Abstract:
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; determining, by the RS, a plurality of uplink (UL) subframes for performing a HARQ with the plurality of allocated DL subframes, each of the plurality of UL subframes corresponding to each of the plurality of allocated DL subframes, assigning, by the RS, sequentially each of a plurality of HARQ processes to each of the plurality of UL subframes one by one; and performing, by the RS, HARQ with the BS at least one of the plurality of HARQ processes assigned to the plurality of UL subframes, wherein a n-th subframe is configured for a corresponding UL subframe if (n−4)-th subframe is configured for one of the plurality of allocated DL subframes, where n denotes an integer, wherein the plurality of allocated DL subframes are configured in at least one radio frame having 10 subframes indexed from wherein subframes of the 10 subframes having indexes
