EphemerisInfo
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.
|
epochTime
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.

ntn-UlSyncValidityDuration

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.

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.

NZP-CSI-RS-ResourceSet field descriptions |
---|
aperiodicTriggeringOffset, aperiodicTriggeringOffset-r16, aperiodicTriggeringOffset-r17
Offset X between the slot containing the DCI that triggers a set of aperiodic NZP CSI-RS resources and the slot in which the CSI-RS resource set is transmitted. 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.
|
aperiodicTriggeringOffsetL2
Indicates triggering offset of aperiodic NZP CSI-RS resources used for fast activation of the SCell (see clause 5.2.1.5.3 of TS 38.214), when the NZP CSI-RS resources are activated by the MAC CE (see clause 5.9 of TS 38.321). The value indicates the number of slots.
|
cmrGroupingAndPairing
Configures CMR groups and pairs. The first nrofResourcesGroup1 resources in the NZP-CSI-RS resource set belong to Group 1 and the remaining resources in the NZP-CSI-RS resource set belong to Group 2. nrofResourcesGroup1 is K_1 and the number of remaining resources in the NZP-CSI-RS resource set belonging to Group 2 is K_2 as specified in clause 5.2.1.4.1 of TS 38.214. 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).
|
pair1OfNZP-CSI-RS, pair2OfNZP-CSI-RS
A pair of NZP CSI-RS resources. In one pair, one resource shall belong to group 1 and the other resource shall belong to group 2 as configured by nrofResourcesGroup1 and nrofResourcesGroup2. (see clause xx of TS 38.214).
|
nzp-CSI-RS-Resources
NZP-CSI-RS-Resources associated with this NZP-CSI-RS resource set (see clause 5.2 of TS 38.214). For CSI, there are at most 8 NZP CSI RS resources per resource set.
|
nzp-CSI-RS-ResourceId1, nzp-CSI-RS-ResourceId2
The nzp-CSI-RS-ResourceId1-r17 represents the index of the NZP CSI-RS resource in Resource Group 1, and nzp-CSI-RS-ResourceId2-r17 represents the index of the NZP CSI-RS resource in Resource Group 2.
|
pdc-Info
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. The field can be present in only one NZP-CSI-RS-ResourceSet. If network configures this field for an NZP-CSI-RS-ResourceSet, the UE measures the UE Rx-Tx time difference based on resources configured in this resource set.
|
repetition
Indicates whether repetition is on/off. 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".
|
trs-Info
Indicates that the antenna port for all NZP-CSI-RS resources in the CSI-RS resource set is same. If the field is absent or released the UE applies the value false (see clause 5.2.2.3.1 of TS 38.214).
