Abstract
The sixth-generation (6G) wireless communication network needs to achieve very high data rates, extremely low latency, high reliability, fully connected coverage, and energy efficiency. Unmanned aerial vehicles (UAVs) are considered as promising new paradigm to the future of communications. However, limited battery capacity is a barrier to the effective spread of such solutions. Intelligent reflective surfaces (IRSs) that can reconFigure their reflection properties and electromagnetic absorption in real-time offer unparalleled opportunities to improve the wireless communication experience in difficult environments. In this respect, we highlight various use cases, research opportunities, and challenges for optimizing and designing wireless networks. Specifically, IRS carried by UAVs can meet important objectives in terms of future communications networks.
