Overview
2.1 Definition Auto Neighbor Group Configuration (ANGC) evaluates the overlap relationship between neighboring cells based on the measurement event statistics of a network. This ensures that the eNodeB can automatically configure the attributes of required neighboring cells. This feature is comprised of the following functions, which can be separately activated: l
ANGC for carrier aggregation (CA) ANGC for CA supports automatic configuration of the SCell blind configuration flag CaGroupSCellCfg.SCellBlindCfgFlag.
l
ANGC for mobility load balancing (MLB) ANGC for MLB supports automatic configuration of the overlap indicator EutranInterFreqNCell.OverlapInd for an inter-frequency neighboring cell.
l
ANGC for time domain enhanced inter-cell interference coordination (TDM eICIC) ANGC for TDM eICIC can automatically group cells into clusters and configure EutranIntraFreqNCell.AttachCellSwitch to specify the association between a macro cell and a micro cell.
2.2 Benefits ANGC supports automatic configuration of the SCell blind configuration flag CaGroupSCellCfg.SCellBlindCfgFlag, and the overlap indicator EutranInterFreqNCell.OverlapInd, and the association between a macro cell and a micro cell EutranIntraFreqNCell.AttachCellSwitch on an eNodeB. This feature saves the workload of manual parameter configuration and improves the operation and maintenance efficiency.

3.2 MR Collection 3.2.1 Operations in a Measurement Period After the automatic configuration of the SCell blind configuration flag CaGroupSCellCfg.SCellBlindCfgFlag is enabled, the eNodeB automatically collects sufficient measurement reports (MRs) of each secondary component carrier (SCC) that can be used as a serving cell, estimates the coverage relationship, and configures the blind configuration flags CaGroupScellCfg.ScellBlindCfgFlag for SCells. NOTE
After this function is enabled, the eNodeB collects only the MRs of SCCs whose SccFreqCfg.CtrlMode is set to AUTO. If SccFreqCfg.CtrlMode of an SCC is set to MANUAL, the eNodeB does not collect the MRs of the SCC. In this scenario, ANGC for CA does not take effect on the SCC.
At the end of a measurement period specified by CaMgtCfg.StatPeriod, if the total number of MRs collected from an SCC that can be used as the serving cell is greater than or equal to the number of samples collected from an SCell with a blind configuration flag, the eNodeB continues to evaluate the coverage relationship. The number of samples is specified by CaMgtCfg.BlindScellSampleNum. For details, see 3.3 Coverage Relationship Evaluation. Otherwise, the eNodeB must perform a supplementary measurement. For details, see 3.2.2 Supplementary Measurement.

NOTE
The CaMgtCfg.BlindScellSampleNum parameter can be adjusted as required based on the following counters: l
L.CA.DLSCell.Add.Meas.Succ, which indicates the number of successful A4-measurementbased SCell configurations for CA UEs
l
L.InterFreq.Load.MeasSucc.Num.Cell, which indicates the number of successful load-triggered inter-frequency measurements
l
L.HHO.InterFreq.Service.PrepAttOut, which indicates the number of service-based interfrequency handover preparation attempts
l
L.HHO.InterFreq.MBMSInterest.PrepAttOut, which indicates the number of inter-frequency outgoing handover preparation attempts triggered by interests in MBMS services
MRs collected by this function are related to the following events: l
Inter-frequency measurement event A4 for CA NOTE
If the serving cell has an inter-frequency neighboring cell whose SCellBlindCfgFlag is set to TRUE(TRUE), the serving cell will not collect from the neighboring cell the MRs that are sourced from A4 measurements triggered by CA.
l
Inter-frequency measurement event A4 for MLB
l
Inter-frequency measurement event A4 or A5 for service-based inter-frequency handovers
l
Inter-frequency measurement event A4 or A5 for inter-frequency handovers based on multimedia broadcast multicast service (MBMS) interest indication
l
Strongest-cell measurement event triggered for a supplementary measurement or fast ANR
If an MR is not sourced from inter-frequency measurement events triggered by CA, it can be regarded as a valid sample only when the threshold for inter-frequency measurement events triggered by CA is reached. This threshold is calculated using the following formula: Threshold for inter-frequency measurement events triggered by CA = CaMgtCfg.CarrAggrA4ThdRsrp + SccFreqCfg.SccA4Offset
3.2.2 Supplementary Measurement NOTE
l Supplementary measurement in a cell takes effect on UEs that are newly admitted to this cell or handed over to this cell. l The number of UEs involved in supplementary measurement are restricted as follows: - Maximum number of UEs that perform measurements simultaneously, which is specified by ANR.FastAnrIntraRatMeasUeNum - Maximum number of UEs that perform measurements per minute, which is specified by ANR.FastAnrIntraRatUeNumThd l The interval at which supplementary measurement reports are sent is specified by ANR.FastAnrRprtInterval.
At the end of a measurement period specified by CaMgtCfg.StatPeriod, if the total number of MRs collected from an SCC that can be used as the serving cell is less than the number of samples collected from an SCell with blind configuration flags, the eNodeB can determine whether to extend another measurement period to collect more samples. The number of samples is specified by CaMgtCfg.BlindScellSampleNum, and the setting of CaMgtCfg.AddedMeasCfg determines the measurement period to collect samples. Issue 04 (2016-09-05)

