论文摘要
这封信研究了如何使用在传统空间分区多访问（SDMA）网络中预先配置的空间束作为带宽资源，这是通过实施非正交多重访问（NOMA）的带宽资源。开发了两种不同的光束管理方案，即光束选择和光束聚集，以改善整体系统吞吐量而不消耗额外的频谱或改变旧网络的性能。提出了分析和仿真结果，以表明这两个方案实现了系统性能和复杂性之间的不同权衡。
This letter studies how to use spatial beams pre-configured in a legacy spatial division multiple access (SDMA) network as bandwidth resources via the implementation of non-orthogonal multiple access (NOMA). Two different beam management schemes, namely beam selection and beam aggregation, are developed to improve the overall system throughput without consuming extra spectrum or changing the performance of the legacy network. Analytical and simulation results are presented to show that the two schemes realize different tradeoffs between system performance and complexity.
