Abstract
A method, information processing system, and base station for reshaping power profiles in Orthogonal Frequency Division Multiple Access (OFDMA) symbols. The method includes monitoring a scheduler (116) at a base station (110) for a modulation and coding scheme selection. Determining that the scheduler (116) selected a modulation and coding scheme. Identifying at least one information element (220) within the symbol. Determining, in response to the identifying, a channel connection (210) associated with the at least one information element (220). Determining a channel condition associated with the channel connection (210). Reshaping a power profile associated with the one information element (220). The reshaping decreases power made available to the channel connection (210). Reshaping, in response to the channel condition being less than the channel condition threshold, the power profile associated with the at least one information element (220) so that power made available to the channel connection (210) is increased.
