14.1.2 Intra-frequency reporting events for FDD

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

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

Within the measurement reporting criteria field in the Measurement Control message the UTRAN notifies the UE which events should trigger a measurement report. If present, the "reporting criteria for secondary UL frequency" notifies the UE which events should trigger a measurement report for the secondary uplink frequency. The listed events are the toolbox from which the UTRAN can choose the reporting events that are needed for the implemented handover evaluation function, or other radio network functions. If present, the IE "Cells to be excluded in detected set cells" notifies the UE to exclude cells from corresponding measurement report and UE shall exclude indicated cells from measurement report for intra-frequency measurement.

All the specified events are measured with respect to any of the measurement quantities given in subclause 14.1.1. The measurement quantities are measured on the monitored primary common pilot channels (CPICH) of the cell defined in the measurement object and measurement object on secondary UL frequency.

Special mechanisms for the events are illustrated in subclause 14.1.4 and 14.1.5.

NOTE: The events below are numbered 1A, 1B, 1C,… since all intra-frequency reporting events would be labelled 1X, inter-frequency reporting events would be labelled 2X, and so on for the other measurement types.

When one intra-frequency measurement identity corresponds to multiple intra-frequency events with identical event identities, the UE behaviour is not specified.

14.1.2.1 Reporting event 1A: A Primary CPICH enters the reporting range

When an intra-frequency measurement configuring event 1a is set up, the UE shall:

1> create a variable TRIGGERED_1A_EVENT per active set related to that measurement, which shall initially be empty;

1> delete the corresponding variable when the measurement is released.

When event 1A is configured in the UE, the UE shall:

Figure 14.1.2.3-1 [Informative]: A primary CPICH that is not included in the active set becomes better than a primary CPICH that is in the active set

In this figure, the parameters hysteresis and time to trigger, as well as the cell individual offsets for all cells are equal to 0. In this example the cells belonging to primary CPICH 1 and 2 are in the active set, but the cells transmitting primary CPICH 3 and CPICH 4 are not (yet) in the active set.

The first measurement report is sent when primary CPICH 4 becomes better than primary CPICH 2. The "cell measurement event result" of the measurement report contains the information of primary CPICH 4 and CPICH 2.

Assuming that the active set has been updated after the first measurement report (active set is now primary CPICH 1 and primary CPICH 4), the second report is sent when primary CPICH 3 becomes better than primary CPICH 1. The "cell measurement event result" of the second measurement report contains the information of primary CPICH 3 and primary CPICH 1.

Equation 1 (Triggering condition for pathloss)

Equation 2 (Triggering condition for all the other measurement quantities)

Equation 3 (Leaving triggering condition for pathloss)

Equation 4 (Leaving triggering condition for all the other measurement quantities)

The variables in the formula are defined as follows:

M_Old is the measurement result of a cell that becomes worse than an absolute threshold

CIO_Old is the individual cell offset for the cell becoming worse than the absolute threshold. Otherwise it is equal to 0.

T_1f is an absolute threshold

H_1f is the hysteresis parameter for the event 1f.

If the measurement results are pathloss or CPICH-Ec/No then M_Old is expressed as ratios.

If the measurement result is CPICH-RSCP then M_Old is expressed in mW.

14.1.2.7 Reporting event 1J: A non-active E-DCH but active DCH primary CPICH becomes better than an active E-DCH primary CPICH

When an intra-frequency measurement configuring event 1j is set up, the UE shall:

1> create a variable TRIGGERED_1J_EVENT related to that measurement, which shall initially be empty;

1> delete this variable when the measurement is released.

When event 1J is configured in the UE, the UE shall:

2> if all required reporting quantities are available for that cell; and

2> if the equations have been fulfilled for a time period indicated by "Time to trigger", and if the primary CPICH that is better is not included in the E-DCH active set but included in DCH active set and the other primary CPICH is any of the primary CPICHs included in the E-DCH active set, and if that first primary CPICH is not included in the "cells triggered" in the variable TRIGGERED_1J_EVENT:

3> include that primary CPICH in the "cells recently triggered" in the variable TRIGGERED_1J_EVENT.

1> if the value of "Replacement activation threshold" for this event is less than or equal to the current number of cells in the E-DCH active set or equal to 0 and if any primary CPICHs are stored in the "cells recently triggered" in the variable TRIGGERED_1J_EVENT:

2> if "Reporting interval" for this event is not equal to 0:

3> if the IE "Periodical reporting running" in the variable TRIGGERED_1J_EVENT is set to FALSE:

4> start a timer for with the value of "Reporting interval" for this event and set the IE "Periodical reporting running" in the variable TRIGGERED_1J_EVENT to TRUE.

3> set "sent reports" for that primary CPICH in the variable TRIGGERED_1J_EVENT to 1.

