identify at least one parameter for communication with a network. In operation 1003, the electronic device (101) may identify, for example, the antenna (340) and the PA (330) of FIG. 3A based on the identified at least one parameter. In operation 1005, the electronic device (101) may determine whether to identify a value associated with PA operation based on a calibrated value for the electronic device (101) based on the identified at least one parameter. For example, the electronic device (101) may determine whether to identify a value associated with PA operation based on the calibrated value based on whether the at least one parameter for communication is a value set to identify a value associated with PA operation based on a parameter associated with linearity. For example, the electronic device (101) may store parameters associated with communication set to a first mode (e.g., a mode that verifies values ​​associated with PA operation based on parameters associated with linearity of the PA) as shown in Table 2. As described above, when information according to a calibration result related to the B41 band (e.g., Table 1) and information indicating operation in the first mode (e.g., Table 2) are verified, the electronic device (101) may operate according to the information indicating operation in the first mode (e.g., Table 2) rather than the information according to the calibration result (e.g., Table 1). Accordingly, the electronic device (101) may set (or adjust) values ​​associated with PA operation based on parameters associated with linearity, even though values ​​according to a calibration result related to the B41 frequency band are stored. Alternatively, as described above, the electronic device (101) may determine to set a value associated with PA driving based on a parameter associated with linearity, based on the parameter associated with linearity satisfying a specified condition.For example, if a parameter related to linearity satisfies a condition for increasing the driving voltage (e.g., if the margin is relatively large), the electronic device (101) may adjust the driving voltage based on the parameter related to linearity, for example, as in FIG. 7A. As described above, the method for determining whether to check the value associated with the PA driving based on the parameter related to linearity in operation 745 may vary and is not limited. When checking the value associated with the PA driving based on the calibrated value (operation 1005 - Yes), the electronic device (101) may check the value associated with the PA driving based on the calibrated value in operation 1007. The electronic device (101) may check, for example, the calibrated value corresponding to the checked target power by referring to information such as Table 1. If the value associated with the PA drive is not determined based on the calibrated value (operation 1005 - No), the electronic device (101) can determine the value associated with the PA drive based on the parameter associated with linearity in operation 1009.

[0173] FIG. 10b is a drawing for explaining an operation method of an electronic device according to one embodiment.

[0174] According to one embodiment, the electronic device (101) may, in operation 1021, verify at least one parameter for communication with a network. In operation 1023, the electronic device (101) may verify, for example, the antenna (340) and the PA (330) of FIG. 3A based on the verified at least one parameter. In operation 1025, the electronic device (101) may determine whether to verify a value associated with PA operation based on a calibrated value for the electronic device (101) based on the verified at least one parameter. Since the method of determining whether to verify a value associated with PA operation based on the calibrated value in operation 1025 has been described above with reference to FIG. 10A, the description thereof will not be repeated here. When a value associated with PA operation is confirmed based on the calibrated value (Operation 1025 - Yes), the electronic device (101) can, in operation 1027, confirm a value associated with PA operation based on the calibrated value. The electronic device (101) can, for example, confirm a calibrated value corresponding to the confirmed target power by referring to information such as Table 1. When a value associated with PA operation is not confirmed based on the calibrated value (Operation 1025 - No), the electronic device (101) can, in operation 1029, confirm whether to confirm a value associated with PA operation based on a parameter associated with linearity. When it is confirmed to confirm a value associated with PA operation based on a parameter associated with linearity (Operation 1029 - Yes), the electronic device (101) can, in operation 1031, confirm a value associated with PA operation based on a parameter associated with linearity. If it is not determined that a value associated with the PA drive is to be determined based on a parameter associated with linearity (Operation 1029 - No), the electronic device (101) may determine, in operation 1033, that a value associated with the PA drive is to be determined based on another stored value for at least one parameter identified.For example, the electronic device (101) can, by operating in the first mode, determine a value associated with PA operation based on a parameter associated with linearity. For example, the electronic device (101) can, by operating in a mode other than the first mode, determine a value associated with PA operation based on a value pre-stored corresponding to a parameter for communication. The pre-stored value corresponding to the parameter for communication may be different from, for example, a calibrated value, which will be described later.

