The non-orthogonal multiple access (NOMA) schemes, where the users are allowed to
share the same time-frequency resource, have recently received a major interest to meet the …

Power allocation plays an important role in cooperative non-orthogonal multiple access
(NOMA) systems. To guarantee the quality of service (QoS) requirements of users, we …

Power allocation is an important issue in order to optimize the performance of non-
orthogonal multiple access (NOMA) systems. However, the power allocation problem for …

In this paper, we propose bi-directional cooperative non-orthogonal multiple access
(NOMA). Compared to conventional NOMA, the main contributions of bi-directional …

NOMA is a promising radio access technique for next-generation wireless networks. In this
article, we investigate the NOMA-based cooperative relay network. We begin with an …

In conventional cooperative non-orthogonal multiple access (NOMA) networks, spectral
efficiency loss occurs due to a half-duplex constraint. To address this issue, we propose an …

In this paper, we propose a two-way cooperative relay scheme based on non-orthogonal
multiple access (NOMA) where bidirectional communication is supported for two users in …

In this work, a novel time and relay shared (TRS) based full/half duplex (FD/HD) cooperative
non-orthogonal multiple access (C-NOMA) scheme namely TRS FD/HD C-NOMA is …

In this paper, a novel cooperative non-orthogonal multiple access (NOMA) system is
proposed, where one near user is employed as decode-and-forward relaying switching …

There is a huge demand for increased connectivity and reliability of devices in the fifth
generation and beyond of wireless communications so as to ensure massive connectivity …
