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-HSDP A) 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 deactivation of the supplementary carrier.

A method is disclosed comprising a wireless transmit/receive unit, WTRU, receiving an indication from a Node B that a cell is restricted, wherein the indication is capable of being interpreted by the WTRU and other WTRUs. The WTRU receives a closed subscriber group, CSG, broadcast that indicates that the cell is reserved for a CSG, wherein the CSG broadcast is configured to be interpreted by the WTRU, and wherein the CSG broadcast is configured to be unable to be interpreted by the other WTRUs. The WTRU further interprets the CSG broadcast; and the WTRU ignores the indication that the cell is restricted and trying to connect to the Node B based on the interpretation of the CSG broadcast that indicates that the cell is reserved for the CSG.

A method and an apparatus for serving high speed downlink shared channel (HS-DSCH) cell change are disclosed. A wireless transmit/receive unit (WTRU) receives pre-configured serving cell information for a target cell. The WTRU reports a measurement report and starts monitoring a high speed shared control channel (HS-SCCH) on the target cell. The WTRU may receive an HS-SCCH order over the target cell and/or a radio resource control (RRC) reconfiguration message over a source cell indicating a serving HS-DSCH cell change to the target cell. The WTRU may act upon all information elements of the RRC reconfiguration message in case that the RRC reconfiguration message is received prior to the HS-SCCH order, and act upon the pre-configured serving cell information in case that the HS-SCCH order is received prior to the RRC reconfiguration message.

A method and an apparatus for providing control information for multi-carrier uplink transmission are disclosed. A wireless transmit/receive unit (WTRU) may set a happy bit for enhanced dedicated channel (E-DCH) transmissions on each uplink carrier considering aggregated transmission capability over all uplink carriers. The happy bit is set to "unhappy" if the WTRU is transmitting as much scheduled data as allowed by a current serving grant, the WTRU has enough power available to transmit at a higher rate, and total E-DCH buffer status (TEBS) requires more than a pre-configured period to be transmitted with a current effective data rate aggregated over all uplink carriers. The WTRU may send scheduling information including power headroom measured on the anchor uplink carrier and/or power headroom measured on the supplementary uplink carrier. For power headroom measurements, the WTRU may initiate a short-lived dedicated physical control channel loop on the supplementary carrier.
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.

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.

A method for discontinuous reception (DRX) implemented in a wireless transmit/receive unit (WTRU) during cell reselection including initiating cell reselection; disabling DRX operation, wherein disabling DRX operation enables continuous reception; transmitting a CELL UPDATE message; receiving a CELL UPDATE CONFIRM message; and enabling DRX operation based on the received CELL UPDATE CONFIRM message.

摘要:
A method and an apparatus for wireless transmission using multiple uplink carriers are disclosed. A wireless transmit/receive unit (WTRU) using a primary and a secondary uplink carrier may transmit via the primary uplink carrier data, pilot and control channels for uplink transmissions on both uplink carriers, and transmit a data channel and a pilot channel via the secondary uplink carrier. Alternatively, the WTRU may transmit via the primary uplink carrier data, pilot, and control channels for uplink transmission on the primary uplink carrier, and transmit via the 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.
