1. A method, comprising:
receiving a setting for an integrated access and backhaul (IAB) node to transmit an in-raster synchronization signal block (SSB) and an off-raster SSB;
determining whether the setting indicates that the in-raster SSB and the off-raster SSB share the same control resource set (CORESET);
if the determining indicates that the same CORESET is shared, modifying a bit pattern of a configuration table corresponding to the shared CORESET to add a configuration entry to support the off-raster SSB; and
broadcasting the in-raster SSB and the off-raster SSB, wherein the in-raster SSB and the off-raster SSB include the modified bit pattern corresponding to the shared CORESET.
