Abstract:
1. A method for adaptively duplexing transmissions in a communication link using a time division duplexing scheme wherein transmissions are communicated in an uplink direction during uplink time slots and wherein transmissions are communicated in a downlink direction during downlink time slots, comprising the steps of: (a) monitoring bandwidth usage in the communication link over a period of time to determine uplink and downlink bandwidth utilization parameters; (b) predicting an uplink bandwidth requirement and a downlink bandwidth requirement of the communication link, wherein the uplink and downlink bandwidth requirements are predicted using the uplink and downlink bandwidth utilization parameters; (c) setting an uplink/downlink bandwidth requirement ratio based upon the uplink and downlink bandwidth requirements of the link; (d) allocating uplink and downlink time slots in a frame with the set uplink/downlink ratio in response to bandwidth requests; and (e) enabling uplink transmissions during the allocated uplink time slots and downlink transmissions during the allocated downlink time slots.
