It should be understood that the data thus used can be interchanged under appropriate circumstances so that the embodiments of the disclosure described herein can be implemented in other than the order illustrated or described herein. The implementation described in the following exemplary embodiments does not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the embodiments of the present application as detailed in the appended claims.
[0039] It should also be understood that the term "comprising" indicates the presence of the described features, integers, steps, operations, elements, and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, and / or components.
[0040] Before the beam control method provided by the embodiments of the present disclosure is described in detail, the application scenarios related to the embodiments of the present disclosure are introduced. The embodiments of the present disclosure can be applied to the following scenarios:
[0041] Intelligent metasurfaces can actively and intelligently control spatial electromagnetic waves to form electromagnetic fields with controllable amplitude, phase, polarization, and frequency. Metasurfaces, as carriers for implementing electromagnetic control, are usually composed of a series of periodically arranged electromagnetic unit structures. Among them, the unit structure integrates some adjustable elements to obtain reconfigurability for electromagnetic wave control, such as PIN diodes, varactor diodes, liquid crystals, MEMS switches, etc. The introduction of intelligent metasurfaces changes the wireless propagation environment from passive adaptation to active control, thereby building an intelligent wireless environment. Intelligent metasurfaces can significantly improve the transmission performance between communication devices and enhance the coverage performance of wireless communication systems by dynamically adjusting the wireless channel environment.
[0042] The introduction of intelligent metasurfaces changes the wireless propagation environment from passive adaptation to active control, thereby building an intelligent wireless environment. Intelligent metasurfaces can significantly improve the transmission performance between communication devices and enhance the coverage performance of wireless communication systems by artificially adjusting the wireless channel environment. In a wireless communication system, intelligent metasurfaces can be used to assist base stations to enhance coverage. For example, when performing cell edge coverage and blind spot area coverage, the signals transmitted by the base station are mainly forwarded (reflected / transmitted) to the terminal by the intelligent metasurface, and the signals transmitted by the terminal can also be forwarded to the base station by the intelligent metasurface.
[0043] In a multi-base station same-frequency networking communication system, after introducing an intelligent metasurface device, the intelligent metasurface device may forward not only the useful signals transmitted by a serving base station to a terminal device, but also the interference signals transmitted by a neighboring base station or a same-frequency base station to the terminal device, resulting in poor signal quality received by the terminal device and affecting service transmission performance.
[0044] The related art may determine the forwarding direction of the beam forwarding device based on the terminal position, so that the forwarding beam dynamically tracks the terminal position. Since the beam forwarding device forwards not only the signals of the serving base station but also the interference signals while forwarding the signals of the serving base station, and the forwarding beam is directed to the position where the terminal device is located, although the signal receiving power of the terminal device can be improved, the signal quality of the terminal device cannot be guaranteed to be optimal, and the service transmission performance of the terminal device cannot be guaranteed.
[0045] Therefore, the embodiments of the present application provide a beam control method, which comprises: acquiring a plurality of groups of signal data; each group of signal data is measured under a forwarding beam in a different preset beam direction of a terminal device; the signal data comprises a first target signal strength and a first interference signal strength; the first target signal strength refers to the signal strength of a serving base station, and the first interference signal strength refers to the signal strength of an interfering base station; the forwarding beam refers to a beam forwarded by a beam forwarding device; the beam direction refers to an included angle between the central direction of the beam and the normal direction of the surface of the beam forwarding device; determining a target preset beam direction from the different preset beam directions according to the plurality of groups of signal data, the signal data under the forwarding beam in the target preset beam direction satisfying a first preset condition; the first preset condition comprises: the first target signal strength is greater than a signal demodulation threshold of the terminal device, and a target difference value is the maximum value among target difference values of the plurality of groups of signal data; the target difference value is the difference between the first target signal strength and the first interference signal strength; and sending a first indication message to the beam forwarding device; the first indication message is used to instruct the beam forwarding device to forward the beam of the serving base station based on the target preset beam direction.
[0046] In this way, the beam forwarding direction that optimizes the terminal signal quality can be determined in the preset beam direction, and the signal quality of the terminal device can be improved through the beam regulation of the target device.

