Annex G (informative):
Signalling of Multiple Frequency Band Indicators (Multiple
FBI)
This annex contains a Stage 2 description of the mapping between the respective Multiple Frequency Band Indicators
(MFBI) lists and the:
- Frequency Band signalled in System Information Block type 5, System Information Block type 5bis and System
Information Block type 6
- UARFCN’s signalled in System Information Block type 11, System Information Block type 11bis and System
Information Block type 12
- EARFCN’s and extended EARFCN’s signalled in System Information Block type 19
G.1 Mapping between "Frequency band indicator", "Frequency
band indicator 2" or "Frequency band indicator 3" and
"Multiple Frequency Info list"
In System Information Block type 5, System Information Block type 5bis and System Information Block type 6 a single
UTRA Frequency Band may be broadcast in one of the IE’s "Frequency band indicator", "Frequency band indicator 2"
or "Frequency band indicator 3". This UTRA Frequency band can then have up to 8 additional overlapping UTRA
Frequency bands broadcast in the IE "Multiple Frequency Band indicator list".
G.2 Mapping between "New Inter-frequency cells" and "Multiple
Frequency Info List FDD"
In System Information Block type 11, System Information Block type 11bis and System Information Block type 12 a
list of up to 32 inter-frequency UTRA cells may be broadcast in the IE "New Inter-frequency cells". Additionally, for
up to 8 of the UARFCN broadcast in the IE "New Inter-frequency cells" there can be up to 8 additional overlapping
UTRA Frequency bands broadcast in the IE "Multiple Frequency Info List FDD".
The following criteria regarding the signalling of the Inter-frequency cells in SIB11/11bis should be considered:
- The "Frequency info" IE should appear only once in "New Inter-frequency cells" for each UARFCN i.e. for the
first Inter-frequency neighbour cell using that UARFCN. For each subsequent Inter-frequency neighbour cell
having the same UARFCN, the "Frequency info" should not be included, but rather the Mandatory Default (MD)
value will be used.
- All Inter-frequency neighbour cells having the same UARFCN should be listed contiguously within the IE "New
Inter-frequency cells" in SIB11/11bis.
- Each occurrence of the IE "Frequency info" included in the IE "New Inter-frequency cells" will have one
corresponding entry in "Multiple Frequency Info List FDD" i.e. the first "Frequency info" maps to the first entry
in "Multiple Frequency Info List FDD", the second "Frequency info" maps to the second entry in "Multiple
Frequency Info List FDD" and so on.
- If a specific instance of "Frequency info" included in the IE "New Inter-frequency cells" does not have any
overlapping band(s), the corresponding entry in "Multiple Frequency Info List FDD" should be empty.
Example:
The following inter-frequency UTRA cells are broadcast in System Information Block type 11
- Cell1 (UARFCN A)
- Cell2 (UARFCN A)
- Cell3 (UARFCN B)
