Based on the foregoing embodiments, an embodiment of the present application provides an antenna control method, which is shown in fig. 2 and includes the following steps:
In the embodiment of the present application, as shown in fig. 3a and 3b, the electronic device may control the UWB communication module to radiate a first communication signal outwards, and at the same time, the UWB communication module continues to receive a feedback signal for the first communication signal, which is returned by other devices; if the UWB communication module receives the feedback signal, the electronic equipment determines that the target equipment exists within a certain distance range from the electronic equipment.
Wherein the target position is at least used to indicate a direction relative to the electronic device.
In embodiments of the present application, the target location may include a target direction; when the electronic equipment determines that the target equipment exists in a certain distance range from the electronic equipment based on the feedback signal, the target direction of the target equipment relative to the electronic equipment can be calculated according to the return signal.
In an achievable angle-measuring positioning scenario, as shown in fig. 4, the electronic device determines an azimuth angle of the target device relative to itself based on the characteristics that the electronic device is a signal transmitter and the target device is a signal receiver when the UWB communication module measures the angle. As shown in fig. 4, the electronic device may send a first communication signal to the target device, and the radiation module of the target device may send different feedback signals to two radiation modules of the electronic device at a certain time interval after receiving the first communication signal; when the electronic device receives a feedback signal transmitted by a target device through the first radiation antenna a and the second radiation antenna B, the electronic device may measure phases of the feedback signal received by the first radiation antenna a and the second radiation antenna B through a UWB communication module, so as to calculate a Phase difference of arrival (PDOA). Further, a path difference p between the radiation antenna T of the target device and the first radiation antenna a and the second radiation antenna B of the electronic device is obtained by the arrival phase difference PDOA, and then the arrival angle θ (that is, the azimuth angle of the target device with respect to the electronic device) is calculated by a (trigonometric) functional relationship according to the path difference p and the specific distance d. Specifically, it can be obtained by the following formula:
and 203, the electronic equipment determines an antenna with the directional gain corresponding to the target position as a target antenna based on the directional gains of the plurality of antennas connected with the Wi-Fi communication module on the electronic equipment.
In the embodiment of the application, an antenna with the directivity gain matched with a target position can be determined from a plurality of antennas corresponding to the Wi-Fi communication module as a target antenna according to the directivity gain of each antenna corresponding to the Wi-Fi communication module; it should be noted that the directional gain of the antenna matched with the target position may be optimal among all antennas corresponding to the Wi-Fi communication module.

In the embodiment of the application, the target position may further represent a target distance between the target device and the electronic device; at this time, the target operating power of the target antenna may be obtained based on the signal strength of the target device determined with respect to the target distance from the electronic device.
In one possible implementation scenario, as shown in fig. 3a and 3b, there may be one information interaction or multiple information interactions between the electronic device and the target device to determine a distance of the target device relative to the electronic device; as shown in fig. 3a, if there may be one information interaction between the electronic device and the target device, the electronic device may transmit a first communication signal to the target device once, the target device transmits a feedback signal to the electronic device after receiving the first communication signal, after receiving the feedback signal, the electronic device determines a time period T1 from transmitting the first communication signal to receiving the feedback signal by the electronic device, and determines a time period T2 from receiving the first communication signal to transmitting the feedback signal by the target device, where the first communication signal is electrically connected to the target deviceTransmission time T between a child device and a target devicepropCan be represented by formula
To be determined. As shown in fig. 3b, if there may be two times of information interaction between the electronic device and the target device, the electronic device may transmit the first communication signal to the target device twice, the target device transmits the first feedback signal to the electronic device after receiving the first communication signal transmitted for the first time, and after receiving the first feedback signal, after the interval time length T5, the electronic device transmits the first communication signal to the target device for the second time, the target device transmits the feedback signal for the second time after receiving the first communication signal transmitted for the second time after the interval time T6, the time length T3 from the time when the electronic device transmits the first communication signal for the first time to the time when the electronic device receives the first feedback signal for the first time is determined, and the target device determines a time period T4 from the reception of the first communication signal to the transmission of the first feedback signal, when the first communication signal is transmitted between the electronic device and the target device.propCan be represented by formula
And (4) calculating. Determining a transmission time T of a first communication signal between an electronic device and a target devicepropThen, it can be based on the transmission TpropThe transmission speed determines a target distance of the target device relative to the electronic device.
