Resource Allocation In Cellular Networks With Unmanned Aerial Vehicles.

Abstract

The integration of aerial user equipment(UEs) into existing cellular networks will provide possible number of applications but current cellular networks have not been designed to serve aerial users. The main challenges that need to be addressed when planning the deployment of aerial UEs are whether the cellular network suits both unmanned aerial vehicles and ground users in connectivity and thus investigate how the inclusion of aerial UEs impact the quality of experience for ground users that share frequency. An exploration of design parameters is required for ubiquitous and reliable connectivity to allow safe control and data exchange between these devices and ground stations. Our simulations analysis provides the coverage probability of the down-link propagation condition of the cellular network that serves both aerial and ground users. Our simulations results show that favorable propagation conditions for aerial users due to free space decrease with increased altitude, and antenna tilt increases coverage and throughput considerably. In this research, probability of coverage against Signal to Interference Ratio (SIR), Interference Temperature Limit and distance from serving BS were used as the basis to measure how feasible the connectivity of both UAV-UEs and ground users in cellular networks be.
