Fields (8)

FieldDescription
frequencyBandList
MultiFrequencyBandListNR · OPTIONAL Cond FDD-OrSUL-OrEarlyUL-Sync
since v15.1.0
List containing only one frequency band to which this carrier(s) belongs. Multiple values are not supported.
absoluteFrequencyPointA
ARFCN-ValueNR · OPTIONAL Cond FDD-OrSUL-OrEarlyUL-Sync
since v15.1.0
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
since v15.2.0
A set of carriers for different subcarrier spacings (numerologies). Defined in relation to Point A. The network configures a scs-SpecificCarrier at least for each numerology (SCS) that is used e.g. in a BWP (see TS 38.211 [16], clause 5.3).
additionalSpectrumEmission
AdditionalSpectrumEmission · OPTIONAL Need S
The additional spectrum emission requirements to be applied by the UE on this uplink. If both additionalSpectrumEmission (without suffix) and additionalSpectrumEmission-v1760 are absent, the UE uses value 0 for the additionalSpectrumEmission (see TS 38.101-1 [15], tables 6.2.3.1-1A, 6.2A.3.1.1-2 and 6.2A.3.1.2-2, TS 38.101-2 [39], tables 6.2.3.1-2 and 6.2A.3.1-2, and TS 38.101-5 [75], table 6.2.3.1-1A). Network configures the same value in additionalSpectrumEmission for all uplink carrier(s) of the same band with UL configured and if signalled, the same vaue in additionalSpectrumEmission-v1760 for all uplink carrier(s) of the same band with UL configured, except for additionalSpectrumEmission value corresponding to NS_55/NS_57. If NS_55/NS_57 (see TS 38.101-1 [15], table 6.2.3.1-1) is applicable for at least one uplink carrier, the network may configure either NS_55/NS_57 or NS_01 for these uplink carriers, and NS_01 for the remaining uplink carrier(s) of band n77. The additionalSpectrumEmission is applicable for all uplink carriers of the same band with UL configured.
p-Max
P-Max · OPTIONAL Need S
Maximum transmit power allowed in this serving cell. The maximum transmit power that the UE may use on this serving cell may be additionally limited by p-NR-FR1 (configured for the cell group) and by p-UE-FR1 (configured total for all serving cells operating on FR1). If absent, the UE applies the maximum power according to TS 38.101-1 [15] in case of an FR1 cell, TS 38.101-2 [39] in case of an FR2 cell or TS 38.101-5 [75] in case of an NTN cell. In this release of the specification, if p-Max is present on a carrier frequency in FR2, the UE shall ignore the field and applies the maximum power according to TS 38.101-2 [39] for FR2-1/2 or according to TS 38.101-5 [75] for FR2-NTN. Value in dBm. This field is ignored by IAB-MT and NCR-MT. The IAB-MT applies output power and emissions requirements, as specified in TS 38.174 [63]. The NCR-MT applies output power and emission requirements as specified in TS 38.106 [79].
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.
additionalSpectrumEmission-v1760
AdditionalSpectrumEmission-v1760 · OPTIONAL Need S
since v17.6.0
The additional spectrum emission requirements to be applied by the UE on this uplink. If both additionalSpectrumEmission (without suffix) and additionalSpectrumEmission-v1760 are absent, the UE uses value 0 for the additionalSpectrumEmission (see TS 38.101-1 [15], tables 6.2.3.1-1A, 6.2A.3.1.1-2 and 6.2A.3.1.2-2, TS 38.101-2 [39], tables 6.2.3.1-2 and 6.2A.3.1-2, and TS 38.101-5 [75], table 6.2.3.1-1A). Network configures the same value in additionalSpectrumEmission for all uplink carrier(s) of the same band with UL configured and if signalled, the same vaue in additionalSpectrumEmission-v1760 for all uplink carrier(s) of the same band with UL configured, except for additionalSpectrumEmission value corresponding to NS_55/NS_57. If NS_55/NS_57 (see TS 38.101-1 [15], table 6.2.3.1-1) is applicable for at least one uplink carrier, the network may configure either NS_55/NS_57 or NS_01 for these uplink carriers, and NS_01 for the remaining uplink carrier(s) of band n77. The additionalSpectrumEmission is applicable for all uplink carriers of the same band with UL configured.
additionalSpectrumEmissionAerial-r18
AdditionalSpectrumEmission-r18 · OPTIONAL Need S
since v18.0.0
The additional spectrum emission requirements to be applied by the aerial UE on this uplink (see TS 38.101-1 [15], clause 6.2K). If the field is absent, the aerial UE uses value indicated by the field additionalSpectrumEmission/ additionalSpectrumEmission-v1760 .
