    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： The present invention relates to a method for transmitting a pilot signal in a downlink MIMO (Multi Input Multi Output) system that supports a first UE (User Equipment) supporting N number of transmission antennae out of a total of M transmission antennae and supports a second UE supporting said M (M>N) number of transmission antennae. Said method comprises a step wherein a pilot symbol is placed as an image in the resource block (RB) region on a subframe that enables the transmission of a user-specific pilot symbol to said second UE in a base station; and a step wherein the subframe whereon said pilot symbol has been placed as an image is transmitted, wherein said RB region includes a first region and a second region, and the first region and the second region each include a certain number of continuous OFDM symbols on a respective time axis, and on said first region is placed as an image a cell-specific pilot symbol with respect to the transmission antenna ports 0 to N−1 that can recognize both said first UE and said second UE, and on said second region is placed as an image a user-specific pilot symbol with respect to the transmission antenna ports 0 to M that can recognize said UE only.

    摘要： Disclosed is a method for transmitting a CoMP reference signal for accurate channel estimation. The CoMP reference signal to be transmitted to a terminal which performs a CoMP operation in a multi-cell environment is a cell-specific reference signal or a CoMP-zone-specific reference signal. A method for transmitting the cell-specific reference signal uses an ID of a CoMP set constituted by cells that perform a CoMP operation, or does not apply a frequency shift value while using the ID of a relevant cell, or uses an ID of a serving cell or a frequency shift value of the serving cell. The cell-specific reference signal is transmitted using a preset specific 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. In addition, the reference signal is multiplexed and transmitted using an orthogonal code resource in the event that reference signal is transmitted to a plurality of 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.
