The present invention is a novel and improved method and apparatus for performing position location in wireless communications system. One embodiment of the invention comprises a method for performing position location including the steps of receiving a set of higher resolution sample data at a resolution interval, accumulating said higher resolution sample data over a chip interval yielding accumulation sums, and correlating said accumulation sums with a correlation code at a set of offsets which are separated by said resolution interval.

La présente invention concerne un procédé et un appareil nouveau et amélioré d'exécution d'une localisation de position dans un système de communication sans fil. Un mode de réalisation de l'invention comprend un procédé d'exécution d'une localisation de position comprenant les étapes consistant à recevoir un ensemble de données d'échantillon de résolution plus élevé à un intervalle de résolution donné, à accumuler lesdites données d'échantillon de résolution plus élevées sur un intervalle de plus produisant des sommes d'accumulation, et à corréler lesdites sommes d'accumulation avec un code de corrélation sur un ensemble de décalages lesquels sont séparés par ledit intervalle de résolution.
