Description

Antennas, feeder systems and base stations

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on July 19, 2023, with application number 202310891435.9 and application name “Antenna, Antenna Feed System and Base Station”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to an antenna, an antenna feed system, and a base station. Background Art

[0003] In recent years, multi-antenna technology has become a primary means of improving communication capabilities in wireless communication systems. However, with the rapid growth in communication demand, the number of antenna elements in multi-antenna systems has increased, leading to a corresponding increase in antenna size. Antenna size affects the wind resistance of the antenna in extreme weather conditions. Generally speaking, greater wind resistance increases the pressure on the antenna and the corresponding installed equipment. Therefore, to maintain a "safe wind resistance," antenna size is limited.

[0004] Based on this, the need for the antenna size to adapt to the gradually increasing shaping capability is contradictory to the need for the antenna size to adapt to the "safe wind resistance", resulting in the inability to meet the current demand for antennas.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide an antenna, an antenna feed system, and a base station, which are used to provide an antenna that can take into account both shaping capability and wind resistance.

[0007] To achieve the above objectives, this application adopts the following technical solutions:

[0008] According to a first aspect of an embodiment of the present application, an antenna is provided, comprising a first antenna array and a second antenna array. The antenna's extremely narrow beamforming is defined as the beamforming width corresponding to when the antenna is at its maximum antenna area. The antenna's maximum antenna area is the sum of the areas of the first antenna array and the second antenna array. The first antenna array and the second antenna array are capable of relative rotation, and the angle between the first antenna array and the second antenna array can be changed by rotating at least one of the first antenna array and the second antenna array.

[0009] The antenna provided in an embodiment of the present application includes a first antenna array and a second antenna array, and the first antenna array and the second antenna array can rotate relative to each other. When the plane where the first antenna array is located and the plane where the second antenna array is located form an angle that is not equal to 180 degrees, the plane where the first antenna array is located is used as the reference plane, and the roof area of ​​the second antenna array is the projection of the second antenna array on the reference plane. Then, the roof area of ​​the second antenna array is smaller than the area of ​​the second antenna array. Therefore, compared with the first antenna array and the second antenna array being located in the same plane (the angle is 180 degrees), when the first antenna array and the second antenna array are rotated to be located in different planes (the angle is not equal to 180 degrees), the roof area of ​​the antenna will be reduced. This reduces the shaping ability of the antenna, that is, the beam will gradually become wider, but the wind resistance will become smaller. Therefore, the rotation of the first antenna array and the second antenna array will affect the beamforming ability and wind resistance index of the antenna. Based on this, the antenna provided in the embodiment of the present application can adaptively adjust the angle between the first antenna array and the second antenna array according to the beamforming requirements and the wind resistance index requirements. Without affecting the antenna beamforming capability, the antenna roof area can be reduced to ensure that the antenna meets the wind resistance index.

[0010] In one possible implementation, the first antenna array and the second antenna array can rotate relative to each other based on a first parameter. By enabling the first antenna array and the second antenna array to rotate relative to each other based on the first parameter, the relative rotation of the first antenna array and the second antenna array can be made more intelligent and accurate, thereby better balancing the performance of the antenna communication system and wind resistance safety in different wind scenarios.

[0011] In one possible implementation, the first parameter includes a wind parameter, wherein the wind parameter includes at least one of wind speed, wind direction, wind force, wind pressure, and wind load. The first antenna array and the second antenna array rotate according to the wind parameter to ensure antenna safety.

[0012] In one possible implementation, the first parameter includes a service parameter, wherein the service parameter includes at least one of service volume and service distribution direction angle. The first antenna array and the second antenna array rotate according to the service parameter to ensure communication performance of the antenna.

[0013] In one possible implementation, the first parameter includes a rotation parameter generated based on wind parameters and / or service parameters. Wind parameters include at least one of wind speed, wind direction, wind force, wind pressure, and wind load, while service parameters include at least one of traffic volume and traffic distribution angle. The antenna only receives the rotation parameter and adjusts the angle between the first and second antenna arrays based on the rotation parameter, eliminating the need to process service and wind parameters, thereby simplifying the antenna structure.

[0014] In a possible implementation, the wind parameters come from a wind parameter measuring device or a distributed unit corresponding to the antenna. Whether the wind parameters come from the distributed unit or the wind parameter measuring device, both are relatively easy to implement.

[0015] In one possible implementation, the service parameters come from the distributed unit corresponding to the antenna. The distributed unit serves as the overall control system of the base station, and the distributed unit provides the service parameters, which is easy to implement.

[0016] In one possible implementation, the rotation parameters come from the distributed unit corresponding to the antenna. The distributed unit serves as the overall control system of the base station, and providing the rotation parameters by the distributed unit is easy to implement.

[0017] In one possible implementation, at the same time, the first antenna array and the second antenna array rotate according to the first parameter. In different application scenarios, the main focus is different, and wind parameters, service parameters, or rotation parameters can be selected according to the application scenario, with a wide range of applicability.

[0018] In one possible implementation, the antenna further includes a connecting member; the first antenna array and the second antenna array are connected by the connecting member, and the connecting member is configured to drive the first and second antenna arrays to rotate relative to each other. The connecting member serves as a rotating member, and the first and second antenna arrays serve as fixed members. The connecting member drives the first and second antenna arrays to rotate relative to each other, resulting in a simple structure, easy implementation, and high antenna stability.

[0019] In one possible implementation, the connecting member includes a first connecting member and a second connecting member, the first connecting member being connected to the first antenna array, and the second connecting member being connected to the second antenna array. The connecting member includes multiple connecting members connected together, and the multiple connecting members can rotate independently, thereby facilitating independent rotation of the first antenna array and the second antenna array.

[0020] In a possible implementation, one end of the connecting member is connected to the first antenna array, and the other end of the connecting member is connected to the second antenna array. This connecting member has a simple structure and high stability.

[0021] In one possible implementation, the antenna further includes a third antenna array; the third antenna array is disposed on a side of the first antenna array away from the second antenna array; and the third antenna array and the first antenna array are capable of relative rotation. In this application, the antenna may be configured with multiple antenna arrays based on the application scenario to reconfigure the antenna's antenna area.

