System Module rel.2 HSPA schedulers do not anymore consume R99 CE licenses (except A-DCH and SRB resources if needed)

In case when additional CCCH resources are required (e.g. extended cell case) R99 CE licenses capacity is decreased by amount of additional Rel99 CE required for CCCH processing

There are three types of HSDPA BTS processing set licenses from 1 to 3

Customers can put freely set 1 licenses or set 2 and set 3 licenses for increasing licensed HSDPA throughput and maximum HSDPA user amount HSDPA BTS processing set licenses are incremental as R99 CE licenses. Note: HSDPA processing set 1 licenses are always included into sets 2 and 3. E.g. when set 2 is bought maximum capacity is as set 2 defines (set 1 capacity is not summed into set 2)

Each HSDPA BTS processing set has certain capacity of users and HSDPA throughput

Processing set does not guarantee the maximum user amount and throughput but additional features are needed e.g. 64-QAM, 10/15 HS-PDSCH codes, 72HSPA users per cellHSDPA BTS processing set# Nokia Siemens Networks RU30 BaseBand dimensioning rulesCompany Confidential10Only shared scheduler license is not used in RU30 anymoreLicensing aspects (5/8)HSDPA BTS processing setHSDPA processing setMax number of HSDPA users per BTSMax HSDPA throughput per BTSHSDPA BTS processing set 1327,2 MbpsHSDPA BTS processing set 27221 MbpsHSDPA BTS processing set 37284 MbpsOperator can activate combination of different HSDPA processing sets

Total HSDPA licensed throughput is distributed among the available HSDPA schedulers. When the maximum licensed HSDPA throughput per scheduler is calculated, it is divided between HSDPA schedulers proportionally to "Maximum Throughput per HSDPA commissioned values (HSDPA Throughput Step) If there are only HSDPA Processing Set 1 licenses present in BTS, the division of licensed throughput will be done for each scheduler according to the following formula:

Scheduler_licensed_throughput = Round_down { Number_of_HSDPA_Processing_Sets * ( Scheduler_HSDPA_throughput_step / Total_number_of_HSDPA_throughput_step_per_BTS) } * 7,2 Mbps

If there are only HSDPA Processing Set 2 and 3 licenses present in BTS, the division of licensed throughput will be done for each scheduler according to the following formula:

Scheduler_licensed_throughput = Round_down { Number_of_HSDPA_Processing_Sets_ 2 + 4 * Number_of_HSDPA_Processing_Sets_ 3) * ( Scheduler_HSDPA_throughput_step / Total_number_of_HSDPA_throughput_step_per_BTS) } * 21 Mbps

HSDPA throughput:# Nokia Siemens Networks RU30 BaseBand dimensioning rulesCompany ConfidentialIf after calculations presented above throughput for all schedulers is lower than alllicensed throughput in the BTS, the remaining throughput is distributed with the samegranularity, (7.2Mbps or 21Mbps depending on available HSDPA BTS Processing Sets)prioritizing schedulers in the following order:a) scheduler with licensed throughput below commissioned throughputb) scheduler with lowest licensed throughputc) System Module rel.2 scheduler (FSM1 is prioritized over FSM2)48HSDPA BTS Processing Set resources allocation Total licensed HSDPA users is controlled on BTS level and it can be divided between LCGs according to commissioned shares.

Commissioning share option (HSDPA user share) defines the guaranteed HSDPA user capacity for each LCG. If commissioning is not done then user amount will be equally divided between LCGs.

For example:In case when 1 HSDPA BTS processing set 3 license was bought. It means that available user amount is 72 users. One LCG is created, it means that all amount of user can be taken. In case when 1 HSDPA BTS processing set 3 license was bought and two LCGs were configured. Operator can commission for example 20% of all available users to LCG1 and 40% to LCG2 and this mean that remaining 40% is common for both LCGs and can be shared freely between them.In case when no commissioning is done, whole available amount of users is divided equally per each configured LCG.

The maximum baseband resources that can be allocated for HSUPA are described by HSUPA BTS processing sets.

Baseband resources allocated for HSUPA purpose can change dynamically, based on current need (number of active users and combined L1 throughput of all HSUPA users) HSUPA baseband resource allocation is performed on step basis

Up to two HSUPA resource steps can be statistically commissioned for HSUPA
