Talk Title: Finite-blocklength Fluid Antenna Systems: Theory and Application

6G and beyond networks are designed to support demanding applications like mMTC, URLLC, and eMBB. To meet these requirements, operation in the finite blocklength (FBL) regime has become crucial. FBL-based multiple-antenna systems leverage spatial diversity to optimize performance under limited channel uses. The fluid antenna system (FAS) offers a promising solution by dynamically adjusting its radiation characteristics through software-controlled fluidic or conductive elements, enabling significant diversity gains in compact form factors. FAS shows great potential in applications such as multiple access and integrated sensing and communication. However, the performance of FAS under the FBL regime remains an open problem. This talk will introduce recent advances in FBL-FAS systems, including newly developed performance metrics, analytical models, and channel modeling techniques. Practical use cases, such as FBL-FAS for multiple access, sensing-communication integration, and low-complexity channel reconstruction, will also be discussed, highlighting its potential for future 6G networks.
