IEEE VTC2025-Spring Workshop on: Fluid Antenna System (FAS) for 6GÂ
[Call for paper]
The upcoming sixth-generation (6G) wireless networks are expected to provide extremely high capacity, reliability, massive connectivity, and services beyond communications. In compliance with this trend, next generation reconfigurable antenna (NGRA) technologies have been proposed for enabling flexible and adaptive wireless communications. Fluid antenna system (FAS), representing any software-controllable fluidic, dielectric or conductive structures, such as mechanical liquid-based antennas, radio-frequency (RF) pixel-based antennas, movable antennas, massive array, flexible antenna array, or metasurface, etc., that can reconfigure the shape, size, position, orientation, and other radiation characteristics, has been proposed in recent years. Unlike the traditional antenna techniques where multiple antennas are discretely deployed with fixed configurations, the very fine spatial resolution and dynamic shape of FAS enable it to capitalize on the full range of spatial variations and flexibilities, resulting in significantly improved performance. Moreover, recent findings show that FAS is closely related to holographic MIMO system and reconfigurable intelligent surface (RIS). As a result, interesting discoveries can be obtained to advance the development of FAS from holographic MIMO or RIS and vice versa. FAS also offers a new capability to exploit the spatial opportunity where the interference suffers from deep fades for multiuser communication, leading to form new multiple access. This workshop aims to explore the new opportunities and address the unique challenges associated with the application of FAS for 6G. It will serve as a platform for showcasing the latest research, innovations, and practical applications of FAS. We seek original, completed, and unpublished work that is not currently under review by other journals, magazines, or conferences. Topics of interest include, but are not limited to:
Physics- and electromagnetic-compliant modeling of FAS
Electromagnetic- or information-theoretic performance limits for FAS
Advanced optimization theories and algorithms for FAS
Efficient channel estimation/extrapolation/reconstruction techniques in FAS
New coding and modulation schemes based on FAS
FAS-assisted multiple access schemes for achieving extremely massive connectivity
AI-assisted algorithms, management, and protocols for FAS
Enhancements in physical layer security and privacy through FAS
Joint communication, sensing, and/or computing designs in FAS
New reconfiguration capabilities for FAS
Interrelation between FAS and RIS, holographic MIMO systems, and other NGRA systems
Industrial trials, applications, and testbed results of FAS for 6G

IEEE Journal on Selected Areas in Communications: Special Issue on Fluid Antenna System and Other Next-Generation Reconfigurable Antenna Systems for Wireless Communications
[Call for paper]
Next-generation reconfigurable antenna (NGRA) technology has been explored as a promising solution for enabling flexible and adaptive wireless communications. Fluid antenna system (FAS) encompasses any software-controllable fluidic, dielectric or conductive structures, including but not limited to liquid-based antennas, pixel-based antennas, and metasurfaces, that can dynamically reconfigure their shape, size, position, length, orientation, and other radiation characteristics. This technology has inspired several related research studies, such as movable antenna system, flexible-position multiple-input multiple-output (MIMO) system, reconfigurable antenna MIMO system, and flexible antenna array, which can be referred to as other NGRA systems. Compared to traditional antenna systems, the reconfigurability of FAS and other NGRA systems introduces new degrees of freedom, thereby enhancing the diversity and multiplexing performance. With their ultra-high spatial resolution, FAS and other NGRA systems offer new capabilities to exploit spatial opportunities where interference naturally experiences deep fades in multiuser communications, leading to concepts such as Fluid Antenna Multiple Access (FAMA) and Compact Ultra Massive Antenna Arrays (CUMA).
Furthermore, FAS and other NGRA systems can be integrated with other enabling technologies such as reconfigurable intelligent surfaces (RIS), non-orthogonal multiple access (NOMA), rate-splitting multiple access (RSMA), integrated sensing and communications (ISAC), non-terrestrial networks (NTN), vehicular-to-everything (V2X), and more to enhance the performance of future wireless communications. Recent findings also suggest that FAS is closely related to holographic MIMO systems, offering potential advancements for both technologies. In addition, the emergence of virtual FAS presents new opportunities to improve wireless communication systems by enhancing the dimensions of the channels using AI techniques. To fully unleash the potential of FAS and other NGRA systems in future-generation wireless networks, various research challenges must be addressed, including accurate system modeling, system optimization, artificial intelligence (AI) management, multiple access and interference mitigation technologies, channel estimation, and more.Â

2024 IEEE International Conference on Communications (ICC): 1st Workshop on Fluid Antenna System for 6GÂ
[Call for paper]
The upcoming sixth-generation (6G) wireless networks are expected to provide extremely high capacity, reliability, and massive connectivity. Recently, Fluid Antenna System (FAS) has emerged as a promising technology with the potential to meet 6G ambitions. Fluid antenna refers to any software-controllable fluidic conductive structure, movable mechanical antenna structure, or even reconfigurable radio-frequency (RF)-pixels that can change its shape and position to reconfigure the gain, radiation pattern, operating frequency, and other characteristics. By near-continuously moving the antenna within a predefined area and locating it at a point where the channel has desirable conditions, FAS can improve spatial diversity and in multiuser communications make interference disappear by exploiting opportunities in fading. Unlike the traditional antenna selection techniques where multiple antennas are discretely deployed at fixed positions with sufficient separation, the very fine spatial resolution of FAS enables it to capitalize on the full range of spatial variations, resulting in significantly improved performance. Furthermore, in contrast to conventional multiple-input multiple-output (MIMO) and non-orthogonal multiple access (NOMA)/ rate-splitting multiple access (RSMA) systems that rely on complex signal processing algorithms, FAS offers a simple alternative to handle interference. This results in reduced computational overhead and system complexity, making it a more attractive solution for massive connectivity. This workshop aims to explore the potential of FAS in enabling novel applications and use cases in 6G. It will bring together researchers from academia and industry to present the latest advances and breakthroughs in FAS and to discuss the key theoretical and technical challenges faced in the design, analysis, and optimization of FAS-based communication systems. Through constructive discussion and knowledge sharing, we hope to identify potential solutions to these challenges and further refine the capabilities of FAS for 6G. We seek original, completed, and unpublished work that is not currently under review by other journals, magazines, or conferences. Topics of interest include, but are not limited to:
