Radio communication system and communication method

A communication method in a communication system comprising a plurality of communication nodes which includes a base station and a plurality of relay nodes, wherein the base station controls the relay nodes, each of which can provide a radio connection to at least one terminal via an access link, the communication method comprising:

• at the base station,
• signaling each of the relay nodes to report measurement information related to the access link;
• and
• receiving a report on the measurement information from each relay node.

A relay node device in a communication system comprising a plurality of communication node devices including a base station and a plurality of relay node devices, comprising:

• a first radio communication section for providing a first radio connection to the base station via a first link;
• a second radio communication section for providing a second radio connection to at least one terminal via a second link;
• and
• a controller for generating a report on measurement information related to the second link and sending the report to the base station according to signaling from the base station.
