The time duration spanned by one DL-PRS Resource Set containing repeated DL-PRS Resources should not exceed the periodicity configured by periodicityAndOffset.

If absent, UE assumes the trackingAreaCode of the serving cell.

This field provides satellite ephemeris either in format of position and velocity state vector or in format of orbital parameters. This field is excluded when determining changes in system information, i.e. changes to ephemerisInfo should neither result in system information change notifications nor in a modification of valueTag in SIB1.

Indicate the epoch time for the NTN assistance information. When explicitly provided through SIB, or through dedicated signaling, the EpochTime is the starting time of a DL sub-frame, indicated by a SFN and a sub-frame number signaled together with the assistance information. For serving cell, the field sfn indicates the current SFN or the next upcoming SFN after the frame where the message indicating the epochTime is received. For neighbour cell, the sfn indicates the SFN nearest to the frame where the message indicating the epochTime is received. The reference point for epoch time of the serving or neighbour NTN payload ephemeris and Common TA parameters is the uplink time synchronization reference point. If this field is absent, the epoch time is the end of SI window where this SIB19 is scheduled. This field is mandatory present when ntn-Config is provided in dedicated configuration. If this field is absent in ntn-Config provided via NTN-NeighCellConfig the UE uses epoch time of the serving cell, otherwise the field is based on the timing of the serving cell, i.e. the SFN and sub-frame number indicated in this field refers to the SFN and sub-frame of the serving cell. In case of handover or conditional handover, this field is based on the timing of the target cell, i.e. the SFN and sub-frame number indicated in this field refers to the SFN and sub-frame of the target cell. For the target cell the UE considers epoch time, indicated by the SFN and sub-frame number in this field, to be the frame nearest to the frame in which the message indicating the epoch time is received. This field is excluded when determining changes in system information, i.e. changes to epochTime should neither result in system information change notifications nor in a modification of valueTag in SIB1.

Scheduling offset used for the timing relationships that are modified for NTN (see TS 38.213). The unit of the field K_offset is number of slots for a given subcarrier spacing of 15 kHz. If the field is absent UE assumes value 0.

Scheduling offset provided by network if downlink and uplink frame timing are not aligned at gNB. It is needed for UE action and assumption on downlink configuration indicated by a MAC CE command in PDSCH (see TS 38.213). If the field is absent UE assumes value 0. For the reference subcarrier spacing value for the unit of K_mac in FR1, a value of 15 kHz is used. The unit of K_mac is number of slots for a given subcarrier spacing.

If present, this parameter indicates polarization information for downlink transmission on service link: including Right hand, Left hand circular polarizations (RHCP, LHCP) and Linear polarization.

If present, this parameter indicates Polarization information for uplink service link. If not present and ntn-PolarizationDL is present, UE assumes the same polarization for UL and DL.

A validity duration configured by the network for assistance information (i.e. Serving and/or neighbour satellite ephemeris and Common TA parameters) which indicates the maximum time duration (from epochTime) during which the UE can apply assistance information without having acquired new assistance information. The unit of ntn-UlSyncValidityDuration is second. Value s5 corresponds to 5 s, value s10 indicate 10 s and so on. This parameter applies to both connected and idle mode UEs. If this field is absent in ntn-Config provided via NTN-NeighCellConfig, the UE uses validity duration from the serving cell assistance information. This field is excluded when determining changes in system information, i.e. changes of ntn-UlSyncValidityDuration should neither result in system information change notifications nor in a modification of valueTag in SIB1. ntn-UlSyncValidityDuration is only updated when at least one of epochTime, ta-Info, ephemerisInfo is updated.

Network-controlled common timing advanced value and it may include any timing offset considered necessary by the network. ta-Common with value of 0 is supported. The granularity of ta-Common is 4.072 × 10^(-3) μs. Values are given in unit of corresponding granularity. This field is excluded when determining changes in system information, i.e. changes of ta-Common should neither result in system information change notifications nor in a modification of valueTag in SIB1.

Indicate drift rate of the common TA. The granularity of ta-CommonDrift is 0.2 × 10^(-3) μs/s. Values are given in unit of corresponding granularity. This field is excluded when determining changes in system information, i.e. changes of ta-CommonDrift should neither result in system information change notifications nor in a modification of valueTag in SIB1.

Indicate drift rate variation of the common TA. The granularity of ta-CommonDriftVariant is 0.2×10^(-4) μs/s^2. Values are given in unit of corresponding granularity. This field is excluded when determining changes in system information, i.e. changes of ta-CommonDriftVariant should neither result in system information change notifications nor in a modification of valueTag in SIB1.

When this field is included in SIB19, it indicates reporting of timing advanced is enabled during Random Access due to RRC connection establishment or RRC connection resume, and during RRC connection reestablishment. When this field is included in ServingCellConfigCommon within dedicated signalling, it indicates TA reporting is enabled during Random Access due to reconfiguration with sync (see clause 5.4.8 of TS 38.321).

Periodicity and slot offset sl1 corresponds to a periodicity of 1 slot, sl2 to a periodicity of two slots, and so on. The corresponding offset is also given in number of slots (see clause 5.2.2.3.1 of TS 38.214).

For aperiodicTriggeringOffset, the value 0 corresponds to 0 slots, value 1 corresponds to 1 slot, value 2 corresponds to 2 slots, value 3 corresponds to 3 slots, value 4 corresponds to 4 slots, value 5 corresponds to 16 slots, value 6 corresponds to 24 slots. For aperiodicTriggeringOffset-r16 and aperiodicTriggeringOffset-r17, the value indicates the number of slots. aperiodicTriggeringOffset-r17 is applicable to SCS 480 kHz and 960 kHz, and only the values of integer multiples of 4 are valid, i.e. 0, 4, 8, and so on. The network configures only one of the fields. When neither field is included, the UE applies the value 0.

Maximum total number in Group 1 and Group 2 is 8 (see clauses 5.2.1.4.1 and 5.2.1.4.2 of TS 38.214).

Indicates that this NZP-CSI-RS-ResourceSet, if configured also with trs-Info, is used for propagation delay compensation. The field can be present only if trs-info is present.

If the field is set to off or if the field is absent, the UE may not assume that the NZP-CSI-RS resources within the resource set are transmitted with the same downlink spatial domain transmission filter (see clauses 5.2.2.3.1 and 5.1.6.1.2 of TS 38.214). It can only be configured for CSI-RS resource sets which are associated with CSI-ReportConfig with report of L1 RSRP, L1 SINR or "no report".
