Into The Wireless Metaverse: A Rendez-Vous Between 6G Systems and Artificial Intelligence (AI)



Abstract: The metaverse is set to revolutionize the way people interact, communicate, and conduct business, blurring the lines between virtual, digital, and physical worlds. This transformation is critical for the advancement of tomorrow's Society 5.0, where a harmonious integration of cyber and physical spaces can address emerging social challenges while boosting economic progress. However, deploying the metaverse at scale to enable global interactivity requires a confluence of cutting-edge technologies, from wireless communication systems to digital twins, extended reality, and artificial intelligence (AI). In this talk, we explore new frameworks for the synergistic integration of these technologies, and explore how this integration has the potential to catalyze the deployment of a limitless, wireless metaverse. We start by investigating whether key capabilities of 6G systems, such as terahertz communications and mobile edge computing, can deliver the physical experience and synchronization necessary to create a seamless connection between the virtual and physical worlds. We then examine the advancements required in the field of AI to achieve cognition and reasoning in wireless networks. In this space, we first discuss the role of continual learning in synchronizing digital twins in the metaverse. Then, we introduce a holistic vision for semantic communications that is firmly grounded in rigorous AI foundations, with the potential to revolutionize the way information is modeled, transmitted, and processed in communication systems We show how, by embracing semantic communication through our proposed vision, we can usher in a new era of knowledge-driven, reasoning wireless networks that are more sustainable and resilient than today's data-driven, knowledge-agnostic networks. As a first step towards enabling this paradigm shift, we present our recent key results in this area that showcase how the use of semantic communications can reduce the volume of data circulating in a network while improving reliability, two critical requirements for the metaverse and its applications. We conclude by articulating a research roadmap that delineates the requisite innovations at the confluence of AI, 6G, and computing to fully realize the potential of the wireless metaverse.