[0022] In one possible implementation, the third antenna array can rotate relative to the first antenna array. In this way, the first antenna array is a fixed radiating surface, and the second and third antenna arrays are adjustable radiating surfaces, thereby ensuring basic antenna performance.

[0023] In one possible implementation, the antenna further includes a fourth antenna array; the plane of the fourth antenna array intersects the plane of the second antenna array, and the fourth antenna array and the first antenna array are capable of relative rotation. In this application, the antenna can be configured with multiple antenna arrays based on the application scenario to reconfigure the antenna's antenna area, and the multiple antenna arrays can be located on multiple sides of the first antenna array.

[0024] In a possible implementation, both the first antenna array and the second antenna array are rotatable, thereby increasing the antenna's flexibility and allowing for a wide adjustment range of the angle between the first antenna array and the second antenna array.

[0025] In one possible implementation, the first antenna array and the second antenna array can be rotated to lie in the same plane. This allows the multiple first antenna elements in the first antenna array and the multiple second antenna elements in the second antenna array to form a large array with consistent arrangement characteristics, making the antenna equivalent to a large antenna with superior performance in a communication system.

[0026] In one possible implementation, the beamwidth generated when the first antenna array and the second antenna array are in the same plane is narrower than the beamwidth generated when the plane containing the first antenna array and the plane containing the second antenna array intersect. Because a narrower beam provides greater signal gain, higher energy, and better radiation, when the first and second antenna arrays are in the same plane (when the antenna surface area is at its maximum), that is, in mainstream usage, radiation at maximum gain optimizes the performance of the antenna communication system.

[0027] In one possible implementation, the second antenna array can be configured to not radiate signals, so that the antenna's extremely narrow beamforming is adjustable.

[0028] According to a second aspect of an embodiment of the present application, an antenna feed system is provided, comprising a cable and an antenna, wherein the cable is connected to the antenna; the antenna comprises any one of the antennas of the first aspect.

[0029] A third aspect of the present application provides a base station comprising a distributed unit and the antenna feed system of the second aspect, wherein the distributed unit is connected to the antenna feed system. Alternatively, the distributed unit and the antenna of any one of the first aspects are connected to the antenna.

[0030] In one possible implementation, the distributed unit is used to provide service parameters to the antenna. This approach is easy to implement.

[0031] In a possible implementation, the distributed unit is also used to provide wind parameters to the antenna. This approach is easy to implement.

[0032] In one possible implementation, the distributed unit is further configured to generate wind parameters based on meteorological information. This eliminates the need for the base station to have its own wind parameter measurement device, simplifying the structure.

[0033] In a possible implementation, the distributed unit is further configured to provide rotation parameters to the antenna. This approach is easy to implement.

[0034] In one possible implementation, the base station also includes a wind parameter measurement device. The base station's built-in wind parameter measurement device is highly similar to the environment in which the antenna is located. Therefore, using the base station's built-in wind parameter measurement device to obtain wind parameters can result in higher wind parameter accuracy.

[0035] In one possible implementation, when the base station simultaneously obtains service parameters and wind parameters, the distributed unit is configured to select the wind parameter as the first parameter for reference in rotating the first and second antenna arrays. Since wind parameters affect the safe lifespan and service parameters affect communication performance, rotating based on the wind parameter prioritizes antenna safety.

[0036] In one possible implementation, when the base station simultaneously obtains service parameters and wind parameters, the distributed unit is configured to generate rotation parameters based on the wind parameters as a reference for rotating the first and second antenna arrays. Since wind parameters affect the safe lifespan and service parameters affect communication performance, rotating based on wind parameters prioritizes antenna safety.

[0054] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0055] Hereinafter, the terms "second," "first," etc., are used for descriptive convenience only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature qualified as "second," "first," etc., may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0056] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left", and "right" may be defined including but not limited to the orientation relative to the schematic placement of the components in the drawings. It should be understood that these directional terms may be relative concepts, which are used for relative descriptions and clarifications, and may change accordingly according to changes in the orientation of the components in the drawings.

[0057] In the embodiments of this application, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, "connection" can mean fixed connection, detachable connection, or integration; it can mean direct connection or indirect connection through an intermediate medium. In addition, the term "coupling" can mean direct electrical connection or indirect electrical connection through an intermediate medium. The term "contact" can mean direct contact or indirect contact through an intermediate medium.

[0058] In the embodiments of the present application, "and / or" describes the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, and B exists alone. A and B can be singular or plural. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0059] Embodiments of the present application provide a radio access network (RAN), and further provide an antenna suitable for use with the RAN device, for improving the beamforming capability of the RAN. Furthermore, the antenna can also meet the security requirements of the RAN under different weather conditions.

[0060] Among them, the RAN can be a cellular system related to the 3rd Generation Partnership Project (3GPP), for example, a fourth generation (4G) mobile communication system, a fifth generation (5G) mobile communication system, or a future-oriented evolution system (for example, a sixth generation (6G) mobile communication system). RAN can also be an open access network (open RAN, O-RAN or ORAN) or a cloud radio access network (CRAN). RAN can also be a communication system that integrates two or more of the above systems. RAN can also be called access network equipment, RAN entity or access node, etc.

[0061] In one possible scenario, the access network device may be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next generation NodeB (gNB), a next generation base station in a sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. The access network device may be a macro base station, a micro base station or an indoor station, a relay node or a donor node, or a wireless controller in a CRAN scenario. Optionally, the access network device may also be a server, a wearable device, a vehicle or an onboard device. For example, the access network device in vehicle to everything (V2X) technology may be a road side unit (RSU).

[0062] In another possible scenario, multiple access network devices collaborate to assist the terminal in achieving wireless access, and different access network devices respectively implement part of the functions of the base station. For example, the access network device can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be set separately, or they can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). The following description is based on the base station.

[0063] Figures 1, 2A, and 2B are architectural diagrams of a base station provided in an embodiment of the present application.

[0064] As shown in FIG1 , the base station 100 provided in the embodiment of the present application includes a CU, a DU, and an antenna feed system.

