A radio communication apparatus includes a control unit for conducting modulation scheme changeover control to change a modulation scheme according to a state of a transmission path and automatic transmitter power control to control a transmission level of another radio communication apparatus to set a reception level of a reception signal to be received by the own apparatus to a predetermined value, wherein the control unit controls, when a changeover is conducted from a first modulation scheme to a second modulation scheme under the modulation scheme changeover control, to keep the transmission level of another radio communication apparatus at a predetermined value under the automatic transmitter power control and conducts, when resetting is conducted from the second modulation scheme to the first modulation scheme under the modulation scheme changeover control, at least one of transmission level reduction control to stepwise lower by a predetermined value the transmission level kept at the predetermined value under the automatic transmitter power control and reception level confirmation control to confirm a state of the reception level for a fixed period of time.
