[0002] With the development of the fifth generation mobile communication technology (5G), 5G technology is gradually being fully commercialized. 5G technology can greatly improve the rate and bandwidth of wireless communication, reduce data transmission delay, and provide faster and better mobile communication services for enterprises and individuals. In the existing technology, 5G base station wireless signals are sent and received through plate antennas.

[0003] However, due to the higher operating frequency of 5G wireless signals and greater spatial loss in signal propagation, the coverage range of 5G wireless signals is small, especially in linear coverage scenarios of transportation routes such as high-speed railways, motor vehicles, and highways.

[0046] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0047] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0048] The application scenarios of the embodiments of the present application are explained below:

[0049] Figure 1 An application scenario diagram of the Luneburg lens antenna shaping control method provided in the embodiment of the present application, such as Figure 1As shown, the Luneburg lens antenna provided in the embodiment of the present application is installed as a base station antenna on a 5G base station. The 5G base station is set near the high-speed rail track to provide 5G wireless signal coverage for the high-speed rail.

[0050] In the prior art, plate antennas are a common antenna form in communication networks, using multiple antenna arrays to amplify signals. The horizontal radiation pattern of the plate antenna is a fan-shaped symmetrical structure, with a large gain within the horizontal angle of ±60 degrees; outside the ±60-degree direction, the antenna gain is reduced by 10dB, and the gain is relatively low. Taking the linear coverage scenario as an example, the maximum gain of the 8TR antenna service beam is 21dBi in the 0-degree direction in front; but as the beam shifts, the gain decreases rapidly, and the gain drops to 16-18dBi at the edge of the coverage. The above defects of the traditional plate antenna lead to the degradation of 5G signal quality at the edge of the sector coverage area.

[0051] At the same time, since the horizontal beam width of the plate antenna is 65 degrees, there is no coverage in the area between 65 degrees and 90 degrees, and there is a signal blind spot. The 5G network frequency is in the Sub6GHz band, mainly in the 3.5GHz and 2.6GHz bands, and the wireless signal coverage capability is greatly reduced compared to the 1.8GHz and 2.1GHz bands used by the existing 2 / 3 / 4G. The high-frequency characteristics of the 5G network lead to serious signal path loss. The single antenna coverage range of the plate antenna is small. Designed according to the 5G user uplink rate of 200Mbps (theoretical value), the coverage radius of the 5G base station in the 3.5GHz band is only 250 meters. The base station density must be increased by 3 to 4 times the existing number to meet the continuous coverage requirements. Taking the high-speed rail coverage scenario as an example, due to high-speed movement and large carriage penetration loss, under the condition of 500-meter station spacing, the user rate of 5G network in the 3.5GHz frequency band can only reach 1-2Mbps upstream and 50Mbps downstream, which will seriously affect the user experience of using the 5G network. Further encryption of 5G base stations will cause a sharp increase in base station construction costs, bringing huge economic pressure to operators.

[0052] Figure 2 This is a structural schematic diagram of a Luneburg lens antenna provided in an embodiment of the present application. The Luneburg lens antenna provided in this embodiment includes:

[0053] Luneburg lens, Luneburg lens is a dielectric sphere, column or other geometric shape with a dielectric constant gradually changing from 2 to 1 from the inside to the outside, and Luneburg lens includes a receiving end and a transmitting end. Multiple vibrator units are arranged on the receiving end side of the Luneburg lens, and base station signal sources with different powers are fed to the vibrator units through a distributor, so that the vibrator units transmit narrow beams with different powers to the target coverage area through the Luneburg lens, forming a wide beam covering the target coverage area. Exemplarily, the vibrator unit transmits a signal from the receiving end of the Luneburg lens, which converges to form a narrow beam after refraction inside the Luneburg lens and is emitted from the transmitting end of the Luneburg lens. It should be pointed out that the narrowband beam has a corresponding radiation angle, and the size of the radiation angle is related to the radius of the Luneburg lens and the length of the vibrator unit. The larger the length of the vibrator unit and the smaller the radius of the Luneburg lens, the larger the radiation angle of the corresponding narrow beam, that is, the larger the beam width of the narrow beam.

