To convert the UE measurement reports in case of UE-assisted mode of A-GANSS into position errors, a transformation between the "measurement domain" (code-phases, etc.) into the "state" domain (position estimate) is necessary. Such a transformation procedure is outlined in the following clauses. The details can be found in [3], [4], [5], [6], [7], [8], [9], [19], [16] and [17].
