PROBLEM TO BE SOLVED: To ease dependence of transmission power on a distance between a radio terminal and other radio base stations in the radio terminal connected to a radio base station. SOLUTION: A small cell base station 100 calculates the maximum P(MAX) of transmission power density of an uplink of the radio terminal 200 so that the maximum P(MAX) is proportional to (1-B)th power (B is larger than 0 and is less than 1) of propagation loss PL from the radio terminal 200 to a large cell base station 300 (small cell terminal → large cell base station). Further, the small cell base station 100 decides a transmission power of the radio terminal 200 so that conditions of the calculated P(MAX) are met, and notifies the radio terminal 200 of the transmission power.
