Ultra-Reliable and Low-Latency Communications for Industry 4.0

Future wireless networks need to provide Ultra-Reliable and Low-Latency Communications (URLLC) for Industry 4.0, which is also one of the major goals in the fifth generation (5G) communication systems. In this tutorial, we will discuss some fundamental design aspects and challenges to enable real-time industrial applications in future wireless networks. In particular, we will show our remote robotic control testbed in Glasgow University, UK. Specifically, we start from industrial perspective to introduce the basic requirements of wireless communications for Industry 4.0, which covers several industrial use cases. Then, we discuss the inter-dependencies between wireless communication and industrial control systems, and introduce the system design from the perspective of communication-control co-design. Finally, we discuss the URLLC design, open problems, and potential research directions from academic perspective, which covers physical (PHY) and media access control (MAC) layers.
