RADIO NETWORK SYSTEM, RADIO COMMUNICATION METHOD, AND RADIO COMMUNICATION DEVICE

摘要

There is provided a radio network system including a first terminal for transmitting a transmission request signal containing information on a medium use period to a second terminal before data transmission, receiving a transmission permission signal from the second terminal, and transmitting data to the second terminal during the medium use period, the second terminal for receiving the transmission request signal and transmitting the transmission permission signal, a third terminal receiving a transmission request signal and transmitting data to a fourth terminal during the medium use period, and the fourth terminal. Thus, it is possible to prevent occurrence of a problem that when it is judged that the radio channel is being used, transmission of the station is suppressed.
