<p>Disclosed is a multi-input multi-output communications method in a large-scale antenna system. An MIMO transmission method includes a step of obtaining channel information on a terminal, a step of dividing the terminal into a class and a group subject to the class, based on the channel information, a step of deciding a group beam forming matrix with the group, a step of performing the group beam forming transmission on terminals included in the group based on the group beam forming matrix, a step of obtaining single Su-CQI information and interference signal information with regard to the terminals included in the group, a step of scheduling the terminals based on the Su-CQI information and interference signal information, and a step of transmitting data to the terminals based on the scheduling. Therefore, the amount of the feedback of the channel condition information can be reduced.</p> |
