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.
