TCI-ActivatedConfig (TCI-ActivatedConfig-r17)
TCI-ActivatedConfig-r17 is an RRC information element of 3GPP TS 38.331 (38331), the 5G NR Radio Resource Control (RRC) protocol.
Definition
The IE TCI-ActivatedConfig is used to provide activated TCI states for PDSCH and/or PDCCH of the PSCell or of an SCell.
TCI-ActivatedConfig-r17 ::= SEQUENCE {
pdcch-TCI-r17 SEQUENCE (SIZE (1..5)) OF TCI-StateId,
pdsch-TCI-r17 BIT STRING (SIZE (1..maxNrofTCI-States))
}Fields (2)
| Field | Description |
|---|---|
| pdcch-TCI-r17 SEQUENCE (SIZE (1..5)) OF TCI-StateId | Indicates the TCI state for PDCCH for each configured CORESET of the DL BWP to be activated at SCell activation, to be activated for the PSCell at SCG activation and/or to be used for BFD, RLM and measurements while the SCG is deactivated. The list includes exactly as many entries as CORESETs configured in this BWP, ordered by increasing values of ControlResourceSet-Id , i.e. the first entry indicates the TCI state for the configured CORESET with the lowest ControlResourceset-Id value , the second value indicates the TCI states for the configured CORESET with the second lowest ControlResourceset-Id value, and so on. |
| pdsch-TCI-r17 BIT STRING (SIZE (1..maxNrofTCI-States)) | Indicates TCI states for PDSCH reception at SCell addition/activation or of the PSCell at SCG activation. This field indicates activated TCI state(s) for this BWP ordered by increasing values of TCI-StateId , i.e. the first bit indicates the activation state of the TCI state with the lowest TCI-StateId value, the second value indicates the activation status of the TCI state with the second lowest TCI-State-Id value, and so on. A bit set to 0 indicates that the corresponding TCI state is deactivated, a bit set to 1 indicates that the TCI state is activated. |
