34.123-13GPPPart 1: Protocol conformance specificationRelease 15TSUser Equipment (UE) conformance specification

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

6.1.2.1 Cell reselection

6.1.2.1.1 Definition

Test to verify that the UE performs the cell reselection correctly for intra/inter-frequency cells if the serving cell becomes barred or S<0.

6.1.2.1.2 Conformance requirement

1. When camped on a cell, the UE shall regularly search for a better cell according to the cell reselection criteria. If a better cell is found, that cell is selected. The change of cell may imply a change of RAT.

2. A "suitable cell" is a cell on which the UE may camp on to obtain normal service. Such a cell shall fulfil all the following requirements.

2.1 The cell is part of the selected PLMN or of a PLMN considered as equivalent by the UE according to the information provided by the NAS.

2.2 The cell is not barred.

2.3 The cell is not part of the list of "forbidden LAs for roaming".

2.4 The cell selection criteria are fulfilled.

3. When camped normally, the UE shall execute the cell reselection evaluation process on the following occasions/triggers:

3.1 UE internal triggers, so as to meet performance as specified in TS 25.133 for FDD mode and in TS 25.123 for TDD mode.

3.2 When information on the BCCH used for the cell reselection evaluation procedure has been modified.

4. Cell Reselection Criteria:

4.1 The UE shall perform ranking of all cells that fulfil the S criterion.

4.2 The cells shall be ranked according to the R criteria, deriving Qmeas,n and Qmeas,s and calculating the R values using CPICH RSCP, P-CCPCH RSCP and the averaged received signal level as specified in TS 25.133 and TS 25.123 for FDD, TDD and GSM cells, respectively.

The offset Qoffset1_s,nis used for Qoffset_s,nto calculate R_n, the hysteresis Qhyst1_s is used for Qhyst_s to calculate R_s.

If the usage of HCS is indicated in system information, TEMP_OFFSET1_n is used for TEMP_OFFSET_n to calculate TO_n. If it is indicated in system information that HCS is not used, TEMP_OFFSET_n is not applied when calculating R_n. The best ranked cell is the cell with the highest R value.

If a TDD cell is ranked as the best cell, the UE shall perform cell re-selection to that TDD cell.

If an FDD cell is ranked as the best cell and the quality measure for cell selection and re-selection is set to CPICH RSCP, the UE shall perform cell re-selection to that FDD cell.

4.3 In all cases, the UE shall reselect the new cell, only if the following conditions are met:

– the new cell is better ranked than the serving cell during a time interval Treselection.

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

5. When cell status "barred" is indicated, the UE shall select another cell according to the following rule:

5.1 If the "Intra-frequency cell re-selection indicator" IE in Cell Access Restriction IE is set to value "allowed", the UE may select another cell on the same frequency if selection/re-selection criteria are fulfilled.

– If the UE is camping on another cell, the UE shall exclude the barred cell from the neighbouring cell list until the expiry of a time interval T_barred. The time interval T_barred is sent via system information in a barred cell together with Cell status information in the Cell Access Restriction IE.

– If the UE does not select another cell, and the barred cell remains to be the "best" one, the UE shall after expiry of the time interval T_barred again check whether the status of the barred cell has changed.

5.2 If the "Intra-frequency cell re-selection indicator" IE is set to "not allowed" the UE shall not re-select a cell on the same frequency as the barred cell. For emergency call, the Intra-frequency cell re-selection indicator IE" shall be ignored, i.e. even if it is set to "not allowed" the UE may select another intra-frequency cell.

6.1.2.3 HCS Cell reselection

6.1.2.3.1 Definition

Test to verify that the UE performs the cell reselection correctly for hierarchical cell structures. This shall be done according to the HCS priority, the received signal quality value Q and the quality level threshold criterion H.

6.1.2.3.2 Conformance requirement

1. When camped normally, the UE shall execute the cell reselection evaluation process on the following occasions/triggers:

1.1 UE internal triggers, so as to meet performance as specified in TS 25.133 for FDD mode and in TS 25.123 for TDD mode.

