Abstract
Provided is a radio communication system including a plurality of base stations and a repeater apparatus, in which the repeater apparatus amplifies and transmits a radio signal received from at least one of the plurality of base stations, and controls a domain in which the radio signal is transmitted based on a traffic amount of each of the plurality of base stations. Accordingly, the number of installed base stations which are costly is reduced, and an operating rate of the respective base stations is gained along with the decrease in number of installed base stations.

8. A repeater apparatus which comprises a plurality of antennas and relays a communication between at least one base station and at least one mobile station using a radio signal,
wherein at least one of the plurality of antennas is a repeater sector on the base station side antenna that transmits and receives the radio signal with respect to the at least one base station, and at least one of the plurality of antennas is a repeater sector antenna on the mobile station side that transmits and receives the radio signal with respect to the at least one mobile station; - and
wherein the repeater apparatus includes; at least one switch that changes over a connection between the antenna that receives the radio signal and the antenna that transmits the radio signal received by the one of the antenna that receives the radio signal; at least one amplifier that amplifies the radio signal to be transmitted from the antenna; and an input-output control unit that controls the at least one switch and the at least one amplifier. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
