Abstract:
1. A method for a relay to receive downlink control information from a base station through a Relay-Physical Downlink Control Channel (R-PDCCH), the method comprising: obtaining a candidate position for the R-PDCCH; monitoring whether or not the R-PDCCH is being transmitted at the candidate position; and receiving, through the monitoring that the R-PDCCH is being transmitted, the downlink control information included in the R-PDCCH, wherein the candidate position for the R-PDCCH is set as a Virtual Resource Block (VRB) set including N VRBs, and one candidate position for the R-PDCCH of a higher aggregation level includes a combination of 2 adjacent candidate positions among candidate positions for the R-PDCCH of a lower aggregation level, wherein the VRBs of the VRB set are assigned numbers {n wherein respective candidate positions for the R-PDCCHs of aggregation levels L are determined as VRBs of {n
