[0050] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. 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) 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 beamforming technology can be used to transmit the beam to the terminal in a specified direction, thereby expanding the signal coverage and improving 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.

[0058] 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. In order to achieve higher array gain, RIS can use ultra-large-scale antenna arrays in combination with higher-frequency signals such as millimeter waves and terahertz.

[0059] According to electromagnetic field theory, the electromagnetic field radiated by the antenna of the base station can be divided into a near-field region and a far-field region. The introduction of high-frequency and large-size RIS makes it possible for the near-field region of the base station to reach tens of meters or even hundreds of meters, which makes the near-field characteristics of electromagnetic waves significant. In the fourth generation mobile communication technology (4G) / fifth generation mobile communication technology (5G), the near-field region of a traditional base station may be only a few meters. In this case, the terminal is usually located in the far-field region covered by the traditional base station. In the RIS-assisted communication system, due to the increase in the coverage range of the near-field region of the base station, the terminal can be located not only in the far-field region, but also in the near-field region.

[0060] There are essential differences between the propagation characteristics of electromagnetic waves in the near field and the far field. The electromagnetic waves in the far field follow the plane wave model, while the electromagnetic wave propagation in the near field is based on the spherical wave model. For the plane wave model, only its angle can be controlled. RIS uses beamforming technology to control the beam angle to point the beam to the terminal in a specific direction. The biggest difference between the spherical wave model and the plane wave model is that the spherical wave is not only related to the angle, but also to the distance. That is to say, in the spherical wave model, it can be controlled in two dimensions: angle and distance. Based on this, unlike traditional far-field beamforming, near-field beamforming can control the direction and distance of the beam at the same time, so that the electromagnetic beam is focused in both the angle domain and the distance domain, thereby assisting the wireless network to achieve more accurate signal coverage and improve communication quality.

[0061] The beamforming method used by the existing RIS-assisted communication system is mainly used in the far field area. Due to the different electromagnetic wave propagation models in the far field area and the near field area, the existing beamforming method cannot be used in both the near field area and the far field area at the same time, which will lead to a decrease in beam control accuracy and impaired coverage performance.

[0062] In view of this, the beam adjustment method provided in the present application can obtain the first area or the second area within the signal coverage range of the beam adjustment device where the terminal is located by acquiring the area information of the terminal. By determining different codeword information for different areas where the terminal is located, differentiated matching of codeword information in different areas can be achieved, thereby improving the accuracy of beam control, thereby meeting the communication needs of terminals located in different areas and improving user experience.

[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 terminal 103.

[0065] Base station 101 can be a base station or evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station device in a fifth generation mobile communication technology (5G) network, a base station device in an evolution and enhancement network of a 5G network (5G-advanced, 5G-A), or a base station in a future communication system, etc. The base station may include various network side devices such as various macro base stations, micro base stations, home base stations, wireless remote devices, wireless fidelity (WIFI) devices, etc., and the embodiments of the present disclosure are not limited to this.

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

[0067] In some other embodiments, the base station 101 may provide a storage function. For example, the base station 101 stores the area information of the terminal 103 for subsequent flexible access.

[0068] In some embodiments, the base station 101 may be provided with a beam adjustment module for adjusting the beam to be transmitted. The beam adjustment module may send codeword information to the beam adjustment device 102, and the codeword information is used to instruct the beam adjustment device to adjust the beam to be transmitted.

[0069] 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 terminal 103, or can be an independent entity device, and the embodiment of the present application does not limit this. 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 and the beam adjustment device 102 through a communication link. The communication link can be a wired communication link or a wireless communication link, and the present application does not limit this.

[0070] In the embodiment of the present application, the beam adjustment module is integrated into the base station 101 as an example for subsequent description.

[0071] The terminal 103 is a device with wireless transceiver function, which can be at least one of a mobile phone, a smart watch, a tablet computer (pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal and a laptop computer, etc., and the embodiments of the present application are not limited to this.

[0072] In some embodiments, the terminal 103 may have a communication function, such as a communication function between the base station 101 and the terminal 103 .

[0073] 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 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 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 terminal 103 by reflection or transmission; or, the beam adjustment device 102 receives the uplink signal beam sent by the terminal 103, and transmits the uplink signal beam to the base station 101 by reflection or transmission.

[0074] 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.

[0075] 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.

