Abstract

本发明实施例公开了一种时钟同步的方法及设备，涉及通信技术领域，可以解决由于AP发送给STA的同步帧中携带信息较大，而WUR醒来窗口的时长有限，导致该同步帧无法正常传输的问题。具体方案为：AP每隔第一时间向STA发一次至少一个WUR帧，至少一个WUR帧中的每个WUR帧中包含帧类型信息，帧类型信息用于指示该WUR帧为同步帧，第一时间小于临界时间、且第一时间大于WUR醒来窗口的间隔时间，临界时间为STA和AP发生时钟漂移使WUR醒来窗口与AP预计的所述STA的WUR醒来窗口完全错开所需的时间；AP在发送至少一个WUR帧时，将AP的TSF时钟序列设置为第一预定义值。本发明用于AP和STA进行时钟同步的过程中。
