Modeling and Performance Analysis of 3-D Heterogeneous Networks with Interference Management

Abstract

This letter proposes a general 3-D model for heterogeneous networks (HetNets). The model uses stochastic geometry to describe the different network nodes' positions in a 3-D space. In addition, a new transmission scheme is proposed to mitigate the interference problem, and the corresponding coverage probability expression in general $K$-tier HetNets is derived. Monte Carlo simulations are conducted to confirm the analytical result, the accuracy of the proposed 3-D model, and the advantage of the new scheme in enhancing interference management for HetNets.
