MOBILE COMMUNICATION SYSTEM

摘要

An object of the present invention is to provide a mobile communication system capable of preventing interference in a communication system as well as reducing the load of a user equipment in a search operation. In the present invention, radio communication is performed using a carrier having the same frequency in a direct link (1307) between a donor cell (1301) and a user equipment (1304) being served thereby and an access link (1306) between a relay node (1302) and a user equipment (1303) being served thereby. In a backhaul link (1305) between the donor cell (1301) and the relay node (1302), radio communication is performed using a carrier having a different frequency from that of the carrier used in the direct link (1307) and the access link (1306).
