Reconfigurable Intelligent Surface-Aided Near-field Communications for 6G: Opportunities and Challenges
Xidong Mu, Jiaqi Xu, Yuanwei Liu +1
Reconfigurable intelligent surface (RIS)-aided near-field communications is investigated. First, the necessity of investigating RIS-aided near-field communications and the advantag…
Near-Field Communications: A Tutorial Review
Yuanwei Liu, Zhaolin Wang, Jiaqi Xu +3
Extremely large-scale antenna arrays, tremendously high frequencies, and new types of antennas are three clear trends in multi-antenna technology for supporting the sixth-generatio…
Simultaneously Transmitting And Reflecting (STAR) RIS for 6G: Fundamentals, Recent Advances, and Future Directions
Yuanwei Liu, Jiaqi Xu, Zhaolin Wang +3
Simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RISs) have been attracting significant attention in both academia and industry for their advant…
Performance Analysis for Near-Field MIMO: Discrete and Continuous Aperture Antennas
Ziyi Xie, Yuanwei Liu, Jiaqi Xu +2
Performance analysis is carried out in a near-field multiple-input multiple-output (MIMO) system for both discrete and continuous aperture antennas. The effective degrees of freedo…
Near-Field Communications: What Will Be Different?
Yuanwei Liu, Jiaqi Xu, Zhaolin Wang +2
The design dilemma of "What will be different between near-field communications (NFC) and far-field communications (FFC)?" is addressed from four perspectives. 1) From the channel…
Active Simultaneously Transmitting and Reflecting (STAR)-RISs: Modelling and Analysis
Jiaqi Xu, Jiakuo Zuo, Joey Tianyi Zhou +1
A hardware model for active simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RISs) is proposed consisting of reflection-type amplifiers. The amp…
