Although the use of coordinated direct and relay transmission (CDRT) in non-orthogonal
multiple access (NOMA) can extend the coverage, its duplicated transmission reduces the …

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 …

In this letter, the performance of non-orthogonal multiple access (NOMA) with full-duplex
relaying is investigated in multi-user single-input single-output downlink systems. Contrary …

This letter puts forth a practical non-orthogonal multiple access (NOMA)-based coordinated
direct and relay transmission (CDRT) scheme, referred to as network-coded multiple access …

In this paper, a backscatter cooperation (BC) scheme is proposed for non-orthogonal
multiple access (NOMA) downlink transmission. The key idea is to backscatter the surplus …

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 …

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

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 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 …
