Ultra reliable and low latency communications (URLLC) is a new use case in 5G wireless systems to accommodate emerging mission-critical services and applications. These include driverless vehicles and drone-based deliveries, smart cities and factories, remote medical diagnosis and surgery, and artificial intelligence-based personalized assistants. In order to support URLLC, there should be changes in the air interface (a.k.a. physical-layer). In this article, we provide physical layer challenges and solutions in 5G URLLC downlink. We discuss requirements of URLLC and then present the physical layer issues and new solutions including data structure, multiplexing schemes, and reliability assurance technologies, which have been adopted in the 5G new radio (NR).
