Opportunistic Multiple Access for Reliable Minimal Latency Communications

Ultra-Reliable Low Latency Communication (URLLC) remains a daunting challenge toward 6G, of particular interest in use cases involving machine-to-machine communications and Extended Reality (XR) applications. Proactive communication was proposed to effectively establish URLLC for minimal latency. In this paper, we further innovate opportunistic multi-access of proactive virtual cell communications for smart machines. We employ game-theoretic analysis to explore the fundamental behavior of such a decentralized mechanism. Instead of optimizing throughput in traditional wireless access, maximizing ultra-reliability by a strategy-proof proactive mechanism of multi-cell networking architecture disruptively achieves minimal latency without the need for any additional control overhead, whose impressive performance is further confirmed by numerical evaluations.
