Abstract
Provided is a method for configuring a transmission mode for a backhaul link transmission in a radio communication system including a relay station. The method comprises: a step in which a base station transmits, to the relay station, a relay-physical downlink control channel (R-PDCCH) containing backhaul control information; and a step in which the base station transmits, to the relay station, a relay-physical downlink shared channel (R-PDSCH) containing backhaul data, wherein the R-PDCCH is transmitted in one transmission mode selected from a plurality of predetermined transmission modes, and a reference signal transmitted through the R-PDCCH for the demodulation of the R-PDCCH is determined in accordance with said selected transmission mode.

11. A method of demodulating a signal for a relay node, the method comprising:
-
receiving control information through a relay-physical downlink control channel (R-PDCCH) from an evolved-NodeB (eNB); receiving a data through a relay-physical downlink shared channel (R-PDSCH) from the eNB; and demodulating the control information and the data, wherein when a value of a transmission rank of the R-PDSCH is 2 or more than 2, a reference signal used for a demodulation of the control information is one of a plurality of reference signals used for a demodulation of the data. - View Dependent Claims (12, 13, 14, 15)

16. A relay node, comprising:
-
a radio frequency (RF) unit configured to transmit and receive a radio signal; and a processor connected to the RF unit, wherein the processor is configured for; receiving control information through a relay-physical downlink control channel (R-PDCCH) from an evolved-NodeB (eNB); receiving a data through a relay-physical downlink shared channel (R-PDSCH) from the eNB; and demodulating the control information and the data, wherein when a value of a transmission rank of the R-PDSCH is 2 or more than 2, a reference signal used for a demodulation of the control information is one of a plurality of reference signals used for a demodulation of the data. - View Dependent Claims (17, 18, 19, 20)