[0076] Taking the beam adjustment module integrated in the base station 101 as an example, the corresponding beam adjustment implementation process can be: first, the base station 101 obtains the area information of the terminal; then, the base station 101 determines the codeword information corresponding to the terminal 103 based on the area information, and sends the codeword information to the beam adjustment device 102; finally, the beam adjustment device 102 adjusts the transmission beam based on the codeword information, and transmits the adjusted transmission beam to the terminal 103.

[0077] The base station 101, the beam adjustment device 102 and the 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.

[0078] 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.

[0079] 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).

[0080] The communication line 202 is used to transmit information between the above components.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] The embodiment of the present application takes the base station including a beam adjustment module as an example for subsequent description.

[0087] 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:

[0088] S301. A base station obtains area information of a terminal.

[0089] The area information is used to indicate that the terminal is located in a first area or a second area within the signal coverage range of the beam adjustment device, and the distance between the first area and the beam adjustment device is smaller than the distance between the second area and the beam adjustment device.

[0090] In a possible implementation, the implementation process of step S301 may be:

[0091] Step 1: 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.

[0092] In a possible implementation, the base station determines the location of the terminal by using a base station positioning technology, and 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.

[0093] 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.

[0094] It should be noted that the position of the beam adjustment device may be pre-stored in the base station.

[0095] Step 2: If the distance is less than or equal to the distance threshold, it is determined that the terminal is located in the first area within the signal coverage range of the beam adjustment device; if the distance is greater than the distance threshold, it is determined that the terminal is located in the second area within the signal coverage range of the beam adjustment device.

[0096] The distance threshold is used to determine the area where the terminal is located.

[0097] In a possible implementation, the distance threshold may be determined based on the antenna size of the beam adjustment device and the signal wavelength of the beam to be transmitted.

[0098] Exemplarily, 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.

[0099] d=2D 2 / λ (1)

[0100] 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.

[0101] In this way, determining the distance threshold based on the antenna size of the beam adjustment device and the signal wavelength of the beam to be transmitted can provide a data basis for determining different areas and facilitate further determination of the area where the terminal is located.

[0102] 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 threshold is the Rayleigh distance, when the distance between the terminal and the beam adjustment device is less than or equal to 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 the Rayleigh distance, the terminal can be considered to be in the far-field area of ​​the beam adjustment device.

[0103] In this way, the area within the signal coverage range of the beam adjustment device where the terminal is located is determined by the distance between the terminal and the beam adjustment device, thereby providing area information for subsequent determination of codeword information, thereby facilitating generation of codeword information corresponding to the terminal based on different area information.

[0104] In addition, when the beam adjustment module is an independent entity device, the beam adjustment module can obtain the area information of the terminal by exchanging information with the base station. Exemplarily, the beam adjustment module sends a terminal area request message to the base station, and the terminal area request message is used to obtain the area information of the terminal. In response to the terminal area request message, the base station sends a terminal area response message to the beam adjustment module, and the terminal area response message includes the area information of the terminal.

[0105] By determining the area information of the terminal, it can be used to determine whether the terminal is located in the first area or the second area within the signal coverage range of the beam adjustment device. On this basis, it is convenient to subsequently generate corresponding codewords for terminals located in different areas, thereby improving the beam coverage performance.

[0106] S302: The base station determines codeword information corresponding to the terminal based on the area indicated by the area information of the terminal.

[0107] The codeword information is used to instruct the beam adjustment device to adjust the beam to be transmitted.

[0108] In a possible implementation, the specific implementation process of step S302 can be divided into the following two cases:

[0109] Case 1: When the terminal is located in the first area within the signal coverage of the beam adjustment device, codeword information corresponding to the terminal is determined based on the distance and azimuth between the terminal and the beam adjustment device.

[0110] The azimuth angle is the angle between the line connecting the terminal and the beam adjustment device and the preset direction, starting from the beam adjustment device.

[0111] In a possible implementation, the preset direction may be north.

[0112] In this way, based on the first area where the terminal is located within the signal coverage range of the beam adjustment device, the codeword information corresponding to the terminal can be determined from two dimensions of distance and azimuth, thereby improving the accuracy of beam control.

[0113] Case 2: When the terminal is located in the second area within the signal coverage of the beam adjustment device, the codeword information corresponding to the terminal is determined based on the azimuth.

[0114] The azimuth angle is the angle between the line connecting the terminal and the beam adjustment device and the preset direction, starting from the beam adjustment device.

[0115] In a possible implementation, the preset direction may be north.

[0116] In this way, based on the fact that the terminal is located in the second area within the signal coverage range of the beam adjustment device, the codeword information corresponding to the terminal can be determined based on the azimuth angle, thereby improving the performance of the beam coverage.

