摘要
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.
