Intelligent Reflecting Surface Placement Optimization in Cellular Communication Networks for Aerial Vehicles

Abstract (in Japanese) (See Japanese page) 
(in English) One of the key requirements for sixth-generation (6G) networks is to support the aerial vehicle communications, which is the data transmission between terrestrial bese station (BS) and aerial users (AUs). However, there are challenges in providing wireless communication for aerial users due to the different radio wave propagation properties between terrestrial areas and aerial areas. In this article, we propose an IRS-aided cellular network coverage extension for aerial users. In the proposed network, IRS and base stations (BSs) cooperate with each other to provide the air-ground communication to aerial users (AUs), the aim of which is to prevent interference signals from spreading to a wide area. Furthermore, IRS placement optimization problem (IPOP) is formulated to maximize the network performance in terms of the spatial signal-to-interference plus noise ratio (SINR) while mitigating the inter-cell interference. Numerical analysis results indicate that the proposed IRS-aided network outperforms the benchmark system without IRSs when the IRS installation positions are optimally determined.
