    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.
