Abstract: A wireless resource is utilized efficiently.An information processing apparatus is an information processing apparatus that includes a control unit. The control unit provided in the information processing apparatus performs control for aborting, when a packet decided to be transmitted from a second network different from a first network to which the own apparatus belongs is detected, reception of the packet. Further, the control unit provided in the information processing apparatus performs control for dealing with carrier sense as an idle state based on a reception strength of the packet decided to be transmitted from the second network.

Abstract: To efficiently use radio resources.An information processing device is an information processing device that receives a packet. The information processing device is an information processing device that includes a control unit. The control unit included in the information processing device performs control such that reception of a packet is stopped during the reception according to a first condition. The control unit included in the information processing device performs control such that reception of the packet is stopped during the reception and an operation is performed assuming that a carrier sense is an idle state for a time from start of the reception of the packet to stop of the reception of the packet according to a second condition.

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: 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.
