A relay node in a mobile communication network for relaying communications between a base station and a mobile terminal. The relay node includes a communication interface that receives resource allocation information from the base station, the resource allocation information indicating a controllable range of communication resources available to the relay node. The relay node also includes a control unit that controls allocation of resources for communication between the relay node and the mobile station based on the received resource allocation information. The relay node then communicates with the mobile terminal based on the control performed by the control unit.
