The mobile station makes a coarse initial estimation of the required transmit
power, based upon the total received power.
•
Problems with Reverse Open Loop Power Control:
• Assumes same exact path loss in both directions; therefore, cannot
account for asymmetrical path loss
• Estimates are based on total power received; therefore the power received
from other cell sites by mobile station introduces inaccuracies
