Abstract:
A method of transmitting a signal, performed by a base station, in a wireless communication system. The method according to one embodiment includes transmitting a backhaul downlink signal to a relay station through a backhaul downlink transmission subframe. The backhaul downlink transmission subframe includes 14 orthogonal frequency division multiplexing (OFDM) symbols and the 14 OFDM symbols are indexed 0 to 13. 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, and OFDM symbols having indices K to 12 are used for transmitting the backhaul downlink signal, where K is a natural number and 1≦K≦3.
