Description

[0001] This application claims priority to Chinese Patent Application No. 202311640629.8, filed with the China National Intellectual Property Administration on November 30, 2023 and entitled "ANTENNA CONTROL METHOD AND COMMUNICATION APPARATUS", which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0002] This application relates to the field of communication technologies, and in particular, to an antenna control method and a communication apparatus.BACKGROUND

[0003] An antenna panel is configured to send and receive a signal, and is an important component of a communication apparatus (for example, a base station). Currently, to prevent, at various wind speeds, an antenna from being damaged, a size of the antenna panel is required to satisfy a wind resistance requirement of force-14 wind. Due to the size limitation of the antenna panel, a communication capacity and resolution cannot be further improved, and many practical requirements cannot be satisfied. For example, the base station is required to achieve vertical big-angle coverage (60° to 75°) in a communication scenario of an unmanned aerial vehicle, but the existing antenna can only implement a scanning range of ±13°; and horizontal resolution of the existing antenna lags by a factor of three behind the width of 3.5-4 m of lanes required to be distinguished by a base station antenna in a road sensing scenario. Therefore, how to improve a communication capacity and resolution while satisfying the requirement of wind resistance on the antenna is an urgent problem to be resolved currently.SUMMARY

[0004] This application provides an antenna control method and a communication apparatus, to resolve a problem of a limited communication capacity and limited resolution caused by a fixed size of an antenna panel.

[0005] According to a first aspect, an antenna control method is provided. The method may be applied to a communication apparatus. The communication apparatus includes a main antenna panel and at least one auxiliary antenna panel. The main antenna panel is in a deployed configuration.

[0006] The method includes: obtaining wind speed information; determining, based on the wind speed information, whether a configuration of the auxiliary antenna panel needs to be adjusted; and adjusting the configuration of the auxiliary antenna panel when the configuration of the auxiliary antenna panel needs to be adjusted. The configuration of the auxiliary antenna panel includes a deployed configuration and a stowed configuration. An antenna panel is in the deployed configuration when the antenna panel performs signal transmission. The antenna panel includes the main antenna panel and the auxiliary antenna panel.

[0007] For example, the communication apparatus may further include a sensor. The sensor is configured to obtain wind speed information. For example, the sensor may be arranged on the main antenna panel and / or a part or all of the at least one auxiliary antenna panel.

[0008] A current size of the antenna panel is required to satisfy a wind resistance requirement of force-14 wind. However, force-14 wind occurs only once in several decades, and the wind speed is below a force 4 for most of the time. To be specific, the communication apparatus can support an antenna panel of a larger size (or area) during most periods. According to the antenna control method provided in this application, the configuration of the auxiliary antenna panel may be flexibly adjusted based on the wind speed information, to increase a size of the antenna panel as much as possible while satisfying a requirement of wind resistance on the size of the antenna panel, further improve a communication capacity and resolution, expand a scanning range as much as possible in an integrated sensing and communication scenario, and improve sensing performance.

[0009] In a possible implementation, the method further includes: obtaining service information. The determining, based on the wind speed information, whether the configuration of the auxiliary antenna panel needs to be adjusted includes: determining, based on the wind speed information and the service information, whether the configuration of the auxiliary antenna panel needs to be adjusted.

[0010] For example, the service information may be one or more of the following: a quantity of terminals connected to the communication apparatus, a current throughput of the communication apparatus, or a current data transmission rate.

[0011] Based on the solution, the configuration of the auxiliary antenna panel is adjusted based on the wind speed information and the service information, so that the size of the antenna panel can be increased as much as possible while the current requirement on the wind speed information and the service information is satisfied. This improves a communication capacity and resolution, expands the scanning range as much as possible in the integrated sensing and communication scenario, and improves sensing performance. For example, when the wind speed is relatively low, one or more auxiliary antenna panels may be properly deployed while the service requirement is satisfied, to increase the size of the antenna panel, and improve channel capacity and resolution.

[0012] In a possible implementation, the main antenna panel is movably connected to the auxiliary antenna panel. The adjusting the configuration of the auxiliary antenna panel includes: adjusting an angle between the auxiliary antenna panel and the main antenna panel.

[0016] Based on the solution, the auxiliary antenna panel may include a plurality of sub-antenna panels, and the sub-antenna panels are movably connected, so that the size of the antenna panel can be adjusted more flexibly.

The first sub-antenna panel is connected to the main antenna panel through the telescopic component, and the second sub-antenna panel is connected to the first sub-antenna panel through the telescopic component.

[0047] This application is intended to resolve a problem of a limited communication capacity and limited resolution caused by a fixed size of an antenna panel. The solutions provided in this application are described below.

[0048] FIG. 1 is a diagram of a communication apparatus according to an embodiment of this application. The communication apparatus 100 may be the foregoing network device. However, this is not limited in this application. For example, the communication apparatus 100 may alternatively be an apparatus such as a satellite used for non-terrestrial communication. Refer to FIG. 1. The communication apparatus 100 includes a main antenna panel 11 and at least one auxiliary antenna panel 12.

[0049] The main antenna panel 11 is in a deployed configuration. The main antenna panel 11 is in the deployed configuration when performing signal transmission. In other words, the main antenna panel 11 can perform signal transmission, that is, receive and / or send a signal, only when the main antenna panel is in the deployed configuration. However, it should be understood that, this application does not impose a limitation that the main antenna panel 11 necessarily performs signal transmission when the main antenna panel 11 is in the deployed configuration. In other words, the main antenna panel 11 may alternatively not perform signal transmission when the main antenna panel 11 is in the deployed configuration.

