9.1.3A FDD RSTD Measurement Accuracy for UE Category 1bis

37.571-13GPPPart 1: Conformance test specificationTSUniversal Terrestrial Radio Access (UTRA) and Evolved UTRA (E-UTRA) and Evolved Packet Core (EPC)User Equipment (UE) conformance specification for UE positioning

9.1.3A.1 Test purpose

To verify that the RSTD FDD intra-frequency measurement accuracy is within the specified limits.

9.1.3A.2 Test applicability

This test applies to E-UTRA FDD UE Category 1bis release 13 and forward that supports UE-assisted OTDOA.

9.1.3A.3 Minimum conformance requirements

Same as 9.1.3.3

The normative reference for this requirement is TS 36.133 [23] clause 9.1.10.5 and A.9.8.1.2A.

9.1.3A.4 Test description
9.1.3A.4.1 Initial conditions

Same as 9.1.3.4.1 with the following exceptions:

1. Connect the SS, faders and AWGN noise sources to the UE antenna connector or antenna connectors as shown in Annex A, Figure A.3, using only the main Tx/Rx path.

2. The general test parameter settings are set up according to Table 9.1.3A.4.1-1

Derived according to the RSTD measurement requirements specified in Section 9.1.1A.3

NOTE 1: Parameters “Expected RSTD” and “Expected RSTD uncertainty for all neighbour cells” are not settable parameters. These are parameters signalled in LPP only. For the values to be used in LPP see Table 9.1.3.4.3-4 and TS 37.571-5 [20], clause 7.2.2.

NOTE 2: Parameters “PRS Transmission Bandwidth”, “PRS configuration index”, “Number of consecutive positioning downlink subframes”, “prs-MutingInfo”, “Cell ID” and “CP length” are settable parameters and also parameters signalled in LPP. The values to be used for “Cell ID” are as follows: Cell 1: 0, Cell 2: Test 1: 6, Test 2: 7, Test 3: 6, Test 4: 9. For all the values to be used in LPP see Table 9.1.3.4.3-4 and TS 37.571-5 [20], clause 7.2.2.

NOTE 3: The parameter “Radio frame receive time offset between the cells at the UE antenna connector” is not a settable parameter but is used to set the “true RSTD” values in step 6 of clause 9.1.3.4.1.

NOTE 4: The parameter “” is not a settable parameter but is used to set the LPP “time” value in Table 9.1.3A.4.3-2. The value of the LPP time IE is set to + T ms, where T = 150 ms, giving a value of 5270 ms. This is rounded up to the next allowed LPP value of 6 seconds.
