C.2 Examples of the methodology

Tools: ARFCN - Frequency Conversion for 5G NR/LTE/UMTS/GSM

From figure C.2-1 it can be seen that there are two "Pre-defined configuration sets with different value tags".

The start position of Set1 is "1" with a list of 7 pre-defined configurations {1, 2, 3, 4, 5, 6, 7}.

The start position of Set2 is "10" with a list of 6 pre-defined configurations {10, 11, 12, 13, 14, 15}.

The "Pre-defined configurations list with variable size" has a start position of 0, and includes all of the pre-defined configurations not included in the sets {0, 8, 9}. The value tag at position 9 is not stored. This does not need to be explicitly indicated in the coding as "not stored" because there are no stored pre-defined configurations positioned after this in the list.

Figure C.2-1: Example scenario where non-stored pre-defined configurations do not need to be explicitly indicated

Figure C.2-2 is similar to Figure C.2-1. However in this case for the "Pre-defined configurations list with variable size", the pre-defined configuration in position 8 is not stored. This needs to be explicitly indicated in the coding as "not stored" because there is a stored pre-defined configuration (position 9) positioned after this in the list.

Annex D (Normative):
Implementation of Domain Specific Access Control (DSAC) in UEs of 3GPP Release 5

UEs of 3GPP Release 5 implementing the domain specific access class control feature but not implementing the network sharing feature shall act on the domain specific access class restriction indicated by the IE "Domain Specific Access Restriction Parameters For PLMN Of MIB" if present, and otherwise apply the access restrictions indicated by the IE "Cell Access Restriction".

Annex E (Normative):
EUTRA Feature group indicators

This annex contains the definitions of the bits in EUTRA Feature Group Indicators.

In this release of the specification the UE shall include the optional EUTRA Feature Group Indicators IE in the UE multi-mode/multi RAT capability IE of the RRC message. For a specific indicator, if all functionalities for a feature group listed in Table E.1 have been implemented and tested, the UE shall set the indicator as as "true" (as one), else (i.e., if any one of the functionalities in a feature group listed in Table E.1 have not been implemented or tested), the UE shall set the indicator as "false" (as zero).

The UE shall set all indicators that correspond to RATs not supported by the UE as "false" (as zero).

The UE shall set all indicators, which do not have a definition in Table E.1, as "false" (as zero).

If the optional EUTRA Feature Group Indicators IE is not included by a UE of a future release, the network may assume that all features pertaining to the RATs supported by the UE, listed in Table E.1 and deployed in the network, have been implemented and tested by the UE.

Table E.1: Defintions of feature group indicators

Index of indicator (bit number)	Definition (description of the supported functionality, if indicator set to ‘true’)	Notes
1 (leftmost bit)	– UTRA CELL_PCH to EUTRA RRC_IDLE cell reselection – UTRA URA_PCH to EUTRA RRC_IDLE cell reselection	UE supporting E-UTRAN shall set this bit to ‘TRUE’ in this version of specification.
2	EUTRAN measurements and reporting in connected mode	UE supporting E-UTRAN shall set this bit to ‘TRUE’ in this version of specification.
3	– UTRA CELL_FACH absolute priority cell reselection for high priority layers	UE supporting E-UTRAN shall set this bit to ‘TRUE’ in this version of specification.
4	– UTRA CELL_FACH absolute priority cell reselection for all layers	UE supporting E-UTRAN shall set this bit to ‘TRUE’ in this version of specification.

Clarification for mobility to EUTRAN

For mobility to E-UTRAN, it is assumed that we have 9 main "functions":

A. Support of measurements and cell reselection procedure in idle mode

B. Support of measurements and cell reselection procedure in CELL/URA_PCH

C. Support of RRC release with redirection procedure

D. Support of RRC reject with redirection procedure

E. Support of EUTRAN measurements and reporting in connected mode

F. Support of handover procedure in connected mode

G. Support of high priority layer measurements and cell reselection procedure in CELL_FACH

H. Support of all priority layer measurements and cell reselection procedure in CELL_FACH

I. Support of E-UTRA measurement for CELL_FACH for E-UTRA FDD and E-UTRA TDD

Of the above, all UEs that indicate support of E-UTRA in UE capability signalling "Support of E-UTRA FDD" or "Support of E-UTRA TDD" support A), C) and D) for all EUTRA bands they support.

For B) above, UEs indicates support by the Group 1 indicator bit (if Group 1 is set to "true", it is supported for all EUTRA bands the UE supports).

For E) above, UEs indicate support by the Group 2 indicator bit (if Group 2 is set to "true", it is supported for all EUTRA bands the UE supports). The compressed mode capability for supported E-UTRA frequency bands (‘Need for compressed mode’) in “Measurement capability extension” is ignored by the network when Group 2 is set to "false". In this version of the specification, the UE supporting E-UTRAN shall set the Group 2 indicator bit to "true".

For F) above, UEs indicate support by the separate UE capability signaling "Support of Inter-RAT PS Handover to E-UTRA FDD/TDD" defined in TS 25.306 (if this bit is set to "true", PS handover is supported for all EUTRA bands the UE supports). This bit can only be set to "true" if the UE has set the Group 2 indicator bit to "true".

For G) above, UEs indicates support by the Group 3 indicator bit (if Group 3 is set to "true", it is supported for all EUTRA bands the UE supports). If the separate UE capability "Support for absolute priority based cell re-selection in UTRAN" is also set to "true", UEs indicate support of high priority layer measurements and cell reselection procedure in CELL_FACH also for UTRA inter-frequency.

For H) above, UEs indicates support by the Group 4 indicator bit (if Group 4 is set to "true", it is supported for all EUTRA bands the UE supports). If the separate UE capability "Support for absolute priority based cell re-selection in UTRAN" is also set to "true", UEs indicate support of all priority layer measurements and cell reselection procedure in CELL_FACH also for UTRA inter-frequency. UEs that indicate support for H also indicate support for G.

For I) above, UEs indicate support by the separate UE capability signaling "Support of E-UTRA FDD measurements and reporting in CELL_FACH" and "Support of E-UTRA TDD measurements and reporting in CELL_FACH" defined in TS 25.306 (if the corresponding bit is set to "true", E-UTRA measurement for CELL_FACH for E-UTRA FDD and E-UTRA TDD is supported for all EUTRA FDD and TDD bands respectively, that the UE supports).

Annex F (Normative):
Support of Multiple Frequency Band Indicators (Multiple FBI) in UE

For UEs of 3GPP Release 9 or earlier, implementation of the multiple frequency band indicators feature is optional if the UE supports a band which has overlap with other bands defined in 3GPP [85], otherwise not applicable. Note that these other bands may not be supported by the UE, but the UE shall understand the UARFCN signalling for all bands, that overlap with the bands supported by the UE, and that are defined in the earliest version of [21] that includes all UE supported band(s).

For UEs of 3GPP from Release 10, implementation of the multiple frequency band indicators feature is mandatory if the UE supports a band which has overlap with other bands defined in 3GPP [85], otherwise not applicable. Note that these other bands may not be supported by the UE, but the UE shall understand the UARFCN signalling for all bands, that overlap with the bands supported by the UE, and that are defined in the earliest version of [21] that includes all UE supported bands.
