System-Level Analysis for Full-Duplex MmWave Cellular Networks

Abstract

In this paper, we investigate the performance of full-duplex (FD) radio in large-scale heterogeneous millimeter-wave (mmWave) cellular networks. The FD radio can potentially double the spectral efficiency but its performance is compromised by the existence of loop- and multi-user interference compared to half-duplex radio. Using stochastic geometry tools, we derive closed-form expressions for the coverage probability and the sum-rate performance of the considered network. We evaluate the impact of the FD radio on the network performance and quantify the associated gains under different network parameter settings. Our results demonstrate that the combination of FD radio with heterogeneous mmWave cellular networks provides significant gains, since it increases the spectral efficiency but also alleviates the effects of the multi-user interference.
