1. A method of transmitting a Relay Physical Downlink Control Channel (R-PDCCH) at a base station (BS) in a wireless communication system, the method comprising: assigning, by the BS, a set of Virtual Resource Blocks (VRBs) for the R-PDCCH to a downlink subframe configured for BS-to-Relay transmission, wherein the set of VRBs is indicated to a relay node by higher layer signaling; and transmitting, by the BS to the relay node, the downlink subframe to carry downlink control information for the relay node, wherein the set of VRBs is configured to be a same VRB set, by higher layer, in a first slot and a second slot of the downlink subframe, wherein if the set of VRBs for the R-PDCCH is assigned in the first slot of the downlink subframe, the R-PDCCH is configured to contain a downlink assignment, and wherein if the set of VRBs for the R-PDCCH is assigned in the second slot of the downlink subframe, the R-PDCCH is configured to contain an uplink grant.
