DSS Part-3
Home LTE NB-IoT 5G(NR-NSA) DSS: Other NR UE features that are considered important for an efficient operation of spectrum sharing are: PDCCH in symbol 2 Rate matching pattern to map around LTE PSS/SSS and PBCH TRS in symbol 6 and 10 Flexible CSI-RS placement Alternative PDSCH DM-RS pattern when LTE CRS rate matching is configured 7.5 kHz UL shift DSS will help a mobile operator to flexibly allocate existing spectrum across low-, mid- and high- frequency bands, by dynamically switching between 4G LTE and 5G NR coverage based on traffic demand.Mobile operators can hold DSS to deliver the best possible performance and coverage for a mix of 4G and 5G devices. How LTE overhead can be avoided? 5G capacity is impacted by LTE Cell Reference Signals (CRSs),PDCCH, PSS, SSS, PBCH and MBSFN subframes overheads as well as NR PDSCH DMRS and NR corset.There is less impact from the 5G control channels on LTE as 5G does not use an
