Abstract

Given that fifth generation (5G) networks suggest heterogeneous networks (HetNets) design and millimeter-wave (mmWave) transmission as promising technologies to achieve its vision, we consider the downlink of a multi-user multiple-input multiple-output (MU-MIMO) HetNet operating at the region of mmWave frequencies. Actually, by focusing on a realistic assessment, the proposed framework includes the effects of channel aging, residual additive transceiver hardware impairments (RATHIs), and amplified thermal noise (ATN). After providing the definition of the coverage probability for this novel synergy between HetNets and mmWave transmission with its special characteristics under realistic conditions, we proceed with its derivation. Monte Carlo simulations verify the analytical results that allow to quantify the degradation obtained in this new paradigm, and provide interesting design insights. Hence, among others, we determine the degradation of the system due to channel aging, and we demonstrate that the RATHIs play a significant role in the high signal-to-noise ratio (SNR) regime.