[0054] Figure 3 A flowchart of a Luneburg lens antenna shaping control method provided in an embodiment of the present application can be applied to Figure 2 The Luneburg lens antenna shown in Figure 3 As shown, the Luneburg lens antenna shaping control method provided in this embodiment includes the following steps:

[0055] Step S101, obtaining coverage area information, where the coverage area information is used to indicate the positional relationship between the target coverage area of ​​the Luneburg lens antenna and the Luneburg lens antenna.

[0056] Exemplarily, after a wide beam formed by multiple narrow beams is transmitted to a target area, a corresponding signal coverage area is formed, namely the target coverage area. The target coverage area can be set as needed. For example, when signal coverage is required for a railway through which a train passes, the target coverage area is the strip area through which the railway passes.

[0057] Furthermore, the coverage area information is parameter information for indicating the positional relationship between the target coverage area of ​​the Luneburg lens antenna and the Luneburg lens antenna. Specifically, the coverage area information is, for example, the position coordinates of the target coverage area, the distance and orientation between the target coverage area and the Luneburg lens antenna, etc. The coverage area information may be configuration information preset in the controller of the Luneburg lens antenna; it may also be configuration information configured into the controller of the Luneburg lens antenna by a user through a terminal device connected to the Luneburg lens antenna for communication, or it may be configuration information sent to the controller of the Luneburg lens antenna by a server connected to the Luneburg lens antenna for communication; it may also be determined by the Luneburg lens antenna after collecting environmental information and processing it, which is not specifically limited here.

[0058] Step S102, determining the shaping parameters of the Luneburg lens antenna according to the coverage area information, wherein the shaping parameters are used to control the vibrator unit to transmit narrow beams with different powers to multiple positions in the target coverage area respectively, to form a wide beam covering the target coverage area.

[0059] Figure 4 A schematic diagram of a vibrator unit transmitting a narrow beam to a target coverage area provided in an embodiment of the present application. Exemplarily, the target coverage area indicated by the coverage area information includes multiple location areas, such as Figure 4 As shown, it includes position area a, position area b, and position area c. According to the positional relationship between position area a, position area b, and position area c represented by the coverage area information and the Luneburg lens antenna, the shaping parameters of the Luneburg lens antenna, such as the transmission power and incident angle of different vibrator units, can be determined. After the Luneburg lens antenna is shaped by the shaping parameters, the narrow beam emitted by vibrator unit A with the first power can cover position area a, the narrow beam emitted by vibrator unit B with the second power can cover position area b, and the narrow beam emitted by vibrator unit C with the third power can cover position area c.

[0060] Step S103, beamforming is performed on the Luneburg lens antenna according to the shaping parameters, so that the wide beam has uniform signal strength at different locations in the target coverage area.

[0061] Exemplarily, after the Luneburg lens antenna is beam-shaped according to the above-mentioned shaping parameters, each vibrator unit moves according to the shaping parameters, adjusts the incident angle of each vibrator unit to the Luneburg lens, and transmits a narrow beam with a transmission power corresponding to different positions in the target coverage area. Since the narrow beam emitted by each vibrator unit is gradually attenuated with increasing distance after being emitted to the outside world, exemplarily, the closer the position is to the Luneburg lens antenna, the smaller the corresponding transmission power; the farther the position is from the Luneburg lens antenna, the greater the corresponding transmission power, thereby adjusting the problem of uneven signal coverage intensity at different positions in the target coverage area caused by signal attenuation.

[0062] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0063] In this embodiment, by acquiring coverage area information, the coverage area information is used to indicate the positional relationship between the target coverage area of ​​the Luneburg lens antenna and the Luneburg lens antenna; according to the coverage area information, the shaping parameters of the Luneburg lens antenna are determined, wherein the shaping parameters are used to control the vibrator unit to transmit narrow beams with different powers to multiple positions of the target coverage area, respectively, to form a wide beam covering the target coverage area; according to the shaping parameters, the Luneburg lens antenna is beam-shaped so that the wide beam has uniform signal strength at different positions of the target coverage area. Since beam-forming is performed according to the shaping parameters corresponding to the target coverage area, the antenna can transmit beams of different powers to different positions within the target coverage area, thereby achieving uniform signal strength in different areas within the signal coverage area, avoiding the problem of uneven signal coverage, and improving signal coverage efficiency, thereby reducing the number of base stations and reducing the overall cost of network construction.

