37.571-13GPPPart 1: Conformance test specificationRelease 16TSUser Equipment (UE) conformance specification for UE positioning
8.1.3.1 Test purpose
To verify that the E-UTRAN FDD UE Rx – Tx time difference measurement accuracy is within the specified limits under a time-domain measurement resource restriction pattern, and when non-MBSFN ABS is configured in the interfering cells.
8.1.3.2 Test applicability
This test applies to all types of E-UTRA FDD UE release 10 and ECID positioning. Applicability requires support for FGI bit 115.
8.1.3.3 Minimum conformance requirements
NOTE: This measurement is used for UE positioning purposes.
The requirements in this section apply for UE configured with a time-domain measurement resource restriction pattern for PCell measurements. The UE Rx-Tx time difference is measured from the Pcell.
The accuracy requirements in Table 8.1.3.3-1 are valid under the following conditions:
– Cell specific reference signals are transmitted either from one, two or four antenna ports,
– Conditions defined in 36.101[2] Clause 7.3 for reference sensitivity are fulfilled,
– No changes to the uplink transmission timing are applied during the measurement period,
RSRP|dBm according to Annex E.4 for a corresponding Band,
– The time domain measurement resource restriction pattern configured for the PCell indicates at least one subframe per radio frame for performing the PCell measurements,
– Four symbols containing CRS are available in all subframes indicated by the time domain measurement resource restriction pattern.

NOTE 1: When in dBm/15kHz, the minimum Io condition is expressed as the average Io per RE over all REs in that symbol. Io may be different in different symbols within a subframe. NOTE 2: Ts is the basic timing unit defined in TS 36.211. NOTE 3: The same bands and the same Io conditions for each band apply for this requirement as for the corresponding requirement with downlink bandwidth ≤ 3 MHz. NOTE 4: Except Band 29. NOTE 5: Io is defined for the subframes indicated by the time-domain measurement resource restriction pattern for serving cell measurements. The specified Io range applies to CRS and non-CRS symbols. Io may be different in different symbols within a subframe. NOTE 6: CRS Ês/Iot is in subframes indicated for PCell measurements by the time-domain measurement resource restriction pattern. NOTE 7: The condition level is increased by ∆>0, when applicable, as described in TS 36.521-3 [25] Sections I.4.2 and I.4.3. NOTE 8: E-UTRA operating band groups are as defined in Section 4.4.2. NOTE 9: Except Band 32. |
|||||
NOTE: It is up to the UE implementation whether the UE Rx-Tx time difference measurement is performed in any subframe or in subframes indicated by the time-domain measurement resource restriction pattern.
The normative reference for this requirement is TS 36.133 [23] clause 9.1.9.3 and A.9.7.3.
8.1.3.4 Test description
The test has two test points with time delays starting at 32 TS and 5008 TS, respectively.
In this test case, there are two synchronous cells, Cell 1 and Cell 2, on the same RF channel. Cell 1 is the PCell on which UE Rx-Tx is measured, and Cell 2 is the interfering cell. Non-MBSFN ABS pattern is configured in Cell 2 during the entire test.
The tested UE is connected to the PCell and configured to transmit SRS signals periodically. The SRS configuration is provided to the UE before the measurement starts. The UE is configured to report UE Rx–Tx time difference measurement. The test equipment measures the transmit timing of the UE using the transmitted SRS, and measures the receive timing using the downlink CRS. The test equipment then compares the difference of these two timings to the UE Rx-Tx measurement reported by the UE. The UE is configured by higher layers via Cell 1 with a time-domain measurement resource restriction pattern for performing E-UTRAN FDD intra-frequency measurements on PCell. The information for both patterns shall be provided to the UE before the measurement starts.
8.1.3.4.1 Initial conditions
Test Environment: Normal as defined in TS 36.508 [18] clause 4.1.
Frequencies to be tested: According to TS 36.521-1 [24] Annex E table E-1 and TS 36.508 [18] clauses 4.4.2 and 4.3.1.
Channel Bandwidth to be tested: 10 MHz as defined in TS 36.508 [18] clause 4.3.1.
1. Connect the SS (node B emulator) and AWGN noise source to the UE antenna connectors as shown in TS 36.508 [18] Annex A figure A.54 (without faders).
2. Propagation conditions are set according to clause 4.6.2.1.
3. Message contents are defined in clause 8.1.3.4.3.
4. Cell 1 is the serving cell. Cell 1 is the cell used for connection setup with the power levels set according to TS 36.521-3 [25] clauses C.0 and C.1 for this test. Cell 2 is the neighbour cells. Both cells are on the same RF channel.

8.1.3.4.2 Test procedure
1. Bring the UE to State 3A or 3A-RF according to TS 36.508 [18] clause 4.5.3A or 5.2A.2 with exceptions listed in 7.2A.6, using a value of initial timing advance command TA = 2 in the Random Access Response which indicates an initial timing advance value NTA = 32 Ts. Note that in the remainder of the test the timing advance command TA = 31 which indicates a timing advance adjustment value NTA = 0 Ts.
2. Set the parameters according to Tables 8.1.3.5-1 and 8.1.3.5-2. Propagation conditions are set according to clause 4.6.2.1.
3. The SS adjusts the downlink timing for Cell 1 to a delay of +4 TS, compared to the current value.
4. Wait for 1.6 s to allow for the possibility that the UE makes autonomous timing adjustments.
5. The SS shall transmit an LPP REQUEST CAPABILITIES message.
6. The UE shall transmit an LPP PROVIDE CAPABILITIES message indicating the ECID capabilities supported by the UE in the ECID-ProvideCapabilities IE.
7. The SS shall transmit an LPP REQUEST LOCATION INFORMATION message, including the ECID‑RequestLocationInformation IE. If the UE message at step 6 includes the ackRequested IE set to TRUE, then the SS shall send an acknowledgment in the LPP REQUEST LOCATION INFORMATION message.
8. The UE shall transmit an LPP PROVIDE LOCATION INFORMATION message including the ecid-SignalMeasurementInformation IE.
9. As soon as possible after step 8 the SS shall measure the transmit timing of the UE using the transmitted SRS, relative to the current downlink timing.
10. If the UE message at step 8 includes the ackRequested IE set to TRUE, then the SS shall send a LPP acknowledgment message.
11. The SS shall check the reported value of ue-RxTxTimeDiff in the ecid-SignalMeasurementInformation IE provided by the UE in step 8 and compare it with the value measured in step 9. The SS shall check that the reported value is within the limits specified in table 8.1.3.5-3 compared to the measured value. If the reported value is within the limits the number of successful results for the test point is increased by one. If the reported value is not within the limits, or the UE reports an error in the LPP PROVIDE LOCATION INFORMATION message in step 6, or does not respond at step 8 within the time given by the responseTime IE in the ECID-RequestLocationInformation IE in step 7, then the number of unsuccessful results for the test point test is increased by one.
12. Repeat steps 3-11 until the confidence level according to Annex D.4.3 is achieved.
NOTE: To avoid a large divergence between the sent TA and the set downlink timing, the SS may reset the downlink timing for Cell 1 to its initial value after a certain amount of loops. The loop during the reset does not count for the result statistics.
13. Repeat steps 1-12 for test point 2.
