Abstract
Aerial access networks have been envisioned as a promising 6G solution to enhance the ground communication systems. To better utilize the spectrum and fully explore different channel characteristics, this paper constructs an integrated network comprising the high altitude platform (HAP) and unmanned air vehicles (UAVs) with the non-orthogonal multiple access (NOMA) technology. In order to improve the transmission quality of the images and videos, a power management scheme is proposed to minimize the distortion of the transmissions from the HAP and UAVs to the terminals. The power control is formulated as a non-convex problem. The variable substitution and the first-order Tailors expansion is used to transform it into a sequence of convex problems, which are subsequently solved through Lagrangian dual method. Simulation demonstrates the signal distortion improvement achieved by the proposed scheme.
