6.2.3.1.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 36.304, clause 5.2.4.1, 5.2.4.2 and 5.2.4.5.

[TS 36.304, clause 5.2.4.1]

Absolute priorities of different E-UTRAN frequencies or inter-RAT frequencies may be provided to the UE in the system information, in the RRCConnectionRelease message, or by inheriting from another RAT at inter-RAT cell (re)selection. In the case of system information, an E-UTRAN frequency or inter-RAT frequency may be listed without providing a priority (i.e. the field cellReselectionPriority is absent for that frequency). If priorities are provided in dedicated signalling, the UE shall ignore all the priorities provided in system information. If UE is in camped on any cell state, UE shall only apply the priorities provided by system information from current cell, and the UE preserves priorities provided by dedicated signalling unless specified otherwise. When the UE in camped normally state, has only dedicated priorities other than for the current frequency, the UE shall consider the current frequency to be the lowest priority frequency (i.e. lower than the eight network configured values). The UE shall delete priorities provided by dedicated signalling when:

the UE enters RRC_CONNECTED state; or
the optional validity time of dedicated priorities (T320) expires; or
a PLMN selection is performed on request by NAS [5].

NOTE: Equal priorities between RATs are not supported.

The UE shall only perform cell reselection evaluation for E-UTRAN frequencies and inter-RAT frequencies that are given in system information and for which the UE has a priority provided.

The UE shall not consider any black listed cells as candidate for cell reselection.

The UE shall inherit the priorities provided by dedicated signalling and the remaining validity time (i.e., T320 in E-UTRA, T322 in UTRA and [T3230, FFS] in GERAN), if configured, at inter-RAT cell (re)selection.

NOTE: The network may assign dedicated cell reselection priorities for frequencies not configured by system information.

[TS 36.304, clause 5.2.4.2]

When evaluating for reselection purposes cell selection criterion or SnonServingCell,x, the UE shall use parameters provided by the serving cell.

Following rules are used by the UE to limit needed measurements:

– If S_intrasearch is sent in the serving cell and S_ServingCell> S_intrasearch, UE may choose to not perform intra-frequency measurements.

– If S_ServingCell<= S_intrasearch,or S_intrasearch is not sent in the serving cell UE shall perform intra-frequency measurements.

– The UE shall apply the following rules for E-UTRAN inter-frequencies and inter-RAT frequencies which are indicated in system information and for which the UE has priority provided as defined in 5.2.4.1:

– For an E-UTRAN inter-frequency or inter-RAT frequency with a reselection priority higher than the reselection priority of the current E-UTRA frequency the UE shall perform measurements of higher priority E-UTRAN inter-frequency or inter-RAT frequencies according to [10].

– For an E-UTRAN inter-frequency with an equal or lower reselection priority than the reselection priority of the current E-UTRA frequency and for inter-RAT frequency with lower reselection priority than the reselection priority of the current E-UTRAN frequency:

– If S_{nonintrasearch} is sent in the serving cell and S_ServingCell > S_{nonintrasearch} UE may choose not to perform measurements of E-UTRAN inter-frequencies or inter-RAT frequency cells of equal or lower priority.

– If S_ServingCell <= S_{nonintrasearch}or S_{nonintrasearch} is not sent in the serving cell the UE shall perform measurements of E-UTRAN inter-frequencies or inter-RAT frequency cells of equal or lower priority according to [10].

Where S_ServingCellis the Srxlev-value of the serving cell.

[TS 36.304, clause 5.2.4.5]

Criteria 1: the S_{nonServingCell,x} of a cell on evaluated frequency is greater than Thresh_{x, high} during a time interval Treselection_RAT;

Cell reselection to a cell on a higher priority E-UTRAN frequency or inter-RAT frequency than serving frequency shall be performed if:

– A cell of a higher priority E-UTRAN frequency or inter-RAT frequency fulfils criteria 1; and

more than 1 second has elapsed since the UE camped on the current serving cell.

Cell reselection to a cell on a lower priority E-UTRAN frequency or inter-RAT frequency than serving frequency shall be performed if:

– No cell on serving frequency or on an equal priority E-UTRAN frequency or on a higher priority E-UTRAN frequency or inter-RAT frequency than serving frequency fulfils the criteria 1; and

– S_ServingCell< Thresh_{serving, low} and the S_{nonServingCell,x} of a cell of a lower priority E-UTRAN frequency or inter-RAT frequency is greater than Thresh_{x, low}during a time interval Treselection_RAT; and

– more than 1 second has elapsed since the UE camped on the current serving cell.

or if:

– there are no candidate cells for reselection on serving frequency according to 5.2.4.4 or 5.3.1.

Cell reselection to a cell on an equal priority E-UTRAN frequency shall be based on ranking for Intra-frequency cell reselection as defined in sub-clause 5.2.4.6.

