ABSTRACT:
A dedicated short range communications system can warn mutual approach between vehicles having mobile stations installed thereon through dedicated short range communications. Each mobile station includes: a data processing unit that performs data processing of radio transmission signals received by and to be sent from its own mobile station; and an other station allocation determination unit that determines, based on a frame control information slot of the received signal, whether a message data slot of the received signal is allocated to another mobile station. Each mobile station further includes: a message data slot allocation request unit that requests, in an activation slot of the radio transmission signal to be sent, the base station to allocate a message data slot to its own mobile station; and a warning command unit that generates a warning command when a message data slot of the received signal is allocated to another mobile station.
