RU30 LicenseBackground HSDPA and HSUPA schedulers (SM rel.2) do not consume CE licenses

HSDPA/HSUPA will have own capacity licenses.

RU30 Licenses are defined asHSDPA Processing SetHSUPA Processing SetR99 CE

RU30 LicenseConcept System Module Rel.2 consists of certain number of processing subunits

(SU , 1SU = 48 R99 CE). Each SM Rel.2 contains CCCH processing resources required for ‘Basic

Configurations’ (6 cells/10km or 3cells/20km). No additional CE needed.

System allocates the SU according to the License information. SU for HSDPA is dedicated only for HSDPA. SU for HSUPA and R99 can be overlapped and shared among each other.

HSDPA Dimensioning

Up to 2 HSDPA schedulers are supported with one SM Rel.2

Max. number of Active Users per HSDPA scheduler

Max number of cells assign to HSDPA scheduler Max scheduler throughput

240 6 252 Mbps

HSDPA processing set Max number of HSDPA users Max HSDPA throughput

HSDPA BTS processing set 1 32 7,2 Mbps

HSDPA BTS processing set 2 72 21 Mbps

HSDPA BTS processing set 3 72 84 Mbps

* PS1 would be overwrite by PS2 and PS3

HSDPA throughput provided by scheduler depends on: Activated features Number and type of BTS processing sets (# users and throughput) HSDPA throughput commissioning (BB resources allocation)

In RU30 there is only one type of HSDPA scheduler with SM Rel.2


Agenda

HSUPA DimensioningIn RU30 there is only one type of HSUPA scheduler with SM Rel.2

HSUPA processing set Max number of HSUPA users Max HSUPA throughput

HSUPA BTS processing set 1 24 5.8 Mbps

1 HSUPA Processing Set allows to reach 5.8Mbps or 24 users

HSUPA baseband resources allocation is performed in steps – so called HSUPA resource steps. One step is equal to ¼ of System Module rel.2 subunit.

HSUPA baseband capacity reservation is based on HSUPA license (HSUPA BTS processing sets)

In case if R99 CE licensed baseband resources are overlapping HSUPA licensed baseband resources – overlapped resources can be dynamically exchanged between R99 and HSUPA users

One HSUPA BTS processing set license corresponds to 6 HSUPA resource steps (1.5 subunit)

HSUPA Dimensioning In RU30EP1 with System Module Rel.2, one HSUPA scheduler can support up to 200

HSUPA users from 1 to 12 cells. (up to 240 HSUPA user in RU30EP2)

Up to one HSUPA scheduler is allocated per single LCG with single System Module Rel.2

Up to two HSUPA schedulers are allocated per single LCG with two System Modules rel.2 and frequency layers mapping to HW (note that frequency mapping to HW is possible only in one LCG scenario (RU30EP1/EP2)) up to 400 HSUPA users supported per LCG (2 x System Module rel.2)

Agenda

Tcell grouping

Group 2: Tcell values 3, 4 and 5Group 4: Tcell value 9

Group 1: Tcell values 0, 1 and 2 Group 3: Tcell values 6, 7 and 8

• Tcell grouping is used to group cells to the HSDPA scheduler

• Tcell groups 1 and 3 are handled by the first scheduler in System Module Rel.2 and Tcell groups 2 and 4 are handled by the second scheduler in System Module Rel.2.

• The same Tcell values can be used by different cells if those are allocated to different frequency layers.

• With Dual Cell HSDPA feature both cells from one sector must have the same Tcell value. Note that with the dual cell feature, two cells from the same sector need to be served by the same scheduler and belong to the same LCG.

• One scheduler can handle up to two Tcell groups. If there is only one Tcell group used, six cells can be supported. If there are two Tcell groups and one scheduler, up to three cells per Tcell group can be supported (still up to six cells are supported totally).

• Maximum four Tcell groups per LCG are possible

• The principles of grouping are as follows:

Scheduler 1

Agenda

LCG• In RU30 single LCG covers up to 12 cells with pure Release 2 HW configuration (System

Module + RF module). Up to four LCGs can be created in pure Rel. 2 HW configuration

• In case of at least one HW Rel.1 (System Module or RF module) up to two LCGs can be created each containing max 6 cells

• With pure HW rel.2 it is possible to use flexible BB pooling (LCG baseband capacity is assigned (commissioned) by % The percentage division is rounded to one subunit.

M5006 WBTS R99 HW - LCG

From WN7.0 onwards M5001 counters are not anymore updated for FlexiBTS Rel2 but new measurement type “M5006 WBTS R99 HW Resource” replaces it.

• The reason for this change is that Rel2 has separate licensing for channel types Rel99 / CSoHSPA / HSxPA.

• In case mixed Rel2 and Rel1 HW these M5001 counters are still reported for Rel1 HW

Rel99 CE capacity counters are available with M5006 • M5006 WBTS R99 HW measurement table include counters for WBTS R99 HW resource measurements• M5006C0..C38

M5008 - WBTS Level monitoringM5008 WBTS level monitoring is RU30 new measurement • M5008C0..M5008C35• Can be used to monitor

• HSPA throughput and users• Count complete BB usage (R99 + HSUPA) and then subcounters

showing R99 CE’s only • HSPA processing set utilisation• Licensed Capacity (HSPA users & throughput)• Report used # of HSUPA processing sets
