1. A dual mode wireless transmit/receive unit (WTRU) comprising:

  • a receiver configured to receive global system for mobile (GSM)/enhanced data rates for GSM evolution (EDGE) radio access network (GERAN) cell information while receiving wireless communications in a long term evolution (LTE)/evolved universal terrestrial radio access network (EUTRAN) cell;

    a processor configured to receive list of available cells and their technologies in order to perform measurements on LTE frequencies and GERAN frequencies to be used for a handover from a source LTE cell to other wireless coverage areas, including a target GERAN cell using the GERAN cell information; and

    a transmitter configured to send a measurement report of the measurements on the GERAN frequencies to a source evolved Node B (eNB).
