Description

Technical Field

[0001] 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

[0002] In recent years, in wireless communication systems, multi-antenna technology has become a major means of improving communication capabilities. However, with the rapid growth of communication needs, the number of antenna arrays in multi-antennas has increased, resulting in an increase in the size of the antenna. The size of the antenna will affect the wind resistance of the antenna in extreme weather. Generally speaking, the greater the wind resistance, the greater the pressure on the antenna and the corresponding installation equipment. Therefore, in order to maintain "safe wind resistance", the size of the antenna is limited.

[0003] Based on this, the need for the antenna size to adapt to the increasingly high shaping capability is contradictory to the need for the antenna size to adapt to the "safe wind resistance", which results in the inability to meet current antenna demands. Summary of the invention

[0004] 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.

[0005] In order to achieve the above objectives, this application adopts the following technical solutions:

[0006] In a first aspect of an embodiment of the present application, an antenna is provided, the antenna comprising a first antenna array and a second antenna array, and the extremely narrow beamforming of the antenna is the beamforming width corresponding to when the antenna is at a maximum antenna area. The maximum antenna area of ​​the antenna is the sum of the area of ​​the first antenna array and the area of ​​the second antenna array. The first antenna array and the second antenna array can rotate relative to each other, 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.

[0007] The antenna provided in the 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°, 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 (angle is 180°), when the first antenna array and the second antenna array are rotated to be located in different planes (angle is not equal to 180°), the roof area of ​​the antenna will be reduced. The shaping ability of the antenna is reduced, 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's roof area can be reduced to ensure that the antenna meets the wind resistance index.

[0008] In a possible implementation, the first antenna array and the second antenna array can rotate relative to each other according to the first parameter. By making the first antenna array and the second antenna array rotate relative to each other according to the first parameter, the relative rotation of the first antenna array and the second antenna array can be made more intelligent and accurate, so as to better achieve the performance of the communication system of the antenna and the wind resistance safety in different wind scenarios.

[0009] In a 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 the safety of the antenna.

[0010] In a possible implementation, the first parameter includes a service parameter, wherein the service parameter includes at least one of a service volume and a service distribution direction angle. The first antenna array and the second antenna array rotate according to the service parameter to ensure the communication effect of the antenna.

[0011] In a possible implementation, the first parameter includes a rotation parameter; the rotation parameter is generated based on a wind parameter and / or a service parameter. The wind parameter includes at least one of wind speed, wind direction, wind force, wind pressure and wind load, and the service parameter includes at least one of service volume and service distribution direction angle. The antenna only receives the rotation parameter, and adjusts the angle between the first antenna array and the second antenna array according to the rotation parameter, without processing the service parameter and the wind parameter, which can simplify the structure of the antenna.

[0012] 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 a distributed unit or a wind parameter measuring device, it is relatively easy to implement.

[0013] In a 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.

[0014] In a possible implementation, the rotation parameter comes from a 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 rotation parameter, which is easy to implement.

[0015] In a 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, business parameters, or rotation parameters can be selected according to the application scenario, which has a wide range of applications.

[0016] In a 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 used to drive the first antenna array and the second antenna array to rotate relative to each other. The connecting member serves as a rotating member, and the first antenna array and the second antenna array serve as fixed members. The first antenna array and the second antenna array are driven to rotate relative to each other by the connecting member. The structure is simple, easy to implement, and the antenna has high stability.

[0017] In a possible implementation, the connecting member includes a first connecting member and a second connecting member, the first connecting member is connected to the first antenna array, and the second connecting member is connected to the second antenna array. The connecting member includes a plurality of connecting members connected, and the plurality of connecting members can rotate independently, which helps to realize the independent rotation of the first antenna array and the second antenna array.

[0018] 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.

[0019] In one possible implementation, the antenna further includes a third antenna array; the third antenna array is arranged on a side of the first antenna array away from the second antenna array; the third antenna array and the first antenna array can rotate relative to each other. In the present application, the antenna can be provided with multiple antenna arrays according to the application scenario to reconstruct the antenna's antenna area.

