Description

A beam alignment method, information transmission method and related equipment

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on November 23, 2020, with application number 202011320759.X and application name “A beam alignment method, information transmission method and related equipment”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of communications, and in particular to a beam alignment method, an information transmission method, and related equipment. Background Art

[0003] Due to the high path loss in millimeter-wave communications, narrow-beam antennas are typically used to increase directional gain and compensate for losses along the propagation path. When the transmit and receive beams of narrow-beam antennas are aligned, the system achieves the highest antenna gain and optimal transmission performance. Furthermore, because terminal devices are mobile, beam scanning can be performed periodically while transmitting service data. The optimal beam is selected and fed back at the receiver, enabling transmit beam tracking. After the transmit beam is adjusted to its optimal state, the receive beam is then traversed again to obtain the optimal receive beam, achieving optimal performance across the entire transmit and receive link.

[0004] Currently, in millimeter-wave Wireless Fidelity (WIFI) beam alignment, the access point (AP) device periodically sends downlink scan frames. The different time slots of the scan frame are composed of signal segments pointing to different beams, which enables omnidirectional beam scanning. The station (STA) is a terminal device connected to the millimeter-wave WIFI. The STA obtains the transmission signals in different directions by receiving signal frames in different time periods. The STA then feeds back the received signal-to-noise ratio in different directions to the AP device to obtain the rough direction of the downlink transmission. After the coarse alignment is completed, a narrower beam scan is performed on the coarse alignment direction to determine the precise downlink transmission direction. Finally, the STA searches for the uplink transmission direction according to the same scanning mechanism as the downlink, thus completing the transceiver beam alignment.

[0005] However, continuous tracking requires a large number of time slots for scanning and alignment, which reduces the maximum bandwidth. When tracking is slow, beam misalignment may occur. Secondly, in scenarios with multiple access point devices, the access point device to be switched needs to be re-initialized and searched, resulting in service interruption, thereby reducing the accuracy and efficiency of beam alignment.

[0006] Summary of the Invention

[0007] The embodiments of the present application provide a beam alignment method, an information transmission method, and related equipment for improving the accuracy and efficiency of beam alignment.

[0008] In a first aspect, the present application provides a beam alignment method. This method can be executed by an access point device, or by a chip configured in the access point device, though this application is not limited thereto. The method includes: the access point device receiving a first message, then determining, based on the first message, first beam information directed toward a target terminal device, and then, based on the first beam information, aligning the antenna beam of the access point device toward the target terminal device.

[0009] In this embodiment, the first beam information directed toward the target terminal device is determined through the first message, eliminating the need to spend a large number of time slots for scanning and alignment. This ensures maximum bandwidth and ensures accurate beam information directed toward the target terminal device even during slow tracking, thereby improving beam alignment accuracy. Furthermore, in scenarios with multiple access points, switching access points eliminates the need for re-initialization search, and the obtained first beam information is directed toward the target terminal device, thus preventing any impact on the target terminal device's services. This improves beam alignment efficiency.

[0010] In an optional embodiment of the present application, the first message includes the location information of the terminal device, so the access point device can determine the first beam information based on the location information of the terminal device, the location information of the access point device, and the reference beam direction information of the antenna of the access point device.

[0011] In this implementation, the access point device can determine the first beam information through its own calculations using the location information of the terminal device included in the first message, thereby improving the feasibility of this solution.

[0012] In an optional embodiment of the present application, the reference beam direction information of the antenna of the access point device includes any one of normal direction information of the antenna of the access point device, or direction information perpendicular to the normal of the antenna of the access point device, or direction information at a preset angle to the normal of the antenna of the access point device.

[0013] In this embodiment, the access point device can flexibly determine the required reference beam direction information according to actual conditions through the reference beam direction information of the antennas of different access point devices, thereby improving the flexibility of determining the first beam information and thus improving the flexibility of this solution.

[0014] In an optional implementation manner of the present application, the first message includes first beam information.

