Uplink Physical Signals

5G NR demodulation and phase tracking reference signals (DM-RS and PT-RS) for PUSCH and sounding reference signal (SRS)

The base station uses the DM-RS and the SRS to aid channel estimation and to support measurements. For phase noise compensation, the base station uses the PUSCH PT-RS.
