Description

Electronic devices, Wi-Fi signal adjustment methods and devices Technical Field

[0001] This application belongs to the field of electronic technology, specifically relating to an electronic device, a method and apparatus for adjusting Wi-Fi signals. Background Technology

[0002] With the development of mobile communications, Wireless Fidelity (WiFi) technology has come into focus. Most mobile terminals now support WiFi for communication. To achieve higher WiFi signal output power, the power amplifier in the WiFi circuit of a mobile terminal typically operates near its saturation point. However, power amplifiers operating near saturation points produce nonlinear distortion, generating interference frequency components. For example, second-order nonlinear distortion produces second harmonics; third-order nonlinear distortion produces third harmonics, and so on. This nonlinear distortion degrades several antenna circuit performance indicators, such as error vector magnitude (EVM) and sidelobe suppression, affecting WiFi signal quality.

[0003] To address the nonlinear distortion problem in power amplifiers, Digital Pre-Distortion (DPD) calibration technology has been developed. This DPD technology can expand the linear range of a power amplifier without altering its characteristics, thus mitigating nonlinear distortion to some extent. Currently, mobile terminals typically perform DPD calibration when switching Wi-Fi on / off or switching Wi-Fi channels. For example, after detecting a switch from a closed to an open Wi-Fi connection, the mobile terminal performs DPD calibration to adjust the operating parameters of the Wi-Fi circuit based on the calibration parameters obtained, thereby adjusting the linear range of the power amplifier.

[0004] However, mobile terminals are typically held by the user. Whether the user holds the terminal or not significantly affects the load on the power amplifier's environment, and this load greatly influences the power amplifier's performance. This results in differences between DPD calibration results performed on a held Wi-Fi circuit and those performed on an unheld Wi-Fi circuit, thus affecting the accuracy of DPD calibration. Therefore, accurately adjusting the operating parameters of the Wi-Fi circuit becomes a crucial problem to solve. Summary of the Invention

[0005] The purpose of this application is to provide an electronic device, a method and apparatus for adjusting Wi-Fi signals, which can solve the problem that the accuracy of adjusting the working parameters of the current Wi-Fi circuit is poor due to the influence of changes in the holding state of the Wi-Fi circuit.

The environmental state includes a user-held state or an unheld state.

[0017] An adjustment module is used to adjust the operating parameters of the Wi-Fi circuit through digital predistortion (DPD) calibration when the environmental conditions of the Wi-Fi circuit change.

[0032] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0033] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0034] The electronic device, Wi-Fi signal adjustment method, and apparatus provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0035] Most mobile devices now support communication via WiFi technology. To achieve higher WiFi signal output power, the power amplifier in the WiFi circuitry of a mobile device typically operates near its saturation point.

[0036] However, mobile terminals are usually held by the user. Whether the user holds the terminal or not has a significant impact on the load of the power amplifier's environment, and the load of the power amplifier's environment has a significant impact on the power amplifier's performance when it is in operation.

[0037] For example, as shown in Table 1, when the Wi-Fi circuit's transmit power is 17 dBm, if the Wi-Fi circuit is not held, its EVM is -30, and the second harmonic signal magnitude is -55. If the Wi-Fi circuit is held vertically or horizontally by the user with one hand, its EVM is -26, and the second harmonic signal magnitude is -30. Similarly, when the Wi-Fi circuit's transmit power is 15 dBm, if the Wi-Fi circuit is not held, its EVM is -35, and the second harmonic signal magnitude is -50. If the Wi-Fi circuit is held vertically or horizontally by the user with one hand, its EVM is -30, and the second harmonic signal magnitude is -42. It is easy to see that the power amplifier's performance differs significantly before and after the user holds the Wi-Fi circuit. The mobile terminal can adjust the Wi-Fi circuit's operating parameters through DPD calibration to ensure the power amplifier's performance. Therefore, changes in the holding state of the Wi-Fi circuit can affect the accuracy of DPD calibration and the accuracy of adjusting the operating parameters of the Wi-Fi circuit. Thus, how to more accurately adjust the operating parameters of the Wi-Fi circuit to improve the performance of the power amplifier becomes a pressing issue.

