Toward Hyper-Dimensional Connectivity in Beyond 6G: A Conceptual Framework

TL;DR

The paper addresses the need for beyond-6G connectivity by proposing a conceptual framework called hyper-dimensional connectivity, integrating four core dimensions—communication, cognition, computing, and cyber-physical integration—to enable hyper-immersive Internet experiences. It provides technical definitions, a set of use cases with corresponding system-level requirements, technology enablers across spectrum, antennas, transmission, architecture, intelligence, security, and terminals, and a forward-looking research agenda. The authors argue for advancing beyond IMT-2030 with post-quantum security, zero-trust orchestration, AI-native distributed intelligence, and sustainable design to support a planetary cyber-physical ecosystem. The work aims to guide innovation, standards development, and long-term technical goals for a scalable, secure, and resilient hyper-real Internet that tightly couples physical and digital realities.

Abstract

Cellular wireless networks enable mobile broadband connectivity for Internet-based applications through their radio access and core network infrastructure. While Fifth-Generation (5G) cellular systems are currently being deployed, ongoing research on cellular technologies primarily focuses on Sixth-Generation (6G) networks to set the stage for developing standards for these systems. Therefore, the time has come to articulate the visions for beyond 6G (B6G) systems. In this article, we present a visionary framework toward hyper-dimensional connectivity in B6G that enables wireless access to hyper-immersive Internet technologies. Our contributions include a conceptual framework for B6G cellular systems with jointly integrated communication, cognition, computing, and cyber-physical capabilities as core connectivity dimensions, a set of technical definitions outlining potential use cases and system-level requirements, a mapping of prospective technology enablers, and a forward-looking research agenda for B6G systems. The conceptual discussions in this article would be helpful for identifying innovation drivers, shaping long-term technical goals, and defining research agendas for the future of mobile broadband technologies.
