Claim Text:
1. A method for use in a wireless transmit/receive unit (WTRU), the method comprising: receiving, by the WTRU, data via at least two downlink (DL) carriers, wherein data is received over each of the at least two DL carriers using orthogonal frequency division multiple access (OFDMA); receiving, by the WTRU, an allocation of a plurality of resources associated with a single uplink control channel associated with a single uplink carrier; determining, by the WTRU, based on the at least two DL carriers, at least one resource of the plurality of resources allocated for the single uplink control channel to use to transmit hybrid automatic repeat request (HARQ) acknowledgment/negative-acknowledgement (ACK/NACK) information for the at least two DL carriers; and transmitting, by the WTRU, the HARQ ACK/NACK information and not channel quality indicator (CQI) information for the at least two DL carriers over the determined at least one resource using the single uplink control channel, wherein a plurality of HARQ ACK/NACKs are aggregated on the single uplink control channel.
