Abstract

In this paper, we propose VarOLLA, a novel approach aimed at maximizing the throughput of 5G-RedCap devices in Industrial Internet of Things (IIoT) environments. VarOLLA addresses the sub-optimal spectral efficiency of Outer Loop Link Adaptation (OLLA) by introducing a ‘Throughput Factor’ that incentivizes adaptive decision-making based on throughput considerations. Through extensive simulations, we demonstrate significant improvements in throughput, with gains of up to 35% compared to traditional OLLA techniques, particularly in scenarios with high channel outdatedness. Moreover, VarOLLA effectively reduces consecutive transmission failures (rBLER) and achieves substantial reductions in control message overhead, up to 87.5%. Our findings highlight the strong potential of VarOLLA in IIoT networks and its significant contribution to the realization of high-performance applications during the Fourth Industrial Revolution (4IR) in the manufacturing sector.
