Abstract: Embodiments for providing a method of controlling timing of a downlink backhaul sub-frame and a relay system for the same are disclosed. According to the present invention, a control signal is transmitted to user equipment during a control symbol period of a sub-frame and a data starting point of the sub-frame is set after a time (SG1) for switching from a transmission mode to a reception mode to receive backhaul data of a base station during a backhaul symbol period. Timing of a transmission sub-frame and a reception sub-frame is delayed by the SG1. A sum of a length of the SG1 and a time (SG2) for switching from the reception mode to the transmission mode is shorter than a length of a symbol having a normal CP. At this time, the lengths of the SG1 and the SG2 are identical to each other or the length of the SG2 is shorter than the length of the SG1. In such a case, the backhaul data are received up to a last symbol period of backhaul symbols of the reception sub-frame.
