摘要： Techniques for component carrier-specific reconfiguration are disclosed. A wireless transmit/receive unit (WTRU) is capable of transmitting or receiving via multiple component carriers. The WTRU may perform component carrier reconfiguration on a component carrier basis to add, remove or replace a component carrier. Discontinuous reception (DRX) and/or discontinuous transmission (DTX) may be performed on at least one component carrier, wherein DRX and/or DTX patterns on the component carriers may not overlap each other. A random access procedure may be performed at the target cell on one component carrier while other component carriers are inactive. The component carrier-specific reconfiguration or handover of a component carrier or a channel may be implemented in coordinated multiple point transmission (CoMP), wherein a handover of a control channel, not a traffic channel, may be performed. Alternatively, a handover of a traffic channel may be performed.

摘要： A method and apparatus for processing advanced long term evolution (LTE-A) system information (SI) are described. When a wireless transmit/receive unit (WTRU) is in an idle mode/state, an LTE-A SI broadcast may be received on at least one downlink (DL) anchor carrier, including a physical DL shared channel (PDSCH) having paging message content. At least one SI-change parameter included in the paging message content may be decoded and processed. The SI-change parameter may include a flag used to indicate an SI change on a logical partition, (a primary or a secondary SI broadcast group information change). When the WTRU is in a connected mode/state, an LTE-A SI-CHANGE-radio network temporary identifier (RNTI) transmission may be received during a modification period (MP), and an SI change may be performed during a subsequent MP. At least one SI-change parameter included in the SI-CHANGE-RNTI transmission may be decoded and processed.

摘要： A method and apparatus are described for operating a wireless transmit/receive unit (WTRU) in a discontinuous reception (DRX) mode employing carrier aggregation. In one scenario, a physical downlink (DL) shared channel (PDSCH) is received on a DL component carrier (CC) of a particular serving cell during a cell-specific active time, whereby the DL CC is associated with an uplink (UL) CC. Then, a physical DL control channel (PDCCH) is monitored for DL assignments for the particular serving cell, and UL grants for the UL CC, during the cell-specific active time. In another scenario, a first subset of CCs is configured for PDCCH reception, and a second subset of the CCs is not configured for PDCCH reception. DRX is applied to at least one CC in the second subset based on a PDCCH active time of at least one of the CCs in the first subset.
