需要说明的是，低功耗唤醒接收机/唤醒信号(Low power wake up receiver/wake-up signal，LP WUR)的基本工作原理为接收端包含第一模块和第二模块，第一模块为主通信模块，用来接收发送端传输的通信数据和发送通信数据，第二模块为低功耗模块，用来接收发送端发送的低功耗唤醒信号和低功耗信标信号，低功耗唤醒信号用来唤醒接收端主通信模块，低功耗信标信号用来为接收低功耗唤醒信号提供时间参考信息和其他信息，还可 以提供唤醒链路管理。如图3所示，第一模块未被第二模块唤醒时一直处于关闭状态，不发送接收数据，当有下行数据到达，第二模块检测到发送端发送的唤醒信号，且该唤醒信号包含本终端信息，则第二模块触发第一模块由关闭状态切换到工作状态，进行数据接收和发送。第二模块可以连续开启，或不连续开启，第二模块开启时可接收低功耗唤醒信号和低功耗信标信号。
NR系统可引入低功耗唤醒模块/接收机以及低功耗唤醒信号，终端空闲时可以关闭主通信模块/接收机或将其设置成深睡眠状态，仅通过低功耗唤醒模块/接收机来监听低功耗唤醒信号，从而实现降低终端功耗目的。主通信模块/接收机被唤醒，需要检测SSB以获取下行时间信息以及AGC调整，时频跟踪，CFO补偿等，主通信模块/接收机在关闭或处于深睡眠状态时无法维持精确的时间信息，因此在醒来后无法判断SSB的时域位置，需要在至少一个SSB burst set周期内盲检测SSB，功耗较大。
