Abstract
To provide a radio relay station apparatus and radio relay method for enabling the radio relay station apparatus to identify a multi-hop relay signal and relay a downlink signal suitably, a first radio relay station apparatus or a radio base station apparatus generates a control signal indicative of passing through a radio relay station apparatus, and transmits the control signal in downlink, and a second radio relay station apparatus receives the control signal, demodulates a downlink signal based on the control signal, modulates the demodulated downlink signal, and transmits the modulated downlink signal.
