Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] It should be noted that, in the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0055] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0056] The following explains the terms involved in the embodiments of the present application to facilitate the reader's understanding.

[0057] (1) In the perception scenario, the sending device radiates electromagnetic waves to the surrounding environment to send a perception signal, and the receiving device receives the perception signal reflected by the surrounding environment, and analyzes and compares it with the transmitted perception signal, so as to perceive relevant information of the surrounding environment, such as whether there are targets to be detected in the environment, the number of targets, the location of each target, etc. The reflected perception signal can also be called an echo signal, or an echo signal of the perception signal. Among them, the perception signal can be understood as a signal used to perceive (or detect) the perceived target. The perceived target can also be understood as a target object, such as a scatterer or a reflector.

[0058] (2) RIS, as a two-dimensional implementation of electromagnetic metamaterials, actively and intelligently regulates electromagnetic waves in space in a programmable manner to form an electromagnetic field with controllable amplitude, phase, polarization and frequency, which can change the wireless propagation environment from passive adaptation to active control. In the embodiment of the present application, in the RIS-assisted communication system, the signal sent by the base station is mainly forwarded to the terminal by reflection / transmission through the RIS, and the signal sent by the terminal can also be forwarded to the base station through the RIS. In the RIS-assisted communication system, the beam can be transmitted to the terminal in a specified direction through beamforming technology, so as to expand the coverage range of the signal and improve the signal communication quality. By dynamically adjusting the wireless channel environment through RIS, the transmission performance between communication devices can be significantly improved, and the coverage performance of the wireless communication system can be enhanced.

[0059] (3) Diffraction-free beam, an electromagnetic wave that propagates in space without diffraction. The diffraction-free beam has a self-healing property, that is, when the beam is blocked by a scatterer, it can be re-healed and restored to its original beam shape after a certain distance of transmission. In an embodiment of the present application, in a RIS-assisted communication system, based on RIS, the spherical wave emitted by the base station antenna can be converted into a diffraction-free wave with self-healing characteristics, and the diffraction-free beam can be dynamically controlled.

[0060] In order to meet the demand for spectrum resources in communication systems, high-frequency signals such as millimeter waves and terahertz will become potential working signals in the next generation of communication systems. However, high-frequency signals have large path losses and are easily affected by obstacles, rain and snow, and environmental absorption. To overcome the severe path loss of high-frequency signals, RIS can be deployed between base stations and terminals to improve the coverage breadth and depth of wireless signals.

[0061] Most of the existing electromagnetic waves will experience diffraction during the propagation process, which causes the energy of the electromagnetic waves to be more dispersed and the energy density to decrease during the propagation process. In high-frequency communication systems, when there are scatterers on the signal propagation path, the signal penetration is severely attenuated, resulting in a significant drop in signal strength, affecting the system coverage performance. Although, in the existing RIS-assisted high-frequency communication system, RIS can focus the beam to a specific direction where the terminal is located, which can solve the problem of signal obstruction between the base station and the terminal. However, when there is a scatterer between the RIS and the terminal, the terminal cannot normally receive the beam forwarded by the RIS, resulting in a decrease in signal quality.

[0062] In view of this, the beam adjustment method provided by the present application can obtain whether there is a scatterer between the target terminal and the beam adjustment device by acquiring the perception information between the target terminal and the beam adjustment device, and obtain the position of the scatterer when there is a scatterer, and determine the codeword information of the beam adjustment device based on the perception information, thereby forming a diffraction-free beam. Due to the self-healing characteristics of the diffraction-free beam, when there is a scatterer between the terminal and the beam adjustment device, the beam received by the terminal is not affected by the scatterer, thereby improving the beam coverage performance in the scenario where a scatterer exists, and improving the communication quality.

[0063] The implementation of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0064] Figure 1 A schematic diagram of the architecture of a beam adjustment method provided in an embodiment of the present application. Figure 1 As shown, the architecture includes: a base station 101, a beam adjustment device 102 and a target terminal 103.

[0066] In some embodiments, the base station 101 may provide communication services. Specifically, the base station 101 sends a beam to the target terminal 103 to implement communication between the base station 101 and the target terminal 103 .

