Survivor-Aware UAV Positioning for RIS-Assisted 6G Emergency Communications: A Deep Reinforcement Learning Approach

Sustaining service for survivor IoT devices in disaster zones where terrestrial infrastructure has failed is an open challenge in sixth-generation (6G) emergency communications. This paper studies a single UAV flying base station that serves survivor devices over power-domain NOMA, with a passive reconfigurable intelli...
