A base station, a radio communication system and radio communication method

The base station includes a measurement unit and a setting unit. Absolute value measuring unit measures the total received power in the cell, the discrete value of the total received power in a cell, a cell that is a ratio of successfully received packet reception success rate, cell and the number of wireless terminals connected simultaneously, i.e. the number of users simultaneously connected at least one information. Setting unit based on the information measured by the measurement unit, the total received power is set to be equal to the target in a cell, i.e., the target received power.
