In the fifth generation (5G) of wireless communication systems, hitherto unprecedented
requirements are expected to be satisfied. As one of the promising techniques of addressing …

Non-orthogonal multiple access techniques have been proposed recently for 5G wireless
systems and beyond to improve access efficiency by allowing many users to share the same …

In this paper, we study the resource allocation and user scheduling problem for a downlink
non-orthogonal multiple access network where the base station allocates spectrum and …

As a promising downlink multiple access scheme for future radio access (FRA), this paper
discusses the concept and practical considerations of non-orthogonal multiple access …

Non-orthogonal multiple access (NOMA) has been recognized as a promising multiple
access technique for the next generation cellular communication networks. In this paper, we …

In this paper, we propose a non-orthogonal multiple access-based multiuser beamforming
(NOMA-BF) system designed to enhance the sum capacity. In the proposed NOMA-BF …

Multicast beamforming with superposition coding (SC) is studied for multiresolution
broadcast where both data streams of high priority (HP) and low priority (LP) are to be …

Using the theory of Poisson cluster process (PCP), this paper provides a framework to
analyze multi-cell uplink non-orthogonal multiple access (NOMA) systems. Specifically, we …

In this paper, we consider a massive grant-free non-orthogonal multiple access (GF-NOMA)
scheme, where devices have strict latency requirements and no retransmission …

This paper addresses the issues related with conventional near–far user pairing in non‐
orthogonal multiple access. Performance effects of near–far pairing on regions with …
