Claim:
1. A method for transmitting a signal, performed by a base station, in a wireless communication system, the method comprising: transmitting a backhaul downlink signal to a relay station through a backhaul downlink transmission subframe, wherein the backhaul downlink transmission subframe includes 14 orthogonal frequency division multiplexing (OFDM) symbols, and wherein if an access downlink transmission subframe, used by the relay station to transmit a signal to a user equipment, and the backhaul downlink transmission subframe are transmitted with a time aligned subframe boundary, OFDM symbols having indices K to 12 are used for transmitting the backhaul downlink signal in a case that the 14 OFDM symbols are indexed 0 to 13, where K is a natural number and 1≦K≦3.
