Agentic World Modeling for 6G: Near-Real-Time Generative State-Space Reasoning

arXiv 25.11 2025 49.3 method, application

TLDR

Proposes WM-MS3M, a generative world model for 6G O-RAN near-real-time control, enabling counterfactual what-if forecasting with improved efficiency.

Reasoning

The paper presents a novel world modeling approach for 6G networks, with clear methodology and empirical results on real O-RAN traces. Strengths include concrete performance gains and reduced parameters; weaknesses include limited scope to a specific domain and lack of comparison to broader world model benchmarks.

Methodology

The paper proposes WM-MS3M, which combines multi-scale structured state-space mixtures (MS3M) with a compact stochastic latent to form a generative state-space world model. Actions such as physical resource blocks (PRBs) are treated as first-class control inputs, and both aleatoric and epistemic uncertainty are modeled. An agentic model predictive control (MPC)-based cross-entropy method (CEM) planner operates over short horizons, using prior-mean rollouts within data-driven PRB bounds to maximize a deterministic reward. The model is evaluated on realistic O-RAN traces, comparing against MS3M and attention/hybrid baselines using MAE, RMSE, and inference latency.

Key Results

WM-MS3M reduces mean absolute error (MAE) by 1.69% compared to MS3M with 32% fewer parameters and similar latency, and achieves 35-80% lower root mean squared error (RMSE) than attention/hybrid baselines with 2.3-4.1x faster inference, enabling rare-event simulation and offline policy screening.
