Example 1:
as shown in fig. 1, this embodiment provides a deployment method of an intelligent super surface RIS, including:
and step 101, obtaining the opening angle of the angle ruler according to the incident angle and the emergent angle.
IN this embodiment, as shown IN fig. 2, the incident angle and the exit angle of the RIS are constrained as follows, and the normal line of the RIS points to the IN0RE0 point when viewed from the top, the line pointing to IN30 indicates that the incident angle is 30 degrees, and the line pointing to RE60 indicates that the exit angle after reflection of the RIS is 60 degrees. The devices that complete the RIS deployment are shown in FIG. 3, including a base station, mobile station, angle gauge, laser level, or infrared level. A laser level meter or an infrared level meter (the laser/infrared level meter is used as a reference in the figure and is not limited to the form and the style) is respectively arranged at the base station (transmitter) side and the mobile station (receiver) side, the two laser/infrared level meters are positioned at the same horizontal plane, the laser/infrared level meters at the base station side and the mobile station side adopt beams with different colors, for example, the laser level meter at the base station side emits red beams, the laser level meter at the mobile station side emits green beams, and the RIS panel is convenient to quickly adjust and deploy by adopting the beams with different colors; the angle rule is deployed at the position to be installed in the RIS (the angle rule is taken as a reference in the figure, and is not limited to the form and style), wherein the angle rule can adopt a single angle measurement angle rule (the angle rule shown in fig. 3) or can adopt a double angle measurement angle rule (namely, the angle rule has three sides and can simultaneously measure two angles). In order to improve the performance of the RIS, accurate installation of the RIS is required, and in this embodiment, two methods of measuring an angle rule based on single angle measurement and a double angle measurement angle rule and a deployment method of the RIS using a laser level meter are used as examples.
Single angle measurement based angle scale deployment RIS:
specifically, acquiring the opening angle of the angle gauge according to the incident angle and the exit angle includes:
the opening angles of the first angle ruler and the second angle ruler are obtained according to the incidence angle and the emergence angle: the opening angle of the first angle ruler is equal to the sum of the incident angle and the emergent angle; the opening angle of the second angle ruler is equal to the difference between the right angle and the incident angle; the first angle ruler and the second angle ruler are angle rulers for single-angle measurement.
In this embodiment, as shown in fig. 4, the center point of the antenna panel of the base station and the center point of the antenna panel of the mobile station are located at the same height, and the two antenna panels are disposed perpendicular to the ground. And a laser/infrared level meter is respectively arranged right above the centers of the antenna panels of the base station and the mobile station. The laser/infrared level meter emits a vertical linear beam, wherein the vertical linear beam is adopted to avoid the influence on the accuracy of RIS deployment due to the fact that the center points of the antenna panels of the base station and the mobile station are not completely at the same height. As shown in fig. 4, two angles are deployed, the angle α is the first angle, and the angle θ is the second angle. The opening angles of the first angle ruler and the second angle ruler meet the following calculation formula:
θ＝90°-λ (1)
α＝λ+δ (2)
where λ is the incident angle, δ is the exit angle, and the incident angle and the exit angle are known.
Step 102, setting a first beam emitted by the base station side laser level meter to coincide with a first edge of an opening angle of the angle gauge, and setting a second beam emitted by the mobile station side laser level meter to coincide with a second edge of the opening angle of the angle gauge, wherein the first beam and the second beam are vertical straight beams.
In this embodiment, as shown in fig. 4, a first beam emitted from the base station side is set to coincide with a first edge of the first angle ruler, and a second beam emitted from the mobile station side is set to coincide with a second edge of the first angle ruler.
Optionally, after the obtaining the opening angle of the angle gauge according to the incident angle and the exit angle and before the setting the first beam emitted by the base station side laser level to coincide with the first edge of the opening angle of the angle gauge, the deployment method of the intelligent super-surface RIS further includes: disposing a first angle ruler and a second angle ruler according to the opening angle, wherein the fixed point positions of the first angle ruler and the second angle ruler are not overlapped; the first edge of the opening angle of the first angle ruler is overlapped with the second edge of the opening angle of the second angle ruler.
