Abstract:
A radio communication repeater control method in which a plurality of repeater stations are intervened between an upper station and a lower station, each repeater station transmits a TDMA signal whose receiving signal level exceeds a reference value transmitted from the lower station to the upper station whereinsaid upper station generates a usage state information of respective time slots of said received TDMA signal and transmits the usage state information to each repeater station,each repeater station judges whether or not the corresponding time slot of the TDMA signal to be repeated is used in accordance with said usage state information received from said upper station, a repeater transmission to the time slot is allowed if the time slot is unused, the repeater transmission to the time slot is restrained if the time slot is used due to other repeater station, wherein each repeater stationi) generates a first binary signal of the corresponding logical value to whether or not a received burst signal to the time slot exists when the time slot of the TDMA signal is unused;ii) generates a second binary signal of the corresponding logical value to whether or not the received burst signal just before the change exists when the change of the time slot from an unused state to a used state is detected; andiii) generates a third binary signal of the corresponding logical value to the unused state and the used state of the time slot, whereby the repeater transmission to the time slot is allowed or restrained in accordance with a combination of the logical values of the first to third binary signals.
