Definition

The IE PDSCH-ConfigBroadcast is used to configure parameters for acquiring the PDSCH for MCCH, multicast MCCH and MTCH.

Fields (6)

FieldDescription
pdschConfigList-r17
SEQUENCE (SIZE (1..maxNrofPDSCH-ConfigPTM-r17) ) OF PDSCH-ConfigPTM-r17
List of PDSCH parameters which can be configured per G-RNTI. Only one entry is allowed to be configured if included in SIB20 or SIB24 .
pdsch-TimeDomainAllocationList-r17
PDSCH-TimeDomainResourceAllocationList-r16 · OPTIONAL Need R
List of time-domain configurations for timing of DL assignment to DL data. The field pdsch-TimeDomainAllocationList applies to DCI format 4_0 (see table 5.1.2.1.1-1 in TS 38.214 [19]). When the field is absent, the UE follows PDSCH time domain resource allocation determination rule as specified in TS 38.214 [19], clause 5.1.2.1.1.
rateMatchPatternToAddModList-r17
SEQUENCE (SIZE (1..maxNrofRateMatchPatterns)) OF RateMatchPattern · OPTIONAL Need R
Resources patterns which the UE should rate match PDSCH around. The UE rate matches around the union of all resources indicated in the rate match patterns (see TS 38.214 [19], clause 5.1.4.1).
lte-CRS-ToMatchAround-r17
RateMatchPatternLTE-CRS · OPTIONAL Need R
since v17.1.0
Parameters to determine an LTE CRS pattern that the UE shall rate match around.
mcs-Table-r17
ENUMERATED {qam256, qam64LowSE} · OPTIONAL Need S
Indicates which MCS table the UE shall use for PDSCH. If the field is absent the UE applies the value 64QAM. The field mcs-Table applies to DCI format 4_0 with CRC scrambled by MCCH-RNTI/G-RNTI for MBS broadcast or by Multicast MCCH-RNTI for MBS multicast in RRC_INACTIVE, and applies to DCI format 4_1 with CRC scrambled by G-RNTI for MBS multicast in RRC_INACTIVE (see TS 38.214 [19], clause 5.1.3.1).
xOverhead-r17
ENUMERATED {xOh6, xOh12, xOh18} · OPTIONAL Need S
Accounts for an overhead from CSI-RS, CORESET, etc. If the field is absent, the UE applies value xOh0 (see TS 38.214 [19], clause 5.1.3.2).