When CaMgtCfg.AddedMeasCfg is set to ALLOWED, the eNodeB automatically starts an extension period of the same length as the measurement period specified by CaMgtCfg.StatPeriod. In this extension period, the eNodeB proactively delivers measurement tasks to collect MRs from UEs, and adds the MRs to the existing samples. –
If the number of accumulated samples is equal to the number of samples collected from SCells with blind configuration flags, as specified by CaMgtCfg.BlindScellSampleNum, the eNodeB stops delivering measurement tasks. However, it still collects MRs from UEs until the extended period ends, and evaluates the coverage relationship.
–
If the number of accumulated samples is still less than the value of CaMgtCfg.BlindScellSampleNum when the extension period elapses, the eNodeB does not evaluate the coverage relationship. The automatic configuration of SCell blind configuration flags then enters a sleep state, awaiting re-triggering. For details, see 3.5 Sleep State and Sleep Period.
When CaMgtCfg.AddedMeasCfg is set to NOT_ALLOWED, the eNodeB automatically starts an extension period of the same length as the measurement period specified by CaMgtCfg.StatPeriod. In this extension period, the eNodeB does not proactively deliver measurement tasks but continues to collect MRs reported by UEs, and adds the MRs to the existing samples. NOTE
When CaMgtCfg.AddedMeasCfg is set to NOT_ALLOWED, one of the following conditions must be fulfilled to continue collecting MRs reported by UEs: l Adaptive CA is enabled and the SCell blind configuration flag is not used. Both conditions must be met simultaneously. For details, see Carrier Aggregation Feature Parameter Description. The FreqCfgSwitch and AdpCaSwitch options of the ENodeBAlgoSwitch.CaAlgoSwitch parameter are selected. CaGroupSCellCfg is not configured for any cell in SccFreqCfg.SccDlEarfcn, or CaGroupSCellCfg.ScellBlindCfgFlag is set to False. l Connected-mode MLB is enabled. For details, see Intra-RAT Mobility Load Balancing Feature Parameter Description. The InterFreqMlbSwitch or InterFreqBlindMlbSwitch option of the CellAlgoSwitch.MlbAlgoSwitch parameter is selected. If CellMLB.MlbTriggerMode is set to PRB_ONLY(PrbMode) or UE_NUMBER_ONLY, CellMLB.InterFreqUeTrsfType is set to SynchronizedUE. l The service-based inter-frequency handover is activated. That is, both the ServiceBasedInterFreqHoSwitch option of ENodeBAlgoSwitch.HoAlgoSwitch and the SrvBasedInterFreqHoSw option of CellAlgoSwitch.HoAllowedSwitch are selected. For details, see Intra-RAT Mobility Management in Connected Mode Feature Parameter Description. l The inter-frequency handover based on eMBMS service interest indication is activated because the CELLMBMSCFG.MBMSServiceSwitch option is selected. For details, see eMBMS Feature Parameter Description.
3.3 Coverage Relationship Evaluation At the end of a measurement period or an extended measurement period, if the number of MRs collected from an SCC that can be used as the serving cell is greater than or equal to the number of samples collected from an SCell with blind configuration, the eNodeB evaluates the coverage relationships with all neighboring cells related to the SCC based on the following formula. The number of samples is specified by Issue 04 (2016-09-05)

