Active Perception for Radio Map Reconstruction in Uncharted 3D Air-Ground Environments
Wenlihan Lu, Miaowen Wen, Shijian Gao
Radio maps provide the essential foundation for low altitude networking systems. Unlike terrestrial radio maps that are typically generated via drive test measurements, mapping the…
Learn to Access and Backhaul the Sky: Multi-Scale Radio Map Guided Multi-UAV Cooperation
Yifeng Yuan, Shijian Gao
Driven by the emerging low-altitude economy, uncrewed aerial vehicle (UAV) swarms offer flexible integrated air-ground access and backhaul. However, providing seamless connectivity…
TeRFS: Temporal-Evolving Radio Field Synthesis
Pengyang Zhang, Wenlihan Lu, Shijian Gao
While radio-frequency (RF) field synthesis is fundamental to wireless networking, current approaches remain constrained by static assumptions, leaving them unable to track the rapi…
Dynamic Task and Resource Scheduling Towards Green Space-Air-Ground-Sea Integrated Network
Yufei Ye, Shijian Gao, Xinhu Zheng +1
In the context of 6G ubiquitous connectivity, the space-air-ground-sea integrated network (SAGSIN) emerges as a new paradigm to provide critical services for resource-limited ocean…
Scalable Multimodal Beam Alignment in V2X: An Anti-Imbalance Graph Learning Approach
Jiahui Liang, Shuoyao Wang, Shijian Gao
Efficient beam alignment is fundamental to high-throughput and reliable connectivity in Vehicle-to-Everything (V2X) systems. However, conventional beam management in dynamic vehicu…
Transfer to Sky: Unveil Low-Altitude Route-Level Radio Maps via Ground Crowdsourced Data
Wenlihan Lu, Huacong Chen, Ruiyang Duan +2
The expansion of the low-altitude economy is contingent on reliable cellular connectivity for unmanned aerial vehicles (UAVs). A key challenge in pre-flight planning is predicting…
