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.

Abstract: A method for implementing transmit diversity in a wireless mobile communication system adopting an SC-FDMA scheme is provided. A sequence of modulation symbols output from a DFT block are precoded prior to IFFT. The precoding is performed independently on an antenna basis. Modulation symbols mapped to each subcarrier of an SC-FDMA symbol, to be transmitted through each antenna may be additionally phase-shifted.
