To exploit the full spatial degrees of freedom (DoFs) and maximize the average secrecy rate in unmanned aerial vehicle (UAV)-assisted communication systems, this paper proposes a novel physical layer security (PLS) architecture that integrates the UAV’s 3D kinematic trajectory with its tilt angle control. This joint de...

With the development of AI-native radio access network (RAN), multi-unmanned aerial vehicle (UAV) cooperative wireless data collection based on multi-agent deep reinforcement learning (MADRL) has attracted wide attention. Existing studies rarely model the combined effects of multiple obstacles, interference, and dynami...

Edge-intelligent sensing systems demand ultra-low-power wireless connectivity to sustainably support massive sensor deployments. Ambient backscatter communication (AmBC) meets this demand by harvesting and modulating existing radio-frequency (RF) signals, eliminating dedicated carriers. However, conventional on–off key...

Reliable link maintenance is currently a critical bottleneck for unmanned aerial vehicle (UAV) swarm communications in complex electromagnetic environments where UAVs encounter both external malicious jamming and internal interference. Most recent studies have treated trajectory design and resource scheduling as decoup...
