Abstract
Disclosed is a method for supporting uplink multiple-input and multiple-output (MIMO) in a wireless communication system. A method for transmitting data according to the present invention comprises the steps of: mapping, to first orthogonal frequency division multiplexing (OFDM) symbols within a subframe, first demodulation reference signals (DMRSs) corresponding to a first antenna port and a second DMRSs corresponding to a second antenna port; mapping, to second OFDM symbols except the first OFDM symbols within the subframe, first data corresponding to the first antenna port and second data corresponding to the second antenna port; and transmitting the subframe by using resources allocated to the uplink, wherein predetermined precodings are applied to the first data and the second data, and the predetermined precodings may be changed according to the index of the second OFDM symbols.
