In this work, two signal-space diversity (SSD) based schemes are proposed for a system
where one user is directly in contact with both the base station and the relay, while the other …

In this work, non-orthogonal multiple access (NOMA) in coordinated direct and relay
transmission (CDRT) is introduced, where a base station (BS) directly communicates with …

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 paper, an uplink scheme that exploits cooperative diversity using power domain
nonorthogonal multiple access (NOMA), termed UCD‐NOMA, with successive interference …

This paper has investigated a downlink non-orthogonal multiple access (NOMA) cooperative
scheme with user-assisted relaying, where near users are viewed as decode-and-forward …

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 …

We propose a spectral-efficient coordinated direct and relayed transmission (CDRT) scheme
for a relay-assisted downlink system with a near user and a far user. The proposed scheme …

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 …

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 …

This article investigates the outage performance of a novel two-user multi-relay non-
orthogonal multiple access (NOMA)-based hybrid satellite-terrestrial relay network (HSTRN) …
