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： The present invention relates to a method for transmitting a reference signal (RS) for measuring a channel in a downlink MIMO (Multi Input Multi Output) system that supports: a first user device supporting N base station transmission antennas out of a total of M base station transmission antennas and a second user device supporting M (M>N) base station transmission antennas. The method comprises the steps of: grouping a certain number of subframes or a resource block (RB) to transmit a common reference signal (CRS) for M transmission antennas from the base station; and transmitting the subframes or the resource block to the second user device. The grouped subframes or the resource block are transmitted to the second user terminal in a specific time period, and in the subframes or the resource block, the common reference signal is mapped to different transmission antenna ports corresponding to a quotient which is obtained by dividing M by a specific number.
