14.15 E-UTRA measurement for CELL_FACH (FDD only)

25.3313GPPProtocol specificationRadio Resource Control (RRC)Release 17TS

The measurement is performed only when the UE is in CELL_FACH state. The UE shall, taking advantage of non-transmission gaps, perform E-UTRA RSRP or RSRQ measurements and reporting according to the configuration received in the MEASUREMENT CONTROL message.

14.15.1 E-UTRA measurement for CELL_FACH measurement quantities (FDD only)

A measurement quantity is used by the UE to evaluate whether an E-UTRA measurement for CELL_FACH event has occurred or not.

The measurement quantity for E-UTRA measurement for CELL_FACH can be:

1 E-UTRA RSRP

2 E-UTRA RSRQ

A description of those values can be found in [7] and [8].

14.15.2 E-UTRA measurement for CELL_FACH reporting (FDD only)

For cells whose carrier frequency matches any of the EARFCNs in the list of E-UTRA frequencies that the UE has stored in the variable "EUTRA_FREQUENCY_INFO_LIST_FACH", and for which the Physical Cell Identity is not included in the exclude-list for that frequency, the UE shall:

1> for event-triggered reporting, trigger one measurement report if the measured quality of any cell on a configured E-UTRA frequency exceeds the threshold specified by the IE "Reporting Threshold":

2> for those E-UTRA frequencies where at least one cell exceeds the threshold, set the corresponding bit of the IE "E-UTRA frequency indicator" to 1 in the IE "E-UTRA results for CELL_FACH".

1> for periodical reporting, trigger one periodical report when valid measurements are available:

2> for those E-UTRA frequencies whose at least one cell exceeds the threshold, set the corresponding bit of the IE " E-UTRA frequency indicator" to 1 in the IE "E-UTRA results for CELL_FACH".

After the UE has sent the MEASUREMENT REPORT message, the UE shall:

1> stop the measurement associated with the identity given in the IE "measurement identity".
