Fields (7)
| Field | Description |
|---|---|
| tci-UL-StateId-r18 TCI-UL-StateId-r17 | |
| referenceSignal-r18 CHOICE { | Reference signal with which spatial relation information is provided. The field csi-RS-Index refers to one of the NZP-CSI-RS-Resource configured within LTM-TCI-Info , if present. Otherwise, the field csi-RS-Index refers to one of the NZP-CSI-RS-Resource configured outside LTM-TCI-Info (within LTM-Candidate ). |
| ssb-Index SSB-Index | The index of a SSB/PBCH block as indicated in ltm-SSB-Config of the LTM candidate that includes this CandidateTCI-UL-State . |
| csi-RS-Index NZP-CSI-RS-ResourceId | Indicates an NZP-CSI-RS-Resource of the LTM candidate that includes this CandidateTCI-UL-State . |
| pathlossReferenceRS-Id-r18 PathlossReferenceRS-Id-r17 · OPTIONAL Need R | Indicates a PathlossReferenceRS of the LTM candidate that includes this CandidateTCI-UL-State and it refers to one of the PathlossReferenceRS configured within LTM-TCI-Info . In this version of the specification, only SSB can be included as reference signal when PathlossReferenceRS is included within a CandidateTCI-UL-State IE. |
| tag-Id-ptr-r18 ENUMERATED {n0,n1} · OPTIONAL Cond 2TA since v18.2.0 | |
| ul-PowerControl-r18 Uplink-powerControlId-r17 · OPTIONAL Cond separateTCI since v18.3.0 | Indicates the UL power control parameters for PUSCH, PUCCH, and SRS of the candidate that includes this CandidateTCI-UL-State . This field refers to an element in the list configured using uplink-PowerControlToAddModList in the SpCellConfig of the ltm-CandidateConfig in the LTM-Candidate where the ltm-TCI-Info is configured. |
