Hello, Ahmed_Aldolaimy93.
Provide the following information for your reference.
CqiAdjAlgoSwitch: Indicates whether to allow the eNodeB to adjust the UE-reported CQI based on the initial block error rate (IBLER). If this option is selected, the CQI adjustment algorithm is enabled. In this case, the eNodeB adjusts the UE-reported CQI based on the IBLER. If this option is deselected, the CQI adjustment algorithm is disabled. In this case, the eNodeB does not adjust the UE-reported CQI based on the IBLER. This option applies only to LTE FDD and LTE TDD. StepVarySwitch: Indicates whether to enable variable-step-based adjustment. If this option is selected, variable-step-based adjustment is enabled to accelerate the convergence of IBLER. In this case, rapid adjustment at large steps is applied if there is a large difference between the measured IBLER and target IBLER; fine-tuning at small steps is applied if the measured IBLER is close to the target IBLER. If this option is deselected, the adjustment is performed at a fixed step. This option applies only to LTE FDD and LTE TDD. DlVarIBLERtargetSwitch: Indicates whether to enable downlink target IBLER adaptation. If this option is selected, the downlink target IBLER is adaptively adjusted based on the TBS to improve spectral efficiency. If this option is deselected, the target IBLER is determined based on the setting of the DlEnVarIblerTargetSwitch option of this parameter. This option applies only to LTE FDD and LTE TDD. TddBundlingCqiAdjOptSwitch: Indicates whether to enable optimized CQI adjustment in ACK bundling mode. If this option is selected, optimized CQI adjustment is enabled. If this option is deselected, optimized CQI adjustment is disabled. This option applies only to LTE TDD. TddMultiplexingCqiAdjOptSwitch: Indicates whether to enable optimized CQI adjustment in ACK multiplexing mode. If this option is selected, optimized CQI adjustment is enabled. If this option is deselected, optimized CQI adjustment is disabled. This option applies only to LTE TDD. AdaptiveStepVarySwitch: Indicates whether to enable adaptive step change in CQI adjustment. This option applies only to LTE FDD and LTE TDD. If this option is selected, the CQI adjustment is performed at a large step when significant changes in the signal quality are detected, accelerating the IBLER convergence. If this option is deselected, the CQI adjustment is performed at a fixed step. DlCqiAdjDeltaOptSwitch: Indicates whether to optimize CQI adjustment value calculation. If this option is deselected, the CQI adjustment value is calculated using the following formula: CQI adjustment value = (Number of ACKs for initial transmissions x CQI adjustment value per ACK + Number of NACKs for initial transmissions x CQI adjustment value per NACK)/(Number of NACKs for initial transmissions + Number of ACKs for initial transmissions). If this option is selected, the CQI adjustment value is calculated using the following formula: CQI adjustment value = Number of ACKs for initial transmissions x CQI adjustment value per ACK + Number of NACKs for initial transmissions x CQI adjustment value per NACK. This option applies only to LTE FDD and LTE TDD. DlEnVarIblerTargetSwitch: Indicates whether to enable enhanced downlink target IBLER adaptation. If this option is selected, the downlink target IBLER is adaptively adjusted based on CQI fluctuation and TBS. If this option is deselected, the downlink target IBLER policy is controlled by the DlVarIBLERtargetSwitch option of this parameter. This option applies only to LTE FDD and LTE TDD. DlRetxTbsIndexAdjOptSwitch: Indicates whether to optimize transport block size (TBS) index adjustment in retransmissions. If this option is selected, TBS index adjustment in retransmissions is optimized. The TBS index is lowered for the scheduling of the last two retransmissions, and the TBS index is determined based on the CQI adjustment result for the scheduling of other retransmissions. If this option is deselected, TBS index adjustment in retransmissions is not optimized. The TBS index is determined based on the CQI adjustment result for the scheduling of all retransmissions. This option applies only to LTE FDD and LTE TDD. CfiConvertOptSwitch: Indicates whether to optimize CFI conversion. If this option is selected, new CFI calculation tables for normal and special subframes are used to ensure more accurate MCS selection in normal and special subframes and facilitate IBLER convergence to the target value. If this option is deselected, the original CFI calculation tables for normal and special subframes are used. This option applies only to LTE TDD. BundlingOptThdSwitch: Indicates whether to adjust the MCS index threshold for enabling the optimized CQI adjustment algorithm in TDD bundling mode. If this option is selected, the lower MCS index threshold for enabling the optimized CQI adjustment algorithm in TDD bundling mode is changed from MCS index 6 to MCS index 0. If this option is deselected, the lower MCS index threshold for enabling the optimized CQI adjustment algorithm