Abstract

6th-Generation (6G) networks seek improved coverage and efficiency, with Reconfigurable Intelligent Surfaces (RISs) offering a way to create adaptable radio environments. Achieving optimal performance in RIS-assisted systems, especially with multiple antennas, depends on precise channel estimation. This letter introduces enhanced methods for separate channel estimation that lower pilot overhead and improve efficiency by using deterministic channel models and optimal RIS configurations, addressing challenges in large-scale RIS deployments for next-generation networks.

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
