摘要： A method and wireless transmit receive unit (WTRU) are disclosed that is configured to perform cell reselection to another cell when the WTRU is in a CELL_FACH state using an Enhanced-Dedicated Channel (E-DCH). The cell reselection is based on internal measurements by the WTRU. Alternatively, the cell reselection can be WTRU based on the WTRU measurements reported to the network.

摘要： Methods and apparatus utilize hybrid automatic repeat request (HARQ) transmissions and retransmissions that are usable on multiple carriers, i.e. joint HARQ processes. For example, a downlink (DL) shared channel transmission of a joint HARQ process is received on one of the carriers. A first part of an identity of the joint HARQ process is determined by using HARQ process identity data received on a shared control channel. A second part of the joint HARQ process identity is determined using additional information. The joint HARQ process identity is then determined by combining the first part and the second part. A WTRU is provided that is configured to receive the DL shared channel and to make the aforementioned determinations. A variety of other methods and apparatus configurations are disclosed for utilizing joint HARQ processes, in particular in the context of DC-HSDPA.

摘要： A wireless transmit/receive unit (WTRU) may send a bundled transmission of a packet repeatedly over at least two consecutive transmission time intervals (TTIs). The WTRU may not process a hybrid automatic repeat request (HARQ) feedback for the packet after sending the bundled transmission. The bundled transmission may be configured per HARQ process. The WTRU may override the bundled transmission and may transmit a HARQ retransmission of another packet in one of the TTIs scheduled for the bundled transmission if a TTI scheduled for the HARQ retransmission of another packet overlaps the TTIs scheduled for the bundled transmission. Alternatively, the WTRU may transmit a non-bundled transmission of a packet and send a bundled HARQ transmission of the packet on a condition that HARQ feedback indicates a failure of delivery of the packet. The WTRU may not process an HARQ feedback in an E-HICH for the packet after sending the bundled transmission.

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： Methods for implementing transmission time interval (TTI) bundling, and a wireless transit/receive unit (WTRU) and a base station configured to process the methods are shown. The method includes the WTRU receiving a TTI control signal and/or configuration message from a network and the WTRU transmitting TTI control signals to the network.

摘要： A method and apparatus for selecting an enhanced dedicated channel (E-DCH) transport format combination (E-TFC) 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 index to an E-DCH resource in response to the RACH preamble. The WTRU may estimate a power headroom based on the maximum WTRU transmit power, power offset value, and the last successfully transmitted RACH preamble transmit power. The WTRU restricts an E-TFC based on the estimated power headroom, and selects an E-TFC based on a set of supported E-TFCs. The WTRU then generates, and transmits, a protocol data unit (PDU) based on the selected E-TFC.

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 to provide antenna transmit diversity. A wireless transmit/receiver unit (WTRU) may comprise multiple antennas. A channel condition for each of the antennas may be determined. A probing phase may be used in order to determine the channel conditions. During a period of the probing phase, a probing signal from each antenna may be transmitted during a respective time interval. The WTRU transmit power may or may not be held constant. A Node B may receive each probing signal and determine channel quality information. The Node B may adjust the determined channel quality information if there is a power offset between the signals. The Node B may send the channel quality information to the WTRU. The WTRU may switch an antenna to use for uplink transmission based on the received channel quality information.
