Abstract
An interference power measuring circuit in a base station measures the interference power in a cell that the base station belongs to. When the measured interference power is larger than a predetermined value, the transmitter in the base station transmits the interference information for each frequency used in the FDMA communication system to a base station in a neighboring cell. The base station in the neighboring cell instructs user equipment that communicates the base station to reduce a transmission power.
