Abstract

Managing of secondary carriers for a multicarrier user equipment (UE) is described in which the UE initiates or provides input for activation and deactivation of selected secondary cells in a carrier aggregation depending on allocation or provisioning of UE radio frequency resources.

First claim

What is claimed is:

1. A method of wireless communication, comprising:
determining at least one parameter associated with use of a component carrier by a user equipment (UE);
adjusting the at least one parameter to affect an activation status of the component carrier, wherein adjusting the at least one parameter includes varying a reported rank indicator (RI) value from an actual RI value; and
signaling the adjusted parameter to a base station, wherein the adjusting the at least one parameter is made in response to:
identifying, at the UE, one selected from the group consisting of allocating one or more of a plurality of radio frequency (RF) processing chains from a first network to a second network, ending a call on the second network, and updating carrier aggregation capabilities of the UE with a serving base station; and
determining, at the UE and in response to the identifying, to re-provision the one or more of the plurality of RF processing chains of the UE, wherein the determining to re-provision comprises determining to allocate the one or more of the plurality of RF processing chains to the component carrier, or determining to deallocate the one or more of the plurality of RF processing chains from the component carrier.

2. The method of claim 1 , the at least one parameter further including a channel quality indicator (CQI) associated with the component carrier.

3. The method of claim 2 , further including varying the reported CQI value from a measured CQI value in a series of steps.

4. The method of claim 1 , wherein the identifying includes identifying at least one of: the allocating one or more of the plurality of RF processing chains from the first network to the second network, the ending the call on the second network, the updating the carrier aggregation capabilities of the UE with the serving base station, or
determining to re-allocate bandwidth assigned to the UE.

5. The method of claim 1 , further including generating an activation message, wherein the activation message is included in a media access control (MAC) control element.

6. An apparatus of wireless communication, comprising:
means for determining at least one parameter associated with use of a component carrier by a user equipment (UE);
means for adjusting the at least one parameter to affect an activation status of the component carrier, wherein the means for adjusting the at least one parameter includes means for varying a reported rank indicator (RI) value from an actual RI value; and
means for signaling the adjusted parameter to a base station, wherein the means for adjusting the at least one parameter is made in response to:
identifying, at the UE, one selected from the group consisting of allocating one or more of a plurality of radio frequency (RF) processing chains from a first network to a second network, ending a call on the second network, and updating carrier aggregation capabilities of the UE with a serving base station; and
determining, at the UE and in response to the identifying, to re-provision the one or more of the plurality of RF processing chains of the UE, wherein the determining to re-provision comprises determining to allocate the one or more of the plurality of RF processing chains to the component carrier, or determining to deallocate the one or more of the plurality of RF processing chains from the component carrier.

7. The apparatus of claim 6 , the at least one parameter further including a channel quality indicator (CQI) associated with the component carrier.

8. The apparatus of claim 7 , further including varying the reported CQI value from a measured CQI value in a series of steps.

9. The apparatus of claim 6 , wherein the identifying includes identifying at least one of: the allocating one or more of the plurality of RF processing from the first network to the second network, the ending the call on the second network, the updating the carrier aggregation capabilities of the UE with the serving base station, or
determining to re-allocate bandwidth assigned to the UE.

10. The apparatus of claim 6 , further comprising means for generating an activation message, wherein the activation message is included in a media access control (MAC) control element.

11. A computer program product for wireless communications in a wireless network, comprising:
a non-transitory computer-readable medium having program code recorded thereon, the program code comprising program code to cause a computer to:
determine at least one parameter associated with use of a component carrier by a user equipment (UE);
adjust the at least one parameter to affect an activation status of the component carrier, wherein the program code to adjust the at least one parameter includes program code to vary a reported rank indicator (RI) value from an actual RI value; and
signal the adjusted parameter to a base station, wherein the adjustment to the at least one parameter is made in response to:
identifying, at the UE, one selected from the group consisting of allocating one or more of a plurality of radio frequency (RF) processing chains from a first network to a second network, ending a call on the second network, and updating carrier aggregation capabilities of the UE with a serving base station; and
determining, at the UE and in response to the identifying, to re-provision the one or more of the plurality of RF processing chains of the UE, wherein the determining to re-provision comprises determining to allocate the one or more of the plurality of RF processing chains to the component carrier, or determining to deallocate the one or more of the plurality of RF processing chains from the component carrier.

12. The computer program product of claim 11 , wherein the identifying includes identifying at least one of: the allocating one or more of the plurality of RF processing from the first network to the second network, the ending the call on the second network, the updating the carrier aggregation capabilities of the UE with the serving base station, or
determining to re-allocate bandwidth assigned to the UE.

13. The computer program product of claim 11 , further comprising program code to cause the computer to generate an activation message, wherein the activation message is included in a media access control (MAC) control element.

14. An apparatus configured for wireless communication, the apparatus comprising:
at least one processor; and
a memory coupled to said at least one processor,
wherein the at least one processor is configured to:
determine at least one parameter associated with use of a component carrier by a user equipment (UE);
adjust the at least one parameter to affect an activation status of the component carrier, wherein the configuration of the at least one processor to adjust the at least one parameter includes configuration of the at least one processor to vary a reported rank indicator (RI) value from an actual RI value; and
signal the adjusted parameter to a base station, wherein the adjustment to the at least one parameter is made in response to:
identifying, at the UE, one selected from the group consisting of allocating one or more of a plurality of radio frequency (RF) processing chains from a first network to a second network, ending a call on the second network, and updating carrier aggregation capabilities of the UE with a serving base station; and
determining, at the UE and in response to the identifying, to re-provision the one or more of the plurality of RF processing chains of the UE, wherein the determining to re-provision comprises determining to allocate the one or more of the plurality of RF processing ch
