[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] This application provides an electronic device; please refer to [link / reference]. Figure 1 This is a schematic diagram of the structure of the electronic device, which may include multiple antennas, multiple first feeding circuits, second feeding circuits, and a controller.

[0036] Among them, multiple antennas are the same antennas and operate at the same frequency in the same frequency band.

[0037] For example, multiple antennas can operate in the n78 band, which is required to support sub-6G.

[0038] The number of antennas mentioned above can be related to the operating frequency band. For example, the sub-6 GHz frequency band generally requires electronic devices to meet the multiple-input multiple-output (MIMO) function of 4 antennas. Therefore, the above multiple antennas may include 4 antennas operating in the sub-6 GHz frequency band.

[0039] Multiple first feed circuits, each first feed circuit being connected to one of the multiple antennas.

[0040] The second feed circuit is connected to multiple antennas.

[0041] The controller is configured to control each of the plurality of antennas to transmit and receive radio frequency signals via a first feeding circuit for each of the plurality of antennas, if in a first operating mode; and to control each of the plurality of antennas to transmit and receive radio frequency signals via a second feeding circuit, if in a second operating mode.

[0042] The number of antennas is unlimited. As an example, multiple antennas may include, for example, Figure 1 The four antennas shown correspond to four first feed circuits, each of which is connected to one of the multiple antennas.

[0043] In the first operating mode, each of the multiple antennas transmits and receives signals under the control of the first feeding circuit connected to the antenna. The different first feeding circuits are independent of each other, so in the first operating mode, the multiple antennas transmit and receive radio frequency signals independently.

[0044] The first operating mode mentioned above can be a multiple input multiple output (MIMO) mode. In this mode, the electronic device can establish multiple channels with the base station through multiple independently operating antennas. Each antenna is used to receive radio frequency signals on its own channel. As a result, the number of channels between the electronic device and the base station is significantly increased, thereby increasing the communication rate between the electronic device and the base station.

[0045] In the second operating mode, multiple antennas operate under the control of the same feed circuit, meaning they are all connected to the same feed circuit. Therefore, the electronic device can uniformly control the signal transmission and reception of multiple antennas through the second feed circuit, enabling them to function as an array antenna and thus meeting the needs of specific scenarios where a single antenna operating independently cannot fulfill the requirements.

[0046] The beneficial effects of this embodiment are as follows:

[0047] Multiple antennas operating in the same frequency band are connected to the same second feeding circuit. Thus, the controller can control the multiple antennas to transmit and receive radio frequency signals in a unified manner through the second feeding circuit in the second operating mode, so that the multiple antennas can work as an array antenna, thereby meeting the needs that a single antenna working independently cannot meet in some scenarios.

[0048] In some alternative embodiments, the controller can control multiple antennas to switch between a first operating mode and a second operating mode based on arbitrary conditions. As an example, the controller can switch between the first operating mode and the second operating mode based on at least one of the following conditions:

[0049] Condition 1: The controller is used to switch from the first operating mode to the second operating mode if the received power through each of the multiple antennas is below a threshold while in the first operating mode.

[0050] In condition one, the controller can obtain the power of the signal provided by each first feed circuit as the received power of the antenna corresponding to that first feed circuit.

[0051] Condition 2: If the controller is in the first operating mode, it is configured to switch from the first operating mode to the second operating mode in response to the first switching command.

[0052] The first switching command is used to instruct the activation of the second operating mode. The first switching command can be manually entered by the user or generated by the controller based on the usage scenario of the electronic device. For example, the controller can generate the first switching command when the electronic device switches from a video application to a calling application.

[0053] Condition 3: The controller is used to switch from the second operating mode to the first operating mode if the received power through multiple antennas is higher than a threshold while in the second operating mode.

[0054] The controller can obtain the total power of the radio frequency signals received by multiple antennas from the second feed circuit and use the total power as the received power of the multiple antennas. The threshold of condition three can be the same as or different from the threshold of condition one; for example, the threshold of condition three can be higher than the threshold of condition one.

[0055] Condition 4: If the controller is in the second operating mode, it is configured to switch from the second operating mode to the first operating mode in response to a second switching instruction.

[0056] The second switching command is used to instruct the activation of the first operating mode. The second switching command can be manually entered by the user or generated by the controller based on the usage scenario of the electronic device. For example, the controller can generate the second switching command when the electronic device switches from a call application to a video application.

[0057] The initial mode of multiple antennas, that is, the operating mode when multiple antennas start working, can be determined as follows.

[0058] Optionally, when multiple antennas start working, such as when an electronic device is powered on, the controller can control the multiple antennas to be in a default working mode. The default working mode can be either the first working mode or the second working mode.

