This letter investigates a receiver-side fluid antenna system (FAS)-assisted multiuser multi-input single-output downlink system under severe inter-user spatial correlation. We derive closed-form analytical achievable sum rate expressions based on linear precoding, which explicitly decompose the per-user effective chan...

The analytical FAS results are conservative relative to simulation but preserve the performance trends and receiver ordering, while the FAS receiver consistently outperforms the benchmarks, while the payload-throughput gain from increasing the HARQ transmission limit becomes marginal under severe multiuser interference...
Fluid antenna arrays (FAAs), support multiuser downlink transmission by activating a subset of reconfigurable ports. The activation mask jointly determines the effective channel and the sparse radiating aperture, which requires a balance among sum rate, sidelobe suppression, hardware constraints, and online complexity....

A downlink hybrid automatic repeat request (HARQ)-assisted sFAMA framework, termed HARQ-sFAMA, in which each user performs distinguished port selection in every HARQ round and combines the received signals across multiple rounds to improve decoding reliability and energy efficiency is studied.
