Abstract: [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.

Abstract: An information processing apparatus is appropriately connected wirelessly.The information processing apparatus has a wireless communication unit and a controller. The wireless communication unit performs data transmission with another information processing apparatus. It is assumed, while data transmission is being performed between the information processing apparatus and a first information processing apparatus which plays the role of a group owner of a network made up of at least the information processing apparatus and the first information processing apparatus, the information processing apparatus is to newly perform data transmission with a second information processing apparatus. In such a situation, the controller performs a control process to exchange information to change roles for carrying out each data transmission to the first information processing apparatus and the second information processing apparatus.
