A wireless communication system includes a plurality of terminal apparatuses that perform communication using a first frequency band in which communication based on a random access scheme is performed and a second frequency band which is different from the first frequency band, a first base station apparatus that performs communication using the first frequency band, a second base station apparatus that performs communication using the second frequency band, and a cooperation control apparatus that selects a terminal apparatus that transmits user data via the first base station apparatus from among the plurality of terminal apparatuses based on information acquired by the first base station apparatus and the second base station apparatus. The cooperation control apparatus selects which of the first base station apparatus and the selected terminal apparatus acquires access right for transmission of the user data via the first base station apparatus, and notifies the selected terminal apparatus and the first base station apparatus of the selection result.
