Abstract
Transmission of broadcast streams in multiple sectors is synchronized based on time stamps or sequence numbers in data packets received at the base station. The base stations use the time stamps to calculate a frame transmission start time and start position for the data packets. The base station monitors the packet latency of data within its buffer based on the time stamp in the data packets and initiates a resynchronization procedure if the packet latency exceeds predetermined bounds.
