Link Budget Analysis for Dual-Steering-Based Ground-to-Air and Satellite-to-Air Communications in 6G Networks

IEEE Access
With the advent of 6G systems, non-terrestrial networks (NTNs) are emerging as a cornerstone for global, uninterrupted connectivity. This study evaluates the downlink link budget in a dual-steering TN–NTN architecture, where an aerial user ...
