Abstract : Next generation wireless networks require massive uplink connections as well as high spectral efficiency. It is well known that, theoretically, it is not possible to achieve the sum capacity of multi-user communications with orthogonal multiple access. To meet the challenging requirements of next generation networks, researchers have explored non-orthogonal and overloaded transmission technologies–known as new radio multiple access (NR-MA) for fifth generation (5G) networks. In this article, we discuss the key features of the promising NRMA schemes for the massive uplink connections. The candidate schemes of NR-MA can be characterized by multiple access signatures (MA-signatures), such as codebook, sequence, and interleaver/scrambler. At the receiver side, advanced multiuser detection (MUD) schemes are employed to extract each user’s data from non-orthogonally superposed data according to MAsignatures. Through link-level simulations, we compare the performances of NR-MA candidates under the same conditions.