[0059] Optionally, when multiple antennas start working, the controller can also control the multiple antennas to be in a first working mode or a second working mode according to the current usage scenario of the electronic device. For example, if the electronic device is running a video application, the controller controls the multiple antennas to be in the first working mode; if the electronic device is not running a video application, the controller controls the multiple antennas to be in the second working mode.

[0060] Optionally, when multiple antennas start working, the controller can also control the multiple antennas to be in the first working mode or the second working mode according to the user's operation.

[0061] Switching from the first operating mode to the second operating mode can be achieved by the controller disconnecting the connection between each first feed circuit and its corresponding antenna, and connecting the second feed circuit and each antenna; switching from the second operating mode to the first operating mode can be achieved by connecting the connection between each first feed circuit and its corresponding antenna, and disconnecting the connection between the second feed circuit and each antenna.

[0062] Switching from the first operating mode to the second operating mode can also be achieved by the controller controlling each first power supply circuit to power off, that is, controlling the first power supply circuit to disconnect from the power supply of the electronic device, and controlling the second power supply circuit to power on, that is, controlling the second power supply circuit to connect to the power supply of the electronic device; or switching from the second operating mode to the first operating mode can also be achieved by the controller controlling each first power supply circuit to power on and controlling the second power supply circuit to power off.

[0063] The second feeder circuit can have various structures. (Combined) Figure 1 In the example of four antennas, the second feed circuit can have, for example, Figure 2 The structure shown.

[0064] The second power supply circuit includes multiple phase shifters, multiple power dividers, and a signal transceiver component (T / R component).

[0065] One end of each phase shifter is connected to an antenna, for example Figure 2 In the middle, phase shifter 1 is connected to the first antenna on the left, phase shifter 2 is connected to the second antenna, phase shifter 3 is connected to the third antenna, and phase shifter 4 is connected to the fourth antenna.

[0066] Each phase shifter is connected to a power divider at the other end. Each power divider can input two signals and combine them into one signal for output, or it can input one signal and decompose the input signal into two signals for output. Multiple power dividers can combine the signals output from multiple phase shifters into one signal for the T / R component, or they can decompose the signal from the T / R component into multiple signals and provide each signal to a phase shifter. In this way, the electronic device can uniformly control multiple antennas to work as an array antenna.

[0067] It needs to be explained that, Figure 2 In the second feed circuit shown, the phase shifter can be replaced with other devices capable of adjusting the phase of the input RF signal to a specified output phase, that is, other phase adjustment devices, not limited to... Figure 2 The phase shifter shown.

[0068] When multiple antennas are in the second operating mode, the controller can control the multiple antennas to transmit and receive radio frequency signals in any of the following control methods:

[0069] Control method one: If in the second working mode, configure the second feeding circuit based on the first target parameters so that the array antenna composed of multiple antennas is in a gain state.

[0070] Control method two: If in the second working mode, configure the second feeding circuit based on the second target parameters so that the array antenna composed of multiple antennas is in the scanning state.

[0071] Control method three: If in the second working mode, configure the second feeding circuit based on the second target parameters so that the array antenna composed of multiple antennas is in the scanning state. After determining the target phase in the scanning state, configure the second feeding circuit based on the first target parameters so that the array antenna composed of multiple antennas is in the gain state.

[0072] Taking a phase shifter as an example, please refer to [link to relevant documentation]. Figure 3 In this embodiment, each phase shifter of the second power supply circuit can be connected to the phase shifter control circuit set in the controller. The phase shifter control circuit can configure the target parameters of each phase shifter, thereby controlling the phase shifter to be in a specific phase.

[0073] In control mode one, the controller can control the phase adjustment device connected to each of the multiple antennas in the second feed circuit to be in the target phase. In this case, multiple antennas can transmit and receive radio frequency signals in the same frequency band, the same frequency, and the same phase. That is, multiple antennas receive radio frequency signals from the same channel. This can improve the signal power of the radio frequency signals transmitted and received on the channel, thereby solving the problem that the signal power of each antenna is low when multiple antennas work independently, which affects the smoothness of communication.

[0074] When a phase adjustment device is at the target phase, it means that the output phase of the phase adjustment device is the target phase. For example, when a phase adjustment device is controlled to be at the target phase of 30°, the phase adjustment device can adjust the phase of the input radio frequency signal to 30°, and then output a radio frequency signal with the adjusted phase of 30°.

[0075] Depending on the control method of the phase adjustment device, the first target parameter can be different.

[0076] As an example, when the phase adjustment device is a phase shifter, the phase shifter can control the output phase of the phase shifter by inputting a specific control current. Therefore, the first target parameter for controlling the phase shifter can be the first current parameter corresponding to the target phase.

