METHOD FOR TRANSMITTING SOUNDING REFERENCE SIGNAL SEQUENCE USING PLURAL ANTENNAS

摘要

Disclosed is a method for transmitting a sounding reference signal from a mobile terminal that includes plural antennas. Different plural sounding reference signal sequences that have mutual orthogonality are mapped to each antenna, and then transmitted. Or, the same sounding reference signal sequence is mapped to the plural antennas after precoding or cyclic delay diversity processing, and then transmitted.