For GERAN, UTRAN, and E-UTRAN, S_{nonServingCell,x} is the Srxlev-value of an evaluated cell. For UTRAN FDD, Squal is higher than 0, as defined in [8]. For cdma2000 RATs, S_{nonServingCell,x} is equal to FLOOR(-2 x 10 x log10 Ec/Io) in units of 0.5 dB, as defined in [18], with Ec/Io referring to the value measured From the evaluated cell.

6.2.3.1a.2 Conformance requirements

References: The conformance requirements covered in the current TC are specified in: TS 36.304, clause 5.2.4.5.

[TS 36.304, clause 5.2.4.5]

If threshServingLowQ is provided in SystemInformationBlockType3, cell reselection to a cell on a higher priority E-UTRAN frequency or inter-RAT frequency than the serving frequency shall be performed if:

– A cell of a higher priority EUTRAN or UTRAN FDD RAT/ frequency fulfils Squal > Thresh_{X, HighQ} during a time interval Treselection_RAT; or

– A cell of a higher priority UTRAN TDD, GERAN or CDMA2000 RAT/ frequency fulfils Srxlev > Thresh_{X, HighP} during a time interval Treselection_RAT; and

More than 1 second has elapsed since the UE camped on the current serving cell.

Otherwise, cell reselection to a cell on a higher priority E-UTRAN frequency or inter-RAT frequency than the serving frequency shall be performed if:

– A cell of a higher priority RAT/ frequency fulfils Srxlev > Thresh_{X, HighP} during a time interval Treselection_RAT; and

More than 1 second has elapsed since the UE camped on the current serving cell.

Cell reselection to a cell on an equal priority E-UTRAN frequency shall be based on ranking for Intra-frequency cell reselection as defined in sub-clause 5.2.4.6.

If threshServingLowQ is provided in SystemInformationBlockType3, cell reselection to a cell on a lower priority E-UTRAN frequency or inter-RAT frequency than the serving frequency shall be performed if:

– The serving cell fulfils Squal < Thresh_{Serving, LowQ} and a cell of a lower priority EUTRAN or UTRAN FDD RAT/ frequency fulfils Squal > Thresh_{X, LowQ} during a time interval Treselection_RAT; or

– The serving cell fulfils Squal < Thresh_{Serving, LowQ} and a cell of a lower priority UTRAN TDD, GERAN or CDMA2000 RAT/ frequency fulfils Srxlev > Thresh_{X, LowP} during a time interval Treselection_RAT; and

– More than 1 second has elapsed since the UE camped on the current serving cell.

Cell reselection to a higher priority RAT/ frequency shall take precedence over a lower priority RAT/ frequency, if multiple cells of different priorities fulfil the cell reselection criteria.

For cdma2000 RATs, Srxlev is equal to -FLOOR(-2 x 10 x log10 Ec/Io) in units of 0.5 dB, as defined in [18], with Ec/Io referring to the value measured from the evaluated cell.

For cdma2000 RATs, Thresh_{X, HighP} and Thresh_{X, LowP} are equal to -1 times the values signalled for the corresponding parameters in the system information.

– If the highest-priority frequency is an E-UTRAN frequency, a cell ranked as the best cell among the cells on the highest priority frequency(ies) meeting the criteria according to section 5.2.4.6;

– If the highest-priority frequency is from another RAT, a cell ranked as the best cell among the cells on the highest priority frequency(ies) meeting the criteria of that RAT.

6.2.3.3.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 25.304, clause 5.2.6.1.2a and 5.2.6.1.4a.

[TS 25.304, clause 5.2.6.1.2a]

If the UE has received absolute priority information for inter-RAT layers, the UE shall follow these rules:

– The UE shall perform measurements of inter-RAT layers with a priority higher than the priority of the current serving cell.

NOTE: The rate of these measurements may vary depending on whether Srxlev and Squal of the serving cell are above or below S_{prioritysearch1} and S_{prioritysearch2}. This is specified in [10].

– For inter-RAT layers with a priority lower than the priority of the current serving cell:

– If Srxlev_ServingCell > S_{prioritysearch1} and Squal_ServingCell > S_{prioritysearch2} the UE may choose not to perform measurements of inter-RAT layers of lower priority.

– If Srxlev_ServingCell <= S_{prioritysearch1} or Squal_ServingCell <= S_{prioritysearch2} the UE shall perform measurements of inter-RAT layers of lower priority.

[TS 25.304, clause 5.2.6.1.4a]

Absolute priorities of different absolute priority layers may be provided to the UE. The following cell reselection criteria are used for inter-frequency cells if absolute priority information for inter-frequency is available to the UE, and inter-RAT cells if absolute priority information for inter-RAT is available to the UE.