[0020] In a possible implementation, the third antenna array can rotate relative to the first antenna array. In this way, the first antenna array is a fixed radiation surface, and the second antenna array and the third antenna array are adjustable radiation surfaces, so as to ensure the basic performance of the antenna.

[0021] In one possible implementation, the antenna further includes a fourth antenna array; the plane where the fourth antenna array is located intersects with the plane where the second antenna array is located, and the fourth antenna array and the first antenna array can rotate relative to each other. In this application, the antenna can be provided with multiple antenna arrays according to the application scenario to reconstruct the antenna surface area, and the multiple antenna arrays can be located on multiple sides of the first antenna array.

[0022] In a possible implementation, both the first antenna array and the second antenna array are rotatable, so that the antenna has high flexibility and the adjustment range of the angle between the first antenna array and the second antenna array is wide.

[0023] In a possible implementation, the first antenna array and the second antenna array can be rotated to be in the same plane. In this way, the first arrays in the first antenna array and the second arrays in the second antenna array can form a large array with consistent arrangement characteristics, making the antenna equivalent to a large antenna with better performance in a communication system.

[0024] In a possible implementation, the beam width generated when the first antenna array and the second antenna array are in the same plane is narrower than the beam width generated when the plane where the first antenna array is located intersects the plane where the second antenna array is located. Since the narrower the beam, the greater the signal gain, the higher the energy, and the better the radiation effect. Therefore, when the first antenna array and the second antenna array are in the same plane (when the antenna surface area is the largest), that is, in the mainstream use state, radiation with maximum gain can optimize the performance of the antenna communication system.

[0025] In one possible implementation, the second antenna array can be configured not to radiate signals, so that the extremely narrow beamforming of the antenna is adjustable.

[0026] According to a second aspect of an embodiment of the present application, there is provided an antenna feed system, including a cable and an antenna, wherein the cable is connected to the antenna; the antenna includes the antenna of any one of the first aspects.

[0027] In a third aspect of the embodiments of the present application, a base station is provided, 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 aspect are connected to the antenna.

[0028] In a possible implementation, the distributed unit is used to provide service parameters to the antenna. This approach is easy to implement.

[0029] In a possible implementation, the distributed unit is also used to provide wind parameters to the antenna. This approach is easy to implement.

[0030] In a possible implementation, the distributed unit is also used to generate wind parameters according to meteorological information. In this way, the base station does not need to carry its own wind parameter measurement device, and the structure is simple.

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

[0032] In a possible implementation, the base station further includes a wind parameter measuring device. The wind parameter measuring device of the base station has a high similarity with the environment in which the antenna is located. Therefore, the wind parameter is obtained by using the wind parameter measuring device of the base station, and the wind parameter is more accurate.

[0033] In a possible implementation, when the base station obtains the service parameter and the wind parameter at the same time, the distributed unit is used to select the wind parameter as the first parameter for reference in the rotation of the first antenna array and the second antenna array in the antenna. Since the wind parameter affects the safety life and the service parameter affects the communication effect, the safety of the antenna can be prioritized by rotating based on the wind parameter.

[0034] In a possible implementation, when the base station obtains the service parameters and the wind parameters at the same time, the distributed unit is used to generate the rotation parameters for reference of the first antenna array and the second antenna array in the antenna according to the wind parameters. Since the wind parameters affect the safety life and the service parameters affect the communication effect, the safety of the antenna can be guaranteed first by rotating based on the wind parameters.

[0052] 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 of the embodiments.

[0053] In the following, the terms "second", "first", etc. are used only for convenience of description and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "second", "first", etc. may explicitly or implicitly include one or more of the feature. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0054] 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 description and clarification, and may change accordingly according to changes in the orientation of the components in the drawings.

[0055] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. In addition, the term "coupled" can be a direct electrical connection or an indirect electrical connection through an intermediate medium. The term "contact" can be a direct contact or an indirect contact through an intermediate medium.

[0056] In the embodiments of the present application, "and / or" describes the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B may be singular or plural. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0057] The embodiment of the present application provides a radio access network (RAN), and further provides an antenna suitable for the radio access network device, which is used to enhance the beamforming capability of the radio access network, and in addition, can also meet the security requirements of the radio access network under different weather conditions.