[0065] The DU primarily handles Radio Link Control (RLC), Medium Access Control (MAC), and some Port Physical Layer (PHY) functions. The DU is connected to the CU, whose operations are controlled by the CU. The CU can centrally manage multiple DUs through the mid-transmission interface.

[0066] The CU is also the central unit responsible for processing higher-level protocols such as Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP).

[0067] The antenna feed system is connected to the DU. The antenna feed system is mainly used to transmit and radiate the RF signal from the transmitter module to establish a downlink from the base station to the terminal device, and to receive and transmit the uplink signal from the terminal device to establish an uplink from the terminal device to the base station.

[0068] In one possible implementation, as shown in Figure 1, the antenna feed system includes a cable and a RU, where the DU is connected to the RU via the cable. The RU is responsible for the underlying physical layer processing components, including the analog components of the radio transmitter and receiver.

[0069] In a possible implementation, as shown in FIG2A , the RU may be located in an active antenna unit (AAU), and the AAU may integrate the RU and the antenna, which are connected via a feeder line.

[0070] In another possible implementation, as shown in Figure 2B, the RU may be located in the RRU or RRH. In this case, the antenna feed system further includes an antenna externally connected to the RU, and the RU is connected to the antenna via a feeder line.

[0071] The antenna is a device within base station 100 that receives and radiates wireless signals. It converts received wireless signals into electrical signals and transmits them within the base station. It also converts the base station's radio frequency signals into wireless signals for radiating to terminal devices.

[0072] Another important function of antennas is to shape wireless signals and improve signal coverage. The antenna's shaping capability is related to the size of the antenna. Therefore, antennas with strong shaping capabilities will inevitably have larger antennas.

[0073] However, antennas are typically installed outdoors at high altitudes, where wind can directly impact their safety. The lower the wind resistance of an antenna, the safer it is. The following illustrates the relationship between antenna size and wind resistance.

[0074] Generally speaking, wind load WL is related to wind speed v squared, roof area A, and drag coefficient f. w Directly proportional.

[0075] WL=f w ·v 2 ·A

[0076] Clearly, wind resistance WL is proportional to the antenna area A. Generally speaking, the greater the wind resistance WL, the greater the pressure on the antenna. Therefore, to improve base station safety in windy weather, the antenna area must be limited. Consequently, the antenna's ultra-narrow beamforming capabilities are also limited.

[0077] 3-5 are schematic structural diagrams of an antenna provided in an embodiment of the present application.

[0078] As shown in FIG3 , antenna 20 includes a first antenna array 21 and a second antenna array 22. First antenna array 21 includes one or more first arrays 211, which are arranged, for example, with equal row and column spacing. Second antenna array 22 includes one or more second arrays 221, which are arranged, for example, with equal row and column spacing.

[0079] As shown in FIG3 , the number of first arrays 211 included in the first antenna array 21 may be the same as the number of second arrays 221 included in the second antenna array 22. As shown in FIG4 , the number of first arrays 211 included in the first antenna array 21 may be different from the number of second arrays 221 included in the second antenna array 22.

[0080] In a possible implementation, the arrangement characteristics of the plurality of first arrays 211 are the same as the arrangement characteristics of the plurality of second arrays 221 .

[0081] For example, the first antenna array 21 and the second antenna array 22 are arranged side by side along a first direction X, where the first direction X is the row direction. The second direction Y is the column direction. The column spacing between adjacent first antenna arrays 211 in the first direction X is equal to the column spacing between adjacent second antenna arrays 221 in the first direction X. The row spacing between adjacent first antenna arrays 211 in the second direction Y is equal to the row spacing between adjacent second antenna arrays 221 in the second direction Y.

[0082] In a possible implementation, the number of rows of the first elements 211 in the first antenna array 21 is the same as the number of rows of the second elements 221 in the second antenna array 22 .

[0083] For example, the first antenna array 21 and the second antenna array 22 have the same size along the second direction Y.

[0084] In a possible implementation, the number of columns of the first array 211 in the first antenna array 21 is greater than or equal to the number of columns of the second array 221 in the second antenna array 22 .

[0085] This arrangement of the first antenna array 21 and the second antenna array 22 facilitates signal transmission between the feeder and the antenna 20 .

[0086] In a possible implementation, the first antenna array 21 is configured to be coupled to a feeder, and a connection is established between the second antenna array 22 and the feeder via the first antenna array 21 .

[0087] That is to say, only the first antenna array 21 in the antenna 20 is directly connected to the feeder, and the second antenna array 22 is not directly connected to the feeder. Of course, when the first antenna array 21 and the second antenna array 22 are arranged side by side in the row direction (first direction X), the first antenna array 21 can be located on the left side of the second antenna array 22 as shown in Figure 3, and the first antenna array 21 can also be located on the right side of the second antenna array 22. Similarly, when the first antenna array 21 and the second antenna array 22 are arranged side by side in the column direction (second direction Y), the first antenna array 21 can be located on the upper side of the second antenna array 22, and the first antenna array 21 can also be located on the lower side of the second antenna array 22. The embodiment of the present application is not limited to this, and it is emphasized that of the two antenna arrays included in the antenna 20, only one antenna array is used to be directly connected to the feeder, but the first antenna array 21 and the second antenna array 22 both transmit signals through the feeder.

[0088] In the embodiment of the present application, the first antenna array 21 serves as the first radiator of the antenna 20, and the second antenna array 22 serves as the second radiator of the antenna 20. The maximum capacity of the antenna 20 is determined by the sum of the number of first antenna arrays 211 and the number of second antenna arrays 221. The maximum antenna surface area A of the antenna 20 is the sum of the area of ​​the first antenna array 21 and the area of ​​the second antenna array 22. Of course, the capacity of the antenna 20 provided in the embodiment of the present application is adjustable. At least some of the multiple first antenna arrays 211 may not radiate signals. If all of the multiple first antenna arrays 211 do not radiate signals, the first antenna array 21 does not radiate signals. At least some of the multiple second antenna arrays 221 may not radiate signals. If all of the multiple second antenna arrays 221 do not radiate signals, the second antenna array 22 does not radiate signals. If the first antenna array 21 and / or the second antenna array 22 do not radiate signals, the extremely narrow beamforming of the antenna 20 is also adjustable.

