In the upcoming 5G and beyond systems,ultra-reliable and low latency communication(URLLC)has been considered as the key enabler to support diverse mission-critical services,such as industrial automa-tion,remote healthcare,and intelligent transportation.However,the two stringent requirements of URLLC:extremely low latency and ultra-strict reliability have posed great challenges in system designing.In this article,the basic concepts and the potential applications of URLLC are first introduced.Then,the state-of-the-art research of URLLC in the physical layer,link layer and the network layer are overviewed.In addition,some potential research topics and challenges are also identified.
