This paper investigates the performance of cooperative non-orthogonal multiple access
(NOMA) systems, where one near user works as a decode-and-forward (DF) full-duplex (FD) …

In this paper, we investigate a coordinated direct and relay transmission for uplink (CDRT-
UL) of a cooperative non-orthogonal multiple access (NOMA) system, in which two users …

It is challenging for the base station (BS) to serve multiple cell-edge users concurrently with
data rate guarantee due to limited power and spectrum resource. Using the relay enhances …

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

Non-orthogonal multiple access (NOMA) is a promising multiple access technique for the
fifth generation (5G) wireless communications. In order to enhance the performance gains of …

We investigate the beamforming for cooperative non-orthogonal multiple access (NOMA)
transmission through a decode-and-forward relay either with full-duplex (FD) mode or with …

Non-orthogonal multiple access (NOMA) is a promising technology in future communication
systems. In this paper, we propose a buffer-aided NOMA relaying system, which consists of …

Cooperative non-orthogonal multiple access (NOMA) systems inherit advantages of the
NOMA protocol and the cooperative relay. In this paper, we propose cooperative NOMA …

This paper investigates a cooperative non-orthogonal multiple access system, in which a
base station communicates with two far users with the aid of a decode-and-forward (DF) …

In order to improve the spectral efficiency, non-orthogonal multiple access (NOMA) with
superposition coding is employed in a coordinated system where downlink signals to users …