[0039] Table 1

[0040] Please refer to Figure 1, which shows a schematic diagram of the structure of an electronic device provided in an embodiment of this application. As shown in Figure 1, the electronic device 100 includes: a radio frequency (RF) circuit 101 and a Wi-Fi circuit 102. The RF circuit 101 includes an RF transceiver 1011, a transmitting antenna 1012, and a receiving antenna 1013. The RF transceiver 1011 includes a transmitting port TX1, a receiving port RX1, and a detection port P. The detection port PDET is also known as a power detector (PDET) port. The transmitting antenna 1012 is connected to the transmitting port TX1, and the receiving antenna 1013 is connected to the receiving port RX1 and the detection port P through a switching assembly 1014.

[0041] When the switching assembly 1014 is in the first conducting state, the receiving antenna 1013 is connected to the receiving port RX1, and the electronic device transmits and receives signals through the radio frequency circuit 101 to perform radio frequency communication of the electronic device.

[0042] When the switch assembly 1014 is in the second conduction state, the receiving antenna 1013 is connected to the detection port P, and the electronic device obtains the harmonic signal of the WiFi circuit 102 through the receiving antenna 1013 and adjusts the operating parameters of the WiFi circuit 102 according to the harmonic signal.

[0043] The receiving antenna 1013 can receive signals that have a frequency harmonic relationship with the Wi-Fi signal transmitted by the Wi-Fi circuit 102, thereby receiving the harmonic signals of the Wi-Fi circuit 102. Optionally, the harmonic signal can be the second harmonic signal or the third harmonic signal of the Wi-Fi circuit, etc. For example, the harmonic signal is the second harmonic signal. The receiving antenna is used to receive signals in the N79 frequency band, and the Wi-Fi circuit is used to transmit 2.4GHz Wi-Fi signals; or, the receiving antenna is used to receive signals in the N78 frequency band, and the Wi-Fi circuit is used to transmit Wi-Fi signals in the B3 frequency band; or, the receiving antenna is used to receive signals in the N79 frequency band, and the Wi-Fi circuit is used to transmit Wi-Fi signals in the B40 frequency band.

[0044] In some embodiments of this application, the radio frequency transceiver 1011 can detect the target signal magnitude of the harmonic signal input through the detection port P, so that the electronic device can acquire the target signal magnitude of the harmonic signal and then execute the Wi-Fi signal adjustment method provided in the embodiments of this application to adjust the operating parameters of the Wi-Fi circuit 102 according to the target signal magnitude. For example, the electronic device adjusts the operating parameters of the Wi-Fi circuit through DPD calibration. The specific execution process of the Wi-Fi signal adjustment method provided in the embodiments of this application by the electronic device is described in detail below.

[0045] Since the RF transceiver 1011 typically has the function of detecting signal strength, a switching assembly connects the receiving antenna and the detection port, allowing the RF transceiver to receive harmonic signals from the Wi-Fi circuit via the receiving antenna and detect the target signal strength of the harmonic signals. By multiplexing the RF circuit and utilizing the switching assembly to multiplex the signal strength detection function of the RF transceiver, it is possible to achieve harmonic signal strength detection in electronic devices without having to set up separate circuit devices for detecting harmonic signals, thus reducing circuit redundancy.

