    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 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 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.