[0064] Figure 5 A flowchart of a Luneburg lens antenna shaping control method provided by another embodiment of the present application is shown in FIG. Figure 5 As shown, the Luneburg lens antenna shaping control method provided in this embodiment is Figure 3 On the basis of the Luneburg lens antenna shaping control method provided in the illustrated embodiment, step S101 and step S102 are further refined, and the Luneburg lens antenna shaping control method provided in this embodiment includes the following steps:

[0065] Step S201, obtaining environmental information, and determining coverage area information according to the environmental information.

[0066] Exemplarily, the environmental information is used to characterize the environmental location characteristics of the location of the Luneburg lens antenna, for example, the height of the Luneburg lens antenna from the ground, the distance of the Luneburg lens antenna from the target coverage area, for example, the distance of the Luneburg lens antenna from the roof and bottom of a high-speed train; and whether there are obstacles between the Luneburg lens antenna and the target coverage area that affect signal coverage. Further, the environmental information can be obtained by an image acquisition unit provided on the Luneburg lens antenna, or uploaded by other test equipment that communicates with the Luneburg lens antenna, or directly input by a user, which is not specifically limited here.

[0067] Furthermore, the specific positional relationship between the Luneburg lens antenna and the target coverage area can be determined based on the environmental information, for example, the coordinates corresponding to the Luneburg lens antenna and the coordinates corresponding to different positions of the target coverage area in the same virtual coordinate system.

[0068] The following is a more specific example of a process for obtaining coverage area information. Figure 6 A schematic diagram of a process for determining coverage area information provided in an embodiment of the present application, referring to Figure 6In the application scenario of high-speed rail signal coverage, the Luneburg lens antenna is located on the side of the railway, covering a distance of the railway. Assume that the projection distance of the Luneburg lens antenna on the ground is D, the height of the carriage is H, and the height difference between the Luneburg lens antenna hanging height and the carriage is H T The effective coverage distance of the Luneburg lens antenna is S, A is the far end of the car, and B is the near end of the car; and assume that H <H T <<D<<S. The angle between the beam of the antenna covering the near side of the car and the beam of the antenna covering the far side of the car is the horizontal angle θ that the antenna needs to cover. The line connecting the center of the Luneburg lens and the vertex of the car near the car is approximately one side of θ, and the line connecting the center of the sphere and the vertex of the car far away is approximately the other side of θ. β1 and β2 are the vertical angles that the Luneburg lens antenna needs to cover at the near end point and the far end point of the car respectively. Since the starting point of the car is directly in front of the antenna and the vehicle's driving direction is perpendicular to the forward direction of the antenna radiation, the horizontal angle θ is determined according to formula (1):

[0069]

[0070] Furthermore, the maximum propagation distance Lp1 of the signal emitted by the Luneburg lens antenna to the carriage, that is, the OA segment distance, is as shown in formula (2):

[0071]

[0072] The minimum propagation distance Lp2 of the signal transmitted by the Luneburg lens antenna to the carriage, that is, the OB segment distance, is shown in formula (3):

[0073]

[0074] Step S202, determining distance information according to the coverage area information, wherein the distance information is used to characterize the transmission distance between the Luneburg lens antenna and multiple locations within the target coverage area.

[0075] Exemplarily, in the target coverage area, different positions have different distances from the Luneburg lens antenna. In order to have the same signal strength at different positions, different vibrator units in the Luneburg lens antenna are required to determine the corresponding transmission power according to the transmission distance between the Luneburg lens antenna and different positions of the target coverage area. Exemplarily, the distance information can be a specific value recorded in the coverage area information, or it can be a value calculated based on the coordinates of the Luneburg lens antenna recorded in the coverage area information and the coordinates of different positions of the target coverage area, which is not specifically limited here.

