Abstract

本发明实施例提供一种时间差获取方法，包括：所述第一基站接收所述用户设备对第二基站发送的第一下行数据的第一反馈信息；所述第一基站确定所述用户设备发出所述第一反馈信息的第一时间，并记录接收到所述第一反馈信息的第二时间；所述第一基站计算所述第二时间、从所述用户设备到所述第一基站的信息传输时长以及所述第一时间之间的时间差。应用本发明实施例提供的技术方案，基站间不需要安装GPS或1588V2等授时装置进行同步，也能按照载波聚合的要求进行通信，节省了产品成本。

An embodiment of the present invention provides a method for obtaining a time difference, including: the first base station receiving, by the first base station, first feedback information of the first downlink data sent by the user equipment to a second base station; the first base station determining the user equipment sending the first time of the first feedback information, and recording the second time of receiving the first feedback information; the first base station calculates the second time, from the user equipment to the first base station The information transmission duration and the time difference between the first time. By applying the technical solutions provided by the embodiments of the present invention, there is no need to install timing devices such as GPS or 1588V2 for synchronization between base stations, and communication can also be performed according to the requirements of carrier aggregation, which saves product costs.
