Abstract: Provided is a radio communication device capable of reducing interference, caused by non-SR transmission, with a basic service set (BSS) performing spatial reuse (SR) transmission. An SR transmission resource control unit (107) of the radio communication device (SR initiator) (100) determines transmission resources for an SR signal to be transmitted by means of SR to a second BSS other than a first BSS to which the radio communication device (100) belongs on the basis of radio quality information transmitted from other radio communication devices (SR responders) in the first BSS. A radio transmission/reception unit (101) transmits the SR signal by using the determined transmission resources.
