Abstract
Disclosed is a method in which a relay node transmits/receives signals via a specific downlink subframe and a specific uplink subframe. The relay node may consider the propagation delay in accordance with the distance between a base station and the relay node to set a subframe timing for transmitting/receiving signals to/from the base station. The relay node may further consider the delay time of 0.5 symbol, 1 symbol or the like in addition to said propagation delay in the event of setting a downlink receiving timing. Setting an uplink subframe timing of the relay node can be divided into the event the timing is set on the basis of a backhaul link and the event the timing is set on the basis of an access link. In the event the timing is set on the basis of the access link, the propagation delay can be double that of the event the timing is set on the basis of the backhaul link, which should be considered in setting the timing.
