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 …

Different from conventional mobile networks designed to optimize the transmission efficiency
of one particular service (eg, streaming voice/video) primarily, the industry and academia …

Multiple access technology plays an important role in communication systems, which can
enable different users to access the system efficiently and reliably. However, the …

In non-orthogonal multiple access (NMA) system, signal transmitter and receiver are jointly
optimized, so that multiple layers of data from more than one user can be simultaneously …

The anticipated 1000-fold increase in mobile data traffic over the next decade and the
explosion of new services and applications pose great challenges for the current orthogonal …

In this article, we propose an uplink hybrid multiple access scheme (HMAS) in order to
support a highly overloaded multiuser system. In HMAS, for a fixed K-orthogonal resources …

Multiple access (MA) is a crucial part of any wireless system and refers to techniques that
make use of the resource dimensions to serve multiple users/devices/machines/services …

Rate-Splitting Multiple Access (RSMA) has emerged as a powerful multiple access,
interference management, and multi-user strategy for next generation communication …

This paper summarizes the ongoing research initiatives based on the advanced multiple
access techniques towards the fifth generation (5G) wireless communication and beyond …

5G radio access networks are expected to provide very high capacity, ultra-reliability and
