Abstract

本发明公开了一种SFN指示方法、终端设备、定位服务器和系统，涉及通信领域，用于解决检测相位旋转序列时由于无法区分相位旋转造成的误判。SFN指示方法包括：定位服务器获取小区i的SFN偏移指示参数；定位服务器将小区i的SFN偏移指示参数发送给终端设备；终端设备从定位服务器接收小区i的SFN偏移指示参数；终端设备获取小区j的无线帧n的帧号；终端设备根据小区j的无线帧n的帧号与小区i的SFN偏移指示参数确定小区i的相位旋转参数，或者，得到小区i的无线帧m上的窄带定位参考信号NPRS所使用的序列初始化因子，并根据小区i的序列初始化因子得到小区i的无线帧m上的NPRS。本发明的实施例应用于OTDOA定位。
