ABSTRACT:
An enhanced closed-loop power control method includes the steps of: setting an initial value of a power control variable; detecting a strength of a terminal signal and comparing the detected strength with a reference Eb/No; transmitting a power control signal to a terminal according to the comparison result and the set power control variable value; and analyzing the power control signal transmitted to the terminal for a predetermined reference time period and resetting a power control variable. When the subscriber does not move in an area with a favorable radio reception sensitivity (that is, in a state that the Eb/No is a little changed) the base station sets the power control step-size lower than the current step-size and performs a fine power control. Thus, a flux of the transmission power can be prevented. And, since the number of puncturings performed per unit time is reduced, the data transmission efficiency can be heightened.
