The technical solutions in the embodiments of the present application will be described clearly and in detail below with reference to the accompanying drawings. Among them, in the description of the embodiments of this application, unless otherwise stated, "/" means or, for example, A/B can mean A or B; "and/or" in the text is only a way to describe related objects. The association relationship means that there can be three relationships. For example, A and/or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiment of the present application , "plurality" means two or more than two.

Hereinafter, the terms “first” and “second” are used for descriptive purposes only and shall not be understood as implying or implying relative importance or implicitly specifying the quantity of indicated technical features. Therefore, the features defined as “first” and “second” may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, “plurality” The meaning is two or more.

Currently, electronic devices can perform multiple communication services at the same time and meet users' various entertainment and usage needs.

For example, a laptop computer can use a wireless fidelity (Wi-Fi) network to access the Internet and at the same time use the Wi-Fi network to communicate with a screen projection device and activate the screen projection function of the laptop computer, thereby satisfying the user's needs to access the Internet at the same time. and the need to use the screencasting function.

However, there are certain flaws in surfing the Internet and activating the screen mirroring function at the same time. Since both surfing the Internet and activating the screen mirroring function are implemented through a Wi-Fi chip of the laptop, the speed of Internet access services is low, the delay is large when using the screen mirroring function, and even the screen mirroring may freeze.

In addition, due to the hinge design of the notebook computer, the notebook computer has multiple folding configurations, and its opening and closing angles can present angles such as 0 degrees, 110 degrees, 180 degrees, 360 degrees, etc. Then, for a notebook computer that can perform communication services in multiple folding forms, the antenna of the notebook computer needs to have good performance indicators and coverage effects in all folding forms to ensure that the notebook computer can perform communication services in various folding forms. There is good communication effect in all forms.

It can be seen that in order to ensure the communication effect of Internet access business and screen projection function, a Wi-Fi chip can be added to ensure the concurrent communication efficiency of multiple services through dual Wi-Fi chips. In addition, in order to ensure that the laptop can operate on multiple There is good communication efficiency in the folded form, so there needs to be a backup antenna that can be switched to the backup antenna to enhance the signal strength when the antenna signal is weak. However, for a device that only contains one Wi-Fi chip, adding another Wi-Fi chip will require a set of antennas for the additional Wi-Fi chip, plus a backup antenna, which will require a total of additional 100% on the laptop. Equipped with two sets of antennas, this will increase the production cost of electronic equipment and make the antenna design process more complex.

Therefore, how to implement dual Wi-Fi chips and meet the communication quality of the device using antennas to send and receive signals, while reducing the number of antennas as much as possible, is an issue that needs to be solved urgently.

In order to solve the above problems, embodiments of the present application provide an antenna multiplexing method. The antenna multiplexing method is suitable for electronic devices containing dual Wi-Fi chips. The dual Wi-Fi chips include: a main Wi-Fi chip and an auxiliary Wi-Fi chip. Wi-Fi chip. Among them, this antenna multiplexing method can reuse the antenna corresponding to the auxiliary Wi-Fi chip and the backup antenna required by the main Wi-Fi chip to reduce the number of antennas that need to be added as much as possible.

Specifically, the electronic device may be equipped with a main antenna and a multiplexed antenna. The main antenna is the antenna corresponding to the main Wi-Fi chip, and the multiplexed antenna is the antenna corresponding to the auxiliary Wi-Fi chip. That is to say, the main antenna is used for To send and receive signals from the main Wi-Fi chip, the multiplexed antenna can be used to send and receive signals from the auxiliary Wi-Fi chip. In addition, the multiplexed antenna can also be used to send and receive signals from the main Wi-Fi chip. Among them, the electronic device can determine whether the main Wi-Fi chip needs to switch to a multiplexed antenna based on the working status of the auxiliary Wi-Fi chip and the signal quality when the main Wi-Fi chip uses different antennas to send and receive signals. Use the antenna to send and receive signals from the main Wi-Fi chip or the auxiliary Wi-Fi chip.

In this way, it can not only ensure that when there are multiple communication services in the electronic device, it can share the computing workload of the main Wi-Fi chip through the auxiliary Wi-Fi chip, and add an additional set of antennas to transmit data at the same time, improving the communication rate of the service. Increase network bandwidth and reduce communication delay. At the same time, when the main Wi-Fi chip is working, it can communicate with the best signal strength by switching the main antenna and the multiplexed antenna, ensuring that electronic devices use the antenna to send and receive signals. communication quality. In general, when using the Wi-Fi function to send and receive data, by reusing the antenna corresponding to the auxiliary Wi-Fi chip, the antenna corresponding to the auxiliary Wi-Fi chip can also be used as the main Wi-Fi chip. As a spare antenna, the electronic device only needs to be equipped with two sets of antennas. These two sets of antennas simultaneously meet the configuration requirements of the dual Wi-Fi chips of the electronic device, ensure the communication effect of the electronic device, and reduce the number of antennas of the electronic device as much as possible. The quantity reduces the process difficulty of antenna design and reduces the production cost of electronic equipment.

The application layer and application framework layer run in virtual machines. The virtual machine executes the java files of the application layer and application framework layer into binary files. The virtual machine is used to perform object life cycle management, stack management, thread management, security and exception management, and garbage collection and other functions.

