SpletIn this scenario, NR PDSCH is punctured (rate matches) around NR CRS and LTE CRS now visible to the mobile device across the full frequency span. It seems (at least to me) that there is no problem and this scenario would work. To apply this trick, UE need to support following capability (in UE capability information) RF-Parameters ::= SEQUENCE { SpletThe 5G PDSCH configuration consists of two layers, mapping type A, allocated symbols from 3 to 13, a DM-RS in symbol 3, and an additional DM-RS. The figure shows the 5G PDSCH rate-matching around the REs allocated for the LTE CRS and the additional DM-RS allocated in symbol 12, instead of 11, to avoid collisions with the LTE CRS in antenna 1.
