An interference signal control information acquisition method and apparatus for use in the wireless communication system is provided. The interference signal information detection method of a terminal for use in a wireless communication system includes acquiring a first control information part and a second control information part of other users from a received signal, generating a first control information candidate identical in bit length with the first control information part, blindly decoding first control information based on the first control information candidate, and detecting and removing interference signals of the other users from the received signal based on the blindly decoded first control information.
