–SI-SchedulingInfo
The IE SI-SchedulingInfo contains information needed for acquisition of SI messages.
SI-SchedulingInfo ::= SEQUENCE {
schedulingInfoList SEQUENCE (SIZE (1..maxSI-Message)) OF SchedulingInfo,
si-WindowLength
ENUMERATED {s5, s10, s20, s40, s80, s160, s320, s640, s1280},

si-RequestConfigSUL
SI-RequestConfig OPTIONAL, -- Cond SUL-MSG-1
systemInformationAreaID
BIT STRING (SIZE (24)) OPTIONAL, -- Need R
...
}
SchedulingInfo: It will have information whether the corresponding SI-message is being broadcasted or not, periodicity of SI-message and a list of SIBs mapped to this SI-message. For each SIB, SIB type, valueTag, areaScope flag are provided. areaScope indicates whether the SIB is area specific or not.
SchedulingInfo ::= SEQUENCE {
si-BroadcastStatus
ENUMERATED {broadcasting, notBroadcasting},
si-Periodicity
ENUMERATED {rf8, rf16, rf32, rf64, rf128, rf256, rf512},
sib-MappingInfo SIB-Mapping
}
SIB-Mapping ::= SEQUENCE (SIZE (1..maxSIB)) OF SIB-TypeInfo
SIB-TypeInfo ::= SEQUENCE {
type ENUMERATED {sibType2, sibType3, sibType4, sibType5, sibType6, sibType7, sibType8, sibType9,
sibType10-v1610, sibType11-v1610, sibType12-v1610, sibType13-v1610, sibType14-v1610,
spare3, spare2, spare1,... },
valueTag INTEGER (0..31) OPTIONAL, -- Cond SIB-TYPE
areaScope
ENUMERATED {true} OPTIONAL -- Need S
}
si-WindowLength: The length of the SI scheduling window. Value s5 corresponds to 5 slots, value s10 corresponds to 10 slots and so on. The network always configures si-WindowLength to be shorter than or equal to the si-Periodicity.
si-RequestConfig: It has all the important configuration for MSG1 resources.
si-RequestConfigSUL: It is the corresponding configuration on SUL.
systemInformationAreaID: It indicates the system information area that the cell belongs to, if any. The systemInformationAreaID is unique within a PLMN.
SI-RequestConfig:
The IE SI-RequestConfig contains configuration for Msg1 based SI request. If the field is absent the UE uses Msg3 to request SI-messages.

ra-ssb-OccasionMaskIndex INTEGER (0..15) OPTIONAL -- Need R
}
rach-OccasionsSI: Configuration of dedicated RACH Occassions for SI. If the field is absent, the UE uses the corresponding parameters configured in rach-ConfigCommon of the initial uplink BWP.
si-RequestPeriod: Periodicity of the SI-Request configuration in number of association periods.
si-RequestResources: If there is only one entry in the list, the configuration is used for all SI messages for which si-BroadcastStatus is set to notBroadcasting. Otherwise the 1st entry in the list corresponds to the first SI message in schedulingInfoList for which si-BroadcastStatus is set to notBroadcasting, 2nd entry in the list corresponds to the second SI message in schedulingInfoList for which si-BroadcastStatus is set to notBroadcasting and so on. Change of si-RequestResources should not result in system information change notification.
RACH-ConfigGeneric *Important*
The IE RACH-ConfigGeneric is used to specify the random-access parameters both for regular random access as well as for beam failure recovery.
RACH-ConfigGeneric ::= SEQUENCE {

}
prach-ConfigurationIndex: PRACH configuration index. For prach-ConfigurationIndex configured under beamFailureRecovery-Config, the prach-ConfigurationIndex can only correspond to the short preamble format.
msg1-FDM: The number of PRACH transmission occasions FDMed in one time instance.
