In multiuser Multiple-Input Multiple-Output (MIMO) systems in which a base station performs scheduling on the basis of channel information fed back from a plurality of terminals, the user scheduling method of the present invention includes calculating a metric for scheduling the users using the channel information, selecting one of at least two preinstalled scheduling schemes according to the metric, and performing the scheduling with the selected scheduling scheme. The user scheduling method of the present invention performs scheduling with one of TDMA-and STMA-based scheduling schemes which show maximum capacity in different channel environments, such that the system capacity can be optimally maintained even when the channel environment is changed.
