Abstract: A wireless transmit/receive unit (WTRU) includes circuitry configured to receive information from a base station indicating an assignment of periodic time slots to transmit sounding signals and circuitry configured to transmit sounding signals to the base station in the assigned periodic time slots in response to the received information, wherein a timing of transmission of the sounding signals in response to the received information differs between a time division duplex mode and a frequency division duplex mode, and wherein the transmitted sounding signals are distinguishable from sounding signals from other WTRUs.

Abstract: A method and apparatus for controlling an optimization of handover procedures between universal terrestrial radio access (UTRA) release 6 (R6) cells and UTRA release 7 (R7) cells are disclosed. When a wireless transmit/receive unit (WTRU) is moving between an R6 cell and an R7 cell, or between R7 cells, a handover is initiated from a source Node-B to a target Node-B. In the R7 cell, the enhanced medium access control (MAC) functionality including flexible radio link control (RLC) protocol data unit (PDU) size and high speed MAC (MAC-hs) segmentation and multiplexing of different priority queues are supported. After the handover, a MAC layer and/or an RLC layer are reconfigured or reset based on functionality supported by the target Node-B.

Abstract: A wireless transmit/receive unit includes at least one processor that receives a high speed physical downlink shared channel, and in response, transmits at least one random access channel preamble followed by ACK/NACK and channel quality indicator (CQI) information. The at least one random access channel preamble is selected from a set of random access preambles reserved for the ACK/NACK and CQI information.

Abstract: A variety of wireless communication methods and apparatus for supporting reconfiguration of radio link control (RLC) parameters are disclosed. 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. Flexible size RLC PDUs may be discarded and a message indicating the discarded flexible size RLC PDUs may be transmitted. The flexible size RLC PDUs may be modified such that they correspond to a set of pre-defined sizes.