[0050] The auxiliary antenna panel 12 includes a deployed configuration and a stowed configuration. The configuration of the auxiliary antenna panel 12 may be controlled by the communication apparatus 100. At a same moment, the auxiliary antenna panel 12 is in one of the deployed configuration and the stowed configuration. Similar to the main antenna panel 11, the auxiliary antenna panel 12 is in the deployed configuration when performing signal transmission. In addition, when the auxiliary antenna panel 12 is in the stowed configuration, the auxiliary antenna panel 12 cannot perform signal transmission. It should be understood that, this application does not impose a limitation that the auxiliary antenna panel 12 necessarily performs signal transmission when the auxiliary antenna panel 12 is in the deployed configuration. In other words, the auxiliary antenna panel 12 may alternatively not perform signal transmission when the auxiliary antenna panel 12 is in the deployed configuration.

[0051] It should be understood that a quantity of auxiliary antenna panels is not limited in this application. To be specific, the communication apparatus 100 may include any quantity of auxiliary antenna panels. In FIG. 1, three auxiliary antenna panels are used merely as an example.

[0052] It should be understood that, the deployed configuration described in this application may be a configuration of an existing or a future antenna panel for performing signal transmission or a signal operation.

[0053] For example, in the deployed configuration, the auxiliary antenna panel 12 and the main antenna panel 11 are on a same plane, or an angle between the auxiliary antenna panel 12 and the main antenna panel 11 is 0 degrees or approximates 0 degrees.

[0054] For example, when the auxiliary antenna panel 12 is in the stowed configuration, the main antenna panel 11 is perpendicular to the auxiliary antenna panel 12, or the auxiliary antenna panel 12 is located directly behind the main antenna panel 11.

[0055] For example, FIG. 2(a) to FIG. 2(h) show diagrams of relative position relationships between the auxiliary antenna panel 12 and the main antenna panel 11 when the auxiliary antenna panel 12 is in the deployed configuration and the stowed configuration. FIG. 2(a) to FIG. 2(d) respectively show diagrams of position relationships between the auxiliary antenna panel 12 in the deployed configuration and the main antenna panel 11. FIG. 2(e) to FIG. 2(h) successively show diagrams of relative position relationships between the auxiliary antenna panel 12 in the stowed configuration in FIG. 2(a) to FIG. 2(d) and the main antenna panel 11. It should be understood that, if the auxiliary antenna panel 12 shown in FIG. 2(e) is defined as being located at the left rear of the main antenna panel 11, the auxiliary antenna panel 12 shown in FIG. 2(f) is located at the right rear of the main antenna panel 11; and if the auxiliary antenna panel 12 shown in FIG. 2(g) is defined as being located at the upper rear of the main antenna panel 11, the auxiliary antenna panel 12 shown in FIG. 2(h) is located at the lower rear of the main antenna panel 11. It should be further understood that, the auxiliary antenna panel 12 in the stowed configuration in FIG. 2(a) to FIG. 2(d) may also be located directly behind the main antenna panel 11. It should be understood that, a magnitude relationship between a size of the auxiliary antenna panel 12 and a size of the main antenna panel 11 is not limited in this application, and a magnitude relationship between sizes of a plurality of auxiliary antenna panels 12 is also not limited when the communication apparatus 100 includes the plurality of auxiliary antenna panels 12, where the sizes of the plurality of the auxiliary antenna panels 12 may be the same or different.

[0056] For example, an example in which the communication apparatus 100 includes three auxiliary antenna panels is used. FIG. 3(a) to FIG. 3(d) show diagrams of possible forms of an antenna panel of the communication apparatus. In FIG. 3(a), the three auxiliary antenna panels 12 are all in a stowed configuration. In FIG. 3(b), one auxiliary antenna panel 12 is in a deployed configuration, and two auxiliary antenna panels 12 are in a stowed configuration. In FIG. 3(c), two auxiliary antenna panels 12 are in a deployed configuration, and one auxiliary antenna panel 12 is in a stowed configuration. In FIG. 3(d), the three auxiliary antenna panels 12 are all in a deployed configuration.

[0057] In some embodiments, the auxiliary antenna panel 12 may be directly or indirectly connected to the main antenna panel 11.

[0058] In a possible implementation, the auxiliary antenna panel 12 is movably connected (or referred to as rotatably connected) to the main antenna panel 11. In the manner, the auxiliary antenna panel is movably connected to the main antenna panel, so that the configuration of the auxiliary antenna panel is adjusted by adjusting the angle (that is, an included angle) between the main antenna panel and the auxiliary antenna panel, to adjust a size (an equivalent size) of an antenna panel.

[0059] For example, the auxiliary antenna panel 12 may be connected to the main antenna panel 11 through a component that supports 360-degree or 180-degree free movement.

[0060] For example, refer to FIG. 4. The auxiliary antenna panel 12 may be connected to the main antenna panel 11 through a shaft 101, and the auxiliary antenna panel 12 may achieve 360-degree free rotation about the shaft 101 that connects the main antenna panel 11. The communication apparatus 100 may control, by controlling rotation of the shaft 101, the auxiliary antenna panel 12 to be in the stowed configuration or the deployed configuration.

[0061] It should be noted that, the component that connects the auxiliary antenna panel 12 and the main antenna panel 11 is not limited in this application, provided that the included angle between the auxiliary antenna panel 12 and the main antenna panel 11 can be adjusted. In addition, an adjustable angle between the auxiliary antenna panel 12 and the main antenna panel 11 is not limited in this application. For example, the angle may be 360 degrees or 180 degrees, or may be 90 degrees.

[0062] In a possible implementation, the auxiliary antenna panel 12 is connected to the main antenna panel 11 through a telescopic component.

