1. A method for performing a hybrid automatic repeat request (HARQ) in a wireless communication system, the method comprising:
determining, by a relay station (RS), a plurality of allocated downlink (DL) subframes which are used by the RS to receive scheduling information from the BS;
assigning, by the RS, sequentially each of a plurality of uplink HARQ processes to a corresponding one of the plurality of allocated DL subframes one by one; and
performing, by the RS, an uplink HARQ with the BS by using at least one of the plurality of uplink HARQ processes,
wherein the plurality of allocated DL subframes are configured in at least one radio frame having 10 subframes indexed from 0 to 9, and
wherein subframes of the 10 subframes having indexes 0, 4, 5 and 9 are not configured as an allocated DL subframe, and are reserved for BS-to-UE transmission or RS-to-UE transmission.
