POSITION CALCULATION METHOD AND APPARATUS IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method of positioning a mobile station (MS) in a wireless communication system, the method being performed by the MS, the method comprising:
- receiving information on a reference signal for positioning from a serving base station;
measuring the reference signal;
comparing a transmission polarization characteristic and reception polarization characteristic of the measured reference signal and determining whether a light of sight (LOS) link between a base station for transmitting the reference signal and the MS is present or not, when the information on the reference signal includes information on the transmission polarization characteristic of the reference signal; and
transmitting information on whether the LOS link is present or not to the serving base station.

Abstract
A method of positioning a mobile station (MS) in a wireless communication system is provided. The method is performed by the MS. The method includes receiving information on a reference signal for positioning from a serving base station, measuring the reference signal, comparing a transmission polarization characteristic and reception polarization characteristic of the measured reference signal and determining whether a light of sight (LOS) link between a base station for transmitting the reference signal and the MS is present or not, when the information on the reference signal includes information on the transmission polarization characteristic of the reference signal, and transmitting information on whether the LOS link is present or not to the serving base station.

8. A method of positioning a mobile station (MS) in a wireless communication system, the method being performed by a base station, the method comprising:
-
transmitting, to a serving MS, information on a reference signal for positioning and information indicating whether to report a reception polarization characteristic of the reference signal; receiving information on the reception polarization characteristic of the reference signal from the serving MS; and comparing the reception polarization characteristic and a transmission polarization characteristic of the reference signal and determining whether a light of sight (LOS) between a base station which transmits the reference signal and the MS is present or not, or a possibility that the LOS link is established. - View Dependent Claims (9, 10)

11. A mobile station (MS) for positioning in a wireless communication system, the MS comprising:
-
a radio frequency (RF) unit; and a processor configured to control the RF unit, wherein the processor is configured to receive information on a reference signal for positioning from a serving base station, to measure the reference signal, to compare a transmission polarization characteristic and reception polarization characteristic of the measured reference signal to determine whether a light of sight (LOS) link between a base station for transmitting the reference signal and the MS is present or not, when the information on the reference signal includes information on the transmission polarization characteristic of the reference signal, and to transmit information on whether the LOS link is present or not to the serving base station. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A base station (BS) for positioning a mobile station (MS) in a wireless communication system, the BS comprising:
-
a radio frequency (RF) unit; and a processor configured to control the RF unit, wherein the processor is configured to transmit, to a serving MS, information on a reference signal for positioning and information indicating whether to report a reception polarization characteristic of the reference signal, to receive information on the reception polarization characteristic of the reference signal from the serving MS, and to compare the reception polarization characteristic and a transmission polarization characteristic of the reference signal to determine whether a light of sight (LOS) between a base station which transmits the reference signal and the MS is present or not or a possibility that the LOS link is established. - View Dependent Claims (19, 20)
