| Field | Description |
|---|---|
| multicastMCCH-Config-r18 MCCH-Config-r17 · OPTIONAL Need S | Indicates MCCH configuration for MBS multicast reception in RRC_INACTIVE. This field is always included if it is provided via broadcast signalling in SIB24 . |
| cfr-ConfigMCCH-MTCH-r18 CFR-ConfigMCCH-MTCH-r17 · OPTIONAL Need S | Common frequency resource used for multicast MCCH and/or multicast MTCH reception. If the field is absent, the CFR for multicast has the same location and size as CORESET#0 and PDSCH configuration of multicast MCCH, if present, is the same as PDSCH configuration provided in initialDownlinkBWP in SIB1 . |
| lateNonCriticalExtension OCTET STRING · OPTIONAL |
