On Error Rate Analysis for URLLC over Multiple Fading Channels

© 2020 IEEE. In this paper, we study ultra-reliable and low-latency communication (URLLC) under fading using repetition diversity through multiple orthogonal radio resource blocks (e.g., multiple frequency or time bins). We investigate an approach to find an upper-bound on the packet error rate when a finite-length code is used. From simulation results, we find that the bound is reasonably tight for wide ranges of signal-to-noise ratio (SNR) and the number of multiple bins. Thus, the derived bound can be used to determine key parameters to guarantee the performance of URLLC in terms of the packet error rate.
