摘要： To efficiently use a wireless communication resource. An information processing device includes a communication unit and a control unit. The communication unit transmits a device discovery request signal for performing direct inter-device wireless communication. The control unit changes a detection threshold for detecting a wireless communication signal at timing after transmission of the device discovery request signal. Further, when predetermined information is included when the device discovery request signal for performing direct-inter-device wireless communication is received from another information processing device, the control unit transmits a device discovery response signal to the another information processing device, based on the predetermined information included in the device discovery request signal.