[0175] FIG. 11A is a drawing for explaining an operation method of an electronic device according to one embodiment.

[0176] According to one embodiment, the electronic device (101) may, in operation 1101, verify at least one parameter for communication with a network. In operation 1103, the electronic device (101) may verify, for example, the antenna (340) and the PA (330) of FIG. 3A based on the verified at least one parameter. In operation 1105, the electronic device (101) may verify that the verification mode of the value associated with the PA operation is the first mode. For example, the first mode may be a mode for verifying the value associated with the PA operation based on a parameter associated with the linearity of the PA, and may be named an adaptive mode by adaptively adjusting the value associated with the PA operation, for example, as in FIG. 7A. The electronic device (101) may verify the mode corresponding to the parameter associated with the communication as the first mode by referring to information such as, for example, Table 2. For example, the electronic device (101) may determine the mode of verifying a value associated with PA driving as the first mode based on a parameter associated with the linearity of the PA. For example, the electronic device (101) may determine the mode of verifying a value associated with PA driving as the first mode based on satisfaction of a condition indicating that a margin corresponding to a parameter associated with PA linearity is relatively large. For example, the electronic device (101) may determine the mode corresponding to a parameter associated with communication based on a wired or wireless connection of the electronic device (101) of a hearing aid, which requires a reduction in transmission power, as the first mode, but this is exemplary and there is no limitation on the conditions for verifying the first mode. Based on the first mode being confirmed, the electronic device (101) can control the RF circuit (390) so that, in operation 1107, the first transmission signal is amplified by the confirmed PA (330) and provided to the confirmed antenna (340) as the confirmed PA operates based on the first value associated with the PA driving.The electronic device (101) can, in operation 1109, identify a parameter associated with the linearity of the identified PA based on a feedback value associated with the first transmission signal provided through the coupler (370) connected to the identified antenna. In operation 1111, the electronic device (101) can change a value associated with the PA operation from a first value to a second value according to a condition that a difference between the parameter associated with the linearity of the identified PA and a threshold value among a plurality of conditions is satisfied. In operation 1113, the electronic device (101) can control the RF circuit (390) so that the second transmission signal is amplified by the identified PA (330) and provided to the identified antenna (340) as the identified PA (330) operates based on the second value associated with the PA operation.

[0177] FIG. 11b is a drawing for explaining an operation method of an electronic device according to one embodiment.

[0178] According to one embodiment, the electronic device (101) may, in operation 1121, verify at least one parameter for communication with a network. In operation 1123, the electronic device (101) may verify, for example, the antenna (340) and the PA (340) as in FIG. 3A, based on the verified at least one parameter. In operation 1125, the electronic device (101) may verify that the verification mode of the value associated with the PA operation is the second mode. In the second mode, the electronic device (101) may set the value associated with the PA operation to a fixed value, and thus, the second mode may be referred to as a fixed mode. For example, the electronic device (101) may verify the second mode based on association information between the at least one parameter for communication with a network and the mode, as shown in Table 3.

[0179] Table 3

[0180]

[0181] For example, the electronic device (101) can determine the verification mode of the value associated with the PA driving as the second mode by referring to the related information as shown in Table 3 based on the fact that the current RAT is UTRA and the frequency band is 5. The electronic device (101) can set the maximum value of the driving voltage and / or ICQ of the PA (330) in operation 1127. For example, the electronic device (101) can confirm the value associated with the PA driving corresponding to the parameter for communication based on the related information as shown in Table 3. For example, the electronic device (101) can confirm the maximum driving voltage of 3580 and the maximum ICQ of 55 corresponding to UTRA and frequency band 5 by referring to the related information as shown in Table 3. Meanwhile, those skilled in the art will understand that in Table 3, parameters for other communication may be reflected alternatively and / or additionally to the RAT and the frequency band, and / or DSI may be reflected.

[0182] FIG. 11c is a drawing for explaining an operation method of an electronic device according to one embodiment.

