    Abstract: PROBLEM TO BE SOLVED: To disclose a variety of wireless communication methods and apparatus for supporting reconfiguration of radio link control (RLC) parameters.SOLUTION: A radio resource control (RRC) reconfiguration message is generated that indicates that an RLC unit in a wireless transmit/receive unit (WTRU) or a universal terrestrial radio access network (UTRAN) should be reconfigured from supporting flexible size RLC protocol data units (PDUs) to supporting fixed size RLC PDUs. If an information element (IE) "one sided RLC re-establishment" is present in the RRC reconfiguration message, only a receiving side subassembly in the RLC unit is re-established. Otherwise, both the receiving side subassembly and a transmitting side subassembly in the RLC unit are re-established.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and system for supporting next generation universal mobile telecommunication systems (UMTS) terrestrial radio access network (E-UTRAN).SOLUTION: A UTRAN sends to a multi-mode wireless transmit/receive unit (WTRU) a list of available radio access technologies in a coverage area of the UTRAN. The WTRU receives the list and may initiate a handoff on the basis of the list. The WTRU then sends its multi-mode/multi-RAT capability information including the E-UTRAN capability to the UTRAN. The UTRAN then sends a measurement capability message to the WTRU. The WTRU performs measurements on the basis of the measurement capability message and reports measurement results to the UTRAN. The UTRAN may initiate a handoff to an E-UTRAN on the basis of the measurement results.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and system for optimizing power resources in wireless devices.SOLUTION: There is provided a device which returns to a sleep mode so as to conserve energy when no data is being sent thereto. All device destination identifiers (14) are organized and transmitted at a time. If a message listing (10) search indicates that no message is being sent for a device, the device may continue with any other activity that needs servicing, or if no other activity is pending, it may shut down to conserve power until the next wake-up period arrives. If the search returns a positive indication, the count value (12) when the identifier is found can be used to determine the location of a pointer (16) to the message.
