    Set RNC-Oriented FRC Algorithm Parameters(SET UFRC)

    Function

    Use this command to set the RNC-Oriented Fundamental Resource Configuration (FRC) parameters.

    The FRC function includes two aspects:

    - Allocation of channel type and bandwidth based on service requests.

    - Configuration of channel parameters based on the Quality of Service (QoS) requirements.

    Note

    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.

    idle mode)

    Impact on Network Performance: None

    PwrCtrlAlg Power control algorithm

    selectionMeaning: This parameter specifies how the UE interprets the received

    Transmit Power Control (TPC) commands, that is, selecting a UL

    inner-loop power control algorithm. Two different algorithms (denoted

    ALGORITHM1 and ALGORITHM2) are available, related to this

    parameter. When the parameter is set to ALGORITHM1, the UE

    adjusts the uplink t ransmit power once every timeslot. When the

    parameter is set to ALGORITHM2, the UE adjusts the uplink transmitpower once every five timeslots. For details, see 3GPP TS 25.214.

    DpcMode DL power control mode Meaning: DL power control mode.

    - SINGLE_TPC, a fast power control mode, indicates that a unique

    TPC command is sent in each timeslot on the DPCCH.

    - TPC_TRIPLET_IN_SOFT, a slow power control mode, indicates that

    the same TPC command is sent over three timeslots. It is applicableto soft handover, and it can decrease the power deviation.

    - TPC_AUTO_ADJUST, an automatic adjustment mode, indicates that

    the value of DPC_MODE can be modified by sending the ACTIVE SET

    UPDATE message to the UE.

    For details, see 3GPP TS 25.214.

    GUI Value Range: SINGLE_TPC, TPC_TRIPLET_IN_SOFT,

    TPC_AUTO_ADJUST

    Unit: None

    Actual Value Range: SINGLE_TPC, TPC_TRIPLET_IN_SOFT,

    Impact on Network Performance: None

    TfciPo TFCI power offset Meaning: Transmit power offset of TFCI bits to data bits in every

    timeslot for a downlink DPCCH frame. For details about this

    parameter, see 3GPP TS 25.214.

    GUI Value Range: 0~24

    Unit: 0.25dB

    Actual Value Range: 0~6

    MML Default Value: None

    Recommended Value: 0

    Parameter Relationship: NoneService 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 TFCI bits. The small

    parameter value also causes TFCI bit demodulation performance to

    deteriorate, decreases downlink UE throughput, and affects downlink

    cell capacity. Occasionally, the small parameter value lowers the

    downlink DPDCH transmit power. The larger the value of this

    parameter, the higher the transmit power of TFCI bits. The large

    parameter value also wastes downlink power resources and affects

    downlink cell capacity.

    TpcPo TPC power offset Meaning: Transmit power offset of TPC bits to data bits in every

    timeslot for a downlink DPCCH frame. For details about thisparameter, see 3GPP TS 25.214.

    GUI Value Range: 0~24

    Unit: 0.25dB

  • 7/28/2019 Set RNC-Oriented FRC Algorithm Parameters(SET UFRC)

    3/16

    Recommended Value: 12

    Parameter Relationship: None

    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.

    PilotPo Pilot power offset Meaning: Transmit power offset of pilot bits to data bits in every

    timeslot for a downlink DPCCH frame. For details about this

    parameter, see 3GPP TS 25.214.

    GUI Value Range: 0~24

    Unit: 0.25dB

    Actual Value Range: 0~6

    MML Default Value: None

    Recommended Value: 12

    Parameter Relationship: None

    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.

    DefPosFixedorFlex DL DPCH

    PosFixedorFlex Cfg by

    default

    Meaning: Multiplexing method of a downlink dedicated physical

    channel. When this parameter is set to FIXED, each transport channel

    has a fixed start position in the CCTrCH. When this parameter is set

    to FLEX, each transport channel's start position in the CCTrCH can

    change. All transport channels' data is next to each other but some

    room can be spared at the end of the CCTrCH. For details, see 3GPPTS 25.212.

