Downlink Analysis of HetNets with Millimeter Wave Small Cells
In this paper, the performance of a heterogeneous cellular network with both traditional sub-6GHz and millimeter wave (mmWave) links is investigated. Different from prior analysis, the interference in mmWave frequency band is incorporated into our model. Using the tools from stochastic geometry, the SINR coverage probability under maximum bias average received power association strategy is derived. The effect of sub-6GHz and mmWave small cells (SCs) density on the coverage probability is also analyzed to give insights on the network deployment. Simulation results validate the accuracy of our analysis, and reveal that different kinds of SCs have various influence on the network and need to be deployed properly.
