    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: Methods and systems for enabling MU-MIMO functions on a UE are disclosed. A precoder codebook with precoding matrices can be generated to assist in improving system throughput. Existing specifications designed for two bit precoding information can be used to communicate higher numbers of bits of precoding information by reinterpreting fields described by such specifications. Channel state information can be provided to a base station using several disclosed feedback mechanisms. A UE can determine a current MIMO transmission mode using various implicit and explicit dynamic signaling mechanisms or semi-dynamic signaling where MIMO mode data is received from a higher layer.

    摘要: Uplink precoding in closed loop transmit diversity (CLTD). The methods and apparatus relate to precoder operations during an initial stage using default precoder tap weights, and a second stage wherein precoder weights obtained from a precoder control indicator channel information are used, provided the signal quality of the precoder control indicator channel is sufficiently reliable. The methods and apparatus also relate to procedures for responding to detection of an unreliable pre-coding control information (PCI) carried in a downlink feedback signal.

    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.

    摘要: Feedback information for multiple serving cells are transmitted on high speed dedicated physical control channel (HS-DPCCH). A slot format for transmitting feedback information is determined based on the number of configured secondary serving cells and whether multiple input multiple-output (MIMO) is configured in the serving cells. Spreading factor is reduced to 128 when two secondary serving cells are configured and MIMO is configured in at least one of the two configured secondary serving cells, or when three secondary serving cells are configured. The serving cells are grouped into feedback groups, each feedback group having one or more serving cells. Channel coding may be applied to feedback information for the feedback groups. The resulting encoded feedback information for the feedback groups is concatenated to form composite feedback information.

    摘要: A method and apparatus are described for allocating resources for an enhanced physical hybrid automatic repeat request (HARQ) channel (E-PHICH). A subset of an enhanced physical downlink control channel (E-PDCCH) may be allocated for use by the E-PHICH. The E-PDCCH may be defined by at least one of enhanced resource element groups (eREGs) and enhanced control channel elements (eCCEs). Each eCCE may be formed by grouping a plurality of eREGs. Each eREG may contain at least one resource element (RE). Alternatively, a subset of eREGs may be allocated as E-PHICH resources. E-PDCCH physical resource block (PRB) pairs may be selected as a resource for the E-PHICH. An indication of the number of the eCCEs may be broadcast to a wireless transmit/receive unit (WTRU).

    摘要: A method and apparatus are used for detecting a radio link (RL) failure and a post verification process. A quality of a downlink fractional dedicated physical channel (F-DPCH) is monitored once a transmission on an enhanced dedicated channel (E-DCH) has begun. It is determined whether the quality of the downlink F-DPCH is below a predefined threshold. If the quality is below the predefined threshold, then an occurrence of an RL failure is declared and a transmission over the E-DCH in a cell forward access channel (CELL_FACH) state is terminated. In a case of the post verification failure, E-DCH resources are released.

    摘要: A method and an apparatus for utilizing multiple carriers are disclosed. A wireless transmit/receive unit (WTRU) capable of receiving on a single downlink carrier at a time may tune the receiver to one downlink carrier and switch the downlink carrier in accordance with a configured pattern. The WTRU may switch the carrier from an anchor carrier to a non-anchor carrier at a high speed shared control channel (HS-SCCH) sub-frame boundary, and switches back at an end of a subsequent high speed physical downlink shared channel (HS-PDSCH) subframe. The WTRU may switch the carrier at an HS-PDSCH sub-frame boundary. A WTRU capable of receiving on multiple downlink carriers simultaneously may tune the receiver to an anchor carrier and a supplementary carrier, and switch the supplementary carrier to another carrier based on a carrier switching order. The carrier switching order may be received via an HS-SCCH or via layer 2 signaling.