System libraries can include multiple functional modules. For example: surface manager (surface manager), media libraries (Media Libraries), 3D graphics processing libraries (for example: OpenGL ES), 2D graphics engines (for example: SGL), etc.

The surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications.

The media library supports playback and recording of a variety of commonly used audio and video formats, as well as static image files, etc. The media library can support a variety of audio and video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, composition, and layer processing.

2D Graphics Engine is a drawing engine for 2D drawing.

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

The following exemplifies the workflow of the software and hardware of the electronic device 100 in conjunction with capturing the photographing scene.

When the touch sensor 180K receives a touch operation, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes touch operations into raw input events (including touch coordinates, timestamps of touch operations, and other information). Raw input events are stored at the kernel level. The application framework layer obtains the original input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation and the control corresponding to the click operation as a camera application icon control as an example, the camera application calls the interface of the application framework layer to start the camera application, and then starts the camera driver by calling the kernel layer. Camera 193 captures still images or video.

The following describes the multi-antenna scenario provided by the embodiment of the present application with reference to Figures 2-4.

As shown in FIG. 2 , the electronic device 100 may include: a processing unit, a main Wi-Fi chip, a secondary Wi-Fi chip, multiple signal switching units, and multiple antennas.

Among them, the processing unit is used to control and manage the work of the main Wi-Fi chip and the auxiliary Wi-Fi chip. For example, the processing unit may be a processor 101, and the processing unit may be connected to the main Wi-Fi chip and the auxiliary Wi-Fi chip through a communication interface. The main Wi-Fi chip and the auxiliary Wi-Fi chip can send and receive wireless signals through the antenna, allowing the electronic device 100 to establish a Wi-Fi communication connection with other devices. The signal switching unit can be used to control Control the connection of different lines. For example, the signal switching unit may be a radio frequency switch, including a single-pole double-throw switch or a four-pole double-throw switch. The electronic device 100 can control the connectivity of the Wi-Fi chip to different antennas through the signal switching unit to control the antennas used by the main Wi-Fi chip and the auxiliary Wi-Fi chip to send and receive signals.

For specific descriptions of the processor 101, the main Wi-Fi chip, and the auxiliary Wi-Fi chip, please refer to the relevant content in Figure 1A, and will not be described again here.

As can be seen from Figure 2, the processing unit is connected to one end of the main Wi-Fi chip and the auxiliary Wi-Fi chip respectively. The A1 end of the signal switching unit A is connected to one end of the main Wi-Fi chip. The A2 end of the signal switching unit A is connected to the antenna. 1. The A3 terminal is connected to the C1 terminal of the signal switching unit C, the B1 terminal of the signal switching unit B is connected to one end of the main Wi-Fi chip, the B2 terminal of the signal switching unit B is connected to the antenna 2, and the B3 terminal is connected to the C2 terminal of the signal switching unit C. , the C3 terminal and C4 terminal of the signal switching unit C are respectively connected to both ends of the auxiliary Wi-Fi chip, and the C5 terminal and C6 terminal of the signal switching unit C are connected to the antenna 3 and the antenna 4 respectively. Among them, the signal switching unit A and the signal switching unit B may be single-pole double-throw switches, and the signal switching unit C may be a four-pole double-throw switch.

It should be understood that in the actual circuit, the processing unit, the main Wi-Fi chip, the auxiliary Wi-Fi chip, the signal switching units A-C, and the antennas 1-4 may also have other interfaces and be connected to other devices, such as signal switching. Units A-C also have interfaces for connecting power supplies and input control signals. Among them, the power supply is used to supply power to the signal switching units A-C, and the control signal is used to control the conduction of different lines by the signal switching units A-C.

The specific implementation process of the main Wi-Fi chip and the auxiliary Wi-Fi chip selecting the antenna to send and receive signals is described below based on the line conduction status of the signal switching units A-C respectively:

1) Signal switching unit A

For the control signal input to the signal switching unit A, the control signal can be used to control the connection between the A1 terminal and the A2 terminal of the signal switching unit A (see the solid line in the signal switching unit A shown in Figure 2). At this time, the main Wi -Fi chip can send and receive signals through antenna 1; alternatively, the control signal can be used to control the connection from the A1 end to the A3 end of the signal switching unit A (see the dotted line in the signal switching unit A shown in Figure 2). At this time, the main Wi -The Fi chip does not send and receive signals through antenna 1. Furthermore, controlling the connection of the signal switching unit C to the line can enable the main Wi-Fi chip to send and receive signals through antenna 3.

2) Signal switching unit B

For the control signal input to the signal switching unit B, the control signal can be used to control the connection between the B1 end and the B2 end of the signal switching unit B (see the solid line in the signal switching unit B shown in Figure 2). At this time, the main Wi -Fi chip can send and receive signals through antenna 2; alternatively, the control signal can be used to control the connection from B1 end to B3 end of signal switching unit B (see the dotted line in signal switching unit B shown in Figure 2). At this time, the main Wi -The Fi chip does not send and receive signals through the antenna 2. Furthermore, controlling the connection of the signal switching unit C line allows the main Wi-Fi chip to send and receive signals through the antenna 4.

