Radio relay station apparatus and radio relay method

A radio relay method for relaying a radio signal in a radio relay station apparatus that relays the radio signal between a base station apparatus and a mobile station apparatus, the radio relay method comprising;

• storing an identifier of the mobile station apparatus;
• specifying a radio resource assigned to the mobile station apparatus, which is a radio resource in which a radio signal that should be amplified is transmitted, the radio resource assigned to the mobile station apparatus being indicated by control channel information sent from the base station apparatus;
• receiving the radio signal between the base station apparatus and the mobile station apparatus;
• amplifying the received signal, the received signal being transmitted on the radio resource specified as the radio resource in which the radio signal that should be amplified is transmitted;
• and
• sending the amplified signal in a form of the radio signal.

A radio communication system comprising:

• a base station apparatus;
• a mobile station apparatus;
• a radio relay station apparatus that relays a radio signal between the base station apparatus and the mobile station apparatus,
• wherein the radio relay station apparatus stores an identifier of the mobile station apparatus,
• specifies a radio resource assigned to the mobile station apparatus, which is a radio resource in which a radio signal that should be amplified is transmitted, the radio resource assigned to the mobile station apparatus being indicated by control channel information sent from the base station apparatus,
• receives the radio signal between the base station apparatus and the mobile station apparatus,
• amplifies the received signal, the received signal being transmitted on the radio resource specified as the radio resource in which the radio signal that should be amplified is transmitted, and