[0067] In some embodiments, the base station 101 may be equipped with a sensing module for realizing the sensing analysis function. In the embodiment of the present application, the echo signal of the sensing signal may be analyzed to realize the positioning, imaging, and identification of the target terminal and the environmental scatterer.

[0068] It should be noted that the perception module can be integrated into the base station 101, or integrated into the beam adjustment device 102 or the target terminal 103, or can be an independent physical device, which is not limited in this embodiment of the present application. In the embodiment of the present application, the perception module is integrated into the base station 101 as an example for subsequent description.

[0069] In some embodiments, the base station 101 may be provided with a beam adjustment module for adjusting the beam to form a non-diffraction beam. The beam adjustment module may send codeword information to the beam adjustment device 102, the codeword information being used to instruct the beam adjustment device to adjust the beam to form a non-diffraction beam.

[0070] It should be noted that the beam adjustment module can be integrated into the base station 101, or integrated into the beam adjustment device 102 or the target terminal 103, or can be an independent entity device, which is not limited in the embodiments of the present application. In the case where the beam adjustment module is an independent entity device, the beam adjustment module can be connected to the base station 101, the beam adjustment device 102 and the perception module through a communication link. The communication link can be a wired communication link or a wireless communication link, which is not limited in the present application.

[0071] In the embodiment of the present application, the beam adjustment module is integrated into the base station 101 as an example for subsequent description.

[0073] In some embodiments, the target terminal 103 may have a communication function, such as a communication function between the base station 101 and the target terminal 103 .

[0074] The beam adjustment device 102 is an auxiliary communication device in the wireless communication system, which is equipped with multiple electromagnetic units and can realize the regulation of the electromagnetic units and the forwarding of wireless signals. The beam adjustment device 102 can receive the downlink or uplink signal beam transmitted by the base station 101 or the target terminal 103, and forward the received downlink or uplink signal beam by reflection or transmission. It can be understood that the beam adjustment device 102 can be regarded as a transfer device between the base station 101 and the target terminal 103. Specifically, the beam adjustment device 102 receives the downlink signal beam transmitted by the base station 101, and transmits the downlink signal beam to the target terminal 103 by reflection or transmission; or, the beam adjustment device 102 receives the uplink signal beam sent by the target terminal 103, and transmits the uplink signal beam to the base station 101 by reflection or transmission.

[0075] The beam adjustment device 102 may be a communication device such as a RIS, a network controlled repeater (NCR), etc., which is not limited in the embodiment of the present application.

[0076] It should be noted that the beam adjustment device 102 can be an independent device or integrated into a base station, and the embodiment of the present application is not limited to this. It is understandable that when the beam adjustment device 102 is an independent device, the beam adjustment device 102 needs to be located within the signal coverage range of the base station 101. In the embodiment of the present application, the beam adjustment device 102 is described below by taking an independent device as an example.

[0077] Taking the beam adjustment module and the perception module located in the base station 101 as an example, the corresponding beam adjustment implementation process can be: first, the base station 101 obtains the perception information between the target terminal 103 and the beam adjustment device 102 through the perception analysis function; then, the base station 101 determines the codeword information of the beam adjustment device 102 based on the perception information, and sends the codeword information to the beam adjustment device 102; finally, the beam adjustment device 102 forms a diffraction-free beam based on the codeword information, and transmits the diffraction-free beam to the target terminal 103.

[0078] The base station 101, the beam adjustment device 102 and the target terminal 103 are connected via a communication link. The communication link may be a wired communication link or a wireless communication link, which is not limited in the present application.

[0079] When implemented by hardware, when the beam adjustment module is integrated into the base station, the beam adjustment device and the target terminal or the beam adjustment module is an independent entity device, it can be provided as follows: Figure 2 The hardware structure shown, specifically, Figure 2 The hardware structure diagram of an electronic device provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the electronic device includes at least one processor 201, a communication line 202, and at least one communication interface 204, and may also include a memory 203. The processor 201, the memory 203 and the communication interface 204 may be connected via the communication line 202.

