In this paper, we study the application of opportunistic non-orthogonal multiple access
(NOMA) mode to short-message transmissions with user's power control under a finite …

The antenna selection (AS) in non-orthogonal multiple access (NOMA) networks is still a
challenging problem since finding optimal AS solution may not be available for all channel …

In this paper, we propose to utilize multiple aerial intelligent reflecting surfaces (AIRSs) for
significantly enhancing the ergodic capacity of a non-orthogonal multiple access (NOMA) …

Contention based uplink (CB UL) access has been proposed as an effective way to simplify
uplink access signaling interactions and reduce access latency compared with traditional …

In this paper, an energy harvesting enabled cooperative non-orthogonal multiple access
(NOMA) system for a multi-cell network is investigated. Particularly, during the direct …

The future sixth generation (6G) is going to face the significant challenges of massive
connections and green communication. Recently, reconfigurable intelligent surfaces (RIS) …

This article investigates the performance of reconfigurable intelligent surface assisted two-
way non-orthogonal multiple access (RIS-TW-NOMA) networks, where a pair of users …

NOMA has been recognized as a highly promising FRA technology to satisfy the
requirements of the fifth generation era on high spectral efficiency and massive connectivity …

Nonorthogonal multiple access (NOMA) is seen as an important technology for tomorrow's
Internet-of-Things (IoT) systems. In uplink power-domain NOMA (PD-NOMA), allocating the …

This paper proposes a new communication protocol for a cooperative non-orthogonal
multiple access (NOMA) system. In this system, based on users' channel conditions, each …
