Patent

CA 2513442

A method and system for performing initial cell search is disclosed. Step 1 (208) processing is preformed to detect a peak primary synchronization code (PSC) location (i.e. chip offset or chip location). Step 2 (210) processing is performed to obtain the toffset and code group. Step 3 (212) processing is performed to identify the midamble of a base station with which the WTRU performing the initial cell search may synchronize with.

Cette invention concerne un procédé et un système permettant d'effectuer une recherche de cellule initiale, lequel procédé comprend des étapes consistant : (1) à effectuer un traitement pour détecter l'emplacement d'un code de synchronisation primaire (PSC) de crête (par exemple décalage de bribe ou emplacement de bribe) ; (2) à effectuer un traitement pour obtenir le t¿décalage? et le groupe de codes ; et (3) à effectuer un traitement pour identifier la séquence intermédiaire d'une station de base avec laquelle l'unité de transmission et de réception sans fil (WTRU) effectuant la recherche de cellule initiale peut être synchronisée.
