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.

摘要： Appropriate data communication is realized. A wireless communication device includes a communication unit and a control unit. The communication unit included in the device performs data transmission to a different device via one of frequency channels classified into a plurality of groups that includes a first group and a second group. On the other hand, the control unit detects a reference signal transmitted from the different device via one of the frequency channels belonging to the first group. The control unit further selects one of the frequency channels for the data transmission from the first group or the second group on the basis of a result of detection of the reference signal.