1. When cell status is indicated as "not barred", "not reserved" for operator use and "not reserved" for future extension (Cell Reservation Extension),

– the UE may select/re-select this cell during the cell selection and cell re-selection procedures in Idle mode and in Connected mode.

2. When cell status is indicated as "not barred", "not reserved" for operator use and "reserved" for future extension (Cell Reservation Extension),

– UEs shall behave as if cell status "barred" is indicated using the value "not allowed" in the IE "Intra-frequency cell re-selection indicator" and the maximum value for T_barred, see [8] (see also below).

3. When cell status is indicated as "not barred" and "reserved" for operator use,

– UEs assigned to Access Class 11 or 15 may select/re-select this cell if in the home PLMN.

– UEs assigned to an Access Class in the range 0 to 9 and 12 to 14 shall behave as if cell status "barred" is indicated using the value "not allowed" in the IE "Intra-frequency cell re-selection indicator" and the maximum value for T_barred, see [8] (see also below).

4. When cell status "barred" is indicated,

– The UE is not permitted to select/re-select this cell, not even for emergency calls.

– The UE shall ignore the "Cell Reserved for future extension (Cell Reservation Extension) use" IE.

– The UE shall select another cell according to the following rule:

– If the "Intra-frequency cell re-selection indicator" IE in Cell Access Restriction IE is set to value "allowed", the UE may select another cell on the same frequency if selection/re-selection criteria are fulfilled.

– If the "Intra-frequency cell re-selection indicator" IE is set to "not allowed" the UE shall not re-select a cell on the same frequency as the barred cell. For emergency call, the Intra-frequency cell re-selection indicator IE" shall be ignored, i.e. even if it is set to "not allowed" the UE may select another intra-frequency cell.

– If the barred cell remains to be the "best" one, the UE shall after expiry of the time interval T_barred again check whether the status of the barred cell has changed.

The reselection to another cell may also include a change of RAT.

6.1.2.10 HCS inter-frequency cell reselection

6.1.2.10.1 Definition

Test to verify that the UE performs inter-frequency cell reselection correctly for hierarchical cell structures in FDD. This shall be done according to the received signal quality value Q and the quality level thresholds Sintrasearch, Sintersearch and SsearchHCS.

6.1.2.10.2 Conformance requirement

1. When camped normally, the UE shall execute the cell reselection evaluation process on the following occasions/triggers:

1.1 UE internal triggers, so as to meet performance as specified in TS 25.133 for FDD mode.

1.2 When information on the BCCH used for the cell reselection evaluation procedure has been modified.

2. Cell Reselection Criteria for hierarchical cells:

2.1 The quality level thresholds for measurement rules for cell reselection can be used to control inter-frequency cell reselections. Intra-frequency cell reselections shall still be performed if Sintrasearch is not sent.

2.2 The quality level threshold criterion H for hierarchical cell structures is used to determine whether prioritised ranking according to hierarchical cell re-selection rules shall apply, and is calculated from the Q, Qhcs, TEMP_OFFSET and PENALTY_TIME parameters.

2.3 The UE shall perform ranking of all cells that fulfil the S criterion among all cells that have the highest HCS_PRIO among those cells that fulfil the criterion H >= 0.

2.4 The cells shall be ranked according to the R criteria. The best ranked cell is the cell with the highest R value. If an FDD cell is ranked as the best cell, the UE shall perform cell re-selection to that FDD cell. If a TDD cell is ranked as the best cell, the UE shall perform cell re-selection to that TDD cell.

2.5 In all cases, the UE shall reselect the new cell, only if the cell reselection criteria are fulfilled during a time interval Treselection.

2.6 The cell-ranking criterion R is derived from Q, Qhyst, Qoffset, TEMP_OFFSET, PENALTY_TIME.

6.1.2.10.3 Test purpose

1. Verify that in FDD the UE ignores inter-frequency cells for reselection when the inter-frequency cells have equal or lower HCS priority than the serving cell, and Sintraseach is not sent, and Sintersearch < Squal and SsearchHCS < Srxlev.

2. Verify that in FDD the UE reselect to an inter-frequency cells when Sintraseach is not sent, and Sintersearch < Squal but SsearchHCS > Srxlev. The modification of this parameter on the BCCH shall trigger the cell reselection evaluation process. Qhyst, Qoffset, TEMP_OFFSET, PENALTY_TIME and Treselection are not applied so R equals CPICH_RSCP for FDD cells.

