This paper investigates the performance of a new framework for low-outage downlink non-
orthogonal multiple access (NOMA) using a coordinated direct and relay transmission …

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 …

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 …

This paper investigates a multi-hop decode-and-forward (DF) relay-aided non-orthogonal
multiple access (MH-DF-R-NOMA) scheme. The model overcomes the problems associated …

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 …

Non-orthogonal multiple access (NOMA) is regarded as a candidate radio access technique
for the next generation wireless networks because of its manifold spectral gains. A two …

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 …

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 …

Non-orthogonal multiple access (NOMA) is one of the key technologies to serve in ultra-
dense networks with massive connections which is crucial for Internet of Things. Besides …

Relays have been deployed to provide connectivity to heavily blocked and isolated radio
environments, but suffer from severe data rate losses due to the half-duplex nature of relays …
