 –  NTN-Configp. 866

The IE NTN-Config provides parameters needed for the UE to access NR via NTN access.
NTN-Config information element
NTN-Config field descriptions
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.
cellSpecificKoffset
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.
kmac
Scheduling offset provided by network if downlink and uplink frame timing are not aligned at gNB. If the field is absent UE assumes value 0. In FR1, the unit of kmac is number of slots for a given subcarrier spacing of 15 kHz.
ntn-PolarizationDL
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.
ntn-PolarizationUL
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.
ntn-UlSyncValidityDuration
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.
ta-Common
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.
ta-CommonDrift
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.
ta-CommonDriftVariant
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.
ta-Report
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).
Conditional Presence Explanation
SIB19The field is mandatory present for the serving cell in SIB19. The field is optionally present, Need R, otherwise.

controlResourceSetToAddModList, controlResourceSetToAddModListSizeExt
List of UE specifically configured Control Resource Sets (CORESETs) to be used by the UE. The network restrictions on configuration of CORESETs per DL BWP are specified in clause 10.1 of TS 38.213, and TS 38.306. The UE shall consider entries in controlResourceSetToAddModList and in controlResourceSetToAddModListSizeExt as a single list, i.e. an entry created using controlResourceSetToAddModList can be modified using controlResourceSetToAddModListSizeExt (or deleted using controlResourceSetToReleaseListSizeExt) and vice-versa. In case network reconfigures control resource set with the same ControlResourceSetId as used for commonControlResourceSet or commonControlResourceSetExt configured via PDCCH-ConfigCommon or via SIB20, the configuration from PDCCH-Config always takes precedence and should not be updated by the UE based on servingCellConfigCommon or based on SIB20.
controlResourceSetToReleaseList, controlResourceSetToReleaseListSizeExt
List of UE specifically configured Control Resource Sets (CORESETs) to be released by the UE.

PDCCH-ConfigCommon information element
PDCCH-ConfigCommon field descriptions
commonControlResourceSet
An additional common control resource set which may be configured and used for any common or UE-specific search space. If the network configures this field, it uses a ControlResourceSetId other than 0 for this ControlResourceSet. The network configures the commonControlResourceSet in SIB1 so that it is contained in the bandwidth of CORESET#0. If the RedCap-specific initial downlink BWP does not contain the entire CORESET#0, the network configures the commonControlResourceSet in the RedCap-specific initial downlink BWP in SIB1 for RedCap such that it does not have to be contained in the bandwidth of CORESET#0.
commonSearchSpaceList, commonSearchSpaceListExt, commonSearchSpaceListExt2
A list of additional common search spaces. If the network configures this field, it uses the SearchSpaceIds other than 0. If the field is included, it replaces any previous list, i.e. all the entries of the list are replaced and each of the SearchSpace entries is considered to be newly created and the conditions and Need codes for setup of the entry apply. If the network includes commonSearchSpaceListExt/commonSearchSpaceListExt2, it includes the same number of entries, and listed in the same order, as in commonSearchSpaceList.
controlResourceSetZero
Parameters of the common CORESET#0 which can be used in any common or UE-specific search spaces. The values are interpreted like the corresponding bits in MIB pdcch-ConfigSIB1. Even though this field is only configured in the initial BWP (BWP#0) controlResourceSetZero can be used in search spaces configured in other DL BWP(s) than the initial DL BWP if the conditions defined in clause 10 of TS 38.213 are satisfied.
firstPDCCH-MonitoringOccasionOfPEI-O
Offset, in number of symbols, from the start of the reference frame for PEI-O to the start of the first PDCCH monitoring occasion of PEI-O on this BWP, see clause 10.4A of TS 38.213. For the case po-NumPerPEI is smaller than Ns, UE applies the (floor(i_s/po-NumPerPEI)+1)-th value out of (N_s/po-NumPerPEI) configured values in firstPDCCH-MonitoringOccasionOfPEI-O for the symbol-level offset. When po-NumPerPEI is one or multiple of Ns, UE applies the first configured value in firstPDCCH-MonitoringOccasionOfPEI-O for the symbol-level offset.
firstPDCCH-MonitoringOccasionOfPO
Indicates the first PDCCH monitoring occasion of each PO of the PF on this BWP, see TS 38.304.

 –  PDSCH-TimeDomainResourceAllocationListp. 901

The IE PDSCH-TimeDomainResourceAllocation is used to configure a time domain relation between PDCCH and PDSCH. The PDSCH-TimeDomainResourceAllocationList contains one or more of such PDSCH-TimeDomainResourceAllocations. The network indicates in the DL assignment which of the configured time domain allocations the UE shall apply for that DL assignment. The UE determines the bit width of the DCI field based on the number of entries in the PDSCH-TimeDomainResourceAllocationList. Value 0 in the DCI field refers to the first element in this list, value 1 in the DCI field refers to the second element in this list, and so on.
