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 …

Non-orthogonal multiple access (NOMA) is one of the promising radio access techniques in
5G communication networks. In this paper, a cooperative NOMA relaying scheme with two …

In this article, we investigate a selective decode-and-forward (DF)-aided cooperative
nonorthogonal multiple access (NOMA) system performance in the presence of practical …

Non-orthogonal multiple access (NOMA) is a promising technique for the fifth generation
(5G) wireless communications. As users with good channel conditions can serve as relays to …

This letter presents a new downlink cooperative non-orthogonal multiple access (NOMA)
transmission scheme to serve three users within only two time slots. The scheme involves a …

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 …

In this paper, we investigate a non-orthogonal multiple access (NOMA) assisted multi-
antenna two-way relay system, where multi-antenna users apply NOMA to support …

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 conventional cooperative non-orthogonal multiple access (NOMA) networks, spectral
efficiency loss occurs due to a half-duplex constraint. To address this issue, we propose an …

Non-orthogonal multiple access (NOMA) is a promising radio access technique for 5th
generation (5G) communication systems. In order to enhance the performance of NOMA …
