First of all, The PDSCH scheduled only using DCI format 1-1 is determined by the DMRS sequence initialization field in DCI format 1-1, otherwise the value is 0.. One method is to use RateMatchPatternLTE-CRS in Rrc and this is mainly used when NR radio frequency is overlapping with LTE spectrum as you see in DSS. Main purpose of this configuration is to avoid scheduling PDSCH in LTE CRS RE (Cell specific Reference Signal Resource Element). Refer to this note for the details. Jul 24, 2017 · DMRS is used to estimate the radio channel for demodulation. DMRS is UE-specific, can be beamformed, confined in a scheduled resource, and transmitted only when necessary, both in DL and UL. To support multiple-layer MIMO transmission, multiple orthogonal DMRS ports can be scheduled, one for each layer.

In LTE (at least in TM1, 2, 3, 4), we don't need this kind of special DMRS for PDSCH because we can use CRS (Cell Specific Reference Signal) for PDSCH decoding.By using different SCS in 5G NR, different slot durations and TTIs are configurable.For example, 15kHz SCS with 14 symbols spanning the entire subframe corresponds to LTE's configuration. At 240kHz SCS (for control only), 14 symbols are squeezed into a 62.5µs slot. In Release 16, 120kHz is the maximum SCS allowed for data. Hence, the lowest achievable slot duration is 125µs.DMRS Length - Sets the DMRS duration. The PUSCH DMRS duration can be 1 symbol or two symbols and is limited by the DMRS Max Length.
