摘要： An apparatus and method for transmitting and receiving a demodulation reference signal (DM RS) are disclosed. A method for controlling a base station (BS) to transmit a demodulation reference signal (Demodulation RS or DM RS) in a wireless communication system includes transmitting, by the base station (BS), a DM RS for a relay node (RN) to the relay node (RN) through a specific backhaul subframe to which an extended cyclic prefix (CP) is applied. The DM RS is transmitted over two resource elements (REs) of individual subcarriers having subcarrier frequency indexes 2, 5, 8 and 11 in a frequency axis within a second slot of the specific backhaul subframe.