CaMgtCfg.BlindScellSampleNum. Based on the evaluation result, the eNodeB determines whether to add, modify, or delete the SCell blind configuration flags for the inter-frequency neighboring cell. For details, see 3.4 Decision and Configuration Implementation. Overlap percentage between an inter-frequency neighboring cell and the serving cell = (Number of times an inter-frequency neighboring cell serves as the first reported object in MRs/Number of samples collected from the frequency) x 100%
3.4 Decision and Configuration Implementation Decision Check whether the SCell blind configuration flag CaGroupScellCfg.ScellBlindCfgFlag is set. CaGroupScellCfg.ScellBlindCfgFlag can be set to FALSE(FALSE) or TRUE(TRUE). l
The eNodeB adds the CaGroupSCellCfg MO for an inter-frequency neighboring cell and sets CaGroupSCellCfg.SCellBlindCfgFlag to TRUE if the overlap percentage between the inter-frequency neighboring cell and the serving cell is greater than or equal to the threshold for adding the SCell blind configuration flag. The threshold is specified by SccFreqCfg.BlindScellAddThd.
l
The eNodeB modifies the SCell blind configuration flag for an inter-frequency neighboring cell with an SCell blind configuration flag set to FALSE if the overlap percentage between the inter-frequency neighboring cell and the serving cell is greater than or equal to the threshold for adding the flag. The threshold is specified by SccFreqCfg.BlindScellAddThd.
l
The eNodeB deletes an SCell blind configuration flag and the MO CaGroupSCellCfg MO from an inter-frequency neighboring cell with the SCell blind configuration flag set to True if the overlap percentage between the inter-frequency neighboring cell and the serving cell is less than the threshold for deleting the flag. The threshold is specified by SccFreqCfg.BlindScellDelThd.
Configuration Implementation Configuration implementation takes effect only for the inter-frequency neighboring cell of the SCC where SCCFreqCfg.CtrlMode is set to AUTO. If SCCFreqCfg.CtrlMode is set to MANUAL, configuration implementation cannot be completed. Configuration implementation is controlled by CaMgtCfg.OptMode, which can be set to FREE or CONTROLLED. l
If CaMgtCfg.OptMode is set to FREE, the eNodeB can automatically add, modify, or delete the SCell blind configuration flag CaGroupScellCfg.ScellBlindCfgFlag after the decision takes effect.
l
If CaMgtCfg.OptMode is set to CONTROLLED, the eNodeB sends the decision as modification advice to the U2000 after the decision takes effect. On the U2000, choose SON > LTE CA (traditional style) or double-click SON on the Application Center tab page. Then, choose Self Optimization > LTE CA (application style). The LTE CA tab page is displayed. The SCell blind configuration flag specified by CaGroupScellCfg.ScellBlindCfgFlag can be added, modified, or deleted only after manual acknowledgment.

