Ultra-reliability and low-latency are two key components in 5G networks. Inthis letter, we investigate the problem of ultra-reliable and low-latencycommunication (URLLC) in millimeter wave (mmWave)-enabled massivemultiple-input multiple-output (MIMO) networks. The problem is cast as anetwork utility maximization subject to probabilistic latency and reliabilityconstraints. To solve this problem, we resort to the Lyapunov technique wherebya utility-delay control approach is proposed, which adapts to channelvariations and queue dynamics. Numerical results demonstrate that our proposedapproach ensures reliable communication with a guaranteed probability of99.99%, and reduces latency by 28.41% and 77.11% as compared to baselines withand without probabilistic latency constraints, respectively.
