Description

Technical Field

[0001] This application relates to the field of antenna technology, and in particular to an antenna decoupling method, decoupling device and electronic device. Background Technology

[0002] Electronic devices can use Radio Access Technology (RAT) for wireless communication, and each RAT relies on its matching antenna to achieve its corresponding function. In some scenarios, electronic devices need to use two RATs simultaneously. For example, they might use Wireless Fidelity (Wi-Fi) for data transmission and simultaneously use Bluetooth (BT) for data transmission, or they might use Wi-Fi for data transmission and simultaneously use a cellular network to maintain voice service. In these scenarios, the electronic device may need to use two different independent antennas for the two different RATs.

[0003] To avoid mutual interference between the two antennas, a certain degree of isolation is required. However, with the development of electronic devices in modern industrial design, the screen-to-body ratio of electronic devices is gradually increasing and the bezels are gradually narrowing. As a result, the spatial layout of electronic devices is becoming more compact, and current methods for reducing isolation (such as the resonant unit loading method, defect ground method, and mode orthogonal method) cannot achieve the required high degree of isolation.

[0004] Therefore, it is currently impossible to achieve both a compact layout between antennas and high isolation decoupling in electronic devices. Summary of the Invention

[0005] This application provides an antenna decoupling method, decoupling device, and electronic device, which can improve the isolation between antennas and achieve antenna decoupling within the compact spatial layout of electronic devices.

[0006] In a first aspect, embodiments of this application provide an antenna decoupling method applied to an electronic device, comprising: acquiring a first antenna pattern corresponding to a first antenna and a second antenna pattern corresponding to a target antenna, wherein the first antenna and the target antenna are used to form an array antenna, the array antenna being used to transmit and receive radio frequency signals of a first radio access technology (RAT) in the electronic device; acquiring the azimuth of the first antenna corresponding to the second antenna, the second antenna being used to transmit and receive radio frequency signals of a second RAT in the electronic device, the second RAT being different from the first RAT; generating a target antenna pattern based on the first antenna pattern and the second antenna pattern, wherein the notch direction corresponding to the target antenna pattern is opposite to the azimuth of the first antenna, so as to decouple the first antenna from the second antenna.

[0007] The antenna decoupling method provided in this application adjusts the antenna pattern in the electronic device based on the analog beamforming method, so that the target antenna pattern corresponding to the array antenna points to the first antenna azimuth corresponding to the second antenna. In this way, within the compact spatial layout of the electronic device, the antenna isolation between the array antenna transmitting and receiving the radio frequency signal of the first RAT and the second antenna transmitting and receiving the radio frequency signal of the second RAT is greatly improved, thereby achieving antenna decoupling.

[0046] 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. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the protection scope of this application.

[0047] In the description of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. The "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "multiple" means two or more. The terms "first," "second," etc., do not limit the quantity or order of execution, and "first," "second," etc., do not necessarily imply differences.

[0048] It should be noted that, in this application, the terms "exemplary" or "for example" are used to indicate that something is being described as an example, illustration, or illustration. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0049] To ensure clarity and conciseness in the description of the following embodiments, a brief introduction to the relevant concepts or technologies is given first:

[0050] Isolation refers to the degree of mutual interference between two or more antennas in an antenna system. Antenna isolation is usually measured in decibels (dB) and represents the relative difference in power level between one signal and another. Its value affects the performance and stability of the antenna system. Higher antenna isolation indicates less mutual interference between antennas, resulting in better signal transmission or reception performance. Lower antenna isolation may lead to signal cross-coupling, increased interference, and degraded system performance.

[0051] Antenna clearance refers to the unobstructed space around an antenna, that is, the area around the antenna that is not blocked or interfered with by other objects. Antenna clearance is very important in the installation and deployment of antennas to ensure the normal operation of the antenna and good signal transmission.

[0052] An antenna radiation pattern is a graphical representation of an antenna's radiation pattern. This graph can be drawn in polar or Cartesian coordinate systems and can be used to display the antenna's radiated power or receiver sensitivity along different directions in space. The antenna radiation pattern can display the main lobe and side lobes. The main lobe represents the direction in which the antenna primarily radiates energy, while the side lobes represent the energy distribution in other directions. The presence of side lobes may cause the antenna to radiate power in non-main lobe directions, potentially interfering with wireless communication.

[0053] Antenna coupling refers to the phenomenon of mutual influence or interference between two or more antennas in an antenna system. Antenna coupling can generally be divided into electromagnetic coupling and physical coupling. Electromagnetic coupling refers to the phenomenon of antennas influencing each other through electromagnetic fields. When two or more antennas are arranged in parallel or crossed positions within a certain distance, they will radiate, receive, or transmit electromagnetic waves to each other, resulting in mutual interference. This interference can lead to problems such as degraded signal quality and increased bit error rate. Physical coupling refers to the mutual influence between antennas through contact or mutual support between structural objects. For example, in some antenna systems, antennas may be physically connected through shared supports or common bases. This connection method may lead to problems such as vibration and mechanical resonance, thereby affecting system performance.

[0054] Antenna decoupling refers to measures taken to reduce or eliminate coupling effects in an antenna system, ensuring that each antenna operates independently and avoiding mutual interference. Antenna decoupling improves system performance and stability, ensuring reliable signal transmission and reception.

[0055] Antenna nulling is a characteristic designed into the antenna pattern that significantly reduces the ability to receive or transmit signals in a specific direction, forming a "notch" or "concave".

[0056] The application scenarios of the embodiments of this application will be described below.

[0057] Electronic devices can perform a variety of wireless communication functions. For example, they can perform wireless communication in mobile communication scenarios such as voice calls, text messaging, and data transmission. They can also perform wireless communication in Internet scenarios such as browsing web pages, using applications, and sending and receiving emails through wireless Fidelity (Wi-Fi), Bluetooth, and other wireless communication technologies. Furthermore, they can perform wireless communication in IoT scenarios such as controlling smart homes.

[0058] To achieve different wireless communication functions, electronic devices need to support multiple wireless communication standards, such as cellular communication, Wi-Fi communication, Bluetooth communication, Global Navigation Satellite System (GNSS) communication, satellite communication, Ultra-Wideband (UWB) communication, and Near Field Communication (NFC) communication. Under these specific wireless communication standards, electronic devices can apply specific Radio Access Technology (RAT), and each RAT relies on its matching antenna to achieve its corresponding function. Therefore, electronic devices have a relatively large number of antennas.

[0059] With the development of electronic devices in modern industrial design, screen-to-body ratios are gradually increasing and bezels are becoming narrower. This significantly reduces the antenna clearance, creating a conflict between the number of antennas and the available clearance. Consequently, electronic devices often feature compact antenna layouts and poor isolation between antennas. While most antennas have low isolation requirements, with below 20dB being sufficient, a minority require higher isolation. Poor isolation makes it difficult to meet user needs.

[0060] Taking Bluetooth antennas and Wi-Fi antennas as examples, the operating frequency band of Bluetooth antennas is 2400MHz to 2483MHz, while the 2.4GHz Wi-Fi antenna operates in the same operating frequency band as the Bluetooth antenna.

[0061] Generally, Bluetooth and Wi-Fi antennas can share the same antenna. To ensure isolation between these two types of antennas, this shared antenna operates in a time-division multiplexing (TDM) manner, hence the name time-division multiplexed antenna. TDM is a technique in communication that interleaves multiple signals across different time segments on a time axis. Each signal can be allocated a fixed time segment during transmission, allowing multiple signals to be transmitted alternately on the same transmission medium, thus achieving multiplexing of signals. In some cases, time-division multiplexed antennas for Bluetooth and Wi-Fi cannot meet user needs.

[0062] Figure 1 This is a schematic diagram of the working scenario of a time-division multiplexing antenna.

[0063] like Figure 1 As shown, when a time-division multiplexed antenna transmits high-bitrate audio files (e.g., audio in Free Lossless Audio Codec (FLAC) format or Low Latency High Definition Audio Codec (LHDAC) format) via Bluetooth, the Bluetooth radio frequency signal has a high duty cycle on the time-division multiplexed antenna, causing Wi-Fi to maintain only a 1-transmit-1-receive (1T1R) capability. This limits Wi-Fi's transmit and receive capabilities on the time-division multiplexed antenna, making it prone to stuttering and negatively impacting the user experience.

