Non-orthogonal multiple access (NOMA) has been widely recognized as a promising
multiple access scheme for realizing next generation wireless communications. Unlike …

In this work, we investigate the effect of time asynchrony in non-orthogonal multiple access
(NOMA) schemes for downlink transmissions. First, we analyze the benefit of adding …

In this work, we derive closed-form expressions for the throughput of non-orthogonal
multiple access (NOMA) and use the expressions to maximize the throughput. The design …

To achieve an efficient and reliable data transmission in time-varying conditions, a novel
non-orthogonal multiple access (NOMA) transmission scheme based on rateless codes …

In this paper, the concept of grantfree non-orthogonal multiple access (NOMA) for uplink
data transmission is elaborated. NOMA in combination with grant-free can be applied to ultra …

In this article, we investigate the latency performance of non-orthogonal multiple access
(NOMA) and orthogonal multiple access (OMA) technologies in finite blocklength regime. In …

In fifth-generation mobile communications systems (5G), grant-free non-orthogonal multiple
access (NOMA) schemes have been considered as a way to accommodate the many …

This correspondence paper considers nonorthogonal multiple access (NOMA)-assisted
slotted ALOHA (NOMA-ALOHA) for machine-type communications. NOMAALOHA is a hybrid …

Non-orthogonal multiple access (NOMA) has been proposed as an alternative to orthogonal
multiple access (OMA) in an effort to enhance the spectral efficiency of 5G cellular systems …

To improve the utilization of spectrum and system capacity, non-orthogonal multiple access
(NOMA) is considered as a promising multiple access method for emerging communication …
