摘要： Provided are a base station configured to provide an interference vector indicator to a terminal, and the terminal configured to recognize at least one remaining precoding vector using the interference vector indicator. Each of the base station and the terminal may configure a mapping table between at least one bit for the interference vector indicator indicating the at least one remaining precoding vector, and a plurality of vectors included in a codebook, based on a probability that the plurality of vectors may be included in a precoding matrix. In this instance, the base station may generate the interference vector indicator using the mapping table, and the terminal may recognize the at least one remaining precoding vector using the mapping table. The mapping table may be differently configured according to various modes.
