摘要: Provided are a wireless communication method, base station, system and apparatus whereby an interference power is calculated from estimated propagation channel estimation result the transmission controlled based on or suppressed by controlling directivity, thereby increasing capacity. A circuit performs response signal transmitted terminal station estimates result. An calculation measures each of sub-carrier received units, calculates for circuit. When equal to more than predetermined threshold, suppression generation changes generates signal.
