To meet the diverse industrial and market demands, the International Telecommunication\nUnion (ITU) has classified the fifth-generation (5G) into ultra-reliable low latency communications\n(URLLC), enhanced mobile broadband (eMBB), and massive machine-type communications (mMTC).\nResearchers conducted studies to achieve the implementation of the mentioned distributions efficiently,\nwithin the available spectrum. This paper aims to highlight the importance of URLLC in accordance\nwith the approaching era of technology and industry requirements. While highlighting a few\nimplementation issues of URLLC, concerns for the Internet of things (IoT) devices that depend on\nthe low latency and reliable communications of URLLC are also addressed. In this paper, the recent\nprogress of 3rd Generation Partnership Project (3GPP) standardization and the implementation of\nURLLC are included. Finally, the research areas that are open for further investigation in URLLC\nimplementation are highlighted, and efficient implementation of URLLC is discussed.
