ABSTRACT:
According to the present invention, all terminals can establish synchronization in a radio communications system formed only of a plurality of mobile terminals. This radio terminal communicates by the time division connection method, and comprises a control portion for synchronizing its transmission/reception timing to that of a group including a plurality of radio terminals. The control portion determines the overall cycle including basic cycles in a number corresponding to the number of radio terminals within said group, conducts control to transmit a signal in a basic cycle that is included in said overall cycle and that is set by a unique terminal number allotted in advance to each of said radio terminals, conducts control to receive signals from another radio terminal in another basic cycle, adjusts the transmission/reception timing based on the data received from said other radio terminal in said other basic cycle, and saves the reception timing until a process to adjust the transmission/reception timing is conducted.
