Method and apparatus for transmitting/receiving control channel

摘要

A method and apparatus for transmitting/receiving control channels through a wireless backhaul in an OFDM-based communication system including relay nodes is provided. A method for transmitting a control channel includes arranging control resources for at least one receiver; sorting the control resources and null resources in a control channel region; rearranging the control resources to be distributed and the null resources to be adjacent to the distributed control resources; and mapping the control resources and null resources to the control channel region.