    GUI Value Range: FIXED, FLEX

    Unit: None

    Actual Value Range: FIXED, FLEX

    MML Default Value: None

    Recommended Value: FLEX

    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 FIXED, UEs

    can conveniently perform blind rate detection. If this parameter is set

    to FLEX, limited OVSF code resources are saved.

    DlSaveCodeResourceSwitch DL AMR-NB Code-

    Resource-Saving switchMeaning: This parameter specifies whether the DL code-resource-

    saving mode is applicable to narrowband AMR services, ON specifies

    the DL code-resource-saving mode is applicable to narrowband AMR

    services, OFF specifies the DL code-resource-saving mode is not

    applicable. In code-resource-saving mode, SF256 is used if the DL

    maximum bit rate of single AMR service is lower than or equal to 7.95

    kbit/s, while SF128 is used if the code-resource-saving mode is not

    applied.

    GUI Value Range: ON, OFF

    Unit: None

    Actual Value Range: OFF, ON

    MML Default Value: None

    Recommended Value: ON

    Parameter Relationship: The code-resource-saving mode is applicable

    to narrowband AMR services only when this 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

    DlDpchPlSaveMode DL DPCH puncturing

    limit in the saving modeMeaning: This parameter specifies the puncturing limit used in the

    spreading factor calculation algorithm for DL DPCH in code-resource-

    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.

    GUI Value Range: 3~9

    Unit: None

    Actual Value Range: 3~9

    MML Default Value: None

    Recommended Value: 6

    Parameter Relationship: None

    Service Interrupted After Modification : No (No impact on the UE inidle mode)

    Impact on Network Performance: None

    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.

    Impact on Network Performance: None

    EDpdchPlnonMax Value of PLnon-max Meaning: Value of PLnon-max used when UEs choose an uplink E-

    DPDCH SF and the UEs' data is carried over the E-DCH. For detailsabout this parameter, see 3GPP TS 25.212.

    GUI Value Range: 11~25

    Unit: None

    Actual Value Range: 0.44~1, step: 0.04

    MML Default Value: None

    Recommended Value: 11

    Parameter Relationship: None

    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 higher the HSUPA transport block puncture rate, the

    larger SF of these transport blocks, and the less the consumed CEs.

    With the high puncture rate, code gains are small, power efficiency islow, and HSUPA cell throughput is low. The larger the value of this

    parameter: the lower the HSUPA transport block puncture rate, the

    smaller SF of these transport blocks, and the more the consumed

    CEs. Worse still, the puncture rate decreases to 0. With the low

    puncture rate, code gains are large, power efficiency is high, and

    HSUPA cell throughput is high.

    EDpcchPoFor2msTTI E-DPCCH power offset

    for 2ms TTIMeaning: Power offset of an uplink E-DPCCH to an uplink DPCCH for

    2 ms TTI UEs. For details about this parameter, see 3GPP TS

    25.214.

    GUI Value Range: PO_5/15, PO_6/15, PO_8/15, PO_9/15,

    MML Default Value: None

    Recommended Value: PO_15/15

    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

    small value, the E-DPCCH receive power of 2 ms TTI UEs is very low,

    E-DPCCH demodulation and uplink transmission performance

    deteriorate, and uplink cell throughput and user experience are

    affected. If this parameter is set to a very large value, the E-DPCCH

    receive power of 2 ms TTI UEs is very high but E-DPCCH

    demodulation performance is satisfactory. However, this wastes uplink

    power resources and as a result affects uplink cell capacity.

    EDpcchPoFor10msTTI E-DPCCH power offset

    for 10ms TTIMeaning: Power offset of an uplink E-DPCCH to an uplink DPCCH for

    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.

    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.

    Parameter Relationship: None

    Service Interrupted After Modification : No (No impact on the UE in

    deteriorates transmission performance.
