Abstract: A method and apparatus is provided for determining a modulation and coding scheme in a Multiple Input Multiple Output system with a Maximum Likelihood Detector (MIMO-MLD), in which an upper bound and a lower bound of a Signal to Noise Ratio (SNR) for the MIMO-MLD are determined, an effective Signal to Noise Ratio (eSNR) is computed using a relation between the upper bound and the lower bound, a channel quality is estimated using the eSNR, and a modulation and coding scheme is determined using the estimated channel quality.

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.

Abstract: An achievable sum data rate with respect to each of available candidate transmission/reception modes may be calculated to select a transmission/reception mode of transmission/reception pairs repeatedly using radio resources. A transmission/reception mode to be applied may be selected from the candidate transmission/reception modes based on the calculated sum data rate. Information associated with the selected transmission/reception mode may be shared by the transmission/reception pairs.
