Abstract: The present invention relates to a method for reporting a channel quality indicator for a relay node-dedicated physical downlink shared channel (R-PDSCH) from a base station by a relay node in a wireless communication system. More particularly, the method comprises the following steps: receiving one or more reference signals from the base station; calculating a channel quality indicator for the R-PDSCH on the basis of one or more reference signals; and reporting the channel quality indicator to the base station. The calculation of the channel quality indicator is performed under the assumption that a specific number (NRE) of available resource elements is included in a subframe in which the R-PDSCH is transmitted. The specific number (NRE) of the available resource elements is determined on the basis of information relating to a last symbol of the R-PDSCH, wherein the starting symbol and the last symbol are set by an upper layer signal.

Abstract: A method is provided for transmitting downlink control information (DCI) at a base station in a wireless communication system. The base station assigns a set of Virtual Resource Blocks (VRBs) for the DCI on a downlink subframe, wherein the DCI is related with a specific device. The base station transmits, to the specific device, the DCI via a specific downlink control channel configured for the specific device by using the downlink subframe. The set of VRBs is configured to be a same VRB set in a first slot and a second slot of the downlink subframe. If the set of VRBs is assigned in the first slot of the downlink subframe, the DCI is configured for a downlink transmission for the specific device. If the set of VRBs is assigned in the second slot of the downlink subframe, the DCI is configured for an uplink transmission for the specific device.
