Abstract
The present invention relates to a method in which a base station transmits a downlink signal using 8 antennas may comprise the steps of: mapping a downlink signal to N (1?N?4) layers; precoding the signal mapped to the N layers by using a specific precoding matrix selected from a pre-stored codebook; subjecting the precoded signal to processing for OFDM symbol generation; and transmitting OFDM symbols through 8 antennas. The pre-stored codebook may comprise precoding matrices for the respective ranks corresponding to N the pre-stored codebook may consist of 16 codebook indexes and a portion of the precoding matrices for high ranks in the 16 codebook indexes may be generated from the precoding matrices for low ranks.
