A base station receives a pilot signal and position information on each of a plurality of mobile stations from the each mobile station. An uplink pilot signal separating unit separates the pilot signal of the each mobile station. A received uplink signal quality calculating unit calculates received signal information on the each mobile station based on the pilot signal of the each mobile station. A position information extracting unit extracts the position information on the each mobile station. A propagation information generating unit generates map information representing the received signal quality at every location by making the position information on the each mobile station correspond to the received signal quality information on the each mobile station. The base station transmits the map information to the each mobile station, and the each mobile station displays the map information.
