9.2.1 FDD-FDD inter-frequency RSTD measurement reporting delay
37.571-13GPPPart 1: Conformance test specificationRelease 16TSUser Equipment (UE) conformance specification for UE positioning
9.2.1.1 Test purpose
To verify that the FDD-FDD inter-frequency RSTD measurement reporting delay meets the requirements in an environment with fading propagation conditions.
9.2.1.2 Test applicability
This test applies to all types of E-UTRA FDD UE release 10 and forward that support inter-frequency RSTD measurements except UE Category 1bis.
9.2.1.3 Minimum conformance requirements
When the physical layer cell identities of neighbour cells together with the OTDOA assistance data are provided, the UE shall be able to detect and measure inter-frequency RSTD, specified in 3GPP TS 36.214 [6], for at least n=16 cells, including the reference cell, within ms as given below:
,
where
is the total time for detecting and measuring at least n cells,
is the largest value of the cell-specific positioning subframe configuration period, defined in 3GPP TS 36.211 [26], among the measured n cells including the reference cell,
is the number of PRS positioning occasions as defined in Table 9.2.1.3-1, where each PRS positioning occasion comprises of (1≤≤6) consecutive downlink positioning subframes defined in 3GPP TS 36.211 [26], and = ms is the measurement time for a single PRS positioning occasion which includes the sampling time and the processing time.

Note 1: When inter-frequency RSTD measurements are performed over the reference cell and neighbour cells, which belong to the FDD inter-frequency carrier frequency f2. Note 2: When inter-frequency RSTD measurements are performed over the reference cell and the neighbour cells, which belong to the serving FDD carrier frequency f1 and the FDD inter-frequency carrier frequency f2 respectively. |
The UE physical layer shall be capable of reporting RSTD for the reference cell and all the neighbour cells i out of at least (n-1) neighbour cells within provided:
≥-6 dB for all Frequency Bands for the reference cell,
≥-13 dB for all Frequency Bands for neighbour cell i,
and conditions apply for all subframes of at least PRS positioning occasions,
PRP 1,2|dBm according to E.3 for a corresponding Band.
is as defined in Section 9.1.1.3.
The time starts from the first subframe of the PRS positioning occasion closest in time after both the OTDOA-RequestLocationInformation message and the OTDOA assistance data in the OTDOA-ProvideAssistanceData message as specified in 3GPP TS 36.355 [4], are delivered to the physical layer of the UE.
This requirement assumes that the measurement report is not delayed by other LPP signalling on the DCCH. This measurement reporting delay excludes a delay uncertainty resulted when inserting the measurement report to the TTI of the uplink DCCH. The delay uncertainty is: 2 x TTIDCCH. This measurement reporting delay excludes any delay caused by no UL resources for UE to send the measurement report.
The normative reference for this requirement is TS 36.133 [23] clause 8.1.2.6.1 and A.8.13.1.