…

The following definitions apply:

6.2.3.3a.1 Test Purpose (TP)

(1)

with { UE in UTRA_Idle state }

ensure that {

when { UE detects the cell re-selection criteria are met for the cell which belongs to the lower priority inter-RAT E-UTRA cell}

then { UE reselects the cell which belongs to the lower priority inter-RAT E-UTRA cell }

}

(2)

with { UE in UTRA_Idle state }

ensure that {

when { UE detects the cell re-selection criteria are met for the cell which belongs to the higher priority inter-RAT E-UTRA cell}

then { UE reselects the cell which belongs to the higher priority inter-RAT E-UTRA cell }

}

6.2.3.3a.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 25.304, clause 5.2.6.1.2a and 5.2.6.1.4a.

[TS 25.304, clause 5.2.6.1.2a]

If the UE has received absolute priority information for inter-RAT layers, the UE shall follow these rules:

– The UE shall perform measurements of inter-RAT layers with a priority higher than the priority of the current serving cell.

NOTE: The rate of these measurements may vary depending on whether Srxlev and Squal of the serving cell are above or below S_{prioritysearch1} and S_{prioritysearch2}. This is specified in [10].

– For inter-RAT layers with a priority lower than the priority of the current serving cell:

– If Srxlev_ServingCell > S_{prioritysearch1} and Squal_ServingCell > S_{prioritysearch2} the UE may choose not to perform measurements of inter-RAT layers of lower priority.

– If Srxlev_ServingCell <= S_{prioritysearch1} or Squal_ServingCell <= S_{prioritysearch2} the UE shall perform measurements of inter-RAT layers of lower priority.

[TS 25.304, clause 5.2.6.1.4a]

Absolute priorities of different absolute priority layers may be provided to the UE. The following cell reselection criteria are used for inter-frequency cells if absolute priority inform69ation for inter-frequency is available to the UE, and inter-RAT cells if absolute priority information for inter-RAT is available to the UE.

…

The following definitions apply for the layers for which Thresh_x,high2 or Thresh_x,low2 are not provided:

– Criterion 1: the Srxlev_{nonServingCell,x} of a cell on an evaluated higher absolute priority layer is greater than Thresh_x,high during a time interval Treselection;

…

– Criterion 3: (Srxlev_ServingCell < Thresh_serving,low or Squal_ServingCell <= 0) and the Srxlev_{nonServingCell,x} of a cell on an evaluated lower absolute priority layer is greater than Thresh_x,low during a time interval Treselection;

The following definitions apply for the layers for which both Thresh_x,high2 and Thresh_x,low2 are provided:

– Criterion 4: the Squal_{nonServingCell,x} of a cell on an evaluated higher absolute priority layer is greater than Thresh_x,high2 during a time interval Treselection;

– Criterion 5: (Squal_ServingCell < Thresh_serving,low2 or SrxlevServingCell <= 0) and the Squal_{nonServingCell,x} of a cell on an evaluated lower absolute priority layer is greater than Thresh_x,low2during a time interval Treselection;

Cell reselection to a cell on a higher absolute priority layer than the camped frequency shall be performed if criterion 1 or 4 is fulfilled.

…

Cell reselection to a cell on a lower absolute priority layer than the camped frequency shall be performed if criterion 3 or 5 is fulfilled.

If more than one cell meets the above criteria, the UE shall reselect the cell with the highest Srxlev_{nonServingCell,x} among the cells meeting the criteria on the highest absolute priority layer.

The UE shall not perform cell reselection to cells for which the cell selection criterion S is not fulfilled.

The UE shall not perform cell reselection until more than 1 second has elapsed since the UE camped on the current serving cell.

…

Cell reselection from UTRAN to E-UTRAN, for which Squal (RSRQ) based cell reselection parameters are broadcast in system information, shall be performed based on the Squal criteria (criterion 4 or 5) if the UE supports Squal based cell reselection from E-UTRAN to UTRAN. Otherwise, cell reselection to E-UTRAN shall be performed based on Srxlev criteria.

6.2.3.4 Inter-RAT Cell reselection / From UTRA_CELL_PCH state to E-UTRA RRC_IDLE

6.2.3.4.1 Test Purpose (TP)

(1)

with { UE in UTRA_CELL_PCH state }

ensure that {

when { UE detects the cell re-selection criteria are met for the cell which belongs to the higher priority inter-RAT E-UTRA cell}

then { UE reselects the cell which belongs to the higher priority inter-RAT E-UTRA cell }

}

6.2.3.4.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 25.304, clause 5.2.6.1.2a and 5.2.6.1.4a; TS 25.331, clause 8.3.9.2, 8.3.9.3, Annex E.

