Abstract: Subcarrier spacing (SCS) for data may be adapted or dynamically configured based on the occurrence or presence of a synchronization signal block (SSB) transmission. For example, during a SSB transmission, the SCS of data may be automatically switched from some default data SCS to a second SCS (e.g., the SCS of the SSB) to allow for frequency division multiplexing (FDM) of data and SSB where the data and SSB use the same numerology. As such, communicating devices (e.g., a base station and a user equipment (UE)) may identify some location or configuration for a SSB, and may determine a second subcarrier spacing (e.g., a subcarrier spacing associated with the SSB) such that the SCS of data may be adapted to the second subcarrier spacing during the FDM of the SSB and the data. The SSB and data may thus be contemporaneously transmitted or received using the second SCS.