[0015] In this implementation, the access point device directly determines the first beam information through the first message including the first beam information without performing any calculation, thereby improving the efficiency of determining the beam information.

[0016] In an optional implementation manner of the present application, the access point device may further send a second message to the target terminal device, so that the target terminal device can determine the second beam information pointing to the access point device according to the second message.

[0017] In this embodiment, the access point device sends a second message to the target terminal device, so that the target terminal device determines the second beam information pointing to the access point device according to the second message, thereby completing the mutual beam alignment between the target terminal device and the access point device, thereby improving the feasibility of beam alignment of this solution.

[0018] In an optional embodiment of the present application, the first message includes the location information of the terminal device and the reference beam direction information of the terminal device's antenna. Therefore, the access point device can determine the second beam information based on the location information of the access point device, the location information of the terminal device, and the reference beam direction information of the terminal device's antenna. The second message thus includes the determined second beam information.

[0019] In this embodiment, the access point device obtains the second beam information of the target terminal device pointing to the access point device through calculation, and carries the second beam information in the second message so that the target terminal device can directly determine the second beam information, thereby improving the efficiency of determining the beam information.

[0020] In an optional embodiment of the present application, the reference beam direction information of the antenna of the terminal device includes the normal direction information of the antenna of the terminal device, or the normal direction information perpendicular to the normal direction of the antenna of the terminal device, or any one of the direction information at a preset angle to the normal of the antenna of the terminal device.

[0021] In this embodiment, the access point device can flexibly determine the required reference beam direction information according to actual conditions through the reference beam direction information of the antennas of different terminal devices, thereby improving the flexibility of determining the second beam information and thus improving the flexibility of this solution.

[0022] In an optional implementation manner of the present application, the second message includes location information of the access point device.

[0023] In this embodiment, the access point device sends a second message including the location information of the access point device to the target terminal device, so that the target terminal device can determine the second beam information according to the location information, thereby improving the feasibility of this solution.

[0024] In a second aspect, the present application provides a beam alignment method. This method can be executed by a terminal device, or by a chip configured in the terminal device, and this application is not limited thereto. The method includes: the terminal device receiving a second message, then determining second beam information directed toward a target access point device based on the second message, and then aligning the terminal device's antenna beam toward the target access point device based on the second beam information.

[0025] In this embodiment, the second beam information directed toward the target access point is determined through the second message. Even when tracking is slow, the beam information directed toward the target access point is accurate, thereby improving beam alignment accuracy. Furthermore, in scenarios with multiple access points, when a terminal device needs to switch access points while moving, the second beam information obtained by the terminal device is directed toward the target access point providing the service. Therefore, the terminal device can perform normal service, thereby improving beam alignment efficiency.

[0026] In an optional embodiment of the present application, the second message includes the location information of the target access point device, so the terminal device can determine the second beam information based on the location information of the target access point device, the location information of the terminal device, and the reference beam direction information of the antenna of the terminal device.

[0027] In this embodiment, the terminal device can determine the second beam information through its own calculation using the location information of the access point device included in the second message, thereby improving the feasibility of this solution.

[0028] In an optional embodiment of the present application, the reference beam direction information of the antenna of the terminal device includes the normal direction information of the antenna of the terminal device, or the normal direction information perpendicular to the normal direction of the antenna of the terminal device, or any one of the direction information at a preset angle to the normal of the antenna of the terminal device.

[0029] In this embodiment, the terminal device can flexibly determine the second beam information according to actual conditions through the reference beam direction information of the antennas of different terminal devices, thereby improving the flexibility of this solution.

[0030] In an optional implementation of the present application, the second message includes second beam information.

[0031] In this implementation, the access point device directly determines the second beam information through the second message including the second beam information without performing any calculation, thereby improving the efficiency of determining the beam information.

[0032] In an optional implementation manner of the present application, the terminal device sends a first message to the target access point device, so that the target access point device determines first beam information pointing to the terminal device according to the first message.

