Method and apparatus for resource allocation in an orthogonal frequency division multiplexing communication system

摘要

A method and Node B are disclosed for allocation of “sticky” resources in an Orthogonal Frequency Division Multiplexing communication system. The Node B comprises a scheduler that is configured to make a sticky resource allocation to a user equipment, determine that a transmit power level allocated for transmissions to the user equipment should be adjusted, determine whether the resources allocated to the user equipment comprise a Quadrature Phase Shift Keying (QPSK) modulation scheme, and in response to determining that the resources allocated to the user equipment comprise a QPSK modulation scheme, adjust the allocated transmit power level without informing the user equipment of the adjustment. The Node B further may condition the determination to adjust the allocated transmit power level without informing the UE of the adjustment based on a size of the adjustment.