[0117] S303: Based on the codeword information, control the beam adjustment device to adjust the beam to be transmitted.

[0118] Exemplarily, when the beam adjustment module is integrated in a base station or a terminal, the process of the above step S303 may be that the base station or the terminal sends the codeword information to the beam adjustment device. Accordingly, the beam adjustment device receives the codeword information, and the beam adjustment device adjusts the beam to be transmitted based on the codeword information, and transmits the adjusted beam to be transmitted to the terminal. Accordingly, the terminal receives the adjusted beam to be transmitted.

[0119] 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 adjusts the beam to be transmitted based on the codeword information and transmits the adjusted beam to be transmitted to the terminal. Correspondingly, the terminal receives the adjusted beam to be transmitted.

[0120] 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 adjusts the beam to be transmitted based on the codeword information, and transmits the adjusted beam to be transmitted to the terminal. Accordingly, the terminal receives the adjusted beam to be transmitted.

[0121] The beam adjustment method provided in the present application can obtain the first area or the second area within the signal coverage range of the beam adjustment device where the terminal is located by acquiring the area information of the terminal. By determining different codeword information for different areas where the terminal is located, differentiated matching of codeword information in different areas can be achieved, thereby improving the accuracy of beam control, thereby meeting the communication needs of terminals located in different areas and improving user experience.

[0122] The following is an introduction to the process of implementing beam adjustment in situation one.

[0123] Step 1: Based on the distance and azimuth between the terminal and the beam adjustment device, determine the codeword information corresponding to the terminal.

[0124] The codeword information includes a phase parameter corresponding to each electromagnetic unit of the beam adjustment device.

[0125] In one possible implementation, channel state information between the beam adjustment device and the terminal is determined based on the distance and azimuth between the terminal and the beam adjustment device, where the channel state information is used to indicate the state and characteristics of the channel; and codeword information corresponding to the channel state information is determined as the codeword information corresponding to the terminal.

[0126] Exemplarily, the base station presets a codebook for adjusting the beam to be transmitted, and the codebook contains multiple codeword information. An array of a preset azimuth interval and a preset distance interval corresponds to a sub-codebook in the codebook. For example, [α±θ,l±a] represents an array of a preset azimuth interval and a preset distance interval.

[0127] After the beam adjustment device adjusts the beam to be transmitted based on the codebook, the beam can cover the area covered by the beam adjustment device.

[0128] It is understandable that due to the existence of measurement errors, such as the measurement deviation of the azimuth angle, the accuracy of the distance calculation between the terminal and the beam adjustment device, etc., there are certain errors in the calculated azimuth angle and distance compared with the actual situation. Therefore, an array of preset azimuth angle intervals and preset distance intervals is used to minimize the error.

[0129] Based on the distance and azimuth between the terminal and the beam adjustment device, determine the array of preset azimuth intervals and preset distance intervals corresponding to the distance and azimuth between the terminal and the beam adjustment device, that is, determine the corresponding sub-codebook. At different times, send each codeword information in the sub-codebook to the beam adjustment device in turn. The beam adjustment device adjusts the phase of each electromagnetic unit of the beam adjustment device based on each codeword information, thereby adjusting the beam to be transmitted and obtaining the adjusted beam to be transmitted. The adjusted beam to be transmitted is sent to the terminal. After the terminal receives the adjusted beam to be transmitted, it measures the channel state information between the beam adjustment device and the terminal corresponding to the codeword information, such as signal amplitude, phase, multipath delay, frequency deviation, etc., and reports the channel state information to the base station. After traversing all the codeword information in the sub-codebook, the base station processes the channel state information reported by the terminal, thereby determining the codeword information corresponding to the channel state information in the sub-codebook as the codeword information corresponding to the terminal.

[0130] It should be noted that when the beam to be transmitted is adjusted based on the codeword information corresponding to the terminal and the beam is transmitted to the terminal, the beam can not only point in the direction of the terminal, but also maximize the beam energy at the terminal.

[0131] In this way, based on the channel state information between the beam adjustment device and the terminal, the codeword information corresponding to the channel state information is determined, so that the beam to be transmitted adjusted based on the codeword information can be finely focused on a specific direction and the beam energy can be focused on a special position, that is, the direction and position of the terminal, thereby improving the beam coverage performance.

[0132] In another possible implementation, based on the distance and azimuth between the terminal and the beam adjustment device, codeword information corresponding to the terminal is determined through beam training technology.

