Action 1 . HSDPA radio resource allocation strategies
SET MACHSPARA: LOCELL=0, RSCALLOCM=POWERCODE_BAL
This feature can balance the consumption of currently available code resources and power resources, to
avoid code or power unilaterally congestion in order to improve resource utilization, enhance cell capacity.
Relative to the code priority, the power code balance can enhance the cell downlink load, while reducing
the resource utilization of code.
Action 2. Configuring CQI Adjustment Based on Dynamic BLER Target
SET MACHSPARA: LOCELL=0, CQIADJALGOFNONCON=CQI_ADJ_BY_DYN_BLER;
With this feature, the NodeB can dynamically select the optimum BLER target value based on the channel
quality fluctuation of HSDPA users. The NodeB then adjusts the Channel Quality Indicator (CQI)
accordingly, improving user throughput and cell throughput.
Action 3. Modify Cell HSDPA Parameters (Recommended value of Power Compensate is set to 1~1.5)
MOD UCELLHSDPA : CellId=0, HsPdschMPOConstEnum = 0;
This parameter named Measure Power Offset Constant is used to compute measurement power offset.
Measurement power offset is used by UE to obtain total received HS-PDSCH power. The calculation for
Measure Power Offset is as shown below:
Measure Power Offset = Max(-6, Min(13,CellMaxPower - PcpichPower - Measure Power OffsetConstant)).
For details of the IE "Measure Power Offset", refer to 3GPP TS 25.214.

The HSDPA throughput has a steady improvement after swap in the last 30 days.
The average HSDPA throughput reach the target 1776 bps.