[0076] Optionally, before or after step S202, the method further includes:

[0077] Step S202A, determining attenuation information based on the coverage area information, wherein the attenuation information is used to characterize signal attenuation caused by obstructions between the Luneburg lens antenna and multiple locations within the target coverage area.

[0078] Step S202B, determining a power correction value according to the attenuation information.

[0079] Figure 7 A schematic diagram of a signal coverage scenario provided for an embodiment of the present disclosure, in which the Luneburg lens antenna is used to cover the high-speed rail line. In the process of providing signal coverage to the target coverage area, there is a metal obstruction between the Luneburg lens antenna and the target coverage area that affects the transmission of electromagnetic waves. The obstruction will block the narrow beam emitted by the vibrator unit, thereby affecting the signal coverage strength at the corresponding position. Exemplarily, the coverage area information includes attenuation information characterizing the signal attenuation caused by the obstruction. For example, the obstruction will cause a -3dB attenuation. Then, according to the preset power correction information, the corresponding power correction value is determined, for example, 4dB, that is, the power is increased by 4dB.

[0080] Exemplarily, the attenuation information includes a signal attenuation rate. In one possible implementation, if the signal attenuation rate is less than or equal to a first preset threshold value, it means that the degree of signal attenuation is not large, and the signal coverage strength of the corresponding position of the target coverage area can be adjusted by increasing the transmission power. The power correction value is a positive value, that is, the power correction value corresponding to the attenuation information is used to increase the transmission power; in another possible implementation, if the signal attenuation rate is greater than the first preset threshold value, it means that the obstacle has too much influence on the signal, and normal signal coverage cannot be achieved by only increasing the transmission power. The power correction value is a negative value, that is, by reducing or turning off the vibrator unit to save energy, the corresponding position in the target coverage area is covered by signals from other angles through other antennas adjacent to the Luneburg lens antenna to improve the efficiency of signal coverage.

[0081] Step S203: obtaining a preset signal strength.

[0082] Exemplarily, the preset signal strength is the signal strength that needs to be achieved in the target coverage area, such as 21 dBi. The signal strength is preset according to specific needs, and the signal strength may be different in different application scenarios, which will not be described here.

[0083] Step S204: determining the transmission power of the vibrator units corresponding to different positions in the target coverage area according to the preset signal strength, distance information and power correction value.

[0084] Exemplarily, the transmission power of each vibrator unit is determined according to the signal strength that needs to be achieved in the target coverage area, as well as the distance information and the power correction value, so that when the narrow beam emitted by each vibrator unit is transmitted to the corresponding position of the target coverage area, the signal coverage strength at each position can be uniform. Specifically, exemplarily, the transmission power of the vibrator unit is directly proportional to the distance from the Luneburg lens antenna to different positions of the target coverage area. According to the known signal attenuation rules, the corresponding attenuation values ​​at different distances are determined, and the sum of the attenuation value, the power correction value and the signal strength is the transmission power.

[0085] Of course, it can be understood that steps S202A and S202B in this embodiment are optional steps. When steps S202A and S202B are not performed, the influence of the power correction value on the transmission power does not need to be considered in step S204, that is, the transmission power of the vibrator unit corresponding to different positions in the target coverage area is determined according to the preset signal strength and distance information. Its implementation method is similar to that in step S204, and will not be repeated here.

[0086] Figure 8 A schematic diagram of another Luneburg lens antenna provided in an embodiment of the present disclosure is shown in FIG. Figure 8 As shown, in a possible implementation, the Luneburg lens antenna includes two vertically arranged Luneburg lenses, namely a first Luneburg lens and a second Luneburg lens, and the two Luneburg lenses are provided with a plurality of vibrator units corresponding to each other in the vertical direction. In step S204, after determining the transmission power of the vibrator units corresponding to different positions of the target coverage area according to the preset signal strength, distance information and power correction value, the transmission power is used as the total transmission power, and the transmission power of the two vibrator units of the two Luneburg lenses at the corresponding positions is determined according to the preset weight coefficient.