[0080] The processor 201 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), or one or more integrated circuits configured to implement the embodiments of the present application, such as one or more digital signal processors (DSP), or one or more field programmable gate arrays (FPGA).

[0081] The communication line 202 is used to transmit information between the above components.

[0082] The communication interface 204 is used to communicate with other devices or communication networks, and can use any transceiver-like device, such as Ethernet, radio access network (RAN), wireless local area network (WLAN), etc.

[0083] The memory 203 may be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a random access memory (RAM) or other types of dynamic storage devices that can store information and instructions, or an electrically erasable programmable read-only memory (EEPROM), a compact disc read-only memory (CD-ROM) or other optical disc storage, an optical disc storage (including compressed optical discs, laser discs, optical discs, digital versatile discs, Blu-ray discs, etc.), a magnetic disk storage medium or other magnetic storage device, or any other medium that can be used to include or store desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited to these.

[0084] In one possible design, the memory 203 can exist independently of the processor 201, that is, the memory 203 can be a memory outside the processor 201. In this case, the memory 203 can be connected to the processor 201 through the communication line 202, and is used to store execution instructions or application code, and the processor 201 controls the execution to implement the beam adjustment method provided in the following embodiment of the present application. In another possible design, the memory 203 can also be integrated with the processor 201, that is, the memory 203 can be the internal memory of the processor 201, for example, the memory 203 is a high-speed cache, which can be used to temporarily store some data and instruction information.

[0085] As a possible implementation, the processor 201 may include one or more CPUs, for example Figure 2 As another possible implementation, the electronic device may include multiple processors, such as Figure 2 As another possible implementation, the electronic device may further include an output device 205 and an input device 206.

[0086] It should be pointed out that the various embodiments of the present application can learn from or refer to each other. For example, the same or similar steps, method embodiments, system embodiments and device embodiments can all refer to each other without limitation.

[0087] The embodiment of the present application takes the base station including a beam adjustment module and a perception module as an example for subsequent description.

[0088] Figure 3 A flow chart of a beam adjustment method provided in an embodiment of the present application, which can be applied to Figure 2 In the electronic device shown, such as a base station, a beam adjustment device, a target terminal or an independent entity device. Figure 3 As shown, taking the base station as the execution subject as an example, the method includes the following steps:

[0089] S301. The base station obtains perception information between the target terminal and the beam adjustment device.

[0090] Among them, the perception information between the target terminal and the beam adjustment device is used to indicate whether there is a scatterer and the position of the scatterer when there is a scatterer. The scatterer is an obstacle that hinders the propagation of the beam.

[0091] In a possible implementation, the implementation process of step S301 may be:

[0092] Step 1: Based on the location of the target terminal and the location of the beam adjustment device, the base station determines the coverage area with the beam adjustment device as the starting point, the line connecting the beam adjustment device and the target terminal as the center line, and the preset angle as the deflection angle as the target perception area.

[0093] Step 2: The base station performs perception analysis on the target perception area to obtain perception information of the target perception area as the perception information between the target terminal and the beam adjustment device.

[0094] In this way, by defining the scope of the target perception area, the perception information between the target terminal and the beam adjustment device can be accurately obtained, and by defining the scope of the target perception area, the perception analysis of areas outside the target perception area can be avoided, reducing resource waste and thus improving the efficiency of beam adjustment.

[0095] By acquiring perception information, it is possible to identify whether there is a scatterer between the target terminal and the beam adjustment device and the position of the scatterer when there is a scatterer, and to provide reference information for generating codeword information so that a diffraction-free light beam can be subsequently generated based on the codeword information.

[0096] S302. The base station determines codeword information of the beam adjustment device based on the perception information.

[0097] The codeword information is used to instruct the beam adjustment device to adjust the beam to form a non-diffraction beam.

[0098] Specifically, the implementation process of the above step S302 may be:

[0099] Step 1: The base station determines the location of the scatterer between the target terminal and the beam adjustment device based on the sensing information.

[0100] Step 2: The base station determines the codeword information based on the location of the scatterer.

