Definition

The IE FrequencyInfoUL-SIB provides basic parameters of an uplink carrier and transmission thereon.

Fields (6)

Field	Description
frequencyBandList MultiFrequencyBandListNR-SIB · OPTIONAL Cond FDD-OrSUL	Provides the frequency band indicator and a list of additionalPmax and additionalSpectrumEmission values as defined in TS 38.101-1 [15], table 6.2.3.1-1, TS 38.101-2 [39], table 6.2.3.1-2, and TS 38.101-5 [75], table 6.2.3.1-1. The UE shall apply the first listed band which it supports in the frequencyBandList field. If frequencyBandList-v1760 is present, it shall contain the same number of entries, listed in the same order as in frequencyBandList (without suffix).
absoluteFrequencyPointA ARFCN-ValueNR · OPTIONAL Cond FDD-OrSUL	Absolute frequency of the reference resource block (Common RB 0). Its lowest subcarrier is also known as Point A (see TS 38.211 [16], clause 4.4.4.2). Note that the lower edge of the actual carrier is not defined by this field but rather in the scs-SpecificCarrierList .
scs-SpecificCarrierList SEQUENCE (SIZE (1..maxSCSs)) OF SCS-SpecificCarrier	A set of carriers for different subcarrier spacings (numerologies). Defined in relation to Point A (see TS 38.211 [16], clause 5.3). The network configures this for all SCSs that are used in UL BWPs configured in this serving cell.
p-Max P-Max · OPTIONAL Need S
frequencyShift7p5khz ENUMERATED {true} · OPTIONAL Cond FDD-TDD-OrSUL-Optional	Enable the NR UL transmission with a 7.5 kHz shift to the LTE raster. If the field is absent, the frequency shift is disabled.
frequencyBandListAerial-r18 MultiFrequencyBandListNR-Aerial-SIB-r18 · OPTIONAL Need S since v18.0.0	Provides the frequency band indicator and a list of additionalPmax and additionalSpectrumEmission values for aerial UE as defined in TS 38.101-1 [15], clause 6.2K. If the field is present, the aerial UE shall apply the first listed band which it supports in the frequencyBandListAerial field. If the field is absent, frequencyBandList applies.
