A reverse power control method allows a base station to control transmission power of terminals. To this end, the base station sets a threshold value for the reverse power control, determines the number of the terminals requiring an increase in the transmission power and compares the determined number with the threshold value. If the determined number is equal to or greater than the threshold value, the base station commands the terminals to reduce the transmission power. However, if the determined number is smaller than the threshold value, the base station commands the terminals to increase the transmission power.

DETAILED DESCRIPTION Accordingly, an object of the present invention is to provide a method for allowing a base station to control transmission power of terminals.
The base station determines the number of the terminals requiring the increase in the transmission power and compares it with a threshold value.
If the determined number is equal to or larger than the threshold value, the base station commands the terminals to decrease the transmission power, thereby reducing interference among the terminals.
To achieve the above object, there is provided a reverse power control method for allowing a base station to control transmission power of terminals in a mobile communication system.
To the end, the base station sets a threshold value for the reverse power control, determines the number of the terminals requiring an increase in the transmission power and compares the determined channel number with the threshold value.
If the determined number is equal to or greater than the threshold value, the base station commands the terminals to reduce the transmission power.
However, if the determined number is smaller than the threshold value, the base station commands the terminals to increase the transmission power.
