Abstract

Claims (29)

1. A wireless transmit/receive unit (WTRU), comprising:

a receiver;

a transmitter; and

a processor configured to:

receive, via the receiver, configuration information that indicates a plurality of carriers;

determine hybrid automatic repeat request acknowledgement (HARQ ACK) information associated with the plurality of carriers, wherein the HARQ ACK information is determined based on one or more downlink transmissions;

send, via the transmitter, the HARQ ACK information via a single carrier of the plurality of carriers, wherein the HARQ ACK information is sent via an uplink control channel transmission on the single carrier; and

send, via the transmitter, pilot information via the single carrier of the plurality of carriers.

2. The WTRU of claim 1 , wherein the plurality of carriers comprises a primary carrier, and the single carrier of the plurality of carriers is the primary carrier.

3. The WTRU of claim 2 , wherein the plurality of carriers comprises a secondary carrier.

4. The WTRU of claim 1 , wherein the processor is configured to send data via a first carrier of the plurality of the carriers.

5. The WTRU of claim 4 , wherein the processor is configured to send another data via a second carrier of the plurality of the carriers.

6. The WTRU of claim 1 , wherein the plurality of carriers comprises a plurality of uplink carriers and comprises a plurality of downlink carriers, wherein each uplink carrier of the plurality of uplink carriers is paired with a respective downlink carrier of the plurality of downlink carriers.

7. The WTRU of claim 1 , wherein the processor is configured to:

determine each HARQ ACK information associated with a respective carrier of the plurality of carriers; and

send each HARQ ACK information associated with the respective carrier of the plurality of carriers via the single carrier of the plurality of carriers.

8. A method performed by a wireless transmit/receive unit (WTRU), comprising:

the WTRU receiving configuration information that indicates a plurality of carriers;

the WTRU determining hybrid automatic repeat request acknowledgement (HARQ ACK) information associated with a first carrier of the plurality of carriers, wherein the HARQ ACK information is determined based on one or more downlink transmissions;

the WTRU sending the first HARQ ACK information via a single carrier of the plurality of carriers, wherein the HARQ ACK information is sent via an uplink control channel transmission on the single carrier; and

the WTRU sending pilot information via the single carrier of the plurality of carriers.

9. The method of claim 8 , wherein the plurality of carriers comprises a primary carrier, and the single carrier of the plurality of carriers is the primary carrier.

10. The method of claim 9 , wherein the plurality of carriers comprises a secondary carrier.

11. The method of claim 8 , further comprising sending data via a first carrier of the plurality of the carriers.

12. The method of claim 11 , further comprising sending another data via a second carrier of the plurality of the carriers.

13. The method of claim 8 , wherein the plurality of carriers comprises a plurality of uplink carriers and comprises a plurality of downlink carriers, wherein each uplink carrier of the plurality of uplink carriers is paired with a respective downlink carrier of the plurality of downlink carriers.

14. The method of claim 8 , further comprising:

determining each HARQ ACK information associated with a respective carrier of the plurality of carriers; and

sending each HARQ ACK information associated with the respective carrier of the plurality of carriers via the single carrier of the plurality of carriers.