[0058] 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 (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.

[0059] 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 the vehicle to everything (V2X) technology may be a road side unit (RSU).

[0060] 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 may 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 may be separately configured, or may be included in the same network element, such as a baseband unit (BBU). The RU may be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). The following description will be based on the base station.

[0061] Figure 1 , Figure 2A , Figure 2B An architectural diagram of a base station provided in an embodiment of the present application.

[0062] like Figure 1 As shown, the base station 100 provided in the embodiment of the present application includes a CU, a DU, and an antenna feed system.

[0063] DU is mainly used to process the Radio Link Control (RLC), Medium Access Control (MAC) and some Port Physical Layer (PHY) functions. DU is connected to CU, and the operation of DU is controlled by CU. CU can centrally manage multiple DUs through the mid-transmission interface.

[0064] CU is also the central unit responsible for processing high-level protocols such as Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP).

[0065] The antenna and feed system is connected to the DU. The antenna and 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.

[0066] In one possible implementation, Figure 1 As shown in the figure, the antenna feed system includes cables and RUs, and the DU is connected to the RU through cables. The RU is responsible for the components of the underlying physical layer processing, including the analog components of the radio transmitter and receiver.

[0067] In one possible implementation, Figure 2A As shown, the RU may be located in an active antenna unit (AAU), the AAU may integrate the RU and the antenna, and the RU and the antenna are connected via a feeder line.

[0068] In another possible implementation, Figure 2B As shown, the RU may be located in the RRU or the 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.

[0069] The antenna is a device in the base station 100 that receives and radiates wireless signals. The antenna converts the received wireless signals into electrical signals and transmits the electrical signals to the inside of the base station. At the same time, the antenna is also responsible for converting the radio frequency signals of the base station into wireless signals so as to radiate the signals to the terminal devices.

[0070] Another important function of the antenna is to shape the wireless signal and increase the signal coverage area, and the antenna shaping ability is related to the size of the antenna. Therefore, the antenna with strong shaping ability will inevitably have a larger antenna size.

[0071] However, antennas are usually installed outdoors at high altitudes, which means that wind will directly affect the safety of the antenna. The smaller the wind resistance of the antenna, the higher the safety of the antenna. The following is an illustration of the relationship between antenna size and wind resistance.

[0072] Generally, wind load WL is related to wind speed v squared, roof area A, and drag coefficient f w Directly proportional.

[0073] WL=f w ·v 2 ·A

[0074] Obviously, the 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, in order to improve the safety of base stations in windy weather, the area of ​​the antenna must be limited. Then, the ultra-narrow beamforming capability of the antenna will also be limited.

[0075] Figure 3-Figure 5 A schematic diagram of the structure of an antenna provided in an embodiment of the present application.

[0076] like Figure 3 As shown, the antenna 20 includes a first antenna array 21 and a second antenna array 22. The first antenna array 21 includes one or more first arrays 211, and the multiple first arrays 211 are arranged in equal row spacing and equal column spacing. The second antenna array 22 includes one or more second arrays 221, and the multiple second arrays 221 are arranged in equal row spacing and equal column spacing.

[0077] like Figure 3 As shown, 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. Figure 4 As shown, the number of first arrays 211 included in the first antenna array 21 and the number of second arrays 221 included in the second antenna array 22 may also be different.

[0078] 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 .

[0079] 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 a row direction. The second direction Y is a column direction. The column spacing between adjacent first arrays 211 in the first direction X is equal to the column spacing between adjacent second arrays 221 in the first direction X. The row spacing between adjacent first arrays 211 in the second direction Y is equal to the row spacing between adjacent second arrays 221 in the second direction Y.

[0080] In a possible implementation manner, the number of rows of the first array 211 in the first antenna array 21 is the same as the number of rows of the second array 221 in the second antenna array 22 .

[0081] For example, the first antenna array 21 and the second antenna array 22 have the same size along the second direction Y.

[0082] In a possible implementation manner, 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 .

[0083] Such arrangement of the first antenna array 21 and the second antenna array 22 facilitates signal transmission between the feeder and the antenna 20 .

