1. A Mobile Station (MS) operation method for transmitting control information for interference mitigation in a multiple antenna system, the method comprising:

  • determining one of a first Precoding Matrix Index (PMI) and a second PMI for interference from an adjacent Base Station (BS);

    based on a correlation level from correlation values between one of the first PMI and second PMI and the remaining PMIs in the codebook, determining a size of a subset of PMIs; and

    feeding back information indicating the correlation level corresponding the size of a subset of PMIs.
