14.2.2 NR RSTD measurement period test case for dual positioning frequency layer in FR1 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 not yet determined:

– The TT analysis is FFS.- The test requirements contain values in [.].

14.2.2.1 Test purpose

The purpose of the test is to verify that the RSTD measurement meets the requirements specified in TS 38.133 [50] Clause 9.9.2 in an environment with AWGN propagation conditions in FR1 in standalone scenario when dual positioning frequency layer is configured.

14.2.2.2 Test applicability

This test applies to all types of NR UE release 16 onwards that supports DL-TDOA positioning.

14.2.2.3 Minimum conformance requirements

Same as in clause 14.2.1.3.

14.2.2.4 Test description

14.2.2.4.1 Initial conditions

The test is defined with three possible Test Configurations. In the case that the UE supports more than one of these Test Configurations, then the UE is only required to be tested in one of the Test Configurations, chosen by the UE. The defined Test Configurations are specified in Table 14.2.2.4.1-1.

2. The general test parameter settings are set up according to Table 14.2.2.5-1, Table 14.2.2.5-2 and Table 14.2.2.5-3.

3. Propagation conditions are set according to clause 4.15.2.

4. Message contents are defined in clause 14.2.4.1.3.

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. Cell 1 and Cell 2 are on RF channel #1 in FR1, Cell 3 on RF channel #2 on FR1.

14.2.2.4.2 Test procedure

Same as clause 14.2.1.4.2.

14.2.2.4.3 Message contents

Same as 14.2.4.1.3 except that Table 14.2.2.4.3-1 replaces 14.2.4.1.3-5 and Table 14.2.2.4.3-2 replaces 14.2.4.1.3-6.

Propagation Condition

AWGN

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 14.2.2.3.

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 14.2.2.3 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 13+TT s. The response time is equal to the LPP time IE value plus the test tolerance. The LPP time IE value is derived from the RSTD measurement period plus ΔT, where ΔT = 50 ms, giving a value of 12310 ms assuming durationOfPRS-ProcessingSymbolsInEveryTms is 1280 ms. This is rounded up to the next allowed LPP value of 13 seconds. The RSTD measurement reporting delay in the test is derived from the following expression, , the parameters specified in clause 14.2.1.5.

The test tolerances are defined in clauses C.1.6, C 2.5 and C4.

The rate of successful tests during repeated tests shall be at least 90% with a confidence level of 95%.
