Massive connectivity and low latency are two important challenges for the Internet of Things (IoT) to achieve the Quality of Service (QoS) provisions required by the numerous devices it is designed to service. In this paper, we propose a new method to achieve lower outage probability in millimeter wave -NOMA systems with massive multiple-input multipleoutput (MIMO) structure. We obtain a closed-form expression to minimize the outage probability. In the proposed method, random paring scheme is applied so that it eliminates the need of CSI to reduce the overhead of the system and achieve the QoS. The results demonstrate that the proposed cellular machineto-machine (M2M) communication system with the mmWave massive-MIMO-NOMA transmission scheme improves outage probability compared to previous works.
