6DMA-FIM-Enabled User-Centric Cell-Free Massive MIMO With Two-Layer RSMA

This paper proposes a novel user-centric (UC) cell-free massive MIMO (CF-mMIMO) architecture empowered by six-dimensional movable antennas (6DMA) and flexible intelligent metasurfaces (FIM), integrated with a two-layer rate-splitting multiple access (RSMA) framework. Unlike conventional fixed-position deployments, the...

Polarforming-Enabled Power-Splitting SWIPT: A GNN-Based Optimization Approach

Simultaneous wireless information and power transfer (SWIPT) is a critical technology for the future of the Internet of Things (IoT). However, ensuring a stable power supply in such networks remains a significant challenge. This work introduces dynamic polarization control as an additional degree of freedom (DoF) in SW...

GNN-Based Polarforming for Multi-User MISO Short-Packet URLLC under Imperfect CSI

This paper investigates polarization-aware transmission for multi-user multiple-input single-output (MU-MISO) short-packet ultra-reliable low-latency communications (URLLC) under imperfect channel state information (CSI). We consider a system in which the base station (BS) and users are equipped with polarization-recon...