3) Signal switching unit C

For the control signal input to the signal switching unit C, the control signal can be used to control the connection between the C1 terminal and the C5 terminal of the signal switching unit C (see the dotted line in the signal switching unit C shown in Figure 2). At this time, during the signal switching When the A1 end of unit A is connected to the A3 end, the main Wi-Fi chip can send and receive signals through the antenna 3; in addition, the control signal can also be used to control the connection of the C2 end to the C6 end of the signal switching unit C (see Figure 2 The dotted line in the signal switching unit C shown above). At this time, when the B1 end to the B3 end of the signal switching unit B are connected, the main Wi-Fi chip sends and receives signals through the antenna 4. Alternatively, the control signal can be used to control the connection between the C3 terminal and the C5 terminal of the signal switching unit C (see the solid line in the signal switching unit C shown in Figure 2). At this time, the auxiliary Wi-Fi chip can send and receive signals through the antenna 3 ; In addition, the control signal can also be used to control the connection from the C4 end to the C6 end of the signal switching unit C (see the solid line in the signal switching unit C shown in Figure 2). At this time, the auxiliary Wi-Fi chip can also pass the antenna 4. Send and receive signals.

Initially, signal switching unit A can connect A1 to A2 by default, and signal switching unit B can connect B1 to B2 by default. In this way, the main Wi-Fi chip can send and receive signals through antennas 1 and 2 by default, and signal switching unit C can The C3 end to the C5 end and the C4 end to the C6 end can be connected by default. In this way, the auxiliary Wi-Fi chip can send and receive signals through antennas 3 and 4 by default.

It can be understood that the signal switching unit AC is used to control the antennas used by the main Wi-Fi chip and the auxiliary Wi-Fi chip to send and receive signals. The embodiment of the present application does not limit the specific circuit structure of the signal switching unit AC. For example, in addition to controlling the antenna connected to the main Wi-Fi chip through the single-pole double-throw switch shown in Figure 2, the electronic device 100 can also connect a switch to the A1-A2 terminal line shown in Figure 2, and connect the A1 A switch is connected to the terminal-A3 terminal line. By controlling the connection and disconnection of these two switches, the purpose of switching the antenna connected to the main Wi-Fi chip is achieved. For another example, the main Wi-Fi chip can provide four interfaces for connecting antenna 1 to antenna 4 respectively, and control the antennas connected to the main Wi-Fi chip by controlling the connection and disconnection of the switch between the interfaces and the antennas, and , in this case, the main Wi-Fi chip can also send and receive signals through antenna 1-antenna 3, or antenna 1-antenna 4 at the same time. Therefore, embodiments of the present application do not limit the number of antennas used by the Wi-Fi chip when transmitting and receiving signals. Similarly, the embodiments of this application describe the specific circuit structure of the signal switching unit shown in Figures 3 and 4, as well as the There is no limit on the number of antennas used by the Wi-Fi chip when sending and receiving signals, so I won’t go into details below.

In addition, it should be noted that the main Wi-Fi chip can be in dual-antenna working mode by default. A preferred possibility is that when the main Wi-Fi chip switches the connected antenna, it can switch the two antennas used by the main Wi-Fi chip at the same time. Then, the switching rhythms of signal switching unit A and signal switching unit B are synchronized. The electronic device 100 can simultaneously control the signal switching unit A and connect the A1 end to the A2 end of the signal switching unit A, so that the main Wi-Fi chip uses antenna 1 and antenna 2 to send and receive signals at the same time, or the electronic device 100 can control the signal switching unit at the same time. The A1 end to A3 end of A and the B1 end to B3 end of signal switching unit B are connected, and further combined with the connection of the signal switching unit C line, the main Wi-Fi chip uses antenna 3 and antenna 4 to send and receive signals at the same time. Similarly, the main Wi-Fi chip shown in Figures 3 and 4 can also be in the dual-antenna working mode by default. The electronic device 100 can control the signal switching unit to realize that the main Wi-Fi chip uses antenna 1 and antenna 2 at the same time, or, Antenna 3 and antenna 4 send and receive signals, which will not be described in detail below. Alternatively, the main Wi-Fi chip can also send and receive signals through antenna 1 and antenna 3, or antenna 2 and antenna 4, or the main Wi-Fi chip can also send and receive signals through antenna 1 and antenna 4, or antenna 2 and antenna 3 signal, the embodiment of this application does not limit the antenna connected to the Wi-Fi chip.

As shown in FIG. 3 , the electronic device 100 may include: a processing unit, a main Wi-Fi chip, a secondary Wi-Fi chip, multiple signal switching units, and multiple antennas.

The structural schematic diagram shown in FIG. 3 is similar to the structural schematic diagram shown in FIG. 2 . The difference is that the signal switching unit C shown in FIG. 2 is replaced by the signal switching units D and E shown in FIG. 3 . Among them, the D1 terminal of the signal switching unit D is connected to the A3 terminal of the signal switching unit A, the D2 terminal of the signal switching unit D is connected to one end of the auxiliary Wi-Fi chip, the D3 terminal of the signal switching unit D is connected to the antenna 3, and the D3 terminal of the signal switching unit E is connected to the antenna 3. The E1 terminal is connected to the B3 terminal of the signal switching unit B, the E2 terminal of the signal switching unit E is connected to one end of the auxiliary Wi-Fi chip, and the E3 terminal of the signal switching unit E is connected to the antenna 4. Among them, the signal switching units D and F can be single-pole double-throw switches.

