In this survey paper, we first provide insights on the evolution of radio access networks
(RANs) through investigating the existing paradigms and future trends towards 6G. We then …

Mathematical optimization is now widely regarded as an indispensable modeling and
solution tool for the design of wireless communications systems. While optimization has …

This article investigates several critical issues on the ergodic sum capacity and system
outage performance of downlink non-orthogonal multiple access (NOMA) systems with …

While non-orthogonal multiple access (NOMA) improves spectral efficiency, it adds
complexity to the receivers due to successive interference cancellation (SIC). Prior studies …

In this paper, we consider downlink power-domain non-orthogonal multiple access (NOMA)
