Method for controling transmission power in cellular system

Transmission power control method of a base station in a cellular system includes at least one step of receiving a reference signal from a surrounding base station, using a received power of a reference signal comprising: estimating a propagation environment between the base station and the neighbor base station and radio waves which is located near the base station to determine the transmit power on the basis of the environment and a step for adjusting the cell area of ​​the base station. Transmit power, a reference signal, the power control
