Non-orthogonal multiple access (NOMA) allows multiple users to simultaneously access the
same time-frequency resource by using superposition coding and successive interfer-ence …

We investigate the performance of a hybrid non-orthogonal multiple access (NOMA) multi-
cell downlink system (called hybrid as different users can have different successive …

In this technical note, we present a new theoretical result for multi-cell non-orthogonal
multiple access (NOMA). For multi-cell scenarios, a so-called load-coupling model has been …

The common approach in previous generations of cellular networks, from the 1G to 4G, has
been “orthogonality,” where distinct resource blocks, such as frequency, time, signature …

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 …

Non-orthogonal multiple access (NOMA) has recently been considered as a key enabling
technique for 5G cellular systems. In NOMA, by exploiting the channel gain differences …

-Non-orthogonal multiple access (NOMA) is a spectrum reutilization technique that
superposes messages in the power domain allowing multiple users to be served in the …

Non-orthogonal multiple access is a promising technology for the fifth generation systems
which exploits the power domain to achieve higher spectral efficiency. The performance of …

Non-orthogonal multiple access (NOMA) has received significant attention for future wireless
networks. NOMA outperforms orthogonal schemes, such as OFDMA, in terms of spectral …

The key idea of non-orthogonal multiple access (NOMA) is to achieve the channel capacity
of degraded broad-cast channels by a linear superposition coding combined with …