[0063] In the solution, a telescopic length of the auxiliary antenna panel 12 relative to the main antenna panel 11 may be controlled by controlling the telescopic component, so that the auxiliary antenna panel is in the deployed configuration or in the stowed configuration. In other words, according to the solution, the configuration of the auxiliary antenna panel can be adjusted by controlling the telescopic length of the auxiliary antenna panel 12 relative to the main antenna panel 11, to adjust a size (an equivalent size) of an antenna panel.

[0064] For example, when the telescopic length of the auxiliary antenna panel 12 relative to the main antenna panel 11 is 0, the main antenna panel 11 completely occludes the auxiliary antenna panel 12. In this case, the auxiliary antenna panel 12 is in the stowed configuration. When the telescopic length of the auxiliary antenna panel 12 relative to the main antenna panel 11 is a maximum telescopic length, a relative position relationship between the auxiliary antenna panel 12 and the main antenna panel 11 may be as shown in any one of the accompanying drawings in FIG. 2(a) to FIG. 2(h).

[0065] In a possible implementation, refer to FIG. 5. The auxiliary antenna panel 12 includes a first sub-antenna panel 121 and a second sub-antenna panel 122. The first sub-antenna panel 121 is movably connected to the main antenna panel 11 or the first sub-antenna panel 121 is connected to the main antenna panel 11 through a telescopic component, and the second sub-antenna panel 122 is movably connected to the first sub-antenna panel 121 or the second sub-antenna panel 122 is connected to the first sub-antenna panel 121 through a telescopic component.

[0066] Regarding connection forms between the first sub-antenna panel 121 and the main antenna panel 11 and between the first sub-antenna panel 121 and the second sub-antenna panel 122, refer to the foregoing manner of a connection between the auxiliary antenna panel 12 and the main antenna panel 11. Details are not described herein again.

[0067] For example, refer to FIG. 6. The first sub-antenna panel 121 may be connected to the main antenna panel 11 through a shaft 101, and the auxiliary antenna panel 12 may achieve 360-degree free rotation about the shaft 101. The second sub-antenna panel 122 may be connected to the first sub-antenna panel 121 through a shaft 102, and the second sub-antenna panel 122 may achieve 360-degree free rotation about the shaft 102. The communication apparatus 100 may control, by controlling rotation of the shaft 101, the first sub-antenna panel 121 to be in the stowed configuration or the deployed configuration, and may control, by controlling rotation of the shaft 102, the second sub-antenna panel 122 to be in the stowed configuration or the deployed configuration.

[0068] It should be noted that, sizes of the first sub-antenna panel and the second sub-antenna panel are not limited in this application, and the size of the first sub-antenna panel may be the same as or different from that of the second sub-antenna panel.

[0069] In some embodiments, the communication apparatus 100 may further include a driving assembly 13. The driving assembly 13 drives the component that connects the auxiliary antenna panel 12 and the main antenna panel 11 to change the configuration of the auxiliary antenna panel 12.

[0070] For example, the driving assembly 13 may be a motor. For example, the motor may drive the shaft 101 shown in FIG. 4 or drive the telescopic component described above.

[0071] In some embodiments, a sensor is arranged on the main antenna panel 11 and / or a part or all of the at least one auxiliary antenna panel 12. The sensor is configured to collect wind speed information. For example, the sensor may be a wind speed sensor.

[0072] For example, refer to FIG. 1. A sensor 111 may be arranged on the main antenna panel 11. It should be understood that the sensor may be arranged on the main antenna panel 11 and a part or all of the auxiliary antenna panel 12, or the sensor may be arranged on a part or all of the auxiliary antenna panel 12.

[0073] The method provided in this application is described below with reference to the communication apparatus 100 described above. It should be understood that, the method provided in this application may be performed by the foregoing communication apparatus 100 or a module, a chip, a computer program, or the like arranged in the communication apparatus 100. An example in which the method is performed by the communication apparatus 100 is used for description below.

[0074] FIG. 7 is a schematic flowchart of an antenna control method according to this application. The method 200 includes S210 to S230, and each step is described below.

[0075] S210: A communication apparatus obtains wind speed information.

[0076] For example, as described above, a sensor may be arranged on the main antenna panel and / or a part or all of the at least one auxiliary antenna panel, and the sensor may collect the wind speed information. For example, the sensor is a wind speed sensor.

[0077] For example, the wind speed information may be wind speed-related information obtained by processing information collected by the sensor.

[0078] In an example, the communication apparatus may periodically obtain the wind speed information. For example, the sensor may periodically obtain the wind speed information.

[0079] In an example, if wind speed information currently obtained by the sensor is different from wind speed information obtained last time, the wind speed information is reported to the communication apparatus.

[0080] For example, the wind speed information may be a wind speed force, information related to the wind speed force, or any information that can represent a wind speed.

[0081] S220: The communication apparatus determines, based on the wind speed information, whether a configuration of an auxiliary antenna panel needs to be adjusted.

[0082] For example, the communication apparatus may store a correspondence between the wind speed information and a configuration of an antenna panel, and the communication apparatus may determine, depending on whether a current configuration of the antenna panel is a target configuration corresponding to the wind speed information, whether to adjust the configuration of the auxiliary antenna panel. If the current configuration of the antenna panel is not the target configuration corresponding to the wind speed information, the configuration of the auxiliary antenna panel needs to be adjusted; otherwise, the configuration of the auxiliary antenna panel does not need to be adjusted. Adjusting the configuration of the auxiliary antenna panel is adjusting a configuration of a part or all of the at least one auxiliary antenna panel.

[0083] For example, S220 is performed only when the wind speed information changes. To be specific, S220 is performed only when the currently obtained wind speed information is different from the wind speed information obtained last time.

