Abstract
The present invention relates to a method by which a base station performs multiple input and multiple output (MIMO) transmission using antennas of a plurality of cells in a multi-cell wireless communication system, the method comprising the steps of: selecting a rank value and cells for downlink MIMO transmission of a terminal on the basis of measurement information of the base station and the terminal, and determining a precoding matrix according to the rank value; and generating data which is to be transmitted to the terminal as data streams corresponding to the selected rank value, and mapping the data streams to antennas of the selected cells through a precoder so as to transmit the data streams to the terminal.
