Patent ID: 8068868

Claim:
A method for uplink power alignment estimation by an evolved Node B (eNB) in a communication system, the method comprising the steps of: defining an upper threshold and a lower threshold for a transmit power correction (TPC) level; keeping a total of accumulated TPC commands sent to a user equipment (UE); determining that a power correction is needed; generating a TPC command to be sent to the UE per the needed power correction; 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; sending the TPC command to the UE.
