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 …

The demand for massive connectivity and low latency in future wireless networks has
outlined the non-orthogonal multiple access (NOMA) scheme a key technology due to its …

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 …

Abstract In fifth-generation (5G) wireless communication systems, non-orthogonal multiple
access (NOMA) has been considered as a promising multiple access technique. In this …

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 …

Non-orthogonal multiple access (NOMA) has attracted great recent attention due to its high
spectral efficiency. Besides, NOMA can be easily implemented in physical layer, thus its …

Non-orthogonal multiple access (NOMA) has recently received much attention as a
candidate technique for the fifth generation networks. In this paper, considering both the …

Abstract Non-Orthogonal Multiple Access (NOMA) technology can accommodate more
subscribers concurrently and achieve higher spectrum efficiency than Orthogonal Multiple …

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 this article, we evaluate the overall outage probability (OOP) of pairwise Non-orthogonal
Multiple Access (NOMA) for both uplink and downlink. We also propose a dynamic decoding …
