2. The WTRU of claim 1 , wherein the transceiver and the processor are configured to receive a second downlink signal on a different downlink carrier and the HARQ ACK/NACK information includes feedback for the second downlink signal.

3. The WTRU of claim 1 , wherein the first uplink control channel signal includes a channel quality indicator (CQI).

4. The WTRU of claim 1 , wherein the plurality of uplink control channel signals includes a second uplink control channel signal, wherein the second uplink control channel signal includes the HARQ ACK/NACK information for the downlink signal.

5. The WTRU of claim 4 , wherein the first uplink control channel signal and the second uplink control channel signal are transmitted in different symbols.

6. A method for use in a wireless transmit/receive unit (WTRU), the method comprising:

receiving an allocation message, wherein the allocation message indicates an allocation of downlink resources for a downlink signal and the allocation message indicates an allocation for a first uplink control channel signal on a first uplink control channel, wherein the indicated allocation for the first uplink control channel indicates a starting symbol for the first uplink control channel signal and subcarriers for the first uplink control channel signal;

receiving the downlink signal on a downlink carrier in the indicated allocation of downlink resources for the downlink signal; and

transmitting a plurality of uplink control channel signals on a plurality of uplink control channels carrying hybrid automatic repeat request (HARQ) acknowledgment/negative-acknowledgement (ACK/NACK) information for the downlink signal and other control information, wherein the plurality of uplink control channels includes the first uplink control channel.

7. The method of claim 6 , further comprising:

receiving a second downlink signal on a different downlink carrier and the HARQ ACK/NACK information includes feedback for the second downlink signal.

8. The method of claim 6 , wherein the first uplink control channel signal includes a channel quality indicator (CQI).

9. The method of claim 6 , wherein the plurality of uplink control channel signals includes a second uplink control channel signal, wherein the second uplink control channel signal includes the HARQ ACK/NACK information for the downlink signal.

10. The method of claim 9 , wherein the first uplink control channel signal and the second uplink control channel signal are transmitted in different symbols.

11. A base station comprising:

a transceiver; and

a processor operatively coupled to the transceiver;

wherein the transceiver and the processor are configured to transmit an allocation message, wherein the allocation message indicates an allocation of downlink resources for a downlink signal and the allocation message indicates an allocation for a first uplink control channel signal on a first uplink control channel, wherein the indicated allocation for the first uplink control channel signal indicates a starting symbol for the first uplink control channel signal and subcarriers for the first uplink control channel signal;

wherein the transceiver and the processor are configured to transmit the downlink signal on a downlink carrier in the indicated allocation of downlink resources for the downlink signal; and

wherein the transceiver is configured to receive a plurality of uplink control channel signals on a plurality of uplink control channels carrying hybrid automatic repeat request (HARQ) acknowledgment/negative-acknowledgement (ACK/NACK) information for the downlink signal and other control information, wherein the plurality of uplink control channels includes the first uplink control channel.

12. The base station of claim 11 , wherein the transceiver and the processor are configured to transmit a second downlink signal on a different downlink carrier and the HARQ ACK/NACK information includes feedback for the second downlink signal.

13. The base station of claim 11 , wherein the first uplink control channel signal includes a channel quality indicator (CQI).

14. The base station of claim 11 , wherein the plurality of uplink control channel signals includes a second uplink control channel, wherein the second uplink control channel signal includes the HARQ ACK/NACK information for the downlink signal.
