4 Default Conditions for UTRAN

37.571-23GPPPart 2: Protocol conformanceRelease 16TSUser Equipment (UE) conformance specification for UE positioning

4.1 Default system information

Default system information, as specified in 3GPP TS 34.108 [16] subclause 6.1, is broadcasted for the A-GPS test cases in subclause 6.1. For the A-GNSS test cases in subclause 6.2, the default system information, as specified in 3GPP
TS 36.508 [8], is broadcasted. SIB15/SIB15.x are not broadcasted unless otherwise stated in the specific test cases.

4.2 Simulated A-GPS and A-GNSS environment

During A-GPS and A-GNSS tests, where required the SS shall generate satellite signals that are of a sufficient number and strength not to prevent the UE from responding to a positioning request with a valid measurement response. Any assistance data provided during these tests shall be consistent with the satellite signals generated during these tests. Note that some tests require assistance data to be provided even though satellite signals are not required.

It is considered that six satellite signals with the level of the simulated satellites all at -125 dBm ± 6 dB should be suitable, however this does not imply any conformance requirements on the UE.

Suitable GPS and GNSS scenarios together with associated assistance data are defined in TS 37.571-5 [12] subclause 5.1 and 6.1, respectively.

The accuracy of the GPS time-of-week and/or GANSS time-of-day in the provided assistance data shall be within ± 2 seconds relative to the GPS and/or GANSS 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.

During A-GNSS signalling tests where satellite signals are required, the SS shall generate all the UE supported GNSS satellite signals.

4.2.1 A-GNSS sub-test cases

The A-GNSS signalling test cases in subclause 6.2 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 in the Table below. The detailed assistance data depend on the particular sub-test case as defined in subclause 4.4.

Table 4.2.1-1: Sub-Test Case Number Definition for UTRA

NOTE 1: "A-GPS" includes Modernized GPS if supported by the UE.

4.3 A-GPS assistance data sets

This subclause defines the assistance data sets supplied by the SS in A-GPS test cases specified in subclause 6.1.

Throughout this subclause, "adequate assistance data" means the assistance data used in test cases where it is expected that a UE supporting A-GPS will be able to perform the requested positioning operation using the supplied assistance data, and "inadequate assistance data" is the assistance data used in test cases that expect that the UE will be unable to perform the requested operation. The values of all the fields in all cases are defined in TS 37.571-5 [12] subclause 5.1.3.

If the UE requests the GPS navigation model or the GANSS navigation model Model-1, Model-2, Model-3 or Model 6 then the SS provides navigation model satellite information for at most three satellites in any one MEASUREMENT CONTROL or ASSISTANCE DATA DELIVERY message; additional satellites are sent in subsequent MEASUREMENT CONTROL or ASSISTANCE DATA DELIVERY messages.

If the UE requests the GPS or GANSS almanac then the SS provides almanac information spread across at least two MEASUREMENT CONTROL or ASSISTANCE DATA DELIVERY messages.

If the UE requests both navigation model and almanac then the SS provides them in different MEASUREMENT CONTROL or ASSISTANCE DATA DELIVERY messages.