[0089] In a possible implementation, the first antenna array 21 and the second antenna array 22 are capable of rotating relative to each other.

[0090] Of course, the first antenna array 21 can be stationary while the second antenna array 22 can rotate. Alternatively, the second antenna array 22 can be stationary while the first antenna array 21 can rotate. Alternatively, both the first antenna array 21 and the second antenna array 22 can rotate. The configuration of the first antenna array 21 and the second antenna array 22 is flexible and applicable to various application scenarios.

[0091] It should be understood that the first antenna array 21 and the second antenna array 22 have the ability to rotate relative to each other, but it is not limited to the fact that the first antenna array 21 and the second antenna array 22 must rotate relative to each other.

[0092] For example, when the wind speed is greater than a set value, the first antenna array 21 and the second antenna array 22 can rotate relative to each other. When the wind speed is less than the set value, the first antenna array 21 and the second antenna array 22 remain stationary relative to each other. Of course, there is no limit to the set value; the set value can be selected based on factors such as wind resistance WL, the shapes of the first antenna array 21 and the second antenna array 22, and the connection method of the first antenna array 21 and the second antenna array 22.

[0093] In a possible implementation, as shown in FIG3 , the first antenna array 21 and the second antenna array 22 can be rotated to be in the same plane (the angle θ is equal to 180°).

[0094] At this time, the antenna area A of the antenna 20 is the sum of the area of ​​the first antenna array 21 and the area of ​​the second antenna array 22 .

[0095] In this case, for example, the spacing between a row of first antenna arrays 211 adjacent to the second antenna array 22 and a row of second antenna arrays 221 adjacent thereto is equal to the spacing between two adjacent rows of first antenna arrays 211. Alternatively, multiple first antenna arrays 211 and multiple second antenna arrays 221 can form a large array with consistent arrangement characteristics.

[0096] In another possible implementation, as shown in FIG4 , the first antenna array 21 and the second antenna array 22 can be rotated to an included angle θ that is less than 180°.

[0097] In yet another possible implementation, as shown in FIG5 , the first antenna array 21 and the second antenna array 22 can be rotated to an included angle θ greater than 180°.

[0098] At this time, the roof area A of the antenna 20 is the sum of the area of ​​the first antenna array 21 and the area of ​​the projection of the second antenna array 22 on the plane where the first antenna array 21 is located.

[0099] In one possible implementation, the beam width generated when the first antenna array 21 and the second antenna array 22 are in the same plane is narrower than the beam width generated when the plane where the first antenna array 21 is located and the plane where the second antenna array 22 is located intersect (θ≠180°).

[0100] Since narrower beams result in greater signal gain, higher energy, and better radiation, when the first antenna array 21 and the second antenna array 22 are in the same plane (when the antenna area A is at its maximum), i.e., in mainstream use, radiation at maximum gain optimizes the performance of the antenna 20 communication system.

[0101] The antenna provided in an embodiment of the present application includes a first antenna array 21 and a second antenna array 22, and the first antenna array 21 and the second antenna array 22 can rotate relative to each other. When the plane where the first antenna array 21 is located and the plane where the second antenna array 22 is located form an angle that is not equal to 180 degrees, the plane where the first antenna array 21 is located is used as the reference plane, and the roof area of ​​the second antenna array 22 is the projection of the second antenna array 22 on the reference plane. Then, the roof area of ​​the second antenna array 22 is smaller than the area of ​​the second antenna array 22. Therefore, compared with the first antenna array 21 and the second antenna array 22 being located in the same plane (angle θ = 180 degrees), when the first antenna array 21 and the second antenna array 22 are rotated to be located in different planes (angle θ ≠ 180 degrees), the roof area of ​​the antenna 20 will be reduced. This reduces the shaping ability of the antenna 20, that is, the beam will gradually become wider, but the wind resistance will become smaller. Therefore, the rotation of the first antenna array 21 and the second antenna array 22 will affect the beamforming ability and wind resistance index of the antenna 20. Based on this, the antenna 20 provided in the embodiment of the present application can adaptively adjust the angle between the first antenna array 21 and the second antenna array 22 according to the beamforming requirements and the wind resistance index requirements. Without affecting the beamforming capability of the antenna 20, the roof area of ​​the antenna 20 can be reduced to ensure that the antenna 20 meets the wind resistance index.

[0102] For example, The maximum area of ​​the sky A max , limited by the "safety wind resistance" WL max Maximum wind speed v max In "Safety Wind Resistance" WL max Under certain conditions, the maximum wind speed v max When it increases, the maximum area A of the sky surface needs to be reduced. max It is assumed that during engineering design, when the first antenna array 21 and the second antenna array 22 are in the same plane, the maximum wind speed v under “safe wind resistance” is max∈[40 55]m / s. When the wind force is level 12, the wind speed is 32.7-36.9m / s. Therefore, when the wind force exceeds level 12, in order to ensure "safe wind resistance", it is necessary to reduce the maximum area of ​​the roof A. max . The antenna 20 provided in the embodiment of the present application can reduce the roof area A of the antenna 20 in such extreme weather conditions by rotating at least one of the first antenna array 21 and the second antenna array 22. It should be noted that when the wind speed v is large, although the roof area A is reduced, the demand for communication in such extreme weather conditions will also be greatly reduced. Then, the demand for the beamforming capability of the antenna 20 will also be reduced. Therefore, in this case, while reducing the roof area A and ensuring safety performance, the basic working size and basic performance of the antenna 20 can still be guaranteed.

[0103] For another example, when antenna 20 requires "wide coverage," at least one of the first antenna array 21 and the second antenna array 22 can be rotated to adjust the first antenna array 21 and the second antenna array 22 to an angle with wider coverage. When antenna 20 needs to change its coverage area, at least one of the first antenna array 21 and the second antenna array 22 can also be rotated to face the desired coverage area.

[0104] Regarding the relative rotation of the first antenna array 21 and the second antenna array 22:

[0105] In one possible implementation, the first antenna array 21 and the second antenna array 22 are mechanically connected. Wind resistance and wind force form a pair of reaction forces. When the wind force exceeds a preset value, the wind force naturally pushes the first antenna array 21 and the second antenna array 22 to rotate in the direction of the wind to reduce wind resistance. When the wind resistance is less than the wind force, the first antenna array 21 and the second antenna array 22 stop rotating.