[TS 25.304, clause 5.2.6.1.2a]

The measurement rules below apply in Idle, URA_PCH, CELL_PCH states.

…

If the UE has received absolute priority information for inter-RAT layers, the UE shall follow these rules:

– The UE shall perform measurements of inter-RAT layers with a priority higher than the priority of the current serving cell.

NOTE: The rate of these measurements may vary depending on whether Srxlev and Squal of the serving cell are above or below S_{prioritysearch1} and S_{prioritysearch2}. This is specified in [10].

– For inter-RAT layers with a priority lower than the priority of the current serving cell:

– If Srxlev_ServingCell > S_{prioritysearch1} and Squal_ServingCell > S_{prioritysearch2} the UE may choose not to perform measurements of inter-RAT layers of lower priority.

– If Srxlev_ServingCell <= S_{prioritysearch1} or Squal_ServingCell <= S_{prioritysearch2} the UE shall perform measurements of inter-RAT layers of lower priority.

[TS 25.304, clause 5.2.6.1.4a]

…

The following definitions apply:

– Criterion 1: the Srxlev_{nonServingCell,x} of a cell on an evaluated higher absolute priority layer is greater than Thresh_x,high during a time interval Treselection;

…

Cell reselection to a cell on a higher absolute priority layer than the camped frequency shall be performed if criterion 1 is fulfilled.

…

If more than one cell meets the above criteria, the UE shall reselect the cell with the highest Srxlev_{nonServingCell,x} among the cells meeting the criteria on the highest absolute priority layer.

The UE shall not perform cell reselection to cells for which the cell selection criterion S is not fulfilled.

The UE shall not perform cell reselection until more than 1 second has elapsed since the UE camped on the current serving cell.

For UE in RRC connected mode states CELL_PCH or URA_PCH the interval Treselection_s,PCH applies, if provided in SIB4 (see [4]), while for UE in RRC connected mode state CELL_FACH the interval Treselection_s,FACH applies, if provided in SIB4 (see [4]).

In all the above criteria the values of Treselection_s, Treselection_s,PCH or Treselection_s,FACH apply for Treselection and are scaled according to the UE mobility state and target RAT, as specified in 5.2.6.1.1a.

[TS 25.331, 8.3.9.2]

This procedure is applicable in states CELL_FACH, CELL_PCH or URA_PCH. Inter-RAT cell reselection to E-UTRAN in CELL_FACH state is not supported in this version of the specification.

When the UE based on received system information makes a cell reselection to a radio access technology other than UTRAN, e.g. GSM/GPRS or E-UTRA, according to the criteria specified in [4], the UE shall:

…

[TS 25.331, 8.3.9.3]

When the UE has succeeded in reselecting a cell in the target radio access technology, the UE shall:

1> release all UTRAN specific resources.

UTRAN should:

1> release all UE dedicated resources upon indication that the UE has completed a connection establishment to the other radio access technology.

[TS 25.331, Annex E]

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 "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 zero.

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

If the optional EUTRA Feature Group Indicators IE is not included by a UE supporting a future release of the specification, the network may assume the UE supports all features in the feature groups listed in table E.1 and deployed in the network.

Table E.1: Definitions 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
2	EUTRAN measurements and reporting in connected mode
3	Undefined
4	Undefined

Clarification for mobility to EUTRAN

For mobility to E-UTRAN, it is assumed that we have 6 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

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) EUTRA bands.

For B) above, UEs indicate 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".

For F) above, UEs indicate support by the separate UE capability signalling "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".

6.2.3.5a.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 36.304, clause 5.2.4.2 and 5.2.4.5.

[TS 36.304, clause 5.2.4.2]

When evaluating Srxlev and Squal of non-serving cells for reselection purposes, the UE shall use parameters provided by the serving cell.

Following rules are used by the UE to limit needed measurements:

– If the serving cell fulfils Srxlev> S_IntraSearchP and Squal > S_IntraSearchQ, the UE may choose not to perform intra-frequency measurements.

– Otherwise, the UE shall perform intra-frequency measurements.

– If the serving cell fulfils Srxlev > S_{nonIntraSearchP} and Squal > S_{nonIntraSearchQ}, the UE may choose not to perform measurements of E-UTRAN inter-frequencies or inter-RAT frequency cells of equal or lower priority.

– Otherwise, the UE shall perform measurements of E-UTRAN inter-frequencies or inter-RAT frequency cells of equal or lower priority according to [10].

[TS 36.304, clause 5.2.4.5]

– A cell of a higher priority EUTRAN or UTRAN FDD RAT/ frequency fulfils Squal > Thresh_{X, HighQ} during a time interval Treselection_RAT; or

…

More than 1 second has elapsed since the UE camped on the current serving cell.

