1> if the IE "Positioning Methods" in IE "UE positioning reporting quantity" has been assigned to value "GPS" and
the IE "GANSS Positioning Methods"is present:
2> if there were not enough GANSS satellites to be received:
3> set IE "Error reason" to "Not Enough GANSS Satellites".
2> if some GANSS assistance data was missing:
3> set IE "Error reason" to "Assistance Data Missing"; and
3> if the IE "Additional Assistance Data Request" included in the IE "UE positioning reporting quantity"
stored in the variable MEASUREMENT_IDENTITY is set to TRUE:
4> include the IE "GANSS Additional Assistance Data Request".
3> if the IE "Additional Assistance Data Request" included in the IE "UE positioning reporting quantity"
stored in the variable MEASUREMENT_IDENTITY is set to FALSE:
4> not include the IE "GANSS Additional Assistance Data Request", and use the assistance data
available for doing a positioning estimate.
2> if the UE was not able to read the SFN of the reference cell included in the IE "UE positioning GANSS
reference time":
3> set IE "Error reason" to "Reference Cell Not Serving Cell".
2> if the UE was not able to measure the requested GANSS timing of cell frames measurement:
3> set IE "Error reason" to "Not Accomplished GANSS Timing Of Cell Frames".
1> if none of the conditions above are fulfilled:
2> set IE "Error reason" to "Undefined Error".
The UE shall not set the IE "Error reason" to "Request Denied By User" or "Not Processed and Timeout".

8.6.7.19.7 UE positioning GANSS assistance data
The UE may receive GANSS assistance data in System Information Block types 15bis, 15.1bis, 15.1ter, 15.2bis,
15.2ter, 15.3bis, 15.6, 15.7 or 15.8 or in the ASSISTANCE DATA DELIVERY message, or in the MEASUREMENT
CONTROL message. IE "UE positioning GANSS assistance data" is divided into a common part which is applicable to
any GNSS and a generic part which contains assistance data separately for each supported GNSS.
8.6.7.19.7.1 UE positioning GANSS reference measurement information
If the IE "UE positioning GANSS reference measurement information" is included, the UE shall:
1> update the variable UE_POSITIONING_GANSS_DATA as follows:
2> for each GANSS the IE "UE positioning GANSS reference measurement information" is included:
3> delete all information currently stored in the IE "UE positioning GANSS reference measurement
information" in the variable UE_POSITIONING_GANSS_DATA;
3> store the received information in the IE "UE positioning GANSS reference measurement information" in
the variable UE_POSITIONING_GANSS_DATA.
1> for each GANSS:
2> if the IE "Confidence" is included:
