Meanwhile, in New Radio, Vehicle to Everything (V2X) has been proposed as a promising issue in the 3^rd.一代合作项目（3GPP）。本文研究了具有功率控制策略的资源分配机制，可以充分利用基于NOMA的车辆在车辆（V2V）通信系统中的车辆的移动特性。首先，通过光谱聚类根据其移动特性进行分组车辆。然后，在同一组中的车辆与NOMA策略分配相同的无线资源。为高速公路和城市情景而设计了两种分组方法。此后，基于利用Q-Learning的功率控制策略的结果来调整车辆的传输功率。仿真结果表明，与基于能量感应的资源分配方法相比，可以显然改善了V2V系统在分组接收的比率（PRR）方面的性能。SN - 1574-017X UR - HTTPS：//Doi.org/10.1155/2020/8811067 Do - 10.1155 / 2020/8811067 JF - 移动信息系统PB - Hindawi KW - ER -
