METHOD FOR TRANSMITTING REFERENCE SIGNAL IN MULTIPLE ANTENNA SYSTEM

摘要

A method for transmitting a reference signal in a multiple antenna system comprises the steps of: coupling a first reference signal matched to at least one antenna included in a first antenna group and a second reference signal matched to at least one antenna included in a second antenna group, and transmitting the coupled signals in one stream; and transmitting a third reference signal for separating the first reference signal and the second reference signal from the stream. The present invention reduces overheads caused by the reference signals matched to each of the antennas, and adaptively transmits reference signals in accordance with the performance of terminal equipment in the multiple antenna system.
