摘要

This paper proposes an angular speed 3D-based beam tracking method using hybrid beamforming. We propose a new beam tracking algorithm that enables dynamic pilot insertion based on closed loop feedback control by utilizing the Line of Sight (LoS) path of the channel between T-BS and UAV-UE. Simulations show that the proposed beam tracking method has improved overall performance in terms of beamforming gain and spectral efficiency (SE).
