In this embodiment, the method for adjusting the antenna scanning direction may be applied to a millimeter wave communication system, and when the electronic device accesses the millimeter wave communication system, a beam of a millimeter wave antenna on the electronic device may be aligned with an antenna beam of a millimeter wave base station, so as to ensure that the communication quality of the electronic device reaches an optimal state. Since the electronic device is a portable mobile device, a user may not stay in place all the time, and when the position of the user changes, the beam direction of the millimeter wave antenna on the electronic device may deviate from the original direction, which may result in a decrease in communication quality. In order to solve the technical problem, the embodiment provides a method for adjusting the scanning direction of the antenna, and after the electronic device generates displacement, the scanning direction of the millimeter wave antenna module can still rapidly face the millimeter wave base station, so that the response speed of beam tracking is effectively improved, and the communication quality is guaranteed.
Specifically, referring to fig. 2, fig. 2 is a schematic flowchart illustrating a method for adjusting an antenna scanning direction according to an embodiment of the present application, where the method includes:
step 201, monitoring displacement information of the electronic device, and determining whether the electronic device needs to perform beam adjustment according to the displacement information.
In this embodiment, the moving direction and distance of the electronic device within a preset time period may be monitored by a preset acceleration sensor in the electronic device, so as to obtain displacement information of the electronic device. The change of the positioning point of the electronic equipment in a preset time period can be monitored through a positioning system preset by the electronic equipment, so that the displacement information of the electronic equipment is obtained. The positioning system is more suitable for a scene where the electronic device moves at a high speed, for example, when a user takes a high-speed rail, the positioning system is more accurate in acquiring displacement information of the electronic device.
Further, after the displacement information of the electronic device is monitored, whether the electronic device needs to perform beam adjustment can be judged by judging whether the displacement information meets a preset beam adjustment condition.
Step 202, when the electronic device needs to perform beam adjustment, acquiring an initial beam direction of the millimeter wave antenna module before the electronic device generates displacement.
In this embodiment, before the default electronic device generates the displacement, the initial beam direction of the millimeter wave antenna module is the better beam direction. When the beam adjustment is needed, the initial beam direction of the electronic device before the displacement is generated can be used as a reference direction.
Step 203, determining a beam adjustment direction corresponding to the millimeter wave antenna module according to the displacement information and the initial beam direction, and adjusting the scanning direction of the millimeter wave antenna module based on the determined beam adjustment direction.
In this embodiment, the displacement direction of the electronic device may be determined based on the displacement information, and then, based on the displacement direction and the initial beam direction, it may be determined whether the beam direction of the millimeter wave antenna module of the electronic device has deviated from the initial beam direction, if so, a beam adjustment direction corresponding to the millimeter wave antenna module may be determined according to the displacement information and the initial beam direction, and the scanning direction of the millimeter wave antenna module may be adjusted based on the determined beam adjustment direction, so as to quickly adjust the beam direction of the millimeter wave antenna module of the electronic device to a better direction.
The method for adjusting the scanning direction of the antenna provided by the embodiment of the application comprises the steps that when the electronic equipment is connected with a millimeter wave base station, whether the electronic equipment needs to perform beam adjustment or not is judged through displacement information of the electronic equipment, if yes, the beam adjustment direction corresponding to the millimeter wave antenna module is determined according to the displacement information of the electronic equipment and the initial beam direction of the electronic equipment, so that the scanning direction of the millimeter wave antenna module is adjusted in time, after the electronic equipment generates displacement, the scanning direction of the millimeter wave antenna module can still face the millimeter wave base station, the response speed of beam tracking can be effectively improved, and the communication quality is effectively guaranteed.
Further, based on the foregoing embodiment, in the embodiment of the present application, the determining whether the electronic device needs to perform beam adjustment according to the displacement information in step 201 includes:
determining whether the displacement distance of the electronic equipment in a preset time period is greater than a preset distance threshold, and determining that the electronic equipment needs to perform beam adjustment when the displacement distance of the electronic equipment in the preset time period is greater than the preset distance threshold.
It can be understood that, when the electronic device is greatly displaced in a short time, if the beam pointing direction of the millimeter wave antenna module of the electronic device is not adjusted in time, the communication quality of the electronic device may be affected. Therefore, in order to ensure better communication quality after the electronic device has a large displacement within a short time, the present embodiment determines that the electronic device needs to perform beam adjustment when the displacement of the electronic device within a preset time period is greater than a preset displacement threshold.
In addition, in this embodiment, Signal Strength information of the electronic device, such as RSSI (Received Signal Strength Indication) may also be obtained. Determining whether the descending amplitude of the signal intensity of the electronic equipment in a preset time period is larger than a preset amplitude threshold value or not, and determining that the electronic equipment needs to perform beam adjustment when the descending amplitude of the signal intensity of the electronic equipment in the preset time period is larger than the preset amplitude threshold value.
It can be understood that, when the drop amplitude of the signal strength of the electronic device in the preset time period is greater than a preset amplitude threshold (e.g., 50%), it may also be indicated that the beam pointing direction of the millimeter wave antenna module of the electronic device is not adjusted in time, and it may also be determined that the electronic device needs to perform beam adjustment.
Further, based on the foregoing embodiment, referring to fig. 3, fig. 3 is another schematic flow chart of a method for adjusting an antenna scanning direction in the embodiment of the present application, where the method for adjusting an antenna scanning direction in the embodiment of the present application includes:
step 301, determining whether a signal strength indication parameter corresponding to the electronic device is greater than a preset strength threshold.
