Abstract

Provided is a method for feeding back a channel quality indicator (CQI) by a terminal. The terminal receives, from a base station, at least one reference signal through at least one of multiple beams of the base station. The terminal measures a signal-to-interference plus noise ratio (SINR) for the at least one reference signal. The terminal determines a first level corresponding to the measured SINR among levels of a first CQI. In addition, the terminal feeds back the first CQI having the first level to the base station.
