A Wideband Scheduling Method for Non-Orthogonal Multiple Access in the Vienna LTE-A Downlink System-Level Simulator

Non-Orthogonal Multiple Access (NOMA) is a promising direction to meet the demand of high spectral efficiency. To fully utilize its advantage, an efficient scheduling method for multiuser selection is required. In this paper we propose a NOMA wideband scheduling method taking into account not only the user set and their power allocation but also the modulation and coding scheme. Furthermore, we introduce an extension of the open-source Vienna LTE-A downlink system-level simulator by implementing multi-user superposition transmission at the transmitter and successive interference cancelation at the receiver. Simulation results validate that the proposed scheduling method outperforms baseline methods.
