Abstract:
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) determining an uplink bandwidth requirement and a downlink bandwidth requirement of the communication link, wherein the uplink and downlink bandwidth requirements are determined using associated and respective uplink and downlink bandwidth utilization parameters reflective of a statistical average bandwidth utilization in the communication link, and wherein the bandwidth utilization parameters are calculated by monitoring bandwidth utilization in the communication link over a pre-determined period of time;(b) calculating an uplink/downlink bandwidth requirement ratio based upon the uplink and downlink bandwidth requirements of the link;(c) allocating uplink and downlink time slots in response to the calculated uplink/downlink bandwidth ratio; and(d) periodically enabling uplink transmissions during the allocated uplink time slots and downlink transmissions during the allocated downlink time slots.
