BASE STATION MAPPING WITH ANGLE-OF-ARRIVAL AND TIMING ADVANCE MEASUREMENTS
摘要
<p>Methods and apparatus for determining a position estimate for a base station transceiver node in a wireless communication system are disclosed. Angle-of-arrival and/or timing advance measurements corresponding to transmissions received from mobile stations for which geographic locations are already known are combined with known locations for the mobile stations to estimate the position of the base station receiving the transmissions. This estimated base station position may be used, for example, in subsequent positioning of mobile stations for which locations are not already known, such as mobile stations not equipped with GPS technology. The estimated base station position may also be used to update a database of base station coordinates for the wireless network.</p>