[0183] According to one embodiment, the electronic device (101) may, in operation 1141, verify at least one parameter for communication with a network. In operation 1143, the electronic device (101) may verify, for example, the antenna (340) and the PA (340) as in FIG. 3A, based on the verified at least one parameter. In operation 1145, the electronic device (101) may verify that the verification mode of the value associated with the PA operation is the third mode. In the third mode, the electronic device (101) may set the RGI (or AGC) and / or IDX, which are indexes of the PA, and thus the third mode may be referred to as an index mode. For example, the electronic device (101) may verify the third mode based on association information between the at least one parameter for communication with a network and the mode, as shown in Table 4.

[0184] Table 4

[0185]

[0186] For example, the electronic device (101) can determine the verification mode of the value associated with the PA operation as the third mode by referring to the association information as shown in Table 4 based on the fact that the current RAT is E-UTRA and the frequency band is B5. The electronic device (101) can, in operation 1147, set the maximum value of the RGI and / or IDX of the PA (330). For example, the electronic device (101) can verify the value associated with the PA operation corresponding to the parameter for communication based on the association information as shown in Table 4. For example, the electronic device (101) can verify the maximum RGI of 45 corresponding to E-UTRA and the frequency band B5 by referring to the association information as shown in Table 4. Meanwhile, those skilled in the art will understand that in Table 4, parameters for other communications may be reflected alternatively and / or additionally to the RAT and the frequency band, and / or DSI may be reflected. The RGI may be set, for example, in the APT mode. IDX can be set, for example, in ET mode or APT and DPD modes, but there are no restrictions. For example, the lower the RGI value, the lower the PA's driving voltage can be. For example, the lower the IDX value, the lower the PA's driving voltage can be.

[0187] FIGS. 12A and 12B are drawings for explaining an operation method of an electronic device according to one embodiment.

[0188] According to one embodiment, the electronic device (101) may, in operation 1201, check at least one parameter for communication with a network. In operation 1203, the electronic device (101) may check whether the mode for checking the value associated with the PA operation is the first mode. Since the condition for checking whether it is the first mode has been described with reference to FIG. 11A, the description thereof will not be repeated here. Based on the fact that the mode for checking the value associated with the PA operation is the first mode (operation 1203 - Yes), in operation 1205, the electronic device (101) may check whether a value associated with the PA operation stored in advance exists. For example, the electronic device (101) may check whether the result of adjusting the value associated with the adaptive PA operation according to the first mode has been stored in advance, as described with reference to FIG. 7B. If it is determined that there is a value related to the pre-stored PA driving in the first mode (Operation 1205 - Yes), the electronic device (101) can, in operation 1207, set a value related to the PA driving based on the value related to the pre-stored PA driving in the first mode. If it is determined that there is no value related to the pre-stored PA driving in the first mode (Operation 1205 - No), the electronic device (101) can, in operation 1209, check a parameter related to linearity. For example, the electronic device (101) can check the parameter related to linearity based on a feedback signal, but this is exemplary. The electronic device (101) can, in operation 1211, check whether the margin checked based on the parameter related to linearity as the first condition exceeds N+2 dBm. If the margin exceeds N +2 dBm (operation 1211 - example), the electronic device (101) may, in operation 1213, adjust the value related to the PA drive according to the first tendency. For example, the electronic device (101) may increase the PA drive voltage, but there is no limitation.If the margin does not exceed N+2 dBm (Operation 1211 - No), the electronic device (101) can, in operation 1215, check whether the margin as the second condition is less than N dBm. Meanwhile, there is no limitation on the order of determining whether the first condition and the second condition are satisfied. If the margin is confirmed to be less than N dBm (Operation 1215 - Yes), the electronic device (101) can, in operation 1217, adjust a value related to PA driving according to the second tendency. For example, the electronic device (101) can reduce the PA driving voltage, but there is no limitation. If the margin is confirmed not to be less than N dBm (Operation 1215 - No), the electronic device (101) can maintain the value associated with the current PA driving. Although not shown, it will be appreciated by those skilled in the art that values ​​associated with optimal PA operation may be stored and utilized, for example, in operation 1205, as described with reference to FIGS. 7a and 7b.