For specific descriptions of the components in Figure 3, as well as the connection conditions of components not illustrated, please refer to the relevant content of the aforementioned Figure 2, and will not be described again here.

The specific implementation process of the main Wi-Fi chip and the auxiliary Wi-Fi chip selecting the antenna to send and receive signals is described below based on the line conduction status of signal switching units A, B, D, and E respectively:

1) Signal switching unit A

Similar to the signal switching unit A in Figure 2, for the control signal input to the signal switching unit A in Figure 3, the control signal can be used to control the main Wi-Fi chip to send and receive signals through the antenna 1. The difference is that in the control signal When the A1 end of the switching unit A is connected to the A3 end, the connection of the line by the switching unit D can be further controlled by controlling the signal, so that the main Wi-Fi chip sends and receives signals through the antenna 3.

2) Signal switching unit B

Similar to the signal switching unit B in Figure 2, for the control signal input to the signal switching unit B in Figure 3, the control signal can be used to control the main Wi-Fi chip to send and receive signals through the antenna 2. The difference is that in the control signal When the B1 terminal to the B3 terminal of the control signal switching unit B are connected, the line can be further connected through the control signal switching unit E, so that the main Wi-Fi chip sends and receives signals through the antenna 4 .

3) Signal switching unit D

For the control signal input to the signal switching unit D, the control signal can be used to control the connection between the D1 end and the D3 end of the signal switching unit D (see the dotted line in the signal switching unit D shown in Figure 3). At this time, during the signal switching When the A1 end of unit A is connected to the A3 end, the main Wi-Fi chip can send and receive signals through the antenna 3; alternatively, the control signal can be used to control the connection of the D2 end to the D3 end of the signal switching unit D (see Figure 3 The solid line in the signal switching unit D), at this time, the auxiliary Wi-Fi chip can send and receive signals through the antenna 3.

4) Signal switching unit E

For the control signal input to the signal switching unit E, the control signal can be used to control the connection between the E1 end and the E3 end of the signal switching unit E (see the dotted line in the signal switching unit E shown in Figure 3). At this time, during the signal switching When the B1 end of unit B is connected to the B3 end, the main Wi-Fi chip can send and receive signals through the antenna 4; alternatively, the control signal can be used to control the connection of the E2 end to the E3 end of the signal switching unit E (see Figure 3 The solid line in the signal switching unit E), at this time, the auxiliary Wi-Fi chip can send and receive signals through the antenna 4.

Initially, signal switching unit A can connect A1 to A2 by default, and signal switching unit B can connect B1 to B2 by default. In this way, the main Wi-Fi chip can send and receive signals through antennas 1 and 2 by default, and signal switching unit D The D2 terminal can be connected to the D3 terminal by default, and the signal switching unit E can be connected to the E2 terminal to the E3 terminal by default. In this way, the auxiliary Wi-Fi chip can send and receive signals through antennas 3 and 4 by default.

As shown in FIG. 4 , the electronic device 100 may include: a processing unit, a main Wi-Fi chip, a secondary Wi-Fi chip, a signal switching unit, and multiple antennas.

Among them, the structural schematic diagram shown in Figure 4 is similar to the structural schematic diagram shown in Figure 2. One end of the main Wi-Fi chip and the auxiliary Wi-Fi chip are both The processing unit is connected. The difference is that the signal switching unit AC shown in Figure 2 is replaced by the signal switching unit F shown in Figure 4. Among them, the F1 end and F2 end of the signal switching unit F are respectively connected to the two ends of the main Wi-Fi chip, the F3 end and the F4 end are respectively connected to the two ends of the slave Wi-Fi chip, and the F5 end to the F8 end are connected to the antennas 1-4 respectively. . The signal switching unit F may be a four-pole four-throw switch.

For specific descriptions of the components in Figure 4 and the connection of components not described above, please refer to the relevant content of Figure 2, and will not be described again here.

The specific implementation process of the main Wi-Fi chip and the auxiliary Wi-Fi chip selecting the antenna to send and receive signals is described below based on the line conduction status of the signal switching unit F:

For the control signal input to the signal switching unit F, the control signal can be used to control the connection between the F1 end and the F5 end of the signal switching unit F, and the connection between the F2 end and the F6 end. At this time, the main Wi-Fi chip can pass the antenna 1 , 2 to send and receive signals; or, the control signal can be used to control the connection from the F1 end to the F7 end of the signal switching unit F, and the connection from the F2 end to the F8 end (see the dotted line in the signal switching unit F shown in Figure 4), this At this time, the main Wi-Fi chip can send and receive signals through antennas 3 and 4; in addition, the control signal can also be used to control the connection from the F3 end to the F7 end of the signal switching unit F, and the connection from the F4 end to the F8 end. At this time, The auxiliary Wi-Fi chip can send and receive signals through antennas 3 and 4.

Initially, the signal switching unit E can connect the F1 terminal to the F5 terminal, the F2 terminal to the F6 terminal, the F3 terminal to the F7 terminal, and the F4 terminal to the F8 terminal by default (see the solid line in the signal switching unit F shown in Figure 4), In this way, the main Wi-Fi chip can send and receive signals through antennas 1 and 2 by default, and the auxiliary Wi-Fi chip can send and receive signals through antennas 3 and 4 by default.