[0033] In this embodiment, the terminal device sends a first message to the target access point device, so that the target access point device determines the first beam information pointing to the terminal device according to the first message, thereby completing the mutual beam alignment between the target access point device and the terminal device, thereby improving the feasibility of beam alignment of this solution.

[0034] In an optional embodiment of the present application, the second message includes the location information of the target access point device and the reference beam direction information of the antenna of the target access point device. Therefore, the terminal device can determine the first beam information based on the location information of the terminal device, the location information of the target access point device, and the reference beam direction information of the antenna of the target access point device, and the first message sent to the target access point device includes the first beam information.

[0035] In this embodiment, the terminal device obtains the first beam information of the target access point device pointing to the terminal device through calculation, and carries the first beam information in the first message so that the target access point device can directly determine the first beam information, thereby improving the efficiency of determining the beam information.

[0036] In an optional embodiment of the present application, the reference beam direction information of the antenna of the target access point device includes any one of normal direction information of the antenna of the target access point device, or direction information perpendicular to the normal of the antenna of the target access point device, or direction information forming a preset angle with the normal of the antenna of the target access point device.

[0037] In this embodiment, the terminal device can flexibly determine the required reference beam direction information according to actual conditions through the reference beam direction information of the antennas of different access point devices, thereby improving the flexibility of determining the first beam information and thus improving the flexibility of this solution.

[0038] In an optional implementation manner of the present application, the first message includes location information of the terminal device.

[0039] In this implementation, the terminal device sends a second message including the location information of the access point device to the target access point device, so that the target access point device can determine the first beam information according to the location information, thereby improving the feasibility of this solution.

[0040] In a third aspect, the present application provides a method for information transmission. The method can be executed by a location service device, or by a chip configured in the location service device. The location service device can be an access point device or an access point device, which is not limited in this application. The method includes: the location service device sends a first message to a target access point device, so that the target access point device determines first beam information pointing to a target terminal device based on the first message; secondly, the location service device also sends a second message to the target terminal device, so that the target terminal device determines second beam information pointing to the target access point device based on the second message.

[0041] In this embodiment, the location service device, through the first message and the second message, can enable the target access point device to determine the first beam information pointing to the target terminal device, and enable the target terminal device to determine the second beam information pointing to the target access point device. Therefore, when tracking is slow, the beam information determined by the target terminal device and the target access point device is accurate, thereby improving the accuracy of beam alignment. Secondly, in a scenario with multiple access point devices, there is no need to re-initialize the search when switching access point devices. The mutual beam alignment between the target access point device and the terminal device can be completed using the determined beam information. Therefore, it will not affect the service of the target terminal device switching between multiple access point devices, thereby improving the efficiency of beam alignment.

[0042] In an optional implementation manner of the present application, the first message includes location information of the target terminal device.

[0043] In this embodiment, since the first message includes the location information of the target terminal device, the target access point device can obtain the location information of the target terminal device through the first message, and thereby determine the first beam information based on the location information of the target terminal device, the location information of the target access point device, and the reference beam direction information of the antenna of the target access point device, thereby improving the feasibility of this solution.

[0045] In this embodiment, the location service device determines the first beam information based on the acquired location information of the target terminal device, the location information of the target access point device, and the reference beam direction information of the antenna of the target access point device, and carries the first beam information in the first message, so that the target access point device can directly determine the first beam information without performing any calculation, thereby improving the efficiency of determining the beam information.

[0047] In this embodiment, since there are multiple options for the reference beam direction information of the antenna of the target access point device, the access point device can flexibly determine the required reference beam direction information according to actual conditions, thereby improving the flexibility of determining the first beam information, thereby improving the flexibility of this solution.

[0048] In an optional implementation manner of the present application, the second message includes location information of the target access point device.

[0049] In this embodiment, since the second message includes the location information of the target access point device, the target terminal device can obtain the location information of the target access point device through the second message, and thus determine the second beam information based on the location information of the target access point device, the location information of the target terminal device, and the reference beam direction information of the antenna of the target terminal device, thereby improving the feasibility of this solution.

