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 …

In this paper, we investigate an underlay cognitive non-orthogonal multiple access (NOMA)-
based coordinated direct and relay transmission network with imperfect successive …

This paper investigates the application of non-orthogonal multiple access (NOMA) in a
coordinated direct and relay transmission (CDRT) system, where the base station (BS) …

This article investigates the outage performance of a wireless powered cooperative
nonorthogonal multiple access-based coordinated direct and relay transmission (CDRT) …

Non‐orthogonal multiple access (NOMA) is recognised as an improved multiple access
technique as compared with OMA technique to fulfil the requirements of fifth‐generation …

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 …

This article proposes a simultaneous wireless information and power transfer (SWIPT)-
enabled Internet of Things (IoT)-based cognitive nonorthogonal multiple access (NOMA) …

In this letter, the outage performance of a satellite-assisted cooperative non-orthogonal
multiple access (NOMA) system is studied, where a terrestrial source communicates with …

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 …

In hybrid device-to-device (D2D) and cellular networks, the cross interference between
different communication systems severely limits the system performance. Fortunately, non …
