5G蜂窝通信系统的物理层旨在实现更好的灵活性，以支持多样化的服务和用户需求。利用灵活的多参数集结构丰富OFDM波形参数。本文从灵活性的角度描述了长期演进（LTE）系统和新无线电（NR）系统之间的差异。多命理学系统的研究机会以结构化的方式呈现。最后，通过仿真得到了作为保护分配和多参数集参数的函数的参数集间干扰（INI）结果。
The physical layer of 5G cellular communications systems is designed to achieve better flexibility in an effort to support diverse services and user requirements. OFDM waveform parameters are enriched with flexible multi-numerology structures. This paper describes the differences between Long Term Evolution (LTE) systems and new radio (NR) from the flexibility perspective. Research opportunities for multi-numerology systems are presented in a structured manner. Finally, inter-numerology interference (INI) results as a function of guard allocation and multi-numerology parameters are obtained through simulation.
