APPARATUS AND METHOD FOR DISTRIBUTING FRAME SYNCHRONIZATION INFORMATION AT A BASE STATION

摘要

A method and system distributes frame synchronization information at a base station implementing air interfaces of at least two different standards and to a base station implementing air interfaces of at least two different standards. Frame synchronization information is generated in a clock unit for at least two air interface standards. Synchronization bursts containing the frame synchronization information are transferred from the clock unit to processing units over a serial bus using time-division multiplexing for synchronization bursts addressed to the processing units of different air interface standards. The frame synchronization information is extracted in each processing unit from the received synchronization burst of its respective air interface standard.
