Embodied AI in 6G Networks: From Intelligent Connectivity to Physical Intelligence

A tutorial perception--communication--action (PCA) architecture is developed that exposes task state, action deadlines, uncertainty, agent intent, and safety envelopes to a 6G orchestration plane and shows where network orchestration improves task utility and where local autonomy remains essential.

A Lorentzian Dispersion Model for Stacked Intelligent Metasurfaces

Stacked intelligent metasurfaces (SIM) provide a low-power means for MIMO transmission and reception using large multi-layer apertures that are digitally controlled. In this letter, we develop a SIM model that is consistent with metasurface theory. We use the Lorentzian function to emulate the amplitude-phase trade-off...

JEPA for AI-Native 6G: Predictive Representations and Open Challenges

A wireless-oriented tutorial on JEPA for 6G intelligence is presented and an illustrative, beam-management case study is presented suggesting that a wireless-aware target, specifically an auxiliary future beam-energy target during self-supervised pretraining, can improve label efficiency and robustness across shifted d...
