The statement "The start symbol of a front-loaded DMRS of a type B PDSCH is always the first symbol of PDSCH" is incorrect. In 5G NR, the start symbol of a front-loaded DMRS of a type B PDSCH can be configured as the first symbol of PDSCH or as the second symbol of PDSCH.You can refer to the Huawei official documentation for HCIP-5G-RAN V2.0 certification and the 3GPP 5G NR standard (38.211, 38.212, 38.213) for more information on PDSCH DMRS, including the configurations of the front-loaded DMRS, the DMRS symbols and the optional and mandatory nature of it.Here are some official references:Huawei HCIP-5G-RAN V2.0 certification page: https://e.huawei.com/en/certifications/hcip-5g-ranv2-03GPP5G NR standard: https://www.3gpp.org/specifications/5g-nr-specifications

The statement A is incorrect. The larger the subcarrier spacing [1], the shorter the symbol duration on each subcarrier, not the larger number of symbols. Statement B is also incorrect. The larger the subcarrier spacing [1], the larger the CP length and the more suitable it becomes for wide coverage.Statement C is correct. The smaller the subcarrier spacing, the lower the power spectral density.Statement D is incorrect. The larger the subcarrier spacing [1], the shorter the slot length.https://asp-eurasipjournals.springeropen.com/articles/10.1186/s13634-020-00696-11.

The UE inactivity timer on the NR side expiring and the air interface link on the NR side being abnormal, and a UE reporting SCG Failure Info to the eNodeB, can both trigger the MeNB to release the SgNB. Other actions, such as an inter-SgNB cell change or the MeNB detecting an abnormal X2 link, may also lead to SgNB release, but are not the trigger for it.https://www.sciencedirect.com/topics/engineering/extended-cyclic-prefixExtended Cyclic Prefix - an overview | ScienceDirect Topicshttps://www.sciencedirect.com/topics/engineering/extended-cyclic-prefixhttp://www.techplayon.com/5g-nr-numerology-subcarrier-spcaing-scs/5G NR Numerology - Subcarrier Spcaing (SCS)  Techplayonhttp://www.techplayon.com/5g-nr-numerology-subcarrier-spcaing-scs/
