ABSTRACT:
A radio communication system and the method thereof which can eliminate influence of atmospheric interference or an interference signal having a strong signal level and which can allow repeater transmission without difficulty. A plurality of repeater stations are located between an upper station and a lower station, and each repeater station transmits a TDMA signal whose received signal level exceeds a reference value transmitted from the lower station to the upper station. The upper station generates usage state information for respective time slots of the received TDMA signal, and transmits the usage state information to each repeater station. Each repeater station determines whether or not the corresponding time slot of the TDMA signal to be repeated is used in accordance with the usage state information received from the upper station and, if the time slot is unused, the repeater transmission to the corresponding time slot is allowed. If the time slot is used due to interference from another repeater station, the repeater transmission to the time slot is restrained.