Otherwise, cell reselection to a cell on a higher priority E-UTRAN frequency or inter-RAT frequency than the serving frequency shall be performed if:

– A cell of a higher priority RAT/ frequency fulfils Srxlev > Thresh_{X, HighP} during a time interval Treselection_RAT; and

More than 1 second has elapsed since the UE camped on the current serving cell.

…

– More than 1 second has elapsed since the UE camped on the current serving cell.

Otherwise, cell reselection to a cell on a lower priority E-UTRAN frequency or inter-RAT frequency than the serving frequency shall be performed if:

– The serving cell fulfils Srxlev < Thresh_{Serving, LowP} and a cell of a lower priority RAT/ frequency fulfils Srxlev > Thresh_{X, LowP}during a time interval Treselection_RAT; and

– More than 1 second has elapsed since the UE camped on the current serving cell.

Cell reselection to a higher priority RAT/ frequency shall take precedence over a lower priority RAT/ frequency, if multiple cells of different priorities fulfil the cell reselection criteria.

…

Cell reselection to another RAT, for which Squal based cell reselection parameters are broadcast in system information, shall be performed based on the Squal criteria if the UE supports Squal (RSRQ) based cell reselection to E-UTRAN from all the other RATs provided by system information which UE supports. Otherwise, cell reselection to another RAT shall be performed based on Srxlev criteria.

6.2.3.6 Inter-RAT Cell reselection / From E-UTRA RRC_IDLE to UTRA_Idle according to RAT priority provided by dedicated signalling

6.2.3.6.1 Test Purpose (TP)

(1)

with { UE in E-UTRA RRC_IDLE state having received an RRCConnectionRelease message including a cellReselectionPriority }

ensure that {

when { UE detects the cell re-selection criteria are met for the cell which belongs to the higher priority RAT }

then { UE reselects the cell which belongs to the higher priority RAT }

}

(2)

with { UE in E-UTRA RRC_IDLE state having received an RRCConnectionRelease message including a cellReselectionPriority }

ensure that {

when { UE detects the cell re-selection criteria are met for the cell which belongs to the lower priority RAT }

then { UE reselects the cell which belongs to the lower priority RAT }

}

(3)

with { UE in E-UTRA RRC_IDLE state having received an RRCConnectionRelease message including a cellReselectionPriority }

ensure that {

when { T320 expires }

then { UE reselects a cell by applying the cellReselectionPriority broadcast in the system information }

}

(4)

with { UE in E-UTRA RRC_IDLE state, and reselection priorities have been provided in dedicated signalling }

ensure that {

when { T320 has not expired }

then { The UE shall ignore all the priorities provided in system information, and not perform cell reselection evaluation for E-UTRAN frequencies and inter-RAT frequencies for which the UE doesn’t have a priority provided }

}

6.2.3.6.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 36.304, clause 5.2.4.1 and 5.2.4.5 and TS 36.331, clause 5.3.8.3 and 5.3.8.4.

[TS 36.304, clause 5.2.4.1]

Absolute priorities of different E-UTRAN frequencies or inter-RAT frequencies may be provided to the UE in the system information, in the RRCConnectionRelease message, or by inheriting from another RAT at inter-RAT cell (re)selection. In the case of system information, an E-UTRAN frequency or inter-RAT frequency may be listed without providing a priority (i.e. the field cellReselectionPriority is absent for that frequency). If priorities are provided in dedicated signalling, the UE shall ignore all the priorities provided in system information. If UE is in camped on any cell state, UE shall only apply the priorities provided by system information from current cell, and the UE preserves priorities provided by dedicated signalling unless specified otherwise. When the UE in camped normally state, has only dedicated priorities other than for the current frequency, the UE shall consider the current frequency to be the lowest priority frequency (i.e. lower than the eight network configured values). While the UE is camped on a suitable CSG cell, the UE shall always consider the current frequency to be the highest priority frequency (i.e. higher than the eight network configured values), irrespective of any other priority value allocated to this frequency. The UE shall delete priorities provided by dedicated signalling when:

the UE enters RRC_CONNECTED state; or
the optional validity time of dedicated priorities (T320) expires; or
a PLMN selection is performed on request by NAS [5].

NOTE: Equal priorities between RATs are not supported.

The UE shall only perform cell reselection evaluation for E-UTRAN frequencies and inter-RAT frequencies that are given in system information and for which the UE has a priority provided.

The UE shall not consider any black listed cells as candidate for cell reselection.

The UE shall inherit the priorities provided by dedicated signalling and the remaining validity time (i.e., T320 in E-UTRA, T322 in UTRA and T3230 in GERAN), if configured, at inter-RAT cell (re)selection.

NOTE: The network may assign dedicated cell reselection priorities for frequencies not configured by system information.

