Title: SYSTEM AND METHOD FOR DEMODULATION REFERENCE SIGNAL OVERHEAD REDUCTION
Abstract:
An embodiment method defines a demodulation reference signal (DMRS) pattern for transmitting DMRSs for rank 3 or rank 4 transmissions. The DMRS pattern specifies 12 REs in total per physical resource block (PRB) for carrying DMRSs on three or four antenna ports in antenna ports 7-14 for rank 3 or rank 4 transmissions. DMRS settings for transmitting DMRS according to the DMRS pattern may be specified using a downlink control information table.
