None
Parameters
Parameter ID Parameter Name Parameter Description
DefaultConstantValue Default Constant Value Meaning: Constant that is used by the RNC to calculate the
DPCCH_Power_Offset which is further used by the UE to calculate
the UL DPCCH_Initial_Power.
The formulas are as follows:
DPCCH_Power_Offset = Primary CPICH DL TX power + UL
interference + Default Constant Value
Here, DPCCH_Power_Offset is the DPCCH initial transmit (TX) poweroffset, Primary CPICH DL TX power is the downlink TX power of the P-
CPICH.
DPCCH_Initial_Power = DPCCH_Power_offset - CPICH_RSCP
Here, CPICH_RSCP is the received signal code power of the P-CPICH
measured by the UE.
A small value of DPCCH_Power_Offset might lead to uplink
synchronization failure at cell edges during link setup, thus affecting
the uplink coverage. A large value of DPCCH_Power_Offset, however,
has instantaneous interference on uplink reception, thus affecting the
uplink reception performance. For details, see 3GPP TS 25.331.

Service Interrupted After Modification : No (No impact on the UE in
idle mode)
Impact on Network Performance: The smaller the value of this
parameter, the lower the transmit power of TPC bits. The small
parameter value also increases the possibility that TPC bits are
incorrectly interpreted. In such a case, it is difficult to control UEs'
transmit power, affecting uplink transmission performance. The larger
the value of this parameter, the higher the transmit power of TPC bits.
The large parameter value also wastes downlink power resources and
affects downlink cell capacity.

Service Interrupted After Modification : No (No impact on the UE in
idle mode)
Impact on Network Performance: The smaller the value of thisparameter: the lower the transmit power of pilot bits, the less accurate
of the SIR assessment on the UE side, the greater the downlink
DPCCH transmit power fluctuation, and the higher the downlink
DPDCH mean power. The small parameter value also affects downlink
cell capacity. The larger the value of this parameter, the higher the
transmit power of pilot bits. The large parameter value also wastes
downlink power resources and affects downlink cell capacity.

saving mode.
GUI Value Range: 10~25
Unit: None
Actual Value Range: 0.4~1, step: 0.04
MML Default Value: None
Recommended Value: 11
Parameter Relationship: This parameter is valid only when the code-resource-saving mode is applicable to narrowband AMR services, that
is, when the DlSaveCodeResourceSwitch parameter is set to ON
and the AllowedSaveCodeResource parameter is set to TRUE
through the ADD UCELLFRC command.
Service Interrupted After Modification : No (No impact on the UE in
idle mode)
Impact on Network Performance: None
DrxCycleLenCoef Paging DRX cycle
coefficientMeaning: UTRAN-specific Discontinuous Reception (DRX) cycle
length coefficient. In connected mode, the UE uses the shorter one
between CN-specific DRX cycle length coefficient and UTRAN-specific
DRX cycle length coefficient. In idle mode, the UE can use the DRX
mode to receive paging indications so as to reduce power
consumption; in this case, the UE needs to monitor only one pagingindication in one paging occasion during each DRX cycle.
A value too small causes the UE to check the paging channel
frequently, thus having great power consumption. A value too large
makes the response of the UE to the paging slow and the core
network repeatedly page the UE, thus increasing the downlink
interference.

UlBeTraffInitBitrate UL BE traffic Initial bit
rateMeaning: UL initial access rate of PS background or interactive
service. When DCCC function is enabled, the uplink initial access rate
will be set to this value if the uplink maximum rate is higher than the
initial access rate. A higher value indicates that it takes shorter time
for BE services to reach the maximum rate. Note that the rate will be
decreased through negotiation when congestion occurs. A smaller
value indicates that BE services is easier to be accessed. It is not
recommended to set a too small value, because it will take longer
time for BE services to adjust to a higher rate when needed.

DeltaT2tp Traffic to Total Pilot
Power OffsetMeaning: Offset of all traffic channels' power to power of the DPCCH
and E-DPCCH. This parameter value is used to calculate the E-
DPCCH transmit power when a UE transmits data with the E-DPCCH
Boosting function. For details about this parameter, see 3GPP TS
25.213.
GUI Value Range: PO_10, PO_11, PO_12, PO_13, PO_14, PO_15,
PO_16
Unit: dB
Actual Value Range: 10, 11, 12, 13, 14, 15, 16
MML Default Value: None
Recommended Value: PO_12
Parameter Relationship: NoneService Interrupted After Modification : No (No impact on the UE in
idle mode)
Impact on Network Performance: If this parameter is set to a very
large value, E-DPCCH transmit power is very low. As a result, multi-
path searching and channel estimation are affected, and the required
E-DPCCH transmit power increases. This decreases uplink cell
capacity. If this parameter is set to a very small value, E-DPCCH
transmit power is high, wasting power resources and decreasing
uplink cell capacity.
EcBoostingTotalRateThd The total rate threshold
of HSUPA traffic for
Boosting
Meaning: Total data rate threshold for an E-DPCCH Boosting-enabled
UE. If the selected E-TFCI of an E-DPCCH Boosting-enabled UE
exceeds the E-TFCIec,boosting specific to E-DPCCH Boosting, the
UE sends uplink data using E-DPCCH Boosting. Note that this E-
TFCIec,boosting is related to the E-TFCI corresponding to the
maximum transport block that does not exceed this threshold.

15/16
Recommended Value: 10
Parameter Relationship: None
Service Interrupted After Modification : No (No impact on the UE in
idle mode)
Impact on Network Performance: If this parameter is set to a very
large value, only a small number of UEs can use E-DPCCH Boosting.
In addition, the resource utilization of E-DPCCH Boosting is low and
the cell throughput cannot greatly increase. If this parameter is set to
a very small value, a large number of UEs preempt limited resources
of E-DPCCH Boosting. For UEs without such resources, the uplink
transmission performance deteriorates and as a result uplink cell
capacity decreases.
DCMIMOMacHsWinSize DCMIMOMacHsWinSize Meaning: Size of the reception window for the MAC-ehs when DC-
HSDPA and MIMO are enabled. On the UE side, only PDUs in the
reception window for the MAC-ehs are reordered.
GUI Value Range: D4, D6, D8, D12, D16, D24, D32, D64, D128

Service Interrupted After Modification : No (No impact on the UE in
idle mode)Impact on Network Performance: The larger the value of this
parameter is: the more UE memory is occupied and the lower the
probability that data is discarded. The smaller the value of this
parameter is, the higher the probability that data is discarded. This
deteriorates transmission performance.
