Scalable GNN-Based Power Allocation for Rate-Splitting Cell-Free Massive MIMO Systems
Ruomeng Wang, Yin Xu, Aimin Tang +5
Cell-free massive multiple-input multiple-output (CF-mMIMO) systems provide enhanced coverage and capacity for next-generation wireless networks. However, CF-mMIMO systems face sig…
MA-Aided Hierarchical Hybrid Beamforming for Multi-User Wideband Beam Squint Mitigation
Cixiao Zhang, Yin Xu, Xinghao Guo +3
In wideband near-field arrays, frequency-dependent array responses cause wavefronts at different frequencies to deviate from that at the center frequency, producing beam squint and…
Joint Antenna Position and Beamforming Optimization with Self-Interference Mitigation in MA-ISAC System
Size Peng, Cixiao Zhang, Yin Xu +4
Movable antennas (MAs) have demonstrated significant potential in enhancing the performance of integrated sensing and communication (ISAC) systems. However, the application in the…
Fluid Antenna-Aided Robust Secure Transmission for RSMA-ISAC Systems
Cixiao Zhang, Yin Xu, Size Peng +5
This paper leverages fluid antenna (FA) and rate-splitting multiple access (RSMA) to enhance the physical layer security (PLS) of an integrated sensing and communication (ISAC) sys…
Sum Rate Maximization for Movable Antenna-Aided Downlink RSMA Systems
Cixiao Zhang, Size Peng, Yin Xu +5
Rate splitting multiple access (RSMA) is regarded as a crucial and powerful physical layer (PHY) paradigm for next-generation communication systems. Particularly, users employ succ…
