Abstract:
A method for feeding back Channel Quality Information (CQI) by a terminal in a Multi-User Multi-Input Multi-Output (MU-MIMO) communication system is provided. The method includes receiving a signal from a base station, determining a lower limit of an average Signal to Interference plus Noise Ratio (SINR) for the received signal, and determining the lower limit of an average SINR as CQI, and feeding back the CQI to the base station.
