  • Publication number: 20240137240
    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.

  • Publication number: 20240098574
    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.

  • Patent number: 11533674
    Abstract: 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.
