Abstract
Machine-Type Communication (MTC) is a rapidly growing technology which covers
a broad range of automated applications and propels the world into a fully
connected society. Two new use cases of MTC are mMTC and URLLC, where mMTC
support a large number of devices with high reliability and low rate
connectivity while URLLC refers to excessively low outage probability under
very stringent latency constraint. Herein, we examine the URLLC through three
cooperative schemes, namely dual-hop DF, SC and MRC, and compare to direct
transmission under Rayleigh fading. We compare the performance of studied
cooperative protocols under two distinct power constraints with respect to
latency and energy efficiency. Moreover, we illustrate the impact of coding
rate on the probability of successful transmission in ultra-reliable region in
addition to the effect of power allocation on the outage probability. We also
provide the performance analysis of cooperative schemes in terms of energy
efficiency and latency requirements.
