Reconfigurable antennas are increasingly integrated into multi-antenna communication systems to exploit large apertures while reducing the hardware complexity, energy consumption, and implementation costs of classical massive arrays. Their reconfigurable electromagnetic (EM) properties, including dynamically varying ra...

Channel2World is proposed, a wireless foundation model that learns a reusable environment-level representation from multiple-input multiple-output (MIMO) channel-position observations that generalizes across deployments and provides effective conditioning in unseen environments.

GeoSetPPO is proposed, a geometry-aware set-attention proximal policy optimization (PPO) method that outputs per-UAM discrete association and subband decisions with permutation-invariant representations that demonstrates stable convergence, higher returns, and favorable reward and schedule-feasibility performance relat...

The proposed framework achieves higher average EE than a traffic-agnostic always-on MIMO baseline, while maintaining comparable throughput at peak hours, and is extended to a traffic-aware setting with realistic user trajectories from the multi-agent transport simulator.