The step 205 of obtaining, by the electronic device, the target operating power of the target antenna may be implemented by:
step 205a, the electronic device determines a target signal strength matching the target position based on the distance indicated by the target position and the target correspondence between the distance and the signal strength.
In the embodiment of the present application, the target correspondence between distances and signal strengths may be determined in advance according to a large amount of test data, which refers to the correspondence between different distances and signal strengths. After the target distance of the target device relative to the electronic device is determined, the corresponding signal strength at the secondary target distance may be determined from the target correspondence between the distance and the signal strength based on the target distance as the target signal strength.
And step 205b, the electronic device adjusts the radiation power of the target antenna of the electronic device to be the target working power based on the target signal strength.
In the embodiment of the present application, the determined target signal strength matching the target distance may be a corresponding signal strength in an operating state of the antenna with the optimal performance; that is, the strength of the communication signal required by the target device at this time is the target signal strength; based on the method, the radiation power of the target antenna corresponding to the Wi-Fi communication module can be adjusted to be the target working power, namely the target antenna can transmit signals at the target working power, so that the Wi-Fi communication module of the electronic equipment can radiate strong signals, the power consumption of the Wi-Fi communication module is prevented from being overlarge, the service life of the Wi-Fi communication module is greatly prolonged, and the standby time of the electronic equipment is prolonged.
According to the antenna control method provided by the embodiment of the application, when the target equipment is determined to exist through the ultra-wideband communication module in the electronic equipment, the target position of the target equipment relative to the electronic equipment can be determined, the target antenna of the electronic equipment corresponding to the target position is determined, and then the Wi-Fi communication module is controlled to radiate communication signals based on the target antenna without scanning signal threshold values, so that the problems that a large amount of time is needed for determining an optimal antenna radiation scheme in the relative technology, and the accuracy of results cannot be guaranteed are solved, the working efficiency of the antenna is improved, and the strength of the communication signals radiated by the antenna is guaranteed.
Based on the foregoing embodiments, another embodiment of the present application provides an antenna control method, which, as shown in fig. 5, may include the following steps:
Wherein the target position is at least used to indicate a direction relative to the electronic device.
It should be noted that, after step 302, step 303 or step 304 may be executed;
In this embodiment of the application, the first operating mode may refer to an operating mode when only one antenna connected to the Wi-Fi communication module is provided, and the first operating mode may specifically refer to a Wireless Fidelity Single Input Single Output (WiFi-SISO) mode. At this time, because only one antenna is connected with the Wi-Fi communication module, the electronic device needs to use its WAN main set antenna or WAN diversity antenna as the antenna corresponding to the Wi-Fi communication module; namely, an antenna with the directional gain corresponding to the target position can be selected as a target antenna from one antenna and a WAN main set antenna which are connected with the Wi-Fi communication module; or selecting an antenna with the directional gain corresponding to the target position from one antenna and the WAN diversity antenna connected with the Wi-Fi communication module as the target antenna. Based on this, the WiFi-1T2R function can be realized; because the determined target antenna is embodied by matching the directional gain and the target position, and the target antenna can be selected from the two antennas, compared with the prior art that only one fixed antenna can be adopted to transmit a Wi-Fi signal, the receiving performance of the Wi-Fi communication module is improved.
And 304, if the Wi-Fi communication module is in the second working mode and multiplexes the WAN main set antenna and the WAN diversity antenna, the electronic equipment determines an antenna with the directional gain corresponding to the target position as the target antenna from the directional gains corresponding to the two antennas connected with the Wi-Fi communication module, the WAN main set antenna and the WAN diversity antenna.
In this embodiment of the application, the second operating mode may refer to an operating mode when two antennas connected to the Wi-Fi communication module exist, and the second operating mode may specifically refer to a Wireless Fidelity Multiple Input Multiple Output (WiFi-MIMO) mode. At this time, because there are two antennas connected to the Wi-Fi communication module, the electronic device needs to use its WAN main set antenna and WAN diversity antenna as antennas corresponding to the Wi-Fi communication module; that is, an antenna having a directional gain corresponding to a target position may be selected as a target antenna from the two antennas connected to the Wi-Fi communication module, the WAN main set antenna, and the WAN diversity antenna. Based on the method, the WiFi-1T4R/WiFi-2T4R function can be realized; because the determined target antenna is embodied by matching the directional gain and the target position, and the target antenna can be selected from the four antennas, compared with the prior art that Wi-Fi signals can be transmitted only based on two antennas, the receiving performance of the Wi-Fi communication module is greatly improved. Wherein the scheme of determining the target antenna provided in steps 303 and 304 can be applied to the mobile phone side.
