1. A method for operating a multi-mode wireless transmit/receive unit (WTRU) comprising:

  • receiving signals from both a time division duplex (TDD) and a frequency divisional duplex (FDD) system;

    establishing a connection with one of the systems;

    measuring a quality of signals received from both the TDD system and the FDD system;

    comparing the measured signal quality of the TDD system with a TDD threshold and the measured signal quality of the FDD system with a FDD threshold; and

    handing over from a current system in which a connection is established to an other system is the measured signal quality of the current system is below the threshold of the current system and the measured signal quality of the other system is above the threshold of the other system.
