14.2.4 NR RSTD measurement period test case for dual positioning frequency layers 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
14.2.4.1 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 dual positioning frequency layers are configured.
14.2.4.2 Test applicability
This test applies to all types of NR UE release 16 onwards that supports DL-TDOA positioning.
14.2.4.3 Minimum conformance requirements
Same as in clause 14.2.1.3.
14.2.4.4 Test description
The supported test configurations in listed in Table 14.2.4.4-1.
Table 14.2.4.4-1: Test Configurations
Test Configuration |
Description |
1 |
120 kHz SSB and PRS SCS, 100 MHz bandwidth, TDD duplex mode |
14.2.4.4.1 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 14.2.4.4-1.
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 14.2.4.5-1, Table 14.2.4.5-2 and Table 14.2.4.5-3.
3. Propagation conditions are set according to clause 4.15.2.
4. Message contents are defined in clause 14.2.4.4.3.
5. In the test there are three synchronous cells: Cell 1, Cell 2 and Cell 3. Cell 1 is the reference as well as the PCell. Cell 2 and Cell 3 are the neighbour cells. All cells are on the 2 RF channels distributed in dual positioning frequency layers.
14.2.4.4.2 Test procedure
Same as in clause 14.2.3.4.2.

Note 1: OCNG shall be used such that active cells (all, except Cell 3 in T3) are fully allocated and a constant total transmitted power spectral density is achieved for all OFDM symbols other than those in the subframes with transmitted PRS. Note 2: The resources for uplink transmission are assigned to the UE prior to the start of time period T2. Note 3: Interference from other cells and noise sources not specified in the test are assumed to be constant over subcarriers and time and shall be modelled as AWGN of appropriate power for to be fulfilled. |
The RSTD measurement time fulfils the requirements specified in clause 14.2.4.3.
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 14.2.4.3 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 82s 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 14.2.4.5.
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%.
