    • The present invention relates to a repeater for positioning mobile station and a method thereof. The repeater according to the present invention is implemented through adding a cell identifier generator module to the downlink circuit structure of a conventional repeater; said cell identifier generator module includes: a synchronization searching unit designed to search for base station synchronization signal, a time delay unit designed to generate a fixed delay between start time of cell identifier signal frame and start time of base station pilot signal frame, and a cell identifier signal generating unit designed to generate cell identifier signal code word. The mobile station positioning method determines the mobile station is in the coverage of the repeater on the basis that the time difference between base station pilot signal and cell identifier signal is consistent to the fixed delay; then the method utilizes TOA (Time of Arrival) measuring function to determine the distance from the mobile station to the repeater; thus it improves positioning accuracy of mobile stations in the coverage of the repeater. The repeater for positioning mobile station is easy to implement and can meet the positioning requirement of a plurality of mobile stations in the coverage of the repeater.
    • 本发明涉及一种用于定位移动台的中继器及其方法。 根据本发明的中继器通过将小区标识符生成器模块添加到常规中继器的下行链路电路结构来实现; 所述小区标识符发生器模块包括:设计用于搜索基站同步信号的同步搜索单元,设计成在小区标识符信号帧的开始时间和基站导频信号帧的起始时间之间产生固定延迟的时间延迟单元,以及 小区标识符信号生成单元,用于生成小区标识信号码字。 移动台定位方法基于基站导频信号与小区标识符信号之间的时差与固定延迟一致,确定移动台处于中继器的覆盖范围内; 那么该方法利用TOA(到达时间)测量功能来确定从移动台到中继器的距离; 从而提高了移动台在中继器覆盖范围内的定位精度。 用于定位移动台的中继器易于实现,并且可以满足中继器覆盖范围内的多个移动台的定位要求。