6.1.2.11 Cell reselection in shared network environment

6.1.2.11.1 Definition

Test to verify that the UE performs cell reselection according to core specification 25.304 in a shared network environment (FDD). Correct handling of equivalent PLMNs is also verified.

6.1.2.11.2 Conformance requirement

1. suitable cell:

A "suitable cell" is a cell on which the UE may camp on to obtain normal service. Such a cell shall fulfil all the following requirements.

– The cell shall be part of either:

the selected PLMN, or:
the registered PLMN, or:
a PLMN of the Equivalent PLMN list

according to the latest information provided by the NAS.

– The cell is not barred, see subclause 5.3.1.1;

– The cell is part of at least one LA that is not part of the list of "forbidden LAs for roaming" [9], which belongs to a PLMN that fulfils the first bullet above;

– The cell selection criteria are fulfilled, see subclause 5.2.3.1.2.

If the IE “Multiple PLMN List” [4] is broadcast in the cell, the cell is considered to be part of all LAs with LAIs constructed from the PLMN identities in the “Multiple PLMN List” and the LAC broadcast in the cell.

2. When camped on a cell, the UE shall regularly search for a better cell according to the cell reselection criteria. If a better cell is found, that cell is selected. The change of cell may imply a change of RAT.

3. When camped normally, the UE shall perform the following tasks:

– select and monitor the indicated PICH and PCH of the cell as specified in clause 8 according to information sent in system information;

– monitor relevant System Information. This is specified in [4];

– perform necessary measurements for the cell reselection evaluation procedure;

– execute the cell reselection evaluation process on the following occasions/triggers:

1) UE internal triggers, so as to meet performance as specified in [10] and [11];

2) When information on the BCCH used for the cell reselection evaluation procedure has been modified

4. Cell Reselection Criteria:

4.1 If HCS is not used in the serving cell the UE shall perform ranking of all cells that fulfil the criterion S, among:

– all measured cells (see subclause 5.2.6.1.1).

The offset Qoffset1_s,nis used for Qoffset_s,nto calculate R_n, the hysteresis Qhyst1_s is used for Qhyst_s to calculate R_s.

…

If an FDD cell is ranked as the best cell and the quality measure for cell selection and re-selection is set to CPICH RSCP, the UE shall perform cell re-selection to that FDD cell.

4.3 In all cases, the UE shall reselect the new cell, only if the following conditions are met:

– the new cell is better ranked than the serving cell during a time interval Treselection.

…

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

5. Location Registration

In the UE, the AS shall report registration area information to the NAS.

If the UE reads more than one PLMN identity in the current cell, the UE shall report the found PLMN identities that make the cell suitable in the registration area information to NAS.

6. Location updating accepted by the network

The network may also send a list of "equivalent PLMNs" in the LOCATION UPDATING ACCEPT message. Each entry of the list contains a PLMN code (MCC+MNC). The mobile station shall store the list, as provided by the network, except that any PLMN code that is already in the "forbidden PLMN list" shall be removed from the "equivalent PLMNs" list before it is stored by the mobile station. In addition the mobile station shall add to the stored list the PLMN code of the registered PLMN that sent the list. All PLMNs in the stored list shall be regarded as equivalent to each other for PLMN selection, cell selection/re-selection and handover. The stored list in the mobile station shall be replaced on each occurrence of the LOCATION UPDATING ACCEPT message. If no list is contained in the message, then the stored list in the mobile station shall be deleted. The list shall be stored in the mobile station while switched off so that it can be used for PLMN selection after switch on.

6.1.2.12 Cell reselection based on absolute priority in SIB19

6.1.2.12.1 Definition

Test to verify that the UE performs cell reselection based on absolute RAT priority defined in SIB 19.

6.1.2.12.2 Conformance requirement

5.2.6.1.2a Measurement rules for inter-frequency and inter-RAT cell reselection when

absolute priorities are used

…

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

– The UE shall perform measurements of inter-frequency layers with a priority higher than the priority of the

current serving layer.