[0064] Electronic devices can use two separate antennas for Bluetooth and 2.4GHz Wi-Fi to avoid Wi-Fi lag. However, the antenna isolation between these two separate antennas needs to be maintained at more than 30dB to prevent them from interfering with each other.

[0065] In other words, there is a high degree of isolation required between Wi-Fi antennas and Bluetooth antennas. However, in the compact space layout of electronic devices, the antenna isolation between these two independent antennas cannot reach more than 30dB.

[0066] Therefore, it is currently impossible to achieve both a compact layout between antennas and high isolation decoupling in electronic devices.

[0067] To address this issue, embodiments of this application provide an antenna decoupling method.

[0068] The antenna decoupling method provided in this application can be applied to electronic devices. These electronic devices include, but are not limited to, mobile phones, tablets, personal computers, workstations, large-screen devices (e.g., smart screens, smart TVs), wearable devices (e.g., smart bracelets, smartwatches), handheld game consoles, home game consoles, virtual reality devices, augmented reality devices, mixed reality devices, and in-vehicle smart terminals.

[0069] Figure 2 This is a schematic diagram of the hardware structure of the electronic device provided in the embodiments of this application.

These different processing units may be independent devices or integrated into one or more processors.

[0072] An application processor (AP) is used to handle general computing tasks of electronic devices, including running applications, processing graphics and multimedia content, and managing user interfaces.

[0073] A modem is used to handle the modulation and demodulation of wireless signals, as well as the encryption and decryption of data in wireless communication protocols.

[0074] The baseband processor is the digital part of the modem, responsible for the digital processing of wireless signals. It can perform tasks such as channel coding, decoding, signal processing, forward error correction, and manage the physical layer and data link layer of the wireless communication protocol.

[0075] The memory 120 can be used to store computer executable program code, including instructions. The memory 120 may include a program storage area and a data storage area.

It can also be used to connect headphones for audio playback. This interface can also be used to connect other electronic devices, such as AR devices.

[0077] It is understood that the interface connection relationships between the modules illustrated in the embodiments of this application are merely illustrative and do not constitute a structural limitation on the electronic device 100. In other embodiments of this application, the electronic device 100 may also employ different interface connection methods or combinations of multiple interface connection methods as described in the above embodiments.

[0078] The charging management module 140 receives charging input from a charger. The charger can be a wireless charger or a wired charger. In some wired charging embodiments, the charging management module 140 receives charging input from the wired charger via the USB interface 130. In some wireless charging embodiments, the charging management module 140 receives wireless charging input via the wireless charging coil of the electronic device 100.

In some other embodiments, the antennas can be used in conjunction with tuning switches.

[0082] The mobile communication module 150 can provide solutions for wireless communication, including 2G / 3G / 4G / 5G, applied to the electronic device 100. The mobile communication module 150 may include at least one filter, switch, power amplifier (PA), low-noise amplifier (LNA), etc. The mobile communication module 150 can receive electromagnetic waves via antenna 1, and perform filtering, amplification, and other processing on the received electromagnetic waves before transmitting them to a modem processor for demodulation.

In some embodiments, at least some functional modules of the mobile communication module 150 and at least some modules of the processor 110 may be housed in the same device.

[0083] The modem may include a modulator and a demodulator. The modulator modulates the low-frequency baseband signal to be transmitted into a mid-to-high frequency signal. The demodulator demodulates the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then transmits the demodulated low-frequency baseband signal to a baseband processor for processing. After processing by the baseband processor, the low-frequency baseband signal is transmitted to an application processor. The application processor outputs sound signals through an audio device (not limited to speaker 170A, receiver 170B, etc.) or displays images or videos through a display screen 193. In some embodiments, the modem may be a standalone device. In other embodiments, the modem may be independent of the processor 110 and housed within the same device as the mobile communication module 150 or other functional modules.

[0084] The wireless communication module 160 can provide solutions for wireless communication applications on the electronic device 100, including Wireless Local Area Networks (WLAN) (such as Wireless Fidelity (Wi-Fi) networks), Bluetooth (BT), Global Navigation Satellite System (GNSS), Frequency Modulation (FM), Near Field Communication (NFC), and Infrared (IR) technologies.

[0086] Electronic device 100 implements display functions through a GPU, a display screen 193, and an application processor. The GPU is a microprocessor for image processing, connected to the display screen 193 and the application processor. The GPU is used to perform mathematical and geometric calculations and for graphics rendering. Processor 110 may include one or more GPUs, which execute program instructions to generate or modify display information.

[0087] Display screen 193 is used to display images, videos, etc. Display screen 193 includes a display panel. The display panel can be a liquid crystal display (LCD). The display panel can also be manufactured using organic light-emitting diodes (OLEDs), active-matrix organic light-emitting diodes (AMOLEDs), flexible light-emitting diodes (FLEDs), minimized, microled, micro-oled, quantum dot light-emitting diodes (QLEDs), etc. In some embodiments, the electronic device may include one or N displays 193, where N is a positive integer greater than 1.

[0088] Electronic device 100 can perform shooting functions through ISP, camera 192, video codec, GPU, display 193 and application processor.

[0089] The ISP (Image Signal Processor) is used to process data fed back from the camera 192. For example, when taking a picture, the shutter is opened, and light is transmitted through the lens to the camera's photosensitive element. The light signal is converted into an electrical signal, and the camera's photosensitive element transmits the electrical signal to the ISP for processing, transforming it into an image visible to the naked eye. The ISP can also perform algorithmic optimization of image noise, brightness, and skin tone. The ISP can also optimize parameters such as exposure and color temperature of the shooting scene. In some embodiments, the ISP can be set within the camera 192.

[0090] Camera 192 is used to capture still images or videos. An object passes through the lens to generate an optical image that is projected onto a photosensitive element. The photosensitive element converts the light signal into an electrical signal, which is then passed to an ISP (Internet Service Provider) for conversion into a digital image signal. The ISP outputs the digital image signal to a DSP (Digital Signal Processor) for processing.

The touch sensor 180A and display screen 193 together form a touchscreen, also known as a "touchscreen." Touch sensor 180A is used to detect touch operations applied to or near it. The touch sensor can transmit the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through display screen 193. In other embodiments, touch sensor 180A may also be disposed on the surface of electronic device 100, in a different location than display screen 193.

[0093] The gyroscope sensor 180B can be used to determine the motion attitude of the electronic device 100. In some embodiments, the gyroscope sensor 180B can determine the angular velocity of the electronic device 100 about three axes (i.e., the x, y, and z axes). The gyroscope sensor 180B can be used for image stabilization. For example, when the shutter is pressed, the gyroscope sensor 180B detects the angle of the shake of the electronic device 100, calculates the distance that the lens module needs to compensate based on the angle, and allows the lens to counteract the shake of the electronic device 100 by moving in the opposite direction, thus achieving image stabilization. The gyroscope sensor 180B can also be used in navigation and motion-sensing game scenarios.

[0094] The 180C barometric pressure sensor is used to measure barometric pressure.

[0095] The geomagnetic sensor 180D includes a Hall sensor. The electronic device 100 can use the geomagnetic sensor 180D to detect the opening and closing of the flip cover.

[0096] The 180E accelerometer can detect the magnitude of acceleration of electronic device 100 in various directions (typically three axes). When electronic device 100 is stationary, it can detect the magnitude and direction of gravity. It can also be used to identify the posture of electronic devices and applied to applications such as screen orientation switching and pedometers.

[0097] Distance sensor 180F is used to measure distance. Electronic device 100 can measure distance via infrared or laser.

[0098] The proximity sensor 180G may include, for example, a light-emitting diode (LED) and a light detector, such as a photodiode. The LED may be an infrared LED. The electronic device 100 emits infrared light outward through the LED. The electronic device 100 uses a photodiode to detect infrared reflected light from nearby objects.

[0099] The fingerprint sensor 180H is used to collect fingerprints. The electronic device 100 can utilize the characteristics of the collected fingerprints to achieve fingerprint unlocking, accessing application locks, taking photos with fingerprints, answering calls with fingerprints, etc.

[0100] The 180J temperature sensor is used to detect temperature.

[0101] Buttons 190 include a power button, volume buttons, etc. Buttons 190 can be mechanical buttons or touch-sensitive buttons. Electronic device 100 can receive button input and generate key signal inputs related to user settings and function control of electronic device 100.

[0102] Motor 191 can generate vibration alerts.