[0106] In another possible implementation, the first antenna array 21 and the second antenna array 22 can rotate relative to each other according to a first parameter.

[0107] In other words, the rotation of the first antenna array 21 and the second antenna array 22 is no longer directly determined by wind force, but is instead controlled by a first parameter. The first parameter carries information indicating how the first antenna array 21 and the second antenna array 22 should rotate. For example, the first antenna array 21 rotates by a first angle in a first direction based on the first parameter, so that the angle between the first antenna array 21 and the second antenna array 22 is the first angle. Alternatively, the second antenna array 22 rotates by a second angle in a second direction based on the first parameter, so that the angle between the first antenna array 21 and the second antenna array 22 is the second angle. Alternatively, the first antenna array 21 rotates by a third angle in a third direction based on the first parameter, and the second antenna array 22 rotates by a fourth angle in a fourth direction based on the first parameter, so that the angle between the first antenna array 21 and the second antenna array 22 is the third angle.

[0108] By causing the first antenna array 21 and the second antenna array 22 to rotate relative to each other according to the first parameter, the relative rotation of the first antenna array 21 and the second antenna array 22 can be made more intelligent and accurate, thereby better achieving a balance between the performance of the communication system of the antenna 20 and wind resistance safety in different wind scenarios.

[0109] In a possible implementation, the first parameter includes a wind parameter.

[0110] For example, the wind parameters include at least one of wind speed, wind direction, wind force, wind pressure, and wind load. Wind speed refers to the speed of air flow, wind direction refers to the direction of wind blowing, wind force refers to the force exerted by wind on an object, wind pressure refers to the pressure exerted by wind on the surface of an object, and wind load refers to the impact of wind on the structure of the object.

[0111] Then, the first antenna array 21 and the second antenna array 22 adjust the rotation angle based on the wind parameters, thereby adjusting the angle (or geometric structure) between the first antenna array 21 and the second antenna array 22 to achieve both the wind resistance safety of the antenna 20 and the performance of the communication system in different wind scenarios.

[0112] For example, under different wind parameters, the first antenna array 21 and the second antenna array 22 correspond to different angles, so that the antenna 20 responds to different wind resistances. For example, under a first wind parameter, the first antenna array 21 and the second antenna array 22 form a first angle. Under a second wind parameter, the first antenna array 21 and the second antenna array 22 form a second angle. The first and second wind parameters differ, and so do the first and second angles.

[0113] In one possible implementation, the wind parameters come from the DU corresponding to the antenna 20. For example, in the base station 100 provided in the embodiment of the present application, the DU is used to provide the wind parameters to the antenna 20. For example, the DU is used to generate the wind parameters based on meteorological information.

[0114] In another possible implementation, the wind parameters come from a wind parameter measuring device. Of course, the wind parameter measuring device may be integrated into the antenna 20 or may not be integrated into the antenna 20. For example, the base station 100 provided in an embodiment of the present application also includes a wind parameter measuring device, which is used to obtain wind parameters. Figure 6 is a structural schematic diagram of a wind parameter measuring device provided in an embodiment of the present application. Of course, Figure 6 is only a schematic diagram and does not limit it in any way. The embodiment of the present application does not limit the location of the wind parameter measuring device in the base station 100. In one possible implementation, the setting height of the wind parameter measuring device is the same as or similar to the setting height of the antenna 20. For example, the setting height of the wind parameter measuring device is higher than the setting height of the antenna 20. In this way, the wind parameter measured by the wind parameter measuring device is greater than the wind parameter actually borne by the antenna 20. Using the larger wind parameter as the basis for rotation can improve the safety of the antenna 20.

[0115] Whether the wind parameters come from DU or wind parameter measuring device, they can be set according to actual usage requirements.

[0116] In another possible implementation, the first parameter includes a service parameter.

[0117] For example, the service parameters include at least one of the service volume (or service load) and the service distribution direction angle. The service volume refers to the traffic of the base station, which is the total amount of data transmitted by the base station within a period of time. This data includes all data received and sent by the base station, such as voice, text messages, data, etc. The service distribution direction angle refers to the direction and angle of the base station traffic. Then, the first antenna array 21 and the second antenna array 22 adjust the rotation angle based on the service parameters, thereby adjusting the angle (or geometric structure) between the first antenna array 21 and the second antenna array 22, so as to achieve both the service requirements of the antenna 20 and the performance of the communication system under different service requirements.

[0118] For example, under different service parameters, the first antenna array 21 and the second antenna array 22 correspond to different angles, so that the antenna 20 has different coverage ranges. For example, under first service parameters, the first antenna array 21 and the second antenna array 22 form a first angle. Under second service parameters, the first antenna array 21 and the second antenna array 22 form a second angle. The first and second service parameters differ, and so do the first and second angles.

[0119] In a possible implementation, the service parameters come from the DU corresponding to the antenna 20. For example, in the base station 100 provided in the embodiment of the present application, the DU is used to provide the service parameters to the antenna 20.

[0120] In another possible implementation, the first parameter may include a rotation parameter, where the rotation parameter is generated based on a wind parameter and / or a business parameter.

[0121] It can also be understood that the first parameter received by the antenna 20 includes rotation control information, and the DU directly controls the rotation of the first antenna array 21 and the second antenna array 22 according to the rotation parameter in the first parameter. Alternatively, the rotation can also be controlled by the RU.

[0122] For example, the rotation parameter characterizes the result of the rotation.

[0123] For example, the rotation parameter may be to control the first antenna array 21 to rotate counterclockwise to be perpendicular to the second antenna array 22. Alternatively, the rotation parameter may be to control the first antenna array 21 to rotate clockwise to form an angle of 120° with the second antenna array 22.

[0124] Alternatively, for example, the rotation parameter characterizes the process of rotation.

[0125] For example, the rotation parameter may be to control the first antenna array 21 to rotate counterclockwise by 90°. Alternatively, the rotation parameter may be to control the first antenna array 21 to rotate clockwise by 60°.