[0133] Exemplarily, the base station presets a codebook for adjusting the beam to be transmitted, and the codebook contains multiple codeword information. An array of a preset azimuth angle and a preset distance corresponds to a sub-codebook in the codebook. For example, [α, l] represents an array of a preset azimuth angle and a preset distance.

[0134] Based on the distance and azimuth between the terminal and the beam adjustment device, determine the subcodebook corresponding to the array based on the distance and azimuth between the terminal and the beam adjustment device. At different times, send each codeword information in the subcodebook to the beam adjustment device in turn. The beam adjustment device adjusts the phase of each electromagnetic unit of the beam adjustment device based on each codeword information, thereby adjusting the beam to be transmitted and obtaining the adjusted beam to be transmitted. The adjusted beam to be transmitted is sent to the terminal. After the terminal receives the adjusted beam to be transmitted, it measures the signal strength corresponding to the codeword information and reports the signal strength to the base station. After traversing all the codeword information in the subcodebook, the base station determines the codeword information corresponding to the largest signal strength as the codeword information corresponding to the terminal based on the signal strength reported by the terminal.

[0135] It should be noted that when the beam to be transmitted is adjusted based on the codeword information corresponding to the terminal and the beam is transmitted to the terminal, the beam can not only point in the direction of the terminal, but also maximize the beam energy at the terminal.

[0136] In this way, based on the beam training technology, the codeword information corresponding to the terminal is determined, so that the transmission beam adjusted based on the codeword information can be focused in a specific direction and the beam energy can be focused on a special position, that is, the direction and position of the terminal, thereby improving the beam coverage performance.

[0137] In addition, when the first area is a near-field area, the codeword information corresponding to the terminal is determined based on the distance and azimuth between the terminal and the beam adjustment device, which is called a near-field codeword. After the phase of each electromagnetic unit of the beam adjustment device is adjusted based on the near-field codeword, the beam formed is called a near-field beam.

[0138] Step 2: The base station sends codeword information to the beam adjustment device.

[0139] 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.

[0140] Accordingly, the beam adjustment device receives the codeword information.

[0141] Step 3: The beam adjustment device generates an adjusted beam to be transmitted based on the codeword information.

[0142] Exemplarily, the beam adjustment device adjusts the phase of each electromagnetic unit according to the codeword information to adjust the beam to be transmitted, so that the adjusted beam to be transmitted can be focused in the direction of the terminal and the beam energy can be focused on the location of the terminal.

[0143] The following introduces the process of implementing beam adjustment in situation 2.

[0144] Step 1: Based on the azimuth angle between the terminal and the beam adjustment device, determine the codeword information corresponding to the terminal.

[0145] The codeword information includes a phase parameter corresponding to each electromagnetic unit of the beam adjustment device.

[0146] In one possible implementation, channel state information between a beam adjustment device and a terminal is determined based on an azimuth angle, where the channel state information is used to indicate a state and characteristics of a channel; and codeword information corresponding to the channel state information is determined as codeword information corresponding to the terminal.

[0147] Exemplarily, the base station presets a codebook for adjusting the beam to be transmitted, and the codebook contains multiple codeword information. One of the preset azimuth intervals corresponds to a sub-codebook in the codebook. For example, [α±θ] represents the preset azimuth interval.

[0148] After the beam adjustment device adjusts the beam to be transmitted based on the codebook, the beam can cover the area covered by the beam adjustment device.

[0149] It is understandable that due to the existence of measurement errors, such as measurement deviation of the azimuth angle, there is a certain error in the calculated azimuth angle compared with the actual situation, so the error is minimized by presetting the azimuth angle interval.

[0150] Based on the azimuth, determine the preset azimuth interval corresponding to the azimuth, that is, determine the corresponding sub-codebook. At different times, send each codeword information in the sub-codebook to the beam adjustment device in turn. The beam adjustment device adjusts the phase of each electromagnetic unit of the beam adjustment device based on each codeword information, thereby adjusting the beam to be transmitted and obtaining the adjusted beam to be transmitted. The adjusted beam to be transmitted is sent to the terminal. After the terminal receives the adjusted beam to be transmitted, it measures the channel state information between the beam adjustment device and the terminal corresponding to the codeword information, such as signal amplitude, phase, multipath delay, frequency deviation, etc., and reports the channel state information to the base station. After traversing all the codeword information in the sub-codebook, the base station processes the channel state information reported by the terminal, thereby determining the codeword information corresponding to the channel state information in the sub-codebook as the codeword information corresponding to the terminal.

