To provide a wireless communication method, a wireless communication system, and mobile stations which can easily establish initial access between the mobile stations in D2D communication.
A mobile station 200A transmits to a mobile station 200B a signal for synchronization to be used for establishing initial access to the mobile station 200B on the basis of control information received from a cell to which the mobile station 200A is connected. The mobile station 200B receives the synchronization signal on the basis of the control information received from the cell. Further, the mobile station 200B determines transmission power and transmission timing of a response signal on the basis of the received synchronization signal to transmit the response signal to the mobile station 200A. The mobile station 200A and the mobile station 200B start D2D communication on the basis of the synchronization signal and the response signal.
