Description

Technical Field

[0001] This application relates to the field of wireless communication security technology, specifically providing a 6G signaling-level shielding method and system based on intelligent reflector cooperative control. Background Technology

[0002] As sixth-generation mobile communication (6G) technology evolves towards terahertz communication, reconfigurable intelligent surfaces (RIS), and integrated communication and computing technologies, its network density, spectral efficiency, and transmission rate will experience a leap forward. Simultaneously, the need for precise and controllable management of wireless communication in specific sensitive areas is becoming increasingly urgent, aiming to prevent the misuse of communication tools and ensure information security and order.

[0003] Currently, the mobile communication jamming devices widely used in the aforementioned scenarios are primarily based on the traditional broadband noise interference principle. These devices attempt to overwhelm legitimate communication signals within the target frequency band at the physical layer by emitting broadband, high-power interference signals. However, with the iteration of communication technologies, especially 6G technology, these traditional jamming solutions have exposed the following critical problems that urgently need to be addressed:

[0004] Uncontrollable interference range: Omnidirectional radiation severely affects the normal communication links of operator base stations;

[0005] Low power efficiency: High-power transmission is often used to achieve shielding effect, which violates the restrictions on transmission power in the type approval of radio transmission equipment;

[0006] Difficult to adapt to 6G new air interface: 6G system adopts massive MIMO, beamforming and dynamic spectrum sharing, and traditional interference technology cannot achieve signaling-level precise shielding.

[0007] In the existing technology, some improvement solutions have emerged. For example, some related patent literature optimizes communication quality by predicting channel quality, but its focus is on communication enhancement rather than shielding. On the other hand, intelligent reflective surfaces (RIS), as an emerging technology, have been widely studied for enhancing signal coverage, but their application in the field of shielding is not yet perfect. Summary of the Invention

[0008] This application provides a 6G signaling-level shielding method and system based on intelligent reflective surface collaborative control, aiming to solve the problems of traditional shielding equipment affecting public base stations due to omnidirectional interference, facing compliance risks due to high-power transmission, and being unable to effectively counter the advanced physical layer mechanism of 6G due to outdated technical principles.

[0009] Firstly, a 6G signaling-level shielding method based on intelligent reflector cooperative control is provided, including:

[0010] S1, acquire sensing data of 6G terminal communication signals within the target area, and parse the signaling characteristics and spatiotemporal frequency domain parameters of the target terminal; the spatiotemporal frequency domain parameters include at least the orientation information of the target terminal relative to the intelligent reflector array;

[0011] S2, based on the signaling features and spatiotemporal frequency domain parameters, generate configuration parameters for controlling the intelligent reflector array, and generate a signaling-level shielding signal synchronized with the target signal;

[0012] S3, control the intelligent reflective surface array to work according to the configuration parameters, thereby directionally reflecting the signaling-level shielded signal to the target terminal, so that it cannot correctly parse the signaling.

[0013] Optionally, the above scheme may further include step S4: predicting the quality changes of the target channel based on channel state information, and accordingly adjusting the power or coding strategy of the signaling-level shielding signal in advance in step S2.

[0014] In the above scheme, optionally, the intelligent reflective surface array is a passive reflective surface, and its reflective units are composed of PIN diode arrays. The configuration parameters are used to dynamically adjust the reflection phase of each reflective unit.

[0015] Optionally, in the above scheme, the signaling-level shielding signal is a deception signal generated based on the 6G physical layer frame structure. Its modulation method and time slot structure are consistent with the legitimate signal, but it contains error bits in the key signaling fields.

[0016] Optionally, in step S3, the transmission power of the signaling-level shielding signal and the beam pointing of the intelligent reflector array are adjusted in real time to minimize the impact on non-target areas and base stations.

[0017] Secondly, a 6G signaling-level shielding system based on intelligent reflector cooperative control is provided to implement the above method, including:

[0018] The sensing and detection module is used to capture 6G signals in the target area and analyze them to obtain signaling characteristics;

[0019] The main control module is connected to the sensing and detection module and is used to generate configuration parameters for the intelligent reflective array and generation parameters for the signaling-level shielding signal based on the signaling characteristics.

