METHOD AND DEVICE FOR SYNCHRONIZATION IN WIRELESS NETWORKS

摘要

A method and device are provided for synchronizing data transmission of multicasting/broadcasting services (MBS) by a plurality of Base Stations. 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 may initiate a process to recover the missing MBS data and/or to obtain 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 the 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.

主权项

1. A base station operable to synchronize transmission of multicast-broadcast service (MBS) data with a first group of base stations of an MBS zone in a wireless network, comprising:
a transceiver operable to
receive synchronization information, the synchronization information including at least scheduling information for the MBS zone,receive MBS data packets related to an MBS content, andtransmit the MBS data packets in accordance with the synchronization information; and a processor operable to
process the MBS data packets during a distribution period;detect faulty MBS data packets; and on condition that no faulty MBS data packets are detected, map the MBS data packets synchronously to an MBS region of a radio frame, according to the scheduling information, and on condition that a faulty MBS data packet is detected, cease mapping the MBS data packets to the radio frame for a silence period corresponding to a length of the faulty MBS data packet.
