Abstract:
1. A method for synchronizing corresponding streams of packets sent to a mobile station from two different base stations, each of the packets having a corresponding Sequence number, the method comprising generating a stream of link layer frames by each of the base stations wherein each of the frames is of the same length, in each of the base stations filling in the frames with the packets starting with the same one of the packets, transmitting fully filled-in frames from each of the base stations to the mobile station, detecting two stream of frames at the mobile station wherein one of the streams is transmitted by the first of the base stations and another of the streams is transmitted by the second of the base stations, determining the packet sequence number of reach of the packets in each of the streams, and initiating a resynchronization procedure whenever packets in one or both of the steams do not have packet sequence numbers that are consecutive.
