Inequality A4-1 (Entering condition)

Mn + Ofn + Ocn – Hys > Thresh

Inequality A4-2 (Leaving condition)

Mn + Ofn + Ocn + Hys < Thresh

The variables in the formula are defined as follows:

Mn is the measurement result of the neighbouring cell, not taking into account any offsets.

Ofn is the measurement object specific offset of the neighbour cell (i.e. offsetMO as defined within measObjectNR corresponding to the neighbour cell).

Ocn is the measurement object specific offset of the neighbour cell (i.e. cellIndividualOffset as defined within measObjectNR corresponding to the neighbour cell), and set to zero if not configured for the neighbour cell.

Hys is the hysteresis parameter for this event (i.e. hysteresis as defined within reportConfigNR for this event).

Thresh is the threshold parameter for this event (i.e. a4-Threshold as defined within reportConfigNR for this event).

Mn is expressed in dBm in case of RSRP, or in dB in case of RSRQ and RS-SINR.

Ofn, Ocn, Hys are expressed in dB.

Thresh is expressed in the same unit as Mn.

2> if the reportType is set to eventTriggered or periodical:

3> set the measResultNeighCells to include the best neighbouring cells up to maxReportCells in accordance with the following:

4> if the reportType is set to eventTriggered:

5> include the cells included in the cellsTriggeredList as defined within the VarMeasReportList for this measId;

…

4> for each cell that is included in the measResultNeighCells, include the physCellId;

7> set results SSB-Cell within the measResult to include the SS/PBCH block based quantity(ies) indicated in the reportQuantityCell within the concerned reportConfig, in order of decreasing trigger quantity, i.e. the best cell is included first:

…

1> increment the numberOfReportsSent as defined within the VarMeasReportList for this measId by 1;

1> stop the periodical reporting timer, if running;

1> if the numberOfReportsSent as defined within the VarMeasReportList for this measId is less than the reportAmount as defined within the corresponding reportConfig for this measId:

2> start the periodical reporting timer with the value of reportInterval as defined within the corresponding reportConfig for this measId;

8.1.3.1.8 Measurement configuration control and reporting / Event A5 / Measurement of Neighbour NR cell / Intra-frequency measurements

8.1.3.1.8.1 Test Purpose (TP)

(1)

with { UE in NR RRC_CONNECTED state and intra-frequency measurements configured for event A5 with event based periodical reporting }

ensure that {

when { Serving cell becomes worse than absolute threshold1 and neighbour cell becomes better than absolute threshold2 }

then { UE sends MeasurementReport message at regular intervals while entering conditions for event A5 are satisfied }

}

(2)

with { UE in NR RRC_CONNECTED state and periodical measurement reporting triggered by event A5 ongoing }

ensure that {

when { Serving cell becomes better than absolute threshold1 or neighbour cell becomes worse than absolute threshold2 }

then { UE stops sending MeasurementReport message }

}

8.1.3.1.8.2 Conformance requirements

References: The conformance requirements covered in the current TC are specified in: TS 38.331, clauses 5.3.5.3, 5.5.2.1, 5.5.4.1, 5.5.4.6 and 5.5.5.1. Unless otherwise stated these are Rel-15 requirements.

[TS 38.331, clause 5.3.5.3]

The UE shall perform the following actions upon reception of the RRCReconfiguration:

…

1> if the RRCReconfiguration message includes the measConfig:

2> perform the measurement configuration procedure as specified in 5.5.2;

…

1> if the UE is configured with E-UTRA nr-SecondaryCellGroupConfig (MCG is E-UTRA):

…

1> else:

2> submit the RRCReconfigurationComplete message via SRB1 to lower layers for transmission using the new configuration;

…

[TS 38.331, clause 5.5.2.1]

…

The UE shall:

…

1> if the received measConfig includes the measObjectToAddModList:

2> perform the measurement object addition/modification procedure as specified in 5.5.2.5;

…

1> if the received measConfig includes the reportConfigToAddModList:

2> perform the reporting configuration addition/modification procedure as specified in 5.5.2.7;

…

1> if the received measConfig includes the measIdToAddModList:

2> perform the measurement identity addition/modification procedure as specified in 5.5.2.3;

…

[TS 38.331, clause 5.5.4.1]

If AS security has been activated successfully, the UE shall:

1> for each measId included in the measIdList within VarMeasConfig:

2> if the corresponding reportConfig includes a reportType set to eventTriggered or periodical;

3> if the corresponding measObject concerns NR;

…

4> if the eventA3 or eventA5 is configured in the corresponding reportConfig:

5> if a serving cell is associated with a measObjectNR and neighbours are associated with another measObjectNR, consider any serving cell associated with the other measObjectNR to be a neighbouring cell as well;
