Abstract

Methods and apparatus for multiple carrier utilization in wireless communications are disclosed. These methods include multiple carrier activation/deactivation, multiple carrier discontinuous transmission (DTX) and discontinuous reception (DRX) activation/deactivation and operations, and multiple carrier acknowledgment/negative acknowledgement feedback. The methods include provisions for joint multiple carrier activation and deactivation and joint DTX and DRX activation and deactivation of multiple carriers.

Claims

1. A method for activating/deactivating multiple carriers, comprising:

receiving an activation/deactivation message, wherein the activation/deactivation message comprises activation/deactivation command information and carrier information;

determining from the activation/deactivation message at least one carrier from the multiple carriers; and

acting on the at least one carrier based on the activation/deactivation message.

2. The method as in claim 1, wherein carrier information is a carrier index.

3. The method as in claim 1, wherein the activation/deactivation message applies to a group of the multiple carriers.

4. The method as in claim 3, wherein the group is determined from at least one of all supplementary carriers, all supplementary carriers in a predetermined frequency band, all downlink supplementary carriers, all downlink supplementary carriers associated with a given downlink anchor carrier, all downlink carriers in a particular frequency band, all downlink non-anchor carriers, all carriers that are part of a predetermined group of carriers, all carriers that are part of a group of carriers having a same radio network temporary identifier.

5. The method as in claim 1, wherein a number represented by the activation/deactivation message indicates the at least one carrier.

6. The method as in claim 1, wherein a carrier carrying the activation/deactivation message indicates the at least one carrier.

7. The method as in claim 1, wherein the activation/deactivation message comprises a predetermined order type that indicates the at least one carrier.

8. The method as in claim 1, wherein the activation/deactivation message is a shared control channel order.

9. The method as in claim 1, wherein the activation/deactivation message applies to carriers that are in a frequency band over which the activation/deactivation message was received.

10. The method as in claim 1, wherein the activation/deactivation message comprises order type reuse with order mapping for indicating the at least one carrier.

11. The method as in claim 1, wherein the activation/deactivation command information and carrier information is mapped to predetermined carriers.

12. A method for handling discontinuous reception (DRX) or discontinuous transmission (DTX) for multiple carriers, comprising:

receiving DRX/DTX configuration parameters applicable to a predetermined group of the multiple carriers; and

configuring for DRX/DTX operation.

13. The method as in claim 12, further comprising:

receiving an activation/deactivation message;

determining from the activation/deactivation message at least one carrier from the multiple carriers; and

acting on the at least one carrier based on the activation/deactivation message.

14. The method as in claim 12, wherein the activation/deactivation message is applicable to a group of the multiple carriers.

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

a receiver configured to receive an activation/deactivation message, wherein the activation/deactivation message comprises activation/deactivation command information and carrier information;

a processor configured to determine from the activation/deactivation message at least one carrier from the multiple carriers; and

the processor further configured to act on the at least one carrier based on the activation/deactivation message.

16. The WTRU as in claim 15, wherein carrier information is a carrier index.

17. The WTRU as in claim 15, wherein the activation/deactivation message applies to a group of the multiple carriers.

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

a receiver configured to receive discontinuous reception (DRX)/discontinuous transmission (DTX) configuration parameters applicable to a predetermined group of the multiple carriers; and

a processor configured to configure DRX/DTX operation.

19. The WTRU as in claim 18, further comprising:

the receiver further configured to receive an activation/deactivation message;

the processor further configured to determine from the activation/deactivation message at least one carrier from the multiple carriers; and

the processor further configured to act on the at least one carrier based on the activation/deactivation message.

20. The WTRU as in claim 18, wherein the activation/deactivation message is applicable to a group of the multiple carriers.
