Outage Probability of Opportunistic Self-Backhauled Millimeter Wave Mobile Networks

In this paper, we consider a downlink self-backhauled mmWave cellular system with opportunistic selection of associated small cells, controlled by a centralized anchor base station (A-BS). We assume both backhaul and access links are modeled as Nakagami-m channels concatenate with random binary blockages. We analyze the system performance by deriving the equivalent end-to-end channel distributions. Then, the derived cumulative distribution function is used to calculate the outage probability. Finally, the simulation results show the impact of different parameters and correctness of our analytical results. It is also shown that our proposed scheme outperforms maximum ratio combining detection, in which all associated self-backhaled BSs are retransmitting the decoded user message toward the typical user equipment.
