1. A method for performing power control in a communication system, the method comprising:
- adjusting a predetermined power control threshold value for a first mobile communication terminal for low rate data or voice data based on a communication environment condition of a second mobile communication terminal for higher rate data than a predetermined rate data, in case that the second mobile communication terminal is scheduled for a next frame; and
transmitting a power control command to the first mobile communication terminal, the transmitted power control command being based on the adjusted-predetermined power control threshold value.

Abstract
A method of performing power control in a mobile communication system is disclosed. In the method, power control information is transmitted to a terminal by using a terminal power control threshold of the terminal being changed in due consideration of a communication circumstance in case of that a high-speed data transmission terminal is scheduled during receiving low-speed and voice data from the terminal.
