Abstract(in English) | This paper investigates the system-level throughput performance of the non-orthogonal access with minimum mean squared error-based liner filtering followed by the successive interference canceller (MMSE-SIC) in the cellular uplink. Although the non-orthogonal access with MMSE-SIC can achieve the multiuser capacity region in the multiple access channel (MAC), which should be beneficial to enhance the total user throughput and cell-edge user throughput simultaneously compared to the orthogonal access, the multiplexing of multiple users within the same frequency block may increase the inter-cell interference in the context of the cellular uplink. The aim of the transmission power control investigated in the paper is to mitigate the inter-cell interference increase due to non-orthogonal user multiplexing. Regarding the multiuser scheduling, we employ a proportional fair (PF)-based one to achieve a good tradeoff between the total user throughput and cell-edge user throughput. The simulation results show that non-orthogonal access with MMSE-SIC using the proposed transmission power control significantly enhances the system-level throughput performance compared to orthogonal access, which is widely used in 3.9 and 4G mobile communication systems. |
