[0002] With the widespread adoption of smart terminals (such as mobile phones, tablets, and smart screens) and their associated wireless peripherals (such as wireless headphones, wireless speakers, and smart pens), the density of indoor wireless communication has increased dramatically.

[0003] In related technologies, a beamforming scheme based on a planar massive MIMO antenna array is employed. This scheme typically involves multiple antenna elements arranged in a specific pattern (such as a rectangular grid) on a two-dimensional plane. The system controls the phase and amplitude of each antenna element through a baseband processing chip, causing the signals emitted by multiple antenna elements to be superimposed in phase in a specific direction in space, forming a high-gain narrow beam. Through algorithmic calculations, this beam can be scanned in a one-dimensional or two-dimensional plane to align with the target device.

[0004] However, this method typically limits the beam scanning range to a certain angle on the front of the array.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] Exemplary Implementation Environment The antenna control method according to embodiments of this application can be executed by electronic devices such as terminal devices or servers. The terminal device can be user equipment (UE), mobile device, user terminal, terminal, cellular phone, cordless phone, personal digital assistant (PDA), handheld device, computing device, vehicle-mounted device, wearable device, etc. The server can be an independent physical server, a server cluster composed of multiple physical servers, or a cloud server capable of cloud computing. This method can be implemented by a processor calling computer-readable program instructions stored in memory. This application uses the example of the antenna control method being executed by a server for explanation, but does not limit it.

[0029] Exemplary device Please see Figure 1In one exemplary embodiment, an antenna is provided, including: a wireless communication unit 1, a control unit 2, and a plurality of antenna units 3; Each antenna element radiates in a directional manner according to its own preset radiation direction. All the antenna elements are combined to form a sphere, and the radiation range of all the antenna elements can cover all directions of space. The control unit is used to acquire communication quality parameters between each antenna unit and the terminal when the antenna adjustment trigger condition is met; determine the target antenna unit with the best communication quality among multiple antenna units based on the communication quality parameters; control the wireless communication unit to communicate with the terminal through the target antenna unit, and the antenna adjustment trigger condition is used to indicate that the antenna unit communicating in the antenna needs to be adjusted.

[0030] In some embodiments, multiple antenna elements are configured, and all the antenna elements are combined to form a spherical shape. The radiation range of all the antenna elements can cover all directions in space, so that the terminal can be radiated by antenna elements at any position. Even if the terminal moves, the communication quality parameters of each antenna element can be obtained to select the target antenna element with the best communication quality to communicate with the terminal, thereby improving the communication effect.

[0031] Among them, the communication quality parameter can be, but is not limited to, the Signal Strength Indicator (RSSI) value. The RSSI value is a key indicator in the field of wireless communication used to measure the power of the radio frequency signal captured by the antenna at the receiving end. It reflects the degree of signal propagation loss between the transmitting end and the receiving end and is one of the core bases for judging the quality of the wireless link, the distance, and whether it is necessary to switch channels / base stations.

[0032] The wireless communication unit can be, but is not limited to, a WIFI / BT (Bluetooth) transceiver, through which signals are transmitted and received.

[0033] The control unit may be, but is not limited to, a logic control unit, which includes an MCU processor that provides processing capabilities for subsequent scanning programs and control of switching units.

[0034] Antenna elements can be, but are not limited to, horn antennas. An antenna element can be in the form of a sphere, with its maximum radiation direction being either the outward normal or the tangent direction pointing towards the sphere. Each antenna element radiates directionally in its radiation direction and within a certain angular range. By setting multiple antenna elements, the radiation ranges of each antenna element overlap, thereby enabling the antenna's radiation range to cover all directions in space.

[0035] Among them, the horn antenna is a widely used microwave antenna. Its advantages include simple structure, wide bandwidth, large power capacity, and convenient adjustment and use. The basic form of the horn antenna is formed by gradually expanding the opening of a rectangular or circular waveguide. Because the opening of the waveguide is gradually expanded, the matching between the waveguide and free space is improved, resulting in a small reflection coefficient in the waveguide. That is, most of the energy transmitted in the waveguide is radiated by the horn, and the reflected energy is very small.

[0036] In an optional embodiment, the antenna further includes: an antenna carrier and a switching unit; The antenna carrier is spherical, and the plurality of antenna elements are disposed on the antenna carrier; The switching unit is connected to the wireless communication unit; The control unit controls the wireless communication unit to communicate with the terminal through the target antenna unit, including: The control unit controls the switching unit to connect with the target antenna unit, so that the wireless communication unit can communicate with the terminal through the target antenna unit.