In this embodiment, if the known incident angle is 30 degrees, the exit angle is 45 degrees, and the opening angle of the first angle ruler is 75 degrees and the opening angle of the second angle ruler is 60 degrees according to the formula (1) and the formula (2). The first edge of the first angle ruler is set to coincide with the second edge of the second angle ruler, the first angle ruler and the second angle ruler are rapidly deployed according to the obtained opening angle, as shown in fig. 4, the fixed point of the first angle ruler is set as X, and the fixed point positions of the two angle rulers are not coincident.
Step 103, disposing the RIS on the first side of the angle ruler, and adjusting the RIS panel to enable the first beam and the second beam on the RIS panel to coincide.
In this embodiment, the RIS or the center point of the RIS is disposed on the first side of the first angle ruler, and adjusting the RIS panel includes moving the RIS panel along the extension line along which the first side is located, or adjusting the angle of the RIS panel, and so on.
Specifically, the disposing the RIS on the first side of the angle ruler, and adjusting the RIS panel to make the first beam and the second beam on the RIS panel coincide, specifically includes: setting RIS center point and antenna panel center point of base station and mobile station to be at same height; deploying the RIS panel parallel to the first side of the opening angle of the second angle scale; and adjusting the position of the RIS panel on an extension line of the opening angle of the first angle ruler so as to enable the first beam and the second beam on the RIS panel to coincide.
In this embodiment, since the first angle ruler and the second angle ruler have been deployed quickly according to the opening angle, the RIS panel is deployed in parallel with the first edge of the second angle ruler, and the position of the RIS panel is adjusted along the extension line of the first edge of the first angle ruler until the first beam and the second beam on the RIS panel overlap. The adjustment of the RIS panel can be quickly realized, namely, the installation position of the RIS panel can be quickly determined. Preferably, the center point of the RIS is arranged on the extension line of the first edge of the first angle ruler, the RIS is parallel to the first edge of the second angle ruler, the center point of the RIS is moved along the first edge of the first angle ruler, and when the first beam and the second beam on the RIS panel are overlapped, the installation position of the RIS is reasonable and accurate.
Optionally, before the first beam emitted by the laser level at the base station side is overlapped with the first edge of the opening angle of the angle gauge, the deployment method of the intelligent super-surface RIS further includes: and arranging antenna panels of the base station and the mobile station perpendicular to the ground, and setting the central points of the antenna panels of the base station and the mobile station to be at the same height.
In this embodiment, by disposing the base station, the mobile station, and the center point of the RIS at the same height, the accuracy of the RIS disposition can be improved, thereby improving the RIS performance.
Preferably, when α=λ+δ=90°, the ground feature characteristics may be fully utilized, the first angle ruler is omitted, the characteristic that the tile angle is 90 ° is proportionally utilized, the second edge of the second angle ruler coincides with one edge of the tile, and the beam emitted by the laser/infrared level on the mobile station side coincides with the corresponding vertical edge of the tile. It should be noted that the angle ruler may be disposed directly below the to-be-deployed position of the RIS and have a preset distance z from the center point of the RIS (e.g., the angle ruler is deployed on the ground), in other words, the angle ruler may be at a different height from the RIS/base station/mobile station. When the RIS deployment position is determined, two angle scales can be arranged on the ground, so that the risk of climbing a building with a high height by personnel is avoided, the RIS deployment method is more convenient to implement, and the RIS deployment position is more convenient to determine.
Angle rule deployment RIS based on double angle measurement:
the step of obtaining the opening angle of the angle ruler according to the incident angle and the emergent angle specifically comprises the following steps: acquiring a first opening angle of the angle gauge, wherein the first opening angle is equal to the difference between the right angle and the incident angle; acquiring a second opening angle of the angle ruler, wherein the second opening angle is equal to the sum of the right angle and the emergence angle; acquiring a third opening angle of the angle ruler, wherein the third opening angle is equal to the sum of the incident angle and the emergent angle; wherein, the angle ruler is a double-angle measurement angle ruler.