[0084] S230: The communication apparatus adjusts the configuration of the auxiliary antenna panel when it is determined that the configuration of the auxiliary antenna panel needs to be adjusted.

[0085] For example, if it is determined in S220 that the configuration of the auxiliary antenna panel needs to be adjusted, the configuration of a part or all of the at least one auxiliary antenna panel is adjusted, so that the configuration of the antenna panel after adjustment is the target configuration corresponding to the wind speed information. If it is determined in S220 that the configuration of the auxiliary antenna panel does not need to be adjusted, no operation may be performed.

[0086] An example in which the communication apparatus includes a main antenna panel 11 and three auxiliary antenna panels 12A, 12B, and 12C, and the auxiliary antenna panels 12A, 12B, and 12C in a deployed state are respectively located above, on the left, and on the right of the main antenna panel 11 is used for description.

[0087] In an example, refer to FIG. 8(a). When the wind speed force is any one of forces 11-14, no auxiliary antenna panel needs to be deployed. To be specific, the target configuration is that only the main antenna panel 11 is in the deployed state. Refer to FIG. 8(b). When the wind speed force is any one of forces 8-10, the auxiliary antenna panel 12A may be deployed. To be specific, the target configuration is that the main antenna panel 11 and the auxiliary antenna panel 12A (or any auxiliary antenna panel or an auxiliary antenna panel in a specific direction) are in the deployed state. Refer to FIG. 8(c). When the wind speed force is any one of forces 4-7, the auxiliary antenna panels 12A and 12B may be deployed. To be specific, the target configuration is that the main antenna panel 11 and the auxiliary antenna panels 12A and 12B (or any two auxiliary antenna panels or auxiliary antenna panels in specific directions) are in the deployed state. Refer to FIG. 8(d). When the wind speed force is any one of forces below a force 4 (that is, forces 0-3), the auxiliary antenna panels 12A, 12B, and 12C may be deployed. To be specific, the target configuration is that the main antenna panel 11 and all the auxiliary antenna panels are all in the deployed state.

[0088] In another example, refer to FIG. 9(a). When the wind speed force is a force 13 or 14, no auxiliary antenna panel needs to be deployed. Refer to FIG. 9(b). When the wind speed force is any one of forces 8-12, the auxiliary antenna panel 12A may be deployed. Refer to FIG. 9(c). When the wind speed force is any one of forces below a force 8 (that is, forces 0-7), the auxiliary antenna panels 12A, 12B, and 12C may be deployed.

[0089] An example in which the communication apparatus includes a main antenna panel 11 and two auxiliary antenna panels 12A and 12B, and the two auxiliary antenna panels each include the first sub-antenna panel and the second sub-antenna panel described above is used for description. In an example, refer to FIG. 10(a). When the wind speed force is a force 13 or 14, no auxiliary antenna panel needs to be deployed. Refer to FIG. 10(b). When the wind speed force is any one of forces 8-12, a first sub-antenna panel 121A in the auxiliary antenna panel 12A and a first sub-antenna panel 122A in the auxiliary antenna panel 12B may be deployed. Refer to FIG. 10(c). When the wind speed force is any one of forces below a force 8 (that is, forces 0-7), a first sub-antenna panel 121A and a second sub-antenna panel 121B in the auxiliary antenna panel 12A and a first sub-antenna panel 122A and a second sub-antenna panel 122B in the auxiliary antenna panel 12B may be deployed.

[0090] A current size of an antenna panel is required to satisfy wind resistance of force-14 wind. However, force-14 wind occurs only once in several decades, and the wind speed is below a force 4 for most of the time. To be specific, the communication apparatus can support an antenna panel of a larger size (or area) during most periods. According to the antenna control method provided in this application, the configuration of the auxiliary antenna panel may be flexibly adjusted based on the wind speed information, to increase a size of the antenna panel as much as possible while satisfying a requirement of wind resistance on the size of the antenna panel, further improve a communication capacity and resolution, expand a scanning range as much as possible in an integrated sensing and communication scenario, and improve sensing performance.

[0091] It should be understood that, for the auxiliary antenna panel, the main antenna panel, and how to adjust the configuration of the auxiliary antenna panel, refer to the related descriptions in the descriptions of the communication apparatus 100. Details are not described herein again.

[0092] In some embodiments, before S220, the method further includes: The communication apparatus obtains service information. Correspondingly, in S220, the communication apparatus determines, based on the obtained wind speed information and service information, whether the configuration of the auxiliary antenna panel needs to be adjusted.

[0093] For example, the service information may be one or more of the following: a quantity of terminals connected to the communication apparatus, a current throughput of the communication apparatus, or a current data transmission rate.

[0094] For example, when the wind speed force is any one of forces below a force 7, if the current data transmission rate is less than a preset threshold #1, all auxiliary antenna panels may be deployed. For example, when the wind speed force is any one of forces below a force 4, if the quantity of terminals connected to the communication apparatus is greater than a preset threshold #2, all auxiliary antenna panels may be deployed. When the wind speed force is any one of forces below a force 7, if the quantity of terminals connected to the communication apparatus is greater than a preset threshold #3, some auxiliary antenna panels may be deployed.

[0095] According to the antenna control method provided in this application, the configuration of the auxiliary antenna panel is adjusted based on the wind speed information and the service information, so that the size of the antenna panel can be increased as much as possible while satisfying current requirements of the wind speed information and the service information, to improve a communication capacity and resolution, expand a scanning range as much as possible in the integrated sensing and communication scenario, and improve sensing performance. For example, when the wind speed is low, one or more auxiliary antenna panels may be properly deployed while satisfying a service requirement, to increase the size of the antenna panel, and improve a channel capacity and resolution.

