Abstract

The present invention relates to a method for transmitting data from a base station to a relay in a system that supports a legacy system.  The method comprises: creating a subframe for the base station to transmit data to the relay; and transmitting the created subframe to the relay, wherein the subframe contains a predetermined number of OFDM symbols, and the base station transmits data to the relay by using certain OFDM symbols of the predetermined number of OFDM symbols, without the use of duplicate OFDM symbols of the OFDM symbols the relay employs in order to transmit a control signal and a reference signal to a legacy user device supported by the legacy system.