[0126] Of course, the above enumeration is only for illustration and does not constitute any limitation.

[0127] In one possible implementation, the rotation parameter comes from the DU corresponding to antenna 20. The DU directly processes wind parameters and / or service parameters to generate the rotation parameter. For example, base station 100 obtains service parameters, and the DU generates the rotation parameter based on the service parameters. For example, the service parameter is the service distribution angle, which indicates that there are service demands both directly in front of and to the sides of antenna 20. The DU generates the rotation parameter based on the service parameter, and the rotation parameter controls the first antenna array 21 to rotate 90° counterclockwise.

[0128] Alternatively, for example, base station 100 obtains a wind parameter, and the DU generates a rotation parameter based on the wind parameter. For example, the wind parameter is wind speed, which is a hurricane-force wind speed. The DU generates the rotation parameter based on the wind parameter, and the rotation parameter controls the first antenna array 21 to rotate 90° counterclockwise.

[0129] Alternatively, for example, when the base station 100 obtains the service parameters and the wind parameters, the DU is used to generate the rotation parameters according to the wind parameters to ensure the safety of the antenna 20 .

[0130] For example, the service parameter is the traffic distribution angle, which indicates a high demand for traffic directly in front of antenna 20. Therefore, the first antenna array 21 and the second antenna array 22 must be located in the same plane to ensure optimal communication performance. The wind parameter is wind speed. At hurricane-force wind speeds, the first antenna array 21 and the second antenna array 22 must be perpendicular to ensure the safety of antenna 20. In this case, the DU generates a rotation parameter based on the wind parameter. The rotation parameter controls the first antenna array 21 to rotate 90° counterclockwise.

[0131] Alternatively, for example, when base station 100 obtains service parameters and wind parameters, the DU is used to generate a rotation parameter based on the service parameters to ensure the communication capability of antenna 20. For example, the service parameter is the service distribution direction angle, which indicates that there is a large service demand directly in front of antenna 20. The first antenna array 21 and the second antenna array 22 are located in the same plane to achieve better communication performance of antenna 20. The wind parameter is the wind speed. At hurricane-level wind speed, the first antenna array 21 and the second antenna array 22 are perpendicular to ensure the safety performance of antenna 20. In this case, the DU generates a rotation parameter based on the service parameter. The rotation parameter controls the rotation of the first antenna array 21 to be in the same plane as the second antenna array 22.

[0132] Or, for example, when the base station 100 obtains the service parameters and wind parameters, the DU is used to generate the rotation parameters according to the average value of the rotation angle corresponding to the service parameters and the rotation angle corresponding to the wind parameters, so as to take into account both the security and communication capability of the antenna 20.

[0133] For example, the service parameter is the service distribution angle. This indicates a high demand for services directly in front of antenna 20. First antenna array 21 and second antenna array 22 must be coplanar for optimal communication performance. The wind parameter is wind speed. At hurricane-force wind speeds, the safety of antenna 20 can only be guaranteed if first antenna array 21 and second antenna array 22 are perpendicular. In this case, the DU generates a rotation parameter based on the average of the rotation angle corresponding to the service parameter and the rotation angle corresponding to the wind parameter. The rotation parameter controls the counterclockwise rotation of first antenna array 21 to form a 240° angle with second antenna array 22.

[0134] In yet another possible implementation, the first parameter includes a wind parameter and a service parameter.

[0135] That is, the rotation angles of the first antenna array 21 and the second antenna array 22 may be determined based on wind parameters, and the rotation angles of the first antenna array 21 and the second antenna array 22 may also be determined based on service parameters.

[0136] In a possible implementation, although the first parameter includes a wind parameter and a service parameter, at the same time, the first antenna array 21 and the second antenna array 22 rotate according to only one of the wind parameter and the service parameter.

[0137] For example, although at a certain moment, the first parameter includes the wind parameter and the service parameter, the first antenna array 21 and the second antenna array 22 are rotated based on only one of the wind parameter or the service parameter to adjust the angle θ.

[0138] In the first case, at a certain moment, only the wind parameters indicate that the first antenna array 21 and the second antenna array 22 need to rotate. Then, the DU provides the wind parameters to the antenna 20.

[0139] In the second case, at a certain moment, only the service parameters indicate that the first antenna array 21 and the second antenna array 22 need to rotate. Then, the DU provides the service parameters to the antenna 20.

[0140] In the third case, at a certain moment, both the wind parameters and the service parameters indicate that the first antenna array 21 and the second antenna array 22 need to rotate. However, the first antenna array 21 and the second antenna array 22 only rotate according to the wind parameters. Then, when the base station 100 obtains the service parameters and the wind parameters at the same time, the DU is used to selectively provide the wind parameters to the antenna 20 as the first parameter for reference in the rotation of the first antenna array 21 and the second antenna array 22 in the antenna 20. Alternatively, it can be understood that when the antenna 20 needs to rotate based on both the wind parameters and the service parameters, the DU only provides the wind parameters to the antenna 20, without providing the service parameters, in order to first ensure the safety of the antenna 20. Since the wind parameters affect the safe life, and the service parameters affect the communication effect. Therefore, rotating based on the wind parameters can prioritize the safety of the antenna 20.

[0141] In the fourth case, at a certain moment, both the wind parameters and the service parameters indicate that the first antenna array 21 and the second antenna array 22 need to rotate. However, the first antenna array 21 and the second antenna array 22 only rotate according to the service parameters. Then, when the base station 100 obtains the service parameters and the wind parameters, the DU is used to select and provide the service parameters to the antenna 20 as the first parameter for reference in the rotation of the first antenna array 21 and the second antenna array 22 in the antenna 20. Alternatively, it can be understood that when the antenna 20 needs to rotate based on both the wind parameters and the service parameters, the DU only provides the service parameters to the antenna 20, and does not provide the wind parameters, so as to first ensure the communication effect of the antenna 20. In some application scenarios with relatively high requirements for communication effect, rotation based on the service parameters can give priority to ensuring the communication effect.

