The method according to one embodiment includes determining one or more candidate positions for the R-PDCCH; monitoring whether or not the R-PDCCH is being transmitted at the one or more candidate positions; and receiving, through the monitoring that the R-PDCCH is being transmitted, the downlink control information included in the R-PDCCH. The one or more candidate positions are set as a Virtual Resource Block (VRB) set including N VRBs, and a combination of 2 adjacent candidate positions among candidate positions of a lower aggregation level composes one of candidate positions of a higher aggregation level. The VRBs of the VRB set are assigned numbers. Respective candidate positions for the R-PDCCHs of aggregation levels L are determined as VRBs.