And step 302, when the signal intensity indication parameter is greater than a preset intensity threshold, acquiring antenna scanning angle information corresponding to the millimeter wave antenna module and coordinate information of a plane where the millimeter wave antenna module is located.
In this embodiment, before monitoring displacement information or signal strength information of the electronic device, it is determined whether a signal strength indication parameter corresponding to the electronic device is greater than a preset strength threshold, that is, it is determined whether an initial beam direction of the millimeter wave antenna module of the electronic device is a better direction.
The antenna scanning angle information corresponding to the millimeter wave antenna module and the coordinate information of the plane where the millimeter wave antenna module is located can be obtained in the following manner:
a. and establishing a spherical coordinate system by using the millimeter wave antenna module as an origin.
b. Determining a first coordinate of an antenna scanning direction of the millimeter wave antenna module in the spherical coordinate system, and acquiring the first coordinate as the antenna scanning angle information;
c. and determining the direction of the normal of the plane where the millimeter wave antenna module is located by using the orientation sensing assembly, and acquiring a second coordinate in the spherical coordinate system by using the second coordinate as the coordinate information of the plane where the millimeter wave antenna module is located.
Wherein, a spherical coordinate system (r, theta) is established by using the millimeter wave antenna module as the origin0,
Figure BDA0002071490120000101
) Then, a first coordinate (thetaant) of the antenna scanning direction of the millimeter wave antenna module in the spherical coordinate system is obtained0，
Figure BDA0002071490120000102
)。
The installation plane of the millimeter wave antenna module in the electronic equipment can be predetermined, if the plane of the millimeter wave antenna module can be parallel to the plane of the display screen of the electronic equipment, the orientation of the display screen of the electronic equipment is determined by the orientation sensing component, the direction of the normal of the plane of the millimeter wave antenna module can be determined, and then the second coordinate (theta) is obtainedp0,
Figure BDA0002071490120000103
)。
The direction sensing module may be specifically composed of a gravity sensor (or an acceleration sensor), a direction sensor (or an electronic compass), and the like.
And step 303, determining and storing the initial beam direction of the millimeter wave antenna module before the electronic equipment generates the displacement based on the antenna scanning angle and the coordinate information.
For example, if the display screen of the electronic device is horizontally disposed, the plane where the millimeter wave antenna module is located is parallel to the display screen of the electronic device, and the antenna scanning direction of the millimeter wave antenna module is vertical to the plane where the millimeter wave antenna module is located, the finally determined initial beam direction of the millimeter wave antenna module is also vertical.
And step 304, monitoring the displacement information or the signal intensity information of the electronic equipment, and judging whether the electronic equipment needs to perform beam adjustment according to the displacement information or the signal intensity information.
Step 305, when the electronic device needs to perform beam adjustment, acquiring an initial beam direction of the millimeter wave antenna module before the electronic device generates displacement.
Step 306, determining a beam adjustment direction corresponding to the millimeter wave antenna module according to the displacement information and the initial beam direction, and adjusting the scanning direction of the millimeter wave antenna module based on the determined beam adjustment direction.
The contents described in the above steps 304 to 306 are the same as the contents described in the above steps 201 to 203 in the above embodiment, and specific reference may be made to the description in the above embodiment, which is not repeated herein.
According to the method for adjusting the antenna scanning direction, when the signal intensity indicating parameter corresponding to the electronic equipment is determined to be larger than the preset intensity threshold value, the initial beam direction of the millimeter wave antenna module is obtained and stored. When the electronic equipment is generating displacement, whether the electronic equipment needs to perform beam adjustment or not is judged through the displacement information or the signal intensity information of the electronic equipment, if so, the beam adjustment direction corresponding to the millimeter wave antenna module is determined according to the displacement information of the electronic equipment and the initial beam direction of the electronic equipment, so that the scanning direction of the millimeter wave antenna module is adjusted in time, after the electronic equipment generates displacement, the scanning direction of the millimeter wave antenna module still can face the millimeter wave base station, the response speed of beam tracking can be effectively improved, and the communication quality is effectively guaranteed.
Further, based on the foregoing embodiment, referring to fig. 4, fig. 4 is a schematic sub-flow diagram of a method for adjusting an antenna scanning direction in the embodiment of the present application, in which the step of determining a beam adjustment direction corresponding to the millimeter wave antenna module according to the displacement information and the initial beam direction in the embodiment of the present application includes:
step 401, determining a moving direction of the electronic equipment based on the displacement information;
step 402, determining a beam adjusting direction corresponding to the millimeter wave antenna module based on a change condition of an included angle between the moving direction and the initial beam direction.
Specifically, when the size of the included angle between the moving direction of the electronic device and the initial beam direction is in a trend of increasing, the beam adjusting direction corresponding to the millimeter wave antenna module should be opposite to the initial beam direction, and when the size of the included angle between the moving direction of the electronic device and the initial beam direction is in a trend of decreasing, the beam adjusting direction corresponding to the millimeter wave antenna module should still be the same as the initial beam direction.
For better understanding of the embodiment of the present invention, referring to fig. 5, fig. 5 is a schematic view of an application scenario of the method for adjusting the antenna scanning direction in the embodiment of the present invention.