[TS 36.304, clause 5.2.4.5]

Criteria 1: the S_{nonServingCell,x} of a cell on evaluated frequency is greater than Thresh_{x, high} during a time interval Treselection_RAT;

Cell reselection to a cell on a higher priority E-UTRAN frequency or inter-RAT frequency than serving frequency shall be performed if:

– A cell of a higher priority E-UTRAN frequency or inter-RAT frequency fulfils criteria 1; and

more than 1 second has elapsed since the UE camped on the current serving cell.

Cell reselection to a cell on an equal priority E-UTRAN frequency shall be based on ranking for Intra-frequency cell reselection as defined in sub-clause 5.2.4.6.

Cell reselection to a cell on a lower priority E-UTRAN frequency or inter-RAT frequency than serving frequency shall be performed if:

– No cell on a higher priority E-UTRAN frequency or inter-RAT frequency than serving frequency fulfills the criteria 1; and

– No cell on serving frequency or on an equal priority E-UTRAN frequency fulfils the criteria in 5.2.4.6; and

– more than 1 second has elapsed since the UE camped on the current serving cell.

…

For GERAN, UTRAN, and E-UTRAN, S_{nonServingCell,x} is the Srxlev-value of an evaluated cell. For UTRAN FDD, Squal is higher than 0, as defined in [8]. For cdma2000 RATs, S_{nonServingCell,x} is equal to -FLOOR(-2 x 10 x log10 Ec/Io) in units of 0.5 dB, as defined in [18], with Ec/Io referring to the value measured from the evaluated cell.

For cdma2000 RATs, Threshx, high and Threshx, low are equal to -1 times the values signalled for the corresponding parameters in the system information.

In all the above criteria the value of Treselection_RAT is scaled when the UE is in the medium or high mobility state as defined in subclause 5.2.4.3.1. If more than one cell meets the above criteria, the UE shall reselect a cell ranked as the best cell among the cells meeting the criteria on the highest priority frequencies or the highest priority RAT if the highest priority RAT is E-UTRA according to criteria defined in 5.2.4.6.

[TS 36.331, clause 5.3.8.3]

The UE shall:

1> delay the following actions defined in this sub-clause 60 ms from the moment the RRCConnectionRelease message was received or optionally when lower layers indicate that the receipt of the RRCConnectionRelease message has been successfully acknowledged, whichever is earlier;

1> if the RRCConnectionRelease message includes the idleModeMobilityControlInfo:

2> store the cell reselection priority information provided by the idleModeMobilityControlInfo;

2> if the t320 is included:

3> start timer T320, with the timer value set according to the value of t320;

1> else:

2> apply the cell reselection priority information broadcast in the system information;

1> if the releaseCause received in the RRCConnectionRelease message indicates ‘loadBalancingTAURequired‘:

2> perform the actions upon leaving RRC_CONNECTED as specified in 5.3.12, with release cause ‘load balancing TAU required’;

1> else:

2> perform the actions upon leaving RRC_CONNECTED as specified in 5.3.12, with release cause ‘other’;

[TS 36.331, clause 5.3.8.4]

The UE shall:

1> if T320 expires:

2> if stored, discard the cell reselection priority information provided by the idleModeMobilityControlInfo or inherited from another RAT;

2> apply the cell reselection priority information broadcast in the system information;

6.2.3.7 Inter-RAT Cell reselection / From E-UTRA RRC_IDLE to HRPD Idle / HRPD cell is higher reselection priority than E-UTRA

6.2.3.7.1 Test Purpose (TP)

(1)

with { UE in E-UTRA RRC_IDLE state and UE detects the cell re-selection criteria that HRPD cell is higher reselection priority than E-UTRAN serving cell }

ensure that { when { UE searches for and measures HRPD cell at least every T_{higher_priority_search}

and Srxlev,HRPD > Thresh_{X, HighP} }

then { UE reselects the HRPD cell }

}

6.2.3.7.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 36.304, clause 5.2.4.1, 5.2.4.2 and 5.2.4.5 and TS 36.133, clause 4.2.2.5 and 4.2.2.5.4.

[TS 36.304, clause 5.2.4.1]

Absolute priorities of different E-UTRAN frequencies or inter-RAT frequencies may be provided to the UE in the system information , in the RRCConnectionRelease message, or by inheriting from another RAT at inter-RAT cell (re)selection. In the case of system information, an E-UTRAN frequency or inter-RAT frequency may be listed without providing a priority (i.e. the field cellReselectionPriority is absent for that frequency). If priorities are provided in dedicated signalling, the UE shall ignore all the priorities provided in system information. If UE is in camped on any cell state, UE shall only apply the priorities provided by system information from current cell, and the UE preserves priorities provided by dedicated signalling unless specified otherwise. When the UE in camped normally state, has only dedicated priorities other than for the current frequency, the UE shall consider the current frequency to be the lowest priority frequency (i.e. lower than the eight network configured values). While the UE is camped on a suitable CSG cell, the UE shall always consider the current frequency to be the highest priority frequency (i.e. higher than the eight network configured values), irrespective of any other priority value allocated to this frequency. The UE shall delete priorities provided by dedicated signalling when:

– the UE enters RRC_CONNECTED state; or

– the optional validity time of dedicated priorities (T320) expires; or

– a PLMN selection is performed on request by NAS [5].