[0084] In a possible implementation, the first antenna array 21 is used to couple with a feeder, and a connection is established between the second antenna array 22 and the feeder through the first antenna array 21 .

[0085] That is, 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 (the first direction X), the first antenna array 21 can be as follows Figure 3 As shown, the first antenna array 21 is located on the left side of the second antenna array 22, 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 along 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.

[0086] 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 depends on the sum of the number of the first arrays 211 and the number of the second 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 first arrays 211 in the plurality of first arrays 211 may not radiate signals. When none of the plurality of first arrays 211 radiate signals, the first antenna array 21 does not radiate signals. At least some of the second arrays 221 in the plurality of second arrays 221 may not radiate signals. When none of the plurality of second arrays 221 radiate signals, the second antenna array 22 does not radiate signals. The first antenna array 21 and / or the second antenna array 22 may not radiate signals, and then the extremely narrow beamforming of the antenna 20 is also adjustable.

[0087] In a possible implementation, the first antenna array 21 and the second antenna array 22 are capable of rotating relative to each other.

[0088] Of course, the first antenna array 21 may be stationary, and the second antenna array 22 may be rotatable. Alternatively, the second antenna array 22 may be stationary, and the first antenna array 21 may be rotatable. Alternatively, both the first antenna array 21 and the second antenna array 22 may be rotatable. The first antenna array 21 and the second antenna array 22 are flexibly arranged and can be applied to various application scenarios.

[0089] 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 first antenna array 21 and the second antenna array 22 having to rotate relative to each other.

[0090] For example, when the wind force is greater than the set value, the first antenna array 21 and the second antenna array 22 can rotate relative to each other. When the wind force is less than the set value, the first antenna array 21 and the second antenna array 22 are relatively stationary. Of course, there is no limitation on the size of the set value, and the selection of the set value can be determined by considering factors such as wind resistance WL, the shape 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.

[0091] In one possible implementation, Figure 3 As shown, 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°).

[0092] 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 .

[0093] In this case, for example, the column spacing between a column of first arrays 211 adjacent to the second antenna array 22 and a column of second arrays 221 adjacent thereto is equal to the column spacing between two adjacent columns of first arrays 211. Alternatively, it can be understood that a plurality of first arrays 211 and a plurality of second arrays 221 can form a large array with consistent arrangement characteristics.

[0094] In another possible implementation, Figure 4 As shown, the first antenna array 21 and the second antenna array 22 can be rotated to an angle θ less than 180°.

[0095] In another possible implementation, Figure 5 As shown, the first antenna array 21 and the second antenna array 22 can be rotated to an angle θ greater than 180°.

[0096] 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 projection of the second antenna array 22 on the plane where the first antenna array 21 is located.

[0097] 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 and the plane where the second antenna array 22 are located intersect (θ≠180°).

[0098] Since the narrower the beam, the greater the signal gain, the higher the energy, and the better the radiation effect, when the first antenna array 21 and the second antenna array 22 are in the same plane (when the antenna area A is the largest), that is, in the mainstream use state, the communication system performance of the antenna 20 can be optimized by radiating with the maximum gain.

[0099] The antenna provided in the 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°, 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°), when the first antenna array 21 and the second antenna array 22 are rotated to be located in different planes (angle θ≠180°), 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.

[0100] 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 the maximum area of ​​the sky is increased, it is necessary to reduce the maximum area A of the sky 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 by rotating at least one of the first antenna array 21 and the second antenna array 22. It should be pointed out that when the wind speed v is large, although the roof area A is reduced, the demand for communication will be greatly reduced in such extreme weather. 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.

[0101] For another example, when the antenna 20 needs "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 a wider coverage. When the antenna 20 needs to change the coverage area, at least one of the first antenna array 21 and the second antenna array 22 can also be rotated, and the first antenna array 21 and the second antenna array 22 face the area to be covered.

[0102] Regarding the relative rotation of the first antenna array 21 and the second antenna array 22:

[0103] In a possible implementation, the first antenna array 21 and the second antenna array 22 are mechanically connected. Wind resistance and wind force are a pair of reaction forces. When the wind force is greater than a preset value, the wind force naturally pushes the first antenna array 21 and the second antenna array 22 to rotate along the downwind direction to reduce wind resistance, until the wind resistance is less than the wind force, and the first antenna array 21 and the second antenna array 22 stop rotating.

