    摘要: A method for generating a downlink signal in a downlink MIMO (Multiple Input Multiple Output) comprises the steps of: mapping at least one transport block to at least one codeword; mapping at least one layer to each codeword; classifying at least one layer mapped to each codeword into a certain number of layer groups and performing layer permutation by the layer groups; and generating an OFDM (Orthogonal Frequency-Division Multiplexing) symbol using a signal which is permutated by the layer groups. A CRC (Cyclic Redundancy Check) is attached by the layer groups.

    摘要: An apparatus and method of transmitting ACK/NACK (acknowledgement/negative ACK) information in downlink and an apparatus and method of receiving the ACK/NACK information are disclosed. The present invention configures ACK/NACK information on multiple UL codeword transmission using a PHICH and at least one NDI, whereby the ACK/NACK information on the multiple UL codeword transmission is transmitted to a user equipment without additional PHICH resource allocation. The present invention extends the conventional HI codeword and/or arranged position on a signal constellation, thereby transmitting ACK/NACK information on multiple UL codeword transmission to a user equipment without additional PHICH resource allocation.

    摘要: An apparatus and method for a precoding matrix are disclosed. A codebook used for selecting a precoding matrix is comprised of m subgroups each including n precoding matrices. A user equipment indicates a specific precoding matrix selected from the codebook by transmitting to a base station a first codebook index indicating one of the m subgroups and a second codebook index indicating one of n precoding matrices in a subgroup. The base station configures the specific precoding matrix from the codebook based on the first and second codebook indexes.
