HARQ for Slow Fluid Antenna Multiple Access
Sixu Han, Kai-Kit Wong, Hanjiang Hong +1
Slow fluid antenna multiple access (sFAMA), enabled by the fluid antenna system (FAS), has recently emerged as a practical and low-complexity paradigm for supporting massive wirele…
Enormous Fluid Antenna Systems (E-FAS) for Wireless Sensing: Channel Modeling and Conditional Estimation Limits
Farshad Rostami Ghadi, Kai-Kit Wong, Jose D. Vega-Sanchez +2
In this paper, we develop a fundamental analytical framework for integrated sensing and communications (ISAC) enabled by the Enormous Fluid Antenna System (E-FAS), which transforms…
Fluid Antenna Systems Enabling 6G HRLLC With Port Switching Delay
Xusheng Zhu, Kai-Kit Wong, Hao Xu +2
Fluid antenna systems (FAS) exploit antenna position reconfigurability to unlock massive spatial diversity within compact form factors, making them a promising enabler for 6G user…
Geometry-Structured Channel Reconstruction for Conventional and Fluid Antenna Systems: Bayesian Inference and Fundamental Limits
Zhentian Zhang, Kai-Kit Wong, Kaitao Meng +5
Accurate channel state information (CSI) acquisition is critical for exploiting the spatial flexibility of fluid antenna systems (FASs). However, port selection and transmission op…
Fluid RIS (FRIS)-Assisted Index Modulation for 6G Wireless Communications
Xusheng Zhu, Kai-Kit Wong, Sai Xu +3
Fluid reconfigurable intelligent surfaces (FRIS) extend conventional reconfigurable intelligent surfaces (RIS) by adding spatial reconfigurability through switchable apertures, pat…
Finite-Aperture Planar Fluid Antenna Array
Zhentian Zhang, Jingyuan Xu, Kai-Kit Wong +3
Fluid antenna systems (FASs) are emerging as a reconfigurable-aperture technology that expands physical-layer design beyond fixed, rigid antenna geometries. While the \emph{fading…
