在这封信中，我们给出了第一次尝试，以获得的好处，非正交多址接入（NOMA）纳入小小区网络（SCN）与混合自动重传请求（HARQ）。结合计划NOMA-SCN的中断性能进行了彻底的调查下，I型HARQ存储和不存储。通过使用随机几何，我们推导出封闭形式的中断概率的近，远NOMA用户。仿真结果与理论分析完全一致。此外，在NOMA-SCN中，有存储的HARQ比没有存储的HARQ具有更好的中断性能。
In this letter, we give the first attempt to reap the benefits of non-orthogonal multiple access (NOMA) incorporated in small cell networks (SCNs) with hybrid automatic repeat request (HARQ). The outage performance of the incorporated scheme NOMA-SCN is investigated thoroughly under Type I HARQ with and without storage. By using stochastic geometry, we derive closed-form outage probabilities of near and far NOMA users. Simulation results are shown to be completely agreeable with the theoretical analyses. Besides, the HARQ with storage achieves a better outage performance than that without storage in the NOMA-SCN.
