25.1713GPPFrequency Division Duplex (FDD)Release 17Requirements for support of Assisted Global Positioning System (A-GPS)TS

In case of UE-assisted A-GPS, the measurement parameters are contained in the RRC UE POSITIONING GPS MEASURED RESULTS IE (subclause 10.3.7.93 in 3GPP TS 25.331 [4]). The measurement parameters required for calculating the UE position are:

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

a) "UE GPS timing of cell frames";

b) "GPS TOW msec".

2) Measurement Parameters: 1 to <maxSat>:

a) "Satellite ID (SV PRN)";

b) "Whole GPS chips";

c) "Fractional GPS Chips";

d) "Pseudorange RMS Error".

Additional information required at the system simulator:

1) "UE positioning GPS reference UE position" (subclause 10.3.8.4c in 3GPP TS 25.331 [4]):
Used for initial approximate receiver coordinates.

2) "UE positioning GPS navigation model" (subclause 10.3.7.94 in 3GPP TS 25.331 [4]):
Contains the GPS ephemeris and clock correction parameters as specified in [8]; used for calculating the satellite positions and clock corrections.

3) "UE positioning GPS ionospheric model" (subclause 10.3.7.92 in 3GPP TS 25.331 [4]):
Contains the ionospheric parameters which allow the single frequency user to utilize the ionospheric model as specified in [8] for computation of the ionospheric delay.
