Paper Presented at HotNets 2024

We presented our paper Ultra-Reliable Low-Latency in 5G: A Close Reality or a Distant Goal? at HotNets 2024 in Irvine, California, USA.

# Abstract

Ultra-Reliable Low-Latency Communication (URLLC) was introduced in 5G to meet the stringent requirements of latencies as low as 0.5 ms and reliability levels of up to 99.999% for specific applications. Despite more than a decade of discussion, achieving these targets in real-world deployments remains a significant challenge. We argue that it is still unclear whether—and how—URLLC can be realized in practice, and that a holistic, system-level perspective addressing all inherent bottlenecks is required. Inspired by a real-world 5G testbed, we present such a comprehensive view and demonstrate how latency requirements can be met by outlining the necessary design choices across all system layers, including both processing and radio units.
