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 the reference signal is transmitted to a plurality of terminals using the same CoMP zone.

摘要： Disclosed is a method for efficiently transceiving information required for implementing a multi-cell-based CoMP MU-MIMO scheme. For this purpose, a base station which performs CoMP operation generates: (A) a reference signal sequence on the basis of a specific base station; or generates (B) the same reference signal sequence on the basis of a CoMP ID, and transmits the generated sequence to user equipment. To support an MU-MIMO scheme and to perform a joint processing method, the base station must additionally transmit CoMP reference signal sequence information, frequency shift information, etc. to the user equipment in said (A) case, and generates a CoMP reference signal on the basis of a preset CoMP set ID and transmits the generated signal to the user equipment in said (B) case.
