第三代合作组织项目(Third Generation Partnership Project，3GPP)网络协议至少可包括4G长期演进(Long Term Evolution，LTE)网络协议和5G新空口(New RAT，NR)网络协议。其中，终端设备比如用户设备(User Equipment，UE)的4G LTE协议栈可包括：包数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路控制(Radio Link Control，RLC)层、MAC层和物理(Physical，PHY)层；而UE的5G NR协议栈可包括：服务数据适配协议(Service Data Adaptation Protocol，SDAP)层、PDCP层、RLC层、MAC层和PHY层。
