A fixture is isolated from the transmission of vibration emanating from a vibration source by a damper containing magneto-rheological fluid and a plunger mechanically coupling the damper and the fixture. According to the present invention, a processor of a base station device that transmits control information configures a component carrier type for each of a plurality of downlink component carriers in accordance with whether or not each of the plurality of DL CCs can support a relay PDCCH, which is a downlink control channel dedicated to a relay node. In this way, an entire frame assembly is capable of being constructed, adjusted, and readjusted in order to assure each component is oriented in the precisely desired position prior to final closure of the clamping members.
