Abstract
Unmanned Aerial Vehicle (UAV) air-to-ground communication plays a significant role in the integrated information network. Reconfigurable Intelligent Surface (RIS), a passive antenna array, is particularly well-suited for UAV applications. However, airflow induced UAV wobbling can significantly damage the performance of the RIS enabled beamforming. In this paper, we investigate a robust beamforming method that employs a Rotator-Aided RIS (R-RIS), introducing a novel approach to mitigating disturbances. The design problem is non-convex, prompting the proposal of a heuristic strategy that effectively decouples the original problem. The simulation results validate the effectiveness of the proposed scheme, highlighting its ability to enhance the beam stabilization.