In addition, it should be noted that compared with Figures 2 and 3, the circuit structure shown in Figure 4 is simpler. Only one radio frequency switch can control the selection of antennas by the main Wi-Fi chip and the auxiliary Wi-Fi chip. Among them, compared with the main Wi-Fi chip in Figures 2 and 3, which needs to go through the loss of two radio frequency switches to send and receive signals through antennas 3 and 4, the circuit shown in Figure 4 only has the loss of one radio frequency switch. Therefore, The circuit shown in Figure 4 has little impact on the insertion loss of the RF path.

In summary, it can be seen from Figures 2 to 4 that the main Wi-Fi chip can send and receive signals through antennas 1 and 2 or antennas 3 and 4. Antennas 3 and 4 serve as backup antennas for the main Wi-Fi chip. When the Wi-Fi chip sends and receives signals through antennas 1 and 2, if the signal strength is weak, the main Wi-Fi chip can switch to antennas 3 and 4 to send and receive signals, or the main Wi-Fi chip can send and receive signals through antennas 1 and 2. On the basis of, additional antennas 3 and 4 are added to transmit and receive signals. In addition, the auxiliary Wi-Fi chip only transmits and receives signals through antennas 3 and 4. The auxiliary Wi-Fi chip can be used when the electronic device 100 is in multi-device collaboration and/or multi-network concurrency. In the scene, it enters the working state, shares the computing workload of the main Wi-Fi chip, and transmits data simultaneously through the backup antennas, namely antennas 3 and 4, to increase the speed of concurrent multi-service communication and reduce communication delays. Specific descriptions of multi-device collaboration and multi-network concurrency can be found in subsequent method embodiments, which will not be described here.

It should be understood that when the main Wi-Fi chip switches to the backup antenna to send and receive signals, the main Wi-Fi chip can only switch to one antenna. For example, when the main Wi-Fi chip sends and receives signals through antennas 1 and 2, if the signal strength is weak , then the main Wi-Fi chip can switch antenna 2 to antenna 4. At this time, the main Wi-Fi chip can send and receive signals through antennas 1 and 4. The embodiment of the present application does not limit the number of antennas switched by the Wi-Fi chip.

The following describes the process of the antenna multiplexing method provided by the embodiment of the present application.

Figure 5 shows a schematic flowchart of the antenna multiplexing method provided by the embodiment of the present application.

As shown in Figure 5, the method includes:

S101. The electronic device 100 controls the main Wi-Fi chip to send and receive signals through the main antenna.

In this embodiment of the present application, the electronic device 100 includes dual Wi-Fi chips: a primary Wi-Fi chip and a secondary Wi-Fi chip. Among them, the antenna configured by default on the main Wi-Fi chip can be called the main antenna, and the antenna configured by default on the auxiliary Wi-Fi antenna can be called a multiplex antenna. Among them, the antenna types of the main antenna and the multiplexed antenna may include but are not limited to: inverted F-shaped antenna (Inverted F-shaped Antenna, IFA antenna), planar inverted F-shaped antenna (Planar Inverted F-shaped Antenna, PIFA antenna), slot antenna Slot antenna and so on. In addition, the antenna polarization directions or patterns of the main antenna and the multiplexed antenna may be different. Preferably, the antenna polarization directions or patterns of the main antenna and the multiplexed antenna are complementary.

It can be understood that the electronic device 100 is not limited to only including two Wi-Fi chips. In other embodiments of the present application, the electronic device 100 may also include three Wi-Fi chips or four Wi-Fi chips, etc. , the embodiment of the present application does not limit the number of Wi-Fi chips included in the electronic device 100. In addition, the main antenna or the multiplexed antenna may include one or more antennas. For example, the main antenna and the multiplexed antenna may include 2 antennas.

For example, referring to Figures 2 to 4, the main antenna may refer to antennas 1 and 2, and the multiplexed antenna may refer to antennas 3 and 4.

It should be understood that the embodiments of this application do not limit the names of the main Wi-Fi chip, the auxiliary Wi-Fi chip, the main antenna, and the multiplexed antenna. The main Wi-Fi chip can also be called the original Wi-Fi chip, the first Wi-Fi chip, and the first Wi-Fi chip. -Fi chip, auxiliary Wi-Fi chip can also be called new Wi-Fi chip, second Wi-Fi chip, main antenna can also be called original antenna, first antenna, multiplexed antenna can also be called Add new antennas, second antennas, etc., The names of the above components do not constitute limitations on the role or function of the component.

Among them, the electronic device 100 can control the main Wi-Fi chip to send and receive signals through the main antenna when the Wi-Fi function needs to be used, such as browsing the web, watching videos, etc. via Wi-Fi.

Referring to Figures 2 and 3, the electronic device 100 can connect the main Wi-Fi chip to the antennas 1 and 2 by controlling the connection from the A1 end to the A2 end of the signal switching unit A, and controlling the connection from the B1 end to the B2 end of the signal switching unit B. , to achieve the purpose of the electronic device 100 controlling the main Wi-Fi chip to send and receive signals through the main antenna.

