Reference signal transmission method and apparatus therefor for location-based services in a wireless communication system

In the present application refer to a terminal position location in a wireless communication system signal, a method of detecting the (Location Based Service-Reference Signal below LBS-RS) is disclosed. Specifically, the mobile station receives the RS-LBS setting information for one or more target cells involved in the location measurement from the serving cell, using the RS-LBS setting information to obtain a frequency offset value of the target cell. Then, by using the LBS-RS configuration information and the frequency offset value, the detects the said LBS-RS transmitted from the target cell, and measures the reception delay time of the detected LBS-RS, the reception delay time and transmits the serving cell. Position location reference signal, the pilot pattern, OTDOA
