SRAN baseband

FBBA/C bb capacity = 6 subunits

FBBC usage in WCDMA FSMF + 2x FBBA

• 6 x OBSAI interface for Radio Modules

FSMF + 2x FBBC

• 8 x OBSAI interface for Radio Modules • 1 x OBSAI cable needed between FSMF and each FBBC

FBBA and FBBC have exactly same baseband capacity i.e. 6 subunits for traffic use • FBBC has 4 x OBSAI ports for Radio Modules in front panel, compared to 1 x OBSAI port in FBBA • For WCDMA 1 x OBSAI cable would be needed between FSMF and FBBC if more than one dedicated WCDMA RF units connected to FBBC  each FBBC adds only one OBSAI port more in configuration compared to FBBA • RF connectivity need comes in multi-RAT sites and RF sharing cases which are typical SRAN cases FBBC will be supported in WCDMA in SRAN 16. Both in WCDMA dedicated mode and in Multi-RAT mode

There are three LTE baseband SW allocation types, depending on LTE radio configuration (supported bandwidth / # cells / features): • Reduced Cell Set (RCS) • Basic Cell Set (BCS)

• Extended Cell Set (ECS) Each configuration affects BB allocation (-> amount of FSMF/FBBC cards) Reduced cell set (RCS)

SRAN baseband SBTS baseband resources sharing - Summary • System Module sharing functionality allows to share single BTS baseband resources between different RATs (i.e. GSM / WCDMA / LTE). •

SBTS supports also single RAT scenarios.

•

RAT baseband dimensioning rules remain unchanged as such.

•

SBTS supported configuration can be found in the following excel file describing SBTS profiles.
