APPARATUS FOR TRANSMITTING AND RECEIVING UPLINK BACKHAUL SIGNAL IN WIRELESS COMMUNICATION SYSTEM AND METHOD THEREOF

摘要

Disclosed are an apparatus for transmitting and receiving an uplink backhaul signal in a wireless communication system and a method thereof. The method for receiving the uplink backhaul signal from a relay station in a base station comprises the step of receiving a signal transmitted through an uplink backhaul sub-frame of an index N in the relay station using an uplink sub-frame of an index N or an index N+1 in the base station. The base station receives the signal transmitted from the relay station in the uplink sub-frame of the index N or the index N+1 of the base station at the delayed timing corresponding to a propagation delay value of the signal according to the distance between the relay station and the base station from a transmitting time point.