2> send a measurement report with IEs set as below:

3> set in "intra-frequency measurement event results": "Intrafrequency event identity" to "1J"; and

3> include in "cell measurement event results" all entries of the "cells recently triggered" in the variable TRIGGERED_1J_EVENT not in the E-DCH active set but included in DCH active set as well as the "primary CPICH info" of all the primary CPICHs in the E-DCH active set for which the measured value is worse (i.e. greater for pathloss and less for the other measurement quantities) than the one of the entry in "cell recently triggered" that has the best measured value taking into account their cell individual offset. The "primary CPICH info" for those cells shall be ordered according to their measured value taking into account their cell individual offset, beginning with the best cell to the worst one;

3> set the IE "measured results" and the IE "additional measured results" according to subclause 8.4.2, not taking into account the cell individual offset for each cell.

2> move all entries from "cells recently triggered" to "cells triggered" in the variable TRIGGERED_1J_EVENT.

1> if the timer for the periodical reporting has expired:

2> if any primary CPICH is included in the "cells triggered" in the variable TRIGGERED_1J_EVENT, and not included in the current E-DCH active set but included in DCH active set:

3> if "Reporting interval" for this event is not equal to 0, and if "Amount of reporting" is greater than "sent reports" stored for that primary CPICH, in "cells triggered" in the variable TRIGGERED_1J_EVENT:

4> increment the stored counter "sent reports" for all CPICH in "cell triggered" in variable TRIGGERED_1J_EVENT;

4> start a timer with the value of "Reporting interval" for this event;

4> send a measurement report with IEs set as below:

5> set in "intra-frequency measurement event results": "Intrafrequency event identity" to "1J"; and

5> include in "cell measurement event results" all entries of the variable TRIGGERED_1J_EVENT with value of IE "sent report" equal to or smaller than value of "Amount of reporting" and that are not part of the E-DCH active set but included in DCH active set as well as the "primary CPICH info" of all the primary CPICHs in the E-DCH active set for which the measured value is worse (i.e. greater for pathloss and less for the other measurement quantities) than the one of the entry in "cell triggered" that has the best measured value, ordering the "primary CPICH info" according to their measured value beginning with the best cell to the worst one, taking into account the cell individual offset for each cell;

5> set the IE "measured results" and the IE "additional measured results" according to subclause 8.4.2, not taking into account the cell individual offset for each cell.

4> if "sent reports" in variable TRIGGERED_1J_EVENT is equal to "Amount of reporting" for all entries:

5> set the IE "Periodical Reporting running" in the variable TRIGGERED_1J_EVENT to FALSE and disable the timer for the periodical reporting.

1> if a primary CPICH is added to the E-DCH active set:

2> if that primary CPICH is included in the "cells triggered" or "cells recently triggered" in the variable TRIGGERED_1J_EVENT:

3> remove the entry of that primary CPICH from "cells triggered" or "cells recently triggered" in the variable TRIGGERED_1J_EVENT.

3> if no entry in the variable TRIGGERED_1J_EVENT has a value of "sent reports" smaller than "Amount of reporting" or

3> if there is no entry in the variable TRIGGERED_1J_EVENT:

4> if the reporting interval timer is running:

5> stop the reporting interval timer;

5> set the IE "Periodical reporting running" in the variable TRIGGERED_1J_EVENT to FALSE.

Equation 1 (Triggering condition for pathloss)

Equation 2 (Triggering condition for all the other measurement quantities)

Equation 3 (Leaving triggering condition for pathloss)

Equation 4 (Leaving triggering condition for all the other measurement quantities)

The variables in the formula are defined as follows:

M_New is the measurement result of the cell not included in the E-DCH active set but included in DCH active set.

CIO_New is the individual cell offset for the cell not included in the E-DCH active set but included in DCH active set becoming better than the cell in the E-DCH active set if an individual cell offset is stored for that cell. Otherwise it is equal to 0.

For pathloss:

M_InAS is the measurement result of the cell in the E-DCH active set with the highest measurement result.

For other measurement quantities:

M_InAS is the measurement result of the cell in the E-DCH active set with the lowest measurement result.

CIO_InAS is the individual cell offset for the cell in the E-DCH active set that is becoming worse than the new cell.

H_1J is the hysteresis parameter for the event 1J.

If the measurement results are pathloss or CPICH-Ec/No then M_New and M_inAS are expressed as ratios.

If the measurement result is CPICH-RSCP then M_New and M_inAS are expressed in mW.

Figure 14.1.2.7-1 [Informative]: A primary CPICH that is not included in the E-DCH active set but included in DCH active set becomes better than a primary CPICH that is in the E-DCH active set

In this figure, the parameters hysteresis and time to trigger, as well as the cell individual offsets for all cells are equal to 0 and replacement activation threshold is equal to 0 or 1 or 2. In this example the cells belonging to primary CPICH 1 and 2 are in the E-DCH active set, but the cells transmitting primary CPICH 3 and CPICH 4 are not (yet) in the E-DCH active set but included in DCH active set.

Assuming that the E-DCH active set has been updated after the first measurement report (E-DCH active set is now primary CPICH 1 and primary CPICH 4), the second report is sent when primary CPICH 3 becomes better than primary CPICH 1. The "cell measurement event result" of the second measurement report contains the information of primary CPICH 3 and primary CPICH 1.
