34、t uncertainty. The test specification 3GPP TS 37.571 -1 9 will define test tolerances. These test tolerances are individually calculated for each test. The test tolerances are then added to the limits in the present document to create test limits. The measurement results are compared against the tes
35、t limits as defined by the shared risk principle. Shared Risk is defined in ETSI TR 102 273-1-2 2, subclause 6.5. 4 General 4.1 Introduction The present document defines the minimum performance requirements for UEs that support RAT Independent positioning technologies. 4.2 MBS Measurements 4.2.1 Gen
36、eral Clause 4.2 describes the measurements performed by the UE for MBS positioning. 4.2.2 MBS measurement parameters The measurement parameters are the MBS code phase measurements contained in the TBS-MeasurementInformation IE provided in the LPP message of type PROVIDE LOCATION INFORMATION 3 for LT
37、E, and the UE Positioning AddPos measured results IE in the MEASUREMENT REPORT message for UTRA 6. 4.2.3 MBS Measurement time For LTE, MBS measurement time is defined as the time starting from the moment that the UE has received the LPP message of type REQUEST LOCATION INFORMATION, and ending when t
38、he UE starts sending the LPP message of type PROVIDE LOCATION INFORMATION on the Uu interface. The response times specified for all test cases are based on new measurements unless otherwise stated, i.e. the UE shall not re use any information on measurements or other aiding data that was previously
39、acquired or calculated and stored internally in the UE. A dedicated test message RESET UE POSITIONING STORED INFORMATION has been defined in TS 36.509 4 clause 6.9 for the purpose of deleting this information. ETSI ETSI TS 137 171 V13.1.0 (2017-01)73GPP TS 37.171 version 13.1.0 Release 13For UTRA, M
40、BS measurement time is defined as the 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 MBS measured results, and ending when the
41、UE starts sending the measurement report containing the measured result on the Uu interface. The response times specified for all test cases are based on new measurements unless otherwise stated, i.e. the UE shall not re use any information on measurements or other aiding data that was previously ac
42、quired or calculated and stored internally in the UE. A dedicated test message RESET UE POSITIONING STORED INFORMATION has been defined in TS 34.109 8 clause 5.4 for the purpose of deleting this information. The measurements for n MBS beacons, enabled across the slots of an MBS transmission period 7
43、, shall be available at the UE byMBS_measT , where MBS_measT can be expressed as: ocTTnceilPrMBS_TPMBS_meas)10/(10T += ms where MBS_measT is the total time for detecting and measuring n beacons is the elapsed time from the trigger of the measurement to the start of the first MBS transmission period
44、MBS_TPT is the MBS transmission period (1 second) ocTPris the processing time, an upper-bound for which can be given as slotMBSTnceil_)10/(10 where slotMBST_is the duration of a MBS slot (100 ms) with continuous MBS transmissions The last location request received by higher layers The last location

The test case req
47、uirements for MBS Measurement time can be found in clause A.3. 4.2.4 RRC states for MBS measurements For LTE, the minimum MBS performance requirements are specified in clause 5 for RRC_CONNECTED state. For UTRA, the minimum MBS performance requirements are specified in clause 5 for different RRC sta
48、tes that include Cell_DCH and Cell_FACH. 4.2.5 MBS Measurement Error Definitions The code phase measurement error is defined as the difference between the actual code phase for a given MBS beacon, and the estimated code phase for that beacon, as reported in the LPP message of type PROVIDE LOCATION I
49、NFORMATION for LTE 3, and the UE Positioning AddPos measured results IE in the MEASUREMENT REPORT ETSI ETSI TS 137 171 V13.1.0 (2017-01)83GPP TS 37.171 version 13.1.0 Release 13message for UTRA 6. This difference has to then be adjusted for the measurement bias introduced by the UE clock to provide the final code phase measurement error. 5 MBS minimum performance requirements 5.1 General The minimum performance requirements specified in clause 5 apply for UEs that support MBS.
