Abstract

In a radio relay station, the channel quality of relay links is measured with the use of sounding reference signals from mobile terminals. Feedback information including the measurement results of the channel quality of the relay links is transmitted to a radio base station via a backhaul link. In the radio base station, the channel quality of the direct links is measured with the use of sounding reference signals from the mobile terminals. A correction value from the measurement results of the channel quality from the radio relay station is subtracted. Radio resources are allocated to a mobile terminal based on the measurement results of the channel quality of the direct links and the subtraction results.
