초록 ▼

A method for effectively transmitting/receiving a codeword in a MIMO system is disclosed. In a system including a plurality of predetermined rank structures, a reception end transmits rank information (RI), precoding matrix index (PMI), and channel quality information (CQI) of each codeword to a transmission end. The transmission end selects a rank structure on the basis of information received from the reception end. The transmission end selects only some codeword blocks among a plurality of codeword blocks available for the selected rank structure, transmits signals via the selected codeword blocks, and transmits a null signal for the non-selected codeword blocks.

1. A method for transmitting a signal at a transmission end of a Multiple Input Multiple Output (MIMO) system, the method comprising: mapping one codeword for a retransmission among two codewords to N layer among M layers, wherein N and M positive integers, and N is smaller than M, wherein the one codeword was mapped to the N layer when an initial transmission occurs;precoding the N layer based on a precoding matrix predefined for the M layers; andtransmitting the precoded N layer and control information including Modulation Coding Scheme (MCS) values for the one codeword and another codeword of the two codewords to a reception end,wherein the N layer is a portion of the M layers,wherein the one codeword is used for signal transmission and the another codeword is not used for the signal transmission,wherein a transmission power of the N layer is boosted to a transmission power of the M layers,wherein the MCS value for the another codeword is 0, andwherein the MCS value for the one codeword is increased to a value corresponding to the transmission power of the M layers. 2. The method according to claim 1, wherein M is determined on the basis of rank information (RI) reported from the reception end. 3. A transmission end of a multiple input multiple output system, the transmission end comprising: a codeword-to-layer mapping module configured to map one codeword for a retransmission among two codewords to N layer among M layers, wherein N and M are positive integers, and N is smaller than M, wherein the at least one codeword was mapped to the N layer when an initial transmission occurs;a precoding module configured to precode the N layer based on a precoding matrix predefined for the M layers;a transmission module configured to transmit the precoded N layer and control information including Modulation Coding Scheme (MCS) values for the one codeword and another codeword of the two codewords to a reception end,wherein the N layer is a portion of the M layers,wherein the one codeword is used for signal transmission and the another codeword is not used for the signal transmission,wherein a transmission power of the N layer is boosted to a transmission power of the M layers,wherein the MCS value for the another codeword is 0, andwherein the MCS value for the one codeword is increased to a value corresponding to the transmission power of the M layers. 4. The method according to claim 1, wherein N is 1 or 2, and M is 4.
