Abstract

A multi-user Multiple Input Multiple Output (MU-MIMO) communication scheme is provided for a terminal to select a precoding vector from column vectors included in a precoding matrix, and to feed back information associated with the selected precoding vector to a base station. The base station may transmit data to the terminal using the precoding vector.
