1. A method for 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) predicting uplink and downlink bandwidth requirements in accordance with associated and respective type of service session bandwidth parameters to establishing an uplink/downlink bandwidth requirement ratio; (b) allocating uplink and downlink time slots in a frame with the established uplink/downlink bandwidth ratio; and (c) enabling uplink transmissions during the allocated uplink time slots and downlink transmissions during the allocated downlink time slots.
