A cell shall be considered detectable when
– RSRP related side conditions given in TS 36.133 [4] Clauses 9.1.21.3 and 9.1.21.4 are fulfilled for a corresponding Band,
– SCH_RP and SCH Ês/Iot according to TS 36.133 [4] Table B.2.14-3 for a corresponding Band.
Identification of a cell shall include detection of the cell and additionally performing a single measurement with measurement period of Tmeasure_intra_UE cat M1. If higher layer filtering is used, an additional cell identification delay can be expected.
In the RRC_CONNECTED state the measurement period for intra frequency measurements is according to Table 8.1.35.3-1. When measurement gaps are activated the UE shall be capable of performing measurements for at least 6 cells. If the UE has identified more than 6 cells, the UE shall perform measurements but the reporting rate of RSRP measurements of cells from UE physical layer to higher layers may be decreased.
Reported RSRP measurement contained in event triggered measurement reports shall meet the requirements in TS 36.133 [4] Clauses 9.1.21.3 and 9.1.21.4.
The UE shall not send any event triggered measurement reports, as long as no reporting criteria are fulfilled.
The measurement reporting delay is defined as the time between an event that will trigger a measurement report and the point when the UE starts to transmit the measurement report over the air interface. This requirement assumes that the measurement report is not delayed by other RRC signalling on the DCCH. This measurement reporting delay excludes a delay uncertainty resulted when inserting the measurement report to the TTI of the uplink DCCH. The delay uncertainty is: 2 x TTIDCCH. This measurement reporting delay excludes a delay which caused by no UL resources for UE to send the measurement report.
The event triggered measurement reporting delay, measured without L3 filtering shall be less than T identify intra_UE cat M1 defined in Clause 8.1.35.3. When L3 filtering is used or IDC autonomous denial is configured an additional delay can be expected.
If a cell which has been detectable at least for the time period Tidentify_intra_UE cat M1 defined in Clause 8.1.35.3 becomes undetectable for a period ≤ 5 seconds and then the cell becomes detectable again and triggers an event, the event triggered measurement reporting delay shall be less than TMeasurement_Period_UE cat M1, Intra provided the timing to that cell has not changed more than 50 Ts and the L3 filter has not been used. When L3 filtering is used or IDC autonomous denial is configured, an additional delay can be expected.
The normative reference for this requirement is TS 36.133 [4] clause 8.13.3.1.3.1 and A.8.1.35.

8.1.35.4.2 Test procedure
The test consists of one active cell and one neighbour cell. In the measurement control information, it is indicated to the UE that event-triggered reporting with Event A3 is used. The test consists of two successive time periods, with time durations of T1 and T2 respectively. During time duration T1, the UE shall not have any timing information of Cell 2.
1. Ensure the UE is in State 3A-RF-CE with the condition CEModeB according to TS 36.508 [7] clause 7.2A.3AA.
2. Set the parameters according to T1 in Table 8.1.35.5-1. Propagation conditions are set according to Annex B.1 and B.2. T1 starts.
3. The SS shall transmit the RRCConnectionReconfiguration message.
4. The UE shall transmit the RRCConnectionReconfigurationComplete message.
5. When T1 expires, the SS shall switch the power setting from T1 to T2 as specified in Table 8.1.35.5-1.
6. The UE shall transmit a MeasurementReport message triggered by Event A3. If the overall delays measured from the beginning of time period T2 is less than 3210 ms then the number of successful tests is increased by one. If the UE fails to report the event within the overall delays measured requirement then the number of failure tests is increased by one.
7. After the SS receives the MeasurementReport message in step 6), without waiting for T2 to expire the SS shall transmit the RRCConnectionRelease message to release the RRC connection which includes the release of the established radio bearers as well as all radio resources.
8. Set Cell 2 physical cell identity = ((current cell 2 physical cell identity + 1) mod 14 + 2) for next iteration of the test procedure loop.
9. After the RRC connection release, the SS:
– transmits in Cell 1 a Paging message (including PagingRecord with UE-Identity) for the UE and ensures the UE is in State 3A-CE with the condition CEModeB according to TS 36.508 [7] clause 4.5.3AB (if the paging fails, switches off and on the UE and ensures the UE is in State 3A-RF-CE with the condition CEModeB according to TS 36.508 [7] clause 7.2A.3AA),
or
– switches off and on the UE and ensures the UE is in State 3A-RF-CE with the condition CEModeB according to TS 36.508 [7] clause 7.2A.3AA.
10. Repeat steps 2-9 until the confidence level according to Tables G.2.3-1 in Annex G.2 is achieved.

Note 1 OCNG shall be used such that both cells are fully allocated and a constant total transmitted power spectral density is achieved for all OFDM symbols. Note 2: Interference from other cells and noise sources not specified in the test is assumed to be constant over subcarriers and time and shall be modelled as AWGN of appropriate power for Noc to be fulfilled. Note 3: Ês/Iot, RSRP, SCH_RP and Io levels have been derived from other parameters for information purposes. They are not settable parameters themselves. Note 4: The resources for uplink transmission are assigned to the UE prior to the start of time period T2. |

Note 2
Note 3The overall delays measured is defined as the time from the beginning of time period T2, to the moment the UE send one Event A3 triggered measurement report to Cell 2.
The overall delays measured in the test may be up to 2xTTIDCCH higher than the measurement reporting delays because of TTI insertion uncertainty of the measurement report in DCCH.
The overall delays measured test requirement is expressed as:
Overall delays measured = measurement reporting delay + TTI insertion uncertainty
Measurement reporting delay = Tidentify_intra_UE cat M1
Tidentify_intra_UE cat M1 = 3208
TTI insertion uncertainty = 2 ms
The overall delays measured shall be less than a total of 3210 ms in this test case (note: this gives a total of 3208 ms for measurement reporting delay plus 2 ms for TTI insertion uncertainty).
For the test to pass, the total number of successful tests shall be more than 90% of the cases with a confidence level of 95%.
