Autonomous Sensing UAV for Accurate Multi-User Identification and Localization in LAWN

This paper presents an autonomous sensing framework for identifying and localizing multiple users in Fifth Generation (5G) cooperative networks using an Unmanned Aerial Vehicle (UAV) that is not part of the serving access network. Unlike conventional aerial serving nodes, the proposed UAV operates passively and is dedicated solely to sensing. Passively receiving Uplink (UL) Sounding Reference Signals (SRS), the UAV requires only minimal initial coordination with the network infrastructure during the mission.