NOTE: Equal priorities between RATs are not supported.

The UE shall only perform cell reselection evaluation for E-UTRAN frequencies and inter-RAT frequencies that are given in system information and for which the UE has a priority provided.

[TS 36.304, clause 5.2.4.2]

Following rules are used by the UE to limit needed measurements:

– If S_intrasearch is sent in the serving cell and S_ServingCell> S_intrasearch, UE may choose to not perform intra-frequency measurements.

– If SServingCell <= Sintrasearch, or S_intrasearch is not sent in the serving cell UE shall perform intra-frequency measurements.

– If S_{nonintrasearch} is sent in the serving cell and SServingCell > Snonintrasearch UE may choose not to perform measurements of E-UTRAN inter-frequencies or inter-RAT frequency cells of equal or lower priority.

– If SServingCell <= Snonintrasearch or S_{nonintrasearch} is not sent in the serving cell the UE shall perform measurements of E-UTRAN inter-frequencies or inter-RAT frequency cells of equal or lower priority according to [10].

Where S_ServingCell is the Srxlev-value of the serving cell.

[TS 36.304, clause 5.2.4.5]

If ThreshX-Q is provided, cell reselection to a cell on a higher priority E-UTRAN frequency or inter-RAT frequency than the serving frequency shall be performed if:

– A cell of a higher priority RAT/ frequency fulfils Squal > Thresh_{X, HighQ} during a time interval Treselection_RAT; and

More than 1 second has elapsed since the UE camped on the current serving cell.

Otherwise, cell reselection to a cell on a higher priority E-UTRAN frequency or inter-RAT frequency than the serving frequency shall be performed if:

– A cell of a higher priority RAT/ frequency fulfils Srxlev > Thresh_{X, HighP} during a time interval Treselection_RAT; and

More than 1 second has elapsed since the UE camped on the current serving cell.

Cell reselection to a cell on an equal priority E-UTRAN frequency shall be based on ranking for Intra-frequency cell reselection as defined in sub-clause 5.2.4.6.

If ThreshX-Q is provided, cell reselection to a cell on a lower priority E-UTRAN frequency or inter-RAT frequency than the serving frequency shall be performed if:

– The serving cell fulfils Squal < Thresh_{Serving, LowQ} and a cell of a lower priority RAT/ frequency fulfils Squal > Thresh_{X, LowQ} during a time interval Treselection_RAT; and

– More than 1 second has elapsed since the UE camped on the current serving cell.

Otherwise, cell reselection to a cell on a lower priority E-UTRAN frequency or inter-RAT frequency than the serving frequency shall be performed if:

– The serving cell fulfils Srxlev < Thresh_{Serving, LowP} and a cell of a lower priority RAT/ frequency fulfils Srxlev > Thresh_{X, LowP}during a time interval Treselection_RAT; and

– More than 1 second has elapsed since the UE camped on the current serving cell.

Cell reselection to a higher priority RAT/ frequency shall take precedence over a lower priority RAT/ frequency, if multiple cells of different priorities fulfil the cell reselection criteria.

For cdma2000 RATs, Srxlev is equal to -FLOOR(-2 x 10 x log10 Ec/Io) in units of 0.5 dB, as defined in [18], with Ec/Io referring to the value measured from the evaluated cell.

For cdma2000 RATs, Thresh_{X, HighP} and Thresh_{X, LowP} are equal to -1 times the values signalled for the corresponding parameters in the system information.

[TS 36.133, clause 4.2.2.5]

If the SServingCellof the E-UTRA serving cell is greater than S_{nonintrasearch}, then the UE shall search for inter-RAT layers of higher priority at least every T_{higher_priority_search}where T_{higher_priority_search} is described in section 4.2.2.

If the S_{ServingCellof the E-UTRA} serving cell is less than or equal to S_{nonintrasearch}then the UE shall search for and measure inter-RAT layers of higher, lower priority in preparation for possible reselection. In this scenario, the minimum rate at which the UE is required to search for and measure higher priority inter-RAT layers shall be the same as that defined below for lower priority RATs.

[TS 36.133, clause 4.2.2.5.4]

In order to perform measurement and cell reselection to HRPD cell, the UE shall acquire the timing of HRPD cells.

