Data power optimization algorithm for downlink multi-ARS small cell communication systems

In this paper, we investigate a novel downlink Small Cell (SC) system based on the Cell Free (CF) model, with the deployment of Unmanned Aerial Vehicles (UAVs) as Aerial Relay Stations (ARSs) simultaneously serving users in a specific area. The new SC model concept is expressed in the user-centric idea that the user will choose only one ARS with the best conditions for communication, and the concept of “cell" or “cell boundary" will no longer exist.
