7 Parameters

Table 7-1 Parameter description

MO Parameter ID MML Command Featu

re ID Feature

Meaning:Indicates the switches used to enable or disable power control for PDSCH, PDCCH, and PHICH.

PdschSpsPcSwitch: Indicates the switch for power control during semi-persistent scheduling on the PDSCH. If the switch is turned off, power is allocated evenly during semi-persistent scheduling on the PDSCH.

If the switch is turned on, power control is applied during semi-persistent scheduling on the PDSCH, ensuring communication quality (indicated by IBLER) of VoIP services in the QPSK modulation scheme.

PhichInnerLoopPcSwitch: Indicates the switch for PHICH inner-loop power control.

If the switch is turned off, only the initial transmit power for the PHICH is set. If the switch is turned on, the eNodeB controls the physical channel transmit power to enable the receive SINR to converge to the target SINR.

PdcchPcSwitch: Indicates the switch for PDCCH power control. If the switch is turned off, power is allocated evenly to PDCCH. If the switch is turned on, power allocated to PDCCH is adjusted

dynamically.

GUI Value Range:PdschSpsPcSwitch, PhichInnerLoopPcSwitch, PdcchPcSwitch Unit:None

Actual Value Range:PdschSpsPcSwitch, PhichInnerLoopPcSwitch, PdcchPcSwitch Default Value:PdschSpsPcSwitch:Off, PhichInnerLoopPcSwitch:Off,

h DlSchSwitch MOD

CELLALGOSWIT

Meaning:Indicates the switches related to DL scheduling in the cell.

FreqSelSwitch: Indicates whether to

MO Parameter ID MML Command Featu

enable or disable frequency selection and scheduling. If this switch is turned on, data is transmitted on the frequency band with good-quality channels.

ServiceDiffSwitch: Indicates whether to enable or disable service differentiation. If this switch is turned on, service

differentiation is available. If this switch is turned off, service differentiation is unavailable.

SpsSchSwitch: Indicates whether to enable or disable semi-persistent scheduling during talk spurts of VoIP services. If this switch is turned on, semi-persistent scheduling is applied. If this switch is turned off, dynamic scheduling is applied.

MBSFNShutDownSwitch: Indicates whether to enable or disable Multimedia Broadcast Single Frequency Network (MBSFN) subframe shutdown. If this switch is turned on, MBSFN subframe shutdown is available. If this switch is turned off, MBSFN subframe shutdown is unavailable.

This switch is valid only when symbol-based power amplifier (PA) shutdown is enabled. If the MBSFN subframe shutdown switch is valid, the switch for the mapping from SIBs to SI messages becomes invalid. If the MBSFN subframe shutdown switch is invalid, the switch for the mapping from SIBs to SI messages becomes valid.

MBSFN subframe shutdown applies only to single-mode eNodeBs.

GUI Value Range:OFF(Off), ON(On) Unit:None

Actual Value Range:OFF, ON Default Value:OFF(Off)

Meaning:Indicates the switches used to enable or disable power control for PUSCH and PUCCH.

CloseLoopSpsSwitch: If this switch is turned off, closed-loop power control is not performed for PUSCH in semi-persistent scheduling mode. If this switch is turned on, TPC commands are adjusted based on correctness of the initially received data packet to decrease the IBLER.

InnerLoopPuschSwitch: If this switch is turned off, inner-loop power control is not performed for PUSCH in dynamic

scheduling mode. If this switch is turned on, inner-loop power control is performed for PUSCH in dynamic scheduling mode.

PhSinrTarUpdateSwitch is the switch used

MO Parameter ID MML Command Featu

re ID Feature

Name Description

to enable or disable PH-based SINR target updates in dynamic scheduling mode. This switch will be removed in the later

versions. In this version, the setting of this switch is still synchronized between the M2000 and the eNodeB, but it is no longer used internally. Therefore, avoid using this switch. This function is incorporated into inner-loop power control for PUSCH in dynamic scheduling mode. Therefore, to enable this function, set

InnerLoopPuschSwitch to On.

InnerLoopPucchSwitch: If this switch is turned off, inner-loop power control is not performed for PUCCH. If this switch is turned on, inner-loop power control is performed for PUCCH.

OiSinrTarUpdateSwitch: This switch will be removed in the later versions. In this version, the setting of this switch is still synchronized between the M2000 and the eNodeB, but it is no longer used internally.

Therefore, avoid using this switch. This function is incorporated into inner-loop power control for PUSCH in dynamic scheduling mode. Therefore, to enable this function, set InnerLoopPuschSwitch to On.

PowerSavingSwitch: This switch will be removed in the later versions. In this version, the setting of this switch is still synchronized between the M2000 and the eNodeB, but it is no longer used internally.

Therefore, avoid using this switch.

MO Parameter ID MML Command Featu

Meaning:Indicates the switches related to uplink (UL) scheduling in the cell. The switches are used to enable or disable specific UL scheduling functions.

SpsSchSwitch: Indicates whether to enable or disable semi-persistent scheduling during talk spurts of VoIP services. If this switch is turned on, semi-persistent scheduling is applied. If this switch is turned off, dynamic scheduling is applied.

SinrAdjustSwitch: Indicates whether to adjust the measured SINR based on ACK/NACK messages in a UL HARQ process.

PreAllocationSwitch: Indicates whether to enable or disable preallocation, which shortens end-to-end service delays when the UL load is light. Preallocation reduces the probability of UEs entering DRX and therefore shortens the service time of the UEs.

UlVmimoSwitch: Indicates whether to enable or disable UL MIMO. If UL MU-MIMO is enabled, the eNodeB selects UEs for pairing according to pairing rules. Then, the pair of UEs transmits data using the same frequency-time resources, increasing system throughput and spectral efficiency.

TtiBundlingSwitch: Indicates whether to enable or disable TTI bundling. If TTI bundling is enabled, more transmission opportunities are available to UEs within the delay budget for VoIP services on the air interface, thereby improving uplink coverage.

ImIcSwitch: Indicates whether to enable or

MO Parameter ID MML Command Featu

disable intermodulation (IM) component elimination for UEs. When data is transmitted in both UL and DL, two IM components are generated symmetrically beside the Direct Current (DC) subcarrier on the DL receive channel due to

interference from UL radio signals. If this switch is turned on, IM component elimination is performed on UEs. If this switch is turned off, IM component elimination is not performed on UEs. This switch applies only to FDD cells working in band 20.

Actual Value Range:SpsSchSwitch, SinrAdjustSwitch, PreAllocationSwitch,