[0020] A signal generation and transmission module, connected to the main control module, is used to generate the signaling-level shielding signal;

[0021] The intelligent reflective array, connected to the main control module and the signal generation and transmission module, is used to receive the configuration parameters and the signaling-level shielding signal, and to directionally reflect the signaling-level shielding signal to the target terminal.

[0022] Optionally, in the above scheme, the system further includes a compliance control module, used to automatically limit the transmission power, frequency band, and waveform modulation method of the signaling-level shielded signal within a preset compliance range.

[0023] Optionally, in the above scheme, the intelligent reflective surface array is a hybrid intelligent reflective surface, including a passive reflective unit and an active sensing unit.

[0024] Optionally, in the above scheme, the perception and detection module uses a neural network-based artificial intelligence algorithm to identify and classify the signaling in real time.

[0025] Compared with the prior art, this application has at least the following beneficial effects:

[0026] Based on further analysis and research into existing technical problems, this application recognizes that existing technologies suffer from issues such as traditional shielding equipment affecting public base stations due to omnidirectional interference, facing compliance risks due to high-power transmission, and being unable to effectively counter 6G advanced physical layer mechanisms due to outdated technical principles. By introducing a Smart Reflector (RIS) collaborative control mechanism and innovatively implementing signaling-level precise interference, a balance is achieved between shielding effectiveness, network friendliness, and policy compliance. Specifically:

[0027] By utilizing the beamforming capabilities of intelligent reflective arrays, shielded signal energy is directionally and precisely reflected to specific target terminals, fundamentally changing the omnidirectional radiation operating mode of traditional solutions. This achieves the technical effect of controllable spatial interference range, minimizing co-channel interference to non-target areas and operator base stations, and ensuring the normal operation of public communication networks.

[0028] This attack replaces traditional broadband noise suppression by generating deceptive interference signals that are synchronized with the target signal in time and frequency and injecting erroneous signals into key signaling fields. This signaling-level attack can cause target terminal access failure or link interruption at the protocol layer with lower transmit power, achieving ultra-high power efficiency and low absolute transmit power. This makes it easier to control system transmission parameters within the limits of national radio type approval, solving the compliance problems of traditional solutions.

[0029] By comprehensively analyzing the signaling characteristics and spatiotemporal frequency domain parameters (such as azimuth) of the target, and dynamically controlling the RIS (Radio Interception System) to generate deception signals, the shielding system acquires the ability to sense, adapt to, and counter 6G New Radio (NR) technologies. This method can effectively cope with beamforming of massive MIMO and track frequency changes in dynamic spectrum sharing, thereby achieving a stable and reliable shielding effect against 6G terminals using advanced technologies, overcoming the technical failure risks faced by traditional interference technologies.

[0030] In summary, the solution provided in this application ensures that the blocking objective is effectively achieved while also being friendly to public networks and complying with regulatory requirements. Attached Figure Description

[0031] Figure 1 This is a flowchart illustrating a 6G signaling-level shielding method based on intelligent reflective surface cooperative control, provided as an embodiment of this application. Detailed Implementation

[0032] 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.

[0033] In the description of this application, unless otherwise stated, the terms "including", "comprising", "having", etc., also mean "not limited to" (certain units, components, materials, steps, etc.).

[0034] The purpose of this application is to provide a 6G signaling-level shielding method and system based on intelligent reflective surface collaborative control, to solve the problems of traditional shielding devices affecting base station operation, low power efficiency, and inability to adapt to the 6G new radio interface. This application particularly emphasizes the compliance of signaling-level precise shielding with the requirements of the Ministry of Industry and Information Technology's wireless equipment type approval.

[0035] In one embodiment, a 6G signaling-level shielding method based on intelligent reflector cooperative control is provided, including:

[0036] S1, acquire sensing data of 6G terminal communication signals within the target area, and parse the signaling characteristics and spatiotemporal frequency domain parameters of the target terminal; the spatiotemporal frequency domain parameters include at least the orientation information of the target terminal relative to the intelligent reflector array;

[0037] S2, based on the signaling features and spatiotemporal frequency domain parameters, generate configuration parameters for controlling the intelligent reflector array, and generate a signaling-level shielding signal synchronized with the target signal;

[0038] S3, control the intelligent reflective surface array to work according to the configuration parameters, thereby directionally reflecting the signaling-level shielded signal to the target terminal, so that it cannot correctly parse the signaling.

