Non-orthogonal multiple access (NOMA) has been recognized as a key driving technology
for the fifth generation (5G) and beyond 5G cellular networks. For a practical downlink …

User pairing in non-orthogonal multiple-access (NOMA) uplink is investigated considering
some predefined power allocation schemes. The base station divides the set of users into …

This article presents advances in resource allocation for downlink non-orthogonal multiple
access (NOMA) systems, focusing on user pairing and power allocation algorithms. The …

In this letter, we explore user pairing in a downlink non-orthogonal multiple access (NOMA)
network. As power allocation inherently intertwines with user pairing, a joint user pairing and …

Non-orthogonal multiple access (NOMA) is a promising multiple access technique for 5G
wireless technology. In this paper, we first discuss the fundamentals of uplink and downlink …

Optimizing non-orthogonal multiple access (NOMA) in multi-cell scenarios is much more
challenging than the single-cell case because inter-cell interference must be considered …

Conventional non-orthogonal multiple access (NOMA) schemes assume perfect channel
state information (CSI) at the transmitter side, which is nearly impractical for many …

Non-orthogonal multiple access (NOMA) is a potential enabler for the development of 5G
and beyond wireless networks. By allowing multiple users to share the same time and …

Non-orthogonal multiple access (NOMA) is widely recognized to increase the number of
users and enhance the spectral efficiency in fifth-generation (5G) wireless networks and …

In most existing works on non-orthogonal multiple access (NOMA), the decoding order of
successive interference cancellation (SIC) is prefixed and based on either the users' …
