Title (EN) SYNCHRONISATION IN CELLULAR NETWORKS
(FR) SYNCHRONISATION DANS DES RÉSEAUX CELLULAIRES
Abstract: front page image
(EN) Methods and systems for initial access of a mobile device to a cellular radio network, in particular for the communication of timing information from a base station to a mobile device. The methods and systems are particularly appropriate for system using beam forming in which synchronisation data may be transmitted in variable positions in transmitted radio frames. Synchronisation sequences are modified, for example by a cyclic shift, according to the time of their transmission.
(FR) L'invention concerne des procédés et des systèmes d'accès initial d'un dispositif mobile à un réseau radio cellulaire, en particulier pour la communication d'informations de synchronisation d'une station de base à un dispositif mobile. Les procédés et les systèmes sont particulièrement appropriés pour un système utilisant une formation de faisceau dans laquelle des données de synchronisation peuvent être transmises dans des positions variables dans des trames radio transmises. Les séquences de synchronisation sont modifiées, par exemple par un décalage cyclique, en fonction du temps de leur transmission.
