Special Session 1 - Digital Twin Online Channel Modeling: Theories, Measurements, and Applications

Future wireless communication is oriented to realize three-dimensional (3D) wide-area space-air-ground-sea global coverage. Base stations and users tend to move in 3D continuous spaces, while antennas and propagation environments are deeply coupled. This paradigm shift brings challenges to channel modeling, antenna design, and wireless transmission system optimization, as well as novel air interface technologies and innovative algorithms. In addition, traditional offline network optimization is unlikely to remain effective for future networks, with most networks only achieving part of their potential performance, leaving significant room for improvement. Digital twin (DT), a virtual replica of physical systems, enables real-time monitoring, analysis, and optimization for enhanced decision-making and operational efficiency. Assisted by DT, it is possible to establish virtual mappings of diverse physical systems including communication systems. This possibility promotes the development of novel paradigms for channel modeling, contributing to a more profound understanding of signal transmission processes in wireless channels. Consequently, this approach furnishes more precise references and guidance for emerging antenna optimization methods, novel air interface technologies, and innovative algorithms. To ignite further innovation and explore promising research avenues in this rapidly advancing field, this workshop endeavors to engage global experts and professionals, seeking recent advances in digital twin online channel modeling and fostering a collaborative environment for knowledge sharing.
This special session invites high-quality submissions with innovative ideas, insights, methodologies, modeling/learning frameworks, and simulation/implementation results on applying DTs in future channel modeling.
