摘要
In this paper, a resource allocation scheme, SCMA-Hungarian (SH), for downlink SCMA system is proposed. By jointly considering the fairness and the guaranteed bit rate (GBR) constraint, Hungarian method is used to achieve a global best assignment, aiming to make more users meeting GBR requirement with high fairness. To further reduce the computation complexity, the Block-based SCMA-Hungarian (BSH) scheme is proposed for practical scenario. Simulation results demonstrate that BSH and SH have similar performance. The two schemes outperform in both throughput by nearly 8.5% and the number of users meeting GBR requirement by maximum 15.6% compared to an existing fairness scheme, SCMA-PF.
