    摘要： Disclosed is a method for transmitting a CoMP reference signal for accurate channel estimation. The CoMP reference signal is a cell-specific reference signal or a CoMP-zone-specific reference signal. A method for transmitting the cell-specific reference signal uses a CoMP set ID or does not apply a frequency shift value, or uses a serving cell ID or a frequency shift value of the serving cell. The cell-specific reference signal is transmitted using a preset resource region. A method for transmitting the CoMP-zone-specific reference signal is configured such that the pattern of the sequence of CoMP reference signals varies in each of the CoMP zones, and the pattern can be set in advance. The reference signal is multiplexed using an orthogonal code and transmitted to plural terminals using the same CoMP zone.

    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.