[0101] In this way, by determining the position of the scatterer between the target terminal and the beam adjustment device, the code information can be determined based on the position of the scatterer, and a diffraction-free beam can be generated based on the code information. Due to the self-healing characteristics of the diffraction-free beam, when the beam encounters a scatterer during transmission, the beam can be reconstructed to improve communication quality.

[0102] S303: Based on the codeword information, control the beam adjustment device to transmit a diffraction-free beam to the target terminal.

[0103] Exemplarily, when the beam adjustment module is integrated in the base station or the target terminal, the process of the above step S303 may be that the base station or the target terminal sends the codeword information to the beam adjustment device. Accordingly, the beam adjustment device receives the codeword information, generates a non-diffraction beam based on the codeword information, and transmits the non-diffraction beam to the target terminal. Accordingly, the target terminal receives the non-diffraction beam.

[0104] Exemplarily, when the beam adjustment module is integrated into the beam adjustment device, the process of step S303 may be that the beam adjustment device generates a non-diffraction beam based on the codeword information and transmits the non-diffraction beam to the target terminal. Accordingly, the target terminal receives the non-diffraction beam.

[0105] Exemplarily, when the beam adjustment module is an independent entity device, the process of the above step S303 may be that the entity device sends the codeword information to the beam adjustment device. Accordingly, the beam adjustment device receives the codeword information, and the beam adjustment device generates a non-diffraction beam based on the codeword information, and transmits the non-diffraction beam to the target terminal. Accordingly, the target terminal receives the non-diffraction beam.

[0106] In this way, by transmitting a diffraction-free beam to the target terminal, the signal attenuation problem caused by signal obstruction caused by scatterers in the signal propagation path is solved, the strength of the signal received by the target terminal can be increased, and the user experience can be improved.

[0107] The beam adjustment method provided in the present application can obtain whether there is a scatterer between the target terminal and the beam adjustment device by acquiring the perception information between the target terminal and the beam adjustment device, and obtain the position of the scatterer when there is a scatterer, and determine the codeword information of the beam adjustment device based on the perception information, thereby forming a diffraction-free beam. Due to the self-healing characteristics of the diffraction-free beam, when there is a scatterer between the terminal and the beam adjustment device, the beam received by the terminal is not affected by the scatterer, thereby improving the beam coverage performance in the scenario where the scatterer exists, and improving the communication quality.

[0108] Figure 4 A flowchart of another beam adjustment method provided in an embodiment of the present application, which can be applied to Figure 2 In the electronic device shown. Figure 4 As shown, the method comprises the following steps:

[0109] S401: The base station determines a target terminal.

[0110] It should be noted that within the signal coverage of the beam adjustment device, there are multiple terminals, and the process of determining the target terminal may be:

[0111] Step 1: The base station obtains the signal strengths of multiple terminals and the distances between the multiple terminals and the beam adjustment device.

[0112] In a possible implementation manner, the base station obtains the signal strength of the terminal by receiving a measurement report sent by the terminal, wherein the measurement report carries the signal strength of the terminal.

[0113] In a possible implementation, the base station determines the location of the terminal by using a base station positioning technology, and the base station determines the distance between the terminal and the beam adjustment device based on the location of the terminal and the location of the beam adjustment device.

[0114] In another possible implementation, the terminal determines the location of the terminal through a global positioning system (GPS) and sends the location of the terminal to the base station. The base station determines the distance between the terminal and the beam adjustment device based on the location of the terminal and the location of the beam adjustment device.

[0115] It should be noted that the position of the beam adjustment device may be pre-stored in the base station.

[0116] Step 2: From multiple terminals, determine a terminal whose signal strength is less than a signal strength threshold and whose distance is less than a distance threshold as a target terminal.

[0117] The signal strength threshold is used to determine the signal quality of the terminal. For example, if the signal strength of the terminal is less than the signal strength threshold, it means that the signal quality of the terminal is poor; if the signal strength of the terminal is greater than or equal to the signal strength threshold, it means that the signal quality of the terminal is good.

[0118] The distance threshold is used to determine the distance between the terminal and the beam adjustment device. For example, if the distance between the terminal and the beam adjustment device is less than the distance threshold, it means that the terminal is close to the beam adjustment device; if the distance between the terminal and the beam adjustment device is greater than or equal to the distance threshold, it means that the terminal is far from the beam adjustment device.