[0104] In another possible implementation manner, the first antenna array 21 and the second antenna array 22 can rotate relative to each other according to a first parameter.

[0105] That is to say, the rotation of the first antenna array 21 and the second antenna array 22 is no longer directly determined by the wind force, but is controlled by the first parameter. The first parameter carries information indicating how the first antenna array 21 and the second antenna array 22 rotate. For example, the first antenna array 21 rotates a first angle in a first direction according to 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 a second angle in a second direction according to 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 a third angle in a third direction according to the first parameter, and the second antenna array 22 rotates a fourth angle in a fourth direction according to the first parameter, so that the angle between the first antenna array 21 and the second antenna array 22 is the third angle.

[0106] By making the first antenna array 21 and the second antenna array 22 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, so as to better achieve the performance of the communication system of the antenna 20 and the wind resistance safety in different wind scenarios.

[0107] In a possible implementation manner, the first parameter includes a wind parameter.

[0108] For example, the wind parameters include at least one of wind speed, wind direction, wind force, wind pressure and wind load. Among them, 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 influence of wind on the structure of the object.

[0109] 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.

[0110] For example, under different wind parameters, different angles correspond to each other between the first antenna array 21 and the second antenna array 22, so that the antenna 20 corresponds to different wind resistances. For example, under the first wind parameter, a first angle is formed between the first antenna array 21 and the second antenna array 22. Under the second wind parameter, a second angle is formed between the first antenna array 21 and the second antenna array 22. The first wind parameter and the second wind parameter are different, and the first angle and the second angle are also different.

[0111] In a 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 according to meteorological information.

[0112] In another possible implementation, the wind parameters come from a wind parameter measuring device. Of course, the wind parameter measuring device may be integrated in the antenna 20 or may not be integrated in the antenna 20. For example, the base station 100 provided in the embodiment of the present application further includes a wind parameter measuring device, which is used to obtain wind parameters. Figure 6 A schematic diagram of the structure of a wind parameter measurement device provided in an embodiment of the present application. Of course, Figure 6 It is only an illustration and is not intended to be limiting. The embodiment of the present application does not limit the location of the wind parameter measurement device in the base station 100. In one possible implementation, the setting height of the wind parameter measurement device is the same as or similar to the setting height of the antenna 20. For example, the setting height of the wind parameter measurement device is higher than the setting height of the antenna 20. In this way, the wind parameter measured by the wind parameter measurement 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.

[0113] Whether the wind parameters come from DU or from a wind parameter measuring device, they can be set according to actual usage requirements.

[0114] In another possible implementation manner, the first parameter includes a service parameter.

[0115] 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 in 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 a balance between the service requirements of the antenna 20 and the performance of the communication system under different service requirements.

[0116] For example, under different service parameters, different angles correspond to each other between the first antenna array 21 and the second antenna array 22, so that the antenna 20 corresponds to different coverage ranges. For example, under the first service parameter, a first angle is formed between the first antenna array 21 and the second antenna array 22. Under the second service parameter, a second angle is formed between the first antenna array 21 and the second antenna array 22. The first service parameter and the second service parameter are different, and the first angle and the second angle are also different.

[0117] 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.

[0118] In another possible implementation manner, the first parameter may include a rotation parameter, and the rotation parameter is generated based on a wind parameter and / or a business parameter.

[0119] 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.

[0120] For example, the rotation parameter characterizes the result of the rotation.

[0121] 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. Or for example, 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.

[0122] Alternatively, for example, the rotation parameter characterizes the process of rotation.

[0123] For example, the rotation parameter may be to control the first antenna array 21 to rotate 90° counterclockwise. Or, for example, the rotation parameter may be to control the first antenna array 21 to rotate 60° clockwise.

[0124] Of course, the above list is only for illustration and does not constitute any limitation.

