In this study, non‐orthogonal multiple access (NOMA)‐based coordinated direct and relay
transmission (CDRT) is considered, where a base station (BS) directly communicates with …

In this article, we propose a downlink non-orthogonal multiple access (NOMA) based
coordinated direct and relay system with one cell-center user and multiple cell-edge users …

This paper studies the coordinated direct and relay transmission (CDRT) in the non-
orthogonal multiple access network, which consists of a base station (BS), a cell-center user …

Coordinated direct and relay transmission (CDRT) is a promising strategy to extend cell
coverage. However, higher spectral efficiency (SE) cannot be guaranteed in CDRT due to …

A coordinated direct and relay transmission is proposed using uplink non-orthogonal
multiple access (UP-NOMA). A two-user UP-NOMA scenario is considered, where a cell …

Non-orthogonal multiple access (NOMA) is a promising spectrally-efficient multiple access
technique for the fifth generation (5G) wireless networks. In this paper, we propose a …

In this paper, we investigate the performance of the non‐orthogonal multiple access (NOMA)
system with incremental relaying, where the relay is employed with amplify‐and‐forward …

In this paper, we study the performance improvement methods for a cell-edge user of two-
user non-orthogonal multiple access (NOMA) systems in downlink scenarios. To this end …

Non‐orthogonal multiple access (NOMA) has been proposed as a promising technique for