Referring to Figure 4, the electronic device 100 can connect the F1 end to the F5 end and the F2 end to the F6 end of the control signal switching unit F, so that the main Wi-Fi chip connects to the antennas 1 and 2, so that the electronic device 100 controls the main Wi-Fi chip. The purpose of the Fi chip is to send and receive signals through the main antenna.

S102. When the preset conditions are met, the electronic device 100 triggers a decision whether to switch the antenna used by the main Wi-Fi chip.

Among them, the preset conditions may include one or more of the following:

1) The signal quality of the main Wi-Fi chip when sending and receiving signals deteriorates

In this case, the electronic device 100 can monitor the signal quality of the main Wi-Fi chip when it is working, and when the signal quality of the main Wi-Fi chip is lower than the preset threshold, trigger the decision whether to switch the antenna used by the main Wi-Fi chip.

2) The folding form of the electronic device 100 changes

Due to changes in the folded form of the electronic device 100, the coverage effect of the antenna will change, affecting the signal quality when the main Wi-Fi chip is working. Therefore, when the folded form of the electronic device 100 changes, it can be triggered to determine whether to switch the antenna used by the main Wi-Fi chip.

For example, the electronic device 100 can detect the posture change of the electronic device 100 through sensor devices, such as a gyroscope sensor, an acceleration sensor, etc., and then determine the folded form of the electronic device 100 .

3) The user actively initiates a trigger operation

This trigger operation can be used to control the main Wi-Fi chip to maintain optimal quality when sending and receiving signals, or to allow the main Wi-Fi chip to switch antennas. In this case, after detecting the user's trigger operation, the electronic device 100 may trigger and determine whether to switch the antenna used by the main Wi-Fi chip in response to the operation.

4) The electronic device 100 is in a preset scene

In this preset scenario, the electronic device 100 needs to prioritize ensuring the signal quality when the main Wi-Fi chip sends and receives signals, so that the signal quality when the main Wi-Fi chip sends and receives signals through the antenna remains optimal. The preset scene may refer to the Wi-Fi communication in which the electronic device 100 executes a designated application or designated function through the main Wi-Fi chip, such as a game application, a video conferencing function, etc. The designated application or designated function may be configured by the developer in advance. The preset can also be preset by the user in advance, and the embodiments of the present application do not limit this.

For example, the preset scene may refer to a video conference scene, that is, when the electronic device 100 performs Wi-Fi communication of the video conferencing application through the main Wi-Fi chip and conducts the video conference, in order to ensure the signal quality of the video conference, the electronic device 100 may When the device 100 performs Wi-Fi communication for a video conferencing application through the main Wi-Fi chip, it determines whether to switch the antenna used by the main Wi-Fi chip.

It can be understood that the embodiments of the present application do not limit the conditions for the electronic device to trigger and determine whether to switch the antenna used by the main Wi-Fi chip.

When the preset conditions are met, the electronic device 100 can determine whether to switch the antenna used by the main Wi-Fi chip by determining whether the secondary Wi-Fi chip is in a working state. This is because the secondary Wi-Fi chip uses the multiplexed antenna to send and receive signals. When the secondary Wi-Fi chip is not in working state, the multiplexed antenna is not occupied. At this time, the main Wi-Fi chip can use the multiplexed antenna as a backup antenna. Use this multiplexed antenna to send and receive signals.

S103. The electronic device 100 determines whether the secondary Wi-Fi chip is in working state.

The electronic device 100 can control the secondary Wi-Fi chip to enter the working state in a dual Wi-Fi scenario, and control the secondary Wi-Fi chip to exit the working state when exiting the dual Wi-Fi scenario.

When the auxiliary Wi-Fi chip is in working state, specifically the auxiliary Wi-Fi chip sends and receives signals through the multiplexed antenna. For example, in the electronic device 100, the secondary Wi-Fi chip can be connected to the processor through pins, and the electronic device 100 can determine whether the secondary Wi-Fi chip is in a working state by reading information on the pins.

Among them, the dual Wi-Fi scenario may include one or more of the following:

1) Multi-device collaboration

The multi-device collaboration function is a distributed technology that can achieve cross-system and cross-device collaboration. After multiple devices are connected, resource sharing and collaborative operations can be achieved. For example, the multi-device collaboration scenario may refer to a screen casting scenario.

That is to say, the electronic device 100 can trigger the auxiliary Wi-Fi chip to enter the working state when detecting that the multi-device collaboration function is activated. Taking the multi-device collaboration scenario as a screen projection scenario as an example, when the electronic device 100 detects that the screen projection function is used, it triggers the auxiliary Wi-Fi chip to enter the working state.

FIG. 6 exemplarily shows a schematic diagram of a scenario in which the electronic device 100 uses dual Wi-Fi chips to communicate in a multi-device collaboration scenario.

As shown in Figure 6, the electronic device 100 uses the 2.4G/5G frequency band and CH36 channel to establish a Wi-Fi connection with the router through the main Wi-Fi chip, and performs Internet services such as network downloading and web browsing. At the same time, through the auxiliary Wi-Fi -Fi chip uses the 5G frequency band and CH149 channel to communicate with the electronic device 200, and then performs the screen projection service of the electronic device 100.

