    摘要： A method and apparatus are directed toward optimizing clear channel assessment (CCA) parameters in a wireless local area network having an access point (AP) and at least one station. An upper bound and a lower bound for an energy detect threshold (EDT) parameter are determined. A value of the EDT parameter is calculated and is bound by the upper bound and the lower bound. The EDT parameter is updated. The method can be performed at each station or at the AP, with the updated CCA parameters being signaled to each station associated with the AP.

    摘要： A method and apparatus for performing a serving high speed downlink shared channel (HS-DSCH) cell change from a source cell to a target cell are disclosed. A radio network controller (RNC) may pre-load a wireless transmit/receive unit (WTRU) with HS-DSCH configuration for the target cell. The WTRU receives and stores the pre-loaded HS-DSCH configuration. The WTRU may start monitoring a high speed shared control channel (HS-SCCH) on the target cell using the pre-loaded HS-DSCH configuration for the target cell on a condition that a measurement report is triggered by the event 1D. The WTRU may initiate a timer when the WTRU starts monitoring the HS-SCCH on the target cell and stop monitoring the HS-SCCH on the target cell upon expiry of the timer.

    摘要： A method and apparatus for performing an enhanced random access procedure in a Cell_FACH state are disclosed. A wireless transmit/receive unit (WTRU) transmits a random access channel (RACH) preamble for random access. If a positive acknowledgement (ACK) is received in response to the RACH preamble, the WTRU enters a contention resolution phase and transmits a message via an enhanced dedicated channel (E-DCH). If contention resolution fails, the RACH preamble is retransmitted. A contention back-off timer may be used for retransmission. A physical random access channel (PRACH) code may be reselected. The RACH preamble may be retransmitted using a reserved PRACH resource so that E-DCH resource is allocated to the collided WTRUs. Data transmitted during the contention resolution phase may remain in a hybrid automatic repeat request (HARQ) buffer. The MAC-i/is entity may be reset. All data sent during the contention resolution phase may be stored in a temporary buffer.

    摘要： A method and apparatus for managing a collision in random access channel (RACH) access transmissions are disclosed. A wireless transmit/receive unit (WTRU) transmits WTRU-dependent information to confirm that a detected acquisition indicator (AI) is intended to the WTRU. The WTRU-dependent information may be transmitted separately after detecting the AI, may be transmitted along with a RACH preamble, or may be sent in an E-RACH message. The WTRU-dependent information may be a random number, a sequence or scrambling code randomly selected from a pre-determined set of sequences or scrambling codes. Alternatively, the WTRU-dependent information may be a pre-configured identifier, or information derived from the pre-configured identifier. Alternatively, after detecting an AI, the WTRU may randomly select an enhanced dedicated channel (E-DCH) resource from a set of E-DCH resources associated with an RACH resource used for transmission of the RACH preamble and transmit an E-RACH message using the selected E-DCH resource.

    摘要： A method and apparatus for reconfiguring a wireless transmit/receive unit (WTRU) are directed to receiving an active set update message indicating that a mode of operation allowing a certain modulation scheme is enabled or disabled and performing at least one of: performing a MAC reset procedure, updating a set of reference enhanced transport format combination indicators (E-TFCIs) and associated power offsets, determining actions related to E-DPCCH boosting, modifying information related to an enhanced dedicated channel (E-DCH), and modifying an index that indicates an E-DCH transport block size table. The update message includes at least one modified information element (IE).
