ABSTRACT:
A radio communication method for transmitting and receiving data between a first terminal and a second terminal comprises the following two steps. A step of establishing a connection between the first terminal and the second terminal when the first terminal and the second terminal have detected that a signal has not been transmitted on a predetermined channel, and the other step of starting data communications between the first terminal and the second terminal which have established the connection, and transmitting the predetermined signal on the predetermined channel from both the first terminal and the second terminal throughout the data communications.
