Patent ID: 8824356

Claim:
A method of transmitting control information for a relay node (RN) from an eNode B in a wireless communication system, the method comprising: transmitting, by the eNode B to the RN, information on a resource region of a relay-physical downlink control channel (R-PDCCH), the transmitted information including the control information for the RN; transmitting, by the eNode B to the RN, interleaving mode information indicating an interleaving mode applied to the R-PDCCH, wherein the resource region of the R-PDCCH is specifically configured for the RN, and wherein the interleaving mode information further indicates whether the R-PDCCH is transmitted without being interleaved with at least one other R-PDCCH in a physical resource block (PRB) corresponding to the resource region; and transmitting, by the eNode B to the RN, the R-PDCCH and the at least one other R-PDCCH on the PRB based on the indicated interleaving mode, wherein a transmission start orthogonal frequency division multiplexing (OFDM) symbol index of the R-PDCCH is fixed as an OFDM symbol index 3 in the PRB, and wherein the R-PDCCH is transmitted from an OFDM symbol corresponding to the OFDM symbol index 3 in the PRB.
