URLLC Mode Optimal Resource Allocation to Support HARQ in 5G Wireless Networks

URLLC Mode Optimal Resource Allocation to Support HARQ in 5G Wireless Networks

Ultra Reliable Low Latency Communication (URLLC) mode is a promising 5G technology for various real-time applications, such as, autonomous vehicles, augmented reality, and factory automation. Several papers on URLLC exist, however, most papers only focus on ways to achieve high reliability, and lack...