[0125] In a possible implementation, the rotation parameter comes from the DU corresponding to the antenna 20, and the DU directly processes the wind parameters and / or service parameters to generate the rotation parameter. For example, the base station 100 obtains the service parameters, and the DU generates the rotation parameter based on the service parameters. For example, the service parameter is the service distribution direction angle, and the service distribution direction angle indicates that there are service requirements both in front of and on the side of the antenna 20. The DU generates the rotation parameter based on the service parameter, and the rotation parameter is to control the first antenna array 21 to rotate 90° counterclockwise.

[0126] Or, for example, the 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 a wind speed, and the wind speed is a hurricane level. The DU generates a rotation parameter based on the wind parameter, and the rotation parameter is to control the first antenna array 21 to rotate 90° counterclockwise.

[0127] Or, 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.

[0128] For example, the service parameter is the service distribution direction angle, which indicates that there is a large service demand in front of the antenna 20. The first antenna array 21 and the second antenna array 22 are located in the same plane, so that the communication effect of the antenna 20 can be better. The wind parameter is the wind speed. When the wind speed is hurricane-level, the first antenna array 21 and the second antenna array 22 are perpendicular, and the safety performance of the antenna 20 can be guaranteed. In this case, the DU generates a rotation parameter based on the wind parameter, and the rotation parameter is to control the first antenna array 21 to rotate 90° counterclockwise.

[0129] Or, for example, when the base station 100 obtains the service parameters and wind parameters, the DU is used to generate rotation parameters according to the service parameters to ensure the communication capability of the antenna 20. For example, the service parameter is the service distribution direction angle, and the service distribution direction angle indicates that there is a large service demand directly in front of the antenna 20. The first antenna array 21 and the second antenna array 22 are located in the same plane, and the communication effect of the antenna 20 can be better. The wind parameter is the wind speed. When the wind speed is hurricane level, the first antenna array 21 and the second antenna array 22 are perpendicular, and the safety performance of the antenna 20 can be guaranteed. In this case, the DU generates the rotation parameters according to the service parameters, and the rotation parameters are to control the first antenna array 21 to rotate to the same plane as the second antenna array 22.

[0130] Or, 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 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 safety and communication capability of the antenna 20.

[0131] For example, the service parameter is the service distribution direction angle, which indicates that there is a large service demand in front of the antenna 20. The first antenna array 21 and the second antenna array 22 are located in the same plane, so that the communication effect of the antenna 20 can be better. The wind parameter is the wind speed. When the wind speed is hurricane level, the first antenna array 21 and the second antenna array 22 are perpendicular, and the safety performance of the antenna 20 can be guaranteed. In this case, the DU generates a rotation parameter based on the average value of the rotation angle corresponding to the service parameter and the rotation angle corresponding to the wind parameter. The rotation parameter is to control the first antenna array 21 to rotate counterclockwise to form an angle of 240° with the second antenna array 22.

[0132] In yet another possible implementation manner, the first parameter includes a wind parameter and a business parameter.

[0133] That is to say, 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.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] 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.

[0138] In the third case, at a certain moment, both the wind parameters and the business 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 business parameters and the wind parameters at the same time, the DU is used to select to provide the wind parameters to the antenna 20 as the first parameter for reference for the rotation of the first antenna array 21 and the second antenna array 22 in the antenna 20. Or it can be understood that when the antenna 20 needs to rotate based on the wind parameters and the business parameters at the same time, the DU only provides the wind parameters to the antenna 20, and does not provide the business parameters, so as to first ensure the safety of the antenna 20. Since the wind parameters affect the safety life, the business parameters affect the communication effect. Then, by rotating based on the wind parameters, the safety of the antenna 20 can be guaranteed first.

[0139] In the fourth case, at a certain moment, both the wind parameters and the business 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 business parameters. Then, when the base station 100 obtains the business parameters and the wind parameters, the DU is used to select to provide the business parameters to the antenna 20 as the first parameter for reference for the rotation of the first antenna array 21 and the second antenna array 22 in the antenna 20. Or it can be understood that when the antenna 20 needs to rotate based on the wind parameters and the business parameters at the same time, the DU only provides the business 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 effects, rotation based on business parameters can give priority to ensuring communication effects.