[0037] In some embodiments, the antenna carrier can be a spherical or near-spherical polyhedral structure. Mounting slots for installing each antenna element are provided on the antenna carrier, and the antenna elements are installed in the mounting slots to obtain... Figure 2 The antenna shown.

[0038] The antenna elements can be uniformly distributed on the antenna carrier to minimize mutual coupling between the elements and ensure consistent electrical performance across all elements. This results in a spherical antenna structure that provides comprehensive coverage in all spatial directions.

[0039] The switching unit can be, but is not limited to, a multi-channel radio frequency switching network, which can selectively connect only one or a group of specific antenna units to the transceiver at any given time.

[0040] It is understandable that the switching unit can also be a high-speed radio frequency switching matrix, which can be integrated into the above-mentioned logic control unit. The logic control unit generates control signals according to the preset scanning strategy to quickly switch the current switching matrix to the target antenna unit.

[0041] See Figure 3 Taking a switch matrix as the switching unit, an MCU as the control unit, and a WIFI / BT as the wireless communication unit as an example, the MCU sends control signals (CTL) to the switch matrix, and the switch matrix selects the corresponding antenna unit for connection. Figure 3 The circles on the edge of the switch matrix represent the connection terminals for connecting antenna elements.

[0042] In an optional embodiment, when there are multiple target antenna elements, the control unit is further configured to: Based on the communication quality parameters, a preset number of candidate antenna elements are determined to achieve the best communication quality. Obtain the first spatial coordinates and radiation direction of the candidate antenna element; The second spatial coordinates of the terminal are determined based on the first spatial coordinates of the candidate antenna element, the radiation direction, and the communication quality parameters.

[0043] In some embodiments, since each antenna element is configured on the antenna, and the spatial position of each antenna element on the antenna can be determined after the antenna is installed, the spatial position of the terminal can be determined by the relevant information of multiple antenna elements connected to the terminal, thereby enabling precise positioning of the terminal.

[0044] The control unit determines a preset number (e.g., the first 3) of candidate antenna units with the best communication quality based on communication quality parameters. Since the spatial position of the antenna units is fixed, after determining the candidate antenna units, the first spatial coordinates, radiation direction and communication quality parameters of each candidate antenna unit can be obtained. The second spatial coordinates of the terminal are calculated using triangulation or fingerprint positioning algorithms.

[0045] Specifically, the communication delay between each candidate antenna element and the terminal is determined, and the communication distance between the candidate antenna element and the terminal is determined using the communication delay and communication quality parameters. Based on the communication distance between each candidate antenna element and the terminal and the first spatial coordinates of the candidate antenna elements, the second spatial coordinates of the terminal are solved by using a set solution method with the first spatial coordinates as the origin and the communication distance as the radius.

[0046] For example, taking a candidate antenna element count of three as an example, we can substitute the following formula: (x-x1) 2 +(y-y1) 2 =d1 2 ; (x-x2) 2 +(y-y2) 2 =d2 2 ; (x-x3) 2 +(y-y3) 2 =d3 2 ; Where x1 and y1 represent the abscissa and ordinate of the first candidate antenna element in the first spatial coordinate system, respectively; d1 represents the communication distance between the first candidate antenna element and the terminal; x2 and y2 represent the abscissa and ordinate of the second candidate antenna element in the first spatial coordinate system, respectively; d2 represents the communication distance between the second candidate antenna element and the terminal; x3 and y3 represent the abscissa and ordinate of the third candidate antenna element in the first spatial coordinate system, respectively; d3 represents the communication distance between the third candidate antenna element and the terminal; and x and y represent the abscissa and ordinate of the terminal in the second spatial coordinate system, respectively.

[0047] The antenna in this application includes a logic control unit, a WiFi transceiver, and an antenna matrix. The antenna matrix includes multiple antenna elements. The logic control unit includes a control unit (MCU) and a switch matrix. This logic control unit can be implemented in the following manner (see [reference]). Figure 4 The MCU has a preset scanning strategy. The program controls a switch matrix to connect each antenna element sequentially. The Wi-Fi transceiver reads the RSSI and sends the value back to the MCU. The MCU establishes a real-time RSSI switch matrix mapping table, selects the target antenna element based on the RSSI value in the table, and then controls the switch matrix to connect to that target antenna element. This enables omnidirectional, seamless signal tracking and enhancement of mobile devices in three-dimensional space, avoiding signal attenuation in specific directions while reducing the complexity of beam management algorithms.