[0077] In control mode one, the controller can determine the target phase in multiple ways.

[0078] One way to determine the target phase is to determine the phase of the antenna with the highest received power among the multiple antennas if the received power of each of the multiple antennas is below a threshold when the first operating mode is in operation.

[0079] In this determination method, the controller can first detect the power of the signal provided by each first feed circuit to obtain the received power of each antenna, determine the target antenna with the highest received power, and then determine the phase of the target antenna as the target phase.

[0080] The phase of the antenna refers to the phase of the feed signal provided to the antenna by the feed circuit connected to the antenna. The feed signal provided to the antenna by the feed circuit is used to control the antenna to transmit and receive radio frequency signals.

[0081] Another way to determine the target phase is to obtain a phase setting command and determine the phase specified in the command as the target phase. The phase setting command can be determined by the controller in response to the operation of the electronic device user. For example, if the user selects a target phase of 30°, the controller obtains a phase setting command specifying 30° as the target phase based on the operation.

[0082] Another way to determine the target phase is for the controller to determine the target phase based on the communication between the electronic device and the base station. For example, the base station can send a correspondence between phase and signal power to the controller. This correspondence is used to indicate the signal power of the radio frequency signal transmitted by the base station on different phases. The controller determines the target phase based on this correspondence, for example, determining the phase with the largest corresponding signal power as the target phase.

[0083] In control method two, the controller can configure different second target parameters for each phase adjustment device in the second feed circuit. This allows the phase adjustment devices connected to each of the multiple antennas in the second feed circuit to be in different phases. Consequently, the electronic device can scan the array antennas to obtain information about radio frequency signals in different phases.

[0084] In control mode two, the controller can first determine what phase each phase adjustment device needs to be in, then determine the second target parameter corresponding to the phase adjustment device based on the phase it needs to be in, and finally configure each second target parameter to the corresponding phase adjustment device.

[0085] The phase to which each phase adjustment device is to be located can be determined based on the scanning phase range and the number of phase adjustment devices.

[0086] For example, the controller can divide the scanning phase range into multiple equal-length phase intervals according to the number of phase adjustment devices, and set the upper limit of each phase interval as the phase that a phase adjustment device should be in.

[0087] The scanning phase range can be a default parameter, or it can be determined based on the phase of each antenna in the first operating mode. For example, the maximum and minimum phase values ​​of multiple antennas in the first operating mode can be determined as the upper and lower limits of the scanning phase range.

[0088] Combination Figure 3 For example, assuming the scanning phase range is 0° to 120°, the controller can divide this range into four equal-length phase intervals according to the number of phase shifters (4): 0° to 30°, 30° to 60°, 60° to 90°, and 90° to 120°. The upper limit of each interval is determined as the phase that the phase shifter needs to be in. That is, it is determined that phase shifter 1 needs to be in the 30° phase, phase shifter 2 needs to be in the 60° phase, phase shifter 3 needs to be in the 90° phase, and phase shifter 4 needs to be in the 120° phase.

[0089] Then, the controller determines the control current corresponding to the above four phases, and finally configures the control current corresponding to the 30° phase, the 60° phase, the 90° phase, and the 120° phase in sequence for phase shifters 1 to 4 through the phase shifter control circuit, so that phase shifters 1 to 4 are respectively in the above phases.

[0090] In control mode three, the controller first controls the array antenna composed of multiple antennas to be in scanning mode to determine the target phase, and then controls the array antenna composed of multiple antennas to be in gain mode.

[0091] The controller can determine the target phase in the scanning state in the following ways:

[0092] If in the second operating mode, the second feeding circuit is configured based on the second target parameters so that the array antenna composed of multiple antennas is in a scanning state, so as to obtain the phase corresponding to the antenna with the best signal in the array antenna as the target phase.

[0093] In this embodiment, the phase corresponding to the antenna with the best signal in the array antenna refers to the phase of the phase adjustment device connected to the antenna with the best signal among the multiple antennas constituting the array antenna.

[0094] When the array antennas are in scanning mode, the controller can determine the quality index of the signal received by each antenna and identify the antenna with the best corresponding quality index as the antenna with the best signal. "Best corresponding quality index" can mean either the highest or the lowest corresponding quality index.

[0095] The controller can determine any attribute of the signal as a quality indicator, including but not limited to the signal-to-noise ratio and received power.

[0096] As an example, determine the received power of the signal received by each antenna, and identify the antenna with the highest received power as the antenna with the best signal.

[0097] When multiple antennas operate as an array antenna, the received power of each antenna can be determined as follows:

[0098] The T / R module obtains multiple signals from multiple antennas through a power divider, analyzes these signals to determine which antenna receives each signal, and then detects the signal power of each signal to determine the received power of the antenna receiving that signal.

