[0044] The target grid in the beam coverage area of ​​the reconfigurable smart surface RIS is determined based on the terminal location information of the uplink hotspot terminal; the target grid includes at least one uplink hotspot terminal.

[0045] The scanning state of the beam corresponding to the target grid is controlled based on the number of uplink hotspot terminals in the target grid.

[0046] Eighthly, this application also provides a computer device, which includes a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to perform the following steps:

[0047] A dedicated BSR is sent to the base station.

[0050] In a tenth aspect, this application also provides a computer program product comprising a computer program that, when executed by a processor, performs the following steps:

[0052] The aforementioned beam scanning methods, apparatus, communication equipment, and storage media, when deployed in a system with a Reliable Surface Arrangement (RIS), can lead to resource waste if the RIS continuously performs beam scanning. In this application, the base station identifies uplink hotspot terminals based on the Dedicated Buffer Status Reports (BSRs) reported by each terminal. Since these hotspot terminals correspond to large uplink data transmission volumes, the target grid within the beam coverage area of ​​the reconfigurable smart surface RIS is determined using the location information of the uplink hotspot terminals. This aims to selectively identify areas requiring beam control (i.e., target grids) based on the uplink data transmission volume, eliminating the need to analyze and control every single grid within the RIS's beam coverage area. Subsequently, the base station analyzes the number of uplink hotspot terminals within each target grid and controls the scanning state of the beam corresponding to that target grid based on this number. This ensures that the scanning state of the beam corresponding to the target grid matches the amount of data that the terminals within that target grid need to upload, reducing beam resource waste.

[0064] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0065] like Figure 1 As shown, the beam control method provided in this embodiment is applied to... Figure 1 The system architecture shown may include terminal device 110, base station 120, and reconfigurable intelligent surfaces (RIS) 130. Terminal device 110 may include various electronic devices such as smartphones, tablets, laptops, and desktop computers. The main function of base station 120 is to provide wireless coverage, that is, to realize wireless signal transmission between wired communication networks and wireless terminals. Reconfigurable intelligent surfaces 130 communicate with base station 120.

[0066] Each base station 120 can contain one or more sectors, depending on the connected antennas. The coverage area of ​​a base station sector can range from several hundred to tens of kilometers. The coverage area of ​​a base station sector is the signal coverage area of ​​the base station. In densely populated areas, the coverage area is usually controlled to avoid interference with adjacent base stations 120. The base station's baseband and radio frequency (RF) processing capabilities determine that its physical structure consists of two main parts: a baseband module and an RF module. The baseband module primarily performs functions such as baseband modulation and demodulation, radio resource allocation, call processing, power control, and soft handover. The RF module primarily performs functions such as conversion between the air RF channel and the baseband digital channel, as well as RF channel amplification and transmission / reception.

[0067] Codeable smart surfaces 130 are an emerging type of man-made material device. Taking RIS as an example, RIS can dynamically / semi-statically change its own electromagnetic properties, affecting the reflection / refraction behavior of electromagnetic waves incident on RIS. By manipulating the reflected / refractive waves of electromagnetic waves, RIS can achieve functions such as beam scanning / beamforming.

[0068] The working principle and device structure of a RIS (Reflection and Refraction System) are as follows: A RIS consists of a front-end artificial surface and a back-end control module. The front-end artificial surface is composed of densely arranged artificial device units. The device characteristics of each unit are affected by the control signal / bias voltage. Different control signals / bias voltages correspond to different reflection / refractive coefficients. Changes in the reflection / refractive coefficient affect the phase and / or intensity of the reflected / refractive signal. Microscopically, each device unit results in an independent reflected / refractive signal, and macroscopically, these signals are superimposed to achieve the manipulation of electromagnetic waves. The control signal / bias voltage is provided by the back-end control module. There are two ways to implement a RIS device: one is a RIS device composed of purely passive units; the other is a RIS device that combines active and passive units, where most units in the RIS unit array are passive units, and a small number are active units. Passive units are the aforementioned novel device units. Each passive unit contains a controllable device (e.g., a PIN diode, a variable capacitor, etc.), and the state of the controllable device is controlled by the RIS device's control module. The state of the controllable device corresponds to different electromagnetic characteristics of the passive unit, such as the energy amplitude, phase, and polarization direction of the wireless signal. Active units include radio frequency link units, capable of receiving or transmitting radio frequency signals, processing wireless signals, or transmitting wireless signals according to base station instructions or protocol rules. Active units are more expensive and consume more power than passive units, but channel measurement results based on active units are more accurate and simpler than those based on passive units. In hybrid RIS devices, to balance cost and channel measurement methods, the active units are a small number and sparsely distributed.