[0001] This application claims priority to Chinese Patent Application No. 202311640629.8, filed with the China National Intellectual Property Administration on November 30, 2023 and entitled "ANTENNA CONTROL METHOD AND COMMUNICATION APPARATUS", which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0002] This application relates to the field of communication technologies, and in particular, to an antenna control method and a communication apparatus.BACKGROUND

[0003] An antenna panel is configured to send and receive a signal, and is an important component of a communication apparatus (for example, a base station). Currently, to prevent, at various wind speeds, an antenna from being damaged, a size of the antenna panel is required to satisfy a wind resistance requirement of force-14 wind. Due to the size limitation of the antenna panel, a communication capacity and resolution cannot be further improved, and many practical requirements cannot be satisfied. For example, the base station is required to achieve vertical big-angle coverage (60° to 75°) in a communication scenario of an unmanned aerial vehicle, but the existing antenna can only implement a scanning range of ±13°; and horizontal resolution of the existing antenna lags by a factor of three behind the width of 3.5-4 m of lanes required to be distinguished by a base station antenna in a road sensing scenario. Therefore, how to improve a communication capacity and resolution while satisfying the requirement of wind resistance on the antenna is an urgent problem to be resolved currently.SUMMARY

[0004] This application provides an antenna control method and a communication apparatus, to resolve a problem of a limited communication capacity and limited resolution caused by a fixed size of an antenna panel.

[0005] According to a first aspect, an antenna control method is provided. The method may be applied to a communication apparatus. The communication apparatus includes a main antenna panel and at least one auxiliary antenna panel. The main antenna panel is in a deployed configuration.

[0006] The method includes: obtaining wind speed information; determining, based on the wind speed information, whether a configuration of the auxiliary antenna panel needs to be adjusted; and adjusting the configuration of the auxiliary antenna panel when the configuration of the auxiliary antenna panel needs to be adjusted. The configuration of the auxiliary antenna panel includes a deployed configuration and a stowed configuration. An antenna panel is in the deployed configuration when the antenna panel performs signal transmission. The antenna panel includes the main antenna panel and the auxiliary antenna panel.

[0007] For example, the communication apparatus may further include a sensor. The sensor is configured to obtain wind speed information. For example, the sensor may be arranged on the main antenna panel and / or a part or all of the at least one auxiliary antenna panel.

[0008] A current size of the antenna panel is required to satisfy a wind resistance requirement of force-14 wind. However, force-14 wind occurs only once in several decades, and the wind speed is below a force 4 for most of the time. To be specific, the communication apparatus can support an antenna panel of a larger size (or area) during most periods. According to the antenna control method provided in this application, the configuration of the auxiliary antenna panel may be flexibly adjusted based on the wind speed information, to increase a size of the antenna panel as much as possible while satisfying a requirement of wind resistance on the size of the antenna panel, further improve a communication capacity and resolution, expand a scanning range as much as possible in an integrated sensing and communication scenario, and improve sensing performance.

[0009] In a possible implementation, the method further includes: obtaining service information. The determining, based on the wind speed information, whether the configuration of the auxiliary antenna panel needs to be adjusted includes: determining, based on the wind speed information and the service information, whether the configuration of the auxiliary antenna panel needs to be adjusted.

[0010] For example, the service information may be one or more of the following: a quantity of terminals connected to the communication apparatus, a current throughput of the communication apparatus, or a current data transmission rate.

[0011] Based on the solution, the configuration of the auxiliary antenna panel is adjusted based on the wind speed information and the service information, so that the size of the antenna panel can be increased as much as possible while the current requirement on the wind speed information and the service information is satisfied. This improves a communication capacity and resolution, expands the scanning range as much as possible in the integrated sensing and communication scenario, and improves sensing performance. For example, when the wind speed is relatively low, one or more auxiliary antenna panels may be properly deployed while the service requirement is satisfied, to increase the size of the antenna panel, and improve channel capacity and resolution.

[0012] In a possible implementation, the main antenna panel is movably connected to the auxiliary antenna panel. The adjusting the configuration of the auxiliary antenna panel includes: adjusting an angle between the auxiliary antenna panel and the main antenna panel.

[0013] Based on the solution, the configuration of the auxiliary antenna panel is adjusted by adjusting the angle (that is, an included angle) between the main antenna panel and the auxiliary antenna panel, to implement the adjustment of the size (an equivalent size) of the antenna panel.

[0016] Based on the solution, the auxiliary antenna panel may include a plurality of sub-antenna panels, and the sub-antenna panels are movably connected, so that the size of the antenna panel can be adjusted more flexibly.

[0017] In a possible implementation, the second sub-antenna panel is connected to the first sub-antenna panel through a component that supports a 360-degree or 180-degree free movement.

[0020] In a possible implementation, the auxiliary antenna panel includes the first sub-antenna panel and the second sub-antenna panel. The first sub-antenna panel is connected to the main antenna panel through the telescopic component, and the second sub-antenna panel is connected to the first sub-antenna panel through the telescopic component.

[0021] Based on the solution, the auxiliary antenna panel may include a plurality of sub-antenna panels, and the sub-antenna panels are connected through the telescopic component, so that the size of the antenna panel can be adjusted more flexibly.

[0047] This application is intended to resolve a problem of a limited communication capacity and limited resolution caused by a fixed size of an antenna panel. The solutions provided in this application are described below.

[0048] FIG. 1 is a diagram of a communication apparatus according to an embodiment of this application. The communication apparatus 100 may be the foregoing network device. However, this is not limited in this application. For example, the communication apparatus 100 may alternatively be an apparatus such as a satellite used for non-terrestrial communication. Refer to FIG. 1. The communication apparatus 100 includes a main antenna panel 11 and at least one auxiliary antenna panel 12.

