B.4 E-UTRAN and NR UE measurement reports

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

In case of E-UTRAN and NR UE-assisted A-GNSS, the measurement parameters are contained in the LPP GNSS- SignalMeasurementInformation IE (clause 6.5.2.6 in 3GPP TS 36.355 [4] and 3GPP TS 37.355 [49]). The measurement parameters required for calculating the UE position are:

1) Reference Time: The UE has two choices for the Reference Time:

a) "networkTime";

b) "gnss-TOD-msec".

2) Measurement Parameters for each GNSS and GNSS signal: 1 to 64:

a) " svID";

b) "codePhase";

c) "integerCodePhase";

d) "codePhaseRMSError".

Additional information required at the system simulator:

1) "GNSS-ReferenceLocation" (clause 6.5.2.2 in 3GPP TS 36.355 [4] and 3GPP TS 37.355 [49]):
Used for initial approximate receiver coordinates.

2) "GNSS-NavigationModel" (clause 6.5.2.2 in 3GPP TS 36.355 [4] and 3GPP TS 37.355 [49]):
Contains the GNSS ephemeris and clock correction parameters as specified in the relevant ICD of each supported GNSS; used for calculating the satellite positions and clock corrections.

3) "GNSS-IonosphericModel" (clause 6.5.2.2 in 3GPP TS 36.355 [4] and 3GPP TS 37.355 [49]):
Contains the ionospheric parameters which allow the single frequency user to utilize the ionospheric model as specified in the relevant ICD of each supported GNSS [8], [14], [15] and [37] for computation of the ionospheric delay.
