METHOD, DEVICE AND SYSTEM FOR SYNCHRONIZATION IN WIRELESS NETWORKS PROVIDING MULTICAST/BROADCAST

摘要

Method, device and systems are provided for synchronizing data transmission of multicasting/broadcasting services (MBS) by base stations. Synchronization information enables all base stations to start transmitting MBS data at a synchronized starting time point. Meanwhile, each base station receives the MBS data to be transmitted and determines whether any of the MBS data has not been properly received. If so, the respective base station initiates a process to recover the missing MBS data or to obtain within a pre-determined time interval, information regarding the missing data to determine duration of the time period that would have been required for transmitting the missing MBS. If the missing data has not been timely recovered, the respective base station determines a starting point and the duration of a silence period based on information obtained, and refrains from transmissions along the channel allocated for transmission of MBS data, during that silence period.
