Abstract: It is possible to rapidly discover a wireless terminal as a connection partner without preliminarily sharing information related to a scan.A search parameter for searching for a search target wireless terminal is determined depending on preliminarily set correspondence relation from given information. The search processing is performed based on the search parameter to discover the search target wireless terminal. For example, the given information is position information of the wireless terminal, information unique to the search target wireless terminal, and the like. Moreover, the search parameter is a wireless system, a wireless channel, a network identifier, search execution timing, and the like.

Abstract: A communication system is a communication system that includes first and second information processing devices. The first information processing device performs control such that a signal (which is a signal having backward compatibility) serving as an index by which the second information processing device receiving a frame stops the reception of the frame is transmitted to the second information processing device. The second information processing device performs control such that the reception of the frame is stopped based on the signal (which is a signal having backward compatibility) serving as an index by which reception of the frame is stopped when the frame transmitted from the first information processing device is received.

Abstract: Data communication is performed appropriately.An information processing apparatus includes a control unit. In a case of transmitting data by using wireless communication, the control unit performs control of performing transmission while including determination information with which a device in a transmission destination of the data determines in a data link layer whether to pass the data to a higher layer of the data link layer into the data. Also, in a case of receiving data by using wireless communication, the control unit performs control of determining whether to pass the data to a higher layer of a data link layer on the basis of information included in the data (determination information that can be grasped in data link layer).
