Angle Feedback for NOMA Transmission in mmWave Drone Networks

IEEE Journal of Selected Topics in Signal Processing, 13(3), 628–643.

By: N. Rupasinghe n, Y. Yapici n, I. Guvenc n, M. Ghosh & Y. Kakishima

author keywords: 5G; drone; HPPP; mmWave; non-orthogonal multiple access (NOMA); stadium; UAV
TL;DR: It is shown that as the user region for NOMA transmission gets wider, the users become more distinctive at the transmitter side with respect to their angles, making user angle feedback a better alternative than distance feedback in such scenarios. (via Semantic Scholar)
