Abstract:
1. A method of receiving an uplink (UL) signal from a relay node (RN) in a wireless communication system, the method performed by an eNode B and comprising: receiving a signal transmitted from the relay node, the signal transmitted via an UL subframe of an index N of the relay node and received via an UL subframe of an index N+1 of the eNode B, wherein the signal is received from the relay node at a time delayed from a transmission timing point of the signal by a propagation delay time of the signal due to a distance between the relay node and the eNode B, wherein the signal is received from the relay node according to a first reception mode or a second reception mode such that the signal is received from the relay node via first to eighth symbols of the UL subframe of the index N+1 of the eNode B according to the first reception mode and the signal is received from the relay node via a first slot of the UL subframe of the index N+1 of the eNode B according to the second reception mode.
