2025-10-09

AI Summary

Industrial 5.0 imposes stringent ultra-reliable low-latency communication (URLLC) requirements, demanding deterministic performance, robust security, and sustainable operation. Method: This paper proposes a 6G-enabled URLLC architecture and cross-layer optimization framework tailored for Industrial 5.0. It introduces the first URLLC taxonomy for this domain, integrating digital twin–enabled closed-loop control, AI-driven resource orchestration, and cross-domain coordination, while incorporating terahertz (THz) communications, reconfigurable intelligent surfaces (RIS), multi-access edge computing (MEC), and network function virtualization (NFV). Contribution/Results: The work systematically characterizes fundamental trade-offs among latency, reliability, scalability, and energy efficiency in URLLC systems; establishes a deterministic service assurance paradigm; and identifies critical challenges in security enhancement and green, sustainable architecture design—thereby delivering a scalable technical pathway for intelligent factories, remote surgery, and autonomous driving.

Abstract

The evolution from Industry 4.0 to Industry 5.0 introduces stringent requirements for ultra reliable low latency communication (URLLC) to support human centric, intelligent, and resilient industrial systems. Sixth-generation (6G) wireless networks aim to meet these requirements through sub-millisecond end-to-end delays, microsecond level jitter, and near perfect reliability, enabled by advances such as terahertz (THz) communication, reconfigurable intelligent surfaces (RIS), multi-access edge computing (MEC), and AI driven cross layer optimization. This paper presents a comprehensive review of URLLC solutions for 6G enabled industry 5.0, organized into a structured taxonomy including application domains, key technical enablers, design challenges, and performance enhancements. The survey examines emerging approaches, including digital twin integration, AI/ML based resource orchestration, Network Function Virtualization (NFV) enabled service function chaining, and cross domain networking, while mapping them to critical industrial scenarios such as smart manufacturing, connected healthcare, autonomous mobility, remote control, and next-generation mobile networks. Performance trade-offs between latency, reliability, scalability, and energy efficiency are analyzed in the context of representative state-of-the-art studies. Finally, the paper identifies open challenges and outlines future research directions to realize deterministic, secure, and sustainable URLLC architectures for Industry 5.0.
