Abstract
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 mobile communication system, radio communication is performed using a carrier having the same frequency in a direct link between a donor cell and a user equipment being served thereby and an access link between a relay node and a user equipment being served thereby. In a backhaul link between the donor cell and the relay node, radio communication is performed using a carrier having a different frequency from that of the carrier used in the direct link and the access link.
