Abstract: A communication device includes transceiver circuitry that transmits a first frame including a request parameter and at least one piece of data for a block acknowledge (ACK); and receives a second frame including a confirmation response to a response parameter and the block ACK. The transceiver circuitry receives a request for the at least one piece of data for the block ACK, transmits the first frame on a basis of occurrence of the request for transmitting the at least one piece of data of the block ACK, and executes transmission of a data frame based on the response parameter included in the received second frame

Abstract: Wireless transmission paths are utilized efficiently. An information processing device includes a control section. If data destined for the own device is received from another device and if there exists undelivered data in the data, the control section performs control to transmit a retransmission request for the data to the other device. If there exists no undelivered data in the data destined for the own device and received from the other device, the control section performs control not to transmit a confirmation of reception.