l
If the decision indicates that a blind configuration flag must be added, the eNodeB adds the MO and sets CaGroupScellCfg.ScellBlindCfgFlag to TRUE(TRUE).
l
If the decision indicates that a blind configuration flag must be modified, the eNodeB changes the value of CaGroupScellCfg.ScellBlindCfgFlag to TRUE(TRUE).
l
If the decision indicates that a blind configuration flag must be deleted, the eNodeB deletes CaGroupScellCfg.
After configuration implementation is complete, Auto Neighbor Group Configuration for CA enters the sleep state. For details, see 3.5 Sleep State and Sleep Period.
3.5 Sleep State and Sleep Period Sleep State ANGC for CA in the sleep state does not collect MRs, evaluate the coverage relationship, or perform operations such as decision and configuration implementation. Automatic configuration of SCell blind configuration flags is restarted if one of the following conditions is fulfilled: l
An inter-frequency neighboring cell of the serving cell is added or deleted.
l
The value of CaMgtCfg.StatPeriod is changed.
l
BlindScellAutoSwitch in the CellAlgoSwitch.CaAutoGroupSwitch parameter is selected again.
l
BlindScellAutoSwitch in the CellAlgoSwitch.CaAutoGroupSwitch parameter is selected during cell reestablishment.
Sleep Period The proper configuration of CaMgtCfg.SleepPeriod can prevent the function from being frequently restarted due to adding or deleting an inter-frequency neighboring cell for the serving cell. Specifically, when supplementary measurement is allowed and the network topology is changed frequently in a short period (for example, the network is optimized and adjusted many times in a period), a proper value should be set for CaMgtCfg.SleepPeriod to prevent the function from being repeatedly triggered, reducing the number of supplementary measurements delivered by the eNodeB. In the sleep period, the change of an inter-frequency neighbor relationship does not cause ANGC for CA to be activated immediately. It will be activated only at the end of the sleep period. NOTE
The sleep period is not used when CaMgtCfg.SleepPeriod is set to 0. If an inter-frequency neighbor relationship changes in this scenario, automatic configuration of SCell blind configuration flags in the sleep state is restarted. If CaMgtCfg.SleepPeriod is set to 65535, automatic configuration of SCell blind configuration flags is periodically started and will not stop. In such a case, supplementary measurement is not recommended. If supplementary measurement is mandatory, use it less by adopting the following methods:
Issue 04 (2016-09-05)
l
Set the measurement period CaMgtCfg.StatPeriod to a larger value.
l
Set the number of SCell blind configuration samples CaMgtCfg.BlindScellSampleNum to a smaller value.

4.2 Automatic Configuration of Overlap Indicators in Macro-Macro Networking Scenarios 4.2.1 MR Collection 4.2.1.1 Operations in a Measurement Period After automatic configuration of EutranInterFreqNCell.OverlapInd is enabled, the eNodeB collects sufficient MRs about each potential target frequency of inter-frequency MLB (that is, inter-frequency EARFCN of the serving cell) in a measurement period specified by CellMlbAutoGroup.StatPeriod. Based on the collected MRs, the eNodeB evaluates the coverage relationship and automatically sets the overlap indicator EutranInterFreqNCell.OverlapInd. NOTE
ANGC for MLB takes effect only on neighboring cells whose EutranInterFreqNCell.CtrlMode is set to AUTO_MODE. If EutranInterFreqNCell.CtrlMode is set to MANUAL_MODE for a neighboring cell, the MRs of the neighboring cell will not be collected. That is, ANGC for MLB does not take effect on the neighboring cell.

At the end of a measurement period (specified by CellMlbAutoGroup.StatPeriod), if the total number of sample MRs about a potential target frequency of inter-frequency MLB reaches or exceeds the threshold specified by CellMlbAutoGroup.OverlapIndAutoSampleNum, the eNodeB continues to evaluate the coverage relationship. For details, see 4.2.2 Coverage Relationship Evaluation. If the total number of sample MRs is lower than the threshold, the eNodeB instructs UEs to perform supplementary measurements as described in 4.2.1.2 Supplementary Measurement. NOTE
The CellMlbAutoGroup.OverlapIndAutoSampleNum parameter can be adjusted based on site conditions and the following counters: l
L.CA.DLSCell.Add.Meas.Succ, which indicates the number of successful A4-measurementbased SCell configurations for CA UEs
l
L.InterFreq.Load.MeasSucc.Num.Cell, which indicates the number of successful load-based inter-frequency measurements
l
L.HHO.InterFreq.Service.PrepAttOut, which indicates the number of service-based interfrequency handover preparation attempts
l
L.HHO.InterFreq.MBMSInterest.PrepAttOut, which indicates the number of outgoing interfrequency handover preparation attempts triggered by interests in MBMS services
MRs collected for automatic configuration of overlap indicators are related to the following events: l
Inter-frequency event A4 for CA
l
Inter-frequency event A4 for MLB
l
Inter-frequency event A4 or A5 for service-based inter-frequency handovers
l
Inter-frequency event A4 or A5 for inter-frequency handovers based on MBMS interest indication
l
Strongest-cell measurement event triggered for supplementary measurement or fast ANR
If an MR is not related to inter-frequency event A4 for MLB, the MR is valid only when the threshold for inter-frequency event A4 for MLB is reached. The threshold is calculated as follows: Threshold for inter-frequency event A4 for MLB = InterFreqHoGroup.InterFreqLoadBasedHoA4ThdRSRP + EutranInterNFreq.IfMlbThdRsrpOffset
4.2.1.2 Supplementary Measurement NOTE
l Supplementary measurement takes effect on UEs that newly access or are handed over to a network. l The number of UEs involved in supplementary measurement is limited: The maximum number of UEs that are measured simultaneously is specified by the ANR.FastAnrIntraRatMeasUeNum parameter. The maximum number of accumulated UEs that are measured in each minute is specified by the ANR.FastAnrIntraRatUeNumThd parameter. l The interval at which supplementary measurement reports are sent is specified by the ANR.FastAnrRprtInterval parameter.
At the end of a measurement period (specified by CellMlbAutoGroup.StatPeriod), if the total number of sample MRs about a potential target frequency of inter-frequency MLB is less than the threshold specified by CellMlbAutoGroup.OverlapIndAutoSampleNum, the Issue 04 (2016-09-05)

