Abstract

5G and beyond networks will use, for the first time, the millimeter wave (mmWave) spectrum for mobile communications. An accurate performance evaluation is fundamental for the design of reliable mmWave networks, with the accuracy depending on the fidelity of the channel models. At mmWaves, a model needs to account for the spatial characteristics of the propagation, and for the interaction of transmitted signals with the scenario. In this regard, Quasi-Deterministic (QD) models are highly accurate channel models, which characterize the propagation in terms of clusters of multipath components, given by a reflected ray and multiple diffuse components. This paper introduces a detailed mathematical formulation for QD models at mmWaves, that can be used as a reference for their implementation and development. Moreover, it compares channel instances obtained with an open source NIST QD model implementation against real measurements at 60 GHz.