[0069] RIS (Radio Router Support) can be used to enhance hotspot traffic or fill coverage holes. Future wireless services will include high-volume data services (such as AR / VR, high-definition video, etc.) or other services with high requirements for wireless channels. For ease of explanation, this embodiment refers to such high-requirement services as hotspot services, their users as hotspot users, and their terminals as hotspot terminals. A feasible solution to address the hotspot needs of hotspot users is to dynamically increase the available beams reaching them; the serving cell dynamically activates auxiliary equipment (such as panels, RIS) to increase the available beams for hotspot users and meet their service requirements. Obstacles within the cell's coverage area cause coverage holes, resulting in weak wireless signal strength and affecting communication quality; this phenomenon is more common in high-frequency / millimeter-wave bands. RIS is a base station-independent device that can be deployed far from the base station, providing communication services to coverage hole areas by forwarding / reflecting base station signals. Through reasonable node deployment, RIS avoids being blocked by obstructions, ensuring good signal coverage.

[0070] In one embodiment, such as Figure 2 As shown, a beam control method is provided, which is applied to... Figure 1 Taking base station 120 as an example, the explanation includes the following steps:

[0071] S201: Based on the Dedicated Buffer Status Report (BSR) submitted by each terminal, determine the uplink hotspot terminals.

[0072] When a terminal needs to send uplink data, it first sends a Scheduling Request (RS) to the base station on the allocated uplink resources. Upon receiving the RS, the base station allocates an uplink grant (UL grant) to the terminal. Then, the terminal sends a dedicated Backend Request (BSR) to the base station on the uplink grant. After receiving the dedicated BSR, the base station obtains the amount of uplink data the terminal needs to send based on the BSR and performs data scheduling according to this data amount and the priority of the uplink service. Therefore, the dedicated BSR indicates how much data the terminal's uplink buffer needs to send, enabling the base station to allocate uplink resources to the terminal so that the terminal can send uplink data to the base station using those resources.

[0073] It is understandable that an uplink hotspot terminal refers to a hotspot terminal where the amount of uplink data exceeds a preset data volume threshold.

[0074] S202, determine the target grid in the beam coverage area of ​​the reconfigurable smart surface RIS based on the terminal location information of the uplink hotspot terminal.

[0075] Optionally, the terminal may be equipped with a positioning module. The positioning module sends out wireless commands and uploads them via a satellite positioning system, which are then obtained by the base station. The uploaded signal may include the strength of the terminal's wireless signal, enabling the base station to obtain the location information of terminals within its communication coverage area, as well as the signal strength of each terminal.

[0076] It is understandable that signal-limited areas may exist within the communication coverage area of ​​a base station due to obstacles and other factors. Determining these signal-limited areas involves: acquiring the location information of communication terminals within the base station's coverage area, and acquiring the signal strength of these terminals. Based on the location information of communication terminals with signal strengths below a set threshold, the location information of the signal-limited areas can be obtained. Within the signal-limited areas, multiple reconfigurable smart surfaces (RIS) can be configured, each forming a specific RIS beam coverage area. Optionally, the base station adjusts its beam direction towards the RIS, the RIS activates and performs beam scanning, thereby determining the RIS beam coverage area.

[0077] Furthermore, each RIS can be numbered to form a RIS Beam ID, with each RIS Beam ID corresponding to a RIS beam coverage area. The beam coverage area of ​​each RIS is then gridded and numbered sequentially, and the RIS Beam ID is mapped to the RIS Beam Related Grid ID. Subsequently, the RIS reports the mapping relationship between the RIS Beam ID and the RIS Beam Related Grid ID, as well as the range and location information of each RIS Beam Related Grid, to the base station. Optionally, the RIS Beam Related Grid IDs corresponding to each RIS can be ordered in a consecutive numbering manner.

[0078] For example, such as Figure 3 As shown, the RIS beam IDs include RIS beam ID1 and RIS beam ID2. The RIS beam associated grid IDs corresponding to RIS beam ID1 are numbered 1, 2, 5, and 6; the RIS beam associated grid IDs corresponding to RIS beam ID2 are numbered 3, 4, 7, and 8.

[0079] In this embodiment, the target grid includes at least one uplink hotspot terminal, that is, the grid containing the uplink hotspot terminal is the target grid.

[0080] S203 controls the scanning state of the beam corresponding to the target grid based on the number of uplink hotspot terminals in the target grid.

