Task-Agnostic Semantic Communications Relying on Information Bottleneck and Federated Meta-Learning
Hao Wei, Wen Wang, Wanli Ni +4
As a paradigm shift towards pervasive intelligence, semantic communication (SemCom) has shown great potentials to improve communication efficiency and provide user-centric services…
Multi-Functional RIS Integrated Sensing and Communications for 6G Networks
Dongsheng Han, Peng Wang, Wanli Ni +4
In this paper, we propose a novel multi-functional reconfigurable intelligent surface (MF-RIS) that supports signal reflection, refraction, amplification, and target sensing simult…
Channel Estimation and Beamforming Design for MF-RIS-Aided Communication Systems
Zaihao Pan, Wen Wang, Gaofeng Nie +2
In this letter, we study the beamforming design for channel estimation of multi-functional reconfigurable intelligent surface (MF-RIS)-aided multi-user communications that supports…
Two Birds With One Stone: Enhancing Communication and Sensing via Multi-Functional RIS
Wanli Ni, Wen Wang, Ailing Zheng +5
In this article, we propose new network architectures that integrate multi-functional reconfigurable intelligent surfaces (MF-RISs) into 6G networks to enhance both communication a…
