Definition

The IE OD-SSB-Config is used to configure the OD-SSB activated by od-ssb-ActivationStatus or by a MAC CE see TS 38.321 [3], clause 6.1.3.88.

Fields (10)

FieldDescription
od-SSB-ConfigId-r19
OD-SSB-ConfigId-r19
since v19.1.0
od-SSB-SFN-Offset-r19
INTEGER (0..15) · OPTIONAL Need S
since v19.1.0
Indicates SFN offset, where SFN refers to the SFN of this serving cell (see TS 38.213 [13], clause 4.4). The network configures this field according to the field od-SSB-Periodicity such that the indicated system frame does not exceed the OD-SSB periodicity. If the field is absent, the UE applies the value 0.
od-SSB-HalfFrameIndex-r19
ENUMERATED {zero, one} · OPTIONAL Need S
since v19.1.0
Indicates whether OD-SSB is in the first half or the second half of the frame. If the field is absent, the UE applies the value zero .
od-SSB-ActivationStatus-r19
ENUMERATED {activated} · OPTIONAL Need S
since v19.1.0
Indicates the activation status of this OD-SSB pattern upon configuration. Only one OD-SSB pattern can be activated at one point of time. If the field is absent, the activation status of this OD-SSB pattern upon configuration is deactivated.
od-SSB-Periodicity-r19
ENUMERATED { ms5, ms10, ms20, ms40, ms80, ms160, spare2, spare1 }
since v19.1.0
The SSB periodicity for the OD-SSB in ms. If absoluteFrequencySSB is configured in servingCellConfigCommon , the network may only configure values smaller than or equal to the periodicity associated for the absoluteFrequencySSB ( ssb-periodicityServingCell configured in ServingCellConfigCommon ).
od-SSB-PositionsInBurst-r19
CHOICE { · OPTIONAL Cond ODssbAOssb
since v19.1.0
Indicates the time domain positions of the transmitted SS-blocks for OD-SSB in a half frame with SS/PBCH blocks as defined in TS 38.213 [13], clause 4.1. If absent, UE applies the value ssb-PositionsInBurst provided in ServingCellConfigCommon .
shortBitmap
BIT STRING (SIZE (4))
since v19.1.0
mediumBitmap
BIT STRING (SIZE (8))
since v19.1.0
longBitmap
BIT STRING (SIZE (64))
since v19.1.0
od-SSB-NrofBursts-r19
ENUMERATED {n5, n10, n15, n20, n25, n30, n40, n50, n75, n100, n150, n200} · OPTIONAL Cond MACCE
since v19.1.0
Indicates the number of OD-SSB bursts to be transmitted after OD-SSB is activated. Network only configures this field when od-SSB-ActivationStatus is absent. For FR1, the value range is {5, 10, 15, 20, 25, 30, 40, 50}. For FR2, the value range is {25, 30, 40, 50, 75, 100, 150, 200}.
