PosSI-SchedulingInfo field descriptions

areaScope

Indicates that a posSIB is area specific. If the field is absent, the posSIB is cell specific.

encrypted

The presence of this field indicates that the pos-sib-type is encrypted as specified in TS 37.355 [49].

gnss-id

The presence of this field indicates that the positioning SIB type is for a specific GNSS. Indicates a specific GNSS (see also TS 37.355 [49])

posSI-BroadcastStatus

Indicates if the SI message is being broadcasted or not. Change of posSI-BroadcastStatus should not result in system information change notifications in Short Message transmitted with P-RNTI over DCI (see clause 6.5). The value of the indication is valid until the end of the BCCH modification period when set to broadcasting.

posSI-RequestConfig

Configuration of Msg1 resources that the UE uses for requesting SI-messages for which posSI-BroadcastStatus is set to notBroadcasting.

posSI-RequestConfigRedCap

Configuration of Msg1 resources for initialUplinkBWP-RedCap that the RedCap UE uses for requesting SI-messages for which posSI-BroadcastStatus is set to notBroadcasting.

posSI-RequestConfigSUL

Configuration of Msg1 resources that the UE uses for requesting SI-messages for which posSI-BroadcastStatus is set to notBroadcasting.

posSIB-MappingInfo

List of the posSIBs mapped to this SystemInformation message.

posSibType

The positioning SIB type is defined in TS 37.355 [49].

posSI-Periodicity

Periodicity of the SI-message in radio frames, such that rf8 denotes 8 radio frames, rf16 denotes 16 radio frames, and so on. If the offsetToSI-Used is configured, the posSI-Periodicity of rf8 cannot be used.

offsetToSI-Used

This field, if present indicates that all the SI messages in posSchedulingInfoList are scheduled with an offset of 8 radio frames compared to SI messages in schedulingInfoList. offsetToSI-Used may be present only if the shortest configured SI message periodicity for SI messages in schedulingInfoList is 80ms. If SI offset is used, this field is present in each of the SI messages in the posSchedulingInfoList.

sbas-id

The presence of this field indicates that the positioning SIB type is for a specific SBAS. Indicates a specific SBAS (see also TS 37.355 [49]).

Conditional presence	Explanation
MSG-1	The field is optionally present, Need R, if posSI-BroadcastStatus is set to notBroadcasting for any SI-message included in PosSchedulingInfo. It is absent otherwise.
SUL-MSG-1	The field is optionally present, Need R, if supplementaryUplink is configured in ServingCellConfigCommonSIB and if posSI-BroadcastStatus is set to notBroadcasting for any SI-message included in PosSchedulingInfo. It is absent otherwise.
REDCAP-MSG-1	The field is optionally present, Need R, if initialUplinkBWP-RedCap is configured in UplinkConfigCommonSIB and if posSI-BroadcastStatus is set to notBroadcasting for any SI-message included in PosSchedulingInfo. It is absent otherwise.

– SIBpos

The IE SIBpos contains positioning assistance data as defined in TS 37.355 [49].
