<p>The present invention relates to a direct amplifying station and positioning method for mobile station . The direct amplifying station according to the present invention is adding following items to the downlink electrical circuits of present direct amplifying station: synchronous search unit for searching the synchronized signal of the base station, delay unit for producing fixed time delay of frame start time of cell identifier signal and fixed time delay of frame start time of base station pilot signal, and cell identifier generation mode for generating cell identifier symbol. The method for mobile station positioning is as follow: determining the mobile stations in the coverage area of the direct amplifying station based on the coherence of fixed time delay and time difference between base station pilot signal and cell identifier, then determining the distance from the mobile station to the direct amplifying station using TOA function, thus improving the precision of positioning of mobile stations in the coverage area of the direct amplifying station. Said direct amplifying station which supports mobile station positioning is easy to be realized, and can meet the requirement of positioning of plurality of mobile stations in the coverage area of the direct amplifying station at the same time.</p> |
