6.1 GNSS Scenarios and Assistance Data for Assisted GNSS signalling tests
37.571-53GPPPart 5: Test scenarios and assistance dataRelease 16TSUser Equipment (UE) conformance specification for UE positioning
6.1.1 General
This subclause defines the GNSS scenario and the associated assistance data that shall be used where required for UTRA, E-UTRA and NR Assisted GNSS signalling tests defined in TS 37.571-2 [7] subclauses 6.2.1 to 6.2.3 and subclauses 7 and 9.
In all cases the Assistance Data is given in the two necessary formats, RRC format for TS 37.571-2 [7] subclauses 6.2.1 to 6.2.3 and LPP format for TS 37.571-2 [7] subclauses 7 and 9. Other information is also given separately for TS 37.571-2 [7] subclauses 6.2.1 to 6.2.3 and subclauses 7 and 9 where it differs between the subclauses.
The satellite simulator shall generate all the UE supported GNSS satellite signals defined in subclause 6.1.2 and/or shall provide assistance data dependent on the UE capabilities defined in subclause 6.1.3. Note that some tests require assistance data to be provided even though satellite signals are not required.
The A-GNSS signalling test cases may include several sub-test cases dependent on the GNSS supported by the UE. Each sub-test case is identified by a Sub-Test Case Number as defined below. In some cases the detailed assistance data content defined in subclause 6.1.3 depends on the particular sub-test case.

6.1.3.2 Assistance Data values for TS 37.571-2 subclauses 6.2.1 to 6.2.3
Assistance data that is marked as “time varying” and the GPS TOW msec or GANSS TOD field are created and used in 1 second increments.
The accuracy of the GPS TOW msec or GANSS TOD and assistance data that is marked as “time varying” in the provided assistance data shall be within +/- 2 s relative to the GNSS time in the system simulator. In the case that assistance data is required but satellite signals are not required then this clause does not apply.
Assistance data Information Elements and fields that are not specified shall not be used.

This “current GPS TOW msec” is then also used to determine the value of any other Information Elements marked as “Time varying” in subclause 6.1.3.2.
