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。
