A mobile station 200A transmits a synchronization-use signal to be used for establishment of initial access with a mobile station 200B toward 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-use signal on the basis of the control information received from the cell. Moreover, the mobile station 200B determines transmission power and a transmission timing of a response signal on the basis of the received synchronization-use signal, and transmits the response signal toward the mobile station 200A. The mobile station 200A and the mobile station 200B start D2D communication on the basis of the synchronization-use signal and the response signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio communication method, radio communication system, and mobile station","description":"Provided are a radio communication method, a radio communication system, and a mobile station, by which it is possible to easily establish initial access between mobile stations in D2D communication.
