SCHEDULING METHOD AND APPARATUS OF MULTI-ANTENNA COMMUNICATION SYSTEM, AND METHOD AND APPARATUS FOR FEEDING-BACK CHANNEL QUALITY INDICATOR

摘要

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.

1. A method for feeding back a channel quality indicator (CQI) by a terminal, the method comprising:
receiving, from a base station, at least one reference signal through at least one of multiple beams of the base station; measuring a signal-to-interference plus noise ratio (SINR) for the at least one reference signal; determining a first level corresponding to the measured SINR among levels of a first CQI; and feeding back the first CQI having the first level to the base station, wherein the first CQI is capable of representing an SINR larger than an SINR which a second CQI used for data transmission of the base station is capable of maximally representing.