eNodeB may instruct UEs to perform supplementary measurements for collecting more samples, depending on the setting of CellMlbAutoGroup.AddedMeasCfg: l
If CellMlbAutoGroup.AddedMeasCfg is set to ALLOWED: The eNodeB automatically starts an extension period of the same length as the measurement period specified by CellMlbAutoGroup.StatPeriod. In this extension period, the eNodeB actively delivers measurement configurations to UEs, collects MRs from UEs, and adds the MRs to the existing samples.
l
–
Within the extension period, if the number of accumulated samples reaches the threshold specified by CellMlbAutoGroup.OverlapIndAutoSampleNum, the eNodeB stops proactive delivery of measurement configurations. However, it still collects MRs that are actively reported by UEs until the extension period ends. Then, the eNodeB continues to evaluate the coverage relationship.
–
If the number of accumulated samples is still less than the value of CellMlbAutoGroup.OverlapIndAutoSampleNum when the extension period elapses, the eNodeB will not evaluate the coverage relationship. Automatic configuration of overlap indicators enters the sleep state and can be triggered again. For details, see 4.2.5 Sleep State and Sleep Period.
If CellMlbAutoGroup.AddedMeasCfg is set to NOT_ALLOWED: The eNodeB automatically starts an extension period of the same length as the measurement period specified by CellMlbAutoGroup.StatPeriod. In this extension period, the eNodeB does not proactively deliver measurement configurations. However, it still collects MRs that are actively reported by UEs and adds the MRs to the existing samples. To continue collecting MRs reported by UEs, ensure that the following conditions must be met: –
Adaptive CA is enabled and the blind SCell configuration is disabled as follows (For details, see Carrier Aggregation Feature Parameter Description.): The FreqCfgSwitch and AdpCaSwitch options of the ENodeBAlgoSwitch.CaAlgoSwitch parameter are selected. CaGroupSCellCfg is not configured for any cell on the carrier identified by SccFreqCfg.SccDlEarfcn, or CaGroupSCellCfg.ScellBlindCfgFlag is set to False.
–
Connected-mode MLB is enabled as follows. For details, see Intra-RAT Mobility Load Balancing Feature Parameter Description. The InterFreqMlbSwitch or InterFreqBlindMlbSwitch option of the CellAlgoSwitch.MlbAlgoSwitch parameter is selected. CellMLB.MlbTriggerMode is set to PRB_ONLY(PrbMode) or UE_NUMBER_ONLY, and CellMLB.InterFreqUeTrsfType is set to SynchronizedUE.

4.2.2 Coverage Relationship Evaluation At the end of a measurement period or an extension period, if the total number of sample MRs about a potential target frequency of inter-frequency MLB reaches or exceeds the threshold specified by CellMlbAutoGroup.OverlapIndAutoSampleNum, the eNodeB evaluates the percentage of overlap between the serving cell and each inter-frequency neighboring cell on the frequency. Based on the overlap percentage, the eNodeB determines whether to add or delete an overlap indicator for each inter-frequency neighboring cell, as described in 4.2.3 Decision. The overlap percentage is calculated as follows: Percentage of overlap between an inter-frequency neighboring cell and the serving cell = (Number of MRs in which the neighboring cell ranks first/Total number of sample MRs about neighboring cells on the frequency) x 100% For example: Table 4-2 lists the MR samples collected from an inter-frequency EARFCN that can be used by the serving cell for MLB.

