Patent

CA 2695976

A base station apparatus is disclosed for use in a mobile communication system including multiple cells having multiple sectors. The base station apparatus includes a synchronization channel generation unit configured to generate a synchronization channel for use in cell search by a user apparatus and a transmitting unit configured to wirelessly transmit a signal including the synchronization channel. The synchronization channel includes a primary synchronization channel and a secondary synchronization channel. The primary synchronization channel includes multiple types of sequences, and the secondary synchronization channel transmitted in a sector of a cell includes a code derived from a predefined generation polynomial equation corresponding to the primary synchronization channel.

L'invention concerne l'utilisation possible d'un dispositif de station de base utilisé dans un système de communication mobile comprenant une pluralité de cellules ayant une pluralité de secteurs. Le dispositif de station de base comprend : des moyens pour générer un canal de synchronisation utilisé pour une recherche de cellule par un dispositif utilisateur ; et des moyens pour une transmission par hyperfréquences d'un signal contenant le canal de synchronisation. Le canal de synchronisation a un canal de synchronisation primaire et un canal de synchronisation secondaire. Le canal de synchronisation primaire a une pluralité de types de séquences. Le second canal de synchronisation qui est transmis dans un certain secteur d'une certaine cellule contient un code dérivé d'un code polynomial de génération prédéterminé correspondant au canal de synchronisation primaire.