[0046] In this embodiment, the electronic device includes a radio frequency (RF) circuit and a Wi-Fi circuit. The RF circuit includes an RF transceiver, a transmitting antenna, and a receiving antenna. The RF transceiver includes a transmitting port, a receiving port, and a detection port. The transmitting antenna is connected to the transmitting port, and the receiving antenna is connected to the receiving port and the detection port via a switching component. When the switching component is in a first conducting state, the receiving antenna is connected to the receiving port, and the electronic device transmits and receives signals through the RF circuit. When the switching component is in a second conducting state, the receiving antenna is connected to the detection port, and the electronic device acquires the harmonic signals of the Wi-Fi circuit through the receiving antenna and adjusts the operating parameters of the Wi-Fi circuit based on the harmonic signals. In this technical solution, the electronic device can acquire the harmonic signals of the Wi-Fi circuit through the receiving antenna of the RF circuit when the switching component is in the second conducting state, and adjust the operating parameters of the Wi-Fi circuit based on the harmonic signals. There is a correspondence between the harmonic signals, the transmitting power of the Wi-Fi circuit, and the user's holding state; there is also a correspondence between the harmonic signals, the transmitting power of the Wi-Fi circuit, and the unheld state. Therefore, the electronic device can determine the current environmental state of the Wi-Fi circuit based on the acquired harmonic signals, which includes the user's holding state or unheld state. Furthermore, when the environmental conditions of the Wi-Fi circuit change, the operating parameters of the Wi-Fi circuit are readjusted to ensure the accuracy of the adjustment.

[0047] Optionally, as shown in Figure 2, the switch assembly 1014 includes: a first switch element S1 and a second switch element S2. The stationary end of the first switch element S1 is connected to the detection port P. The first moving end of the first switch element S1 is connected to the first moving end of the second switch element S2. The second moving end of the first switch element S1 is connected to the transmitting antenna 1012. The stationary end of the second switch element S2 is connected to the receiving antenna 1013. The second moving end of the second switch element S2 is connected to the receiving port RX1. Optionally, the first switch element S1 and the second switch element S2 can be single-pole double-throw switches.

[0048] When the switching assembly 1014 is in the first conducting state, the stationary end of the second switching element S2 is connected to the second moving end of the second switching element S2, and the receiving port RX1 receives the signal through the receiving antenna 1013. Optionally, when the switching assembly 1014 is in the first conducting state, the second moving end of the first switching element S1 can also be connected to the stationary end of the first switching element S1, and the detection port P receives the transmitted signal from the transmitting antenna 1012 and detects the magnitude of the transmitted signal.

[0049] When the switch assembly 1014 is in the second conducting state, the stationary end of the second switch S2 is connected to the first moving end of the second switch S2, and the first moving end of the first switch S1 is connected to the stationary end of the first switch S1, connecting the detection port P and the receiving antenna 1013, and cutting off the receiving port RX1 and the receiving antenna 1013, so that the detection port P receives the harmonic signal of the WiFi circuit 102 through the receiving antenna 1013.

[0050] Further optionally, as shown in FIG2, the radio frequency circuit 101 further includes a first low-noise amplifier (LNA) 1015. The first low-noise amplifier 1015 is connected to the receiving antenna 1013 and the switching assembly 1014, respectively.

[0051] When the switching assembly 1014 is in the second conducting state, the receiving antenna 1013 is connected to the detection port P through the first low-noise power amplifier 1015. The electronic device acquires harmonic signals through the receiving antenna 1013 and adjusts the operating parameters of the Wi-Fi circuit according to the harmonic signals amplified by the first low-noise power amplifier 1015.

[0052] The first low-noise power amplifier 1015 amplifies the harmonic signal received by the receiving antenna 1013 to prevent the electronic device from being unable to acquire the harmonic signal due to its small size. Furthermore, since the RF transceiver 1011 can detect the target signal size of the harmonic signal, amplifying the harmonic signal by the first low-noise power amplifier 1015 also prevents the RF transceiver from having poor accuracy in detecting the harmonic signal size due to its small size.

[0053] For example, the stationary end of the second switch S2 is connected to the first low-noise power amplifier 1015, which is also connected to the receiving antenna 1013. When the switch assembly 1014 is in the second ON state, the stationary end of the second switch S2 is connected to the first moving end of the second switch S2, and the first moving end of the first switch S1 is connected to the stationary end of the first switch S1, so that the receiving antenna 1013 is connected to the detection port P through the first low-noise power amplifier 1015.

