    摘要: To appropriately wirelessly connect information processing devices. An information processing device includes a wireless communication unit and a control unit. The wireless communication unit performs media transmission to another information processing device. Further, the control unit that performs control to exchange information in a device discovery process or a capability checking process in a case where the media transmission is newly performed to the second information processing device during the media transmission to the first information processing device. This information is used for deciding a communication path for performing the media transmission to a first information processing device and a second information processing device or a data transmission format used when the media transmission is performed.

    摘要: Upon receiving a beacon, a terminal B sends a RTS control message to a terminal A before sending a registration request message to the terminal A. Upon receiving the RTS control message, the terminal A sends a CTS control message. The terminal B measures the time from when the RTS control message is sent to when the CTS control message is received so as to calculate the distance with the terminal A. If the distance with the terminal A is within a predetermined distance X1, the terminal B sends a registration request message to the terminal A. Similarly, the terminal A measures the distance with the terminal B, and sends a registration request acknowledgement message to the terminal B when the distance with the terminal B is within a predetermined distance X2.

    摘要翻译: 终端B在接收到信标后,向终端A发送注册请求消息之前向终端A发送RTS控制消息。在接收到RTS控制消息后,终端A发送CTS控制消息。 终端B测量从RTS控制消息发送到接收CTS控制消息的时间,以计算与终端A的距离。如果与终端A的距离在预定距离X1内,则终端B 向终端A发送注册请求消息。类似地,终端A测量与终端B的距离,并且当与终端B的距离在预定距离X2内时,向终端B发送注册请求确认消息。
