[0033] RIS is a new wireless communication technology that intelligently regulates the propagation of wireless signals through a large number of passive reflecting elements. These reflecting elements can adjust the phase, amplitude, and other parameters of the reflected signal. In theory, the RIS panel can create multiple communication channel links. For example, in a complex indoor communication scenario, the RIS can reflect the signal to an area that the signal cannot directly reach. By reasonably configuring the reflecting elements, just like adjusting the angle of a mirror, the signal can be directed to different receiving ends, thereby creating multiple links.

[0034] Multi-hop communication: Multi-hop communication refers to the process of signal transmission from the source node to the destination node through multiple intermediate nodes. The RIS panel itself mainly reflects the signal and is not a traditional signal forwarding node. However, it can assist in multi-hop communication. For example, there is an obstacle between two communication nodes, and the direct communication link is blocked. By deploying an RIS panel at a suitable position, the signal can be reflected to an intermediate relay node, which then forwards the signal to the destination node, thereby realizing a multi-hop communication function.

[0035] In terms of multi-path communication: RIS panels can create different reflection paths by adjusting the reflection units. In a multi-path fading channel environment, the superposition of signals from different paths can produce complex fading phenomena. RIS can be designed to enhance the signals of certain paths while weakening the signals of other paths to optimize overall communication performance. For example, in an outdoor wireless communication scenario, part of the signal from the base station directly reaches the mobile terminal, and another part of the signal reaches the mobile terminal after being reflected by the RIS panel, forming a multi-path communication. And by dynamically adjusting the parameters of the RIS panel, the combination of these multi-path signals can be optimized to improve communication quality. Therefore, in theory and certain application scenarios, RIS panels can create multiple communication channel links and support multi-hop or multi-path communication.

[0036] In the specific embodiment, based on the above analysis, an RIS-based intelligent multi-link communication networking system is constructed to overcome the defects of existing communication technologies in the face of physical obstacles, signal attenuation, and poor communication quality. The specific structure is as follows, including:

[0037] A central electromagnetic interface controller, an information acquisition module, an RIS intelligent communication panel, a communication link module, and a terminal, the information acquisition module is signal connected with the RIS intelligent communication panel; the central electromagnetic interface controller is signal connected with the information acquisition module, the RIS intelligent communication panel, and the communication link module; the RIS intelligent communication panel is signal connected with the terminal through the communication link module.

[0038] This embodiment is equipped with multiple RIS intelligent communication panels, which are distributed at key nodes in the communication area. According to the topography, building distribution, and communication demand of the communication area, the multiple RIS intelligent communication panels are reasonably selected and laid out to ensure that effective signal coverage and transmission links are formed between the panels. They are set at locations such as the top of a building or a mountain to achieve wide-area coverage and signal relay transmission. Each RIS intelligent communication panel is composed of a large number of independently controllable communication units arranged closely. These communication units have high-precision phase and amplitude adjustment capabilities and are signal connected with the central electromagnetic interface controller for cooperative work. The central electromagnetic interface controller, as the core control unit of the system, collects state information of the communication link in real time through the information acquisition module, including signal strength, noise level, and transmission delay, etc. Combined with environmental monitoring data, including the location and material of obstacles, the phase and amplitude of each unit communication channel are determined. The determination method is a known calculation method in the prior art for determining the phase and amplitude of each unit communication channel.

[0039] Specifically, the communication link module is matched with the RIS intelligent communication panel, the output end of the communication link module is connected with the input end of the RIS intelligent communication panel, and the output end of the RIS intelligent communication panel is connected with the input end of the communication link module. The communication link module comprises a receiving antenna, a signal input end, an input signal dividing module, a radio frequency source and a transmitting antenna, which are connected in sequence, the input signal dividing module is also directly connected with the input end of the RIS intelligent communication panel, and the transmitting antenna is connected with the output end of the RIS intelligent communication panel. The communication link module comprises a plurality of communication link modules, the output end of a previous communication link module is connected with the input end of a next communication link module. The transmitting antenna of the previous communication link module is connected with the receiving antenna of the next communication link module. The terminal is connected with the transmitting antenna of the communication link module.

[0040] When the communication link is a single-hop link, the signal is received by the receiving antenna of the communication link module, sequentially transmitted through the receiving antenna, the signal input end, the input signal dividing module and the radio frequency source, and directly connected with the input end of the RIS intelligent communication panel through the input signal dividing module, and then transmitted to the communication unit in the RIS intelligent communication panel, and then transmitted to the terminal through the communication unit and the transmitting antenna of the communication link module.

[0041] When the communication link is a multi-hop link, the signal is received by the receiving antenna of the communication link module, sequentially transmitted through the receiving antenna, the signal input end, the input signal dividing module and the radio frequency source, and directly connected with the input end of the RIS intelligent communication panel through the input signal dividing module, and then transmitted to the communication unit in the RIS intelligent communication panel, and then transmitted to the terminal through the communication unit and the transmitting antenna of the communication link module.

[0042] When the system is running, the RIS panel can create multiple communication channel links by virtue of its unique reconfigurable characteristics, and these links can be flexibly combined and switched according to actual conditions, supporting multi-hop or multi-path communication mode. For example, when encountering large buildings, the signal can be reflected, refracted and jumped between multiple RIS panels, forming multiple detour communication paths, thereby effectively overcoming signal attenuation caused by physical obstacles.
