Abstract: The forthcoming sixth-generation (6G) wireless networks are expected to support unprecedented levels of efficiency and intelligence, motivating a fundamental shift from environment-unaware to environment-aware network operation. In this talk, we present a novel scatterer-based framework for channel map modeling, which exploits the physical structure of wireless propagation to represent high-dimensional channel information using a small set of physically meaningful scatterer parameters. The complete channel map is reconstructed by estimating these parameters from channel measurements collected at selected locations. To improve scalability, we further introduce the concept of virtual scatterers, which flexibly merge or split physical scatterers to balance reconstruction accuracy and computational complexity. Using channel gain maps as a case study, ray tracing simulations show that the proposed approach significantly outperforms existing model-based and model-free methods in reconstruction accuracy under the same channel measurement overhead.