When the measurement rules indicate that HRPD cells are to be measured, the UE shall measure CDMA2000 HRPD Pilot Strength of HRPD cells in the neighbour cell list at the minimum measurement rate specified in this section.

The parameter ‘Number of HRPD Neighbour Frequency’, which is transmitted on E-UTRAN BCCH, is the number of carriers used for all HRPD cells in the neighbour cell list.

The UE shall be capable of evaluating that the HRPD cell has met cell reselection criterion defined in [1] within T_evaluateHRPD.

Table 4.2.2.5.4-1 gives values of T_measureHRPDand T_{evaluateHRPD.}

6.2.3.7a Inter-RAT Cell reselection / From E-UTRA RRC_IDLE to HRPD Idle / HRPD cell is higher reselection priority than E-UTRA (Srxlev > Thresh_{HRPD, HighP})

6.2.3.7a.1 Test Purpose (TP)

(1)

with { UE in E-UTRA RRC_IDLE }

ensure that {

when { UE detects a HRPD cell with higher reselection priority than the E-UTRAN serving cell }

then { UE does not reselect the HRPD cell }

}

Note: The UE is expected during this time to do measurements on the HRPD cell at least every T_{higher_priority_search} but this cannot be easily verified

(2)

with { UE in E-UTRA RRC_IDLE having detected a HRPD cell with higher reselection priority than the E-UTRAN serving cell } ensure that {

when { Srxlev,HRPD > Thresh_{HRPD, HighP}}

then { UE reselects the HRPD cell }

}

6.2.3.7a.2 Conformance requirements

References: The conformance requirements covered in the present TC are specified in: TS 36.304, clause 5.2.4.1, 5.2.4.2 and 5.2.4.5 and TS 36.133, clause 4.2.2.5 and 4.2.2.5.4.

[TS 36.304, clause 5.2.4.1]

Absolute priorities of different E-UTRAN frequencies or inter-RAT frequencies may be provided to the UE in the system information, in the RRCConnectionRelease message, or by inheriting from another RAT at inter-RAT cell (re)selection. In the case of system information, an E-UTRAN frequency or inter-RAT frequency may be listed without providing a priority (i.e. the field cellReselectionPriority is absent for that frequency). If priorities are provided in dedicated signalling, the UE shall ignore all the priorities provided in system information. If UE is in camped on any cell state, UE shall only apply the priorities provided by system information from current cell, and the UE preserves priorities provided by dedicated signalling unless specified otherwise. When the UE in camped normally state, has only dedicated priorities other than for the current frequency, the UE shall consider the current frequency to be the lowest priority frequency (i.e. lower than the eight network configured values). While the UE is camped on a suitable CSG cell, the UE shall always consider the current frequency to be the highest priority frequency (i.e. higher than the eight network configured values), irrespective of any other priority value allocated to this frequency. The UE shall delete priorities provided by dedicated signalling when:

the UE enters RRC_CONNECTED state; or
the optional validity time of dedicated priorities (T320) expires; or
a PLMN selection is performed on request by NAS [5].

NOTE: Equal priorities between RATs are not supported.

The UE shall only perform cell reselection evaluation for E-UTRAN frequencies and inter-RAT frequencies that are given in system information and for which the UE has a priority provided.

The UE shall not consider any black listed cells as candidate for cell reselection.

NOTE: The network may assign dedicated cell reselection priorities for frequencies not configured by system information.

[TS 36.304, clause 5.2.4.2]

When evaluating Srxlev and Squal of non-serving cells for reselection purposes, the UE shall use parameters provided by the serving cell.

Following rules are used by the UE to limit needed measurements:

– If the serving cell fulfils Srxlev> S_IntraSearchP and Squal > S_IntraSearchQ, the UE may choose not to perform intra-frequency measurements.

– Otherwise, the UE shall perform intra-frequency measurements.

– Otherwise, the UE shall perform measurements of E-UTRAN inter-frequencies or inter-RAT frequency cells of equal or lower priority according to [10].

[TS 36.304, clause 5.2.4.5]

– A cell of a higher priority EUTRAN or UTRAN FDD RAT/ frequency fulfils Squal > Thresh_{X, HighQ} during a time interval Treselection_RAT; or

– A cell of a higher priority UTRAN TDD, GERAN or CDMA2000 RAT/ frequency fulfils Srxlev > Thresh_{X, HighP} during a time interval Treselection_RAT; and

More than 1 second has elapsed since the UE camped on the current serving cell.

Otherwise, cell reselection to a cell on a higher priority E-UTRAN frequency or inter-RAT frequency than the serving frequency shall be performed if:

– A cell of a higher priority RAT/ frequency fulfils Srxlev > Thresh_{X, HighP} during a time interval Treselection_RAT; and

More than 1 second has elapsed since the UE camped on the current serving cell.