[0081] Understandably, the more uplink hotspot terminals there are in the target grid, the more uplink data the target grid needs to upload. In this case, the scanning state of the beam corresponding to the target grid needs to be controlled to a state that assists in enhancing signal transmission, such as enabling (or activating) the RIS (Resonance Information System). Conversely, the fewer uplink hotspot terminals there are in the target grid, the less uplink data the target grid needs to upload. In this case, the scanning state of the beam corresponding to the target grid can be controlled to a state that does not require assisting in enhancing signal transmission, such as disabling the RIS.

[0082] In the aforementioned beam control method, if the RIS continuously scans its beam after deployment in the system, it will result in resource waste. However, in this application, the base station determines uplink hotspot terminals based on the dedicated buffer status reports (BSRs) reported by each terminal. It is known that the uplink hotspot terminals correspond to a large amount of uplink data transmission. Therefore, the target grid in the beam coverage area of ​​the reconfigurable smart surface RIS is determined by using the location information of the uplink hotspot terminals. The purpose is to determine the area (i.e., the target grid) that needs beam control based on the uplink data transmission volume, without having to analyze and control every grid in the beam coverage area of ​​the RIS. Then, the base station analyzes the number of uplink hotspot terminals in each target grid and controls the scanning state of the beam corresponding to the target grid based on the number of uplink hotspot terminals in the target grid. This ensures that the scanning state of the beam corresponding to the target grid matches the amount of data that the terminals in the target grid need to upload, reducing the waste of beam resources.

[0083] like Figure 4 As shown, this embodiment provides an optional method for determining uplink hotspot terminals based on the dedicated buffer status report (BSR) reported by each terminal, that is, a method for refining S202. The specific implementation process may include:

[0084] S401, obtain the terminal's logical channel group (LCG) domain information and time domain information from the dedicated BSR.

[0085] The LCG field indicates whether the terminal receives data from logical channel group 1. If the terminal receives the data, the value of this field is Y, and the offset between the desired receiving time and the current time is written into the LCG offset. If the terminal does not want to receive the data, the value of LCG is N, and the LCG offset is set to empty.

[0086] Optionally, the LCG domain information may also include a buffer size index, which represents the total amount of data across all logical channels of the LCG, expressed in bytes. The time domain information describes each subframe uploaded by the terminal.

[0087] S402, determine the uplink hotspot terminal based on LCG domain information and time domain information.

[0088] Specifically, if the LCG domain information and time domain information meet preset conditions, the corresponding terminal is identified as an uplink hotspot terminal; wherein, the preset conditions include that the dedicated BSR reported by the terminal in multiple consecutive subframes includes at least one LCG whose buffer size value index is not less than a first threshold.

[0089] For example, if the terminal is an uplink hotspot terminal, its corresponding collider computation grid LCG domain information and time domain information must meet preset conditions, namely conditions (a) and (b). Condition (a) describes the LCG domain: at least one LCG in the dedicated BSRs reported within a subframe has a Buffer Size Index greater than or equal to X; condition (b) describes the time domain: condition (a) is met for Y consecutive subframes. X is the first threshold.

[0090] Conversely, if the terminal is not an uplink hotspot terminal, then its corresponding collider computation grid LCG domain information and time domain information must simultaneously satisfy conditions (c) and (d). Among them, condition (c) describes the LCG domain: the Buffer Size Index corresponding to all LCGs in the Dedicated BSR reported within one subframe is less than X; condition (d) describes the time domain: condition (c) is satisfied for Y consecutive subframes.

[0091] For example, if a terminal reports a Buffer Size Index of 190 for LCG 0 and a Buffer Size Index of 210 for LCG 1 in five consecutive subframes, then the terminal is determined to be an uplink hotspot terminal.

[0092] In this embodiment, the uplink hotspot terminal is determined by two dimensions: the LCG domain and the time domain, which improves the accuracy of the uplink hotspot terminal determination.

[0093] like Figure 5 As shown, this embodiment provides an optional method for controlling the scanning state of the beam corresponding to the target grid based on the number of uplink hotspot terminals in the target grid, that is, a method for refining S203. The specific implementation process may include:

[0094] S501, determine the region type of each target grid based on the relationship between the number of uplink hotspot terminals in the target grid and the second threshold.

[0095] Specifically, if the number of uplink hotspot terminals in the target grid is greater than or equal to the second threshold, the region type of the target grid is determined to be an uplink hotspot region; if the number of uplink hotspot terminals in the target grid is less than the second threshold, the region type of the target grid is determined to be a non-uplink hotspot region.