[0048] Exemplary methods In one exemplary embodiment, a method for controlling an antenna is provided. The antenna includes a wireless communication unit, a control unit, and multiple antenna elements. Each antenna element radiates in a directional manner according to its preset radiation direction. All antenna elements are combined to form a spherical shape, and the radiation range of all antenna elements can cover all directions in space. The antenna control method is applied to the control unit. Specifically, the specific structure and embodiments of this antenna can be found in the aforementioned related embodiments, and will not be repeated here.

[0049] Please see Figure 5 The antenna control method provided in this application includes: Step 501: Under the condition that the antenna adjustment triggering condition is met, obtain the communication quality parameters of each antenna element in the antenna communicating with the terminal. The antenna adjustment triggering condition is used to indicate that the antenna element communicating in the antenna needs to be adjusted.

[0050] In some embodiments, when the antenna meets the antenna adjustment triggering conditions, it indicates that the antenna element communicating in the antenna needs to be adjusted. This can occur when the terminal requests to connect to the antenna, or after the terminal has connected to the antenna.

[0051] After antenna initialization, the wireless communication unit is operational. It periodically broadcasts beacon frames as an Access Point (AP) or scans the environment as a Site Station (STA) to achieve the core interaction mechanism for device discovery and network access. These two mechanisms work together to establish a link. After antenna initialization, a specific antenna element or a group of antenna elements can be used for omnidirectional listening. When a terminal (such as a smartphone) initiates a connection request or is already connected, the antenna array scanning process is triggered. During the scanning process, the communication quality parameters of each antenna element are acquired.

[0052] In an optional embodiment, the antenna further includes a switching unit connected to the wireless communication unit. The step of obtaining the communication quality parameters of each antenna element in the antenna communicating with the terminal, i.e., the scanning process described above, includes: The control switch unit is connected to each antenna unit in sequence; Each time the antenna unit is connected, the wireless communication unit in the antenna communicates with the terminal based on the connected antenna unit and obtains the communication quality parameters of the communication between the antenna unit and the terminal during the communication.

[0053] In some embodiments, the control unit can sequentially switch and activate each antenna element in a predetermined order (e.g., according to the antenna element numbers from 1 to n). Each time an antenna element is activated, the transceiver conducts a brief communication with the terminal through that antenna element (e.g., sending a probe request / response) and records the communication quality parameters of the received signal corresponding to that antenna element at that moment.

[0054] After obtaining the communication quality parameters of each antenna element, the control unit can establish a mapping table between the antenna element number and the communication quality parameters, and store the mapping table.

[0055] The communication quality parameter may be, but is not limited to, the Signal Strength Indication (RSSI) value.

[0056] The antenna control triggering conditions include: the time when the connection request of the terminal is detected, a preset time interval from the time when the communication quality parameters of each antenna element in the antenna were last obtained, or the communication quality parameters of the target antenna element are less than a preset value.

[0057] When a terminal sends a connection request to an antenna, it is impossible to determine the communication quality parameters of each antenna element in the antenna since no connection has been established with the antenna before. Therefore, by obtaining the communication quality parameters between each antenna element and the terminal, a better communication channel can be provided to the terminal based on these communication quality parameters.

[0058] Because the communication quality parameters (such as RSSI) of antenna elements fluctuate dynamically with environmental changes (such as personnel movement, increase or decrease of obstacles, and switching of interference sources), historical communication quality parameters obtained at long intervals become invalid and cannot reflect the current true channel state. Therefore, the communication quality parameters of each antenna element and the terminal can be reacquired at regular intervals to improve communication efficiency. By periodically re-executing the scanning process, the target antenna element with the best communication quality is updated, thereby achieving dynamic and real-time signal tracking.

[0059] If the communication quality parameters of the target antenna element are substandard, it means that the current link may have problems such as weak signal, strong interference, and low transmission efficiency. Continued use may lead to connection failure, high packet loss rate, and reduced data rate. Therefore, if the communication quality of the target antenna element is lower than the preset value, the communication quality parameters of each antenna element and the terminal can be reacquired to improve communication efficiency.

[0060] Step 502: Determine the target antenna element with the best communication quality among multiple antenna elements based on the communication quality parameters.

[0061] In some embodiments, after completing a scan, the antenna element with the highest communication quality parameter is selected from the communication quality parameters recorded in the obtained mapping table, and it is used as the target antenna element. The direction pointed to by the antenna element is determined to be closest to the current location of the terminal.

[0062] Understandably, to improve communication quality, a predetermined number of antenna elements with the best communication quality can be selected as target antenna elements. Multiple target antenna elements simultaneously provide communication channels for the terminal, thereby improving communication quality.

