14.2.3 NR RSTD measurement period test case for single positioning frequency layer in FR2 SA
37.571-13GPPPart 1: Conformance test specificationRelease 16TSUser Equipment (UE) conformance specification for UE positioning
Editor’s note: This test case is incomplete. The following aspects are either missing or TBD
– Test tolerance are not added in and analysis is missing.
14.2.3.1 Test purpose
The purpose of the test is to verify that the RSTD measurement meets the accuracy requirements specified in TS 38.133 [50] clause 9.9.2 in an environment with AWGN propagation conditions. The test is conducted in AWGN propagation condition in FR2 in standalone scenario when single positioning frequency layer is configured.
14.2.3.2 Test applicability
This test applies to all types of NR UE release 16 onwards that supports DL-TDOA positioning.
14.2.3.3 Minimum conformance requirements
Same as in clause 14.2.1.3.
14.2.3.4 Test description
The supported test configurations in listed in Table 14.2.3.4-1Table 14.2.3.4-1: Test Configurations
|
Test Configuration |
Description |
|
1 |
120 kHz SSB and PRS SCS, 100 MHz bandwidth, TDD duplex mode |
14.2.3.4.1 Initial conditions
Test Environment: Normal, as defined in TS 38.508-1 [45] clause 4.1.
Frequencies to be tested: Mid Range, as defined in TS 38.508-1 [45] clause 4.3.1.
Channel bandwidth to be tested: are specified in Table 14.2.3.4-1.
1. Connect the SS and AWGN noise sources to the UE antenna connector or antenna connectors as shown in Annex A, Figure A.14.
2. The general test parameter settings are set up according to Table 14.2.3.5-1, Table 14.2.3.5-2 and Table 14.2.3.5-3.
3. Propagation conditions are set according to clause 4.15.2.
4. Message contents are defined in clause 14.2.3.4.3.
5. In the test there are three synchronous cells: Cell 1, Cell 2 and Cell 3. Cell 1 is the RSTD reference as well as the PCell. Cell 2 and Cell 3 are the neighbour cells. All 3 cells are on the same RF channel in FR2.
14.2.3.4.2 Test procedure
The test consists of two consecutive time intervals, with duration of T1 and T2. Cell 1 is active in T1 and T2, whilst Cell 2 and Cell 3 are activated only in the beginning of T2. The beginning of the time interval T2 shall be aligned with the first PRS positioning subframe of a positioning occasion in the reference cell.
The NR-DL-TDOA-ProvideAssistanceData as defined in TS 37.355 [49] clause 6.5.10.1 shall be provided to the UE during T1. The last TTI containing the NR-DL-TDOA-ProvideAssistanceData shall be provided to the UE ΔT ms before the start of T2, where ΔT = 50 ms is the maximum processing time of the DL-TDOA assistance data and location information request.
The UE is configured with measurement gap pattern ID # 24 or #13 before T2.
- Ensure the UE is in State RRC_CONNECTED with generic procedure parameters Connectivity NR, Connected without release On, according to TS 38.508-1 [45] clause 4.5.
2. The SS shall send a RESET UE POSITIONING STORED INFORMATION message.
3. Set the parameters according to Table 14.2.3.5-1, Table 14.2.3.5-2 and Table 14.2.3.5-3. Propagation conditions are set according to clause 4.15.2.
4. T1 starts.
5. The SS shall transmit an LPP REQUEST CAPABILITIES message.
6. The UE shall transmit an LPP PROVIDE CAPABILITIES message indicating the DL-TDOA capabilities supported by the UE in the NR-DL-TDOA-ProvideCapabilities IE.
7. The SS shall send a LPP PROVIDE ASSISTANCE DATA message, including the NR-DL-TDOA-ProvideAssistanceData IE. The position of neighbour Cell 2 and the position of neighbour Cell 3 are described in 3GPP TS 37.571-5 [20]. If the UE message at step 6 includes the ackRequested IE set to TRUE, then the SS shall send an acknowledgment in the LPP PROVIDE ASSISTANCE DATA message.
8. The SS shall send a LPP REQUEST LOCATION INFORMATION message, including the NR-DL-TDOA-RequestLocationInformation IE such that the UE receives the message ΔT ms before the start of T2, where ΔT = 50 ms.
9. When T1 expires, the SS shall switch the power setting from T1 to T2 as specified in Table 14.2.3.5-2 and Table 14.2.3.5-3.
10. The UE shall transmit a LPP PROVIDE LOCATION INFORMATION message including the NR-DL-TDOA-ProvideLocationInformation IE within the response time (see clause 4.15.3). The UE shall perform and report the RSTD measurements for both Cell 2 and Cell 3 with respect to the reference cell in the DL-TDOA assistance data, Cell 1. If the UE transmits an NR-DL-TDOA-ProvideLocationInformation IE including the nr-RSTD field for both Cell 2 and Cell 3 within the response time then the number of successful tests is increased by one. If the UE fails to report the NR-DL-TDOA-ProvideLocationInformation IE with both the nr-RSTD fields included within the response time then the number of failure tests is increased by one.
11. If the UE message at step 10 includes the ackRequested IE set to TRUE, the SS shall send a LPP acknowledgement message.
12. Repeat steps 2-11 in Tables 14.2.3.4-1 until the confidence level according to Annex D is achieved.

Note 3
to be fulfilled.The RSTD measurement time fulfils the requirements specified in clause 14.2.3.3.
The UE shall perform and report the RSTD measurements for Cell 2 and Cell 3 with respect to the reference cell in the DL-TDOA assistance data, Cell 1, within the time duration specified in clause 14.2.3.3 starting from the beginning of time interval T2.
The rate of the correct events for each neighbour cell observed during repeated tests shall be at least 90%, where the reported RSTD measurement for each correct event shall be within the RSTD reporting range specified in TS 38.133[50] Clause 10.1.23.3, i.e., between RSTD_0000000 and RSTD_1970049.
The response time is 42s plus test tolerance. The response time is equal to the LPP time IE value plus the test tolerance. The LPP time IE value is derived from the Rx-Tx measurement period plus ΔT, where ΔT = 50 ms, giving a value of 41280 ms assuming durationOfPRS-ProcessingSymbols-r16 is 0.125 ms and durationOfPRS-ProcessingSymbolsInEveryTms is 1280 ms. This is rounded up to the next allowed LPP value of 42 seconds. The RSTD measurement reporting delay in the test is derived from the following expression, , the parameters specified in clause 14.2.3.5.
The test tolerances are defined in clauses C.1.6 and C.2.5.
The rate of successful tests during repeated tests shall be at least 90% with a confidence level of 95%.
