Latency prediction in 5G for control with deadtime compensation

Abstract

With the promise of increased responsiveness and robustness of the emerging 5G technology, it is suddenly becoming feasible to deploy latency-sensitive control systems over the cloud via a mobile network. Even though 5G is herald to give lower latency and jitter than current mobile networks, the effect of the delay would still be non-negligible for certain applications.In this paper we explore and demonstrate the possibility of compensating for the unknown and time-varying latency introduced by a 5G mobile network for control of a latency-sensitive plant. We show that the latency from a prototype 5G test bed lacks significant short-term correlation, making accurate latency prediction a difficult task. Further, because of the unknown and time-varying latency our used simple interpolation-based model experiences some troubling theoretical properties, limiting its usability in real world environments. Despite this, we give a demonstration of the strategy which seems to increase robustness in a simulated plant.

From 5G to 6G Technology: Meets Energy, Internet-of-Things and Machine Learning: A Survey

“…By modifying the edge network, primarily eNodeB, the proposed protocol will combine IoT traffic with traditional systems. Other articles [147,148] discussed the existing proposed spectrum for 5G and the internet of things, as well as licenced, unlicensed, and licenced shared access schemes for future generations, as well as deployment scenarios for countries and effective ranges to achieve better results for harmonised spectrum. Also, investigate and illustrate how to compensate for the uncertain and time-varying latency introduced by a 5G mobile network when controlling a latency-sensitive plant.…”