[0054] In this way, by adding a switching component to the high-frequency receiving path in the radio frequency circuit, that is, the radio frequency receiving path where the receiving antenna is located, and the power detection path where the detection port is located, the harmonic signal of the WiFi circuit, that is, the low-frequency transmission signal of the WiFi circuit, can be amplified by the first low-noise power amplifier and then switched to the detection port by the switching component, so that the radio frequency transceiver can accurately detect the magnitude of the harmonic signal transmitted by the WiFi circuit.

[0055] Optionally, as shown in Figure 3, the Wi-Fi circuit 102 includes: a wireless transceiver 1021, a third switch 1022, a second power amplifier (PA) 1023, and a Wi-Fi antenna 1024.

[0056] The wireless transceiver 1021 includes a wireless transmitting port TX2 and a wireless receiving port RX1. A Wi-Fi antenna 1024 is connected to the stationary terminal of a third switch 1022. The first moving terminal of the third switch 1022 is connected to the wireless transmitting port TX2 via a second power amplifier 1022. The second moving terminal of the third switch 1022 is connected to the wireless receiving port RX1.

[0057] When the switching assembly 1014 is in the second conducting state, the first moving end of the third switching element 1022 is connected to the stationary end, and the Wi-Fi antenna 1024 is connected to the wireless transmission port TX2 through the second power amplifier 1023. The wireless transceiver 1021 transmits the generated Wi-Fi signal to the second power amplifier 1023 through the wireless transmission port TX2. The Wi-Fi antenna 1024 transmits the Wi-Fi signal amplified by the second power amplifier 1023.

[0058] Optionally, when the switching component 1014 is not in the second conducting state, the electronic device can be in a Wi-Fi signal receiving state, and the second moving terminal of the third switching component 1022 can be connected to the stationary terminal, allowing the wireless transceiver 1021 to receive the Wi-Fi signal through the Wi-Fi antenna 1024. Further optionally, as shown in FIG4, the Wi-Fi circuit 102 also includes a third low-noise amplifier (LNA) 1025. The third low-noise amplifier 1025 is connected to both the second moving terminal of the third switching component 1022 and the wireless receiving port RX1. The electronic device can be in a Wi-Fi signal receiving state, and the Wi-Fi antenna 1024 transmits the received Wi-Fi signal to the third low-noise amplifier 1025. The wireless receiving port RX1 of the wireless transceiver 1021 receives the Wi-Fi signal amplified by the third low-noise amplifier 1025.

[0059] In some embodiments of this application, as shown in FIG4, the radio frequency circuit 101 further includes: a fourth power amplifier 1016, a coupler 1017, a first filter 1018, and a second filter 109.

[0060] The fourth power amplifier 1016 is connected to the transmit port TX1 of the RF transceiver 1011 and the coupler 1017. The fourth power amplifier 1016 amplifies the RF transmission signal transmitted by the RF transceiver 1011 through the transmit port TX1. The first filter 1018 is connected to the coupler 1017 and the transmit antenna 1012. The first filter 1018 filters the RF transmission signal transmitted from the fourth power amplifier 1016 to the first filter 1018, and transmits the filtered RF transmission signal using the transmit antenna 1012.

[0061] Coupler 1017 is also connected to detection port P via switch assembly 1014. Optionally, when switch assembly 1014 is in a first conducting state or a third conducting state, the stationary end and the second moving end of the first switch are connected, thereby connecting detection port P to the transmitting antenna. If the RF transceiver 1011 can detect the target signal magnitude of the harmonic signal by checking port P, when switch assembly 1014 is in the first conducting state or the third conducting state, the RF transceiver 1011 can detect the signal magnitude of the RF transmit signal output by the fourth power amplifier 1016. For example, as shown in FIG4, the RF circuit 101 further includes a resistor R. Coupler 1017 is also grounded via resistor R.

