Of a backhaul link of relay methods on the type of communication system resource allocation and data transmission and reception method and apparatus therethrough

The present invention relates to a downlink signal transmission method and apparatus of a base station in a wireless communication system. Specifically, the R-PDCCH (Relay-Physical Downlink Control contained in the first partition of the step and the sub-frame via the higher layer signaling transmission settings related to the first OFDM (orthogonal frequency division multiplexing) on ​​the partition symbol of the subframe If a and transmitting the CHannel), R-PDCCH contains a DL allocation (downlink assignment), a first partition of the sub-frame characterized in that the set should not be used for transmission PDSCH (Physical downlink Shared CHannel) do.