[0039] In this embodiment, the 6G signaling-level shielding method based on intelligent reflector cooperative control provided in this application mainly includes the following three core steps in its workflow:

[0040] Step S1: Signal Sensing and Feature Analysis. The system continuously scans and receives 6GHz wireless signals using a sensing node array (which can be deployed independently or co-located with the intelligent reflector array) deployed around the target area. After capturing the raw signal, the sensing nodes first perform down-conversion, filtering, and digitization to obtain baseband sensing data. Subsequently, the sensing data is demodulated and analyzed using built-in signal analysis algorithms (e.g., based on matched filtering, correlation detection, or machine learning models) to extract the signaling features of the target terminal, such as random access preambles, demodulation reference signals, and control channel information in specific formats—signal units with terminal identification or protocol status. Simultaneously, combining the geometric position of the sensing node array with signal processing algorithms (e.g., direction of arrival estimation, time difference positioning), the spatiotemporal frequency domain parameters of the target terminal are further analyzed. These parameters include at least the azimuth and elevation angles of the target terminal relative to the intelligent reflector array, and may further include distance information, signal carrier frequency, bandwidth, and precise timing information of the signal frames.

[0041] Step S2: Cooperative Control Strategy and Shielding Signal Generation. The main control module (such as a high-performance FPGA or embedded processor) receives the signaling characteristics and spatiotemporal frequency domain parameters from Step S1. Based on this information, the main control module performs two calculations:

[0042] Generating Smart Reflector Configuration Parameters: Based on information such as the orientation of the target terminal, beamforming algorithms (such as phase-based precoding algorithms) are used to calculate the required bias voltage or control codeword for each reconfigurable reflective unit (e.g., composed of PIN diodes) in the smart reflector array. This set of configuration parameters enables the RIS to reflect and converge incident electromagnetic waves into a directional beam with its main lobe aligned with the target terminal.

[0043] Generate signaling-level jamming signal: Under the instruction of the main control module, the signal generation module synthesizes a special interference signal. This signal is not broadband noise, but a "deception signal" that strictly imitates the 6G physical layer frame structure and modulation method and maintains time-frequency synchronization with the target signal. The key is that, during the generation process, a preset error bit pattern or distortion sequence is implanted into key signaling fields (such as synchronization signal blocks, downlink control information, or specific reference signal sequences) within the legitimate signal frame. Furthermore, the power spectral density and transmission frequency band of the generated signal are monitored and limited in real time by a compliance control submodule to ensure that it always complies with the type approval requirements of the national radio management agency.

[0044] Step S3: Directional Reflection and Precise Shielding. The main control module sends the configuration parameters generated in step S2 to the control circuit (such as the FPGA driver unit) of the intelligent reflector array. Each reflector element on the intelligent reflector array synchronously adjusts its own electromagnetic characteristics (mainly the reflection phase) according to the received parameters, thereby physically reconstructing the reflected wavefront on its surface. At this time, the signaling-level shielding signal generated by the signal generation module and transmitted to the RIS via the feed source, after being reflected by the precisely configured RIS, has its propagation direction changed, its energy is highly concentrated, and it is directionally reflected to the spatial location of the target terminal determined in step S1. The antenna of the target terminal will simultaneously receive the signal from the legitimate base station and this directionally reflected shielding signal. Because the shielding signal contains errors in key signaling and may achieve a higher equivalent signal-to-noise ratio due to beamforming, the terminal may experience confusion or errors during demodulation and protocol parsing, ultimately failing to successfully access the network, maintain the connection, or correctly execute communication commands, thus achieving precise and covert shielding at the signaling level.

[0045] This application provides a 6G signaling-level shielding method and system based on intelligent reflector cooperative control. First, a spectrum sensing unit is used to detect the communication signals of 6G terminal devices within the target area in real time and identify their signaling characteristics. Next, the electromagnetic wave propagation environment is reconstructed using the reflective elements of the intelligent reflector (RIS), generating a precise beamforming pattern for the specific terminal. Finally, signaling-level interference technology is employed to transmit a shielded signal synchronized with legitimate signals but with optimized power, causing signaling parsing errors at the target terminal while ensuring no impact on the normal operation of the operator's base station. This application specifically employs a mechanism combining passive reflection and active sensing, solving the problem of excessive power in traditional shielders affecting the normal operation of base stations. Furthermore, through precise control of frequency, power, and modulation characteristics, it meets the Ministry of Industry and Information Technology's requirements for wireless equipment type approval.

