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.

Abstract: A method and device for a transmitting and receiving a signal from a relay station in a radio communication system is provided. The method includes: receiving offset time information from a base station; configuring a time difference between an access downlink transmission subframe that transmits an access downlink signal to a relay station terminal according to the offset time information and a backhaul downlink reception subframe that receives a backhaul downlink signal from the base station; transmitting a control signal from the access downlink transmission subframe to the relay station terminal; and receiving the backhaul downlink signal from the base station in the backhaul downlink reception subframe.
