abstract
Different from traditional offline channel modeling, digital twin online channel modeling can sense and accurately characterize dynamic wireless channels in real time, and can therefore greatly assist 6G network optimization. This article proposes a novel promising framework and a step-by-step design procedure of digital twin online channel models (DTOCM). By enabling continuous visualization and accurate prediction of dynamic channel variations, DTOCM can synchronize the performance between simulated and real networks. We first explore the evolution and conceptual advancements of DTOCM, highlighting its visions and associated challenges. Then, we explain its operational principles, construction mechanisms, and applications to typical 6G scenarios. Subsequently, the real-time channel information provisioning and visualization capabilities of DTOCM are illustrated through our DTOCM platform based on practical scenarios. Finally, future research directions and open issues are discussed.
