摘要
Improvement of use efficiency of radio resources is realizable.An information processing device is an information processing device which includes a reception unit and a control unit. The reception unit included in this information processing device is a reception unit which receives a packet. In addition, the control unit included in the information processing device is a control unit which controls a packet monitoring state of the information processing device in case of detection of reception of a packet not addressed to the information processing device. The packet monitoring state is controlled on the basis of reception power at the time of reception of the packet not addressed to the information processing device.
