This paper proposes a novel hybrid downlinkuplink cooperative NOMA (HDU-CNOMA)
scheme to achieve a better tradeoff between spectral efficiency and signal reception …

In this article, a novel two-phase transmission protocol is proposed to help the bidirectional
transmission in a user-aid two-way cooperative nonorthogonal multiple access system …

This paper investigates a two-way relay non-orthogonal multiple access (TWR-NOMA)
system, where two groups of NOMA users exchange messages with the aid of one half …

We investigate the problem of antenna selection (AS) in full-duplex (FD) cooperative non-
orthogonal multiple access (NOMA) systems, where a multi-antenna FD relay assists …

Recent studies have demonstrated the superiority of non-orthogonal multiple access
(NOMA) over orthogonal multiple access (OMA) in cooperative communication networks. In …

Nonorthogonal multiple access (NOMA) with successive interference cancellation is
considered as one of the most promising schemes in multi-user access wireless networks …

In this paper, we consider non-orthogonal multiple access (NOMA) relaying networks, where
one base station communicates with two mobile users with the aid of multiple relays. We …
