Abstract: A method for transmitting channel quality information (CQI) in a MIMO system is provided that allows a receiver to feed back a CQI value to a transmitter. The method includes receiving a transmission (Tx) pilot signal for each Tx antenna from a base station (BS), measuring a first CQI value of a first codeword and a second CQI value of a second codeword based on the pilot signal, and transmitting the first CQI value of the first codeword and the second CQI value of the second codeword to the BS where at least the first or second CQI value includes specific information capable of indicating a transmission restriction status of a corresponding codeword.

Abstract: A method for transmitting downlink control information and a method for generating a codeword for the same are disclosed. In generating a long code having a low code rate, a basic code of which minimum distance between codes is maximized is repeated by a prescribed number of times and bits of the repeated code are adjusted. Therefore, a minimum distance condition between codes of a long code is satisfied and simultaneously the code be simply generated.

Abstract: A method and terminal apparatus are described for performing channel interleaving at a terminal in a multiple-input multiple-output (MIMO) wireless communication system. A number of columns C of an interleaver matrix are assigned as a number of symbols for transmitting data per subframe (Nsymb). A number of rows R of the interleaver matrix is defined as H · L · log 2 ⁢ Q C , where H is a number of modulation symbols per layer, L is a number of layers and Q is a modulation order. Input vector sequences are written into entries of the interleaver matrix, row by row. Each of the entries has a size of L·log2 Q bits. Output bit sequences are generated by reading out the entries of the interleaver matrix, column by column. The output bit sequences are modulated by a unit of log2 Q bits, to generate modulation symbols. The modulation symbols are mapped to the L layers, and transmitted by using the L layers.

Abstract: A method for transmitting feedback information via a Spatial Rank Index (SRI) channel includes determining, at an access terminal, a value of a spatial rank index and transmitting, from the access terminal through the SRI channel, feedback information indicating the determined value of the spatial rank index according to a prescribed coding. The codeword of the prescribed coding is one of: (0,0,0,0,0,0,0,0), (1,0,1,0,1,1,0,1), (0,1,1,1,0,0,1,1), or (1,1,0,1,1,1,1,0).