NOTE: The rate of these measurements may vary depending on whether Srxlev and Squal of the serving cell are

above or below Sprioritysearch1 and Sprioritysearch2. This is specified in [10].

…

– For inter-frequency layers with a priority equal or lower than the priority of the current serving layer:

– If SrxlevServingCell > Sprioritysearch1 and SqualServingCell > Sprioritysearch2 the UE may choose not to perform measurements of inter-frequency layers of equal or lower priority.

– If SrxlevServingCell <= Sprioritysearch1 or SqualServingCell <= Sprioritysearch2 the UE shall perform measurements of

inter-frequency layers of equal or lower priority.

– The UE shall not perform measurements of inter-frequency layers for which the UE has no absolute priority.

…

5.2.6.1.4a Absolute priority based criteria for inter-frequency and inter-RAT cell reselection

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.

If System Information Block 18 with UTRAN information is provided then the UE shall apply the inter-frequency

priority rules below only to UTRAN cells of the selected PLMN or equivalent PLMNs. If System Information Block 18

is not provided, or is provided but contains no information for UTRAN, then the rules below apply for the entire

UTRAN RAT.

…

If priority information is provided for any inter-frequency layers, cells belonging to inter-frequency layers for which no

priority or no threshold is assigned shall not be considered for reselection.

…

If none of the inter-frequency layers in UTRAN are provided with both priority and threshold parameters, the cell

reselection criteria in subclause 5.2.6.1.4 shall apply for inter-frequency layers in UTRAN.

…

If both criteria in subclause 5.2.6.1.4 and criteria in subclause 5.2.6.1.4a are simultaneously fulfilled, the order in which

the reselection criteria are evaluated is left to UE implementation.

…

The UE may apply either priorities broadcast in system information or priorities received through dedicated signalling.

The rules regarding which set of priorities shall apply are defined in [4]. UE specific priorities are only valid in the

RPLMN, and shall be cleared when the validity time of the UE specific priorities expires, or when leaving the RPLMN.

UE specific priorities are not applied in camped on any cell state.

…

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

– Criterion 1: the SrxlevnonServingCell,x of a cell on an evaluated higher absolute priority layer is greater than

Threshx,high during a time interval Treselection;

– Criterion 2: SrxlevServingCell < Threshserving,low or SqualServingCell < 0 and the SrxlevnonServingCell,x of a inter-frequency cell on an evaluated equal absolute priority layer is greater than Threshx,low during a time interval Treselection;

– Criterion 3: SrxlevServingCell < Threshserving,low or SqualServingCell < 0 and the SrxlevnonServingCell,x of a cell on an evaluated lower absolute priority layer is greater than Threshx,low during a time interval Treselection;

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

– Criterion 4: the SqualnonServingCell,x of a cell on an evaluated higher absolute priority layer is greater than

Threshx,high2 during a time interval Treselection;

– Criterion 5: SqualServingCell < Threshserving,low2 and the SqualnonServingCell,x of a cell on an evaluated lower absolute priority layer is greater than Threshx,low2 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 or 4 is fulfilled.

Cell reselection to an inter-frequency cell on an equal absolute priority layer to the camped frequency shall be performed if criterion 2 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 SrxlevnonServingCell,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.

The UE should not perform cell reselection while the UE has an allocated common E-DCH resource.

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

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

8.6.7.3a UTRA priority info list

If the IE "UTRA priority info list" is received in System Information Block Type 19, the UE shall:

4> create a new entry in the IE "Frequency List" in that occurrence of IE "Priority Info List", and store the value of "UARFCN" in the IE "UARFCN" in this occurrence of the IE "Frequency List" within the variable PRIORITY_INFO_LIST, and in that new entry:

5> store the IEs "Thresh_{x, high}", "Thresh_{x, low}", "QqualminFDD" and "QrxlevminFDD".

