    摘要: A method and apparatus are disclosed for selecting a channel for uplink communication includes determining whether a cell supports transmission over an enhanced random access channel (E-RACH) and selecting whether to send uplink communications over the E-RACH or a random access channel. A method for selecting a transmission time interval (TTI) for use on an E-RACH includes evaluating radio conditions measured at a user equipment and selecting a long TTI if radio conditions are bad and selecting a short TTI if radio conditions are good. Alternatively, the TTI can be selected based on an amount of data to be transmitted on the uplink. A user equipment, an integrated circuit, or a Node B can be configured to perform either method.

    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 supporting home Node B (HNB) services are disclosed. A wireless transmit/receive unit (WTRU) receives HNB access restriction information from an HNB and accesses the HNB if an access to the HNB is allowed based on the HNB access restriction information. The HNB access restriction information may be a closed subscriber group identity (CSG ID), a status bit indicating whether an HNB cell is available or not, an identity of WTRUs that are allowed to access the HNB, information indicating whether an access to a cell is barred or not. The WTRU may trigger measurements for cell reselection even though signal strength on a currently connected cell is above a threshold. The measurement may be triggered manually, periodically, under the instruction from the network, or based on a neighbor cell list including information about HNB cells located nearby.

    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.
