F.2 UE measurement reports

38.1713GPPNRRelease 17Requirements for Support of Assisted Global Navigation Satellite System (A-GNSS)TS

In case of UE-assisted A-GNSS, the measurement parameters are contained in the LPP GNSS-SignalMeasurementInformation IE (clause 6.5.2.6 in TS 36.355 [3]). 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 SS:

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

2) "GNSS-NavigationModel" (clause 6.5.2.2 in TS 36.355 [3]):
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 TS 36.355 [3]):
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 for computation of the ionospheric delay.