[0046] This application has the following advantages:

[0047] (1) Precise shielding: Through signaling-level interference and RIS beamforming, it only affects the target terminal and does not interfere with the base station or other users.

[0048] (2) Low power consumption and compliance: The passive RIS reflection is adopted, which significantly reduces the overall power consumption, and the power and frequency band are strictly controlled to meet the requirements of the Ministry of Industry and Information Technology for model approval.

[0049] (3) Adapt to 6G new radio: Supports terahertz frequency band and dynamic spectrum sharing, and effectively copes with the complex 6G environment through AI-driven perception and prediction models.

[0050] (4) High system integration: It integrates sensing, control and shielding functions into one, which is convenient for deployment and management and is suitable for various scenarios such as examination rooms and confidential meetings.

[0051] In one embodiment, the method further includes step S4: predicting the quality changes of the target channel based on channel state information, and accordingly adjusting the power or coding strategy of the signaling-level shielding signal in advance in step S2.

[0052] In this embodiment, the system continuously collects channel state information from sensing nodes or intelligent reflective arrays (or, if it is a hybrid type, its active sensing unit). This information includes not only the target terminal's current channel measurement results (such as received signal strength, signal-to-noise ratio, multipath delay spread, Doppler shift, etc.), but also its historical change sequence and contextual data related to the terminal's movement trajectory and environmental scatterers.

[0053] The main control module inputs the collected channel state information data into a pre-trained channel quality prediction model. The output of the prediction model is the trend and key parameters of the target channel quality changes over a future period, such as the predicted rise and fall of the signal-to-noise ratio, the possible shift of the dominant beam direction, or the possible occurrence of deep fading. Based on the prediction results, the main control module performs forward-looking adjustments in step S2 (cooperative control strategy and shielding signal generation), rather than simply reacting to the current state: if it predicts that the target channel path loss will increase or the signal-to-noise ratio will decrease, the system can gradually and slightly increase the transmission power of the shielding signal in advance. If it predicts that the channel will enter a short period of deep fading, the system can switch to a more robust but lower-rate interference signal coding scheme in advance to ensure that the interference signal can be reliably received by the terminal during this critical period, thereby preventing the terminal from successfully decoding the legitimate signal during the fading gap.

[0054] In this embodiment, the core of this application lies in achieving precise shielding of specific 6G terminals through intelligent reflector (RIS) collaborative control and signaling-level interference technology, while minimizing interference to the base station. The overall system consists of a sensing and detection module, a main control module, an intelligent reflector array, and a signal generation and transmission module.

[0055] Signal perception and signaling parsing: The system captures 6G signals in the target area through sensing nodes, extracts their features (such as pilot sequences, reference signals, etc.), and uses AI algorithms (such as the BFGMAQENN model) to identify the signaling patterns of the target terminal.

[0056] RIS Reflection Beamforming: Based on signaling analysis results, the main control module controls the bias voltage of the RIS reflection unit (such as a PIN diode) via FPGA to dynamically adjust the phase and amplitude of the reflected beam, forming a directional beam targeting the terminal. Passive RIS is preferred to reduce power consumption and cost.

[0057] Signaling-level shielding signal generation: The signal generation module generates a shielding signal that is synchronized with the 6G standard signaling. This signal injects errors into key fields of the physical layer frame structure (such as synchronization signals or system information blocks), causing the terminal to be unable to access the network or maintain the connection.

[0058] Compliance-compliant power control: The system has a built-in compliance control module that monitors the transmission power and frequency band in real time to ensure that it always complies with the Ministry of Industry and Information Technology's radio type approval requirements. For example, within a specific frequency band, the power density is controlled below -40 dBm / MHz.

[0059] Dynamic channel adaptation: The system further utilizes channel quality prediction technology to predict channel changes through a spatiotemporal graph neural network and adjust the shielding strategy in advance to cope with the high dynamic characteristics of 6G channels.