4.2.3 Decision If the overlap percentage for an inter-frequency neighboring cell whose EutranInterFreqNCell.OverlapInd has not been set is greater than or equal to the value of CellMlbAutoGroup.OverlapIndAddThd, the eNodeB determines that EutranInterFreqNCell.OverlapInd should be set to Yes for the inter-frequency neighboring cell. If the overlap percentage for an inter-frequency neighboring cell whose EutranInterFreqNCell.OverlapInd has been set is less than the value of CellMlbAutoGroup.OverlapIndDelThd, the eNodeB determines that EutranInterFreqNCell.OverlapInd should be set to No for the inter-frequency neighboring cell.
4.2.4 Configuration Execution Configuration execution takes effect only on neighboring cells whose EutranInterFreqNCell.CtrlMode is set to AUTO_MODE. If this parameter is set to MANUAL_MODE, the eNodeB does not execute configuration. The configuration mode is controlled by CellMlbAutoGroup.OptMode, which can be set to FREE or CONTROLLED. l
If this parameter is set to FREE, the eNodeB automatically adds or deletes the overlap indicator (EutranInterFreqNCell.OverlapInd) as determined.
l
If this parameter is set to CONTROLLED, the eNodeB sends the decision as modification advice to the U2000. On the U2000, choose SON > LTE MLB (traditional style) or double-click SON on the Application Center tab page, and then choose Self Optimization > LTE MLB (application style). The LTE MLB tab page is displayed. The overlap indicator specified by EutranInterFreqNCell.OverlapInd can be added or deleted only after manual acknowledgment.
When the execution is complete, ANGC for MLB enters the sleep state and waits to be triggered again. For details about the sleep state, see 4.2.5 Sleep State and Sleep Period.
4.2.5 Sleep State and Sleep Period Sleep State In the sleep state, automatic configuration of overlap indicators does not collect MRs, evaluate coverage relationships, makes configuration decisions, or execute configuration. This function is restarted if one of the following conditions is fulfilled: l
An inter-frequency neighboring cell of the serving cell is added or deleted.
l
The value of CellMlbAutoGroup.StatPeriod is changed.
l
The OverlapIndAutoSwitch option of the CellAlgoSwitch.MLBAutoGroupSwitch parameter is selected again.
l
The OverlapIndAutoSwitch option of the CellAlgoSwitch.MLBAutoGroupSwitch parameter is selected at cell reestablishment.
l
When the OverlapIndAutoSwitch option of the CellAlgoSwitch.MLBAutoGroupSwitch parameter is selected, the options MicroOverlapIndSwitch and MicroGroupOverlapIndSwitch of the CellAlgoSwitch.MlbAutoGroupSwitch parameter are selected again.

Sleep Period In a sleep period specified by CellMlbAutoGroup.SleepPeriod, automatic configuration of overlap indicators is in the sleep state. The setting of the period prevents the function from being frequently restarted owing to changes in inter-frequency neighbor relationships. Specifically, when supplementary measurement is allowed and the network topology is changed frequently within a short period (for example, the network is optimized and adjusted many times in a period), an appropriate setting of CellMlbAutoGroup.SleepPeriod helps reduce the number of supplementary measurements delivered by the eNodeB. Automatic configuration of overlap indicators will be activated only after the sleep period elapses. NOTE
The sleep period is invalid when CellMlbAutoGroup.SleepPeriod is set to 0. If an inter-frequency neighbor relationship changes when the sleep period is invalid, automatic configuration of overlap indicators in the sleep state is immediately restarted. When CellMlbAutoGroup.SleepPeriod is set to 65535, automatic configuration of overlap indicators is started periodically. In this scenario, supplementary measurement is not recommended. If supplementary measurement is required, reduce the number of supplementary measurements by using the following methods: l
Properly extend the measurement period (specified by CellMlbAutoGroup.StatPeriod)
l
Properly reduce the value of CellMlbAutoGroup.OverlapIndAutoSampleNum