[0103] The SIM card interface 194 is used to connect a SIM card. The SIM card can be inserted into or removed from the SIM card interface 194 to make contact with and separate from the electronic device 100. The electronic device 100 can support one or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 194 can support Nano SIM cards, Micro SIM cards, SIM cards, etc. Multiple cards can be inserted into the same SIM card interface 194 simultaneously. The multiple cards can be of the same or different types. The SIM card interface 194 is also compatible with different types of SIM cards. The SIM card interface 194 is also compatible with external memory cards. The electronic device 100 interacts with the network through the SIM card to realize functions such as calls and data communication. In some embodiments, the electronic device 100 uses an eSIM, i.e., an embedded SIM card. The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100.

[0104] The software system of electronic device 100 can adopt a layered architecture, event-driven architecture, microkernel architecture, microservice architecture, or cloud architecture. This application embodiment uses the layered architecture Android system as an example to exemplify the software structure of electronic device 100.

[0105] Figure 3 This is a schematic diagram of the software structure of the electronic device provided in the embodiments of this application.

[0106] A layered architecture divides software into several layers, each with a clear role and function. Layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom: the application layer, the application framework layer, the Android runtime and system libraries, and the kernel layer.

[0107] The application layer can include a series of application packages.

[0108] like Figure 3 As shown, the application package may include applications such as battery management, camera, gallery, calendar, call, map, navigation, music, video, and SMS.

[0109] The application framework layer provides an Application Programming Interface (API) and programming framework for applications in the application layer. The application framework layer includes some predefined functions.

[0110] like Figure 3 As shown, the application framework layer may include a window manager, an input manager, a sensor manager, a phone manager, a resource manager, a notification manager, etc.

[0111] The input manager can be used to listen for user input events, such as clicks and swipes performed by the user's finger on the display screen 193 of the electronic device 100. By listening to input events, the electronic device 100 can determine whether it is in use.

[0112] In this embodiment of the application, by listening to input events, the electronic device 100 can determine whether the user needs to apply RAT.

[0113] The sensor manager is used to monitor data returned by various sensors in electronic devices, such as motion sensor data, proximity sensor data, and temperature sensor data. Using the data returned by these sensors, the electronic device can determine if it is experiencing vibrations or if the display screen is obstructed.

[0114] The Android Runtime consists of core libraries and a virtual machine. The Android runtime is responsible for the scheduling and management of the Android system.

[0115] The core library consists of two parts: one part is the functionalities that need to be called by the Java language, and the other part is the Android core library.

[0116] The application layer and application framework layer run in a virtual machine. The virtual machine executes the Java files of the application layer and application framework layer as binary files. The virtual machine is used to perform functions such as object lifecycle management, stack management, thread management, security and exception management, and garbage collection.

[0117] System libraries can include multiple functional modules. For example: Surface Manager, Media Libraries, 3D graphics processing libraries (e.g., OpenGL ES), 2D graphics engines (e.g., SGL), etc.

[0118] The Surface Manager is used to manage the display subsystem and provides the blending of 2D and 3D layers for multiple applications.

[0119] The media library supports playback and recording of various common audio and video formats, as well as still image files. It supports multiple audio and video encoding formats, such as MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG.

[0120] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, compositing, and layer processing.

[0121] A 2D graphics engine is a graphics engine for 2D drawing.

[0122] The kernel layer is the layer between hardware and software. The kernel layer contains at least the display driver, camera driver, audio driver, and sensor driver.

[0123] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the electronic device 100. In other embodiments of this application, the electronic device 100 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0124] Figure 4 This is a schematic diagram illustrating a usage scenario of the antenna decoupling method provided in the embodiments of this application.

[0125] like Figure 4 As shown in area A, in one implementation, electronic device 100 can access a wireless local area network (WLAN) through a first antenna 101, which can be a Wi-Fi antenna. Simultaneously, electronic device 100 can also perform Bluetooth transmission through a second antenna 102 in area B, which can be a Bluetooth antenna. When electronic device 100 is not in decoupling mode, the first antenna pattern corresponding to the first antenna 101 is shown in area A1, and the third antenna pattern corresponding to the second antenna 102 is shown in area B1. The sidelobes of the first antenna pattern corresponding to the first antenna 101 are opposite to the sidelobes of the third antenna pattern corresponding to the second antenna 102, resulting in poor isolation between the first antenna 101 and the second antenna 102. This leads to near-field coupling between the first antenna 101 and the second antenna 102, failing to meet the requirements for concurrent Wi-Fi and Bluetooth operation.

[0126] like Figure 4 As shown in B, when the electronic device 100 enters the decoupling mode, the first antenna 101 and the target antenna 103 form an array antenna. The radiation pattern of the target antenna corresponding to the array antenna is shown in region C1. In this way, the notch direction of the target antenna radiation pattern corresponding to the array antenna points to the azimuth of the first antenna corresponding to the second antenna 102. The isolation between the array antenna and the second antenna 102 is greatly improved, and the first antenna 101 and the second antenna 102 are decoupled.

[0127] It should be noted that the RAT in the electronic device includes at least one of GSM, GPRS, CDMA, WCDMA, TD-SCDMA, LTE, BT, GNSS, WLAN, NFC, and FM. In this embodiment, the first antenna 101 transmits and receives radio frequency signals of the first RAT in the electronic device 100, and the second antenna 102 transmits and receives radio frequency signals of the second RAT in the electronic device 100. The first RAT and the second RAT can be any of the above-mentioned RATs, as long as they are different. This embodiment does not limit the types of the first RAT and the second RAT. This embodiment only uses Wi-Fi technology as the first RAT and Bluetooth technology as the second RAT for illustrative purposes.

[0128] The implementation of the embodiments of this application will be described in detail below.

[0129] Figure 5 This is the first flowchart of the antenna decoupling method provided in the embodiments of this application.

[0130] Figure 6 This is an interactive schematic diagram of the antenna decoupling method provided in the embodiments of this application.

[0131] like Figure 5 and Figure 6 As shown, in some embodiments, the method includes the following steps S101-S105.

[0132] In step S101, the electronic device 100 acquires at least one target information.

[0133] In one implementation, the target information includes at least one of the following: the target RAT's operating status information, operating frequency band information, operating radio frequency path information, and antenna information.

[0134] In this way, the electronic device 100 can obtain the working information of the RAT in the current scenario, so as to monitor whether there are two RATs transmitting and receiving radio frequency signals at the same time, and then implement the technical solution shown in this application in the scenario where two RATs transmit and receive radio frequency signals at the same time.

[0135] The following explanation addresses the case where the target RAT includes a first RAT and a second RAT. The first RAT is different from the second RAT.

[0136] The electronic device 100 can acquire first RAT information and second RAT information. Specifically, the electronic device 100 can acquire first RAT information and second RAT information based on the operating status information corresponding to the target RAT. The first RAT information is used to record the electronic device 100's transmission and reception of radio frequency signals for the first RAT, and the second RAT information is used to record the electronic device 100's transmission and reception of radio frequency signals for the second RAT.

[0137] For example, when electronic device 100 simultaneously transmits and receives radio frequency signals corresponding to Wi-Fi and Bluetooth, electronic device 100 can monitor the working status of Wi-Fi and Bluetooth to determine that the first RAT information is Wi-Fi and the second RAT information is Bluetooth.

[0138] Specifically, the electronic device 100 can obtain the working status of Wi-Fi and Bluetooth by monitoring at least one of system settings, notification bar, device manager, command-line tools, and system logs. For example, in response to an operation to turn on the Wi-Fi switch in the settings application, the electronic device 100 can determine that Wi-Fi is on. If Wi-Fi is on, the electronic device 100 can obtain the log entries of the Wi-Fi module in the system log to determine whether Wi-Fi is working.

[0139] Correspondingly, in response to the operation of turning on the Bluetooth switch in the settings application, the electronic device 100 can determine that Bluetooth is in the turned-on state. When Bluetooth is in the turned-on state, the electronic device 100 can obtain the log entry of the Bluetooth module in the system log to determine whether Bluetooth is in the working state.

[0140] In this way, the electronic device 100 can determine that the first RAT information is Wi-Fi, which is used to record the electronic device 100 transmitting and receiving Wi-Fi radio frequency signals, and determine that the second RAT information is Bluetooth, which is used to record the electronic device 100 transmitting and receiving Bluetooth radio frequency signals.

