Method and apparatus for performing fractional beamforming by large-scale mimo in a wireless communication system

摘要

A method for performing fractional beamforming using a massive antenna array at a Base Station (BS) in a wireless communication system is disclosed. The method includes dividing the massive antenna array by rows or by columns into partitions, receiving feedback information about the partitions from a User Equipment (UE), determining sub-precoders for the partitions based on the feedback information, and transmitting a signal to the UE by performing beamforing using the sub-precoders and a linking precoder that links the partitions to each other.
