A multi-user scheduling method and apparatus in a Multiple-Input Multiple-Output (MIMO) system are disclosed. The multi-user scheduling method includes calculating a valid channel norm based on statistical characteristics of a channel for every user terminal, selecting a user set that maximizes the sum of valid channel norms and that includes as many user terminals as data are transmittable to simultaneously, and precoding transmission signals for the user terminals included in the user set according to a predetermined scheme. According to the present invention, the volume of computation required for multi-user selection is reduced greatly, thus making real-time implementation possible. |
