A radio communication system 1 comprises a picocell base station PeNB placed within a communication area of a macrocell base station MeNB and has transmission output lower than the macrocell base station MeNB. A coverage of the picocell base station PeNB is expanded. A usable resource being a radio resource which a high-power base station is allowed to use as PDSCH is determined on the basis of a degree of expansion of coverage of a low-power base station. |
