Abstract
An algorithm calculates a correction value to be applied to a slot in an adjustment period for power correction. The adjustment period is divided into segments having a plurality of slots, and a target power value is determined for each segment. For each slot, the algorithm determines whether adding a correction value in a given slot would bring the actual accumulative adjustment value closer or farther from the target power value for the segment corresponding to the given slot. The correction value is added to consecutive slots in the segment. The algorithm also checks the total amount of adjustment applied to the slots over a sliding adjustment window to make sure that the total amount of adjustment applied to the slots in the window do not exceed a predetermined maximum threshold.