[0151] It should be noted that, when the beam to be transmitted is adjusted based on the codeword information corresponding to the terminal and the beam is transmitted to the terminal, the beam can point to the direction where the terminal is located.

[0152] In this way, based on the channel state information between the beam adjustment device and the terminal, the codeword information corresponding to the channel state information is determined, so that the beam to be transmitted adjusted based on the codeword information can be finely focused on a specific direction, that is, the direction where the terminal is located, thereby improving the beam coverage performance.

[0153] In another possible implementation manner, codeword information corresponding to the terminal is determined based on the azimuth angle through beam training technology.

[0154] Exemplarily, the base station presets a codebook for adjusting the beam to be transmitted, the codebook includes a plurality of codeword information, and one of the preset azimuth angles corresponds to a sub-codebook in the codebook.

[0155] Based on the azimuth, determine the subcodebook corresponding to the azimuth. At different times, send each codeword information in the subcodebook to the beam adjustment device in turn. The beam adjustment device adjusts the phase of each electromagnetic unit of the beam adjustment device based on each codeword information, thereby adjusting the beam to be transmitted and obtaining the adjusted beam to be transmitted. The adjusted beam to be transmitted is sent to the terminal. After the terminal receives the adjusted beam to be transmitted, it measures the signal strength corresponding to the codeword information and reports the signal strength to the base station. After traversing all the codeword information in the subcodebook, the base station determines the codeword information corresponding to the largest signal strength as the codeword information corresponding to the terminal based on the signal strength reported by the terminal.

[0156] It should be noted that, when the beam to be transmitted is adjusted based on the codeword information corresponding to the terminal and the beam is transmitted to the terminal, the beam can point to the direction where the terminal is located.

[0157] In this way, based on the beam training technology, the codeword information corresponding to the terminal is determined, so that the beam to be transmitted adjusted based on the codeword information can be focused in a specific direction, that is, the direction of the terminal, thereby improving the beam coverage performance.

[0158] In addition, when the second area is a far field area, the codeword information corresponding to the terminal is determined based on the azimuth, which is called the far field codeword. After the phase of each electromagnetic unit of the beam adjustment device is adjusted based on the far field codeword, the beam formed is called the far field beam.

[0159] Compared with far-field beams, near-field beams can control the energy distribution of near-field beams based on the new dimension of distance due to the spherical wave model in the near-field area to achieve more precise beam steering. In other words, in the near-field area, the beam can be focused in a specific direction and the beam energy can be focused at a specific distance, so as to maximize the signal strength at the terminal location and improve the beam steering accuracy; in the far-field area, the beam can be focused in a specific direction, which can improve the beam coverage performance.

[0160] Step 2: The base station sends codeword information to the beam adjustment device.

[0161] 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.

[0162] Accordingly, the beam adjustment device receives the codeword information.

[0163] Step 3: The beam adjustment device generates an adjusted beam to be transmitted based on the codeword information.

[0164] Exemplarily, the beam adjustment device adjusts the phase of each electromagnetic unit according to the codeword information to adjust the beam to be transmitted so that the adjusted beam to be transmitted can be focused in the direction of the terminal.

[0165] Based on the above technical solution, the beam adjustment method provided in the present application can obtain the first area or the second area within the signal coverage range of the beam adjustment device where the terminal is located by acquiring the area information of the terminal. By determining different codeword information for different areas where the terminal is located, differentiated matching of codeword information in different areas can be achieved, thereby improving the accuracy of beam control, thereby meeting the communication needs of terminals located in different areas and improving user experience.

[0166] Based on this scheme, when the terminal is respectively located in the first area and the second area within the signal coverage range of the beam adjustment device, it is possible to adaptively determine the codeword information corresponding to the terminal, adopt different beam adjustment methods, and adjust the beam to be transmitted based on the codeword information to improve the coverage performance of the beam; when the terminal is located in the first area within the signal coverage range of the beam adjustment device, after adjusting the beam to be transmitted based on the codeword information corresponding to the terminal, the adjusted beam to be transmitted can be pointed in the direction of the terminal, and the beam energy can be focused on the location of the terminal, thereby improving the accuracy of beam control; when the terminal is located in the second area within the signal coverage range of the beam adjustment device, after adjusting the beam to be transmitted based on the codeword information corresponding to the terminal, the adjusted beam to be transmitted can be pointed in the direction of the terminal, thereby improving the coverage performance of the beam.