[0141] It should be noted that the electronic device 100 can also obtain the working status information corresponding to the target RAT through other means. This application embodiment does not limit the specific method of obtaining the working status information corresponding to the target RAT.

[0142] Electronic device 100 can acquire first antenna information and second antenna information. Specifically, electronic device 100 can acquire first antenna information and second antenna information based on the antenna information corresponding to the target RAT. The first antenna information is used to record when electronic device 100 calls the first antenna based on the first RAT, and the second antenna information is used to record when electronic device 100 calls the second antenna based on the second RAT.

[0143] For example, when electronic device 100 simultaneously transmits and receives radio frequency signals corresponding to Wi-Fi and Bluetooth, electronic device 100 can obtain Wi-Fi antenna information and Bluetooth antenna information.

[0144] Specifically, since the Wi-Fi antenna and Bluetooth antenna are hardware components in the electronic device 100, the electronic device 100 typically stores the corresponding Wi-Fi antenna information and Bluetooth antenna information in its firmware or hardware specifications. Therefore, the electronic device 100 can determine the antenna used by Wi-Fi and the antenna used by Bluetooth through the firmware or hardware specifications. For example, Wi-Fi may use the Wi-Fi 2.4GHz Core 0 antenna, while Bluetooth may use an MHB Div antenna that is independent of the Wi-Fi 2.4GHz Core 0 antenna.

[0145] In this application, the Wi-Fi 2.4GHz Core 0 antenna is a naming scheme for the Wi-Fi antenna provided in the embodiment of the application, and the MHB Div antenna is a naming scheme for the Bluetooth antenna provided in the embodiment of the application. In actual applications, the Wi-Fi antenna and the Bluetooth antenna can also adopt other naming schemes, such as the Wi-Fi antenna can be named antenna 1 and the Bluetooth antenna can be named antenna 2. This application does not limit the specific naming scheme of the antenna. For ease of description, the following embodiments will use the antenna called by Wi-Fi as antenna 1 and the antenna called by Bluetooth as antenna 2 for exemplary description.

[0146] In this way, the electronic device 100 can determine that the first antenna information is antenna 1, which is used to record the electronic device 100 calling antenna 1 based on Wi-Fi, and determine that the second antenna information is antenna 2, which is used to record the electronic device 100 calling antenna 2 based on Bluetooth.

[0147] It should be noted that the electronic device 100 can also obtain the antenna information corresponding to the target RAT through other means. This application embodiment does not limit the specific method of obtaining the antenna information corresponding to the target RAT.

[0148] The electronic device 100 can also acquire isolation information between the first antenna and the second antenna, first RAT signal index information, and second RAT signal index information. Specifically, the electronic device 100 can acquire the isolation information between the first antenna and the second antenna, the first RAT signal index information, and the second RAT signal index information based on the operating frequency band information and operating radio frequency path information corresponding to the target RAT. The first RAT signal index information is used to record the signal strength of the first antenna, and the second RAT signal index information is used to record the signal strength of the second antenna.

[0149] For example, when electronic device 100 simultaneously transmits and receives radio frequency signals corresponding to Wi-Fi and radio frequency signals corresponding to Bluetooth, electronic device 100 can obtain the isolation information between antenna 1 corresponding to Wi-Fi and antenna 2 corresponding to Bluetooth.

[0150] Specifically, the isolation information between antenna 1 and antenna 2 is typically obtained by developers through simulation software during the design phase of electronic device 100. This isolation information can be stored in the firmware or hardware specifications of electronic device 100 for use in decoupling scenarios. Electronic device 100 can also record antenna performance-related log information when antennas 1 and 2 are simultaneously transmitting and receiving RF signals to obtain isolation information. For example, the isolation information between antennas 1 and 2 can be 20dB, indicating that based on the predetermined physical locations of antennas 1 and 2, the mutual interference level when the two antennas are operating simultaneously without decoupling by electronic device 100 is 20dB.

[0151] In this way, electronic device 100 can determine the isolation information as 20dB.

[0152] It should be noted that the embodiments of this application do not limit the specific method by which the electronic device 100 obtains the isolation information between the first antenna and the second antenna.

[0153] Furthermore, the electronic device 100 can obtain Wi-Fi signal indicator information based on the Wi-Fi operating frequency band information and operating radio frequency path information. The Wi-Fi signal indicator information can be used to measure the signal strength of the Wi-Fi antenna.

[0154] Specifically, Wi-Fi signal strength information can be represented as the ratio of received signal power to 1 milliwatt (mW), measured in dBm. Electronic device 100 can determine the current Wi-Fi signal strength information through system logs to ascertain the signal strength of the Wi-Fi antenna, thereby determining the degree of interference affecting the Wi-Fi antenna and performing decoupling when the Wi-Fi antenna experiences significant interference. For example, the Wi-Fi signal strength information might be 15 dBm.

[0155] The electronic device 100 can also obtain Bluetooth signal indicator information based on Bluetooth's operating frequency band information and operating radio frequency path information. The Bluetooth signal indicator information can be used to measure the signal strength of the Bluetooth antenna.

[0156] Specifically, Bluetooth signal strength information can be expressed as the ratio of received signal power to 1mW, measured in dBm. Electronic device 100 can determine the current Bluetooth signal strength information through system logs to ascertain the signal strength of the Bluetooth antenna, thereby determining the degree of interference to the Bluetooth antenna and performing decoupling when the Bluetooth antenna experiences significant interference. For example, the Bluetooth signal strength information might be 8dBm.

[0157] It should be noted that this application embodiment does not limit the specific type of signal indicator information, but the electronic device 100 needs to ensure that the type of signal indicator information used to measure the first antenna is the same as the type of signal indicator information used to measure the second antenna. Furthermore, this application embodiment does not limit the specific method by which the electronic device 100 acquires the signal indicator information.

[0158] In this way, after obtaining the above target information, the electronic device 100 can determine whether it is currently in a scenario where the first RAT and the second RAT are simultaneously transmitting and receiving radio frequency signals, so as to determine whether the first antenna and the second antenna need to be decoupled through the above target information.

[0159] However, in the specific implementation process of this application embodiment, it is also necessary to call other antennas besides the first antenna and the second antenna. Therefore, the electronic device 100 needs to ensure that it has callable candidate antennas in order to realize the technical solution of this application embodiment.

[0160] Specifically, the technical solution of this application embodiment is implemented based on the analog beamforming method. Analog beamforming is a wireless communication technology that uses analog signal processing to control the beam direction of an antenna array. In this application embodiment, the electronic device 100 can select a target antenna to form an array antenna with the first antenna. By controlling the beam direction of the array antenna, the beam direction is made to be opposite to the azimuth of the first antenna of the second antenna, thereby improving the isolation between the first antenna and the second antenna.

[0161] Therefore, in order to select a suitable target antenna, the electronic device further needs to acquire third antenna information. Specifically, the electronic device 100 can acquire third antenna information based on the antenna information corresponding to the target RAT. The third antenna information is used to record candidate antennas in the electronic device 100 that were not invoked when the first antenna transmits and receives the radio frequency signal of the first RAT and the second antenna transmits and receives the radio frequency signal of the second RAT. In this way, the electronic device 100 can determine the target antenna from the candidate antennas in subsequent processing.

[0162] For example, when electronic device 100 simultaneously transmits and receives radio frequency signals corresponding to Wi-Fi and Bluetooth, electronic device 100 can identify at least one candidate antenna that is not currently transmitting or receiving radio frequency signals for the first RAT and the second RAT. For instance, when Wi-Fi calls antenna 1 and Bluetooth calls antenna 2, if electronic device 100 determines that antennas N40-3 (antenna 3), 5G Core0 (antenna 4), and 5G Gore1 (antenna 5) are not transmitting or receiving radio frequency signals for the first RAT and the second RAT, then these antennas can be used as candidate antennas for subsequent determination of the target antenna.

[0163] It should be noted that the candidate antenna can transmit and receive radio frequency signals from a third RAT, which is different from the first and second RATs. For example, the candidate antenna can transmit and receive GNSS radio frequency signals.

[0164] The electronic device 100 also needs to obtain the third RAT signal index information based on the operating frequency band information and operating radio frequency path information corresponding to the target RAT. The third RAT signal index information is used to record the signal strength of the candidate antennas. In this way, the electronic device 100 can select a suitable target antenna based on the signal strength of the candidate antennas.

