Abstract
Inter-cell interference is one of important factors in drone small cells (DSCs). However, most works investigated the network performance of DSC networks with an assumption of interference-free. To achieve a realistic analysis, we analyze the coverage probability and achievable rate of DSC networks under inter-cell interference. However, the air-to-ground channel between DSCs and ground users consists of probabilistic line-of-sight (LoS) and non-line-of-sight (NLoS) links, which brings challenges to calculate the inter-cell interference. In this paper, we model the inter-cell interference by using equivalent uniform density plane-entity method first. Then, we study coverage probability and achievable rate considering Rician fading in LoS links and Rayleigh fading in NLoS links. Final, we show the impact of deployment density in numerical results, finding that there exists optimal deployment density that achieves best coverage performance.
