Abstract
Systems and methodologies are described that facilitate power distribution and data allocation in a multi-carrier wireless communication system. A portion of transmit power can be pre-allocated to an anchor carrier to support non-scheduled data flows. Remaining power is split among all carriers including the anchor carrier after pre-allocation. Data from one or more flows scheduled and non-scheduled are allocated to the carriers in accordance with priorities associated with the one or more flows. Allocation of data can be performed sequentially starting with a non-anchor carrier. In addition non-scheduled data flows can be restricted to the anchor carrier.

Claim
1. A method, comprising: pre-allocating a portion of transmit power to a first carrier in a plurality of carriers, wherein the first carrier is an anchor carrier; distributing remaining transmit power, after pre-allocation of the portion, between at least the first carrier and a second carrier of the plurality of carriers; sequentially allocating data from one or more data flows to at least the first carrier and the second carrier, wherein allocation starts with the second carrier, wherein the second carrier is a non-anchor carrier.
2. The method of claim 1 , wherein pre-allocating the portion of transmit power comprises determining the portion of transmit power based upon data requirements of a non-scheduled data flow.
3. The method of claim 2, wherein the portion of transmit power includes power required for a control channel associated with the non-scheduled data flow.
4. The method of claim 2, wherein the portion of transmit power comprises a minimum power among a remaining power available, a power necessary to transmit data up to a non-scheduled grant associated with the non-scheduled data flow, and a power necessary to transmit all data in the non-scheduled data flow.
5. The method of claim 1, further comprising allocating data from a non-scheduled data flow to the first carrier.
6. The method of claim 5, wherein allocating data from the non-scheduled data flow comprises filling a protocol data unit associated with the first carrier with data from the non-scheduled data flow in accordance with at least one of a size of the protocol data unit, a non-scheduled grant, an amount of data in a queue associated with the non-scheduled data flow.
7. The method of claim 1, wherein allocating data from one or more data flows comprises serving the one or more data flows in accordance with priorities associated with the one or more data flows, wherein the one or more data flows are served from a highest priority to a lowest priority.
8. The method of claim 1, further comprising: identifying a first set of supported packet formats associated with the first carrier; and identifying a second set of supported packet formats associated with the second carrier, wherein the first set of supported packet formats and the second set of supported packet formats are identified based upon an amount of power distributed to respective carriers.
9. The method of claim 8, wherein the first set of supported packet formats and the second set of supported packet formats are identified every transmission time interval
10. The method of claim 8, wherein allocating data from one or more data flows to the first carrier comprises filling a protocol data unit in accordance with at least one of the first set of supported packet formats, a serving grant associated with the first carrier, or the amount of power distributed to the first carrier
11. The method of claim 8, wherein allocating data from one or more data flows to the second carrier comprises filling a protocol data unit in accordance with at least one of the second set of supported packet formats, a serving grant associated with the second carrier, or the amount of power distributed to the second carrier
12. The method of claim 1 , wherein distributing remaining transmit power comprises: identifying a first maximum transmit power for the first carrier, wherein the first maximum transmit power includes a first amount of power distributed from remaining transmit power and the portion of transmit power pre-allocated to the first carrier; and identifying a second maximum transmit power for the second carrier, wherein the second maximum transmit power include a second amount of power distributed from remaining transmit power
13. The method of claim 12, further comprising: determining a first normalized remaining power margin for the first carrier based at least in part on the first maximum transmit power; and determining a second normalized remaining power margin for the second carrier based at least in part on the second maximum transmit power
14. The method of claim 13, further comprising employing the first normalized remaining power margin and the second normalized remaining power margin in at least one of enhanced dedicated channel (E-DCH) transport format combination (E-TFC) restriction or Happy Bit generation
15. The method of claim 1 , wherein distributing remaining transmit power comprises employing a sequential power split mechanism
16. The method of claim 1 , wherein distributing remaining transmit power comprises employing a parallel power split mechanism
17. The method of claim 1 , wherein distributing remaining transmit power further comprises: identifying a retransmission carrier in the plurality of carriers, wherein the retransmission carrier is associated with a retransmission; and allocating an amount of power to the retransmission carrier, wherein the amount of power is a power required for the retransmission
18. The method of claim 17, further comprising distributing, to remaining carriers in the plurality of carriers, any power remaining after allocation of power to the retransmission, wherein power remaining after allocation of power to the retransmission includes the portion of transmit power pre-allocated
19. A wireless communications apparatus, comprising: at least one processor configured to: reserve a portion of transmit power to an anchor carrier in a multi-carrier uplink configuration, wherein the portion of transmit power is based upon data requirements of at least one non-scheduled data flow; split remaining transmit power, after power reservation to the anchor carrier, among a plurality of carriers including the anchor carrier; and fill a plurality of protocol data units respectively associated with the plurality of carriers with data from a plurality of data flows in accordance with priorities associated with the plurality of data flows.
