10.5.4.2 Test procedure

The test case includes two tests. Test 1 is designed for the scenario where the UE receives OTDOA assistance data with cells only on SCC2, and the UE is expected to report RSTD measurements performed on SCC2 only. Test 2 is designed for the scenario where the UE receives OTDOA assistance data with cells on PCC, SCC1 and SCC2, and the UE is expected to report RSTD measurements performed on PCC, SCC1 and SCC2.

Each test consists of three consecutive time intervals, with duration of T1, T2 and T3. Cell 1 is active in T1, T2 and T3, Cell 2 is active only in T2 and T3, Cell 3 is active only during T2 and T3, and Cell 4 is active only during 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 OTDOA assistance data reference cell, where 5 ms is the necessary test tolerance. Cell 1 transmits PRS in T2, Cell 2 transmits PRS only in T3, Cell 3 transmits PRS only in T3, and Cell 4 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 10.5.4.3 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. Configure Cell 2 on SCC1 and Cell 3 and Cell 4 on SCC2 according to TS 36.521-3 [25] Annex C.0 and C.1 for all downlink physical channels.

3. The SS shall configure the SCells (Cell 2 and Cell 3) on the SCCs as per TS 36.508 [18] clause 5.2A.4.

4. The SS activates the SCells (Cell 2 and Cell 3) by sending the Activation/Deactivation MAC control element according to TS 36.321 [34] clauses 5.13 and 6.1.3.8. Wait for at least 2 seconds as per TS 36.133 [23] clause 8.3.3.2.

5. The SS shall send a RESET UE POSITIONING STORED INFORMATION message.

6. Set the parameters according to Table 10.5.5-1. Propagation conditions are set according to clause 4.7.2.2 (ETU30).

7. T1 starts.

8. The SS shall transmit an RRCConnectionReconfiguration message with the DRX 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.

9. The UE shall transmit RRCConnectionReconfigurationComplete message.

9a. The SS shall transmit an LPP REQUEST CAPABILITIES message.

9b. The UE shall transmit an LPP PROVIDE CAPABILITIES message indicating the OTDOA capabilities supported by the UE in the OTDOA-ProvideCapabilities IE.

10. The SS shall send a LPP PROVIDE ASSISTANCE DATA message, including the OTDOA‑ProvideAssistanceData IE. The position of neighbour Cell 4 in the OTDOA-NeighbourCellInfoList is randomly selected to be in the last 8 elements of the sequence for Test 1 and in the 7 elements of the relevant sequence for Test 2, and the position of Cell 1 and the position of Cell 2 are randomly selected to be in the 4 elements of the relevant sequence for Test 2, as described in 3GPP TS 37.571-5 [20], clause 7.3.2. If the UE message at step 9b includes the ackRequested IE set to TRUE, then the SS shall send an acknowledgment in the LPP PROVIDE ASSISTANCE DATA message.

11. 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.

12. When T1 expires, the SS shall switch the power setting from T1 to T2 as specified in Table 10.5.5-2.

13. When T2 expires, the SS shall switch the power setting from T2 to T3 as specified in Table 10.5.5-2.

14. 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 10.5.5.

For Test 1 the UE shall perform and report the RSTD measurement for Cell 4 with respect to the reference cell in the OTDOA assistance data, Cell 3. If the UE transmits an OTDOA‑ProvideLocationInformation IE including the rstd field for Cell 4 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 the rstd field included within the response time then the number of failure tests is increased by one.

For Test 2 the UE shall perform and report the RSTD measurements for Cell 1 with respect to the reference cell in the OTDOA assistance data, Cell 3 and also Cell 2 with respect to the reference cell in the OTDOA assistance data, Cell 3 and also Cell 4 with respect to the reference cell in the OTDOA assistance data, Cell 3. If the UE transmits an OTDOA‑ProvideLocationInformation IE including the rstd field for Cell 1 (with respect to Cell 3) and Cell 2 (with respect to Cell 3) and Cell 4 (with respect to 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 the three rstd fields included within the response time then the number of failure tests is increased by one.

15. If the UE message at step 14 includes the ackRequested IE set to TRUE, the SS shall send a LPP acknowledgement message.

16. Repeat steps 5-15 until the confidence level according to Annex D is achieved. For each iteration, at step 10 change the random positions of Cell 4 and Cell 1(for Test 2 only) and Cell 2(for Test 2 only) in the relevant sequence in the OTDOA-NeighbourCellInfoList.

17. Repeat from clause 10.5.4.1 for Test 2.

Propagation Condition

ETU30

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.

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 3.3 s for Test 1 and 6.3 s for Test 2. 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 2710 ms for Test 1 and 5110ms for Test 2. This is rounded up to the next allowed LPP value of 3 seconds for Test 1 and 6 seconds for Test 2.

The RSTD measurement reporting delay in the tests are derived from the following expression, , where =8 and =16 for Test 1, and =16 and =16 for Test 2 are the parameters specified in clause 10.5.3.1 for Test 1 and clause 10.5.3.2 for Test 2.

This gives the total RSTD reporting delay of 2560 ms for Test 1 for the 15 neighbour cells including Cell 4 with respect to the reference cell, Cell 3.

This gives the total RSTD reporting delay of 4960 ms for Test 2 for the 15 neighbour cells including Cell 1, Cell 2 and Cell 4 with respect to the reference cell, Cell 3.

The test tolerances are defined in clauses C.1.3 and C.4.

For the overall test to pass, the rate of successful tests during repeated tests in both Test 1 and Test 2 shall be more than 90% with a confidence level of 95%.
