Leveraging CKM for Predictive Communication, Channel Estimation, and Network Planning | Jie Xu

Описание: Channel Knowledge Map (CKM), as an enabling technology for environment-aware wireless communications in 6G, characterizes the spatial correlations among geographic locations, propagation environments, and channel characteristics. It provides a new paradigm for wireless networks to evolve from passive response to proactive prediction and intelligent planning. This lecture focuses on the utilization of CKM in predictive communications, channel estimation, and network planning. First, the basic concepts and main types of CKM are introduced, together with their fundamental roles in environment-aware communications. Next, the utilization of CKM for predictive communications is discussed, including reducing beam training overhead and enabling efficient channel estimation for large-scale antenna arrays with the assistance of sensing information. Finally, the utilization of CKM in network planning is examined through two representative scenarios: low-altitude network planning and intelligent reflecting surface deployment.
