Performance Analysis of mmWave Communication via Aerial Large Intelligent Surfaces

Abstract

Abstract: As a new type of reflective materials, large intelligent surface (LIS) will play a vital role in the next generation networks. By deploying LISs mounted on unmanned aerial vehicle (UAV), UAV-LIS can be used to further enhance the network coverage of LIS. In this paper, we propose a communication network model based on UAV-LIS and analyze the dual-hop transmission of millimeter wave downlink communication. Specifically, we use Poisson point process to depict the locations of users served by UAV-LIS which cruises around a base station. Then we derive the probability density function of the distance from the ground users to UAV-LIS. The analytical expression of system coverage probability can be obtained and verified by the simulation results. It turns out that the combination of LIS and UAV can greatly improve the coverage performance of millimeter wave communication system in urban areas. The developed framework is insightful for determining the network configuration by which the optimum system performance can be achieved.
