Downlink Physical Signals

5G NR primary and secondary synchronization signals (PSS and SSS) and reference signals (DM-RS for PBCH and PDSCH, PT-RS for PDSCH, CSI-RS, and PRS)

Primary and secondary downlink synchronization signals are used by the user equipment (UE) to obtain the cell identity and frame timing. The UE uses the demodulation reference signal (DM-RS) and the channel state information reference signal (CSI-RS) to aid channel estimation and to support measurements. For phase noise compensation, the UE uses the PDSCH phase tracking reference signal (PT-RS). Positioning reference signal (PRS) is used to estimate the position of the UE in the wireless network.