[0050] In an optional embodiment of the present application, the location service device can also obtain the location information of the target access point device, as well as the location information of the target terminal device and the reference beam direction information of the antenna of the target terminal device, and then determine the second beam information based on the location information of the target access point device, the location information of the target terminal device and the reference beam direction information of the antenna of the target terminal device, and then send a second message including the second beam information to the target terminal device.

[0137] The technical solution in this application will be described below with reference to the accompanying drawings.

[0138] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as millimeter wave Wi-Fi systems or long term evolution (LTE) systems. As communication systems continue to develop, the technical solutions of the present application can be applied to fifth generation (5G) systems or new radio (NR) systems, and can also be applied to future networks such as 6G systems and even future systems; or can also be used in device to device (D2D) systems, machine to machine (M2M) systems, and so on.

[0139] It should be understood that the access point device in the communication system can be any device with wireless transceiver functions or a chip that can be set in the device, including but not limited to: evolved Node B (eNB), Radio Network Controller (RNC), Node B (NB), Base Station Controller (BSC), Base Transceiver Station (BTS), Home base station (for example, Home evolved NodeB, or Home Node B, HNB), Baseband Unit (BBU), AP in WIFI system, wireless relay node, wireless backhaul node, transmission point (TP) or transmit and receive point (TRP), etc., and can also be a device used in 5G, 6G or even future systems, such as NR, gNB in ​​the system, or, transmission point (TRP or TP), one or a group of (including multiple antenna panels) antenna panels of a base station in a 5G system, or it can also be a network node constituting a gNB or transmission point, such as a baseband unit (BBU), or a distributed unit (distributed unit). unit (DU), or picocell, or femtocell, or vehicle to everything (V2X) or road side unit (RSU) in intelligent driving scenarios, etc.

[0140] In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include a radio unit (RU). The CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU implements the functions of the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer, while the DU implements the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical layer (PHY). Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling or PDCP layer signaling, can also be considered to be sent by the DU, or by both the DU and the RU. It is understood that an access point device can be a CU node, a DU node, or a device that includes both a CU node and a DU node. In addition, the CU may be classified as an access point device in the access network RAN, or may be classified as an access point device in the core network CN, which is not limited here.

[0142] In the embodiments disclosed in the present application, the location service device may be an access point device, may be installed in an access point device, or may be a device that can support the location service device to implement the function, etc., which is not limited herein.

[0143] It should also be understood that if applied to a millimeter wave WIFI system, the STA in the system is a terminal device connected to the millimeter wave WIFI, and the terminal device can also be called user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. The terminal device in the embodiment of the present application can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a wireless terminal in the aforementioned V2X vehicle network or an RSU of wireless terminal type, etc. The embodiment of the present application does not limit the application scenario.

[0144] In addition, in order to facilitate understanding of the embodiments of the present application, the following explanations are made.

[0145] First, for ease of description, in this application, when numbering, consecutive numbers may be used starting from 0. For example, the 0th symbol in a time slot may refer to the first symbol in that time slot. Of course, this is not a limitation in the specific implementation. For example, consecutive numbering may also start from 1. For example, the 1st symbol in a time slot may also refer to the first symbol in that time slot. Due to different starting values ​​for numbering, the same symbol will have different numbers in the time slot.

[0146] It should be understood that the above descriptions are all made for the purpose of describing the technical solutions provided by the embodiments of the present application, and are not intended to limit the scope of the present application.

[0147] Second, in the embodiments shown below, for a technical feature, the technical features in the technical feature are distinguished by "first", "second", "third", etc., and there is no order of precedence or size between the technical features described by the "first", "second", and "third".

[0148] Third, "at least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b and c can mean: a, or b, or c, or a and b, or a and c, or b and c, or a, b and c. Where a, b and c can be single or multiple, respectively.

[0149] Fourth, in the embodiments shown below, some scenarios are illustrated using the NR network scenario in a wireless communication network as an example.

Furthermore, combinations of these solutions may also be used.

