Title (EN) METHOD FOR ACCOMODATING TIMING DRIFT BETWEEN BASE STATIONS IN A WIRELESS COMMUNICATIONS SYSTEM
(FR) PROCEDE POUR LA PRISE EN CHARGE D'UNE DERIVE TEMPORELLE ENTRE DES STATIONS DE BASE DANS UN SYSTEME DE COMMUNICATIONS SANS FIL
Abstract:
(EN) A method is provided for controlling communications between a base station and a mobile device. The method comprises enlarging a search window in which a transmission is expected to be received in response to the absence of an external timing signal, such as when the global positioning system (GPS) is shut down. Additionally or alternatively, the method further comprises altering the timing of a received signal relative to a search window, such as by delaying the timing of the received signal to move the signal toward the center of the search window.
(FR) La présente invention a trait à un procédé pour le contrôle de communications entre une station de base et un dispositif mobile. Le procédé comprend l'agrandissement d'une fenêtre de recherche dans laquelle la réception d'une transmission est prévue en réponse à l'absence d'un signal de synchronisation externe, tel que lors de la fermeture d'un système mondial de localisation. En outre ou en variante, le procédé comprend également la modification de la synchronisation d'un signal reçu par rapport à une fenêtre de recherche, par exemple par la temporisation de la synchronisation du signal reçu pour le déplacement du signal vers le centre de la fenêtre de recherche.
