Aiming at a better tradeoff between the system frequency efficiency measured by the mean user throughput and the user fairness measured by the cell-edge user throughput, we propose applying fractional frequency reuse (FFR) and weighted proportional fair (PF)-based multiuser scheduling to non-orthogonal access with a successive interference canceller (SIC) in the cellular downlink. We also propose...
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. The purpose of this study is to examine the possibility of applying non-orthogonal access with a SIC to the systems beyond the 4G (thus IMT-Advanced) cellular...
This paper investigates the enhancement of cell-edge user throughput by using non-orthogonal access with a successive interference canceller (SIC) in the cellular uplink compared to orthogonal access, which is widely used in 3.9 and 4G mobile communication systems. Since both the total user throughput and cell-edge user throughput are important in a real system, we compare the cell-edge user throughput,...
