Method and system for integrating resource allocation between time division duplex and frequency division duplex in wireless communication systems

A system for integrating TDD and FDD in a communication system, the system comprising:

• a core network (CN);
• a time division duplex radio network controller (TDD RNC);
• a frequency division duplex radio network controller (FDD RNC);
• and,
• a TDD-FDD selector configured to receive a RAB request and to estimate a symmetry of data rates between uplink (UL) and downlink (DL) connections that is required to support the RAB assignment request and to calculate a difference between a data rate on the uplink and a data rate on the downlink, and to make a decision to assign radio resources in either TDD mode for both UL and DL or FDD mode for both UL and DL based on the estimated symmetry of data rates between UL and DL connections, wherein TDD is selected where the difference of data rates between UL and DL connections is greater than a threshold and FDD is selected where the difference of data rates between UL and DL connections is not greater than the threshold.
