HSPA Key features - AMC Channel Quality Feedback (CQI)
Good CQI
nUE measures channel quality (SNR or Ec/Nt) and reports to Node B every 2ms or longer time.
Bad CQI
High Code Effective Rate
Low Code Effective Rate
nNodeB chooses modulation scheme, transport block size and code effective rate based on CQI. The test UE is cat12, the peak throughput is 1600kbps Good coverage
Bad coverage
AMC could improve radio bandwidth and fit for high speed radio transmission. HUAWEI TECHNOLOGIES Co., Ltd.

Strategy Recommendation for Mature Phase The new traffic features for this phase is that total UMTS users will growth and proportion of HSPA will increase!
Disadvantage n Investment for HSPA will be increased for HSPA application on two frequency; n HSPA User experience will be affected by R99 user pre-emptying resource;
Advantage n Take full advantage of network resource completely including spectrum and power; n The HSPA cell capacity can reach maximum and provide higher capacity;
n Load balance configuration will require more experience and optimization; n Complicated and advanced RRM algorithm is required.
n HSPA KPI will be promoted for accessibility and mobility; n Load reshuffle between two frequency will balance DL load;

What is the Point? –Initial Phase Inter-freq Handover is the most difficult for HSPA mobility optimization. HSPA Handover Type
HO Success Ratio
The performance of Intrafreq HSPA service cell change is based on the R99 intra-freq soft/softer handover.
H<->H Soft/Softer HO H<->D Intra-freq HO H<->H Inter-freq HO H<->D Inter-freq HO
HSPA shall cover hot spot area at initial phase on dedicated carrier, so there is too much inter-freq HSPA handover between hot-spot area and non hot-spot area.
H<->GPRS Inter-freq HO H<->H intra-freq Hard HO H<->D intra-freq Hard HO
Intra-freq hard handover is not suggested on commercial network.

HSPA and GPRS Handover is applied at the edge of UMTS coverage area.
Page 40
HSPA Optimization in HO area Coverage quality of HO area decide the DL throughput for mobile HSPA user. The higher Load will not impact the pilot pollution but will be deteriorated in coverage quality of handover area. The poor CQI will be reported if the Ec/Io is very bad, DL throughput is close relative to CQI in HO area, so the optimization for coverage in HO area is the key for mobile HSPA user.
This is the typical example for HSPA throughput optimization in dense urban. The average throughput of Application layer reach to 1.2Mbps.(Cat12 UE)

Question and Answer What is the feature of HSPA? AMC, Scheduler, lots of UE category, system resource allocation
What is most important before HSPA planning? HSPA deployment strategy including coverage target, dedicated carrier, service, etc.
What is the important input for HSPA coverage planning? Cell edge throughput
What factor will impact HSPA throughput? Environment condition, HSPA allowed load, CE/Iub resource. Huawei has advanced algorithm to improve the utilization efficiency.
What is highlight of Huawei HSPA CE consume? High efficient CE for large HSPA throughput, on CE requirement for softer handover, no CE requirement for CCH; CE allocate dynamically for HSUPA; all cell in one NodeB can share CE resource. HUAWEI TECHNOLOGIES Co., Ltd.

HSPA Key features - AMC Channel Quality Feedback (CQI)
Good CQI
nUE measures channel quality (SNR or Ec/Nt) and reports to Node B every 2ms or longer time.
Bad CQI
High Code Effective Rate
Low Code Effective Rate
nNodeB chooses modulation scheme, transport block size and code effective rate based on CQI. The test UE is cat12, the peak throughput is 1600kbps Good coverage
Bad coverage

Strategy Recommendation for Mature Phase The new traffic features for this phase is that total UMTS users will growth and proportion of HSPA will increase!
Disadvantage n Investment for HSPA will be increased for HSPA application on two frequency; n HSPA User experience will be affected by R99 user pre-emptying resource;
Advantage n Take full advantage of network resource completely including spectrum and power; n The HSPA cell capacity can reach maximum and provide higher capacity;
n Load balance configuration will require more experience and optimization; n Complicated and advanced RRM algorithm is required.
n HSPA KPI will be promoted for accessibility and mobility; n Load reshuffle between two frequency will balance DL load;

DRD access procedure works at multi-carrier same coverage scenario as showed before
DCH(HO) -> HSPA
n Pre-empty and Queue Pre-empty and Queue procedure works when high service users accessing, which have higher priority to allocate resource than normal user.

What is the Point? –Initial Phase Inter-freq Handover is the most difficult for HSPA mobility optimization. HSPA Handover Type
HO Success Ratio
The performance of Intrafreq HSPA service cell change is based on the R99 intra-freq soft/softer handover.
H<->H Soft/Softer HO H<->D Intra-freq HO H<->H Inter-freq HO H<->D Inter-freq HO
HSPA shall cover hot spot area at initial phase on dedicated carrier, so there is too much inter-freq HSPA handover between hot-spot area and non hot-spot area.
H<->GPRS Inter-freq HO H<->H intra-freq Hard HO H<->D intra-freq Hard HO
Intra-freq hard handover is not suggested on commercial network.

HSPA and GPRS Handover is applied at the edge of UMTS coverage area.

HSPA Optimization in HO area Coverage quality of HO area decide the DL throughput for mobile HSPA user. The higher Load will not impact the pilot pollution but will be deteriorated in coverage quality of handover area. The poor CQI will be reported if the Ec/Io is very bad, DL throughput is close relative to CQI in HO area, so the optimization for coverage in HO area is the key for mobile HSPA user.
This is the typical example for HSPA throughput optimization in dense urban. The average throughput of Application layer reach to 1.2Mbps.(Cat12 UE)

Question and Answer What is the feature of HSPA? AMC, Scheduler, lots of UE category, system resource allocation
What is most important before HSPA planning? HSPA deployment strategy including coverage target, dedicated carrier, service, etc.
What is the important input for HSPA coverage planning? Cell edge throughput
What factor will impact HSPA throughput? Environment condition, HSPA allowed load, CE/Iub resource. Huawei has advanced algorithm to improve the utilization efficiency.
What is highlight of Huawei HSPA CE consume? High efficient CE for large HSPA throughput, on CE requirement for softer handover, no CE requirement for CCH; CE allocate dynamically for HSUPA; all cell in one NodeB can share CE resource. HUAWEI TECHNOLOGIES Co., Ltd.
