15.3.1 UE Rx-Tx time difference measurement accuracy for single positioning frequency layer in FR1 SA
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
15.3.1.1 Test purpose
The purpose of the test is to verify that the UE Rx-Tx time difference measurement accuracy is within the specified limits. This test will verify the requirements in TS 38.133 [50] clause 10.1.25.2. The test is conducted in AWGN propagation condition in FR1 in standalone scenario when single positioning frequency layer is configured.
15.3.1.2 Test applicability
This test applies to all types of NR UE release 16 onwards that supports Multi-RTT positioning.
15.3.1.3 Minimum conformance requirements
The UE Rx-Tx time difference measurement accuracy requirements in this clause shall not apply, if:
NTA_offset defined in Table 7.1.2-2 changes during the UE Rx-Tx measurement period or
if the uplink transmission timing changes during the UE Rx-Tx measurement period due to the network-configured Timing Advance.
The UE Rx-Tx time difference measurement accuracy requirements in this clause shall apply provided that:
– The UE transmits SRS within [-160, 160] msec of at least one DL PRS resource of each of the TRPs in the assistance data.
FFS: whether UE Rx-Tx time difference measurement accuracy requirements in this clause shall also apply if the uplink transmission timing changes during the UE Rx-Tx measurement period due to the autonomous timing adjustment defined in clause 7.1.2.
The UE shall continue and complete a UE Rx-Tx measurement while meeting UE Rx-Tx measurement accuracy requirements defined in this clause when a serving cell change occurs during the UE Rx-Tx measurement provided that the serving cell change does not impact the SRS configuration for the UE Rx-Tx measurement.
Note: The requirements for fading channel in this clause are derived based on TDL-A (30 ns delay spread, 5Hz) and TDL-C (60 ns delay spread, 300 Hz) channel models for FR1 and FR2 respectively.
Editor’s note: In accuracy tables δ is margin and is FFS
The accuracy requirements in Table 10.1.25.2-1 for FR1 are valid under the following conditions:
Conditions defined in clause 7.3 of TS 38.101-1 [18] for reference sensitivity are fulfilled.
PRP|dBm according to Annex B.2.14 for a corresponding Band.

3 |
30 kHz SSB SCS, 40 MHz bandwidth, TDD duplex mode |
Note: The UE is only required to be tested in one of the supported test configurations. |
15.3.1.4.1 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 15.3.1.4-1.
1. Connect the SS and AWGN noise sources to the UE antenna connector or antenna connectors as shown in Annex A, Figure A.13.
2. The general test parameter settings are set up according to Table 15.3.1.5-1.
3. Propagation conditions are set according to clause 4.14.2.
4. Message contents are defined in clause 15.3.1.4.3.
5. There are two cells in the test: PCell (Cell 1) and a neighbour cell (Cell 2). All cells are on the same RF channel in FR1.
15.3.1.4.2 Test procedure
The test consists of a set-up period and a measurement period. Cell 1 and Cell 2 are both active during the complete test. The beginning of the measurement period shall be aligned with the first PRS positioning subframe of a positioning occasion in the reference cell. The NR-Multi-RTT-ProvideAssistanceData and NR-Multi-RTT-RequestLocationInformation as defined in clause 15.3.1.4.3 shall be provided to the UE during the set-up period. The last TTI containing the NR-Multi-RTT-RequestLocationInformation message shall be provided to the UE ΔT ms before the start of the measurement period, where ΔT = 50 ms is the maximum processing time of the NR-Multi-RTT-RequestLocationInformation message and the Multi-RTT assistance data in the UE.
- 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. Note that in the remainder of the test the timing advance command TA = 31 which indicates a timing advance adjustment value NTA = 0 Tc.
2. The SS shall send a RESET UE POSITIONING STORED INFORMATION message.
3. The SS adjusts the downlink timing for Cell 1 to a delay of +8 Tc, 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 RRCReconfiguration message with the SRS configuration.
6. The UE shall transmit RRCReconfigurationComplete message.
7. The SS shall transmit an LPP REQUEST CAPABILITIES message.
8. The UE shall transmit an LPP PROVIDE CAPABILITIES message indicating the Multi-RTT capabilities supported by the UE in the NR-Multi-RTT-ProvideCapabilities IE.
9. The SS shall send a LPP PROVIDE ASSISTANCE DATA message, including the NR-Multi-RTT-ProvideAssistanceData IE.If the UE message at step 8 includes the ackRequested IE set to TRUE, then the SS shall send an acknowledgment in the LPP PROVIDE ASSISTANCE DATA message.
10. The SS shall send a LPP REQUEST LOCATION INFORMATION message, including the NR-Multi-RTT-RequestLocationInformation IE such that the UE receives the message ΔT ms before the start of T2, where ΔT = 50 ms.
11. The UE shall transmit a LPP PROVIDE LOCATION INFORMATION message including the NR-Multi-RTT-ProvideLocationInformation IE.
12. As soon as possible after step 11 the SS shall measure the transmit timing of the UE using the transmitted SRS, relative to the current downlink timing.
13. If the UE message at step 11 includes the ackRequested IE set to TRUE, the SS shall send a LPP acknowledgement message.
14. The SS shall check the reported value of nr-UE-RxTxTimeDiff in the NR-Multi-RTT-SignalMeasurementInformation IE provided by the UE in step 11 and compare it with the value measured in step 12. The SS shall check that the reported value is within the limits specified in table 15.3.1.5-2 compared to the measured value. If the reported value is within the limits the number of successful results 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 11, or does not respond at step 11 within the time given by the time IE in the CommonIEsRequestLocationInformation IE in step 10, then the number of unsuccessful results for is increased by one.
15. Repeat steps 1-14 until the confidence level according to Annex D is achieved.
16. Repeat step 1-15 for the other sub-test defined in Table 15.3.1.4-1 as appropriate.
If all (applicable) sub-tests pass, the whole test passes. If one (applicable) sub-test fails, the whole test fails.
