As a key candidate technique for fifth-generation (5G) mobile communication systems, non-
orthogonal multiple access (NOMA) has attracted considerable attention in the field of …

Grant-free non-orthogonal multiple access is an emerging research topic in machine-type
communications, which is used to reduce signaling overhead. In this context, this letter …

Nonorthogonal multiple access (NOMA) and multiple-input multiple-output (MIMO) are two
key enablers for 5G systems. In this article, considering the practical issue that successive …

Nonorthogonal multiple access (NOMA) has been considered as an essential multiple
access technique for enhancing system capacity and spectral efficiency in future …

In this letter, we propose a joint power and code-domain non-orthogonal multiple access
(NOMA) technique for the fifth-generation (5G) wireless networks and beyond. We consider …

Successive interference cancelation (SIC) has been considered widely for the detection of
downlink nonorthogonal multiple access (NOMA) signals. However, the sequential detection …

Non-orthogonal multiple access (NOMA) will provide massive connectivity for future Internet
of Things. However, the intrinsic non-orthogonality in NOMA makes it non-trivial to approach …

As a prominent member of the Next Generation Multiple Access (NGMA) family, Non-
Orthogonal Multiple Access (NOMA) has been recognized as a promising multiple access …

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' …

As a means to support the access of massive machine-type communication devices, grant-
free access and non-orthogonal multiple access (NOMA) have received great deal of …
