Abstract: A wireless communications system is configured to perform wireless communication by using a first band dedicated to the system and a second band shared by the system and another wireless communications system. The system includes a base station configured to transmit in the first band to a terminal when detecting an available carrier wave of the second band, a control signal permitting data transmission in the second band from the terminal to the base station, the base station continuously sending out a radio wave of the second band during a period until the data transmission; and the terminal configured to perform the data transmission after a predetermined time from transmission of the control signal by the base station.

Abstract: A wireless communication system includes a plurality of wireless stations including a first wireless station, a second wireless station, and a third wireless station. The wireless communication system further includes a first controller that obtains a transmission timing at which the third wireless station transmits first notification information to the second wireless station, the first notification information indicating that the third wireless station is to communicate with the second wireless station; and a first communicator that transmits second notification information to the second wireless station at the obtained transmission timing, the second notification information indicating that the first wireless station is to directly communicate with the second wireless station.
