Ultra Reliable and Low latency Communication (URLCC) for 5G, IoT, Time Sensitive networking and V2X communication

Speaker:  Shahid Mumtaz – AVEIRO, Portugal
Topic(s):  Networks and Communications


New services and applications requiring lower latency, better reliability, massive connection density, and improved energy efficiency are emerging in an unprecedented fashion. A variety of advanced features make 5G uniquely well positioned to meet all of these requirements and capitalize on these market opportunities. A prime example is Ultra-Reliable Low-Latency Communication (URLLC), a set of features designed to support mission-critical applications such as the industrial internet, smart grids, remote surgery, and intelligent transportation systems. With 4G LTE, latency is currently in the 4-millisecond range under 3GPP Release 14. URLLC is part of Release 15 and has a target of 1-millisecond. URLLC also is ideal for applications that require end-to-end security and 99.999 percent reliability, and it’s almost deterministic in time bounds on packet delivery. The physical layer is unquestionably the most challenging because URLLC must satisfy two conflicting requirements: low latency and ultra-high reliability. This combination is a vastly different type of quality of service (QoS) compared to traditional mobile broadband applications. Alongside with Physical layer, URLLC application also requires low latency backhaul and fronthaul. Ethernet is known as a widely available low-cost technology suitable for data and telecom networks. However, for meeting the extreme latency requirements, Time-Sensitive Network (TSN) features, composed of techniques for lowering the latency in networks, may be considered. Therefore, in this presentation, we will explain the different URLLC solutions for 5G and Time Sensitive networking with its applications to IoT and V2x communication.
