| Abstract(in English) | This paper presents the link level simulation results of downlink non-orthogonal multiple access (NOMA) with Open-Loop SU (Single-user)-MIMO and successive interference canceller (SIC). In the simulations, we apply the Open-Loop SU-MIMO based on the LTE (Long Term Evolution) Transmission Mode 3 (TM3) for 2-by-2 transmission and the number of multiplexed UE is two. And we clarify the performance of NOMA with codeword level SIC (CWIC) for the cell center user equipment (UE) and the performance of the cell edge UE, which does not apply SIC. Based on the link level simulations, we show that for cell-center UE the required SNR for achieving BLER of 10^<-1> is increased compared to that of Ideal SIC when the allocated transmission power ratio of cell center UE is larger due to the increase of inter user interference and inter stream interference. We also show that the increase of required SNR compared to that of Ideal SIC is smaller due to the increase of required SNR of cell center UE when we apply higher order modulation on cell center UE, and thus the effective allocated power ratio can be increased. However, for cell-edge UE, we show that we need to set up its transmission power ratio and MCS (Modulation and Coding Scheme) according to the required SNR and transmission rank in order to ensure its correct decoding at the cell-edge UE receiver. |
