This paper designs a novel opportunistic adaptive non-orthogonal multiple access (OA-
NOMA) strategy, where a base station (BS) employs NOMA to serve a near user (NU)-far …

Non-orthogonal multiple access (NOMA) has recently been proposed as a key enabling
technology for the fifth generation (5G) wireless networks. Different from the existing works …

Being able to accommodate multiple simultaneous transmissions on a single channel, non-
orthogonal multiple access (NOMA) appears as an attractive solution to support massive …

A novel semantics-empowered two-user uplink non-orthogonal multiple access (NOMA)
framework is proposed for resource efficiency enhancement. More particularly, a secondary …

Uplink power domain non-orthogonal multiple access (NOMA) random access (RA) system
allows users to transmit their packet with one of target receive power (TRP) levels at the …

Compared to the traditional orthogonal multiple access, non-orthogonal multiple access
(NOMA) technology can achieve higher spectrum efficiency and support more massive …

In this work, we thoroughly analyze the rate-region provided by the asynchronous
transmission in multiple access channels (MACs). We derive the corresponding capacity …

In this article, we consider the massive nonorthogonal multiple access (NOMA) with a hybrid
automatic repeat request (HARQ) for short packet communications. To reduce the latency …

We investigate the effect of time asynchrony in non-orthogonal multiple access (NOMA) for
downlink transmission. First, we analyze the benefits of adding intentional timing offsets to …

The key idea of non-orthogonal multiple access (NOMA) assisted grant-free transmission is
to create pre-configured receive signal-to-noise ratio (SNR) levels that can be used to serve …
