- A power controlling device in a mobile communication system, and a method thereof. A base station calculates an average interference of N previous frames, and broadcasts the average interference to subscriber stations. The subscriber stations determine transmission power based on the average interference. Noise and Interference (NI) of frames within a section corresponding to a setting size is calculated (the frames may include a current frame) so an estimated interference is close to the interference generated in the frame in which the subscriber station actually transmits a signal. In addition, to more precisely estimate the NI, the NI of the current frame is compensated according to a value and is broadcast.
