    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 cell update while in a Cell_FACH state are disclosed. After selecting a target cell, system information is read from the target cell including high speed downlink shared channel (HS-DSCH) common system information. A radio network temporary identity (RNTI) received in a source cell is cleared and a variable HS_DSCH_RECEPTION is set to TRUE. An HS-DSCH medium access control (MAC-hs) entity is configured based on the HS-DSCH common system information. High speed downlink packet access (HSDPA) transmission is then received in the target cell. A CELL UPDATE message is sent to notify of a cell change. The HSDPA transmission may be received using a common H-RNTI broadcast in the system information, a reserved H-RNTI as requested in a CELL UPDATE message, or a temporary identity which is a subset of a U-RNTI. The MAC-hs entity may be reset.

    摘要: A method and apparatus for performing state transition of a wireless transmit/receive unit (WTRU) which supports enhanced dedicated channel (E-DCH) in the CELL_FACH state is disclosed. Uplink data is transmitted via an E-DCH while operating in a CELL_FACH state. A radio resource control (RRC) signal, which includes a reconfiguration message, is received while the WTRU is assigned an E-DCH resource. A reconfiguration of the physical channels is performed according to the RRC reconfiguration message. A transition to a CELL_DCH state is performed and uplink data is transmitted in the CELL_DCH state via the E-DCH. In-synch and out-of-synch parameters are reported.

    摘要: A method and apparatus for radio link synchronization and power control in CELL_FACH state and idle mode are disclosed. A wireless transmit/receive unit (WTRU) transmits a random access channel (RACH) preamble and receives an acquisition indicator acknowledging the RACH preamble via an acquisition indicator channel (AICH) and an index to an enhanced dedicated channel (E-DCH) resource. The WTRU determines a start of an E-DCH frame. An F-DPCH timing offset is defined with respect to one of the RACH access slot and an AICH access slot carrying the acquisition indicator. A relative F-DPCH timing offset may be signaled to the WTRU and the WTRU may determine a start of an E-DCH frame based on the relative F-DPCH timing offset and timing of an AICH access slot including the acquisition indicator. The WTRU may transmit a dedicated physical control channel (DPCCH) power control preamble before starting an E-DCH transmission.
