RADIO REPEATING DEVICE/METHOD

PROBLEM TO BE SOLVED: To execute repeating between a radio base station and a radio terminal in public PHS service without deteriorating call quality and to simultaneously execute repeating two radio terminals. SOLUTION: In a radio repeating device 3, the time positions of the transmission section and the reception section of a self-radio repeating device are shifted from those of a radio base station by two slots so that a part of the transmission section of the self-radio repeating device is matched with that of the radio base station against the transmission section and the reception section of the radio base station 2 executing communication by repeating the transmission section by four slots and the reception sections (sections (1)-(4)...) by the four slots. Thus, the transmission slot to a device except for the radio repeating device of the radio base station is not overlapped with the reception slot of the radio repeating device, and the transmission slot of the radio repeating device is not overlapped with the reception slot from the radio repeating device of the radio base station. The radio repeating device 3 has two first local oscillators.