[0165] In this embodiment, the target information includes, but is not limited to, the various information in the examples above. This embodiment does not limit the quantity or type of target information. The target information may also include the first antenna pattern corresponding to the first antenna, the second antenna pattern corresponding to the second antenna, and the candidate antenna pattern corresponding to the candidate antenna, etc., and this target information can be used for subsequent processing.

[0166] In one implementation, the electronic device 100 may include a control unit, an access point (AP), a modem, and a radio frequency (RF) chip. The RF chip can be connected to at least one RF path to control a first antenna, a second antenna, and a candidate antenna. The control unit can acquire at least one target information based on an interface corresponding to the AP, an interface corresponding to the modem, and an interface corresponding to the RF chip. The specific methods by which the electronic device 100 acquires target information based on these hardware devices will be detailed in subsequent embodiments.

[0167] In step S102, the electronic device 100 matches the target information with a preset first mapping table to determine whether to enter the decoupling mode.

[0168] The decoupling mode is used to decouple the first antenna corresponding to the first RAT and the second antenna corresponding to the second RAT.

[0169] In one implementation, the first mapping table includes lookup items, verification items, and configuration items. The electronic device 100 matches the target information with the lookup items and / or verification items in the first mapping table to determine whether to enter decoupling mode. The first mapping table can be a decoupling scenario mapping table.

[0170] In this embodiment, the electronic device 100 can store the first mapping table in at least one of the following forms: lookup table, neural network parameters, and other algorithm parameters. The first mapping table can be pre-stored in the control unit of the electronic device 100, or it can be loaded into the control unit by the AP or Modem when the electronic device 100 is powered on or initialized. Alternatively, lookup items and verification items can be stored in the AP, and configuration items can be stored in the control unit. This embodiment does not limit the specific pre-setting method of the first mapping table.

[0171] For example, the first mapping table is shown in Table 1 below.

[0172] Table 1:

[0173]

[0174]

[0175] In one implementation, step S102 includes steps S1021-S1022.

[0176] Step S1021: Electronic device 100 obtains the lookup item from the first mapping table.

[0177] As shown in Table 1, the search items may include the first RAT search item, the second RAT search item, the first antenna search item, and the second antenna search item.

[0178] It should be noted that since the electronic device 100 can apply multiple RATs, and the isolation levels between any two different RATs are different, the decoupling methods between any two different RATs are also different. To ensure that the decoupling method provided in this embodiment can be applied when any two different RATs are simultaneously transmitting and receiving radio frequency signals, a first mapping table is configured with multiple mapping table elements, such that each mapping table element corresponds to two specific RATs. In this way, the electronic device 100 can match the two RATs currently transmitting and receiving radio frequency signals with the lookup item to apply the corresponding decoupling method to these two RATs.

[0179] For example, the first mapping table has M mapping table elements (M is a positive integer greater than or equal to 1). Each mapping table element has the same items, but the values ​​corresponding to the items are different. This application embodiment only uses the first mapping table element as an example; other mapping table elements can be found in the first mapping table element, and will not be described in detail in this application embodiment.

[0180] The lookup items of the first mapping table element may include a first RAT lookup item set as Wi-Fi, a second RAT lookup item set as Bluetooth, a first antenna lookup item set as antenna 1, and a second antenna lookup item set as antenna 2.

[0181] The lookup items for other mapping table elements may include a first RAT lookup item set to Wi-Fi, a second RAT lookup item set to GNSS, a first antenna lookup item set to antenna 1, and a second antenna lookup item set to antenna 6.

[0182] In step S1022, the electronic device 100 determines whether the acquired first RAT information, second RAT information, first antenna information, and second antenna information are in the search item.

[0183] Electronic device 100 can determine, based on the acquired target information, that the first RAT information is Wi-Fi, the second RAT information is Bluetooth, the first antenna information is antenna 1, and the second antenna information is antenna 2. Thus, the first RAT information corresponds to the lookup item set as Wi-Fi, the second RAT information corresponds to the lookup item set as Bluetooth, the first antenna information corresponds to the lookup item set as antenna 1, and the second antenna information corresponds to the lookup item set as antenna 2. Therefore, electronic device 100 can determine that the first RAT information, the second RAT information, the first antenna information, and the second antenna information are located in the lookup items, thereby determining that electronic device 100 is currently in a scenario where both the first and second RATs are simultaneously transmitting and receiving data, and that antennas 1 and 2 called in this scenario need to be decoupled.

[0184] Generally, since the antenna's location and capabilities are usually determined during the antenna design, if the first RAT information, second RAT information, first antenna information, and second antenna information obtained by the electronic device 100 correspond to each item in the search item, it can usually be determined that antenna 1 and antenna 2 need to be decoupled. However, in order to ensure the accuracy of the current decoupling scenario determined by the electronic device 100, the electronic device 100 can further verify the decoupling scenario.

[0185] In one implementation, step S1022 is followed by steps S1023-S1024.

[0186] In step S1023, the electronic device 100 obtains the verification item corresponding to the search item, wherein the verification item includes at least one of a preset isolation threshold, a preset first RAT signal threshold, a preset second RAT signal threshold, and a preset third RAT signal threshold.

[0187] For example, electronic device 100 has determined through a lookup item that antenna 1 and antenna 2 are currently in a scenario of simultaneously transmitting and receiving radio frequency signals. The electronic device needs to further determine whether antenna 1 and antenna 2 interfere with each other, causing their respective signal transmission efficiency to be affected.

[0188] Specifically, the isolation between antenna 1 and antenna 2 needs to reach 30dB to avoid mutual interference. Wi-Fi signal strength needs to be greater than or equal to 20dBm for good transmission efficiency. Bluetooth signal strength needs to be greater than or equal to 10dBm for good transmission efficiency. Therefore, the preset isolation threshold can be set to 30dB, the preset first RAT signal threshold can be set to 20dBm, and the preset second RAT signal threshold can be set to 10dBm.

[0189] Candidate antennas typically need to have strong signal specifications to be used in conjunction with antenna 1 to form an array antenna, enabling the array antenna to function as an analog beamforming antenna pair. Therefore, the signal specifications of the candidate antennas can be greater than or equal to 15 dBm. The preset third RAT signal threshold can be 15 dBm.

[0190] Furthermore, when verifying the signal performance of candidate antennas, the electronic device 100 can also set an upper limit for the signal performance of candidate antennas. For example, the signal performance of candidate antennas can be less than or equal to 25dBm. That is to say, the preset third RAT signal threshold can include only one entry threshold of 15dBm, or the preset third RAT signal threshold can include two thresholds, namely an entry threshold of 15dBm and an exit threshold of 25dBm.

[0191] It should be noted that the values ​​of the verification items in the above examples are for illustrative purposes only. The specific threshold values ​​depend on the actual situation, and this application embodiment does not limit them.

[0192] In step S1024, the electronic device 100 determines whether the isolation information is less than the isolation threshold, whether the first RAT signal index information is less than the first RAT signal threshold, whether the second RAT signal index information is less than the second RAT signal threshold, and whether the third RAT signal index information is greater than the third RAT signal threshold.

[0193] In one implementation, the electronic device 100 determines whether the isolation information is less than the isolation threshold, whether the first RAT signal indicator information is less than the first RAT signal threshold, whether the second RAT signal indicator information is less than the second RAT signal threshold, and whether the third RAT signal indicator information is greater than the third RAT signal threshold and less than the third RAT signal threshold.

[0194] For example, if electronic device 100 obtains isolation information of 20dB, it needs to compare 20dB with 30dB to determine if 20dB is less than 30dB. If electronic device 100 obtains first RAT signal index information of 15dBm, it needs to compare 15dBm with 20dBm to determine if 15dBm is less than 20dBm. If electronic device 100 obtains second RAT signal index information of 8dBm, it needs to compare 8dBm with 10dBm to determine if 8dBm is less than 10dBm. If electronic device 100 obtains third RAT signal index information corresponding to antenna 3 of 17dBm, it needs to compare 17dBm with the entry threshold of 15dBm to determine if 17dBm is greater than 15dBm. The electronic device 100 can also obtain the third RAT signal index corresponding to antenna 4 as 14dBm, and needs to compare 14dBm with 15dBm to determine whether 14dBm is greater than 15dBm. The electronic device 100 can also obtain the third RAT signal index corresponding to antenna 5 as 30dBm, and needs to compare 30dBm with 15dBm to determine whether 30dBm is greater than 15dBm.

