Li censi ng aspect s (1/ 3)General inf ormat ion

In RU30 for Flexi System Module Rel.2 CE licenses are valid for R99 traffic

HSDPA and HSUPA schedulers (System Module rel.2) do not consume CE licenses

HSDPA/HSUPA will have own capacity licenses that are called respectively HSDPA BTS processing sets 'andHSUPA BTS processing set

HSUPA and HSDPA schedulers located at System Module rel.1 (FSMB) still requires CE licenses

HW i n RU30 Flex i WCDMA BTSSyst em Module Rel.2 capacit y - number of subunit s

System Module Rel.2 traffic capacity depends on number of commissioned cells. Table below

presents number of available subunits for traffic use (or CCCH / interference cancellationprocessing)

Available resources (subunits) can be used for CCCH processing, HSDPA users, thr. and cells processing, HSUPA

users and thr. processing, R99 users processing and interference cancellation processing

Please note that each SM Rel.2 contains CCCH processing resources required for Basic Configurations (e.g. 6

cells/10km or 3cells/20km) included in the System Module rel.2 capacity

Tcel l gr oupi ngGeneral inf ormat ion

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 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).

The principles of grouping (maximum four TCell groups per LCG are possible) are as follows:

HSUPA license is called HSUPA BTS Processing Set

The HSUPA BTS Processing Set is a HSUPA BB resources reservation inside the Flexi System Module Rel.2, that

allows for a certain number of HSUPA users and HSUPA throughput.

HSUPA baseband resources allocation is performed in steps so called HSUPA resource steps. One step is equal

to of subunit.

In order to reach simultaneously certain number of HSUPA users and certain combined

L1 throughput , the following formula should be used to calculate required number ofHSUPA BTS Processing Sets

Number of HSUPA BTS Processing Sets = max ( HSUPA subunits / 1,5 ; Minimum amount of HSUPA BTS Processing

Sets )

Minimum amount of HSUPA BTS Processing Sets =

max ( Roundup ( Number_of_HSUPA_users / 24) ; Roundup(HSUPA_throughput / 5,8) )
