Throughput-Coverage Optimization in RSMA-Enabled UAV Networks Using Graph Diffusion Models

Unmanned aerial vehicle (UAV)-enabled wireless networks provide flexible coverage for ground users in dynamic and infrastructure-limited scenarios. However, when multiple UAV base stations share the same spectrum, system performance is strongly affected by UAV placement, user association, and co-channel interference. T...

An LSTM-MADDPG Framework for Joint Beamforming Control in STAR-RIS-Assisted Cell-Free Massive MIMO Network

Conventional reconfigurable intelligent surfaces (RIS)-aided cell-free massive multiple-input multiple-output (CF mMIMO) networks are inherently constrained by half-space reflection, which limits coverage expansion and flexible deployment. To overcome this issue, simultaneously transmitting and reflecting reconfigurabl...

TOC-Based Communication-Control Decoupled Optimization for Multi-User Closed-Loop Wireless Networked Control Systems

Wireless networked control systems (WNCSs) have emerged as a key enabler for modern industrial automation, interconnecting sensors, control centers, and actuators via wireless communications. However, conventional architectures based on separate optimization of control and communication lead to inefficient resource uti...

Toward Self-Evolving Agentic AI for ISAC-Enabled Low-Altitude Wireless Networks

This paper proposes a self-evolving agentic artificial intelligence (AI) framework for low-altitude wireless networks (LAWNs), introducing integrated sensing and communication (ISAC) into a unified self-evolution paradigm that transforms static foundation models with passive perception into fully autonomous, self-evolv...

Joint Beamforming and Segmentation Optimization for Segmented RIS-Assisted Cell-Free mMIMO Systems Under Perfect and Imperfect CSI

The integration of reconfigurable intelligent surface (RIS) technology with cell-free massive MIMO (CF mMIMO) enhances wireless network sum-rate performance. This paper proposes a novel segmented RIS-assisted CF mMIMO architecture for downlink transmission, where RIS elements within each segment share a common reflecti...