9.2.1.4.2 Test procedure
The test consists of three consecutive time intervals, with duration of T1, T2 and T3 defined in Table 9.2.1.4.1-1. Cell 1 is active in T1, T2 and T3, whilst Cell 2 and Cell 3 are activated only in the beginning of T2. Cell 2 is active until the end of T3, and Cell 3 is active until the end of T2. The beginning of the time interval T2 shall be aligned 5 ms before the first PRS positioning subframe of a positioning occasion in the reference cell, where 5 ms is the necessary test tolerance. Cell 1 transmits PRS only in T2, Cell 2 transmits PRS only in T3, and Cell 3 transmits PRS only in T2.
NOTE: The information on when PRS is muted is conveyed to the UE using PRS muting information in the OTDOA assistance data.
The OTDOA-RequestLocationInformation message and the OTDOA assistance data as defined in clause 9.2.1.4.3 shall be provided to the UE during T1. The last TTI containing the OTDOA-RequestLocationInformation message shall be provided to the UE ΔT ms before the start of T2, where ΔT = 150 ms is the maximum processing time of the OTDOA-RequestLocationInformation message and the OTDOA assistance data.
1. Ensure that the UE is in state Generic RB Established State 3A-RF according to 3GPP TS 36.508 [18] clause 7.2A.3.
2. The SS shall send a RESET UE POSITIONING STORED INFORMATION message.
3. Set the parameters according to Table 9.2.1.5-1. Propagation conditions are set according to clause 4.7.2.2 (ETU30).
4. T1 starts.
5. The SS shall transmit an RRCConnectionReconfiguration message with the DRX configuration and the measurement gap configuration. PDCCHs indicating new transmissions shall be sent continuously until the start of T2 to ensure that the UE would not enter the DRX state before T2.
6. The UE shall transmit RRCConnectionReconfigurationComplete message.
6a. The SS shall transmit an LPP REQUEST CAPABILITIES message.
6b. The UE shall transmit an LPP PROVIDE CAPABILITIES message indicating the OTDOA capabilities supported by the UE in the OTDOA-ProvideCapabilities IE.
7. The SS shall send a LPP PROVIDE ASSISTANCE DATA message, including the OTDOA‑ProvideAssistanceData IE. The position of neighbour Cell 2 in the OTDOA-NeighbourCellInfoList is randomly selected to be in the first 7 elements of the sequence, and the position of neighbour Cell 3 is randomly selected to be in the last 8 elements of the sequence, as described in 3GPP TS 37.571-5 [20], clause 7.2.3. If the UE message at step 6b 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 OTDOA‑RequestLocationInformation IE such that the UE receives the message ΔT ms before the start of T2, where ΔT = 150 ms.
9. When T1 expires, the SS shall switch the power setting from T1 to T2 as specified in Table 9.2.1.5-2.
10. When T2 expires, the SS shall switch the power setting from T2 to T3 as specified in Table 9.2.1.5-2.
11. The UE shall transmit a LPP PROVIDE LOCATION INFORMATION message including the OTDOA‑ProvideLocationInformation IE within the response time (see clause 4.7.3) specified in clause 9.2.1.5. The UE shall perform and report the RSTD measurements for both Cell 2 and Cell 3 with respect to the reference cell in the OTDOA assistance data, Cell 1. If the UE transmits an OTDOA‑ProvideLocationInformation IE including the 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 OTDOA‑ProvideLocationInformation IE with both the rstd fields included within the response time then the number of failure tests is increased by one.
12. If the UE message at step 11 includes the ackRequested IE set to TRUE, the SS shall send a LPP acknowledgement message.
13. Repeat steps 2-12 until the confidence level according to Annex D is achieved. For each iteration, at step 7 change the random position of the Cells 2 and 3 in the OTDOA-NeighbourCellInfoList.

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 and assumed to be constant over subcarriers and time and shall be modelled as AWGN of appropriate power for to be fulfilled. Note 4: If PRS_RA is not “N/A”, , PRS , Io, RSRP and PRP levels have been derived from other parameters and are given for information purpose. If PRS_RA is “N/A”, Io and RSRP levels have been derived from other parameters and are given for information purpose. These are not settable test parameters. Interference conditions shall be applied to all PRS symbols of DL positioning subframes. |
The response time including test tolerance 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 reporting delay plus ΔT, where ΔT = 150 ms, giving a value of 5110 ms. This is rounded up to the next allowed LPP value of 6 seconds. The RSTD measurement reporting delay in the test is derived from the following expression, , where =16 and =16 are the parameters specified in clause 9.2.1.3 and Table 9.2.1.3‑1. This gives the total RSTD reporting delay of 4960 ms for the 15 neighbour cells including Cell 2 and Cell 3 with respect to the reference cell, Cell 1.
The test tolerances are defined in clauses C.1.3 and C4.
The rate of successful tests during repeated tests shall be at least 90% with a confidence level of 95%.
