Abstract
A method and apparatus for transmitting and receiving a Relay Physical Downlink Control Channel (R-PDCCH) being a control channel for a relay node (RN) in a wireless communication system are disclosed. To transmit an R-PDCCH to a RN, a BS includes a processor for interleaving a predetermined number of Control Channel Elements (CCEs), mapping the interleaved CCEs to at least one Virtual Resource Block (VRB) configured for R-PDCCH transmission, mapping the at least one VRB to at least one Physical Resource Block (PRB), and a transmitter for transmitting the R-PDCCH to the RN through the at least one PRB.