[0119] In a possible implementation, the distance threshold may be a Rayleigh distance. The Rayleigh distance may be calculated based on the following formula (1) according to the maximum size of the antenna of the beam adjustment device and the wavelength of the beam to be transmitted of the beam adjustment device.

[0120] d=2D 2 / λ (1)

[0121] Wherein, d represents the Rayleigh distance, D represents the maximum size of the antenna of the beam adjustment device, and λ represents the wavelength of the beam to be transmitted of the beam adjustment device.

[0122] It should be noted that the signal coverage range of the beam adjustment device is the signal coverage range of the base station after forwarding by the beam adjustment device, which can also be roughly understood as the signal coverage range of the base station. The signal coverage range of the beam adjustment device can be divided into a near-field area and a far-field area. When the distance between the terminal and the beam adjustment device is less than the Rayleigh distance, the terminal can be considered to be in the near-field area of ​​the beam adjustment device; when the distance between the terminal and the beam adjustment device is greater than or equal to the Rayleigh distance, the terminal can be considered to be in the far-field area of ​​the beam adjustment device.

[0123] It can be understood that when the terminal signal strength is less than the signal strength threshold and the distance is less than the distance threshold, it means that the terminal is close to the beam adjustment device but the signal strength is poor. It can be approximately considered that there is a scatterer in the signal transmission path between the terminal and the beam adjustment device, which hinders the beam transmission. Therefore, the terminal is determined as the target terminal.

[0124] In addition, when the beam adjustment module is an independent entity device, the beam adjustment module can obtain the target terminal by exchanging information with the base station. Exemplarily, the beam adjustment module sends a terminal request message to the base station, and the terminal request message is used to obtain the target terminal. In response to the terminal request message, the base station sends a terminal response message to the beam adjustment module, and the terminal response message includes the target terminal.

[0125] In this way, by screening the signal strength and distance, it is possible to determine the terminals with scatterers in the signal transmission path, and to perform beam adjustments on the terminals with scatterers in the signal transmission path in a targeted manner, thereby avoiding beam adjustments on terminals without scatterer interference in the signal transmission path, thereby reducing resource waste and improving efficiency.

[0126] S402. Based on the location of the target terminal and the location of the beam adjustment device, the base station determines a coverage area with the beam adjustment device as the starting point, the line connecting the beam adjustment device and the target terminal as the center line, and the preset angle as the deflection angle, as the target perception area.

[0127] S403: The base station performs perception analysis on the target perception area to obtain perception information of the target perception area as perception information between the target terminal and the beam adjustment device.

[0128] The base station sends a perception beam to the target perception area via a beam adjustment device. After the perception beam is beam scanned in the target perception area, the base station receives an echo beam forwarded by the beam adjustment device, and obtains perception information of the target perception area after perception analysis of the echo beam.

[0129] Specifically, the specific implementation process of the above step S403 may be:

[0130] Step 1: The base station sends a sensing beam and a sensing beam control message to the beam adjustment device.

[0131] The sensing beam control message is used to instruct the sensing beam to perform beam scanning in the target sensing area. The sensing beam control message carries a sensing codebook, in which a set of sensing codewords is preset, and the sensing codewords are used to instruct to adjust the transmission direction of the sensing beam to complete beam scanning in different directions.

[0132] Exemplarily, the perceptual codebook can be expressed as {C 1 , C 2 , …C N / 2 , …, C N}, where N represents the number of beam scans. N / 2 represents the center codeword, which corresponds to the transmission direction of the perception beam after adjustment, which is the direction of the connection between the beam adjustment device and the target terminal, that is, the center line direction. The transmission direction of the N perception beams corresponding to the perception codebook is represented by {a 1 , a 2 , …a N / 2 , …, a N}, where a i+1 -a i =α / N and a N -a 1 =α, α is the preset angle.

[0133] Accordingly, the beam adjustment device receives the sensing beam and the sensing beam control message.

[0134] Step 2: The beam adjustment device sends a sensing beam to the target sensing area based on the sensing beam control message to perform beam scanning.

