Control resource set configuration enhancement for off-raster synchronization signal blocks in an integrated access and backhaul

An integrated access and backhaul (IAB) node, comprising:

• a wireless communication radio front end module (RFEM) including one or more antennas;
• and
• processing circuitry coupled to the wireless communication RFEM, wherein the processing circuitry is configured to:
• receive a setting to transmit an in-raster synchronization signal block (SSB) and an off-raster SSB;
• determine 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, modify a bit pattern of a configuration table corresponding to the shared CORESET to add a configuration entry to support the off-raster SSB;
• and
• broadcast the in-raster SSB and the off-raster SSB via the one or more antennas of the RFEM, wherein the in-raster SSB and the off-raster SSB include the modified bit pattern corresponding to the shared CORESET.

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 zero (CORESET0) configuration;
• if the determining indicates that the same CORESET0 is shared, modifying a bit pattern of a configuration table corresponding to the shared CORESET0 configuration 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 CORESET0 configuration.