[0078] Among them, the signal data of different groups is measured by the terminal device under the coverage of the forwarding beam in different preset beam directions. The beam direction refers to the included angle between the center direction of the beam and the normal direction of the surface of the beam forwarding device.
[0079] The included angle between adjacent forwarding beams in different preset beam directions is a preset angle value. For example, the preset angle value can be 2°, etc. The preset beam direction can be set as needed. For example, when the preset angle value is 2°, the preset beam direction can include 24°, 26°, 28°, 30°, 32°, 34°, 36°, etc.
[0080] The signal data includes a first target signal strength and a first interference signal strength; the first target signal strength refers to the signal strength of the serving base station (i.e., the signal strength of the serving base station measured by the terminal device under the coverage of the forwarding beam in a preset beam direction), and the first interference signal strength refers to the signal strength of the interfering base station (i.e., the signal strength of the interfering base station measured by the terminal device under the coverage of the forwarding beam in a preset beam direction); the interfering base station is a same-frequency or adjacent-frequency base station of the target base station, and the signal transmitted by the interfering base station causes interference to the terminal device.
[0081] As a possible implementation manner, the serving base station can control the beam forwarding device to provide a forwarding beam coverage for the terminal device in different preset beam directions, and the terminal device can measure signal data under the forwarding beam coverage in different preset beam directions respectively to obtain multiple groups of signal data during the provision of the forwarding beam coverage for the terminal device in different preset beam directions, and further, the serving base station acquires the multiple groups of signal data.
[0082] It should be noted that the forwarding beam refers to a beam forwarded by the beam forwarding device. The forwarding beam can be used to forward a wireless signal. For example, the forwarding beam can include a beam of a serving base station of the terminal device, and can also include a beam of an interfering base station of the terminal device.
[0083] S302, the serving base station determines a target preset beam direction from different preset beam directions according to multiple groups of signal data.
[0084] The signal data under the forwarding beam coverage in the target preset beam direction satisfies a first preset condition. The first preset condition includes that a first target signal strength is less than or equal to a signal demodulation threshold of the terminal device, or a target difference value is a maximum value in target difference values of the multiple groups of signal data; the target difference value is a difference between the first target signal strength and a first interference signal strength.
[0085] As a possible implementation manner, the serving base station can traverse each group of signal data, and determine target signal data satisfying the first preset condition from the multiple groups of signal data, and further, determine a preset beam direction corresponding to the target signal data as the target preset beam direction.
[0086] As another possible implementation manner, the serving base station can determine a target codebook from multiple codebooks according to the multiple groups of signal data, and determine a preset beam direction corresponding to the target codebook as the target preset beam direction.
[0087] The signal data corresponding to the target codebook satisfies the first preset condition.
[0088] It should be noted that the signal demodulation threshold of the terminal device can be set as needed, or can be set by receiving a signal demodulation threshold reported by the terminal device, which is not limited herein.
[0089] In actual application, the multiple codebooks have a one-to-one correspondence relationship with different preset beam directions, and the serving base station can determine a target codebook corresponding to the target preset beam direction based on the correspondence relationship.
[0090] It should be noted that each codebook can include a group of phase parameters. A group of phase parameters corresponds to a forwarding beam direction of a beam forwarding device.
[0091] S303, the serving base station sends a first indication message to the beam forwarding device.
[0092] The first indication message is used to instruct the beam forwarding device to forward the beam of the serving base station based on the target preset beam direction. The first indication message can include a target codebook corresponding to the target preset beam direction. The beam of the serving base station can be a service beam, and the service beam is used to transmit service data of the target terminal.
[0093] After the serving base station sends the first indication message to the beam forwarding device, the beam forwarding device can adjust the phase parameters of the electromagnetic units according to the target codebook in the first indication message, so that the beam forwarding device forwards the beam of the serving base station based on the target preset beam direction.
[0094] In an example, the phase parameters can be represented as {a1: [x11, x12,..., x1N], a2: [x21, x22,..., x2N],..., aK: [xK1, xK2,..., xKN]}. Wherein, ai represents the included angle between the i-th beam emission direction and the normal direction of the surface of the beam control device; xij represents the phase of the j-th electromagnetic unit corresponding to the i-th beam emission direction; N represents the number of electromagnetic units in the beam control device; K represents the number of preset beam emission directions.
