发明名称	MULTIPLE INPUT MULTIPLE OUTPUT COMMUNICATION SYSTEM FOR FEEDFORWARDING INTERFERENCE VECTOR INDICATOR
摘要	<p>A multiple input multiple output communication system for feed-forwarding an interference vector indicator is provided to express an interference vector well while reducing the number of bits for the interference vector indicator and exactly predict probability included in a precoding matrix by vectors included in a codebook. A communication method of a base station in a multiple input multiple output communication system comprises the following steps. A precoding vector indicator shows a target precoding vector. The precoding vector indicator is generated(S510). Vectors included in a codebook configure a mapping table of one bit or among bits for an interference vector indicator showing at least one remaining precoding vector. The interference vector indicator shows at least one remaining precoding vector in consideration of probability included in a precoding matrix(S520). The interference vector indicator is produced by using the mapping table(S530).</p>
