Document Type and Number:
WIPO Patent Application WO/2013/183581
Kind Code:
A1
Abstract:
In the present invention, a reference signal generator (105) generates a reference signal and inputs it to resource mapping units (106-1 to 106-T). There are a number of types of reference signals, according to the purpose thereof, but here only a user-specific reference signal for demodulation (DM-RS) is described. The resource mapping units (106-1 to 106-T) map, to resources, input from a pre-coding unit (104) and the DM-RS so as to be perpendicular between transmission antennas and between transmission points.
