The Geometry-aware Frame Network is developed, which projects channel frequency responses onto a physics-derived delay--angle-of-arrival lattice and aggregates sign-robust evidence across orthogonal frequency-division multiplexing symbols to form a shared geometry posterior over physically feasible candidates.

A fluid antenna system (FAS) can improve both energy harvesting and data transmission in wireless powered communication (WPC) by exploiting spatial diversity with a single RF chain. In this letter, we study the outage probability of a FAS-assisted WPC network under the port selection criterion that maximizes the produc...

Dual-tier unmanned aerial vehicle (UAV) networks have emerged as a promising architecture for enabling flexible and on-demand services in low-altitude wireless environments. However, the high mobility of UAVs and the dynamic nature of wireless channels introduce significant challenges for beam selection, particularly i...