[0195] Furthermore, the electronic device 100 can also compare the third RAT signal indicator information of 17dBm corresponding to antenna 3 with the exit threshold of 20dBm to determine whether 17dBm is less than 20dBm. The electronic device 100 can also compare the third RAT signal indicator information of 14dBm corresponding to antenna 4 with the exit threshold of 20dBm to determine whether 14dBm is less than 20dBm. The electronic device 100 can also compare the third RAT signal indicator information of 30dBm corresponding to antenna 5 with the exit threshold of 20dBm to determine whether 30dBm is less than 20dBm.

[0196] The above comparison processes can be implemented by the electronic device 100 based on software programs. The specific comparison methods in the embodiments of this application are not limited.

[0197] In step S103, if the target information matches the preset first mapping table, the electronic device 100 enters the decoupling mode.

[0198] In one implementation, when the first RAT information, the second RAT information, the first antenna information, and the second antenna information are in the lookup item, and / or when the isolation information is less than the isolation threshold, the first RAT signal index information is less than the first RAT signal threshold, the second RAT signal index information is less than the second RAT signal threshold, and the third RAT signal index information is greater than the third RAT signal threshold, the electronic device 100 enters the decoupling mode.

[0199] For example, when the first RAT information is Wi-Fi, the second RAT information is Bluetooth, the first antenna information is antenna 1, and the second antenna information is antenna 2, all of the above information is in the lookup item. In this way, the electronic device 100 is in a scenario where Wi-Fi and Bluetooth are simultaneously transmitting and receiving radio frequency signals.

[0200] Furthermore, the isolation information between antenna 1 and antenna 2 is 20dBm, which is less than 30dBm; the first RAT signal index information is 15dBm, which is less than the first RAT signal threshold of 20dBm; and the second RAT signal index information is 8dBm, which is less than the second RAT signal threshold of 10dBm. Thus, electronic device 100 determines that the isolation between antenna 1 and antenna 2 is insufficient to meet the requirements for concurrent Wi-Fi and Bluetooth. The signal indices of both Wi-Fi and Bluetooth are affected and cannot reach the required signal strength.

[0201] Furthermore, the third RAT signal index information of 17dBm corresponding to antenna 3 is greater than the entry threshold of the third RAT signal threshold of 15dBm and less than the exit threshold of the third RAT signal threshold of 20dBm. Thus, there is a candidate antenna in electronic device 100 that can form an array antenna with antenna 1, and the signal strength of the candidate antenna meets the requirements.

[0202] The third RAT signal index information corresponding to antennas 4 and 5 provided in the above example does not meet the third RAT signal threshold. Therefore, antennas 4 and 5 cannot be used as candidate antennas.

[0203] In other words, when the target information currently acquired by the electronic device 100 matches the first mapping table element in the preset first mapping table, the electronic device 100 can enter the decoupling mode.

[0204] Since the lookup items, verification items, and configuration items of the first mapping table can all be stored in the control unit of the electronic device 100, the electronic device 100 can execute the above steps S102 and S103 through the control unit.

[0205] When the lookup items, verification items, and configuration items of the first mapping table are all stored in the control unit of the electronic device 100, the electronic device 100 can execute the following steps S104 through the control unit.

[0206] Figure 7 This is the second interactive schematic diagram of the antenna decoupling method provided in the embodiments of this application.

[0207] like Figure 7 As shown, in some other implementations, the lookup items and verification items of the first mapping table can be stored in the AP. Therefore, the electronic device 100 can also perform the above steps S101-S103 through the AP. This application embodiment does not limit the specific manner in which steps S101-S103 are performed.

[0208] With the lookup item and verification item in the first mapping table stored in the AP, after executing step S103, the AP can send an index value for indexing to the configuration item and a decoupling command for entering the decoupling mode to the control unit. The electronic device 100 can then execute the following step S104 based on the decoupling command received by the control unit.

[0209] In step S104, in decoupling mode, electronic device 100 determines the target antenna according to the first mapping table.

[0210] Specifically, electronic device 100 determines the target antenna based on the configuration items in the first mapping table.

[0211] In one implementation, the electronic device 100 retrieves the configuration item corresponding to the lookup item based on the index value. The configuration item includes the tuning state information of the candidate antennas. The electronic device 100 can determine the tuning state information of the target antenna based on the tuning state information of the candidate antennas, thereby determining the target antenna. Since the electronic device 100 has multiple candidate antennas, the same lookup item may correspond to different configuration items in different mapping table elements. For example, in the first mapping table element, based on the lookup item and verification item of the aforementioned embodiment, the configuration item can be determined to include the tuning state information of antenna 3. In the second mapping table element, based on the lookup item and verification item of the aforementioned embodiment, the configuration item can be determined to include the tuning state information of antenna 6. Antenna 6 is an antenna whose corresponding third RAT signal index meets the third RAT signal threshold. The electronic device 100 can select one of antenna 3 and antenna 6 as the target antenna. In this embodiment, antenna 3 is used as the target antenna for illustrative purposes.

[0212] The configuration items also include at least one of the following: tuning state information of the first antenna, tuning state information of the second antenna, target phase shifter information corresponding to the array antenna, phase information corresponding to the target phase shifter, RF switch information corresponding to the array antenna, RF switch information corresponding to the second antenna, and switch status information corresponding to each RF switch. The tuning state is typically the configuration state of the antenna when receiving or transmitting RF signals. Specifically, the configuration state can be the configuration state for a specific frequency.

[0213] In other words, electronic device 100 needs to select the required mapping table element and configure the radio frequency path according to the configuration items in that mapping table element. For example, electronic device 100 locates the first mapping table element according to the first mapping table to determine the target antenna as antenna 3. When not in decoupling mode, antenna 3 can be used to transmit and receive GNSS radio frequency signals.

[0214] The configuration items of the first mapping table element can include the tuning state of the target antenna. The tuning state of the target antenna can be the tuning state of antenna 3, specifically configured as a first tuning state. This allows the electronic device 100 to change the resonant frequency of antenna 3 according to the first tuning state, thereby changing antenna 3 from transmitting / receiving GNSS RF signals to transmitting / receiving Wi-Fi RF signals. It should be noted that the first tuning state corresponding to the target antenna can be represented numerically, for example, as state 1. Each antenna can have multiple tuning states, such as state 0, state 1, and state 2. Each tuning state is preset based on the antenna's own performance, and different antennas correspond to different tuning states.

[0215] The configuration items of the first mapping table element may also include the tuning state of the first antenna. The tuning state of the first antenna can be the tuning state of antenna 1, specifically configured as a first tuning state. In this way, the electronic device 100 can change the resonant frequency of antenna 1 according to the first tuning state, so that the resonant frequency of antenna 1 is adapted to the resonant frequency of antenna 3, and antenna 1 and antenna 3 can jointly transmit and receive Wi-Fi radio frequency signals. It should be noted that the first tuning state corresponding to the first antenna can be represented in numerical form, for example, as state 1. However, the state 1 corresponding to the target antenna and the state 1 corresponding to the first antenna are not the same state.

[0216] The configuration items of the first mapping table element may also include the tuning state of the second antenna, which can be the tuning state of antenna 2, specifically configured as the second tuning state. In this way, the electronic device 100 can change the resonant frequency of antenna 2 according to the first tuning state so that the resonant frequency of antenna 2 is adapted to the transmission and reception of Bluetooth radio frequency signals.

[0217] The configuration items of the first mapping table element may also include a target phase shifter, which can be a phase shifter connected to the antenna 1. Specifically, it can be configured as a first phase shifter. In this way, the electronic device 100 can change the phase of the radio frequency signal transmitted and received by the antenna 1 based on the first phase shifter, thereby affecting the beam and shape of the first antenna pattern corresponding to the antenna 1.

[0218] The configuration items of the first mapping table element may also include the phase corresponding to the target phase shifter. The phase corresponding to the target phase shifter can be the phase of the first phase shifter, specifically configured as π / 4. In this way, the electronic device 100 can accurately adjust the phase of the radio frequency signal transmitted and received by the antenna 1 so that the radio frequency signal is coupled with the antenna 1.

[0219] The configuration items of the first mapping table element may also include a first target RF switch, a second target RF switch, ..., a Kth target RF switch (K is a positive integer greater than or equal to 1). The target RF switches can be switches on the RF paths of antennas 1, 2, and 3. Specifically, the first target RF switch can be configured as a first switch, the second target RF switch as a second switch, and the Kth target RF switch as a Kth switch. In this way, the electronic device 100 can clearly identify the switches to be adjusted to connect the RF paths of antennas 1, 2, and 3. The first switch can be represented numerically, for example, as switch 1.

