US 8,274,959 B2 · Method for transmitting location based service—reference signal in wireless communication system and apparatus therefor

Abstract

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.

Dependent claims

A method for receiving positioning reference signals (PRSs) at a mobile station in a wireless communication system, the method comprising:

receiving PRS configuration information from a serving cell;
receiving the PRSs from the serving cell and at least one neighbor cell participating in location measurement;
and
performing the location measurement using the PRSs,
wherein the PRS configuration information includes information on at least one neighbor cell, and
wherein the information on the at least one neighbor cell includes fields indicating at least a bandwidth of a PRS, a cyclic prefix (CP) length of the PRS or a number of transmission antennas for the at least one neighbor cell.
