New wave of the technology revolution, often referred to as the fourth industrial revolution, is changing the way we live, work, and communicate with each other. These days, we are witnessing the emergence of unprecedented services and applications requiring lower latency, better reliability massive connection density, and improved energy efficiency. In accordance with this trend and change, international telecommunication union (ITU) defined three representative service categories, viz., enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable and low latency communication (uRLLC). Among three service categories, physical-layer design of the uRLLC service is arguably the most challenging and problematic. This is mainly because uRLLC should satisfy two conflicting requirements: low latency and ultra-high reliability. In this article, we provide the state-of-the-art overview of uRLLC communications with an emphasis on technical challenges and solutions. We highlight key requirements of uRLLC service and then discuss the physical-layer issues and enabling technologies including packet and frame structure, multiplexing schemes, and reliability improvement techniques. |
