Interference measurement method and apparatus for new carrier type

A base station for supporting interference measurement in a wireless communication system using subframes including, or not including, Cell-specific Reference Signals (CRS), the base station comprising:

• a radio communication unit which transmits and receives subframes to and from a terminal;
• and
• a controller configured to control determining whether a terminal supports a New Carrier Type (NCT) subframe, allocating, when the terminal supports the NCT subframe, Interference Measurement Resources (IMR) to the terminal at Resource Elements (REs) where other signals are not mapped in the subframe, transmitting information on the allocated IMR to the terminal, and transmitting the subframe including the allocated IMR to the terminal.
