| Abstract(in English) | Aiming at the better tradeoff between the system frequency efficiency measured by the average user throughput and user fairness measured by the cell-edge user throughput, we consider the combination of fractional frequency reuse (FFR) and non-orthogonal access with a successive interference canceller (SIC) in the cellular downlink. We propose a frequency block access policy for cell-interior and cell-edge user groups in FFR and proportional fair (PF)-based multiuser resource (bandwidth and transmission power) allocation, which are appropriate for the non-orthogonal access with SIC. The extensive simulation results show that the combination of the FFR and non-orthogonal access with SIC significantly enhances the system-level throughput performance compared to orthogonal access, which is widely used in 3.9 and 4G mobile communication systems. |
