42、on 15.0.0 Release 153.4 Test tolerances The requirements given in the present document make no allowance for measurement uncertainty. The test specification 3GPP TS 34.171 3 defines test tolerances. These test tolerances are individually calculated for each test. The test tolerances are then added t
43、o the limits in the present document to create test limits. The measurement results are compared against the test limits as defined by the shared risk principle. Shared Risk is defined in ETR 273-1-2 7, subclause 6.5. 4 General 4.1 Introduction The present document defines the minimum performance re
44、quirements for both UE based and UE assisted FDD A-GPS terminals. 4.2 Measurement parameters 4.2.1 UE based A-GPS measurement parameters In case of UE-based A-GPS, the measurement parameters are contained in the RRC UE POSITIONING POSITION ESTIMATE INFO IE. The measurement parameter in case of UE-ba
45、sed A-GPS is the horizontal position estimate reported by the UE and expressed in latitude/longitude. 4.2.2 UE assisted A-GPS measurement parameters In case of UE-assisted A-GPS, the measurement parameters are contained in the RRC UE POSITIONING GPS MEASURED RESULTS IE. The measurement parameters in
46、 case of UE-assisted A-GPS are the UE GPS Code Phase measurements, as specified in 3GPP TS 25.302 5 and 3GPP TS 25.215 6. The UE GPS Code Phase measurements are converted into a horizontal position estimate using the procedure detailed in Annex F. 4.3 Response time Max Response Time is defined as th
47、e time starting from the moment that the UE has received the final RRC measurement control message containing reporting criteria different from “No Reporting“ sent before the UE sends the measurement report containing the position estimate or the GPS measured result, and ending when the UE starts se
48、nding the measurement report containing the position estimate or the GPS measured result on the Uu interface. The response times specified for all test cases are Time-to-First-Fix (TTFF) unless otherwise stated, i.e. the UE shall not re-use any information on GPS time, location or other aiding data
49、that was previously acquired or calculated and stored internally in the UE. A dedicated test message RESET UE POSITIONING STORED INFORMATION has been defined in TS 34.109 11 clause 5.4 for the purpose of deleting this information and is detailed in subclause B.1.10. 4.4 Time assistance Time assistance is the provision of GPS time to the UE from the network via RRC messages. Currently two different GPS time assistance methods can be provided by the network. a) Coarse time assistance is always provided by the network and provides current GPS
