Packet data modelling

Packet data traffic is a sum of multiple services with differenttraffic profiles and service quality requirements

Accurate modelling of packet data traffic requires multiple assumptions

and complex simulations

Practical packet data traffic model utilises average bit rate

Because of power rise in the UL load calculation, the little ishould be corrected (little iismultiplied by pw_riseparameter)

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


C/I = Eb/No Processing Gain

C/I is translated to HSUPA bit rate using the Eb/No

look-up table derived from link level simulations

Base band processing units general info

Base band units of Flexi and Ultra BTS product line:

Flexi WCDMA System Module (FSM)

Used in Flexi Node B

2 FSMs are allowed in maximum in the NodeBConsists of FSP cards (Functional Signal Processing unit)

CE (Channel Element) is basic processing capacity unit


Used in UltraSite and MetroSite NodeBMax No of WSPs per NodeB depends on its type (18 WSPs in maximum)

CE is basic processing capacity unit

Both base band units provide Rx and Tx channel processing (scramblingand descrambling, interleaving UL/DL, spreading and despreading, channelcoding and decoding)

Main changes compared to FSMB and FSMC/D


47/99


RU10 delivers new system modules FSMC and FSMD, whichare more efficient from the baseband allocation perspectivethan FSMB

Main enhancements via new rel.2 HWMaximum capacity is higher, with FSMD much higher (up to 792 CEs)R99 baseband allocation with 384 kbps is lowered from 16 to 12 CEs

HSDPA allocation is lower


Shared HSDPA scheduler for BB efficiency for FSMB 80 CE and forFSMC/D 72 CEs

Note: In RU10 shared HSDPA with FSMB enables 48 users/LCG and withFSMC/D 64 users/LCG

Dedicated HSDPA scheduler with 64 users/cell (1+1+1), FSMB 240 CEsand FSMC/D 216 CEs

HSUPA allocation is lower To meet the maximum number of users (60 users/LCG) FSMB =240 CEs

and FSMC/D 144 CEs

HSUPAGeneral information


72/99

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.


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.

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

FSMD enables very high usage of HSPA and leaving lots of capacity forR99

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
