Background
Electromagnetic waves in the millimeter wave band enable high-speed data transmission, and for example, 5G is a millimeter wave that implements the 802.11AY standard in the 60Ghz band. However, due to the characteristics of millimeter waves, the directivity and the reflectivity of millimeter waves are strong, so that a great number of propagation paths are generated in an indoor environment, and the most effective propagation path among the generated propagation paths is a direct-view path in which an electronic device is directly aligned with a wireless access point (AP, hereinafter referred to as AP), and the transmission efficiency of data can be greatly improved through the direct-view path.
At present, the method of finding a direct-view path is to calculate the efficiency of all propagation paths one by one, and the path with the highest propagation efficiency found by calculation is taken as the direct-view path; however, the propagation paths are many, which results in a very large and complex calculation amount for the electronic device to search for the AP, and the calculation amount is too heavy for the battery of the electronic device, which may seriously reduce the propagation rate of the signal; in addition, for an electronic device moving at any time, the environment changes at any time, which causes the formed propagation path to change continuously, and thus the task of searching for the AP cannot be implemented.

In the embodiment shown in fig. 2, the first type of sensors includes a first sensor, a second sensor, a third sensor, a fourth sensor and a fifth sensor, and the angle information of each sensor is respectively determined, for example, the angle information of the first sensor is + x, the angle information of the second sensor is + y, the angle information of the third sensor is + y, the angle information of the fourth sensor is + z, and the angle information of the fifth sensor is-y, then, the three sensors with the normal directions perpendicular to each other in pairs can be the first sensor, the fourth sensor and the second sensor, and can be the first sensor, the fourth sensor and the third sensor; there may also be a first sensor, a fourth sensor and a fifth sensor.

In this embodiment, another specific method for determining three sensors with two perpendicular normal directions from the first type of sensors is provided, and specifically, the three sensors with two perpendicular normal directions are first grouped and stored, for example, when the angle information of the first sensor is set to + x, the angle information of the second sensor is set to-Z, the angle information of the third sensor is set to + y, the angle information of the fourth sensor is set to-x, the angle information of the fifth sensor is set to + Z, and the angle information of the sixth sensor is set to-y, at this time, the first sensor, the second sensor and the third sensor may be grouped, the first sensor, the second sensor and the sixth sensor may be grouped, and the first sensor, the third sensor and the fifth sensor may be grouped, it is also possible to group the second sensor, the third sensor and the fourth sensor, etc. Any three sensors with two perpendicular normal directions can be used as a group. When the first type of sensors includes the first sensor, the second sensor, the third sensor, the fourth sensor and the fifth sensor, three sensors that have been stored in a group form are selected as three sensors whose normal directions are respectively two-by-two perpendicular, for example, since the first sensor, the second sensor and the third sensor have been stored as a group, the first sensor, the second sensor and the third sensor may be selected from the first type of sensors as three sensors whose normal directions are respectively two-by-two perpendicular.
In another embodiment provided by the invention, when the selected three sensors are not unique, the user can be prompted to select, and the selection can also be randomly selected based on the needs calculated by the first electronic device. For example, continuing with the above embodiment, when the first type of sensor includes the first sensor, the second sensor, the third sensor, the fourth sensor and the fifth sensor, the first sensor, the second sensor and the third sensor may be selected from the first type of sensor as three sensors with two-by-two perpendicular normal directions, or the first sensor, the third sensor and the fifth sensor may be selected from the first type of sensor as three sensors with two-by-two perpendicular normal directions, where the three selected sensors are not unique, and at this time, the user may be prompted to select one group for subsequent calculation, or may randomly select the first sensor based on the calculation requirement of the first electronic device.
In one embodiment of the present invention, as shown in fig. 2, the specific step of obtaining the first angle information and the second angle information based on the optical intensity values of the first sensor, the second sensor and the fourth sensor, which are perpendicular to each other in the normal direction, is that the optical intensity value of the first sensor is represented by I1The optical intensity value of the second sensor is denoted by I2The optical intensity value of the fourth sensor is denoted by I3If so, the first angle information is:
the second angle information is:
the derivation process of the first angle information and the second angle information is specifically described below:
for each sensor, the incident light intensity reaching the sensor is: where Gr is the receive gain, T is the source intensity, H is the path gain, where H is calculated by the Lambertian radiation pattern,
where A is the sensor area, g is the optical condenser coefficient, Ψ is the arrival angle of the sensor, m is the Lambert order, γ is the incident angle, i.e., the angle between the light source-sensor vector and the normal vector of the light source surface, and ρ is the distance between the light source and the sensor.
The optical intensity for each sensor shown in fig. 2 is:
wherein j is a subscript indicating a different sensor when j is a different number; c is a sensor-related parameter, pjIs the distance of the sensor and the light source;
wherein the vector P is the position vector of the light source, the vector PjIs the position vector of the sensor, vector z is the unit vector, and vector μ j is the unit vector.
Since the distance between the sensors is much smaller than the distance from the sensor to the light source, the ratio of the light intensities of two adjacent sensors is only the sumAngle of arrival correlation, i.e.
For quadrature sensors, cos (ψ)2)＝sin(90-ψ1) To obtain
For three sensors with two perpendicular normal directions, the first angle information can be obtained as follows:

According to the steps, a first path for the first electronic device to communicate with the second electronic device can be determined.
In other embodiments provided by the present invention, the method further comprises,