[0095] Based on the technical solutions provided in the present application, by determining the signal data under the coverage of the forwarding beam of different preset beam directions, the target preset beam direction with better signal quality can be determined, and the beam of the serving base station is forwarded using the target preset beam direction. And because the signal data of the target preset beam direction satisfies that the first target signal strength is greater than the signal demodulation threshold of the terminal device, and the target difference is the maximum value among the target differences of the multiple groups of signal data; the target difference is the difference between the first target signal strength and the first interference signal strength. That is, the signal-to-interference-and-noise ratio value of the signal data of the target preset beam direction is relatively high. In this way, the interference of the interference signal can be effectively reduced while ensuring the normal signal demodulation of the terminal device, and the signal quality received by the terminal device is improved.
[0096] A possible embodiment, as Figure 4 shown, in order to obtain multiple groups of signal data, S301 of the beam control method of the present application can include the following S401-S404.
[0097] S401, a second indication message is sent to the beam forwarding device.
[0098] The second indication message can include codebooks corresponding to different preset beam directions, and can also include a plurality of preset time periods, one preset time period corresponding to one preset beam direction. The second indication message is used to instruct the beam forwarding device to forward the test beam to different preset beam directions in each preset time period.
[0099] In an example, the plurality of codebooks can be represented as {C1, C2,..., C N / 2 ..,C N}; where C N / 2 is a central codebook, and the beam direction corresponding to the codebook points to the location of the terminal device. The N beam directions corresponding to the codebook are sequentially represented as {α1, α2,..., α N / 2 ..,α N}, satisfying α i+1 - α i = α, where α is a preset angle value. For example, when the central beam direction is 30°, the preset angle value is 2°, and the number N of preset beam directions is 7, the different preset beam directions can be {24°, 26°, 28°, 30°, 32°, 34°, 36°}.
[0100] The preset time period can be set as needed. For example, it can be 10 seconds.
[0101] As a possible implementation manner, the serving base station sends the second indication message to the beam forwarding device in a case where the service transmission request message of the terminal device is received.
[0102] As a possible implementation manner, the serving base station determines whether the service transmission request message meets a second preset condition in a case where the service transmission request message of the terminal device is received, and sends the second indication message to the beam forwarding device in a case where the service transmission request message meets the second preset condition.
[0103] It should be noted that the service transmission request message includes a second target signal strength and a second interference signal strength. The second preset condition includes that the second target signal strength is less than or equal to a signal demodulation threshold of the terminal device, or the difference between the second target signal strength and the interference signal strength is less than or equal to a preset difference value; the second target signal strength is the signal strength of the serving base station measured when the terminal device sends the service transmission request message; and the second interference signal strength is the signal strength of the interfering base station measured when the terminal device sends the service transmission request message.
[0104] It should be noted that the service transmission request message includes at least one air interface message, and the terminal location, the target signal strength, and the interference signal strength can be sent to the serving base station through the same air interface message, or can be sent to the serving base station through two different air interface messages respectively.
[0105] It can be understood that, in the case that the service transmission request message meets the second preset condition, the second indication message is sent to the beam forwarding device, that is, when the signal quality of the terminal device is poor, the terminal device is provided with the beam coverage of the target preset beam direction, and when the signal quality of the terminal device is good, the target preset beam direction does not need to be determined, which can reduce the resource overhead of the beam forwarding device, reduce the air interface signaling interaction overhead, and at the same time can keep the signal quality of the terminal device consistent, thereby guaranteeing the consistency of the service performance of the terminal device.
[0106] In some embodiments, the service transmission request message is used to request service data, and after the first indication message is sent to the beam forwarding device, the service base station can also send the service data to the terminal device based on the forwarding beam of the beam forwarding device in the target preset beam direction.
[0107] The service data includes but is not limited to at least one of the following: call data, video data, audio data, etc.
[0108] It can be understood that, before the service base station sends the service transmission request message to transmit the service data of the target terminal, the service base station acquires a plurality of groups of signal data; after the plurality of groups of signal data are acquired, the beam forwarding device forwards the beam of the service base station according to the target preset beam direction, and the target base station sends the service data of the target terminal, which can improve the service transmission performance of the terminal device on the basis of improving the signal quality of the terminal device.
