Method and apparatus for estimating geo-location of terminal in wireless communication system

The present invention, the radio that the method from the system to the MS operation method for providing geographic location information, the initial ranging information to obtain an initial ranging code to a method and apparatus for estimating a geographical position of a terminal in a wireless communication system by the including the step and the step of the method comprising the steps of: receiving a second ranging resource allocated from the BS and transmitting the second ranging code transmitted to the base station, geographical location that has not equipped with GPS capability terminal during a ranging procedure It has the advantage that you can get the information. In addition, it is possible to make a reliable estimate of the geographic location of the terminal that does not have the GPS function. Cognitive Radio (Cognative Radio: CR), GPS, geographic location, ranging, distance estimation.