[0062] The second filter 109 is connected to both the receiving antenna 1013 and the first low-noise power amplifier 1015. The second filter 109 filters the signal received by the receiving antenna 1013 and transmits the filtered signal to the first low-noise power amplifier 1015. For example, the second filter 109 filters harmonic signals received by the receiving antenna 1013 and transmits the filtered harmonic signals to the first low-noise power amplifier 1015.

[0063] For example, assume the harmonic signal is a second harmonic signal. The receiving antenna is used to receive signals in the N79 band. The Wi-Fi circuit is used to transmit 2.4 GHz Wi-Fi signals. RF transceiver 1011 is a radio frequency IC (RFIC). Wireless transceiver 1021 is a WCN chip.

[0064] When the electronic device is in a Wi-Fi signal transmission state, in the Wi-Fi circuit 102, the first moving terminal of the third switch 1022 is connected to the stationary terminal, and the Wi-Fi antenna 1024 is connected to the wireless transmission port TX2 (Wi-Fi 2.4G TX) through the second power amplifier 1023. The wireless transceiver 1021 transmits the generated 2.4G Wi-Fi signal to the second power amplifier 1023 through the wireless transmission port TX2. The Wi-Fi antenna 1024 transmits the 2.4G Wi-Fi signal amplified by the second power amplifier 1023.

[0065] In the radio frequency circuit 101, the switching component 1014 is in a second conducting state. The stationary end of the second switching element S2 is connected to the first moving end of the second switching element S2, and the first moving end of the first switching element S1 is connected to the stationary end of the first switching element S1, connecting the detection port P and the receiving antenna 1013, and cutting off the receiving port RX1 (N79RX) and the receiving antenna 1013, so that the detection port P receives the harmonic signal of the WiFi circuit 102 through the receiving antenna 1013. The radio frequency transceiver 1011 detects the target signal magnitude of the harmonic signal input through the detection port P, so that the electronic device obtains the target signal magnitude of the harmonic signal, and then executes the WiFi signal adjustment method provided in this application embodiment to adjust the operating parameters of the WiFi circuit 102 according to the target signal magnitude.

[0066] When the electronic device is in a Wi-Fi signal receiving state, the second moving terminal of the third switch 1022 can be connected to the stationary terminal, and the Wi-Fi antenna 1024 transmits the received Wi-Fi signal to the third low-noise power amplifier 1025. The wireless receiving port RX1 (Wi-Fi 2.4G RX) of the wireless transceiver 1021 receives the Wi-Fi signal amplified by the third low-noise power amplifier 1025.

[0067] It should be noted that, due to the size limitations of electronic devices, in one optional scenario, the radio frequency circuit 101 and the Wi-Fi circuit 102 are laid out relatively close together.

[0068] In summary, the electronic device provided in this application includes a radio frequency (RF) circuit and a Wi-Fi circuit. The RF circuit includes an RF transceiver, a transmitting antenna, and a receiving antenna. The RF transceiver includes a transmitting port, a receiving port, and a detection port. The transmitting antenna is connected to the transmitting port, and the receiving antenna is connected to the receiving port and the detection port via a switching assembly. When the switching assembly is in a first conducting state, the receiving antenna is connected to the receiving port, and the electronic device transmits and receives signals through the RF circuit. When the switching assembly is in a second conducting state, the receiving antenna is connected to the detection port, and the electronic device acquires the harmonic signals of the Wi-Fi circuit through the receiving antenna and adjusts the operating parameters of the Wi-Fi circuit according to the harmonic signals. In this technical solution, the electronic device can acquire the harmonic signals of the Wi-Fi circuit through the receiving antenna of the RF circuit when the switching assembly is in the second conducting state, and adjust the operating parameters of the Wi-Fi circuit according to the harmonic signals. There is a correspondence between the harmonic signals, the transmitting power of the Wi-Fi circuit, and the user's holding state; there is also a correspondence between the harmonic signals, the transmitting power of the Wi-Fi circuit, and the unheld state. Therefore, electronic devices can determine the current environmental state of the Wi-Fi circuit based on the acquired harmonic signals. This environmental state includes whether the user is holding the device or not. Then, when the environmental state of the Wi-Fi circuit changes, the operating parameters of the Wi-Fi circuit are readjusted to ensure the accuracy of the parameter adjustments.