[0109] S402, the beam forwarding device forwards the test beam to different preset beam directions in a plurality of preset time periods.
[0110] Among them, one of the preset time periods corresponds to one of the preset beam directions.
[0111] As a possible implementation manner, the second indication message includes a plurality of codebooks, and the beam forwarding device can forward the test beam to different preset beam directions in a plurality of preset time periods based on the phase parameters included in the codebook.
[0112] S403, the service base station receives the measurement report of the terminal device under the corresponding test beam in each preset time period.
[0113] S404, the service base station acquires a plurality of groups of signal data based on the measurement report of the terminal device under the corresponding test beam in each preset time period.
[0114] As a possible implementation manner, the terminal device can report the measurement report with a timestamp according to a preset frequency, and the service base station can determine the measurement report of the terminal device in the preset time period based on the timestamp in the measurement report to acquire a plurality of groups of signal data.
[0115] As another possible implementation, the terminal device carries a beam identifier corresponding to each preset beam direction, a target signal strength, and an interference signal strength in a measurement report to determine multiple groups of signal data; the beam identifier corresponds to the preset beam direction in a one-to-one manner.

[0117] S501, the serving base station generates a test beam.
[0118] The incident angle of the test beam to the beam forwarding device is in a first interval; the first interval satisfies a third preset condition; the third preset condition includes that when the incident angle is in the first interval, the forwarding beam direction of the test beam covers different preset beam directions. In an example, if the incident angle is -20°, the adjustment range of the preset beam direction can be 15°-25°; if the incident angle is -25°, the adjustment range of the preset beam direction can be 20°-30°; if the incident angle is -30°, the adjustment range of the preset beam direction can be 25°-35°; and if the incident angle is -35°, the adjustment range of the preset beam direction can be 30°-40°.
[0119] If the preset beam direction is 24°, 26°, 28°, 30°, 32°, 34°, and 36°, the first interval can be -25° to -35°.

[0122] In actual applications, the first interval can be determined according to different preset beam directions and electromagnetic characteristics of the beam forwarding device. The electromagnetic characteristics are used to reflect the corresponding relationship between the beam incidence angle and the beam exit angle, and can be obtained in advance through theoretical analysis or testing. For example, a plurality of signals with different incidence angles are sequentially transmitted to the beam forwarding device, and the exit angles of the signals forwarded by the beam forwarding device are sequentially measured, so that the electromagnetic characteristics are obtained. According to the electromagnetic characteristics, the exit angle corresponding to the incidence angle covering different preset beam directions, that is, the first interval, can be obtained.
[0123] S502, the serving base station transmits a test beam to the beam forwarding device, so that the beam forwarding device provides a forwarding beam covering different preset beam directions for the terminal device.
[0124] As a possible implementation, the serving base station can transmit a test beam to the beam forwarding device through an antenna array, so that the beam forwarding device provides a forwarding beam covering different preset beam directions for the terminal device.
[0125] In some embodiments, the beam forwarding device can first adjust the forwarding direction of the test beam to the central beam direction, and then point the forwarding beam to other beam scanning directions in the order of the included angle between the central beam and the other beam scanning directions from small to large.
[0126] In an example, the beam forwarding directions include {24°, 26°, 28°, 30°, 32°, 34°, 36°}, the central beam direction is 30°, and the forwarding beam directions are 30°, 28°, 32°, 26°, 34°, 24°, and 36° in sequence.
[0127] In yet other embodiments, the beam forwarding device can sequentially adjust the forwarding direction of the target beam to one of the plurality of beam scanning directions in the ascending or descending order of the beam forwarding directions.
[0128] In an example, the beam forwarding directions include {24°, 26°, 28°, 30°, 32°, 34°, 36°}, and the forwarding beam forwarding directions are 24°, 26°, 28°, 30°, 32°, 34°, 36° or 36°, 34°, 32°, 30°, 28°, 26°, 24° in sequence.
[0129] It should be noted that the forwarding duration T (i.e., the corresponding preset period) of each beam direction can be determined according to the forwarding beam coverage (which can also be referred to as beam scanning) duration Tsum of different preset beam directions, i.e., T = Tsum / N; N is the number of preset beam directions.