[0096] For example, if there are 6 uplink hotspot terminals in RIS Beam Related Grid ID 4, then the area is determined to be an uplink hotspot area. If the number of uplink hotspot terminals in RIS Beam Related Grid ID 4 decreases to 5 (less than 6), then the area is determined to be a non-uplink hotspot area.

[0097] S502 controls the scanning state of the beam corresponding to each target grid according to the region type of each target grid.

[0098] Specifically, the beam coverage area of ​​the RIS is determined based on the sector signal strength of the base station; the beam coverage area is then gridded, and the correspondence between the grid identifier and the RIS beam identifier is determined.

[0099] It is understandable that signal strength can be tested in the base station sector of the base station through the terminal, and the base station sector can also be gridded. For any grid, if the average signal strength received by the communication terminal is lower than the set threshold for a certain period of time, it is determined that a RIS needs to be established in the grid. After the RIS is established in the area, the beam coverage area of ​​the RIS is determined according to the location information of the established RIS and the preset coverage range corresponding to the RIS.

[0100] Specifically, when the target grid's region type is an uplink hotspot region, the corresponding RIS beam for the target grid is determined based on the correspondence between the grid identifier and the RIS beam identifier, and the RIS beam is activated for scanning; when the target grid's region type is not an uplink hotspot region, the RIS beam is turned off.

[0101] In this embodiment, the uplink hotspot area is determined based on the number of uplink hotspot terminals. The base station controls the opening and closing of the RIS beam according to the uplink hotspot area determination result, thereby realizing on-demand scanning of the RIS beam and reducing resource consumption.

[0102] In one embodiment, such as Figure 6 As shown, a beam control method is provided, which is applied to... Figure 1 Taking terminal 110 as an example, the explanation includes the following steps:

[0103] S601, send a dedicated BSR to the base station. The dedicated BSR is used to instruct the base station to determine the uplink hotspot terminals according to the dedicated BSR, determine the target grid in the beam coverage area of ​​the RIS according to the terminal location information of the uplink hotspot terminals, and control the scanning state of the beam corresponding to the target grid according to the number of uplink hotspot terminals in the target grid.

[0104] In the above beam control method, when a terminal has a data transmission request, it only needs to send a dedicated BSR to the base station. The base station can then determine the uplink hotspot terminals based on the terminal's data transmission request and the dedicated BSR, and determine the target grid in the beam coverage area of ​​the RIS. Furthermore, based on the number of uplink hotspot terminals in the target grid, the base station controls the scanning state of the beam corresponding to the target grid, thereby configuring the beam scanning state for the data volume of the uplink terminals in each terminal and reducing the waste of beam resources.

[0105] For example, based on the above embodiments, this embodiment provides an optional example of a beam scanning method, applied to a base station, a terminal, and a RIS. For example... Figure 7 As shown, the specific implementation process includes:

[0106] S701, the terminal sends a dedicated BSR to the base station.

[0107] S702, the base station determines uplink hotspot terminals based on the dedicated buffer status report (BSR) reported by each terminal.

[0108] S703, determine the target grid within the beam coverage area of ​​the reconfigurable smart surface RIS based on the terminal location information of the uplink hotspot terminals. The target grid includes at least one uplink hotspot terminal.

[0109] S704, if the number of uplink hotspot terminals in the target grid is greater than or equal to the second threshold, determine the region type of the target grid as an uplink hotspot region.

[0110] S705, if the number of uplink hotspot terminals in the target grid is less than the second threshold, the region type of the target grid is determined to be a non-uplink hotspot region.

[0111] S706, when the target grid's region type is an uplink hotspot region, determines the RIS beam corresponding to the target grid based on the correspondence between the grid identifier and the RIS beam identifier, and sends an activation command to the RIS to switch the RIS to an active state for beam scanning.

[0112] S707, when the target grid's region type is a non-uplink hotspot region, sends a shutdown command to the RIS to switch the RIS to a shutdown state.

[0113] The specific processes of S701-S707 described above can be found in the description of the above method embodiments. Their implementation principles and technical effects are similar, and will not be repeated here.

[0114] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the above embodiments may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0115] Based on the same inventive concept, this application also provides a beam control device for implementing the beam control method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations in one or more beam control device embodiments provided below can be found in the limitations of the beam control method described above, and will not be repeated here.

[0116] In one embodiment, such as Figure 8 As shown, a beam scanning device 1 is provided, comprising: a first determining module 11, a second determining module 12, and a state control module 13, wherein:

[0117] The first determining module 11 is used to determine the uplink hotspot terminals based on the dedicated buffer status report (BSR) reported by each terminal.
