  • Patent number: 10531400
    Abstract: An information processing apparatus includes a control part. The control part performs control to transmit a frame for requesting the transmission of data to an information processing apparatus as a destination of the data and for requesting information processing apparatuses other than the information processing apparatus as the destination to set a transmission inhibition time, the frame being transmitted with transmitting power determined on the basis of surrounding environment information regarding an environment surrounding the information processing apparatus transmitting the frame. Transmission of the frame causes the transmission inhibition time to be set over an appropriate range of information processing apparatuses. Efficiency of utilization of communication resources is improved by suitably setting a transmission inhibition time.

  • Publication number: 20190342861
    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 seeding information, the receive start position of the corresponding communication device is found from the receive 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.

  • Patent number: 10454622
    Abstract: A radio transmission apparatus and a radio transmission method for readily controlling retransmission timing presets a frame cycle for retransmission, and transmits only packets for which no acknowledgement of receipt has been received within the frame cycle as a reply from a receiving apparatus to a transmitting apparatus. Thus, timing for retransmission can be readily determined. Also, the retransmission timing is determined based on when a packet is actually transmitted. Therefore, the multiple acknowledgement of receipt can be returned as a combined reply.

  • Publication number: 20190289601
    Abstract: A wireless communication network that forms an ad-hoc network without the arrangement of a controlling station sets a period that a communication apparatus can utilize with priority and performs isochronous communication in the period as required. When isochronous communication has not been performed or after isochronous communication has finished in the priority utilization period, other communication apparatuses perform arbitrary communication. When another communication is performed in a communication apparatus's own priority utilization period, the start of isochronous communication is temporarily delayed. In an ad-hoc communication environment, data having a real-time characteristic, such as AV content, can be efficiently transmitted through the isochronous communication.
