This paper addresses the challenge of broadcast and unicast convergence by proposing a PHY/MAC (Physical Layer/Medium Access Control) architecture for 5G New Radio (NR). The solution is based on Power domain Non Orthogonal Multiple Access (P-NOMA). The main PHY/MAC configuration parameters have been analyzed theoretically and their impact on the service configurations is presented in this manuscript. The system concept has been translated into a prototype model and different evaluation tests are presented. First, simulations show that the PHY layer performs better than Time Division Multiplexing/Frequency Division Multiplexing (TDM/FDM) choices of current broadband access systems. Second, performance tests using a network simulation tool are described. The results for capacity, latency and reliability demonstrate that the proposed solution offers an excellent broadcast/unicast convergence choice with significant gain values with respect to legacy PHY/MAC alternatives.

使用 NOMA 实现 5G 网络中的广播/单播融合

本文通过提出适用于 5G 新无线电 (NR) 的 PHY/MAC(物理层/媒体访问控制)架构来解决广播和单播融合的挑战。该解决方案基于功率域非正交多址 (P-NOMA)。主要 PHY/MAC 配置参数已在理论上进行了分析,并在本手稿中介绍了它们对服务配置的影响。系统概念已转化为原型模型,并提出了不同的评估测试。首先,仿真表明 PHY 层的性能优于当前宽带接入系统的时分复用/频分复用 (TDM/FDM) 选择。其次,描述了使用网络模拟工具的性能测试。容量的结果,