[0142] In the fifth scenario, at a certain moment, the first parameters include wind parameters and service parameters. The first antenna array 21 and the second antenna array 22 need to rotate based on the wind parameters and service parameters to adjust the angle θ. For example, the first antenna array 21 and the second antenna array 22 rotate based on the service parameters first, and then based on the wind parameters. In this case, the DU first provides the service parameters to the antenna 20, and then the wind parameters. Alternatively, for example, the first antenna array 21 and the second antenna array 22 rotate based on the wind parameters first, and then based on the service parameters. In this case, the DU first provides the wind parameters to the antenna 20, and then the service parameters.

[0143] However, regardless of whether the first antenna array 21 and the second antenna array 22 rotate based solely on wind parameters, based solely on service parameters, or based on both wind parameters and service parameters, the first antenna array 21 and the second antenna array 22 rotate based solely on one of the wind parameters and service parameters at the same time. If the first antenna array 21 and the second antenna array 22 rotate based on both wind parameters and service parameters, the first antenna array 21 and the second antenna array 22 may rotate twice before determining the angle θ.

[0144] In another possible implementation, the first parameter includes a wind parameter and a service parameter. At the same time, the first antenna array 21 and the second antenna array 22 rotate according to the wind parameter and the service parameter.

[0145] For example, the DU provides the antenna 20 with an average value of a rotation angle corresponding to a service parameter and a rotation angle corresponding to a wind parameter, so as to take into account both the security and communication capability of the antenna 20 .

[0146] Or, for example, at the previous moment, the application scenario is: the wind speed is low, and the traffic volume is the largest in the direction directly in front. Therefore, the first antenna array 21 and the second antenna array 22 are located in the same plane, perpendicular to the direction directly in front. At the current moment, the application scenario changes: the wind force parameter indicates that the wind speed has increased, and the angle between the first antenna array 21 and the second antenna array 22 needs to be changed. The traffic parameter indicates that the traffic volume in the direction deflected 45° counterclockwise from the direction directly in front has become the largest, and the orientation of the first antenna array 21 needs to be rotated. At this time, the DU instructs the first antenna array 21 to deflect 45° counterclockwise and the second antenna array 22 to rotate 90° clockwise to take into account both the wind force parameter and the traffic parameter.

[0147] In yet another possible implementation, the first parameter includes a wind parameter and a rotation parameter.

[0148] In yet another possible implementation, the first parameter includes a business parameter and a rotation parameter.

[0149] In yet another possible implementation, the first parameter includes a wind parameter, a business parameter, and a rotation parameter.

[0150] For example, when the antenna 20 receives only one parameter, the first antenna array 21 and the second antenna array 22 rotate based on the one parameter. When the antenna 20 receives multiple parameters, the priorities of the multiple parameters are: rotation parameter, wind parameter, and service parameter.

[0151] Continuing to refer to FIG. 3 , in a possible implementation, the first antenna array 21 and the second antenna array 22 are connected.

[0152] For example, the antenna 20 further includes a connecting member 23 , through which the first antenna array 21 and the second antenna array 22 are connected. The connecting member 23 is used to drive the first antenna array 21 and the second antenna array 22 to rotate relative to each other.

[0153] For example, the connecting member 23 drives the first antenna array 21 and the second antenna array 22 to rotate relative to each other based on the first parameter. Of course, the connecting member 23 can be directly controlled by the first parameter to drive the first antenna array 21 and the second antenna array 22 to rotate relative to each other. The connecting member 23 can also convert the first parameter to generate a control signal to drive the first antenna array 21 and the second antenna array 22 to rotate relative to each other.

[0154] In a possible implementation, the connecting member 23 is directly connected to the wind parameter measuring device shown in FIG. 6 , and the wind parameter measuring device directly drives the connecting member 23 to rotate.

[0155] The embodiment of the present application does not limit the structure of the connecting member 23 , and any structure that can drive the first antenna array 21 and the second antenna array 22 to rotate relative to each other is applicable to the embodiment of the present application.

[0156] The connecting member 23 serves as a rotating member, and the first antenna array 21 and the second antenna array 22 serve as fixed members. The connecting member 23 drives the first antenna array 21 and the second antenna array 22 to rotate relative to each other. The structure is simple, easy to implement, and the antenna 20 has high stability.

[0157] In one possible implementation, the connecting member 23 is a single component, one end of the connecting member 23 is connected to the first antenna array 21, and the other end of the connecting member 23 is connected to the second antenna array 22. This connecting member 23 has a simple structure and high stability.

[0158] In another possible implementation, the connecting member 23 includes a first connecting member and a second connecting member, the first connecting member is connected to the first antenna array 21, and the second connecting member is connected to the second antenna array 22. The first connecting member and the second connecting member are connected to realize the connection between the first antenna array 21 and the second antenna array 22.

[0159] For example, the first connecting member and the second connecting member may both be gears.

[0160] The connecting member 23 includes a plurality of connecting parts, and the plurality of connecting parts can rotate independently, which helps to achieve independent rotation of the first antenna array 21 and the second antenna array 22.

[0161] FIG7 is a schematic structural diagram of an antenna provided in an embodiment of the present application.

[0162] In a possible implementation, as shown in FIG7 , the antenna 20 further includes a third antenna array 24 , which includes one or more third arrays 241 , where the multiple third arrays 241 are arranged, for example, in equal row and column spacing.

[0163] The third antenna array 24 is arranged on a side of the first antenna array 21 away from the second antenna array 22 . Alternatively, it can be understood that the second antenna array 22 and the third antenna array 24 are arranged on opposite sides of the first antenna array 21 .

[0164] Of course, the structure of the third antenna array 24 may be identical to, or may not be identical to, the structure of the second antenna array 22, or may be completely different. For example, the number of third antenna elements 241 included in the third antenna array 24 may be the same as or different from the number of second antenna elements 221 included in the second antenna array 22. Alternatively, the dimensions of the third antenna array 24 and the dimensions of the second antenna array 22 may be the same as or different from each other.

[0165] In a first possible implementation manner, the first antenna array 21 is connected to a pole in the base station 100 .

[0166] In a possible implementation, the first antenna array 21 is fixedly connected to a pole in the base station 100 , for example, and the first antenna array 21 is stationary.

