9.4.16 E-UTRAN FDD inter-frequency RSTD measurement period test case in CE Mode B with longer PRS occasions

37.571-13GPPPart 1: Conformance test specificationRelease 16TSUser Equipment (UE) conformance specification for UE positioning

9.4.16.1 Test purpose

To verify that the RSTD measurement reporting delay with longer PRS occasions for UE Category M1 and M2 meets the performance requirements in normal coverage mode in an environment with fading propagation conditions.

9.4.16.2 Test applicability

This test applies to E-UTRA FDD UE Category M1 and M2 release 15 and forward that supports UE-assisted OTDOA, CE Mode B, inter-frequency RSTD measurements and dense PRS configuration or additional PRS configuration. Test 2 is applicable only to UE Category M2.

9.4.16.3 Minimum conformance requirements

Same as in clause 9.4.4.1.3

The normative reference for this requirement is TS 36.133 [23] clause 8.13.3.7.1, 8.16.3.2.1 and A.8.13.12.

9.4.16.4.1 Initial conditions

Same as in clause 9.4.13.4.1 but replacing Table 9.4.13.4.1-1 with Table 9.4.16.4.1-1.

Cell 1

Reference cell is the cell in the OTDOA assistance data with respect to which the RSTD measurement is defined, as specified in 3GPP TS 36.214 [6] and 3GPP TS 36.355 [4]. The reference cell is the serving cell in this test case.

Neighbour cells

Cell 2 and Cell 3

Cell 2 and Cell 3 appear at random places in the neighbour cell list in the OTDOA assistance data, but Cell 2 always appears in the first half of the list, whilst Cell 3 appears in the second half of the list.

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 9.3.16.4.3-5 and TS 37.571-5 [20], clause 7.2.5.

Note 2: Parameters “PRS Transmission Bandwidth”, “PRS configuration index”, “Number of consecutive downlink positioning subframes”, “Physical cell ID PCI”, “CP length”, and “PRS muting info” are settable parameters and also parameters signalled in LPP. The values to be used for “Physical cell ID PCI” are as follows: Cell 1: 0, Cell 2: 6, Cell 3: 12. For all the values to be used in LPP see Table 9.3.16.4.3-5 and TS 37.571-5 [20], clause 7.2.5.

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 9.3.16.4.1.

Note 4: If the PRS transmission bandwidth is larger than the UE RF bandwidth, the UE is measuring RSTD within its RF bandwidth.
