1.SSB的subcarrierSpacing
SA的场景中：
NSA（ENDC）的场景中：
RRC setup(msg4)=>CellGroupConfig=>Spcellconfig=>ReconfigurationWithSync=>ServingCellConfigCommon
2.Subcarrier spacing for SIB1, Msg.2/4 for initial access, paging and broadcast SI-messages.
If the UE acquires this MIB on an FR1 carrier frequency, the value scs15or60 corresponds to 15 kHz and the value scs30or120 corresponds to 30 kHz. If the UE acquires this MIB on an FR2 carrier frequency, the value scs15or60 corresponds to 60 kHz and the value scs30or120 corresponds to 120 kHz.
PS:NSA中的band信息应该也是在msg4信息中配置的

Subcarrier spacing to be used in this BWP for all channels and reference signals unless explicitly configured elsewhere. Corresponds to subcarrier spacing according to TS 38.211 [16], table 4.2-1. The value kHz15 corresponds to µ=0, value kHz30 corresponds to µ=1, and so on. Only the values 15 kHz, 30 kHz, or 60 kHz (FR1), and 60 kHz or 120 kHz (FR2) are applicable. For the initial DL BWP this field has the same value as the field subCarrierSpacingCommon in MIB of the same serving cell.