[0069] Please refer to Figure 5, which shows a flowchart of a Wi-Fi signal adjustment method provided in an embodiment of this application. The Wi-Fi signal adjustment method can be applied to the electronic device provided in this embodiment. Optionally, the Wi-Fi signal adjustment method can be applied to the electronic device shown in Figure 1 or Figure 4. In an optional implementation, the Wi-Fi signal adjustment method can be executed by a processor in the electronic device; the following example uses a processor executing the method. As shown in Figure 5, the Wi-Fi signal adjustment method includes:

[0070] Step 501: Obtain the target signal magnitude of the harmonic signal through the radio frequency transceiver, and obtain the current target transmission power and target correspondence of the WiFi circuit.

[0071] The target correspondence refers to the relationship between the Wi-Fi circuit's transmission power, environmental conditions, and the magnitude range of harmonic signals. Environmental conditions include whether the user is holding the device or not. The target correspondence records the magnitude range of harmonic signals radiated by the Wi-Fi circuit in the user-held state and the magnitude range of harmonic signals radiated in the unheld state, when the Wi-Fi circuit has multiple transmission power levels. Optionally, the target correspondence includes the correspondence between transmission power, user-held state, and the magnitude range of harmonic signals, as well as the correspondence between transmission power, unheld state, and the magnitude range of harmonic signals.

[0072] Optionally, the processor can acquire the target signal magnitude of the harmonic signal of the Wi-Fi circuit, as well as the current target transmission power and target correspondence of the Wi-Fi circuit, either in real time or periodically. The electronic device can store the target correspondence, allowing the processor to directly obtain it from the electronic device. Alternatively, the processor can obtain the target correspondence from a third-party device.

[0073] For example, when the processor is in the Wi-Fi signal transmission state, it can control the switching component in the radio frequency circuit to be in a second conduction state to obtain the target signal magnitude of the harmonic signal detected by the radio frequency transceiver. It can also obtain the target correspondence and, by acquiring the transmission parameters of the Wi-Fi circuit, obtain the current target transmission power of the Wi-Fi circuit, including the transmission parameters.

[0074] In some embodiments of this application, the target mapping relationship can be a mapping relationship directly generated by the processor. Alternatively, the target mapping relationship can also be a mapping relationship generated by a third-party device and transmitted to the electronic device. Optionally, the processor can generate the mapping relationship by executing a target mapping relationship generation process. The target mapping relationship generation process includes:

[0075] Step S1: Adjust the transmission power of the Wi-Fi circuit to multiple transmission powers in sequence.

[0076] Step S2: After each adjustment of the transmission power of the Wi-Fi circuit, the first signal magnitude of the harmonic signal radiated by the Wi-Fi circuit when the user holds the device, and the second signal magnitude of the harmonic signal radiated by the Wi-Fi circuit when the device is not held, are obtained through the radio frequency transceiver.

[0077] In one alternative implementation, after each adjustment of the Wi-Fi circuit's transmission power, the user can hold the Wi-Fi circuit, allowing the processor to obtain, via an RF transceiver, the first signal magnitude of the harmonic signal radiated by the Wi-Fi circuit while held by the user. Furthermore, after each adjustment of the Wi-Fi circuit's transmission power, the processor can also obtain, via an RF transceiver, the second signal magnitude of the harmonic signal radiated by the Wi-Fi circuit when it is not held.

