Abstract: [Object] To provide a technology capable of performing processing on desired data in the reception-side communication device, even in the case in which a sequence number space is shared among a plurality of pieces of data transmitted from the transmission-side communication device.[Solution] Provided is a transmission control device including: a communication control unit that controls transmission of a plurality of pieces of data including respective sequence numbers; and a data generation unit that generates, as information indicating one or a plurality of pieces of data to be processed in a reception device among the plurality of pieces of data, number information indicating the sequence numbers included in the one or plurality of pieces of data to be processed. The communication control unit controls transmission of the number information to the reception device.

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: 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.

Abstract: A wireless communication device in a wireless network sets management information notification cycles at specified time intervals and transmits management information containing receive timing information showing its own position to start receiving information, receive window information, and receive cycle information. Another wireless communication device receiving that management information links it to a communication device number for the corresponding wireless communication device and stores the receive timing, the receive window information, and the receive cycle information. When sending information, the receive start position of the corresponding communication device is found from the received timing information, the receive window information, and the receive cycle information of the other communication and information is then transmitted at that timing. An asynchronous ad-hoc communication wireless network can therefore be configured without a particular control station.

Abstract translation: 无线网络中的无线通信装置以规定的时间间隔设定管理信息通知周期，并发送包含显示其自身位置的接收定时信息的管理信息，开始接收信息，接收窗口信息和接收周期信息。 接收管理信息的另一无线通信设备将其链接到相应无线通信设备的通信设备号，并存储接收定时，接收窗口信息和接收周期信息。 当发送信息时，从接收到的定时信息中找到对应的通信设备的接收开始位置，然后在该定时发送接收窗口信息和其他通信的接收周期信息和信息。 因此，可以在没有特定控制站的情况下配置异步自组织通信无线网络。
