Abstract
A method and apparatus for reporting Channel State Information (CSI) by a User Equipment (UE), for fractional beamforming using a massive antenna array of a Base Station (BS) in a wireless communication system are disclosed. The method includes receiving information about a plurality of Reference Signal (RS) resources from the BS, generating CSI including a sub-precoder for at least one of the plurality of RS resources, and a Channel Quality Indicator (CQI) and a Rank Indicator (RI) for all of the plurality of RS resources, and reporting the CSI to the BS. The massive antenna array is divided by rows or columns into partitions and the plurality of RS resources correspond to the partitions.
