WebQuestion No. 1 Which of the following statements about PDSCH DMR5 is incorrect? A The start symbol of a front-loaded DMRS of a type B PDSCH is always the first symbol of PDSCH. B The front-loaded DMRS is mandatory, and the additional DMRS is optional. C The overhead of type 1 DMRS is less than that of type 2 DMRS. WebSep 26, 2024 · DMRS is used by the receiver (e.g., UE 101or RAN node 111) to estimate the radio channel for demodulation of a corresponding physical channel. In Rel-15 NR, DM-RS is generated using a length 31 Gold Sequence. There are two different DM-RS configurations namely, configuration Type 1 and Type 2.
http://www.dmitryshulgin.com/mlrs/ DM-RS is used to estimate the radio channel. The signal is present only in the RBs allocated for the PDSCH.