[0078] In another alternative implementation, after each adjustment of the Wi-Fi circuit's transmission power, the user can hold the Wi-Fi circuit multiple times. This allows the processor to obtain, via the RF transceiver, the first signal magnitude of the harmonic signal radiated by the Wi-Fi circuit in the user-held state each time the user holds the circuit, thus obtaining multiple first signal magnitudes. Furthermore, after each adjustment of the Wi-Fi circuit's transmission power, the processor can obtain, via the RF transceiver, multiple second signal magnitudes of the harmonic signal radiated by the Wi-Fi circuit in the unheld state, thus obtaining multiple second signal magnitudes.

[0079] Step S3: Generate a size range corresponding to the user's holding state based on the first signal size, and generate a size range corresponding to the unheld state based on the second signal size.

[0080] In the first implementation of step S2, the process of the processor generating a size range corresponding to the user's holding state based on the first signal magnitude, and generating a size range corresponding to the unheld state based on the second signal magnitude, may include:

[0081] The processor determines the range from the difference between the first signal magnitude and the target value to the sum of the first signal magnitude and the target value as the size range corresponding to the user's holding state. It then determines the range from the difference between the second signal magnitude and the target value to the sum of the second signal magnitude and the target value as the size range corresponding to the unheld state.

[0082] In the latter implementation of step S2, the process of the processor generating a size range corresponding to the user's holding state based on the first signal magnitude, and generating a size range corresponding to the unheld state based on the second signal magnitude, may include:

[0083] The processor determines the value range of multiple first signal magnitudes as the size range corresponding to the user's holding state. It also determines the value range of multiple second signal magnitudes as the size range corresponding to the unheld state.

[0084] Step S4: Generate target correspondence based on the size range corresponding to the user holding state and the size range corresponding to the unheld state under each transmission power.

[0085] For example, the generated target correspondence can be as follows: Transmission power: W1, environmental state: Wi-Fi circuit is not held, magnitude range of 2nd harmonic signal: A1±1 and C1±1 correspond; Transmission power: W1, environmental state: Wi-Fi circuit is held by user, magnitude range of 2nd harmonic signal: B1±1 and D1±1 correspond; Transmission power: W2, environmental state: Wi-Fi circuit is not held, magnitude range of 2nd harmonic signal: A2±1 and C2±1 correspond; Transmission power: W2, environmental state: Wi-Fi circuit is held by user, magnitude range of 2nd harmonic signal: B2±1 and D2±1 correspond.

[0086] Step 502: Determine the environmental state of the Wi-Fi circuit that corresponds to both the target's transmission power and the target's signal strength based on the target correspondence.

[0087] Optionally, the processor can look up the environmental state corresponding to both the target's transmission power and the target's signal strength from the target correspondence to obtain the current environmental state of the Wi-Fi circuit.

[0088] For example, after the processor obtains the target signal magnitude K of the harmonic signal through the RF transceiver, it obtains the target correspondence and reads the transmission power parameters of the Wi-Fi circuit to obtain the target transmission power W1. The target correspondence includes: Transmission power: W1, environmental state: Wi-Fi circuit is in an unheld state, magnitude range of the 2nd harmonic signal: A1±1 and C1±1 correspond; Transmission power: W1, environmental state: Wi-Fi circuit is in a user-held state, magnitude range of the 2nd harmonic signal: B1±1 and D1±1 correspond; Transmission power: W2, environmental state: Wi-Fi circuit is in an unheld state, magnitude range of the 2nd harmonic signal: A2±1 and C2±1 correspond; Transmission power: W2, environmental state: Wi-Fi circuit is in a user-held state, magnitude range of the 2nd harmonic signal: B2±1 and D2±1 correspond.

[0089] If A1 < K < A1+1, the processor determines that the current environmental state of the Wi-Fi circuit is unheld. If B1 < K < B1+1, the processor determines that the current environmental state of the Wi-Fi circuit is held by the user.

