METHOD FOR MAPPING AND TRANSMITTING DEMODULATION REFERENCE SIGNAL (DM-RS), COMMUNICATION TERMINAL DEVICE USING SAME, APPARATUS FOR TRANSMITTING DM-RS, AND METHOD FOR RECEIVING DM-RS

摘要

The present invention relates to a method for mapping and transmitting demodulation reference signal (DM-RS) and a communication terminal device, and more particularly to a method for mapping and transmitting DM-RS which uniformly maintains reception reliability of DM-RS for each layer in a process for transmitting different DM-RSs for odd-numbered layers.
