| Abstract(in English) | We consider an efficient precoding information feedback method for the non-orthogonal access with successive interference canceller (SIC) in cellular multiple-input multiple-output (MIMO) uplink assuming time division duplex (TDD). The proposed method is based on the eigenmode MIMO beamforming using singular value decomposition of the channel matrix considering the properties of the non-orthogonal access with SIC and channel reciprocity in TDD. Furthermore, in order to achieve effective power allocation to multiple data streams, we propose an inter-user interference power feedback-based waterfilling. From the simulation results, we show that the combination of the eigenmode MIMO-based beamforming and the interference power feedback-based waterfilling power allocation can achieve higher throughput compared to the conventional codebook-based precoding for a wide range of signal-to-noise ratio (SNR) and maximum Doppler frequency. |
