This can be introduced by means of the Little ivalue, whichdescribes how much two cells overlap (bigger overlapping more inter-cell interferences)

The average UE transmit power is increased due to fast closed loop power control and fastfading

HSDPA Capacity G-Factor
The G Factor reflects the distance between the MS and BSantenna thus setting a value for G factor means makingassumptions on user location.
A typical range is from -5dB (Cell Edge) to 20dB Typical G factor distributions (CDF) coming from NSN
simulation tools as well as operator field experience are

HSDPA capacity and RAN features
HSDPA capacity is influenced by capabilities of the networkand the UE
Number of codes (5, 10, 15) Higher peak bit rate in good conditions
Higher cell throughputCode multiplexing (multiple 5 code UEs can utilise up to 15 codes)
Higher spectrum efficiency

HSUPA Capacity HSUPA Cell Throughput
Methodology
The uplink load is shared between HSUPA and R99 DCH uplink load
Uplink load is translated to uplink C/I using the uplink load equation
UEs distribution inside the cell impacts on possible C/I thus it also impacts on cell
throughput By default, each UE is allocated an equal share of UL Load.
The saving in uplink load is re-distributed to the UE closer to the cell
39 NSN Siemens Networks 3G Radio Planning Essentials / NPO Capability DevelopmentFor internal use
C/I = Eb/No Processing Gain
C/I is translated to HSUPA bit rate using the Eb/No

General information
HSUPA activation requires a "fixed pool" of 8 CE when activating thefeature.In RU10 this fixed activation is not needed
BTS Resource Manager can dynamically allocate additional BB resourcesfor HSUPA.
Depending on the total amount of free available CE (#licenses and installedHW capacity) and the traffic load,
A max. of 128 CE in UltraSite and 160 CE (RU10 = 240CEs) in Flexi BTScan be utilized by HSUPA.
72 NSN Siemens Networks 3G Radio Planning Essentials / NPO Capability Development
For internal use
In case of conflict with R99 RT or NRT traffic needs, BTS Resource managerwill reduce the amount of BB resources available for HSUPA.
HSUPA user can reach max 2.0 Mbps HSUPA is used only together with HSDPA for DL In addition to the CE consumption for HSDPA and HSUPA activation, 1
CE for signaling is required per user.

Number of HSUPA UE per BTS/LCG increased to 60 In RAS06 max 24 users per BTS (20 per cell)
Max 20 UE per cell also in RU10 Total BTS level throughput increased to 12.6 Mbps (8.4 Mbps in RAS06) See HSUPA resource steps and dimensioning tables in next slides

For internal use
Improved resource handling:
Resource Manager will reallocate free resources (relieved from Rel99) back to HSUPA. Improves user throughput In RAS06 only new HSUPA calls are allocated to relieved resources
HSUPA users can be moved between Flexi sub modules. Improves HSUPA user throughput as second submodule is taken earlier into use as in RAS06 In RAS06 HSUPA users can not be moved from one sub module to another

With one FSMD you can have up to 4 shared HSDPA schedulers with 15codes and 64 users/LCG
Still there is room for HSUPA and R99
With one FSMD you can also enable dedicated schedulers for 5 cells
With two FSMD you can share easily two operators RAN with high HSDPA