[0090] Step 503: When the environmental conditions of the Wi-Fi circuit change, adjust the operating parameters of the Wi-Fi circuit through DPD calibration.

[0091] In this embodiment, when the environmental conditions of the Wi-Fi circuit change, the processor can re-execute DPD calibration to adjust the operating parameters of the Wi-Fi circuit. This allows DPD calibration to be performed before and after the user holds the Wi-Fi circuit, ensuring that DPD calibration is triggered promptly when factors affecting the power amplifier's performance change, adjusting the Wi-Fi circuit's operating parameters, maintaining excellent power amplifier performance, and thus improving the transmission quality of the Wi-Fi signal and enhancing the user experience.

[0092] In this embodiment, the target signal magnitude of the harmonic signal is obtained through a radio frequency transceiver, as well as the current target transmission power and target correspondence of the Wi-Fi circuit. Based on the target correspondence, the environmental state of the Wi-Fi circuit corresponding to both the target transmission power and the target signal magnitude is determined. Furthermore, if the environmental state of the Wi-Fi circuit changes, the operating parameters of the Wi-Fi circuit are readjusted through DPD calibration to ensure the accuracy of the adjustment.

[0093] Due to the size limitations of electronic devices, the radio frequency (RF) circuit and Wi-Fi circuit are typically positioned relatively close together. This means that when a user holds the Wi-Fi circuit, they may also be holding the RF circuit, which in turn affects the first low-noise power amplifier within the RF circuit.

[0094] Based on this, the target correspondence can record the magnitude range of harmonic signals radiated by the Wi-Fi circuit when both the Wi-Fi circuit and the radio frequency circuit are held by the user, with the Wi-Fi circuit having multiple transmission powers in sequence; the magnitude range of harmonic signals radiated by the Wi-Fi circuit when it is not held, and the radio frequency circuit is held by the user; the magnitude range of harmonic signals radiated by the Wi-Fi circuit when both the Wi-Fi circuit and the radio frequency circuit are not held; and the magnitude range of harmonic signals radiated by the Wi-Fi circuit when it is held by the user, and the radio frequency circuit is not held.

[0095] For example, the target correspondence is recorded in the form of a correspondence table as shown in Table 2 below. As shown in Table 2, the target correspondence includes:

[0096] Transmit power: 17dBm; Environmental conditions: Wi-Fi circuit is unhandled + power detection circuit is unhandled; Magnitude range of 2nd harmonic signal: A1±1;

[0097] Transmit power: 17dBm; Environmental conditions: Wi-Fi circuit is held by the user + power detection circuit is not held; Magnitude range of 2nd harmonic signal: B1±1;

[0098] Transmit power: 17dBm; Environmental conditions: Wi-Fi circuit is in an unheld state + power detection circuit is in a user-held state; Magnitude range of the second harmonic signal: C1±1;

[0099] Transmit power: 17dBm; Environmental conditions: Wi-Fi circuit is held by the user + power detection circuit is held by the user; Magnitude range of the second harmonic signal: D1±1.

[0103] Similarly, after acquiring the target signal magnitude of the harmonic signal through the RF transceiver and the current target transmission power and target correspondence of the Wi-Fi circuit, the processor also determines the environmental state of the Wi-Fi circuit corresponding to both the target transmission power and the target signal magnitude based on the target correspondence. Then, if the environmental state of the Wi-Fi circuit changes, the processor readjusts the operating parameters of the Wi-Fi circuit through DPD calibration to ensure the accuracy of the adjustment.

[0104] In summary, the Wi-Fi signal adjustment method provided in this application obtains the target signal magnitude of the harmonic signal through a radio frequency transceiver, and obtains the current target transmission power and target correspondence of the Wi-Fi circuit. Based on the target correspondence, it determines the environmental state of the Wi-Fi circuit corresponding to both the target transmission power and the target signal magnitude.