[0060] In one embodiment, the intelligent reflective surface array is a passive reflective surface, and its reflective units are composed of a PIN diode array. The configuration parameters are used to dynamically adjust the reflection phase of each reflective unit.

[0061] In this embodiment, the intelligent reflector (RIS) array is a passive reflector. Its core consists of a large number of regularly arranged reflective units, each with a PIN diode as its core component. By applying specific configuration parameters (typically a bias voltage sequence applied to each diode) to the array via an external controller (such as an FPGA), the reflection phase of each reflective unit to the incident electromagnetic wave can be dynamically and precisely controlled. This programmable phase control is the physical basis for the intelligent reflector's ability to reconstruct the electromagnetic wavefront and achieve beamforming directional reflection. This passive structure eliminates the need for expensive RF power amplifier chains, offering significant advantages such as low power consumption, controllable cost, and ease of large-scale deployment.

[0062] In one embodiment, the signaling-level shielding signal is a deception signal generated based on the 6G physical layer frame structure. Its modulation method and time slot structure are consistent with the legitimate signal, but it contains error bits in the key signaling fields.

[0063] In this embodiment, the signaling-level shielding signal is not traditional broadband noise, but a highly simulated spoofing signal generated based on the 6G standard physical layer frame structure. The modulation method (such as QPSK, OFDM), time slot structure, and frame timing of this signal are synchronized with the legitimate base station signals in the target area, giving it a high degree of similarity and compatibility in physical layer parameters. Its core interference mechanism lies in precisely implanting pre-designed erroneous bit sequences or distorted modulation symbols into key signaling fields (such as synchronization signal blocks, system information broadcasts, or random access responses) within the completely replicated frame structure. When this spoofing signal is received by the target terminal along with the legitimate signal, the terminal will experience decoding failure, state machine chaos, or access rejection during protocol stack parsing due to these errors in key information, thereby achieving a precise shielding effect that causes communication link failure from the protocol layer.

[0064] In one embodiment, in step S3, the transmission power of the signaling-level shielding signal and the beam pointing of the intelligent reflector array are adjusted in real time to minimize the impact on non-target areas and base stations.

[0065] In one embodiment, when performing step S3, the system forms a dynamic closed loop. The main control module continuously fine-tunes the transmission power of the signaling-level shielding signal and the beam pointing angle of the intelligent reflector array based on real-time monitoring of the target terminal's signal strength and location feedback, as well as a preset compliant power threshold. This dynamic adjustment mechanism ensures that the shielding energy is always precisely focused on the moving target with the necessary minimum intensity, thereby actively suppressing signal leakage in both spatial and power dimensions, effectively minimizing interference to non-target areas and operator base stations.

[0066] In one embodiment, the solution of this application is illustrated by taking the target area as the examination room as an example.

[0067] Hardware Deployment: Deploy sensing nodes and RIS panels around the target area (e.g., the examination room). The RIS is preferably a hybrid structure to balance sensing and shielding functions. Each RIS unit consists of an outer metal patch, a middle copper plate, and an inner control circuit (e.g., an FPGA).

[0068] Signal detection and signaling analysis: The sensing node continuously scans 6G uplink and downlink signals and uses an AI model based on BFGMAQENN to identify the signaling characteristics of target terminals (such as cheating devices) in real time, including random access prefixes and demodulation reference signals.

[0069] RIS Configuration and Beamforming: Based on the signaling parsing results, the main control module calculates the RIS reflection parameters. By adjusting the bias voltage of the PIN diodes, the phase of the reflected beam is reconstructed, ensuring that the main lobe of the beam is precisely pointed to the target terminal.

[0070] Shielded signal transmission and power control: The signal generation module generates a shielded signal synchronized with the 6G frame structure and reflects it to the target terminal via RIS. The compliance control module dynamically monitors the transmission power to ensure compliance with the Ministry of Industry and Information Technology's regulations. For example, within 6G candidate frequency bands (such as 7-8GHz), the power spectral density is consistently below the approved limit.

[0071] Dynamic optimization: The system periodically collects channel state information and uses prediction methods to predict changes in channel quality, dynamically adjusting the power and beam shape of the shielded signal to cope with terminal movement or environmental changes.