2) Multi-network concurrency

Multi-network concurrency means that the electronic device 100 can establish Wi-Fi connections with multiple channels of the router at the same time, enabling multiple channels to work at the same time, speeding up the data transmission rate, and improving communication quality. At this time, the electronic device 100 can connect to the two channels through the main Wi-Fi chip and the auxiliary Wi-Fi chip respectively to achieve communication in a multi-network concurrent scenario.

Generally speaking, in a multi-network concurrent scenario, the electronic device 100 can establish Wi-Fi connections with multiple routers at the same time. For a router that supports multiple channels working simultaneously, the electronic device 100 can be connected to multiple channels of the router at the same time.

Specifically, the electronic device 100 may be provided with an application whitelist. Applications in the whitelist are allowed to be used in multi-network concurrent scenarios. Then, when the electronic device 100 detects that the application in the whitelist is running, the electronic device 100 triggers the auxiliary function. The Wi-Fi chip enters the working state and realizes the data transmission of the application through multiple networks concurrently, increasing the network bandwidth and improving the network speed when users use the application.

FIG. 7 exemplarily shows a schematic diagram of a scenario in which the electronic device 100 uses dual Wi-Fi chips to communicate in a multi-network concurrent scenario.

As shown in Figure 7, the electronic device 100 can use the 5G frequency band and CH36 channel through the main Wi-Fi chip, and use the 5G frequency band and CH149 channel through the auxiliary Wi-Fi chip to communicate with the router at the same time.

That is to say, the dual Wi-Fi scenario mentioned in the embodiment of this application may refer to the electronic device 100 running a preset application and/or activating the screen casting function.

It can be understood that the auxiliary Wi-Fi chip is not limited to entering the working state in the above scenario, and the embodiment of the present application does not limit this scenario.

In addition, the electronic device 100 can periodically determine whether the secondary Wi-Fi chip is in working state. At this time, the electronic device 100 can periodically determine whether the secondary Wi-Fi chip is in use at a certain interval, so that the electronic device 100 can periodically determine whether the secondary Wi-Fi chip is in use. Determine whether it is necessary to switch the antenna connected to the main Wi-Fi chip. Alternatively, the electronic device 100 can continuously determine whether the auxiliary Wi-Fi chip is in use. At this time, the electronic device 100 can monitor the working status of the auxiliary Wi-Fi chip at all times to ensure that the electronic device 100 can operate when the auxiliary Wi-Fi chip is not working. status, the antenna connected to the main Wi-Fi chip can be adjusted in time.

In some embodiments, when the secondary Wi-Fi chip is not in working state, the electronic device 100 can further determine whether to switch the antenna used by the primary Wi-Fi chip based on the signal quality when the primary Wi-Fi chip uses different antennas.

Among them, the electronic device 100 can use a smart antenna algorithm to determine whether to switch the antenna of the main Wi-Fi chip based on the signal quality when the main Wi-Fi chip uses different antennas.

Specifically, the electronic device 100 can connect the main Wi-Fi chip to the main antenna and the multiplexed antenna respectively, and determine whether to switch the main Wi-Fi by comparing the signal quality when the main Wi-Fi chip uses the main antenna and the multiplexed antenna to send and receive data. -Antenna used by Fi chip.

The embodiments of this application do not limit the parameters used to judge signal quality.

When the electronic device 100 detects that the signal quality of the main Wi-Fi chip using the main antenna is lower than the signal quality of the main Wi-Fi chip using the multiplexed antenna, the main Wi-Fi chip switches to the multiplexed antenna to send and receive signals, that is, step S104 is performed. , otherwise, the main Wi-Fi chip does not switch the antenna, that is, it performs Go to step S105.

It can be understood that the embodiment of the present application does not limit the execution order of step S102 and step S103. When the electronic device 100 first performs step S102 and then performs step S103, at this time, the electronic device 100 can determine whether the auxiliary Wi-Fi chip is in the working state after determining that the preset conditions are met, and when it is not in the working state, switch The antenna used by the main Wi-Fi chip, or further combined with the signal quality of the main Wi-Fi chip using different antennas to send and receive signals to determine whether to switch the antenna used by the main Wi-Fi chip; or when the electronic device 100 first performs step S103, and then performs In step S102, the electronic device 100 may also first determine whether the secondary Wi-Fi chip is in the working state, and then determine whether the preset conditions are met when the secondary Wi-Fi chip is not in the working state, and switch to the primary chip when the preset conditions are met. The antenna used by the Wi-Fi chip may be further combined with the signal quality of the main Wi-Fi chip using different antennas to send and receive signals to determine whether to switch the antenna used by the main Wi-Fi chip.

S104. The electronic device 100 controls the main Wi-Fi chip to switch to transmit and receive signals through the multiplexed antenna.

When the electronic device 100 determines the antenna used by the main Wi-Fi chip based on the signal quality when using different antennas in conjunction with the main Wi-Fi chip, if the electronic device 100 determines to switch the antenna used by the main Wi-Fi chip, then the main Wi-Fi chip If the signal quality when sending and receiving signals through the multiplexed antenna is higher than the signal quality when using the main antenna to send and receive signals, the electronic device 100 can switch the antenna used by the main Wi-Fi chip and control the main Wi-Fi chip to send and receive signals through the multiplexed antenna. , ensuring that the signal quality remains optimal when the main Wi-Fi chip is working.

