Fields (3)

FieldDescription
locationAndBandwidthBroadcast-r17
LocationAndBandwidthBroadcast-r17 · OPTIONAL Need S
Indicates starting PRB and the number of PRBs of CFR used for MCCH, multicast MCCH and MTCH reception. Value sameAsSib1ConfiguredLocationAndBW means the CFR for broadcast or multicast has the same location and size as the locationAndBandwidth for initial BWP (for (e)RedCap UEs: initialDownlinkBWP-RedCap if it is configured and includes CD-SSB and the entire CORESET#0) configured in SIB1 . Value locationAndBandwidth is used to configure CFR with bandwidth that is larger than and fully contains the bandwidth for the initial DL BWP (for (e)RedCap UEs: initialDownlinkBWP-RedCap if it is configured and includes CD-SSB and the entire CORESET#0) configured in SIB1 and CORESET#0. The value of the field shall be interpreted as defined in TS 38.214 [19] with assumptions as described in TS 38.213 [13]. This field is not included in cfr-ConfigMCCH-MTCH-RedCap if initialDownlinkBWP-RedCap in SIB1 is configured but does not include CD-SSB and the entire CORESET#0. If the field is absent, the CFR for broadcast or multicast has the same location and size as CORESET#0.
pdsch-ConfigMCCH-r17
PDSCH-ConfigBroadcast-r17 · OPTIONAL Need S
Indicates PDSCH parameters used for MCCH or multicast MCCH transmission. If the field is absent, PDSCH parameters used for MCCH or multicast MCCH are the same as those of PDSCH configuration provided in initialDownlinkBWP in SIB1 .
commonControlResourceSetExt-r17
ControlResourceSet · OPTIONAL Cond NotSIB1CommonControlResource
An additional common control resource set which may be configured and used for searchSpaceMCCH / searchSpaceMTCH or UE-specific search space in the BWP where searchSpaceMCCH is configured. It is contained in the bandwidth of the CFR for broadcast and larger than CORESET#0.
