REFERENCE SIGNAL TRANSMITTING METHOD AND DEVICE IN MULTIPLE ANTENNA SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a method and device for transmitting a reference signal in a multiple antenna system.SOLUTION: A reference signal transmitting method in a multiple antenna system includes the stages of: selecting at least one OFDM symbol at a sub-frame including multiple OFDM symbols; allocating a CQI RS able to measure a channel state for each of the multiple antennas to the selected at least one OFDM symbol; and transmitting the CQI RS. The CQI RS is characterized in that it is allocated to an OFDM symbol that does not overlap with an OFDM symbol allocated a shared reference signal commonly transmitted to all terminals in a cell or an exclusive reference signal transmitted to a particular terminal in the cell.