[0063] Step 503: Control the wireless communication unit to communicate with the terminal through the target antenna unit.

[0064] In some embodiments, the target antenna element with the best communication quality parameters is kept connected to the transceiver for subsequent data transmission. Since the antenna with the best directivity is used, the communication link quality is significantly optimized, and the communication quality between the antenna and the terminal is improved.

[0065] In an optional embodiment, when the number of target antenna elements is multiple, the method further includes: Based on the communication quality parameters, a preset number of candidate antenna elements are determined to achieve the best communication quality. Obtain the first spatial coordinates and radiation direction of the candidate antenna element; The second spatial coordinates of the terminal are determined based on the first spatial coordinates of the candidate antenna element, the radiation direction, and the communication quality parameters.

[0066] In some embodiments, since each antenna element is configured on the antenna, and the spatial position of each antenna element on the antenna can be determined after the antenna is installed, the spatial position of the terminal can be determined by the relevant information of multiple antenna elements connected to the terminal, thereby enabling precise positioning of the terminal.

[0067] The control unit determines a preset number (e.g., the first 3) of candidate antenna units with the best communication quality based on communication quality parameters. Since the spatial position of the antenna units is fixed, after determining the candidate antenna units, the first spatial coordinates, radiation direction and communication quality parameters of each candidate antenna unit can be obtained. The second spatial coordinates of the terminal are calculated using triangulation or fingerprint positioning algorithms.

[0068] In an optional embodiment, determining the second spatial coordinates of the terminal based on the first spatial coordinates of the candidate antenna element, the radiation direction, and the communication quality parameters includes: Based on the communication quality parameters, the communication delay between the candidate antenna and the terminal is determined; The communication length is determined based on the communication delay and the radiation direction; The second spatial coordinates are determined based on the communication length and the first spatial coordinates.

[0069] In some embodiments, the communication delay between each candidate antenna element and the terminal is determined, and the communication distance between the candidate antenna element and the terminal is determined using the communication delay and communication quality parameters. Based on the communication distance between each candidate antenna element and the terminal and the first spatial coordinates of the candidate antenna elements, the second spatial coordinates of the terminal are solved by using a set solution method with the first spatial coordinates as the origin and the communication distance as the radius.

[0070] The communication latency can be obtained by calculating the time difference between the moment the detection request is sent by the terminal and the moment the detection request is received by the antenna unit during a brief communication (such as a detection request) between the computing terminal and the antenna unit.

[0071] For example, taking a candidate antenna element count of three as an example, we can substitute the following formula: (x-x1) 2 +(y-y1) 2 =d1 2 ; (x-x2) 2 +(y-y2) 2 =d2 2 ; (x-x3) 2 +(y-y3) 2 =d32 ; Where x1 and y1 represent the abscissa and ordinate of the first candidate antenna element in the first spatial coordinate system, respectively; d1 represents the communication distance between the first candidate antenna element and the terminal; x2 and y2 represent the abscissa and ordinate of the second candidate antenna element in the first spatial coordinate system, respectively; d2 represents the communication distance between the second candidate antenna element and the terminal; x3 and y3 represent the abscissa and ordinate of the third candidate antenna element in the first spatial coordinate system, respectively; d3 represents the communication distance between the third candidate antenna element and the terminal; and x and y represent the abscissa and ordinate of the terminal in the second spatial coordinate system, respectively.

[0072] By determining the terminal's secondary spatial coordinates, it can be applied to precise indoor positioning, such as positioning a smart pen on a whiteboard and tracking people.

[0073] In one specific embodiment, the antenna control method of this application is described in [reference needed]. Figure 5 The antenna broadcasts information to determine if any device has initiated a connection. If not, it continues broadcasting. If so, it initiates an RSSI scanning process, uploads the scan results, and stores them in a mapping table. Each antenna element has a fixed radiation direction and periodically scans and uploads RSSI reporting information. It determines whether the optimal antenna element for RSSI has changed. If so, it changes the target antenna element through a logic control unit.

[0074] Omnidirectional directional scanning and signal tracking are achieved by setting up spherical antenna elements and using logic control methods. Any single antenna element can use this control method for signal tracking and positioning. The algorithm is simple and does not cause significant attenuation of antenna efficiency at certain angles. Simultaneously, it ensures that the antenna can directionally track wireless devices in real time, resulting in optimal radiation capabilities. There is no signal attenuation across the entire omnidirectional angle. When the antenna elements are highly consistent, indoor 3D positioning can also be achieved.
