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 in draft status.
– The test requirements need to be aligned with latest TS 38.133.
14.2.1.1 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 single positioning frequency layer is configured.
14.2.1.2 Test applicability
This test applies to all types of NR UE release 16 onwards that supports DL-TDOA positioning.
14.2.1.3 Minimum conformance requirements
When physical layer receives last of NR-TDOA-ProvideAssistanceData message and NR-TDOA-RequestLocationInformation message from LMF via LPP [49], the UE shall be able to measure and report multiple (up to the UE capability specified in TS 38.133 [50] Clause 9.9.2.3) DL RSTD measurements, during the measurement period defined as:
Where ,
is the index of positioning frequency layer,
is total number of positioning frequency layers, and
is the periodicity of the PRS RSTD measurement in positioning frequency layer i
is the measurement period for PRS RSTD measurement in positioning frequency layer i as specified below:
,
where:
is the UE Rx beam sweeping factor. In FR1, = 1; and in FR2, = 8.
is the carrier-specific scaling factor for NR PRS-based positioning measurements in positioning frequency layer i as defined in TS 38.133[50] clause 9.1.5.2.
is the maximum number of DL PRS resources in positioning frequency layer i configured in a slot.
is the time duration of available PRS to be measured in the positioning frequency layer i, and is calculated in the same way as PRS duration K defined in clause 5.1.6.5 of TS 38.214 [56].
is the number of PRS RSTD samples and = 4.
is the measurement duration for the last PRS RSTD sample, including the sampling time and processing time, = + ,
is the periodicity of the PRS RSTD measurement in positioning frequency layer i defined as:
=
Where,
corresponds to durationOfPRS-ProcessingSymbolsInEveryTms in TS 37.355 [49],
, the least common multiple between and .
is the repetition periodicity of the measurement gap applicable for measurement in the PRS frequency layer i.
is the periodicity of DL PRS resource with muting on positioning frequency layer i.
If more than one PRS periodicities are configured in positioning frequency layer i, the least common multiple of PRS periodicities among all DL PRS resource sets in the positioning frequency layer is used to derive the measurement period of that positioning frequency layer i. Where,
, is the PRS periodicity with muting per PRS resource,
is the periodicity of PRS resource sets given by the higher-layer parameter DL-PRS-Periodicity.
is the scaling factor considering PRS resource muting. If bitmap for higher-layer parameter DL-PRS-MutingPattern is provided, and , then ; otherwise, if bitmap is not provided or , then .
is the muting repetition factor given by the higher-layer parameter DL-PRS-MutingBitRepetitionFactor, and L is the size of the bitmap .
- Note: For the purpose of calculating TPRS,i, only the PRS resources fully or partially covered by the MG are considered.
is UE capability combination per band where N is a duration of DL PRS symbols in ms corresponding to durationOfPRS-ProcessingSysmbols in TS 37.355 [49] processed every T ms corresponding to durationOfPRS-ProcessingSymbolsInEveryTms in TS 37.355 [49] for a given maximum bandwidth supported by UE corresponding to supportedBandwidthPRS in TS 37.355 [49].
is UE capability for number of DL PRS resources that it can process in a slot as indicated by maxNumOfDL-PRS-ResProcessedPerSlot specified in TS 37.355 [49].
The time starts from the first MG instance aligned with a DL PRS resource(s) of positioning frequency layer i closest in time after both the NR-TDOA-ProvideAssistanceData message and NR-TDOA-RequestLocationInformation message are delivered from LMF to the physical layer of UE via LPP.
14.2.1.4 Test description
14.2.1.4.1 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 14.2.1.4.1-1.
Table 14.2.1.4.1-1: Test Configurations

Test Environment: Normal, as defined in TS 38.508-1 [45] clause 4.1.
Frequencies to be tested: Mid, as defined in TS 38.508-1 [45] clause 4.3.1.
Channel bandwidth to be tested: are specified in Table 14.2.1.4-1.
1. Connect the SS and AWGN noise sources to the UE antenna connector or antenna connectors as shown in Annex A, Figure A.12.
2. The general test parameter settings are set up according to Table 14.2.1.5-1, Table 14.2.1.5-2 and Table 14.2.1.5-3.
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. All 3 cells are on the same RF channel in FR1
14.2.1.4.2 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 #0 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 14.2.1.5-1, Table 14.2.1.5-2 and Table 14.2.1.5-3. 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 14.2.1.5-2 and Table 14.2.1.5-3.
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 14.2.1.4-1 until the confidence level according to Annex D is achieved.

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 slots 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. Note 4: SSB RP and Io levels have been derived from other parameters and are given for information purpose. These are not settable test parameters. |
The RSTD measurement time fulfils the requirements specified in clause 14.2.1.3.
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 14.2.1.3 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 6.3 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 5590 ms assuming durationOfPRS-ProcessingSymbolsInEveryTms is 1280 ms. This is rounded up to the next allowed LPP value of 7 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%.
