Outage Analysis of Heterogeneous mmWave Cellular Networks Employing JSDM (1901.07961v1)

Abstract: In this paper, the outage performance of a two-tier heterogeneous mmWave cellular networks employing joint spatial division and multiplexing (JSDM) is investigated. It is assumed that macro base stations (BSs) equipped with a large number of antennas and pico BSs equipped with single antenna serve users simultaneously. The two-tier BSs and users are distributed according to independent Poisson point processes (PPPs). Theoretical analysis of the signal-to-interference-plus-noise ratio (SINR) outage probability of the typical user is first provided. The all SINR outage probability of the two tiers is then derived. Simulation results in accordance with theoretical analysis demonstrating the performance improvement of two-tier networks compare with the single-tier network are provided. By using the noise-limited assumption for mmWave networks, a simpler expression to analyze the outage performance is obtained.
