Abstract
A method and device are provided for synchronizing data transmission of multicasting/broadcasting services (MBS) by a plurality of Base Stations. The method disclosed includes providing synchronization information to enable the plurality of Base Stations to start transmitting MBS data at a synchronized starting time point. Meanwhile, each of the Base Stations 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 the 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 duration of a silence period based on the information obtained, and refrains from transmitting signals along a communication channel allocated for transmission of MBS data, during that silence period.
