Abstract

L'invention concerne des systèmes et des procédés de support multi-source et multi-horloge dans des systèmes multi-opérateurs. Dans certains modes de réalisation, un système comprend une unité maître couplée à de multiples sources de station de base, le fonctionnement d'au moins deux des multiples sources de station de base étant référencé à différents maîtres de synchronisation. En outre, le système comprend des points d'accès couplés à l'unité maître. L'unité maître identifie une synchronisation subordonnée sur la base d'une combinaison d'informations de synchronisation reçues en provenance des multiples sources de station de base. L'unité maître communique avec les multiples sources de station de base pour identifier une pluralité de temps delta, un temps delta dans la pluralité de temps delta décrivant un retard pour une source de station de base par rapport à la synchronisation subordonnée. En outre, l'unité maître fournit des transmissions des multiples sources de station de base aux points d'accès pour une transmission à partir des points d'accès au niveau de limites d'antenne pour les points d'accès.