Referring to Figure 2, the electronic device 100 can be connected through the A1 terminal to the A3 terminal of the control signal switching unit A, the B1 terminal to the B3 terminal of the control signal switching unit B, and the C1 terminal to the C5 terminal of the control signal switching unit C. The C4 end to the C6 end of the signal switching unit C is connected, so that the main Wi-Fi chip is connected to the antennas 3 and 4, so that the electronic device 100 controls the main Wi-Fi chip to send and receive signals through the multiplexed antenna.

Referring to Figure 3, the electronic device 100 can be connected through the A1 terminal to the A3 terminal of the control signal switching unit A, the B1 terminal to the B3 terminal of the control signal switching unit B, and the D1 terminal to the D3 terminal of the control signal switching unit D. The E1 end of the control signal switching unit E is connected to the E3 end, so that the main Wi-Fi chip is connected to the antennas 3 and 4, so that the electronic device 100 controls the main Wi-Fi chip to send and receive signals through the multiplexed antenna.

Referring to Figure 4, the electronic device 100 can connect the F1 end to the F7 end and the F2 end to the F8 end of the control signal switching unit F, so that the main Wi-Fi chip connects to the antennas 3 and 4, so that the electronic device 100 controls the main Wi-Fi chip. The purpose of the Fi chip is to send and receive signals through multiplexed antennas.

Further, during the process of the main Wi-Fi chip transmitting and receiving signals through the multiplexed antenna, if the electronic device 100 enters a dual Wi-Fi scenario, that is, when the electronic device 100 needs to enable the secondary Wi-Fi chip, the electronic device 100 can control the main Wi-Fi chip. The Wi-Fi chip switches back to sending and receiving signals through the main antenna, and controls the auxiliary Wi-Fi chip to send and receive signals through the multiplexed antenna.

In addition, during the process of the main Wi-Fi chip sending and receiving signals through the multiplexed antenna, if the electronic device 100 detects that the signal quality when the main Wi-Fi chip uses the main antenna to send and receive signals is higher than that when the multiplexed antenna is used to send and receive signals. When the signal quality deteriorates, the electronic device 100 may also control the main Wi-Fi chip to switch back to receiving signals through the main antenna. For example, the electronic device 100 may trigger the detection of the main Wi-Fi chip when detecting that the folded form of the electronic device 100 changes, or detecting that the signal quality of the current main Wi-Fi chip using a multiplexed antenna to send and receive signals is lower than a threshold. Does the Fi chip need to switch antennas?

S105. The electronic device controls the main Wi-Fi chip to keep sending and receiving signals through the main antenna.

When the electronic device 100 determines the antenna used by the main Wi-Fi chip based on the signal quality when using different antennas in conjunction with the main Wi-Fi chip, if the electronic device 100 determines not to switch the antenna used by the main Wi-Fi chip, then the main Wi-Fi The signal quality when the chip sends and receives signals through the main antenna is higher than the signal quality when using the multiplexed antenna to send and receive signals. Then the electronic device 100 does not need to switch the antenna used by the main Wi-Fi chip and still controls the main Wi-Fi chip to use the main antenna. Send and receive signals to ensure the best signal quality when the main Wi-Fi chip is working.

Similarly, during the process of the main Wi-Fi chip sending and receiving signals through the main antenna, if the electronic device 100 detects that the signal quality when the main Wi-Fi chip uses the multiplexed antenna to send and receive signals is higher than when the main Wi-Fi chip uses the main antenna to send and receive signals. When the signal quality is low and the auxiliary Wi-Fi chip is not working, the electronic device 100 can also control the main Wi-Fi chip to switch to receive signals through the multiplexed antenna. For example, the electronic device 100 may trigger the detection of the main Wi-Fi when detecting that the folded form of the electronic device 100 changes, or detecting that the signal quality of the current main Wi-Fi chip using the main antenna to send and receive signals is lower than a threshold. Does the chip need to switch antennas?

It can be understood that when the electronic device 100 determines that the secondary Wi-Fi chip is not in a working state, it can directly use the main antenna to send and receive signals without judging whether to switch the antenna used by the main Wi-Fi chip. On the top, a new multiplexed antenna is added to simultaneously send and receive signals, that is, the number of antennas used by the main Wi-Fi chip is increased when working, and the signal quality when the main Wi-Fi chip is sending and receiving signals is increased.

In general, the antenna multiplexing method provided by the embodiments of this application multiplexes the smart antenna required by the main Wi-Fi chip with the antenna configured by the auxiliary Wi-Fi chip, so that the multiplexed antennas, such as antenna 3, 4 can be used as an antenna for the main Wi-Fi chip or as an antenna for the auxiliary Wi-Fi chip, which reduces the number of antennas that need to be configured on the electronic device 100 and avoids increasing the complexity of the manufacturing process when there are too many antennas. complexity, and at the same time, under the configuration of dual Wi-Fi chips, it can reduce the delay of concurrent multi-services and improve communication efficiency. Moreover, it fully considers the signal loss of the antenna in different folding forms of the device, avoiding the problem of device failure. After changing the folding form, the communication signal becomes weaker or even interrupted, which improves the user experience.
