Abstract: Exchange of data is performed appropriately. An information processing apparatus is an information processing apparatus that includes a control unit. The control unit included in the information processing apparatus performs control for adding, to request information for requesting a different apparatus for a confirmation response to a plurality of data transmitted to the different apparatus, notification information. The notification information is information regarding at least sequence numbers other than a start sequence number from among sequence numbers corresponding to the plurality of data. Further, the control unit transmits the request information, to which the notification information is added, to the different apparatus.

Abstract: A communication apparatus including: a control unit that performs setting related to a transmission resource depending on a communication parameter decided on the basis of signal power information varying in accordance with a transmit power level; and a communication unit that transmits a frame in accordance with the setting related to the transmission resource. The communication apparatus, a communication method, and a program can equalize communication efficiencies of a plurality of communication apparatuses while maintaining or enhancing overall communication efficiency of a communication system composed of the plurality of communication apparatuses.

Abstract: Modes on power consumption are suitably set. There is provided an information processing device including a control section. When the information processing device in a first mode transitions to a second mode in which the information processing device consumes power differently than in the first mode, the control section performs control to transmit at least one frame. Upon transmitting the frame, the control section inserts into the frame information for notifying a first device compatible with the second mode that the information processing device will transition to the second mode, and information for causing a second device incompatible with the second mode to suppress transmission.
