Abstract
A method and apparatus for uplink power alignment estimation in a communication system includes a stepof defining an upper threshold and a lower threshold for a transmit power correction (TPC) level. A next stepincludes keeping a total of accumulated TPC commands. A next stepincludes determining that a power correction is needed. A next stepincludes generating a TPC command to be sent to a user equipment per the needed power correction. A next stepincludes adjusting the total according to one of the following conditions: if the total is between the upper and lower thresholds then the total is changed per the needed power correction, if the total is at either of the thresholds and the needed power correction would not exceed either of the thresholds then the total is changed per the needed power correction, and if the total is at either of the thresholds and the needed power correction would exceed either of the thresholds then total is kept the same.