[0049] The main antenna panel 11 is in a deployed configuration. The main antenna panel 11 is in the deployed configuration when performing signal transmission. In other words, the main antenna panel 11 can perform signal transmission, that is, receive and / or send a signal, only when the main antenna panel is in the deployed configuration. However, it should be understood that, this application does not impose a limitation that the main antenna panel 11 necessarily performs signal transmission when the main antenna panel 11 is in the deployed configuration. In other words, the main antenna panel 11 may alternatively not perform signal transmission when the main antenna panel 11 is in the deployed configuration.

[0050] The auxiliary antenna panel 12 includes a deployed configuration and a stowed configuration. The configuration of the auxiliary antenna panel 12 may be controlled by the communication apparatus 100. At a same moment, the auxiliary antenna panel 12 is in one of the deployed configuration and the stowed configuration. Similar to the main antenna panel 11, the auxiliary antenna panel 12 is in the deployed configuration when performing signal transmission. In addition, when the auxiliary antenna panel 12 is in the stowed configuration, the auxiliary antenna panel 12 cannot perform signal transmission. It should be understood that, this application does not impose a limitation that the auxiliary antenna panel 12 necessarily performs signal transmission when the auxiliary antenna panel 12 is in the deployed configuration. In other words, the auxiliary antenna panel 12 may alternatively not perform signal transmission when the auxiliary antenna panel 12 is in the deployed configuration.

[0051] It should be understood that a quantity of auxiliary antenna panels is not limited in this application. To be specific, the communication apparatus 100 may include any quantity of auxiliary antenna panels. In FIG. 1, three auxiliary antenna panels are used merely as an example.

[0052] It should be understood that, the deployed configuration described in this application may be a configuration of an existing or a future antenna panel for performing signal transmission or a signal operation.

[0053] For example, in the deployed configuration, the auxiliary antenna panel 12 and the main antenna panel 11 are on a same plane, or an angle between the auxiliary antenna panel 12 and the main antenna panel 11 is 0 degrees or approximates 0 degrees.

[0054] For example, when the auxiliary antenna panel 12 is in the stowed configuration, the main antenna panel 11 is perpendicular to the auxiliary antenna panel 12, or the auxiliary antenna panel 12 is located directly behind the main antenna panel 11.

[0055] For example, FIG. 2(a) to FIG. 2(h) show diagrams of relative position relationships between the auxiliary antenna panel 12 and the main antenna panel 11 when the auxiliary antenna panel 12 is in the deployed configuration and the stowed configuration. FIG. 2(a) to FIG. 2(d) respectively show diagrams of position relationships between the auxiliary antenna panel 12 in the deployed configuration and the main antenna panel 11. FIG. 2(e) to FIG. 2(h) successively show diagrams of relative position relationships between the auxiliary antenna panel 12 in the stowed configuration in FIG. 2(a) to FIG. 2(d) and the main antenna panel 11. It should be understood that, if the auxiliary antenna panel 12 shown in FIG. 2(e) is defined as being located at the left rear of the main antenna panel 11, the auxiliary antenna panel 12 shown in FIG. 2(f) is located at the right rear of the main antenna panel 11; and if the auxiliary antenna panel 12 shown in FIG. 2(g) is defined as being located at the upper rear of the main antenna panel 11, the auxiliary antenna panel 12 shown in FIG. 2(h) is located at the lower rear of the main antenna panel 11. It should be further understood that, the auxiliary antenna panel 12 in the stowed configuration in FIG. 2(a) to FIG. 2(d) may also be located directly behind the main antenna panel 11. It should be understood that, a magnitude relationship between a size of the auxiliary antenna panel 12 and a size of the main antenna panel 11 is not limited in this application, and a magnitude relationship between sizes of a plurality of auxiliary antenna panels 12 is also not limited when the communication apparatus 100 includes the plurality of auxiliary antenna panels 12, where the sizes of the plurality of the auxiliary antenna panels 12 may be the same or different.

[0056] For example, an example in which the communication apparatus 100 includes three auxiliary antenna panels is used. FIG. 3(a) to FIG. 3(d) show diagrams of possible forms of an antenna panel of the communication apparatus. In FIG. 3(a), the three auxiliary antenna panels 12 are all in a stowed configuration. In FIG. 3(b), one auxiliary antenna panel 12 is in a deployed configuration, and two auxiliary antenna panels 12 are in a stowed configuration. In FIG. 3(c), two auxiliary antenna panels 12 are in a deployed configuration, and one auxiliary antenna panel 12 is in a stowed configuration. In FIG. 3(d), the three auxiliary antenna panels 12 are all in a deployed configuration.

[0057] In some embodiments, the auxiliary antenna panel 12 may be directly or indirectly connected to the main antenna panel 11.

[0058] In a possible implementation, the auxiliary antenna panel 12 is movably connected (or referred to as rotatably connected) to the main antenna panel 11. In the manner, the auxiliary antenna panel is movably connected to the main antenna panel, so that the configuration of the auxiliary antenna panel is adjusted by adjusting the angle (that is, an included angle) between the main antenna panel and the auxiliary antenna panel, to adjust a size (an equivalent size) of an antenna panel.

[0059] For example, the auxiliary antenna panel 12 may be connected to the main antenna panel 11 through a component that supports 360-degree or 180-degree free movement.

[0060] For example, refer to FIG. 4. The auxiliary antenna panel 12 may be connected to the main antenna panel 11 through a shaft 101, and the auxiliary antenna panel 12 may achieve 360-degree free rotation about the shaft 101 that connects the main antenna panel 11. The communication apparatus 100 may control, by controlling rotation of the shaft 101, the auxiliary antenna panel 12 to be in the stowed configuration or the deployed configuration.

