Abstract: Method and apparatus for reporting feedback information are disclosed. A wireless transmit/receive unit (WTRU) may receive configuration information indicating a plurality of downlink carriers and indicating a plurality of physical control channel resources for feedback. Further, the WTRU may receive a control signal indicating a downlink transmission for reception on one of the plurality of downlink carriers. The WTRU may receive the downlink transmission on the one of the plurality of downlink carriers. The WTRU may transmit feedback for the downlink transmission using one of the plurality of physical control channel resources. The one of the plurality of physical control channel resources may be selected from the plurality of physical control channel resources based on the control signal. In an example, the configuration information may indicate a first uplink carrier and a second uplink carrier for WTRU transmissions. The first uplink carrier may be a time division duplex (TDD) carrier.

Abstract: Method and apparatus for reporting feedback information are disclosed. A wireless transmit/receive unit (WTRU) may receive a first control message including both information indicating a first allocation of resources on a first downlink transmission for a first downlink carrier and a first indication of resources for feedback corresponding to the first downlink transmission. Further, the first indication of resources for feedback may include at least one orthogonal frequency division multiplex (OFDM) symbol and at least one subcarrier. Moreover, the WTRU may receive the first downlink transmission in the first allocation of resources on the first downlink carrier. Also, the WTRU may derive acknowledgement/negative acknowledgement (ACK/NACK) feedback corresponding to the first downlink transmission. Additionally, the WTRU may transmit the derived ACK/NACK feedback in the at least one OFDM symbol and on the at least one subcarrier, based on the first indication of resources for feedback.

Abstract: Method and apparatus for reporting feedback information are disclosed. A wireless transmit/receive unit (WTRU) may receive an allocation message which indicates an allocation of downlink resources for a downlink transmission and an allocation of a first uplink control channel. Further, the indicated allocation of the first uplink control channel may indicate a starting symbol for the first uplink control channel and subcarriers for the first uplink control channel. Also, the WTRU may receive the downlink transmission on a downlink carrier in the indicated allocation of downlink resources for the downlink transmission. Moreover, the WTRU may transmit a plurality of uplink control channels carrying hybrid automatic repeat request (HARQ) acknowledgment/negative-acknowledgement (ACK/NACK) information for the downlink transmission and other control information. In addition, the plurality of uplink control channels may include the first uplink control channel.

Abstract: Method and apparatus for reporting feedback information for multi-carrier operation are disclosed. A wireless transmit/receive unit (WTRU) is configured with multiple carriers. A base station may allocate an uplink (UL) control channel associated with a single UL carrier, for the WTRU. The base station may transmit, to the WTRU, a plurality of data signals via at least two downlink (DL) carriers using orthogonal frequency division multiple access (OFDMA) and multiple input multiple output (MIMO), and may receive from the WTRU hybrid automatic repeat request (HARQ) acknowledgment/negative-acknowledgement (ACK/NACK) information, for the plurality of data signals transmitted via the at least two DL carriers, on the UL control channel. The HARQ ACK/NACK information may include at least two HARQ ACK/NACKs ANDed together. In addition, the base station may transmit, to the WTRU, information including a set of the DL carriers, each having an associated three bit indicator, for DL data transmission.