[0189] The electronic device (101) can determine whether the verification mode of the value associated with the PA driving is the second mode in operation 1219 based on whether the verification mode of the value associated with the PA driving is not the first mode (operation 1203 - No). The conditions for determining whether the verification mode of the value associated with the PA driving is the second mode have been described with reference to FIG. 11B, and thus the description thereof will not be repeated here. If it is determined that the verification mode of the value associated with the PA driving is the second mode (operation 1219 - Yes), the electronic device (101) can set the maximum value of the driving voltage and / or ICQ of the PA in operation 1221 by referring to, for example, the link information such as Table 3.

[0190] If it is not determined that the verification mode of the value associated with the PA operation is the second mode (Operation 1219 - No), the electronic device (101) can, in operation 1223, determine whether the verification mode of the value associated with the PA operation is the third mode. The conditions for determining whether the verification mode of the value associated with the PA operation is the third mode have been described with reference to FIG. 11C, and therefore the description thereof will not be repeated here. If it is determined that the verification mode of the value associated with the PA operation is the third mode (Operation 1223 - Yes), the electronic device (101) can, in operation 1225, set the RGI and / or IDX of the PA to the stored values ​​by referring to the link information, for example, as in Table 4. In the embodiment of FIG. 12, it is illustrated as determining whether it is the first mode, determining whether it is the second mode, and then determining whether it is the third mode, but this is exemplary and there is no limitation on the verification order. If the verification mode of the value associated with the PA drive is not determined to be the third mode (operation 1223 - No), the electronic device (101) can set the value associated with the PA drive based on the calibrated value in operation 1227.

[0191] For example, the electronic device (101) can determine values ​​associated with mode and / or PA operation based on associated information such as Table 5.

[0192] Table 5

[0193]

[0194] As described with reference to FIGS. 11A to 11C, the electronic device (101) can identify values ​​associated with the mode and / or PA operation by referring to information such as Table 5. For example, the second mode can be applied when linearity is degraded in a specific bandwidth, RB, or frequency band, but there is no limitation. For example, the third mode can be applied for a specific DSI, but there is no limitation. For example, the first mode can be applied in a general environment excluding the second and third modes, but there is no limitation. Meanwhile, thresholds for margins may be set differently to 4 and 5, such as in the B41 band of E-UTRA and the N77 band of NR. Those skilled in the art will understand that information such as Table 5 may be stored in the electronic device (101), for example, by hard coding, or may be downloaded and stored in the electronic device (101), and there is no limitation on the storage method.

[0195] FIG. 13 is a drawing for explaining an operation method of an electronic device according to one embodiment.

[0196] According to one embodiment, the electronic device (101) may, in operation 1301, determine that the form factor of the electronic device (101) is the first form factor. For example, the electronic device (101) may be implemented to include a plurality of housings and a hinge connected between the plurality of housings. A display, at least part of which is flexible, may be disposed in the plurality of housings. For example, a portion of the display corresponding to the hinge may be flexible. Based on the rotation of the hinge, an angle formed by the plurality of housings may be changed, and the display may be folded or unfolded according to the angle between the plurality of housings, and thus the electronic device (101) may be referred to as a foldable device. The electronic device (101) may determine the folding or unfolding of the display as the first form factor, or may determine the angle between the housings as the first form factor. For example, the electronic device (101) may be implemented as a rollable device. In this case, the electronic device (101) may include a display that is at least partially flexible. A portion of the display may not be visually exposed in the first state because it is contained within the housing, and may be visually exposed in the second state according to the actuation of the driving device. When a portion of the display is contained within the housing in the first state, the flexible display may be bent. The electronic device (101) may identify the first state or the second state as the first form factor. Meanwhile, those skilled in the art will understand that there is no limitation on the above-described form factors and / or implementation forms of the electronic device (101).

[0197] The electronic device (101) can, in operation 1303, check at least one parameter for communication with a network. The electronic device (101), in operation 1305, can check a verification mode of a value associated with PA operation based on the first form factor and at least one parameter. The electronic device (101), in operation 1307, can check a value associated with PA operation based on the checked mode. For example, the electronic device (101) may set related information as shown in Table 5 for each form factor, but there is no limitation. For example, the electronic device (101) may, by referring to related information as shown in Table 5 corresponding to the first form factor, check a mode corresponding to a parameter for communication and / or a value associated with PA operation, but there is no limitation.
