Abstract

UAV-to-ground (U2G) wireless communication has emerged as a key enabler for next-generation networks due to its flexible deployment and improved line-of-sight (LoS) conditions. However, existing models lack integration of third dimension (3D) parameters, UAV altitude and orientation, for different urban environments. To address this gap, we propose a 3D time-varying U2G path loss (PL) that includes UAV altitude and orientation. The proposed model derives mathematically the accuracy of multipath delay and amplitude estimation using altitude and orientation characteristics. The proposed model approach applies extended parametric formulation using simulation analysis. Simulation results demonstrate that the proposed model achieves up to a 4.5% improvement in multipath delay estimation accuracy and a 3% reduction in PL error compared to existing models.