5.2 MR Collection and Decision After automatic configuration of the cell attach switch EutranIntraFreqNCell.AttachCellSwitch is enabled, a micro cell takes the number of MRs of intra-frequency handover A3 events as the number of samples. It then calculates the proportion of each target macro cell serving as the strongest neighboring cell in the MRs of the micro cell. At the end of a measurement period (specified by CelleICIC.StatPeriod), automatic configuration of the cell attach switch is executed if both of the following conditions are met. For details, see 5.3 Configuration Implementation. If neither is met, the next measurement period starts. l
The number of collected samples is greater than or equal to the number of samples specified in CelleICIC.SampleNumTarget.
l
The proportion of the maximum number of samples on the target macro cell to the target number of samples is greater than or equal to the threshold for adding a homing relationship. This relationship is specified by CelleICIC.AttachCellAddThd.
5.3 Configuration Implementation The execution mode is controlled by the CelleICIC.WorkMode parameter. l
If the parameter is set to AUTO: When the start time specified by eNodeBSonDBCfg.StartTime arrives, the micro cell sends a request over the X2 interface to instruct the macro cell to modify the value of EutranIntraFreqNCell.AttachCellSwitch. After receiving the modification success message from the macro cell, the micro cell then modifies the value of EutranIntraFreqNCell.AttachCellSwitch.
l
If the parameter is set to CONTROLLED: The micro cell sends the decision as modification advice to the U2000 after the decision takes effect. On the U2000, choose SON > LTE eICIC (traditional style) or double-click SON on the Application Center tab page. Then, choose Self Optimization > LTE eICIC (application style). The LTE eICIC tab page is displayed. When it is confirmed that the start time specified in eNodeBSonDBCfg.StartTime arrives, the value of EutranIntraFreqNCell.AttachCellSwitch is changed.
EutranIntraFreqNCell.AttachCellSwitch is set to ON for a micro cell whose EutranIntraFreqNCell.AttachCellSwitch has not been configured. EutranIntraFreqNCell.AttachCellSwitch is changed to OFF for a micro cell whose EutranIntraFreqNCell.AttachCellSwitch has been configured because one micro cell can belong to only one macro cell. Then, EutranIntraFreqNCell.AttachCellSwitch of the micro cell is set to ON. After the configuration is complete, the eNodeB starts collecting MRs in the next measurement period. For details about the association between macro and micro cells, see TDM eICIC Feature Parameter Description. Issue 04 (2016-09-05)

ANGC for TDM eICIC has the following impacts on network performance: Adjusting the TDM eICIC association between macro and micro cells will change the application range of cell range expansion (CRE). As a result, the RRC connections of UEs will be re-established and a handover between macro and micro cells will be triggered, increasing the service drop rate and decreasing the intra-RAT handover success rate. Therefore, it is recommended that the association change time, as specified by eNodeBSonDBCfg.StartTime, be set in an off-peak hour.

Indicates whether this candidate secondary serving cell (SCell) can be configured as an SCell for carrier aggregation (CA) UEs in a blind manner. In CA-group-based configuration mode, this parameter takes effect if the SccBlindCfgSwitch option of the CaAlgoSwitch parameter is selected. In adaptive configuration mode, this parameter takes effect regardless of the SccBlindCfgSwitch setting. If this parameter is set to TRUE(TRUE), the eNodeB can configure this candidate SCell as an SCell for CA UEs in a blind manner, without delivering A4-related measurement configurations to CA UEs. If this parameter is set to FALSE(FALSE), the eNodeB cannot configure this candidate SCell as an SCell for CA UEs in a blind manner. The eNodeB must deliver the A4 measurement configurations related to the operating frequency of the cell to CA UEs before the eNodeB can configure the cell as an SCell.

Indicates the measurement period for automatic grouping for MLB. If the number of samples collected in the first period meets the requirement, the eNodeB calculates the coverage overlap proportion and sets or clears overlap indicators within the period. If the number of samples collected in the first period does not meet the requirement, the eNodeB extends a second period and performs accumulated statistics collection. To ensure the work efficiency of the algorithm, the eNodeB extends only one period for sample counting. A shorter measurement period results in faster setting or clearing of overlap indicators. A longer measurement period results in the opposite effect.It is recommended that this parameter be set to a multiple of 5. If this parameter is not set to a multiple of 5, the actually effective parameter value is extended to a multiple of 5.
