Apparatus and Method for Changing MIMO Mode in Wireless Communication System

MIMO mode changing apparatus according to one aspect of the present invention to change the MIMO mode for the terminal efficiently is MIMO mode determination unit for determining the current MIMO mode of the terminal; If by the MIMO mode determination unit determining a first MIMO mode for the current MIMO mode of the terminal transmitting the same data through a plurality of antennas, and determining a second first holding time in the first MIMO mode of the UE, the MIMO If it is determined by the mode determining unit in the second MIMO mode for the current MIMO mode for the user terminal transmits a data hold time for each antenna decision unit for determining a second hold time in a MIMO mode of the terminal; And a first holding time of the first critical time or more is maintained MIMO mode change unit to change the MIMO mode of the terminal to the 2 MIMO mode.
