TL;DR: It is shown that the downlink NOMA with SIC improves both the capacity and cell-edge user throughput performance irrespective of the availability of the frequency-selective channel quality indicator (CQI) on the base station side.

TL;DR: NOMA can be expected to efficiently exploit the near-far effect experienced in cellular environments and offer a better tradeoff between system efficiency and user fairness than orthogonal multiple access (OMA), which is widely used in 3.9 and 4G mobile communication systems.

TL;DR: In this article, a base station includes means configured to manage frequency blocks, means configured for assigning one or more resource blocks to a communication terminal being in a good channel state, means configurable to generate a control channel including the scheduling information for each frequency block, and means configured with frequency multiplexing control channels within the system frequency band and to transmit it.

TL;DR: This paper investigates the system-level throughput of non-orthogonal access with a successive interference canceller (SIC) in the cellular downlink assuming proportional fair (PF)-based radio resource (bandwidth and transmission power) allocation and proposes and compares three power allocation strategies among users.

TL;DR: Simulation results show that the proposed non-orthogonal access scheme with random beamforming and the intra-beam SIC simultaneously achieves better sum and cell-edge user throughput compared to orthogonalAccess, which is assumed in LTE-Advanced.
