摘要
A method for transmitting feedback information for fractional beamforming using a massive antenna array from a User Equipment (UE) to a Base Station (BS) in a wireless communication system is disclosed. The method includes receiving information about a plurality of Reference Signal (RS) resources from the BS; selecting at least one of a sub-precoder for at least one RS resources, and one linking precoder for linking the RS resources, based on a preset codebook; and reporting information about the selected precoder to the BS. The selected precoder is one precoding matrix of precoding matrices included in the codebook or a permuted form of the one precoding matrix, and the information about the selected precoder includes an index and permutation information of the one precoding matrix.
