报告内容：
This talk highlights reconfigurable intelligent surfaces (RISs) as a transformative 6G technology for optimizing signal distribution and controlling wireless transmissions. Key topics include their implementations, functionalities, and mathematical modeling. Focusing on diffusion functionality, RISs as randomly reconfigurable surfaces (RRSs) with time-varying phase shifts are discussed for enhanced communication. Cascaded RIS networks are explored, demonstrating superior coverage and signal quality compared to single RIS setups.
Zero-energy RISs (zeRIS), powered entirely by harvested energy, are introduced for sustainable communication. Light-emitting RISs (LeRIS), integrating LEDs for precise user localization, and UAV-mounted RISs for IoT data collection are also presented. The latter leverages UAV mobility, energy-aware design, and a novel medium access control protocol to improve IoT system throughput in 6G networks.