[0151] Sixth, in the embodiments disclosed in this application, "of", "relevant" and "corresponding" can sometimes be used interchangeably. It should be pointed out that when the distinction between them is not emphasized, the meanings they intend to express are consistent.

[0152] Due to the large path loss in millimeter wave communication, narrow beam antennas are usually used to improve directional gain to compensate for the loss in the propagation path. Please refer to Figure 1, which is a schematic diagram of an embodiment of the alignment of the transceiver antenna beams in the embodiment of the present application. As shown in Figure 1, when the narrow beam antenna of the terminal device pointing to the access point device is aligned with the narrow beam antenna of the access point device pointing to the terminal device, the system will obtain the highest antenna gain and achieve optimal transmission performance. However, due to the movement of the terminal device, the antenna beam will be deflected, which will greatly reduce the signal transmission quality and affect the link transmission performance. To solve this problem, it is usually necessary to perform beam scanning regularly while transmitting business data, and to select and feedback the optimal beam on the receiver side to achieve tracking of the transmitting beam. The receiving beam also needs to be traversed again after the transmitting beam is adjusted to the optimal one to obtain the optimal receiving beam, so that the entire transceiver link can achieve the best performance. In addition, when this embodiment is applied to a millimeter wave communication scenario in a home network, please refer to FIG2 , which is a schematic diagram of an embodiment of a millimeter wave communication scenario applied to a home network in an embodiment of the present application. As shown in FIG2 , A1 indicates a terminal device, A2 to A5 indicate rooms, and access point device A can establish a connection with a terminal device in room A2, access point device B can establish a connection with terminal devices in rooms A3 and A4, and access point device C can establish a connection with a terminal device in room A5. Due to the characteristic that millimeter waves cannot penetrate walls, when a terminal device moves between rooms, for example, when the terminal device moves from the current room A2 to room A5, the link between access point device A in room A2 and the terminal device will be interrupted, while the connection between access point device C in room A5 and the terminal device has not yet been established. At this time, the access point device C and the terminal device will undergo a long registration process and a new beam alignment process, thereby affecting the service provided to the terminal device and reducing the service quality.

[0153] Currently, in millimeter-wave Wi-Fi beam alignment, the AP periodically transmits downlink scanning frames. Different time slots in these scanning frames are composed of signal segments from different beam directions, enabling omnidirectional beam scanning. A STA (a terminal device connected to the millimeter-wave Wi-Fi) receives signal frames from different time periods to obtain transmission signals from different directions. The STA then feeds the received signal-to-noise ratio (SNR) at each direction back to the AP, thereby obtaining a rough downlink transmission direction. After coarse alignment is complete, a narrower beam scan is performed in the coarse alignment direction to determine the precise downlink transmission direction. Finally, the STA searches for the uplink transmission direction using the same scanning mechanism as for the downlink, completing the transmit and receive beam alignment. However, continuous tracking requires a significant number of time slots for scanning and alignment, reducing the maximum bandwidth. Slow tracking can lead to beam misalignment. Furthermore, in scenarios with multiple access points, the access point to be switched needs to re-initialize the search, resulting in service interruption and reduced beam alignment accuracy and efficiency.

[0154] In order to solve the above problems, the embodiment of the present application provides a beam alignment method and an information transmission method for improving the accuracy of beam alignment and improving the efficiency of beam alignment. Secondly, in order to better understand the beam alignment method, information transmission method and related equipment disclosed in the embodiment of the present application, first, the system architecture of the communication system used in the embodiment of the present application is described. The present application can be used for a communication system consisting of a terminal device, a location service device and multiple access point devices, and can also be used for a communication system consisting of multiple terminal devices, multiple location service devices and multiple access point devices. Based on this, Figure 3 is a schematic diagram of a system architecture of the communication system in the embodiment of the present application. As shown in Figure 3, a terminal device, a location service device and multiple access point devices form a communication system. In this communication system, the location service device and the terminal device can send a first message to any one of the access point devices 1 to 3, and the location service device and the access point devices 1 to 3 can send a second message to the terminal device. In addition, a terminal device and multiple access point devices can also form a communication system. Therefore, in this communication system, the terminal device can send a first message to any one of access point devices 1 to 3, and access point devices 1 to 3 can send a second message to the terminal device.

