Published in 2022 at "IEEE Transactions on Wireless Communications"

DOI: 10.1109/twc.2022.3195532

Abstract: In this paper, we propose two novel cooperative-non-orthogonal-multiple-access (C-NOMA) and cooperative-rate-splitting-multiple-access (C-RSMA) schemes for uplink user cooperation. At the first mini-slot of these schemes, each user transmits its signal and receives the transmitted signal of… read more here.