[0135] Step 3: The base station receives the echo beam forwarded by the beam adjustment device, and performs perception analysis on the echo beam to obtain perception information of the target perception area as the perception information between the target terminal and the beam adjustment device.

[0136] It can be understood that since the beam to be transmitted between the target terminal and the base station is forwarded via the beam adjustment device, the perception beam is also forwarded via the beam adjustment device in the process of acquiring the perception information. In this way, the transmission channel environment of the perception beam and the beam to be transmitted can be basically similar, so that the scatterers existing on the transmission path of the beam to be transmitted can be accurately identified, and the signal blocking problem caused by the scatterers can be further solved.

[0137] In addition, when the beam adjustment module and the perception module are independent entity devices, the beam adjustment module can obtain the perception information of the target perception area by exchanging information with the perception module. Exemplarily, the beam adjustment module sends a perception request message to the perception module, and the perception request message includes information of the target perception area, which is used to obtain the perception information of the target perception area. In response to the perception request message, the perception module sends a perception response message to the beam adjustment module, and the perception response message includes the perception information of the target perception area.

[0138] S404. The base station determines the position of the scatterer between the target terminal and the beam adjustment device based on the sensing information.

[0139] Exemplarily, the position of the scatterer between the target terminal and the beam adjustment device can be determined by processing the arrival angle and signal strength of the echo beam.

[0140] It can be understood that the scatterer is located within the target sensing area, that is, the horizontal distance between the scatterer and the beam adjustment device is less than or equal to the horizontal distance between the target terminal and the beam adjustment device.

[0141] S405. The base station determines the diffraction-free propagation distance based on the position of the target terminal and the position of the beam adjustment device.

[0142] The diffraction-free propagation distance is used to indicate the propagation distance over which the diffraction-free beam energy does not diffract.

[0143] In a possible implementation, the specific implementation process of step S405 may be:

[0144] Step 1: Based on the position of the target terminal and the position of the beam adjustment device, determine the horizontal distance between the target terminal and the beam adjustment device.

[0145] Step 2: Based on the horizontal distance between the target terminal and the beam adjustment device, determine the diffraction-free propagation distance, and the diffraction-free propagation distance is greater than or equal to the horizontal distance.

[0146] Exemplarily, the horizontal distance between the target terminal and the beam adjustment device is represented by L, and the propagation distance Z with or without diffraction is max Meet Z max ≥L.

[0147] In this way, the location of the target terminal can be covered within the diffraction-free propagation distance, so that the diffraction-free beam formed by subsequently determining the codeword information based on the diffraction-free propagation distance can reach the location of the terminal, thereby improving the signal strength of the target terminal.

[0148] S406. The base station determines a self-healing distance based on the position of the target terminal and the position of the scatterer.

[0149] The self-healing distance is used to indicate the propagation distance required for a diffraction-free beam to self-recover after encountering a scatterer.

[0150] In a possible implementation, the specific implementation process of step S406 may be:

[0151] Step 1: Based on the position of the target terminal and the position of the scatterer, determine the horizontal distance between the target terminal and the scatterer.

[0152] Step 2: Based on the horizontal distance between the target terminal and the scatterer, determine the self-healing distance, which is less than or equal to the horizontal distance.

[0153] Exemplarily, the horizontal distance between the target terminal and the scatterer is represented by S, and the self-healing distance Z is 0 Meet Z 0 ≥S.

[0154] It should be noted that, when there are multiple scatterers in the target sensing area, the horizontal distance between the target terminal and the scatterers is the horizontal distance between the scatterer closest to the target terminal and the target terminal.

[0155] In this way, the self-healing distance is no greater than the horizontal distance between the target terminal and the scatterer, so that the beam can achieve self-healing before reaching the location of the target terminal, so that the energy of the beam can be refocused. The codeword information is subsequently determined based on the self-healing distance to form a diffraction-free beam that is not blocked by the scatterer, thereby improving the signal strength of the target terminal.

[0156] It should be noted that there is no strict order between the above-mentioned step S405 and step S406. Step S405 can be executed first and then step S406, or step S406 can be executed first and then step S406, or step S405 and S406 can be executed at the same time. This application does not make any specific limitations on this.