[0220] The configuration items of the first mapping table element may also include the state of the first target RF switch, the state of the second target RF switch, ..., the state of the Kth target RF switch. The state of the target RF switch can be the state of the switch on the RF path where antenna 1, antenna 2, and antenna 3 are located. The state of the first target RF switch can be specifically configured as a first switch state, which can be represented in numerical form, such as state 1, indicating that the switch is on. In this way, the electronic device 100 can adjust the target RF switch to the corresponding state to connect the RF path where antenna 1, antenna 2, and antenna 3 are located.

[0221] In step S105, the electronic device 100 generates a target antenna pattern based on the first antenna pattern corresponding to the first antenna and the second antenna pattern corresponding to the target antenna. The notch direction corresponding to the target antenna pattern is opposite to the first antenna azimuth of the second antenna, so as to decouple the first antenna and the second antenna.

[0222] The electronic device 100 configures the first antenna, the target antenna, and the second antenna based on the values ​​of the configuration items in the foregoing embodiments, thereby generating the target antenna radiation pattern.

[0223] In one implementation, step S105 includes steps S1051-S1055.

[0224] In step S1051, the electronic device 100 adjusts the phase of the target phase shifter based on the phase information corresponding to the target phase shifter.

[0225] In step S1052, the electronic device 100 tunes the first antenna based on the tuning state information of the first antenna.

[0226] In step S1053, the electronic device 100 tunes the second antenna based on the tuning state information of the second antenna.

[0227] In step S1054, the electronic device 100 tunes the target antenna based on the tuning state information of the target antenna.

[0228] In step S1055, the electronic device 100 adjusts all the radio frequency switches in the radio frequency path where the first RAT is located and the radio frequency switch in the radio frequency path where the second RAT is located based on the radio frequency switch information corresponding to the first antenna, the radio frequency switch information corresponding to the target antenna, the radio frequency switch information corresponding to the second antenna, and the switch status information corresponding to each radio frequency switch.

[0229] It should be noted that the execution order of steps S1051-S1055 is not limited in this embodiment of the application, and the specific execution order can be set according to the hardware configuration.

[0230] In this way, the radio frequency path where the first RAT is located and the radio frequency path where the second RAT is located are connected, and the first antenna and the target antenna form an array antenna. This array antenna can be used as a simulated beamforming antenna pair to generate a target antenna pattern with a notch. Furthermore, the notch direction can be adjusted according to the phase of the target phase shifter so that the notch direction points to the first antenna azimuth of the second antenna.

[0231] In one implementation, the target phase shifter includes at least one of an LC switching network and a voltage-controlled varactor diode. The specific type of the target phase shifter is not limited in the embodiments of this application.

[0232] For example, electronic device 100 configures antenna 1 to its corresponding first tuning state, antenna 3 to its corresponding first tuning state, first switch to a first switching state, and second switch to a first switching state. This connects the Wi-Fi radio frequency path, and antennas 1 and 3 form an array antenna. In electronic device 100, the Wi-Fi uplink radio frequency signal can be amplified by a PA and then split into two paths by a power divider. One path passes through a first phase shifter and is coupled to antenna 1 via the first switch, while the other path is coupled to antenna 3 via the second switch. After configuring the first phase shifter to π / 4, antennas 1 and 3 can be considered as equivalent antennas for transmitting and receiving Wi-Fi radio frequency signals. The first antenna pattern corresponding to antenna 1 and the second antenna pattern corresponding to antenna 3 can form the following pattern: Figure 4 The target antenna pattern in region C1, shown in B, is illustrated. The notch direction of this target antenna pattern points towards the azimuth of the first antenna corresponding to antenna 2.

[0233] Furthermore, in the electronic device 100, the downlink radio frequency signal of Wi-Fi can be received by both antenna 1 and antenna 3. The part of the Wi-Fi radio frequency signal received by antenna 1 enters the power divider after passing through the first switch and the first phase shifter with the phase configured as π / 4. The other part of the Wi-Fi radio frequency signal received by antenna 3 enters the power divider after passing through the second switch. The power divider combines the two radio frequency signals and sends them to the radio frequency chip for further processing via LNA.

[0234] The signal transmission process of the electronic device 100 in the hardware device will be described in detail in subsequent embodiments.

[0235] In this embodiment, the electronic device 100 uses an analog beamforming method to form an array antenna with the first antenna and the target antenna. The radiation patterns of the first antenna and the second antenna are adjusted so that the radiation pattern of the target antenna is pointed to the azimuth of the first antenna. In this way, within the compact spatial layout of the electronic device, the antenna isolation between the array antenna transmitting and receiving radio frequency signals of the first RAT and the second antenna transmitting and receiving radio frequency signals of the second RAT is greatly improved, thus achieving antenna decoupling.

[0236] Figure 8 This is the second flowchart of the antenna decoupling method provided in the embodiments of this application.

[0237] like Figure 8 As shown, in one implementation, steps S106-S107 are included after step S102.

[0238] In step S106, if the target information does not match the preset first mapping table, the electronic device 100 enters the non-decoupling mode.

[0239] In one implementation, when at least one of the first RAT information, the second RAT information, the first antenna information, and the second antenna information is not in the lookup item, and / or, the isolation information is greater than or equal to the isolation threshold, and / or, the first RAT signal indicator information is greater than or equal to the first RAT signal threshold, and / or, the second RAT signal indicator information is greater than or equal to the second RAT signal threshold, and / or, the third RAT signal indicator information is less than the third RAT signal threshold, the electronic device 100 enters the decoupling mode.

[0240] For example, if the target information obtained by electronic device 100 does not include the first RAT information, then the first RAT information is not in the lookup item. This situation may indicate that electronic device 100 has currently exited the wireless local area network and is not connected to Wi-Fi. In this case, Wi-Fi and Bluetooth will not interfere with each other, and antenna 1 and antenna 2 do not need to be decoupled.

[0241] If the target information acquired by the electronic device 100 does not include the first RAT information, the electronic device 100 usually does not include the first antenna information either.

[0242] Correspondingly, if the target information acquired by the electronic device 100 does not include the second RAT information, then the second RAT information is not in the search item. This situation may indicate that the electronic device 100 has disconnected the Bluetooth connection. At this time, Wi-Fi and Bluetooth will not interfere with each other, and antenna 1 and antenna 2 do not need to be decoupled.

[0243] When the isolation information between antenna 1 and antenna 2 is greater than the isolation threshold, it indicates that the isolation between Wi-Fi and Bluetooth has met the concurrency requirements, and decoupling between antenna 1 and antenna 2 is not required. When the Wi-Fi signal indicators of antenna 1 and the Bluetooth signal indicators of antenna 2 reach the corresponding signal thresholds, it indicates that the current Wi-Fi and Bluetooth signals have good strength, and decoupling between antenna 1 and antenna 2 is not required.

[0244] When the third RAT signal indicator information is less than the third RAT signal threshold, the electronic device 100 does not have a candidate antenna that can form an array antenna with the antenna 1, and analog beamforming cannot be achieved. Therefore, the electronic device 100 cannot provide a callable target antenna for decoupling. In one implementation, when the lookup item, verification item, and configuration item of the first mapping table are all stored in the control unit of the electronic device 100, the electronic device 100 can execute the following step S107 through the control unit.

[0245] In step S107, in non-decoupling mode, the electronic device 100 adjusts the radio frequency path according to the first mapping table, wherein the first mapping table also includes non-decoupling configuration items.

[0246] In one implementation, the first mapping table is shown in Table 2 below.

[0247] Table 2:

[0248]

[0249]

[0250] The electronic device configures the radio frequency paths of the first antenna, the target antenna, and the second antenna based on the values ​​of the aforementioned non-decoupling configuration items. Specific configuration methods can be found in the foregoing embodiments, and will not be elaborated upon here.

[0251] In this way, when the first and second antennas do not need to transmit and receive radio frequency signals simultaneously, the target antenna can be used to transmit and receive radio frequency signals of the third RAT, such as GNSS radio frequency signals.

