-Maximum power for all downlink channels added together, that is allowed to be used in a cell

-The target value of the total transmitted power (PtxTarget) can be exceeded by the value of this parameter before the cell is considered to be overloaded in downlink. Radio Access Bearer is not admitted, if the total transmitted power exceeds the sum of the values of this parameter and the PtxTarget. PtxOffset is used to calculate the first downlink overload threshold for BTS and RNC: PtxTargetBTS = PtxTarget+PrxOffset.

-This parameter defines the HS-PDSCH code set. If the HSDPA dynamic code allocation functionality cannot be used or it is deactivated, the code set contains just one

code amount (5). If the HSDPA dynamic code allocation functionality can be used and it is activated, the code set contains more than one code amounts

-The target for received total wideband interference power in a cell. An uplink RT RAB is not admitted if the estimated non-controllable power exceeds this threshold. PrxTarget is also used to calculate PrxTargetBTS, which is the first overload threshold for BSUL interference. The value of the PrxTarget is relative to the system noise; it gives an upper threshold for the noise

-This parameter defines the maximum downlink user bit rate allowed in a cell for an NRT PS domain RAB.

Parameter defines the target scheduling threshold for HSDPA power allocation. It is applicable to the HSDPA static resource allocation in RNC and ignored in the case of HSDPA dynamic resource allocation. Depending on the setting of the parameter HSDPAPriority, either the total transmitted carrier power or the total non-controllable transmitted power has to be below or equal to PtxTargetHSDPA before the first HS-DSCH MAC-d flow can be allocated in the cell. If at least one HS-DSCH MAC-d flow is allocated in the cell, PtxTargetHSDPA is used instead of PtxTarget as a target of PtxnonHSDPA in NRT DCH scheduling. If HSDPA static resource allocation is active, value of the parameter PtxMaxHSDPA added with the value of the

parameter PtxTargetHSDPA must not exceed the cell maximum transmission power defined by the minimum of the following parameters: PtxCellMax and MaxDLPowerCapability. Otherwise This parameter defines the maximum allowed target level for DCH packet scheduling when one or more MAC-d flows is set up in the cell. The target level is determined by the dynamically adjusted PtxTargetPS when HSDPA dynamic resource allocation is used in the cell.

Parameter defines the maximum allowed HSDPA transmission power.

Defines the noise level in the BTS digital receiver when there is no load (thermal noise + noise figure). This parameter is needed in noise rise calculations.

This parameter defines how measurement values should be filtered before Node B reports the common measurement of the received total wideband power in a cell to the RNC.The default value 2 means that both an old filtered measurement and a new measurement have the weight of 50%. This is an appropriate default value when the measurement period is 100 ms and the reporting period 200 ms (two measurements to be filtered). A high value of this parameter emphasises the old filtered measurement result. A low value emphasises the new measurement result. With value 0, old measurements are not considered. This parameter concerns 3GPP-specified NBAP-interface only.

Parameter is applicable to the HSDPA static resource allocation.The target value of the transmitted non-HSDPA power (PtxTargetHSDPA) can be exceeded by the value of this parameter before the cell is considered to be overloaded in the downlink. If the averaged PtxNonHSDPA exceeds or equals PtxTargetHSDPA + PtxOffsetHSDPA, depending on the setting of the parameter HSDPAPriority, overload control actions targeted either to HS-DSCH MAC-d flows or NRT DCHs are started.

This parameter defines the adjustment period - in terms of PtxTotal/PtxNonHSPA reporting periods - of the target level for DCH packet scheduling (PtxTargetPS) when one or more MAC-d flows is/are set up in the cell when HSDPA dynamic resource allocation is used in the cell.

Conditions to adjust PtxTargetPS are checked every nth received measurement report from the BTS, where n is defined by this parameter.

The target value of the total received power (PrxTarget) can be exceeded by the value of this parameter before the cell is considered to be overloaded in uplink. Radio Access Bearer is not admitted if the total received power exceeds the sum of the values of this parameter and the PrxTarget. PrxOffset is used to calculate the first uplink overload threshold for BTS and RNC:

PrxTargetBTS = PrxTarget+PrxOffset.

This parameter defines how measurement values should be filtered before Node B reports the common measurement of the received total transmitted carrier power in a cell to the RNC.

Used by UE functions for intra-frequency measurement reporting (in CELL_DCH).

Threshold used for addition-window in evaluation criteria for event type 1a.

Addition Window determines the relative threshold (A_Win) used by the UE to calculate the reporting range of event 1A. The threshold is either relative to the CPICH Ec/No measurement result of the best active set cell (M_best), or to the sum of active set measurement results (M_sum), depending on the value of the parameter Active Set Weighting Coefficient (W). When the CPICH Ec/No measurement result of a monitored cell (M_new) enters the reporting range, the UE transmits a Measurement Report to the RNC in order to add the monitored cell into the active set: M_new >= W * M_sum + ( 1 - W )* M_best - A_Win

Weight factor to include active set cells other than the best in evaluation criteria for event 1a.

Active Set Weighting Coefficient (W) is used to weight either the measurement result of the best active set cell (M_best) or the sum of measurement results of all active set cells (M_sum) when the UE calculates the reporting range for the events 1A (cell addition) and 1B (dropping of cell). The formula is: W * M_sum + ( 1 - W )* M_best

-13

Time in milliseconds (ms) between detection of event 1a and sending of the measurement report.

When a monitored cell enters the reporting range (addition window), the cell must continuously stay within the reporting range for a given period of time before the UE can send a Measurement Report to the RNC in order to add the cell into the active set (event 1A). The length of this period is controlled by the parameter Addition Time

Interval of event-triggered periodical reporting in case of 'cell addition failure' or 'cell replacement failure'. Indicates the interval in seconds (s) of periodical reporting
