Definition

The IE SCellActivationRS-Config is used to configure a Reference Signal for fast activation of the SCell where the IE is included (see TS 38.214 [19], clause 5.2.1.5.3. Usage of an SCellActivationRS-Config is indicated by including its scellActivationRS-Id in the Enhanced SCell activation MAC CE (see TS 38.321 [3] clause 6.1.3.55).

FieldDescription
scellActivationRS-Id-r17
SCellActivationRS-ConfigId-r17
resourceSet-r17
NZP-CSI-RS-ResourceSetId
nzp-CSI-ResourceSetId of the NZP-CSI-RS-ResourceSet of this serving cell used as resource configuration for one or two bursts for SCell activation. This NZP-CSI-RS-ResourceSet consists of four NZP CSI-RS resources in two consecutive slots with two NZP CSI-RS resources in each slot (see TS 38.214 [19], clause 5.1.6.1.1.1). The CSI-RS associated with this NZP-CSI-RS-ResourceSet are located in the BWP addressed by firstActiveDownlinkBWP-Id.
gapBetweenBursts-r17
INTEGER (2..31) · OPTIONAL Need R
When this field is present, there are two bursts and it indicates the gap between the two bursts in number of slots. When this field is absent, there is a single burst.
qcl-Info-r17
TCI-StateId
Reference to TCI-State for providing the QCL source and QCL type for each NZP-CSI-RS-Resource listed in nzp-CSI-RS-Resources of the NZP-CSI-RS-ResourceSet indicated by resourceSet (see TS 38.214 [19], clause 5.1.6.1.1.1). TCI-StateId refers to the TCI-State which has this value for tci-StateId and is defined in tci-StatesToAddModList or dl-OrJointTCI-StateList in the PDSCH-Config included in the BWP-Downlink of this serving cell indicated by firstActiveDownlinkBWP-Id in the ServingCellConfig in which this IE is included.
