Abstract
A wireless broadband communications system and method that achieves reduced latency for high priority data when multiplexed with lower priority data for transmission over a TDD point-to-point radio link. The system prepares multiple data streams for transmission over a TDD radio link by buffering multiple data streams containing high and low priority packets in separate queues based upon their corresponding priority level. Each packet in the higher priority queues has a specified size, and a header defining the type of service provided and the packet destination. Next, the packets in the lower priority queues are fragmented to a reduced size based upon the data capacity of the link. The high priority packets and the fragmented, low priority packets are arranged in a sequence such that the high priority packets are transmitted first, and the low priority packets are transmitted when no data is buffered in any high priority queue.
