PROBLEM TO BE SOLVED: To provide a radio communication system safe in security for eliminating useless transmission power when a radio base station or a radio terminal communicates with a destination base station or terminal, without performing interference to a radio terminal, etc., other than the destination base station or terminal, and to provide a radio communication method. SOLUTION: The radio communication system 100 comprises mutually radio communication possible communication units 101, 102, 103. The communication unit 102 includes: a receiving part 406 for receiving a signal; and a transmitting part 404 for transmitting a first transmission signal to the communication unit 103 as a destination through the use of electric power to allow the transmission signal to reach both of the communication units 101 and 103 and transmitting a second transmission signal with the communication unit 103 as the destination through the use of the enough electric power to allow the transmission signal to reach the communication unit 103, based on a response signal from the communication unit 103 including information related to the reception power or reception quality of the first transmission signal in the communication unit 103.
