Abstract

Die Erfindung beruht auf der Idee, die feste Zeitlage eines gemeinsamen Kanals aufzugeben und stattdessen den gemeinsamen Kanal zeitlich synchron zu den dedizierten Kanälen derjenigen Verbindung zu übertragen, der der gemeinsame Kanal momentan zugeordnet ist. Ein besonderer Vorteil dieser besonders in der Abwärtsrichtung von UMTS-Funk-Kommunikationssystemen einzusetzenden Lösung besteht darin, daß für die zeitgleich mit den Daten des dedizierten Kanals gesendeten Daten des gemeinsamen Kanals insbesondere Soft-Combining durchgeführt und damit dieselbe Übertragungsqualität wie bei der ausschließlichen Nutzung von dedizierten Kanälen garantiert werden kann.