[0155] Based on this, since the first message received by the access point device can be sent by the terminal device or by the location service device, and the second message received by the terminal device can be sent by the access point device or by the location service device, the first message and the second message are sent from different devices and apparatuses respectively, and the beam alignment method used in the embodiment of the present application is described in detail below.

[0156] 1. The target access point device receives a first message sent by the location service device, and the target terminal device receives a second message sent by the location service device.

[0157] Specifically, in this embodiment, the first message may include the location information of the target terminal device, or the first message may also include the first beam information. Secondly, the second message may include the location information of the target access point device, or the second message may also include the second beam information.

[0158] Therefore, this embodiment further introduces and describes the situation where the first message and the second message include different information.

[0159] (1) The first message includes first beam information, and the second message includes second beam information.

[0160] Please refer to FIG4 , which is a schematic diagram of an embodiment of a beam alignment method in an embodiment of the present application. As shown in FIG4 , the beam alignment method includes the following steps.

[0161] S101. A location service apparatus obtains location information of a target terminal device and reference beam direction information of an antenna of the target terminal device.

[0162] In this embodiment, for scenarios where there are multiple access point devices in a home network, when a target terminal device needs to connect to an access point device, the target terminal device can use a low-frequency band (e.g., 2.4GHz) or wide-beam broadcast to send online information, and send the target terminal device's location information to a location service device via wide-beam broadcast, so that the location service device can obtain the target terminal device's location information. Secondly, the location service device can also determine the target terminal device's location information through millimeter wave positioning, or determine the target terminal device's location information through auxiliary methods, including but not limited to infrared, wireless LAN (Wireless-Fidelity, WIFI), and sound.

[0163] It is understandable that the location service device can also receive the reference beam direction information of the antenna of the target terminal device sent by the target terminal device in a similar manner through a wide beam broadcast method, or determine the reference beam direction information of the antenna of the target terminal device through millimeter wave positioning, or determine the reference beam direction information of the antenna through an auxiliary method. Specifically, the reference beam direction information of the antenna of the target terminal device includes any one of the normal direction information of the antenna of the target terminal device, or the normal direction information perpendicular to the normal direction of the antenna of the target terminal device, or the direction information at a preset angle to the normal of the antenna of the target terminal device.

[0164] In this embodiment, the specific manner in which the location service apparatus obtains the location information of the target terminal device and the reference beam direction information of the antenna of the target terminal device is not limited.

[0165] S102: The location service apparatus obtains location information of a target access point device and reference beam direction information of an antenna of the target access point device.

[0166] In this embodiment, in a scenario where there are multiple access point devices in a home network, since the location service has been configured through manual entry when deploying the millimeter wave communication network, the location service device can store the location information of each access point device and can also store the reference beam direction information of the antenna of each access point device.

[0167] Furthermore, the location service device needs to obtain real-time information of each access point device, which includes traffic information of each access point device or signal strength information of each access point device, and then determine the target access point device that provides administrative services for the target terminal device from multiple access point devices based on the location information and real-time information of the target terminal device obtained in step S101, thereby obtaining the location information of the target access point device and the reference beam direction information of the antenna of the target access point device from the relevant information of the multiple access point devices manually entered.

[0168] Specifically, the reference beam direction information of the antenna of the target access point device includes any one of normal direction information of the antenna of the target access point device, or direction information perpendicular to the normal direction of the antenna of the target access point device, or direction information forming a preset angle with the normal direction of the antenna of the target access point device.

[0169] It can be understood that in a scenario where there are multiple access point devices in a home network, in an embodiment of the present application, the location service device will convert the location information of the target terminal device and the location information of the target access point device into a home network coordinate system, thereby placing the target terminal device and the target access point device in the same plane coordinate system for ease of calculation. This should not be understood as a limitation of the present application.

