15.2.4 UE Rx-Tx time difference measurement period for dual 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

15.2.4.1 Test purpose

The purpose of the test is to verify that the UE Rx-Tx measurement period meets the requirements specified in TS 38.133 [50] clause 9.9.4.5 in AWGN propagation condition in FR2 in standalone scenario when dual positioning frequency layers are configured.

15.2.4.2 Test applicability

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

15.2.4.3 Minimum conformance requirements

Same as defined in clause 15.2.1.3.

15.2.4.4 Test description

The supported test configurations in listed in Table 15.2.4.4-1.

Test Configuration

Description

1

120 kHz SSB and PRS SCS, 100 MHz bandwidth, TDD duplex mode

15.2.4.4.1 Initial conditions

Test Environment: Normal, as defined in TS 38.508-1 [45] clause 4.1.

Frequencies to be tested: Low Range for Cell 1 and High Range for Cell2, as defined in TS 38.508-1 [45] clause 4.3.1.

Channel bandwidth to be tested: are specified in Table 15.2.4.4-1.

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 15.2.4.5-1 and Table 15.2.4.5-2.

3. Propagation conditions are set according to clause 4.14.2.

4. Message contents are defined in clause 15.2.4.4.3.

5. There are two cells in the test: PCell (Cell 1) and a neighbour cell (Cell 2). Cell 1 and Cell2 are on different RF channels in FR2.

15.2.4.4.2 Test procedure

Same as defined in clause 15.2.1.4.2.

AWGN

Note 1: The resources for uplink transmission are assigned to the UE prior to the start of time period T2.

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 to be fulfilled.

Note 3: PRS-RSRP and Io levels have been derived from other parameters for information purposes. They are not settable parameters themselves.

Note 4: PRS-RSRP minimum requirements are specified assuming independent interference and noise at each receiver antenna port.

Note 5: Equivalent power received by an antenna with 0 dBi gain at the centre of the quiet zone

Note 6: As observed with 0 dBi gain antenna at the centre of the quiet zone

Note 7: Information about types of UE beam is given in TS 38.133 [50] B.2.1.3, and does not limit UE implementation or test system implementation

The UE Rx-Tx time difference measurement period fulfils the requirements specified in clause 15.2.4.2.

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 81010 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 82 seconds. The RSTD measurement reporting delay in the test is derived from the following expression, the parameters specified in clause 15.2.1.3.

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