[0072] In a preferred embodiment, the system can be further integrated with novel superlattice shielding materials to improve the shielding effectiveness and reliability of RIS.

[0073] In one embodiment, a 6G signaling-level shielding system based on intelligent reflective surface cooperative control is also provided to implement the method provided in the above embodiment, including:

[0074] The sensing and detection module is used to capture 6G signals in the target area and analyze them to obtain signaling characteristics;

[0075] The main control module is connected to the sensing and detection module and is used to generate configuration parameters for the intelligent reflective array and generation parameters for the signaling-level shielding signal based on the signaling characteristics.

[0076] A signal generation and transmission module, connected to the main control module, is used to generate the signaling-level shielding signal;

[0077] The intelligent reflective array, connected to the main control module and the signal generation and transmission module, is used to receive the configuration parameters and the signaling-level shielding signal, and to directionally reflect the signaling-level shielding signal to the target terminal.

[0078] In this embodiment, the 6G signaling-level shielding system based on intelligent reflective surface cooperative control provided in this application has the following hardware and functional module configuration:

[0079] The system mainly includes a sensing and detection module, a main control module, a signal generation and transmission module, and an intelligent reflective array. The modules are connected and coordinate via wired or wireless control links.

[0080] The sensing and detection module is deployed in the target area and is responsible for capturing the raw 6G signals in the air and converting them into digital baseband data. Then, the signal processing algorithm is used to analyze the signaling features contained therein.

[0081] The main control module, as the computing and decision-making center, receives the above signaling characteristics and runs the core algorithm to generate two key parameters: one is the configuration parameter used to control the beam shape of the intelligent reflector, and the other is the generation parameter used to define the details of the shielding signal.

[0082] The signal generation and transmission module synthesizes a precise signaling-level shielding signal using the radio frequency link based on the generation parameters and feeds it to the intelligent reflector array. After receiving the configuration parameters, the intelligent reflector array dynamically adjusts the electromagnetic response of all its reflector units, thereby directionally reflecting the received shielding signal to the target terminal and completing precise shielding.

[0083] In one embodiment, the system further includes a compliance control module for automatically limiting the transmission power, frequency band, and waveform modulation method of the signaling-level shielded signal within a preset compliance range.

[0084] In this embodiment, the system integrates a compliance control module (which can be embedded software within the main control module or a standalone hardware unit). This module pre-stores or receives in real-time the approval requirements of the national radio management agency for transmitting equipment (such as power spectral density limits for each frequency band, out-of-band transmission templates, occupied bandwidth, etc.), and uses these as inviolable hard constraints. It performs real-time comparison and feedback control throughout the entire signal generation and transmission process. Once it detects that the transmission power, frequency band, or waveform modulation method tends to exceed the preset compliance range, it immediately forces adjustments to the relevant parameters to ensure that the radiation of the system is strictly legal and compliant at all times.

[0085] In one embodiment, the smart reflective surface array is a hybrid smart reflective surface, comprising a passive reflective unit and an active sensing unit.

[0086] In this embodiment, the intelligent reflective array adopts a hybrid structural design. Most of its units are passive reflective units (such as those based on PIN diodes), responsible for efficiently reflecting shielded signals in a low-power manner; simultaneously, a small number of active sensing units (such as miniature RF front-ends integrating low-noise amplifiers and down-conversion links) are distributed and embedded. These active units can collect environmental wireless signals and channel information in situ and in real time without interrupting the reflection function, providing the system with richer and more accurate sensing data, thereby achieving a better balance between system complexity and sensing-control performance.

[0087] In one embodiment, the sensing and detection module uses a neural network-based artificial intelligence algorithm to identify and classify signaling in real time.

[0088] In this embodiment, the core signal analysis capability of the sensing and detection module is driven by a neural network-based artificial intelligence algorithm. This algorithm, trained on massive amounts of 6G signaling data, is capable of high-speed feature extraction, real-time identification, and automatic classification of complex signals captured in real time. This allows for rapid and accurate identification of specific signaling patterns (such as random access requests, specific reference signal sequences, etc.) of the target terminal in complex electromagnetic environments, providing reliable input for subsequent precise control.

[0089] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
