URLLC and eMBB in 5G Industrial IoT: A Survey

TLDR

5G‑assisted industrial IoT integrates smart devices into industrial operations, promising ubiquitous, low‑latency, high‑rate connectivity that can boost reliability and efficiency, yet most research has focused on architecture while overlooking reliability and throughput. This review surveys B5G‑assisted IIoT networks, concentrating on enhanced mobile broadband and ultra‑reliable low‑latency communication services. It examines applications and key enabling technologies, analyzing the trade‑offs between URLLC and eMBB within these networks.

Abstract

Fifth generation (5G)-industrial Internet of things (IIoT) is the integration of IIoT and a private 5G network. The IIoT is a concept that involves incorporating smart objects, gadgets, and solutions into cutting-edge industrial operations to increase reliability, efficiency, and over-production costs. Furthermore, the integration of IIoT and 5G/beyond 5G (B5G) provides the potential for ubiquitous and instantaneous connectivity. The 5G architecture can handle the IIoTs stringent ultra-low latency, real-time processing, high data rate, nearby storage, and reliability requirements. A new era of economic growth is predicted for IIoT-assisted 5G/B5G wireless networks. It should be noted that the majority of the work in IIoT is focused on the architecture, with reliability and throughput being largely ignored. This paper provides a comprehensive review of B5G assisted IIoT wireless networks, with a focus on enhanced mobile broadband (eMBB) and ultra-reliable low latency communication (URLLC) services. Furthermore, it provides insights into various applications and key enabling technologies from the perspective of URLLC, eMBB, and their tradeoff.
