Abstract

The present aspects relate to enabling a user equipment (UE) to operate in Dual Carrier mode during wireless communication, including generating an event trigger to be transmitted to a network entity in response to the UE satisfying a maximum transmit power threshold value, wherein generating the event trigger initiates a trigger timer that controls when to transmit the event trigger to the network. The aspects further include determining whether a plurality of optimization conditions are met, and modifying a transmission scheme based on the determination that the plurality of optimization conditions are met, wherein modifying the transmission scheme prevents the transmission of the event trigger to the network entity and resets the trigger timer.

First claim

What is claimed is:

1. A method of enabling a user equipment (UE) to operate in Dual Carrier mode during wireless communication, comprising:
generating, at the UE, an event trigger to be transmitted to a network entity from the UE in response to the UE satisfying a maximum transmit power threshold value, wherein generating the event trigger initiates a trigger timer that controls when to transmit the event trigger to the network;
determining, at the UE, whether a plurality of optimization conditions are met, wherein determining whether the plurality of optimization conditions are met further comprises:
determining whether the UE satisfies the event trigger for a transport format indicator on both carriers in the Dual Carrier mode, wherein the transport format indicator is used in the Dual Carrier mode;
determining whether the UE does not satisfy the event trigger for the transport format indicator on one carrier in a Single Carrier mode; and
determining whether a UE control power requirement satisfies a power ratio threshold; and

modifying, at the UE, a transmission scheme based on the determination that the plurality of optimization conditions are met, wherein modifying the transmission scheme prevents the transmission of the event trigger to the network entity from the UE.

2. The method of claim 1 , wherein modifying the transmission scheme occurs based on the determinations that the UE satisfies the event trigger for the transport format indicator on both carriers in the Dual Carrier mode, that the UE does not satisfy the event trigger for the transport format indicator on one carrier in the Single Carrier mode, and that the UE control power requirement satisfies the power ratio threshold.

3. The method of claim 1 , wherein the transport format indicator comprises an Enhanced Dedicated Channel (E-DCH) Transport Format Combination Indication.

4. The method of claim 1 , wherein the UE control power requirement comprises a traffic to pilot (T2P) ratio.

5. The method of claim 1 , wherein modifying the transmission scheme further comprises lowering the transport format indicator on at least one or both carriers in the Dual Carrier mode.

6. The method of claim 1 , wherein modifying the transmission scheme further comprises switching to Discontinuous Transmission (DTX) on at least one or both carriers in the Dual Carrier mode.

7. The method of claim 1 , wherein modifying the transmission scheme further comprises transmitting a buffer indicator to the network entity, wherein the buffer indicator indicates a lower-than-actual amount of data packets in a transmit buffer of the UE.

8. The method of claim 1 , further comprising:
determining that the plurality of optimization conditions are not met;
transmitting the event trigger to the network entity based at least in part on the determination that the plurality of optimization conditions are not met; and
receiving a reconfiguration message from the network entity to switch the UE from Dual Carrier mode to Single Carrier mode, wherein the UE transmits on a single uplink carrier during Single Carrier mode.

9. The method of claim 1 , wherein the event trigger comprises an Event 6D trigger.

10. A non-transitory computer-readable medium storing computer executable code for enabling a user equipment (UE) to operate in Dual Carrier mode for extended periods of time during wireless communication, comprising:
code for generating, at the UE, an event trigger to be transmitted to a network entity from the UE in response to the UE satisfying a maximum transmit power threshold value, wherein generating the event trigger initiates a trigger timer that controls when to transmit the event trigger to the network;
code for determining, at the UE, whether a plurality of optimization conditions are met, wherein the code for determining whether the plurality of optimization conditions are met further comprises:
code for determining whether the UE satisfies the event trigger for a transport format indicator on both carriers in the Dual Carrier mode, wherein the transport format indicator is used in the Dual Carrier mode;
code for determining whether the UE does not satisfy the event trigger for the transport format indicator on one carrier in a Single Carrier mode; and
code for determining whether a UE control power requirement satisfies a power ratio threshold; and

code for modifying, at the UE, a transmission scheme based on the determination that the plurality of optimization conditions are met, wherein modifying the transmission scheme prevents the transmission of the event trigger to the network entity from the UE.

11. An apparatus for enabling a user equipment (UE) to operate in Dual Carrier mode for extended periods of time during wireless communication, comprising:
an event component configured to generate, at the UE, an event trigger to be transmitted to a network entity from the UE in response to the UE satisfying a maximum transmit power threshold value, wherein generating the event trigger initiates a trigger timer that controls when to transmit the event trigger to the network;
a determining component configured to determine, at the UE, whether a plurality of optimization conditions are met, wherein the determining component configured to determine whether the plurality of optimization conditions are met is further configured to:
determine whether the UE satisfies the event trigger for a transport format indicator on both carriers in the Dual Carrier mode, wherein the transport format indicator is used in the Dual Carrier mode;
determine whether the UE does not satisfy the event trigger for the transport format indicator on one carrier in a Single Carrier mode; and
determine whether a UE control power requirement satisfies a power ratio threshold; and

a modifying component configured to modify, at the UE, a transmission scheme based on the determination that the plurality of optimization conditions are met, wherein modifying the transmission scheme prevents the transmission of the event trigger to the network entity from the UE.

12. The apparatus of claim 11 , wherein the modifying component is configured to modify the transmission scheme occurs based on the determinations that the UE satisfies the event trigger for the transport format indicator on both carriers in the Dual Carrier mode, that the UE does not satisfy the event trigger for the transport format indicator on one carrier in the Single Carrier mode, and that the UE control power requirement satisfies the power ratio threshold.

13. The apparatus of claim 11 , wherein the transport format indicator comprises an Enhanced Dedicated Channel (E-DCH) Transport Format Combination Indication.

14. The apparatus of claim 11 , wherein the UE control power requirement comprises a traffic to pilot (T2P) ratio.