[0140] In the fifth case, at a certain moment, the first parameter includes a wind parameter and a service parameter, and the first antenna array 21 and the second antenna array 22 need to rotate based on the wind parameter and the service parameter to adjust the angle θ. For example, the first antenna array 21 and the second antenna array 22 are first rotated based on the service parameter, and then rotated based on the wind parameter. Then, the DU first provides the service parameter to the antenna 20, and then provides the wind parameter. Or, for example, the first antenna array 21 and the second antenna array 22 are first rotated based on the wind parameter, and then rotated based on the service parameter. Then, the DU first provides the wind parameter to the antenna 20, and then provides the service parameter.

[0141] However, no matter whether the first antenna array 21 and the second antenna array 22 rotate only with reference to the wind parameters, or the first antenna array 21 and the second antenna array 22 rotate only with reference to the business parameters, or the first antenna array 21 and the second antenna array 22 need to rotate with reference to both the wind parameters and the business parameters. At the same time, the first antenna array 21 and the second antenna array 22 rotate based on only one of the wind parameters and the business parameters. If the first antenna array 21 and the second antenna array 22 need to rotate with reference to both the wind parameters and the business parameters, the first antenna array 21 and the second antenna array 22 can rotate twice and then determine the angle θ.

[0142] In another possible implementation, the first parameter includes a wind parameter and a service parameter, and 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.

[0143] 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 safety and communication capability of the antenna 20 .

[0144] Or, for example, at the previous moment, the application scenario is: the wind speed is small, and the business volume directly in front is the largest. Therefore, the first antenna array 21 and the second antenna array 22 are located in the same plane, perpendicular to the 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 business parameter indicates that the business volume in the direction of 45° counterclockwise in front becomes the largest, and the direction of the first antenna array 21 needs to be rotated. At this time, DU instructs the first antenna array 21 to deflect 45° counterclockwise, and the second antenna array 22 rotates 90° clockwise to take into account both the wind force parameters and the business parameters.

[0145] In yet another possible implementation, the first parameter includes a wind parameter and a rotation parameter.

[0146] In yet another possible implementation, the first parameter includes a business parameter and a rotation parameter.

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

[0148] 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 force parameter, service parameter.

[0149] Please continue to refer to Figure 3 In a possible implementation, the first antenna array 21 and the second antenna array 22 are connected.

[0150] 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, and 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.

[0151] For example, the connecting member 23 drives the first antenna array 21 and the second antenna array 22 to rotate relative to each other according to 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.

[0152] In a possible implementation, the connecting member 23 is connected to Figure 6 The wind parameter measuring device shown is directly connected, and the wind parameter measuring device directly drives the connecting member 23 to rotate.

[0153] 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.

[0154] The connecting member 23 is used as a rotating member, and the first antenna array 21 and the second antenna array 22 are used 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.

[0155] In a 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. Such a connecting member 23 has a simple structure and high stability.

[0156] 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, the second connecting member is connected to the second antenna array 22, and 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.

[0157] For example, the first connecting member and the second connecting member may both be gears.

[0158] The connecting member 23 includes a plurality of connecting members, and the plurality of connecting members can rotate independently, which helps to realize the independent rotation of the first antenna array 21 and the second antenna array 22 .

[0159] Figure 7 A schematic diagram of the structure of an antenna provided in an embodiment of the present application.

[0160] In one possible implementation, Figure 7 As shown, the antenna 20 further includes a third antenna array 24, which includes one or more third arrays 241. The plurality of third arrays 241 are arranged, for example, in equal row spacing and equal column spacing.

[0161] The third antenna array 24 is arranged on a side of the first antenna array 21 away from the second antenna array 22 , or it can be understood that the second antenna array 22 and the third antenna array 24 are arranged on two opposite sides of the first antenna array 21 .

[0162] Of course, the structure of the third antenna array 24 may be completely the same as that of the second antenna array 22, or may be completely different. For example, the number of third arrays 241 included in the third antenna array 24 and the number of second arrays 221 included in the second antenna array 22 may be the same or different. For example, the size of the third antenna array 24 and the size of the second antenna array 22 may be the same or different.

[0163] In a first possible implementation manner, the first antenna array 21 is connected to a pole in the base station 100 .

