Demodulation reference signal mapping manner, transfer manner, and the communication terminal device and the demodulation reference signal transfer device and the reception manner which use that

摘要

This invention, the demodulation reference signal (DM RS) being mapping manner, transfer manner, and something regarding the communication terminal device, when it transfers DM RS which differs especially odd number vis-a-vis the layer, is something in order to offer DM RS mapping manner and the transfer manner which it tries to maintain the reception reliability of DM RS for each layer uniformly.