[0061] It should be noted that, the component that connects the auxiliary antenna panel 12 and the main antenna panel 11 is not limited in this application, provided that the included angle between the auxiliary antenna panel 12 and the main antenna panel 11 can be adjusted. In addition, an adjustable angle between the auxiliary antenna panel 12 and the main antenna panel 11 is not limited in this application. For example, the angle may be 360 degrees or 180 degrees, or may be 90 degrees.

[0062] In a possible implementation, the auxiliary antenna panel 12 is connected to the main antenna panel 11 through a telescopic component.

[0063] In the solution, a telescopic length of the auxiliary antenna panel 12 relative to the main antenna panel 11 may be controlled by controlling the telescopic component, so that the auxiliary antenna panel is in the deployed configuration or in the stowed configuration. In other words, according to the solution, the configuration of the auxiliary antenna panel can be adjusted by controlling the telescopic length of the auxiliary antenna panel 12 relative to the main antenna panel 11, to adjust a size (an equivalent size) of an antenna panel.

[0064] For example, when the telescopic length of the auxiliary antenna panel 12 relative to the main antenna panel 11 is 0, the main antenna panel 11 completely occludes the auxiliary antenna panel 12. In this case, the auxiliary antenna panel 12 is in the stowed configuration. When the telescopic length of the auxiliary antenna panel 12 relative to the main antenna panel 11 is a maximum telescopic length, a relative position relationship between the auxiliary antenna panel 12 and the main antenna panel 11 may be as shown in any one of the accompanying drawings in FIG. 2(a) to FIG. 2(h).

[0065] In a possible implementation, refer to FIG. 5. The auxiliary antenna panel 12 includes a first sub-antenna panel 121 and a second sub-antenna panel 122. The first sub-antenna panel 121 is movably connected to the main antenna panel 11 or the first sub-antenna panel 121 is connected to the main antenna panel 11 through a telescopic component, and the second sub-antenna panel 122 is movably connected to the first sub-antenna panel 121 or the second sub-antenna panel 122 is connected to the first sub-antenna panel 121 through a telescopic component.

[0066] Regarding connection forms between the first sub-antenna panel 121 and the main antenna panel 11 and between the first sub-antenna panel 121 and the second sub-antenna panel 122, refer to the foregoing manner of a connection between the auxiliary antenna panel 12 and the main antenna panel 11. Details are not described herein again.

[0067] For example, refer to FIG. 6.

[0068] It should be noted that, sizes of the first sub-antenna panel and the second sub-antenna panel are not limited in this application, and the size of the first sub-antenna panel may be the same as or different from that of the second sub-antenna panel.

[0069] In some embodiments, the communication apparatus 100 may further include a driving assembly 13. The driving assembly 13 drives the component that connects the auxiliary antenna panel 12 and the main antenna panel 11 to change the configuration of the auxiliary antenna panel 12.

[0070] For example, the driving assembly 13 may be a motor. For example, the motor may drive the shaft 101 shown in FIG. 4 or drive the telescopic component described above.

[0071] In some embodiments, a sensor is arranged on the main antenna panel 11 and / or a part or all of the at least one auxiliary antenna panel 12. The sensor is configured to collect wind speed information. For example, the sensor may be a wind speed sensor.

[0072] For example, refer to FIG. 1. A sensor 111 may be arranged on the main antenna panel 11. It should be understood that the sensor may be arranged on the main antenna panel 11 and a part or all of the auxiliary antenna panel 12, or the sensor may be arranged on a part or all of the auxiliary antenna panel 12.

[0073] The method provided in this application is described below with reference to the communication apparatus 100 described above. It should be understood that, the method provided in this application may be performed by the foregoing communication apparatus 100 or a module, a chip, a computer program, or the like arranged in the communication apparatus 100. An example in which the method is performed by the communication apparatus 100 is used for description below.

[0074] FIG. 7 is a schematic flowchart of an antenna control method according to this application. The method 200 includes S210 to S230, and each step is described below.

[0075] S210: A communication apparatus obtains wind speed information.

[0076] For example, as described above, a sensor may be arranged on the main antenna panel and / or a part or all of the at least one auxiliary antenna panel, and the sensor may collect the wind speed information. For example, the sensor is a wind speed sensor.

[0077] For example, the wind speed information may be wind speed-related information obtained by processing information collected by the sensor.

[0078] In an example, the communication apparatus may periodically obtain the wind speed information. For example, the sensor may periodically obtain the wind speed information.

[0079] In an example, if wind speed information currently obtained by the sensor is different from wind speed information obtained last time, the wind speed information is reported to the communication apparatus.

[0080] For example, the wind speed information may be a wind speed force, information related to the wind speed force, or any information that can represent a wind speed.

[0081] S220: The communication apparatus determines, based on the wind speed information, whether a configuration of an auxiliary antenna panel needs to be adjusted.

[0082] For example, the communication apparatus may store a correspondence between the wind speed information and a configuration of an antenna panel, and the communication apparatus may determine, depending on whether a current configuration of the antenna panel is a target configuration corresponding to the wind speed information, whether to adjust the configuration of the auxiliary antenna panel. If the current configuration of the antenna panel is not the target configuration corresponding to the wind speed information, the configuration of the auxiliary antenna panel needs to be adjusted; otherwise, the configuration of the auxiliary antenna panel does not need to be adjusted. Adjusting the configuration of the auxiliary antenna panel is adjusting a configuration of a part or all of the at least one auxiliary antenna panel.

[0083] For example, S220 is performed only when the wind speed information changes. To be specific, S220 is performed only when the currently obtained wind speed information is different from the wind speed information obtained last time.

[0084] S230: The communication apparatus adjusts the configuration of the auxiliary antenna panel when it is determined that the configuration of the auxiliary antenna panel needs to be adjusted.

