One Measurement id consists of one measurement object Id and one reporting config id. Each measurement object is identified with a id i.e. measObjectId.

measObjectId MeasObjectId,
measObject CHOICE {
measObjectEUTRA MeasObjectEUTRA,
measObjectUTRA MeasObjectUTRA,
measObjectGERAN MeasObjectGERAN,
measObjectCDMA2000 MeasObjectCDMA2000,
...
}
}

ReportConfigToAddMod ::= SEQUENCE {
reportConfigId ReportConfigId,
reportConfig CHOICE {
reportConfigEUTRA ReportConfigEUTRA,
reportConfigInterRAT ReportConfigInterRAT
}
