Fields (15)
| Field | Description |
|---|---|
| prach-ConfigurationIndex-r19 INTEGER (0..255) | |
| msg1-FDM-r19 ENUMERATED {one, two, four, eight} | The number of PRACH transmission occasions FDMed in one time instance. (see TS 38.211 [16], clause 6.3.3.2). The UE is not expected to be configured such that the total number of valid PRACH transmission occasions associated with RA-AdaptConfig and other FDMed PRACH transmission occasions of the associated RACH-ConfigCommon in the same time instance exceeds 8. |
| msg1-FrequencyStart-r19 INTEGER (0..maxNrofPhysicalResourceBlocks-1) | |
| prach-SubsetMaskIndexAdaptation-r19 ENUMERATED {zero, one, two, three} · OPTIONAL Need R | Indicates the PRACH mask index for determining association periods for valid PRACH transmission occasions associated with RA-AdaptConfig . Value zero corresponds to mask index 0 and so on (See TS 38.213 [13], subclause 8.1). |
| ssb-PerRACH-OccasionAndCB-PreamblesPerSSB-r19 CHOICE { · OPTIONAL Need R | |

| validityDurationForRACH-Adaptation-r19 ENUMERATED {n2, n4, n8, n16} | Indicates the validity time duration for availability indication of additional PRACH resources indicated by DCI 1_0 with P-RNTI, time unit is one SI modification period (see TS 38.213 [13], subclause 8.1). |
| valueKforAssociationPatternPeriodsForPRACH-SubsetMask-r19 ENUMERATED {n2, n4, n8, n16} · OPTIONAL Need S | The value of Kmask used for mapping of mask index to association periods per Kmask association pattern periods (See TS 38.213 [13], subclause 8.1). Absence of this field indicates the value 1 . |
