Definition
CFRA-CSIRS-Resource ::= SEQUENCE {

ra-PreambleIndex INTEGER (0..63),
...
}Fields (3)
| Field | Description |
|---|---|
| csi-RS CSI-RS-Index since v15.1.0 | The ID of a CSI-RS resource defined in the measurement object associated with this serving cell. |
| ra-OccasionList SEQUENCE (SIZE(1..maxRA-OccasionsPerCSIRS)) OF INTEGER (0..maxRA-Occasions-1) since v15.1.0 | RA occasions that the UE shall use when performing CF-RA upon selecting the candidate beam identified by this CSI-RS. The network ensures that the RA occasion indexes provided herein are also configured by prach-ConfigurationIndex and msg1-FDM. Per RO type (the first or the second PRACH occasions as specified in TS 38.213 [13], clause 8), each RACH occasion is sequentially numbered, first, in increasing order of frequency resource indexes for frequency multiplexed PRACH occasions; second, in increasing order of time resource indexes for time multiplexed PRACH occasions within a PRACH slot and Third, in increasing order of indexes for PRACH slots. |
| ra-PreambleIndex INTEGER (0..63) | The RA preamble index to use in the RA occasions associated with this CSI-RS. |
