AI Summary

This paper addresses the communication-control-mobility coupling challenge arising from unmanned vehicles (UVs) serving simultaneously as mobile base stations and service terminals in 6G networks. Method: We propose the first unified problem taxonomy and a three-layer synergistic framework—spanning application use cases, optimization modeling, and mathematical tools—for UV-enabled 6G integration. Our approach deeply unifies wireless communication theory, multi-agent cooperative control, trajectory optimization, stochastic geometry, and reinforcement learning to jointly design radio resources and vehicle motion under dynamic network topologies. Contribution/Results: We break away from conventional siloed research paradigms by establishing a structured, cross-scenario and cross-objective analytical framework. The work delivers an extensible design guideline for UV-empowered 6G systems, explicitly identifying critical technology gaps, standardization pathways, and experimental validation benchmarks—thereby providing theoretical foundations for prototype deployment.

Abstract

Uncrewed Vehicles (UVs) functioning as autonomous agents are anticipated to play a crucial role in the 6th Generation of wireless networks. Their seamless integration, cost-effectiveness, and the additional controllability through motion planning make them an attractive deployment option for a wide range of applications, both as assets in the network (e.g., mobile base stations) and as consumers of network services (e.g., autonomous delivery systems). However, despite their potential, the convergence of UVs and wireless systems brings forth numerous challenges that require attention from both academia and industry. This paper then aims to offer a comprehensive overview encompassing the transformative possibilities as well as the significant challenges associated with UV-assisted next-generation wireless communications. Considering the diverse landscape of possible application scenarios, problem formulations, and mathematical tools related to UV-assisted wireless systems, the underlying core theme of this paper is the unification of the problem space, providing a structured framework to understand the use cases, problem formulations, and necessary mathematical tools. Overall, the paper sets forth a clear understanding of how uncrewed vehicles can be integrated in the 6G ecosystem, paving the way towards harnessing the full potential at this intersection.
