| 20100110988 | METHOD AND APPARATUS FOR UTILIZING MULTIPLE CARRIERS IN HIGH SPEED PACKET ACCESS COMMUNICATIONS - 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. | 05-06-2010 |
| 20100111023 | METHOD AND AN APPARATUS FOR PROVIDING CONTROL INFORMATION FOR MULTI-CARRIER UPLINK TRANSMISSION - 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. | 05-06-2010 |

The initial DPCCH transmission power may be set based on a DPCCH transmission power on the primary uplink carrier or to a value signaled by a network. A default grant value may be used for initial E-DCH transmission upon activation of the secondary uplink carrier. | 05-27-2010 |

A first timer is initiated for an anchor carrier and a second timer is initiated for a supplementary carrier. A physical channel failure may be declared on a condition that either of the timers expire before a predefined number of in-synch indication received from a layer 1 (L1) entity is counted. Uplink transmission and enhanced dedicated channel (E-DCH) operations may be stopped on a supplementary carrier associated with the physical channel failure, but may be continued on an anchor carrier that has a physical channel established. If the physical channel failure is associated with the anchor carrier, uplink transmission and E-DCH transmission operations are stopped on all carriers. | 08-05-2010 |