[0164] In a possible implementation manner, 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 fixed.

[0165] In another possible implementation, the first antenna array 21 is rotatably connected to a pole in the base station 100 through a structure such as a rotating device, and the first antenna array 21 can also rotate relative to the second antenna array 22 and / or the third antenna array 24.

[0166] At the same time, optionally, the second antenna array 22 can be rotated relative to the first antenna array 21 .

[0167] Or, optionally, the third antenna array 24 can be rotated relative to the first antenna array 21.

[0168] In a second possible implementation manner, the second antenna array 22 is connected to a pole in the base station 100 .

[0169] 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 fixed.

[0170] In another possible implementation, the second antenna array 22 is rotatably connected to a pole in the base station 100 through a structure such as a rotating device, for example, and the second antenna array 22 can also rotate relative to the first antenna array 21 .

[0171] At the same time, optionally, the first antenna array 21 can be rotated relative to the second antenna array 22 .

[0172] Or, optionally, the third antenna array 24 can be rotated relative to the first antenna array 21.

[0173] In a third possible implementation manner, the third antenna array 24 is connected to a pole in the base station 100 .

[0174] In a possible implementation manner, 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 fixed.

[0175] In another possible implementation, the third antenna array 24 is rotatably connected to a pole in the base station 100 through a structure such as a rotating device, and the third antenna array 24 can also rotate relative to the first antenna array 21.

[0176] At the same time, optionally, the first antenna array 21 can be rotated relative to the third antenna array 24.

[0177] Or, optionally, the second antenna array 22 can be rotated relative to the first antenna array 21 .

[0178] 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.

[0179] For example, the first antenna array 21, the second antenna array 22 or the third antenna array 24 can all rotate.

[0180] Or, 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 .

[0181] 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 .

[0182] Figure 8-Figure 10 A schematic diagram of a beam width provided in an embodiment of the present application.

[0183] 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°).

[0184] For example, Figure 8 In the embodiment, 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 the antenna 20 is the narrowest. For example, the antenna 20 generates four narrow beams.

[0185] Fig. 9 In the embodiment, the second antenna array 22 and the third antenna array 24 are both rotated inward (in the direction of θ>180°), and the plane where the second antenna array 22 and the plane where the third antenna array 24 are located intersect with the plane where the first antenna array 21 is located respectively. The beam generated by the antenna 20 is larger than Figure 8 The angles shown generate a large beam width. For example, antenna 20 generates two medium width beams.

[0186] Fig.10 In the embodiment, the second antenna array 22 and the third antenna array 24 are Fig. 9 The second antenna array 22 and the third antenna array 24 are further rotated inwards based on the angle shown in FIG. 1 , and the plane where the second antenna array 22 and the plane where the third antenna array 24 are located intersect with the plane where the first antenna array 21 is located. The beam generated by the antenna 20 is larger than Fig. 9 The angles shown generate a wide beam. For example, antenna 20 generates a wide beam.

[0187] 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.

[0188] Fig.11 and Fig.12 A schematic diagram of the structure of an antenna provided in an embodiment of the present application.

[0189] In one possible implementation, Fig.11 As shown, the antenna 20 further includes a fourth antenna array 25, and the fourth antenna array 25 includes one or more fourth arrays 251. The plurality of fourth arrays 251 are arranged, for example, in a manner of equal row spacing and equal column spacing.

[0190] The plane where the fourth antenna array 25 is located intersects with the plane where the second antenna array 22 is located.

[0191] like Fig.11 As shown, for example, the fourth antenna array 25 and the second antenna array 22, one is located on one side of the first antenna array 21 along the row direction, and the other is located on one side of the first antenna array 21 along the column direction. For example, along the row direction, the second antenna array 22 is located on one side of the first antenna array 21. Then, along the column direction, the fourth antenna array 25 is located on one side of the first antenna array 21.

[0192] Or, if Fig.12As shown, the fourth antenna array 25 is located on one side of the second antenna array 22 .

[0193] 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.

[0194] Alternatively, for example, the first antenna array 21 is stationary, and the fourth antenna array 25 is capable of rotating relative to the first antenna array 21 .

[0195] 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 .
