Cooperative Non-Orthogonal Multiple Access in 5G Systems
, 2015 Non-orthogonal multiple access (NOMA) has recently received considerable attention as a promising candidate for 5G systems. A key feature of NOMA is that users with better channel conditions have prior information about the messages of the other users ...

Resource Allocation and Performance Analysis of Hybrid RSMA-NOMA in the Downlink [PDF]
arXiv, 2023 Rate splitting multiple access (RSMA) and non-orthogonal multiple access (NOMA) are the key enabling multiple access techniques to enable massive connectivity. However, it is unclear whether RSMA would consistently outperform NOMA from a system sum-rate perspective, users' fairness, as well as convergence and feasibility of the resource allocation ...

Non-Orthogonal Multiple Access for FSO Backhauling
, 2017 We consider a free space optical (FSO) backhauling system which consists of two base stations (BSs) and one central unit (CU). We propose to employ non-orthogonal multiple access (NOMA) for FSO backhauling where both BSs transmit at the same time and in ...

A Survey of NOMA for VLC Systems: Research Challenges and Future Trends
Italian National Conference on Sensors, 2022 Visible light communication (VLC) has become a promising technology for high data rate communications and an attractive complementary to conventional radio frequency (RF) communication. VLC is a secure, energy efficient and cost-effective technology that

Resource allocation for integrated satellite‐terrestrial networks based on RSMA
IET Communications, EarlyView.We first establish a downlink transmission framework for the integrated satellite‐terrestrial network based on RSMA, to achieve high data rate transmission of virtual reality applications globally. Then, considering some practical constraints, a joint resource allocation problem of rate and transmission power is formulated.

On the Performance Gain of NOMA over OMA in Uplink Communication Systems
, 2019 In this paper, we investigate and reveal the ergodic sum-rate gain (ESG) of non-orthogonal multiple access (NOMA) over orthogonal multiple access (OMA) in uplink cellular communication systems. A base station equipped with a single-antenna, with multiple