in TDD bundling mode is MCS index 6. This option applies only to LTE TDD. DlSpsMcsIncreaseSwitch: Indicates whether to enable MCS index increase for semi-persistent scheduling (SPS). If this option is selected, MCS index increase is enabled for SPS, reducing the number of RBs for SPS and improving cell performance when RB resources are limited. However, the VoLTE MOS value may decrease. If this option is deselected, MCS index increase is disabled for SPS, increasing the VoLTE MOS value. However, more RBs may be consumed for SPS. This option applies only to LTE FDD and LTE TDD. CqiAdjTimeEffSwitch: Indicates whether to enable validity evaluation and adjustment for CQI adjustment values, and whether to trigger large-step-based CQI adjustment when a long time has elapsed before a UE begins to perform services based on the setting of the AdaptiveStepVarySwitch option of this parameter. If this option is selected, the eNodeB evaluates the validity of all CQI adjustment values in a unified manner and adjusts these adjustment values based on the evaluation results. If this option and the AdaptiveStepVarySwitch option are selected, large-step-based CQI adjustment is triggered when a long time has elapsed before a UE begins to perform services. If this option is deselected, the eNodeB does not evaluate the validity of CQI adjustment values or adjust these values in a unified manner, and large-step-based CQI adjustment is not triggered when a long time has elapsed before a UE begins to perform services. This option applies only to LTE TDD. RptCqiFltInitSwitch: Indicates whether to adjust the initial filtered value of the reported CQI. If this option is selected, the initial filtered value of the reported CQI is determined based on the CQI value reported by the UE, and the filtering coefficient for the reported CQI in the first several reporting periods is adjusted. If this option is deselected, the initial filtered value of CQIs reported by all UEs is fixed to 4. This option applies only to LTE TDD. UeSigInitCqiModSwitch: Indicates the time when the reported initial CQI takes effect. If this option is selected, the reported initial CQI takes effect when the ACK to Msg4 HARQ retransmission is received or when Msg5 is received. If this option is deselected, the reported CQI immediately takes effect. This option applies only to LTE TDD. CqiFastCompstSwitch: Indicates whether the eNodeB performs fast CQI compensation for the following UEs: UEs handed over to cells whose values of PCI modulo 3 conflict with source cells' values of PCI modulo 3, beamforming UEs in 8T8R cells, and UEs reporting aperiodic CQIs during network access under a high CAPS condition. If this option is selected, the eNodeB identifies these UEs and quickly compensates for their CQIs. If this option is deselected, the eNodeB does not identify these UEs for CQI compensation. This option applies only to LTE TDD. CfiConvertWiDrsSwitch: Indicates whether to consider the DMRS overhead when converting the control format indicator (CFI) for beamforming UEs. If this option is selected, the eNodeB considers the DMRS overhead when converting the CFI of beamforming UEs. If this option is deselected, the eNodeB does not consider the DMRS overhead when converting the CFI of beamforming UEs in open-loop TM7, TM8, or TM9 mode. This option applies only to LTE FDD and LTE TDD. IblerCqiOffsetSwitch: Indicates whether to perform CQI compensation based on the target IBLER. The eNodeB performs CQI compensation based on the target IBLER only if this option is selected. This option applies only to LTE TDD. CqiFltOptSwitch: Indicates whether to optimize CQI filtering. If this option is selected, the eNodeB determines whether to discard a UE-reported CQI based on this reported CQI and the previous HARQ retransmission IBLER, does not filter CQIs again in case of TM change, and triggers both large step increase and large step decrease during step adaptation. If this option is deselected, the eNodeB directly uses UE-reported CQIs, filters CQIs again in case of TM change, and triggers only large step increase during step adaptation. This option applies only to LTE TDD. PreciseMcsAdaptSwitch: Indicates whether to enable precise MCS adaptation. If this option is selected, the eNodeB selects the TBS with a higher index for the first downlink HARQ retransmission. In addition, when the initial CQI adjustment value is relatively conservative, the eNodeB increases and compensates for the CQI adjustment value. If this option is deselected, the eNodeB does not perform the preceding operations. This option applies only to LTE FDD. PilotOffCqiAdjOptSwitch: Indicates CQI adaptation optimization for CRS transmission disabling. If this option is selected, for UEs regarded as large-packet UEs when the BreathingPilotSwitch or EmimoCpsSwitch option is selected, the CQI adjustment is performed at a large step in case of significant signal quality changes. If this option is deselected, the CQI adjustment is performed at a fixed step for the preceding UEs. This option applies only to LTE FDD.
