Parameter |
Description |
FPointA |
Reference Point A frequency. |
Fcarrier |
Fcarrier is the centre frequency of a carrier corresponding to its NR-ARFCN value. |
FcarrierLow |
FcarrierLow is the centre frequency of lowest subcarrier of the carrier. |
ΔFcarrierBandwidth |
ΔFcarrierBandwidth is the carrier’s channel bandwidth as provided in carrierBandwidth to the UE (SCS-SpecificCarrier). |
ΔFoffsetToCarrier |
ΔFoffsetToCarrier is the frequency offset between Point A and the lower edge of the carrier. FoffsetToCarrier = offsetToCarrier * PRB size, where PRB size according to the subcarrier spacing of the carrier. offsetToCarrier is signalled to the UE (SCS-SpecificCarrier). |
FSSref |
Centre frequency of SSB. For a cell selectable as PCell the FSSref corresponds to a valid GSCN value according to clause 5.4.3.1 of TS 38.101-1 [7] and TS 38.101-2 [8]. |
ΔFOffset(RBs) |
ΔFOffset(RBs) = 12* Offset(RBs) * subCarrierSpacingCommon, where Offset(RBs) is given in tables 13-1 to 13-10 of TS 38.213 [22]. |
ΔFkSSB |
ΔFKSSB = kSSB * subcarrier spacing of SSB (SCSSSB). |
ΔFOffsetSSB-CORESET0 |
Frequency offset between the lowest subcarrier of the SSB and the lowest subcarrier of CORESET#0. ΔFOffsetSSB-CORESET0 = ΔFOffset(RBs) + ΔFkSSB. |
ΔFOffsetCORESET-0-Carrier |
Frequency offset, FOffsetCORESET#0-Carrier, between the lowest subcarrier of CORESET#0 and the lowest subcarrier of the carrier. |
ΔFOffsetSSB-Carrier |
Frequency offset between the lowest subcarrier of the SSB and the lowest subcarrier of the carrier. |
FCORESET0Low |
Centre frequency of subcarrier 0 of CORESET#0. |
FOffsetToPointA |
Frequency of the lowest subcarrier of the lowest resource block, which has the subcarrier spacing provided by the higher-layer parameter subCarrierSpacingCommon and overlaps with the SS/PBCH block used by the UE for initial cell selection, expressed in units of resource blocks assuming 15 kHz subcarrier spacing for FR1 and 60 kHz subcarrier spacing for FR2 (TS 38.211 [29] clause 4.4.4.2). |
ΔFOffsetToPointA |
Frequency offset between FOffsetToPointA and point A. ΔFOffsetToPointA = offsetToPointA * {15 kHz for FR1; 60 kHz for FR2} (TS 38.211 [29] clause 4.4.4.2). |
