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

A base station apparatus for providing geo-location information of a terminal in a communication system, the apparatus comprising:

• a controller configured to receive a first ranging code from an access terminal in a network entry process and transmit information on a ranging resource to neighbor terminals of the access terminal;
• and
• a scheduler configured to allocate the ranging resource to the access terminal,
• wherein the controller is further configured to receive information indicating a distance between the access terminal and each neighbor terminal from the access terminal and the neighbor terminals.