[0167] In another possible implementation, the first antenna array 21 is rotatably connected to a pole in the base station 100 via a rotating device or other structure, and the first antenna array 21 can also rotate relative to the second antenna array 22 and / or the third antenna array 24.

[0168] At the same time, optionally, the second antenna array 22 can be rotated relative to the first antenna array 21 .

[0169] Alternatively, optionally, the third antenna array 24 may be rotated relative to the first antenna array 21 .

[0170] In a second possible implementation, the second antenna array 22 is connected to a pole in the base station 100 .

[0171] In a possible implementation, the second antenna array 22 is fixedly connected to a pole in the base station 100 , for example, and the second antenna array 22 is stationary.

[0172] In another possible implementation, the second antenna array 22 is rotatably connected to a pole in the base station 100 via a structure such as a rotating device, and the second antenna array 22 can also rotate relative to the first antenna array 21 .

[0173] At the same time, optionally, the first antenna array 21 can be rotated relative to the second antenna array 22 .

[0174] Alternatively, optionally, the third antenna array 24 may be rotated relative to the first antenna array 21 .

[0175] In a third possible implementation, the third antenna array 24 is connected to a pole in the base station 100 .

[0176] In a possible implementation, the third antenna array 24 is fixedly connected to a pole in the base station 100, for example, and the third antenna array 24 is stationary.

[0177] In another possible implementation, the third antenna array 24 is rotatably connected to a pole in the base station 100 via a structure such as a rotating device, and the third antenna array 24 can also rotate relative to the first antenna array 21 .

[0178] At the same time, optionally, the first antenna array 21 can be rotated relative to the third antenna array 24.

[0179] Alternatively, optionally, the second antenna array 22 may be rotated relative to the first antenna array 21 .

[0180] In a possible implementation, the first antenna array 21 and the third antenna array 24 are connected via a connecting member 23 , and the connecting member 23 is used to drive the first antenna array 21 and the third antenna array 24 to rotate relative to each other.

[0181] For example, the first antenna array 21 , the second antenna array 22 or the third antenna array 24 may all be rotatable.

[0182] Alternatively, for example, the first antenna array 21 is stationary, the third antenna array 24 is rotatable relative to the first antenna array 21 , and the second antenna array 22 is rotatable relative to the first antenna array 21 .

[0183] In this way, the first antenna array 21 is a fixed radiation surface, and the second antenna array 22 and the third antenna array 24 are adjustable radiation surfaces, so as to ensure the basic performance of the antenna 20 .

[0184] 8-10 are schematic diagrams of beam width provided in an embodiment of the present application.

[0185] In one possible implementation, the beam width generated when the first antenna array 21, the second antenna array 22, and the third antenna array 24 are in the same plane (θ = 180°) is narrower than the beam width generated when the plane where the second antenna array 22 and the plane where the third antenna array 24 are located respectively intersect with the plane where the first antenna array 21 is located (θ ≠ 180°).

[0186] For example, in Figure 8, the first antenna array 21, the second antenna array 22, and the third antenna array 24 are in the same plane, and the beam generated by antenna 20 is the narrowest. For example, antenna 20 generates four narrow beams.

[0187] In Figure 9 , the second antenna array 22 and the third antenna array 24 are both rotated inward (in the direction of θ>180°). The planes of the second antenna array 22 and the third antenna array 24 intersect with the plane of the first antenna array 21. The beam generated by antenna 20 has a wider beam width than the beam width generated by the angle shown in Figure 8 . For example, antenna 20 generates two medium-width beams.

[0188] In Figure 10, second antenna array 22 and third antenna array 24 are further rotated inward based on the angle shown in Figure 9. The planes of second antenna array 22 and third antenna array 24 intersect with the plane of first antenna array 21. The beam generated by antenna 20 has a wider beam width than that generated by the angle shown in Figure 9. For example, antenna 20 generates a wide beam.

[0189] Of course, the principle when the second antenna array 22 and the third antenna array 24 are both rotated outward (in the direction of θ<180°) is the same as the principle when the second antenna array 22 and the third antenna array 24 are both rotated inward.

[0190] 11 and 12 are schematic structural diagrams of an antenna provided in an embodiment of the present application.

[0191] In a possible implementation, as shown in FIG11 , the antenna 20 further includes a fourth antenna array 25 , which includes one or more fourth arrays 251 , where the plurality of fourth arrays 251 are arranged, for example, in equal row and column spacing.

[0192] The plane where the fourth antenna array 25 is located intersects with the plane where the second antenna array 22 is located.

[0193] As shown in FIG11 , for example, fourth antenna array 25 and second antenna array 22 are located on one side of first antenna array 21 along the row direction, and on the other side of first antenna array 21 along the column direction. For example, along the row direction, second antenna array 22 is located on the side of first antenna array 21. Then, along the column direction, fourth antenna array 25 is located on the side of first antenna array 21.

[0194] Alternatively, as shown in FIG. 12 , the fourth antenna array 25 is located on one side of the second antenna array 22 .

[0195] The fourth antenna array 25 and the first antenna array 21 can rotate relative to each other. For example, the first antenna array 21 and the fourth antenna array 25 are connected via a connecting member 23, and the connecting member 23 is used to drive the first antenna array 21 and the fourth antenna array 25 to rotate relative to each other.

[0196] Alternatively, for example, the first antenna array 21 is stationary, and the fourth antenna array 25 is rotatable relative to the first antenna array 21 .

[0197] Of course, the antenna 20 may further include a fifth antenna array, and the fifth antenna array and the fourth antenna array 25 are arranged on two opposite sides of the first antenna array 21 .

[0198] In the embodiment of the present application, the cells corresponding to the multiple antenna arrays included in antenna 20 can be the same or different, and this embodiment of the present application is not limited to this. In addition, the multiple antenna arrays included in antenna 20 can be active or inactive to adjust the beamforming capability of antenna 20.

[0199] The present application also provides an antenna feed system, and any of the antennas 20 shown above can be used in the antenna feed system provided in the present application. The antenna feed system can be, for example, the antenna feed system shown in Figures 1 to 2B above.

[0200] The above is only a specific embodiment of the present application, but the scope of protection of this application is not limited to this. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
