Abstract
Industrial IoT (IIoT) is considered as the disruptive use case for 5G and Beyond networks, as it enables novel applications such as remote control of machines/robots and autonomous driving. The 5G service that was envisioned for serving IIoT is Ultra Reliable Low Latency Communications (URLLC), as it ensures stringent Quality of Service (QoS) with a reliability of 99,999% and a target latency of 1 ms. In this talk, we present how these stringent QoS requirements can be met with the lowest cost in terms of radio resource consumption, both in the downlink, where the queueing delay is preponderant, and in the uplink, where the main delay component is caused by the channel access procedure.
We then explore new trends in IIoT systems, with two different axes of evolution. The first trend is a natural evolution of URLLC towards extreme URLLC in 6G networks, where the delay target is as low as 0.1 ms, with a reliability of 99,99999%. We show how these stringent requirements can be met and with which cost. Based on these results, we advocate a different approach for 6G networks, that is based on the goal-oriented communications paradigm. In this approach, the network does not have to constantly ensure a stringent QoS requirement, but will adapt to the goal of the application and transmit only the amount of data needed for reaching the goal. We show using practical examples that this approach has a clear advantage in terms of energy and resource consumption.
Short Bio
Salah Eddine Elayoubi received his M.S. degree from the National Polytechnic Institute of Toulouse, France, in 2001, and his Ph.D. and Habilitation degrees in computer science from the University of Paris VI, France, in 2004 and 2009, respectively. From 2004 to 2017 he was with Orange Labs in France. Since 2018, he is a full professor at CentraleSupélec, France, and researcher at L2S laboratoire of the CNRS, where he leads a research team about mathematical tools for networks. He is holder of the Sustainable 6G research chair, funded by Orange. His main area of interest is 5G/6G network design.