[0087] In another possible implementation, the Luneburg lens antenna includes two horizontally arranged Luneburg lenses, and the two Luneburg lenses are provided with a plurality of vibrator units along the same horizontal direction. Exemplarily, the plurality of vibrator units of the two Luneburg lenses are respectively arranged in a fan shape on the same horizontal plane along the contours of the Luneburg lenses. The transmission power of the vibrator units corresponding to different positions of the target coverage area is determined according to the preset signal strength and the distance information, including: determining the total transmission power corresponding to different positions of the target coverage area according to the preset signal strength and the distance information; and determining the transmission power of the vibrator units of the two Luneburg lenses at each position according to a preset weight coefficient and the total transmission power.

[0088] In a possible implementation, the shaping parameter includes shaping angle information, and the shaping angle information is used to characterize the incident angle of the vibrator unit when the narrow beam emitted by the vibrator unit through the Luneburg lens reaches different positions in the target coverage area. After step S204, it also includes:

[0089] Step S205, determining different positions of the target coverage area and the azimuth angles of the Luneburg lens antenna according to the coverage area information.

[0090] Step S206, determining the shaping angle information of the vibrator unit according to the azimuth angle.

[0091] For example, refer to Figure 6 The shaping angle information includes a horizontal shaping angle and / or a vertical shaping angle, wherein the horizontal shaping angle is θ in the figure, and the vertical shaping angles are β1 and β2 in the figure.

[0092] According to the relative position relationship between the Luneburg lens antenna represented by the coverage area information and different positions of the target coverage area, the corresponding direction angle can be determined. The direction angle corresponds to the incident angle when the vibrator unit transmits a narrow beam through the Luneburg lens. Among them, the horizontal direction angle corresponds to the horizontal incident angle, which is the horizontal shaping angle. The horizontal shaping angle is the angle between the Luneburg lens antenna and different positions of the target coverage area in the horizontal direction. By shaping the antenna through the horizontal shaping angle, each vibrator unit can emit a narrow beam to the corresponding horizontal angle. Each narrow beam corresponds to a position in the target coverage area, so that each position in the target coverage area can be covered by the signal. The vertical direction angle corresponds to the vertical incident angle, which is the vertical shaping angle. The vertical shaping angle is the angle between the Luneburg lens antenna and different positions of the target coverage area in the vertical direction.

[0093] In a possible implementation, determining the vertical shaping angle includes:

[0094] Obtain preset target height information, which is used to characterize the signal coverage height required at different locations in the target coverage area, and determine the vertical shaping angle based on the target height information and the azimuth.

[0095] Specifically, in Figure 8In the Luneburg lens antenna shown, the vertical shaping angles of the first Luneburg lens and the second Luneburg lens are determined according to the target height information. Exemplarily, the target coverage area can be a three-dimensional spatial area, wherein the target height information is used to characterize the height that needs to be covered by the signal at different positions in different target coverage areas. For different positions in different target coverage areas, the signal coverage height is different. The closer to the Luneburg lens antenna, the greater the coverage height; the farther from the Luneburg lens antenna, the smaller the coverage height. The vertical shaping angles of the vibrator unit on the first Luneburg lens and the corresponding vibrator unit on the second Luneburg lens are determined by the target height information, and the narrow beam toward the edge of the target coverage area is aliased and compressed, so that the signal energy is concentrated in a smaller longitudinal range, the signal gain is improved, and the signal coverage effect at the edge of the target coverage range is improved.

[0096] Step S207: adjusting the transmission phases of the multiple oscillator units to be the same phase.

[0097] Exemplarily, the transmission phase of the vibrator unit is controlled so that the phases of the signals transmitted by the multiple vibrators are consistent, wherein the phase consistency includes that the phases of the electromagnetic wave signals transmitted by the multiple vibrator units are the same, or differ by an integer period multiple. By adjusting the transmission phase of the vibrator unit, it is possible to avoid mutual interference between electromagnetic wave signals with different phases, thereby affecting the quality of the wireless signal.

[0098] Step S208, beamforming is performed on the Luneburg lens antenna according to the shaping parameters so that the wide beam has uniform signal strength at different locations in the target coverage area.

[0099] In this embodiment, the implementation method of step S208 is the same as that of the present application. Figure 3 The implementation method of step S103 in the illustrated embodiment is the same and will not be described in detail here.
