Six types of downlink reference signals are defined:

– Cell-specific Reference Signal (CRS)

– MBSFN reference signal

– UE-specific Reference Signal (DM-RS) associated with PDSCH

– DeModulation Reference Signal (DM-RS) associated with EPDCCH or MPDCCH

– Positioning Reference Signal (PRS)

– CSI Reference Signal (CSI-RS)

There is one reference signal transmitted per downlink antenna port.