[0099] One way to determine which antenna receives each signal is:

[0100] When each phase adjustment device processes the signal received by its connected antenna, it adds information that identifies the phase adjustment device to the signal. After the T / R component obtains a signal, it analyzes the signal to obtain the information that identifies the phase adjustment device, thereby determining which phase adjustment device provides the signal. Then, through the pre-configured correspondence between phase adjustment devices and antennas, it determines which antenna receives the signal.

[0101] Based on the previous example, in control mode three, the controller controls the array antenna to operate in a scanning state. At this time, it is assumed that phase shifters 1 to 4 are configured to be at 30°, 60°, 90° and 120° respectively. Then the controller finds that the signal of the antenna connected to phase shifter 1 is the best, so it determines the phase of 30° where phase shifter 1 is located as the target phase. Then the controller configures phase shifters 1 to 4 according to the first target parameter corresponding to the target phase of 30°, so that phase shifters 1 to 4 are all at the target phase of 30°.

[0102] The beneficial effect of this embodiment is that it can find the target phase corresponding to the best signal in signals of different phases, and then control the array antenna to receive the signal with the target phase in the gain state, thereby improving the quality of the signal received by the electronic device and ensuring that the electronic device can communicate through radio frequency signals when the electronic device is in a weak field environment with poor signal.

[0103] In this embodiment, the multiple antennas can have the same shape. These antennas can have various shapes. As an example, each of the multiple antennas can have... Figure 4 The shape shown.

[0104] Multiple antennas can be mounted on the inside of the back panel of an electronic device. These antennas can be positioned at different locations on the back panel. For example, when multiple antennas include four antennas, the four antennas can be positioned on the left and right sides or the top and bottom sides of the back panel, with two antennas on each side; alternatively, the four antennas can be positioned near the four vertices of the back panel; or, the four antennas can be arranged as follows: Figure 5 The arrangement shown is such that the panels are placed side by side on the right side (or left side, top side, etc.) of the back panel.

[0105] The first and second power supply circuits can be installed on the printed circuit board (PCB) of the electronic device.

[0106] The spacing between any two antennas in a multi-antenna system is no less than the target distance. This target distance can be determined based on the frequency bands in which the antennas operate. For example, the target distance can be equal to half the target wavelength corresponding to the frequency band in which the antennas operate. The target wavelength corresponding to the frequency band refers to the wavelength corresponding to the center frequency of that frequency band.

[0107] This application also provides a signal transmission and reception method; please refer to [link to relevant documentation]. Figure 6 Here is a flowchart of the method, which may include the following steps.

[0108] S601 determines the operating mode of multiple antennas, where the multiple antennas are the same antennas and operate at the same frequency in the same frequency band.

[0109] In S601, the controller can determine the operating mode when multiple antennas start working in the manner described above for determining the initial mode, or it can control multiple antennas to switch to another operating mode in the manner described above for switching when the antennas are already in a certain operating mode.

[0110] S602, if in the first working mode, multiple antennas are controlled to transmit and receive radio frequency signals through multiple first feeding circuits respectively; each first feeding circuit is connected to one of the multiple antennas.

[0111] S603, if in the second operating mode, controls each of the multiple antennas to transmit and receive radio frequency signals through the second power supply circuit, which is connected to the multiple antennas.

[0112] It should be noted that S602 and S603 are not sequential; that is, multiple antennas of an electronic device can be in the first working mode first and then switch to the second working mode, or they can be in the second working mode first and then switch to the first working mode.

[0113] Optionally, the method further includes:

[0114] If the received power of each of the multiple antennas is below the threshold in the first operating mode, switch from the first operating mode to the second operating mode.

[0120] The phase adjustment device connected to each of the multiple antennas in the second feed circuit is controlled to be in the target phase. The phase adjustment device is used to adjust the phase of the input radio frequency signal to the specified output phase.

[0121] Optionally, the method may also include one of the following:

[0122] If in the first working mode, the phase of the antenna with the highest received power among the multiple antennas is determined as the target phase because the received power of each of the multiple antennas is lower than the threshold.

[0123] If in the second operating mode, the second feeding circuit is configured based on the second target parameters so that the array antenna composed of multiple antennas is in a scanning state, so as to obtain the phase corresponding to the antenna with the best signal in the array antenna as the target phase.

[0124] Optionally, configuring the second feed circuit based on the second target parameters includes:

[0125] The phase adjustment device connected to each of the multiple antennas in the second feed circuit is controlled to be in a different phase. The phase adjustment device is used to adjust the phase of the input radio frequency signal to a specified output phase.
