Zusammenfassung:	A method is provided for determining, by a base station, a Virtual-Multiple-Input Multiple-Output (V-MIMO) cluster in a wireless communication system. The base station determines a transmission efficiency of a temporary cluster and selects one or more entry candidate nodes contained in the temporary cluster. The base station determines an entry transmission efficiency. The entry transmission efficiency is a transmission efficiency when the entry candidate node enters a V-MIMO unit cluster. The base station determines whether to make the entry candidate node enter the V-MIMO unit cluster by comparing the entry transmission efficiency with the transmission efficiency of the temporary cluster.