It should be noted that step 305 may be executed after step 303 and step 304.
And 307, the electronic equipment adjusts the radiation power of a target antenna of the electronic equipment to be target working power based on the target signal strength.
In the embodiment of the application, the ultra-wideband communication module continuously monitors whether the obtained feedback signal of the first communication signal meets a new target device of a target condition along with the movement of the electronic device.
The target condition refers to a device which can perform Wi-Fi communication with the electronic device within a certain distance range from the electronic device. The electronic device is not fixed but is moving, and the ultra-wideband communication module can continuously monitor the feedback signal aiming at the first communication signal during the movement of the electronic device and determine that the electronic device is a new target device which can meet the target condition.
In the embodiment of the application, the ultra-wideband communication module continuously monitors the obtained feedback signal of the first communication signal along with the movement of the electronic device to determine the distance and/or the angle to the target device, so as to adjust the target working power of the target antenna in real time.
During the movement of the electronic device, the UWB communication module may continuously determine the distance and/or angle of the target device relative to the electronic device by using the method shown in the above embodiment, so as to adjust the target operating power of the target antenna in real time according to the determined changed distance and/or angle; therefore, no matter what kind of moving state the electronic equipment is in, the target antenna corresponding to the UWB communication module can be ensured to radiate the communication signal at the target working power matched with the following distance and/or the angle, the communication quality of the electronic equipment is ensured, and meanwhile, the power consumption of the Wi-Fi communication module is prevented from being overlarge.
Based on the foregoing embodiment, in other embodiments of the present application, the method may further include the following step, where the implementation scheme corresponding to steps 308 to 310 may be applied to a fifth generation mobile communication technology (5 generation mobile networks, 5G) base station.
The power adjustable range refers to an adjustable range which is specified in the 5G base station and can adjust the power of the Wi-Fi communication module; of course, the power adjustable range may be a smaller range for fine-tuning the power of the Wi-Fi communication module.
In the embodiment of the application, the reference power corresponding to the target signal strength matched with the target position can be determined, and then the target power is determined based on the power adjustable range and the reference power; that is to say, the target signal strength matched with the target angle and/or the target distance may be determined, then the reference power may be determined from the corresponding relationship between the signal strength and the power based on the target signal strength, and finally the target working power may be obtained by fine-tuning the current working power within the power adjustable range on the basis of the reference power and the current working power of the antenna of the Wi-Fi communication module.
And 310, the electronic equipment adjusts the radiation power of a target antenna of the electronic equipment to be target working power based on the target direction.
In the embodiment of the application, the radiation direction of the target antenna can be adjusted to be the target radiation direction matched with the target direction, the radiation power of the target antenna is adjusted to be the target working power, and finally the target antenna is controlled to radiate the communication signal in the target radiation direction and the target power to communicate with the target device. It should be noted that, in the embodiment of the present application, a target antenna may be determined from antennas corresponding to Wi-Fi communication modules of a 5G base station on the 5G base station based on a relative distance and/or an angle between the 5G base station and the target device, and then the target antenna is adopted to radiate a communication signal in a target radiation direction and a target power, so that the communication quality between the target device and the 5G base station is ensured, and meanwhile, the situation that the power consumption of the 5G base station is too large is avoided.
It should be noted that steps 306 to 307 and steps 308 to 310 may be executed simultaneously or separately, but steps 306 to 307 and steps 308 to 310 are not executed sequentially; that is, steps 306 to 307 may be performed after step 305, and steps 308 to 310 may also be performed.
According to the antenna control method provided by the embodiment of the application, when the target equipment is determined to exist through the ultra-wideband communication module in the electronic equipment, the target position of the target equipment relative to the electronic equipment can be determined, the target antenna of the electronic equipment corresponding to the target position is determined, and then the Wi-Fi communication module is controlled to radiate communication signals based on the target antenna without scanning signal threshold values, so that the problems that a large amount of time is needed for determining an optimal antenna radiation scheme in the relative technology, and the accuracy of results cannot be guaranteed are solved, the working efficiency of the antenna is improved, and the strength of the communication signals radiated by the antenna is guaranteed.