[0170] S103: The location service apparatus determines first beam information according to the location information of the target terminal device, the location information of the target access point device, and the reference beam direction information of the antenna of the target access point device.

[0171] In this embodiment, after the location service device obtains relevant information about the target terminal device and the target access point device through steps S101 and S102, it can determine first beam information based on the location information of the target terminal device, the location information of the target access point device, and the reference beam direction information of the antenna of the target access point device. Specifically, the first beam information includes direction information and angle information of the antenna beam of the target access point device pointing toward the target terminal device.

[0172] S104: The location service apparatus determines second beam information according to the location information of the target access point device, the location information of the target terminal device, and the reference beam direction information of the antenna of the target terminal device.

[0173] In this embodiment, after the location service device obtains relevant information of the target terminal device and the target access point device through steps S101 and S102, it can determine the second beam information based on the location information of the target access point device, the location information of the target terminal device, and the reference beam direction information of the antenna of the target terminal device. Specifically, the second beam information includes direction information and angle information of the antenna beam of the target terminal device pointing to the target access point device.

[0174] It is understandable that, in this embodiment, there is no necessary order between step S103 and step S104. Step S103 may be executed first, or step S104 may be executed first, or step S103 and step S104 may be executed simultaneously. The specific order is not limited here.

[0175] S105: The location service apparatus sends a first message to the target access point device.

[0176] In this embodiment, the location service apparatus sends a first message to the target access point device, where the first message includes the first beam information determined in step S103.

[0180] S107. The target access point device determines first beam information pointing to the target terminal device according to the first message.

[0181] In this embodiment, the target access point device directly determines the first beam information pointing to the target terminal device according to the first beam information included in the first message.

[0182] S108. The target terminal device determines second beam information pointing to the target access point device according to the second message.

[0183] In this embodiment, the target terminal device directly determines the second beam information pointing to the target access point device according to the second beam information included in the second message.

[0185] S109: The target access point device aligns the antenna beam of the target access point device with the target terminal device according to the first beam information.

[0186] In this embodiment, the target access point device aligns the antenna beam of the target access point device toward the target terminal device according to the direction information and angle information of the antenna beam of the target access point device pointing toward the target terminal device included in the first beam information.

[0187] For ease of understanding, the reference beam direction information of the antenna of the target access point device is taken as the normal direction information of the antenna of the target access point device, and the direction information and angle information included in the first beam information indicate that the normal direction of the antenna of the target access point device is counterclockwise, and the antenna beam with an angle of 100° is aligned with the target terminal device as an example. Please refer to Figure 5, which is a schematic diagram of an embodiment of aligning the antenna beam of the access point device with the terminal device in an embodiment of the present application. As shown in Figure 5, B1 indicates the antenna beam of the target access point device. The antenna beam B1 is an antenna beam with a normal direction of the antenna of the target access point device determined according to the first beam information, and the angle is 100°.

[0189] In this embodiment, the target access point device aligns the antenna beam of the target access point device toward the target terminal device according to the direction information and angle information of the antenna beam of the target access point device pointing toward the target terminal device included in the first beam information.

[0190] For ease of understanding, the reference beam direction information of the antenna of the target terminal device is taken as the normal direction information of the antenna of the target terminal device, and the direction information and angle information included in the second beam information indicate that the normal direction of the antenna of the target terminal device is counterclockwise, and the antenna beam with an angle of 100° is aligned with the target access point device as an example. Please refer to Figure 6, which is a schematic diagram of an embodiment of aligning the antenna beam of the terminal device with the access point device in an embodiment of the present application.

The antenna beam C1 is the antenna beam of the target terminal device determined according to the second beam information, and the normal direction of the antenna of the target terminal device is counterclockwise, and the angle is 100°. Therefore, the target terminal device aligns the antenna beam C1 with the target access point device.

[0191] It can be understood that, in this embodiment, there is no necessary order between step S109 and step S1010. Step S109 can be executed first, or step S1010 can be executed first, or step S109 and step S1010 can be executed at the same time. The specific order is not limited here.
