摘要： An information processing apparatus including a control unit. In a case where a first physical layer network identifier for identifying a first network to which an apparatus in question belongs is determined to match a second physical layer network identifier for identifying a second network to which the apparatus in question does not belong, the control unit changes a first physical layer network identifier. Then, the control unit transmits the change information relating to the change to another information processing apparatus. Further, in a case where change information for changing a first physical layer network identifier for identifying a first network to which the apparatus in question belongs is received from another information processing apparatus which belongs to the first network, the control unit changes a condition for terminating reception processing of a packet on the basis of the change information in a middle of the reception processing.

摘要： [Object] To improve the reliability by using an acknowledgement response while using radio resources efficiently in multicast transmission over wireless transmission.[Solution] A plurality of wireless communication devices included in a multicast group, when receiving a data frame, transmit simultaneously an acknowledgement response of multicast using spatial multiplexing in response to an acknowledgement request from a transmission source. On the other hand, a wireless communication device of the transmission source decomposes the acknowledgement responses simultaneously received into the original individual acknowledgement responses and restores them using signal processing based on information on a channel with each wireless communication device of a transmission destination.

摘要： 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.