[0085] For example, if it is determined in S220 that the configuration of the auxiliary antenna panel needs to be adjusted, the configuration of a part or all of the at least one auxiliary antenna panel is adjusted, so that the configuration of the antenna panel after adjustment is the target configuration corresponding to the wind speed information. If it is determined in S220 that the configuration of the auxiliary antenna panel does not need to be adjusted, no operation may be performed.

[0086] An example in which the communication apparatus includes a main antenna panel 11 and three auxiliary antenna panels 12A, 12B, and 12C, and the auxiliary antenna panels 12A, 12B, and 12C in a deployed state are respectively located above, on the left, and on the right of the main antenna panel 11 is used for description.

[0087] In an example, refer to FIG. 8(a). When the wind speed force is any one of forces 11-14, no auxiliary antenna panel needs to be deployed. To be specific, the target configuration is that only the main antenna panel 11 is in the deployed state. Refer to FIG. 8(b). When the wind speed force is any one of forces 8-10, the auxiliary antenna panel 12A may be deployed. To be specific, the target configuration is that the main antenna panel 11 and the auxiliary antenna panel 12A (or any auxiliary antenna panel or an auxiliary antenna panel in a specific direction) are in the deployed state. Refer to FIG. 8(c). When the wind speed force is any one of forces 4-7, the auxiliary antenna panels 12A and 12B may be deployed. To be specific, the target configuration is that the main antenna panel 11 and the auxiliary antenna panels 12A and 12B (or any two auxiliary antenna panels or auxiliary antenna panels in specific directions) are in the deployed state. Refer to FIG. 8(d). When the wind speed force is any one of forces below a force 4 (that is, forces 0-3), the auxiliary antenna panels 12A, 12B, and 12C may be deployed. To be specific, the target configuration is that the main antenna panel 11 and all the auxiliary antenna panels are all in the deployed state.

[0088] In another example, refer to FIG. 9(a). When the wind speed force is a force 13 or 14, no auxiliary antenna panel needs to be deployed. Refer to FIG. 9(b). When the wind speed force is any one of forces 8-12, the auxiliary antenna panel 12A may be deployed. Refer to FIG. 9(c). When the wind speed force is any one of forces below a force 8 (that is, forces 0-7), the auxiliary antenna panels 12A, 12B, and 12C may be deployed.

[0089] An example in which the communication apparatus includes a main antenna panel 11 and two auxiliary antenna panels 12A and 12B, and the two auxiliary antenna panels each include the first sub-antenna panel and the second sub-antenna panel described above is used for description. In an example, refer to FIG. 10(a). When the wind speed force is a force 13 or 14, no auxiliary antenna panel needs to be deployed. Refer to FIG. 10(b). When the wind speed force is any one of forces 8-12, a first sub-antenna panel 121A in the auxiliary antenna panel 12A and a first sub-antenna panel 122A in the auxiliary antenna panel 12B may be deployed. Refer to FIG. 10(c). When the wind speed force is any one of forces below a force 8 (that is, forces 0-7), a first sub-antenna panel 121A and a second sub-antenna panel 121B in the auxiliary antenna panel 12A and a first sub-antenna panel 122A and a second sub-antenna panel 122B in the auxiliary antenna panel 12B may be deployed.

[0090] A current size of an antenna panel is required to satisfy wind resistance of force-14 wind. However, force-14 wind occurs only once in several decades, and the wind speed is below a force 4 for most of the time. To be specific, the communication apparatus can support an antenna panel of a larger size (or area) during most periods. According to the antenna control method provided in this application, the configuration of the auxiliary antenna panel may be flexibly adjusted based on the wind speed information, to increase a size of the antenna panel as much as possible while satisfying a requirement of wind resistance on the size of the antenna panel, further improve a communication capacity and resolution, expand a scanning range as much as possible in an integrated sensing and communication scenario, and improve sensing performance.

[0091] It should be understood that, for the auxiliary antenna panel, the main antenna panel, and how to adjust the configuration of the auxiliary antenna panel, refer to the related descriptions in the descriptions of the communication apparatus 100. Details are not described herein again.

[0092] In some embodiments, before S220, the method further includes: The communication apparatus obtains service information. Correspondingly, in S220, the communication apparatus determines, based on the obtained wind speed information and service information, whether the configuration of the auxiliary antenna panel needs to be adjusted.

[0093] For example, the service information may be one or more of the following: a quantity of terminals connected to the communication apparatus, a current throughput of the communication apparatus, or a current data transmission rate.

[0094] For example, when the wind speed force is any one of forces below a force 7, if the current data transmission rate is less than a preset threshold #1, all auxiliary antenna panels may be deployed. For example, when the wind speed force is any one of forces below a force 4, if the quantity of terminals connected to the communication apparatus is greater than a preset threshold #2, all auxiliary antenna panels may be deployed. When the wind speed force is any one of forces below a force 7, if the quantity of terminals connected to the communication apparatus is greater than a preset threshold #3, some auxiliary antenna panels may be deployed.

[0095] According to the antenna control method provided in this application, the configuration of the auxiliary antenna panel is adjusted based on the wind speed information and the service information, so that the size of the antenna panel can be increased as much as possible while satisfying current requirements of the wind speed information and the service information, to improve a communication capacity and resolution, expand a scanning range as much as possible in the integrated sensing and communication scenario, and improve sensing performance. For example, when the wind speed is low, one or more auxiliary antenna panels may be properly deployed while satisfying a service requirement, to increase the size of the antenna panel, and improve a channel capacity and resolution.

[0096] The communication method provided in this application is described above. Some communication apparatuses provided in this application are described below with reference to the foregoing method.
