    摘要： A method and an apparatus for simultaneously receiving on two carriers and performing discontinuous transmission (DTX) and discontinuous reception (DRX) in dual cell high speed downlink packet access (DC-HSDPA) are disclosed. A wireless transmit/receive unit (WTRU) receives a message for activating DRX for at least one of an anchor carrier and a supplementary carrier and applies the same DRX pattern to the anchor carrier and the supplementary carrier upon reception of the message. The message may be received via a high speed shared control channel (HS-SCCH) order. The WTRU may activate or de-activate the supplementary carrier based on the physical layer signal. Upon activation of the supplementary carrier, the WTRU may apply the same DRX pattern on both the anchor carrier and the supplementary carrier. The WTRU may flush a hybrid automatic repeat request (HARQ) buffer associated with the supplementary carrier upon de-activation of the supplementary carrier.

    摘要： Systems and method for uplink feedback for multipoint transmission of high-speed downlink packet access (MP-HSDPA) that may improve downlink transmission efficiency and cell coverage. For example, Channel Quality Indicator (CQI) and/or Precoding Control Indicator (PCI) that may be calculated to accommodate the needs of coordinated dynamic network scheduling. Additionally, various frame structures may be generated for the uplink feedback that may carry multiple CQI and HARQ-ACK feedbacks from MP-HSDPA. The frame structures may also address asynchronous downlink transmissions between two cells. Moreover, HS-DPCCH power offset settings for both CQI and HARQ-ACK fields that may be modified and/or created to ensure reliable uplink feedback transmission.

    摘要： Systems and methods for managing control signaling overhead for a multi-carrier HSDPA (MC-HSDPA) may be disclosed. In particular, a plurality of downlink carriers may be received and bundled or paired. Configuration information indicative of the bundling may then be generated and transmitted. Additionally, one or more components such as antennas, user equipment (UE), and the like may receive an indication of a configuration or state via a high speed shared control channel (HS-SCCH) order where the indication includes order bits and order types and the configuration may be applied to activate and/or deactivate the components or operations such as uplink closed-loop transmit diversity (CLTD), uplink multiple-input multiple-output (MIMO). The order bits and/or order types may also be extended to support the activation/deactivation of additional carriers of MC-HSDPA.

    摘要： Systems, methods, and instrumentalities are disclosed herein to determine a gain factor. A user equipment (UE) may determine that an S-E-DPCCH and an E-DPCCH are to be transmitted on a primary stream. The UE may calculate an E-DPCCH gain factor using a gain factor calculation and apply the -DPCCH gain factor. The UE may calculate an E-DPCCH gain factor reduction. For example, the E-DPCCH gain factor reduction may compensate for changes from single stream transmission to multiple stream transmission. The UE may apply the E-DPCCH gain factor reduction to the E-DPCCH gain factor. The UE may apply the E-DPCCH gain factor reduction to an S-E-DPCCH gain factor.

    摘要： A wireless transmit/receive unit (WTRU) may transmit via a primary uplink carrier data, pilot and control channels for uplink transmissions on multiple uplink carriers, and transmit a data channel and a pilot channel via a secondary uplink carrier. Alternatively, the WTRU may transmit via a primary uplink carrier data, pilot, and control channels for uplink transmission on the primary uplink carrier, and transmit via a secondary uplink carrier data, pilot, and control channels for uplink transmissions on the secondary uplink carrier. Each uplink carrier may be associated with at least one specific downlink carrier such that the WTRU applies control information received on a downlink carrier to uplink transmissions on an uplink carrier associated with the downlink carrier on which the WTRU receives the control information.

    摘要： Method and apparatus for uplink transmission using multiple antennas are disclosed. A wireless transmit/receive unit (WTRU) performs space time transmit diversity (STTD) encoding on an input stream of a physical channel configured for STTD. Each physical channel may be mapped to either an in-phase (I) branch or a quadrature-phase (Q) branch. The WTRU may perform the STTD encoding either in a binary domain or in a complex domain. Additionally, the WTRU may perform pre-coding on at least one physical channel including the E-DPDCH with the pre-coding weights, and transmitting the pre-coded output streams via a plurality of antennas. The pre-coding may be performed either after or before spreading operation.
