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.
