SpletDM-RS and PT-RS are the reference signals associated with PUSCH. DM-RS is used for channel estimation as part of coherent demodulation of PUSCH. To compensate for the common phase error (CPE), 3GPP 5G NR introduced PT-RS. Phase noise produced in local oscillators introduces a significant degradation at mmWave frequencies.

SpletThen it is mapped to every L symbol, based on time density 1/L. PTRS is not transmitted in OFDM symbols that contain a CORESET or a PDSCH DMRS. PTRS mapping restarts at each DMRS symbol, and is then mapped relative to this symbol. In two adjacent DMRS symbols, mapping restarts using the second DMRS symbol as the reference.
