Patent ID: 7248567

Claim:
A method for integrating time division duplex (TDD) and frequency division duplex (FDD) in wireless communication systems, the method comprising the steps of: receiving radio access bearer (RAB) requests at a radio network controller (RNC) along with a plurality of parameters regarding the request; estimating at the RNC a degree of symmetry in uplink (UL) and downlink (DL) connections required to support communication associated with the RAB requests; selecting either a TDD connection for both UL and DL or a FDD connection for both the UL and DL based on the estimated symmetry of the UL and DL connections, wherein a difference is calculated between a data rate on the uplink and a data rate on the downlink and TDD is selected where said difference is greater than a predetermined threshold and FDD is selected where the difference is not greater than the predetermined threshold.