In this embodiment, as shown in fig. 5, the angle ruler for double angle measurement has three sides, wherein a first opening angle θ is formed by a first side and a third side of the angle ruler, a second opening angle γ is formed by a first side and a second side of the angle ruler, and a third opening angle β is formed by a second side and a third side of the angle ruler. Three opening angles of the angle gauge are determined according to the following formula (3) -formula (5):
θ＝90°-λ (3)
β＝90°+δ (4)
γ＝λ+δ (5)
optionally, after the obtaining the opening angle of the angle gauge according to the incident angle and the exit angle and before the setting the first beam emitted by the base station side laser level to coincide with the first edge of the opening angle of the angle gauge, the RIS deployment method further includes: and deploying the angle ruler according to the first opening angle, the second opening angle and the third opening angle, wherein the fixed point position X of the angle ruler.
Optionally, the disposing the RIS on the first side of the angle ruler, and adjusting the RIS panel to make the first beam and the second beam on the RIS panel coincide, specifically includes: setting RIS center point and antenna panel center point of base station and mobile station to be at same height; the RIS panel is deployed to be parallel to the third side of the angle ruler; and adjusting the position of the RIS panel on the extension line of the first edge of the angle ruler so as to enable the first beam and the second beam on the RIS panel to coincide.
In this embodiment, according to the angle rule that can rapidly deploy the dual angle measurement according to the three opening angles, by deploying the RIS panel parallel to the third edge of the dual angle measurement angle rule, the position of the RIS panel is adjusted on the extension line of the first edge of the dual angle measurement angle rule until the first beam and the second beam on the RIS panel coincide, so that the adjustment of the RIS panel can be rapidly implemented, that is, the installation position of the RIS panel can be rapidly determined, and the RIS can convert the incident wave with the incident angle λ into the emergent wave with the emergent angle δ, so that the emergent beam is focused on the mobile station, thereby establishing a good communication path based on the reflection path of the RIS. Preferably, the center point of the RIS is arranged on the extension line of the first edge of the angle ruler, the RIS is parallel to the third edge of the angle ruler, the RIS center point is moved along the first edge of the angle ruler, and when the first beam and the second beam on the RIS panel are overlapped, the installation position of the RIS is reasonable and accurate.
According to the deployment method of the intelligent super-surface RIS, the opening angle of the angle gauge is determined through the known incident angle and the known emergent angle, the beam emitted by the base station side laser level meter and the beam emitted by the mobile station side laser level meter are respectively overlapped with the two sides of the angle gauge, the RIS is rapidly deployed on the first side of the angle gauge, the panel is adjusted, the two beams received on the RIS panel are overlapped, and then the RIS deployment is completed. The deployment method improves the installation efficiency of the RIS and ensures the installation accuracy at the same time, thereby improving the performance of the RIS. Further, the laser/infrared level gauges at the base station side and the mobile station side adopt beams of different colors, so that the RIS panel can be conveniently and quickly adjusted and deployed. The beam emitted by the laser level meter adopts a vertical straight beam, so that the influence on the accuracy of RIS deployment caused by the fact that the central points of the antenna panels of the base station and the mobile station are not completely at the same height can be avoided. In addition, the angle ruler can be arranged right below the RIS to-be-deployed position, and a preset distance z exists between the angle ruler and the RIS center point (for example, the angle ruler is deployed on the ground), in other words, the angle ruler, the RIS, the base station and the mobile station can be at different heights. When the RIS deployment position is determined, two angle scales can be arranged on the ground, so that the risk of climbing a building with a high height by personnel is avoided, the RIS deployment method is more convenient to implement, and the RIS deployment position is more convenient to determine. The embodiment can complete the deployment of RIS based on the angle ruler for single angle measurement or the angle ruler tool for double angle measurement, the deployment tool is simple, and the deployment method is convenient to implement.

For example, a red beam line represents a plane from the connection terminal and the RIS, a green beam line represents a plane connecting the base station and the RIS, where the two planes meet, indicating that the beam from the base station impinges on the RIS and exits from the RIS to the terminal, and if it meets elsewhere, is not reflected by the RIS.
