Fields (8)
| Field | Description |
|---|---|
| redCap-r17 ENUMERATED {true} · OPTIONAL Need R since v17.1.0 | If present, this field indicates that RedCap is part of this feature combination. |
| smallData-r17 ENUMERATED {true} · OPTIONAL Need R since v17.1.0 | If present, this field indicates that Small Data is part of this feature combination. |
| nsag-r17 NSAG-List-r17 · OPTIONAL Need R since v17.1.0 | If present, this field indicates NSAG(s) that are part of this feature combination. |
| msg3-Repetitions-r17 ENUMERATED {true} · OPTIONAL Need R since v17.1.0 | If present, this field indicates that signalling of msg3 repetition is part of this feature combination. This field is not configured in a set of preambles that is configured with 2-step random-access type. |
| msg1-Repetitions-r18 ENUMERATED {true} · OPTIONAL Need R since v18.0.0 | If present, this field indicates that signalling of msg1 repetition is part of this feature combination. This field is not configured in a set of preambles that is configured with 2-step random-access type. |
| eRedCap-r18 ENUMERATED {true} · OPTIONAL Need R since v18.0.0 | If present, this field indicates that eRedCap is part of this feature combination. The fields redCap and eRedCap shall not be both set to true . If the UE is an eRedCap UE and there is no set of configured RA resources with eRedCap set to true among all sets of configured RA resources, the UE considers redCap to be applicable for random access procedure. This field is not configured in a set of preambles that is configured with 2-step random-access type. |
| spare2 ENUMERATED {true} · OPTIONAL Need R since v17.1.0 | |
| spare1 ENUMERATED {true} · OPTIONAL Need R since v17.1.0 |