[0157] S407: Determine codeword information based on the diffraction-free propagation distance, the self-healing distance, the signal frequency of the beam to be transmitted of the beam adjustment device, and the antenna aperture of the beam adjustment device.

[0158] The codeword information is used to instruct the beam adjustment device to be adjusted to form a non-diffraction beam. The codeword information includes a phase parameter corresponding to each electromagnetic unit of the beam adjustment device.

[0159] Exemplarily, taking the beam to be transmitted as a Bessel beam as an example, the process of determining the codeword information may be:

[0160] According to the optical wave propagation theory and the principle of non-diffraction beam generation, when the spherical wave emitted by the base station is formed into a non-diffraction beam by a beam adjustment device, the phase parameter corresponding to each electromagnetic unit can be determined based on the following formula (2).

[0161]

[0162] In the formula, θ i (f) represents the phase parameter corresponding to the i-th electromagnetic unit, F represents the distance between the base station and the beam adjustment device, D represents the maximum aperture of the antenna of the beam adjustment device, and Z max represents the diffraction-free propagation distance, f represents the signal frequency of the beam to be transmitted, c represents the speed of light, ρ represents the distance from the i-th electromagnetic unit in the beam adjustment device to the center of the antenna panel of the beam adjustment device, and ε r Represents the dielectric constant of the propagation medium during beam transmission.

[0163] In this way, through the codeword information determined by the diffraction-free propagation distance and the self-healing distance, the diffraction-free beam generated based on the codeword information can achieve beam self-healing after encountering a scatterer, and the target terminal is located within the coverage range of the diffraction-free beam, which can improve the beam coverage performance in communication scenarios where scatterers exist.

[0164] S408. The base station sends codeword information to the beam adjustment device.

[0165] Exemplarily, the base station may send a codeword control message to the beam adjustment device, the codeword control message carrying the codeword information or the beam identification code corresponding to the codeword information. The beam identification code corresponds to the codeword information one-to-one, and the correspondence between the codeword information and the beam identification code may be pre-stored in the base station and the beam adjustment device.

[0166] Accordingly, the beam adjustment device receives the codeword information.

[0167] S409: The beam adjustment device generates a corresponding non-diffraction beam based on the codeword information.

[0168] Exemplarily, the beam adjustment device adjusts the phase of each electromagnetic unit according to the codeword information to adjust the beam to be transmitted, and converts the spherical beam emitted by the base station into a non-diffraction beam.

[0169] Based on the codeword information, the deflection angle of the diffraction-free beam is dynamically adjusted so that the diffraction-free beam points in the direction of the target terminal after deflection; the diffraction-free propagation distance of the diffraction-free beam is dynamically adjusted so that the target terminal is located within the diffraction-free propagation distance; the self-healing distance of the diffraction-free beam is dynamically adjusted so that the diffraction-free beam can achieve self-healing before reaching the location of the target terminal.

[0170] The beam adjustment method provided in the present application can obtain whether there is a scatterer between the target terminal and the beam adjustment device by acquiring the perception information between the target terminal and the beam adjustment device, and obtain the position of the scatterer when there is a scatterer, and determine the codeword information of the beam adjustment device based on the perception information, thereby forming a diffraction-free beam. Due to the self-healing characteristics of the diffraction-free beam, when there is a scatterer between the terminal and the beam adjustment device, the beam received by the terminal is not affected by the scatterer, thereby improving the beam coverage performance in the scenario where the scatterer exists, and improving the communication quality.

[0171] In the above embodiment, by determining the terminal that is close to the beam adjustment device but has poor signal strength as the target terminal, it is possible to determine the terminal with a scatterer in the signal transmission path, and to perform beam adjustment on the terminal with a scatterer in the signal transmission path in a targeted manner. Based on the perception information of the target perception area, the target codeword is determined to generate a diffraction-free beam, and the generated diffraction-free beam can achieve beam self-healing after encountering a scatterer. The target terminal is located within the coverage range of the diffraction-free beam, which can improve the beam coverage performance in communication scenarios where scatterers exist.