[0252] In one implementation, while the lookup and verification items of the first mapping table are stored in the AP, the second mapping table can be stored in the control unit. The second mapping table includes non-decoupling configuration items. After executing step S106, the AP can send an index value for indexing into the second mapping table and a non-decoupling instruction for entering the non-decoupling mode to the control unit. The electronic device 100 can then execute the following step S108 based on the non-decoupling instruction received by the control unit.

[0253] In step S108, in non-decoupling mode, electronic device 100 adjusts the radio frequency path according to the second mapping table, wherein the second mapping table includes non-decoupling configuration items.

[0254] The specific implementation of step S108 can be found in step S107, and will not be described in detail in this embodiment.

[0255] In this embodiment of the application, the electronic device 100 can restore the non-decoupling mode in the scenario where the first antenna and the second antenna do not transmit and receive radio frequency signals at the same time, so that the target antenna can be applied to its initial RAT.

[0256] Figure 9 This is the second flowchart of the antenna decoupling method provided in the embodiments of this application.

[0257] like Figure 9 As shown, in some other embodiments, the method may include the following steps S201-S203.

[0258] Step S201: Obtain the first antenna pattern corresponding to the first antenna and the second antenna pattern corresponding to the target antenna. The first antenna and the target antenna are used to form an array antenna, which is used to transmit and receive radio frequency signals of the first wireless access technology (RAT) in the electronic device.

[0259] Step S202: Obtain the orientation of the first antenna corresponding to the second antenna. The second antenna is used to transmit and receive radio frequency signals of the second RAT in the electronic device. The second RAT is different from the first RAT.

[0260] Step S203: Generate a target antenna pattern based on the first antenna pattern and the second antenna pattern, wherein the notch direction corresponding to the target antenna pattern is opposite to the azimuth of the first antenna, so as to decouple the first antenna from the second antenna.

[0261] In the embodiments provided above, various schemes of the antenna decoupling method provided in this application have been described from the perspective of electronic device 100. It is understood that, in order to achieve the above functions, electronic device 100 includes hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should readily recognize that, based on the units and algorithm steps of the examples described in conjunction with the embodiments disclosed herein, this application can be implemented in hardware or a combination of hardware and computer software. Whether a function is executed in hardware or by computer software driving hardware depends on the specific application and design constraints of the technical solution.

[0262] Figure 10 This is a schematic diagram of the antenna decoupling device provided in the embodiments of this application.

[0263] like Figure 10 As shown, in one implementation, the antenna decoupling device 200 includes a control unit 201, an AP 202, a modem 203, an RF chip 204, at least one PA 205, at least one LNA 206, a filter 207, a power divider 208, a phase shifter 209, at least one RF switch 210, a first antenna 211, a target antenna 212, and a second antenna (…). Figure 8 (Not shown).

[0264] The control unit 201 is electrically connected to the AP 202, the Modem 203, and the radio frequency chip 204.

[0265] The control unit 201 can manage and schedule the AP202 to perform tasks. The control unit 201 can send instructions to the AP202 through the control bus, and the AP202 can execute these instructions and process data.

[0266] Furthermore, the AP202 can communicate with the Modem203 via the system bus or a dedicated interface.

[0267] The data processed by Modem203 needs to be modulated by RF chip 204 and converted into radio wave form.

[0268] Modem 203 sends digital signals to the radio frequency chip via the baseband interface. Radio frequency chip 204 processes the digital signals through devices such as PA 205, LNA 206, filter 207, power divider 208, phase shifter 209, and radio frequency switch 210 in the radio frequency signal path to generate wireless signals, which are then transmitted and received through the first antenna 211, the target antenna 212, and the second antenna.

[0269] In one implementation, RF chip 204 corresponds to the first RF path. The transmit port (Txport) of RF chip 204 is electrically connected to PA 205 to transmit uplink RF signals to PA 205. PA 205 is electrically connected to one end of power divider 208. The other end of power divider 208 is split into two paths. One path is electrically connected to phase shifter 209, which is further connected to first antenna 211 via first switch 2101. The other path of power divider 208 is connected to target antenna 212 via second switch 2102.

[0270] For example, when the first radio frequency path transmits the uplink radio frequency signal corresponding to Wi-Fi, the uplink radio frequency signal is amplified by PA205 and then split into two paths by power divider 208. One path is coupled to the first antenna 211 via phase shifter 209 and first switch 2101, and the other path is coupled to the target antenna 212 via second switch 2102. This process can be controlled by control unit 201 through layer-by-layer communication of AP202, Modem203 and radio frequency chip 204 to control the first radio frequency path.

[0271] The RF chip 204 also corresponds to a second RF path. The first receiving port (Rx port) of the RF chip 204 is connected to the first LNA 2061. The first LNA 2061 is electrically connected to the filter 207. The filter 207 is further coupled to the first antenna 211 through the first switch 2101.

[0272] In the first RF path, a third switch 2103 can be provided between PA205 and power divider 208. Correspondingly, the third switch 2103 can also be located between the first LNA2061 and filter 207 in the second RF path. In this way, the third switch 2103 can realize the connection between the first RF path and the second RF path.

[0273] For example, when transmitting the downlink RF signal corresponding to Wi-Fi based on the first RF path and the second RF path, the downlink RF signal is received by the first antenna 211 and the target antenna 212. A portion of the downlink RF signal received by the first antenna 211 passes through the first switch 2101 and the phase shifter 209 before entering the power divider 208. A portion of the downlink RF signal received by the target antenna 212 passes through the second switch 2102 before entering the power divider 208. The power divider 208 combines the two downlink RF signals and couples them to the first LNA 2061 via the filter 207. The first LNA 2061 then sends the downlink RF signal to the RF chip 204 for processing.

[0274] In one implementation, the antenna decoupling device 200 further includes a duplexer 213.

[0275] The RF chip 204 also corresponds to a third RF path. The second receiving port of the RF chip 204 is connected to the second LNA 2062, which is further coupled to the target antenna 212 through the duplexer 213 and the second switch 2102. In this way, when the target antenna 212 is not in decoupling mode, it can be used to transmit and receive RF signals of the third RAT, such as GNSS RF signals.

[0276] It should be noted here that... Figure 10 The dashed lines in the diagram illustrate the control flow from the control unit 201 to at least one radio frequency switch 210. In this way, the control unit 201 can control the radio frequency path.

[0299] Furthermore, the control unit 201 is also configured to control the radio frequency chip 204 to determine the target phase shifter in the phase shifter based on the target phase shifter information.

[0300] Step S305: Generate a target antenna pattern based on the first antenna pattern corresponding to the first antenna 211 and the second antenna pattern corresponding to the target antenna 212. The notch direction corresponding to the target antenna pattern is opposite to the first antenna azimuth of the second antenna, so as to decouple the first antenna 211 and the second antenna.

[0301] In one implementation, the control unit 201 is further configured to: control the radio frequency chip 204 to adjust the phase of the target phase shifter based on the phase information corresponding to the target phase shifter, so as to adjust the first antenna pattern and the second antenna pattern, so that the first antenna pattern and the second antenna pattern generate the target antenna pattern.

[0303] The specific implementation of steps S303-S305 can be found in steps S103-S105 of the aforementioned embodiments. This application will not elaborate further on these details.

[0311] In other embodiments, the control unit 201 may be configured to perform the following steps S401-S403.

[0312] Step S401: When the first antenna 211 transmits and receives radio frequency signals of the first RAT and the second antenna transmits and receives radio frequency signals of the second RAT, determine whether to enter the decoupling mode. The decoupling mode is used to decouple the first antenna 211 corresponding to the first RAT and the second antenna corresponding to the second RAT.

[0313] In step S402, when entering decoupling mode, the target antenna 212 is determined so that the target antenna 212 and the first antenna 211 form an array antenna, which is used to transmit and receive radio frequency signals of the first RAT.

It adjusts the first antenna pattern corresponding to the first antenna 211 and the second antenna pattern corresponding to the target antenna 212, so that the target antenna pattern of the array antenna points to the azimuth of the first antenna corresponding to the second antenna. Thus, within the compact spatial layout of the electronic device, the antenna isolation between the array antenna transmitting and receiving RF signals for the first RAT and the second antenna transmitting and receiving RF signals for the second RAT is significantly improved, achieving antenna decoupling. Furthermore, in scenarios where the first antenna 211 and the second antenna do not transmit and receive RF signals simultaneously, the antenna decoupling device 200 can restore the non-decoupling mode, allowing the target antenna 212 to be used in its initial RAT.
