Machine Learning for Wireless Metaverse: Fundamentals, Use Case, and Future Directions

Latif U. Khan, Ibrar Yaqoob, Khaled Salah, Choong Seon Hong, Dusit Niyato, Zhu Han, Mohsen Guizani

TL;DR

The paper addresses how to realize metaverse-enabled wireless networks that meet diverse QoS/QoE requirements by coupling a two-space architecture (meta space and physical space) with ML-driven proactive learning and self-sustainability. It presents a case study of a multi-agent deep reinforcement learning framework with dueling DDQN and a convex optimizer to optimize metaverse sensing, where the system builds a cost function $\mathcal{C}$ and uses a reward of $1/\mathcal{C}$. The results indicate the proposed DDQN+sensing+dueling scheme outperforms traditional DDQN in convergence and QoS satisfaction, offering a practical MINLP-to-RL solution path. The work outlines forward-looking directions—Gen-AI for content generation, intelligent resource scheduling, and standardized interfaces—to enable scalable, ML-enabled metaverse wireless systems.

Abstract

Today's wireless systems are posing key challenges in terms of quality of service and quality of physical experience. Metaverse has the potential to reshape, transform, and add innovations to the existing wireless systems. A metaverse is a collective virtual open space that can enable wireless systems using digital twins, digital avatars, and interactive experience technologies. Machine learning (ML) is indispensable for modeling twins, avatars, and deploying interactive experience technologies. In this paper, we present the role of ML in enabling metaverse-based wireless systems. We discuss key fundamental concepts for advancing ML in the metaverse-based wireless systems. Moreover, we present a case study of deep reinforcement learning for metaverse sensing. Finally, we discuss the future directions along with potential solutions.
