    摘要: A user equipment (UE) receiving a plurality of reference signals in a wireless multiple-input multiple-output (MIMO) communication system includes a transceiver configured for receiving the plurality of reference signals for multiple antennas in a sub-frame, the sub-frame including a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols in a time domain over a plurality of sub-carriers in a frequency domain. A first array is repeated in the frequency domain on a first OFDM symbol of the sub-frame, a second array is repeated in the frequency domain on a second OFDM symbol of the sub-frame and a third array is repeated in the frequency domain on a third OFDM symbol of the sub-frame, and each of the first, second and third arrays consists of six contiguous symbols in the frequency domain.

    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.
