Abstract

Спосіб і пристрій для виконання пошуку пілот-сигналу у мережі безпровідного зв'язку визначають місцеположення мобільної станції у мережі, яке потім використовується для визначення розмірів вікна пошуку та інших параметрів пошуку, що використовуються для пошуку всіх пілот-сигналів, ідентифікованих у групі пілот-сигналів. Розмір вікна пошуку визначається також на основі місцеположення мобільної станції та на основі інших компонентів, пов'язаних з багатошляховим проходженням переданого пілот-сигналу.
