Method for transmitting location based service-reference signal in wireless communication system and apparatus therefor

摘要

A method for allowing a mobile station to detect a Location Based Service-Reference Signal (LBS-RS) in a wireless communication system is disclosed. The method includes receiving LBS-RS setup information of at least one target cell participating in location measurement from a serving cell, acquiring a frequency offset value of the target cell using the LBS-RS setup information, and detecting the LBS-RS transmitted from the target cell using the LBS-RS setup information and the frequency offset value. In addition, the method further includes measuring a reception delay time of the detected LBS-RS, and transmitting a reception delay time to the serving cell.

1. A method for receiving a positioning reference signal (PRS) at a mobile station in a wireless communication system, the method comprising:
receiving PRS configuration information from a network; receiving the PRS from at least one neighbor cell participating in location measurement; and performing the location measurement using the PRS, wherein the PRS configuration information includes one or more fields for the at least one neighbor cell if each of the one or more fields is not the same for a cell that is a reference of the location measurement, and wherein the one or more fields indicate a bandwidth of the PRS, a cyclic prefix (CP) length and a number of transmission antennas.