3> otherwise:

4> create a new entry in the IE "Priority Info List" and store the value of "priority" in the IE "priority" in this occurrence of the IE "Priority Info List" within the variable PRIORITY_INFO_LIST, and in that new entry:

5> set the CHOICE "Radio Access Technology" to "UTRA FDD" and store the value of "UARFCN" in the IE "UARFCN" in the first occurrence of the IE "Frequency List";

5> store the IEs "Thresh_{x, high}", "Thresh_{x, low}", "QqualminFDD" and "QrxlevminFDD" in that occurrence of the IE "Frequency List".

2> for each occurrence of the IE "UTRAN TDD Frequencies":

5> store the IEs "Thresh_{x, high}", "Thresh_{x, low}" and "QrxlevminTDD".

3> otherwise:

5> set the CHOICE "Radio Access Technology" to "UTRA TDD" and store the value of "UARFCN" in the IE "UARFCN" in the first occurrence of the IE "Frequency List";

5> store the IEs "Thresh_{x, high}", "Thresh_{x, low}" and "QrxlevminTDD" in that occurrence of the IE "Frequency List".

3. To verify that UE performs Equal Priority Cell Reselection based on absolute priority.

6.1.2.12.4 Method of test

Initial conditions

System Simulator:

– 2 cells Cell 1 and Cell 4

– Cell 1 as the active cell with SS downlink transmission power settings according to “T0” in table 6.1.2.x below.

– SIB19 to be transmitted by both cells.

User Equipment:

– UE is in idle mode, registered on Cell 1 with power settings “T0”.

– Idle state (state 3 or state 7) as specified in clause 7.4 of TS 34.108 with a CN UE identity, depending on the CN domain(s) supported by the UE.

Related ICS/IXIT statement(s)

UE supports FDD.

Table 6.1.2.12

Parameter	Unit	Cell 1			Cell 4
Parameter	Unit	T0	T1	T2	T0	T1	T2
UTRA RF Channel Number		Mid Range Test Frequency			High Range Test Frequency
CPICH Ec (FDD)	dBm/3.84MHz	-60	-60	-76	-90	-65	-74
Srxlev*	dB	21	21	5	-9	16	7
qRxLevMinFDD	dB	-81			-81
Note-Srxlev is calculated in UE. During T1, UE should meet higher priority cell reselection criteria. During T2, UE should meet lower priority cell reselection criteria, followed by equal priority cell reselection criteria.

Test procedure

Method C is applied.

SS transmits the MIB with the “MIB Value Tag” IE different from the original setting and SIB TYPE 19 with cell 4 as higher priority cell and cell 1 as lower priority cell (See specific message contents).
SS notifies the UE by sending a PAGING TYPE1 with BCCH modification and waits for 5s to ensure UE has read the SIB information.
SS configures downlink transmission power settings according to columns "T1" in the table 6.1.2.x.
UE meets the higher priority cell reselection and reselects to higher priority cell 4.
SS waits for random access request from UE. A Location Area Update procedure is done for UE. For UE that supports both CS and PS domain or PS domain only, the Location Updating procedure could be replaced by the appropriate GMM registration procedure.
SS transmits SIB TYPE 19 default content for cell 1 and then SS configures downlink transmission power settings according to columns "T2" in table 6.1.2.x.SS transmits the MIB with the “MIB Value Tag” IE different from the original setting and SIB TYPE 19 for cell 4 as indicated in specific message contents SS notifies the UE by sending a PAGING TYPE1 with BCCH modification and waits for 5s to ensure UE has read the SIB information UE meets the lower priority cell reselection criteria and reselects to lower priority cell 1.
SS waits for random access request from UE. A Location Area Update procedure is done for UE. For UE that supports both CS and PS domain or PS domain only, the Location Updating procedure could be replaced by the appropriate GMM registration procedure.
SS transmits the MIB with the "MIB Value Tag" IE different from the original setting and the SIB TYPE 19 where both Cell 1 and Cell 4 are defined as equal priority cells.
SS notifies the UE by sending PAGING TYPE1 with BCCH modification and waits for 5s to ensure UE has read all the SIB information.
UE meets the equal priority cell reselection criteria with same power level as “T2” and reselects to equal priority cell 4.
SS waits for random access request from UE. A Location Area Update procedure is done for UE. For UE that supports both CS and PS domain or PS domain only, the Location Updating procedure could be replaced by the appropriate GMM registration procedure.
