Abstract

本发明实施例提供了一种定时同步方法、装置、用户设备和通信系统，涉及通信领域，所述方法包括：第一基站向UE发送第一信令；UE向第二基站发送第二信令；第二基站向UE发送第三信令；UE向第一基站发送第四信令；第一基站根据发送和接收第一信令、第二信令、第三信令、第四信令的时间，获取第一基站和第二基站之间的定时偏差；第一基站或者第二基站采用定时偏差调整定时。本发明通过在两个基站和UE之间传输信令，根据信令的发送时间和接收时间确定两个基站之间的定时偏差，进而调整基站的定时，完成两个基站间的定时同步，从而避免了现有技术中采用同步参考信号进行定时同步，存在的接收同步参考信号与发送同步参考信号相互干扰的问题。
