Introduction ETSI ETSI TR 136 903 V12.8.0 (2016-01)63GPP TR 36.903 version 12.8.0 Release 121 Scope The present document specifies a general method used to derive Test Tolerances
25、for Radio Resource Management tests, and establishes a system for relating the Test Tolerances to the measurement uncertainties of the Test System. The test cases which have been analysed to determine Test Tolerances are included as .zip files. The present document is applicable from Release 8 up to
26、 the release indicated on the front page of the present Terminal conformance specifications. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication
27、, edition number, version number, etc.) or non-specific. For a specific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the
28、latest version of that document in the same Release as the present document unless the context in which the reference is made suggests a different Release is relevant (information on the applicable release in a particular context can be found in e.g. test case title, description or applicability, me

36、erposition For multi-cell tests there are several cells each generating various Physical channels. In general cells are combined along with AWGN, so the signal and noise seen by the UE may be determined by more than one cell. Since several cells may contribute towards the overall power applied to th
37、e UE, a number of test system uncertainties affect the signal and noise seen by the UE. The aim of the superposition method is to vary each controllable parameter of the test system separately, and to establish its effect on the critical parameters as seen by the UE receiver. The superposition princ
38、iple then allows the effect of each test system uncertainty to be added, to calculate the overall effect. The contributing test system uncertainties shall form a minimum set for the superposition principle to be applicable. 4.2 Sensitivity analysis A change in any one channel level or channel ratio
39、generated at source does not necessarily have a 1:1 effect at the UE. The effect of each controllable parameter of the test system on the critical parameters as seen by the UE receiver shall therefore be established. As a consequence of the sensitivity scaling factors not necessarily being unity, th
40、e test system uncertainties cannot be directly applied as test tolerances to the critical parameters as seen by the UE. EXAMPLE: In many of the tests described, the s / Iotis one of the critical parameters at the UE. Scaling factors are used to model the sensitivity of the s / Iotto each test system
41、 uncertainty. When the scaling factors have been determined, the superposition principle then allows the effect of each test system uncertainty to be added, to give the overall variability in the critical parameters as seen at the UE. There are often constraints on several parameters at the UE. The
42、aim of the sensitivity analysis, together with the acceptable test system uncertainties, is to ensure that the variability in each of these parameters is controlled within the limits necessary for the specification to apply. The test has then been conducted under valid conditions. 4.3 Statistical co
43、mbination of uncertainties The acceptable uncertainties of the test system are specified as the measurement uncertainty tolerance interval for a specific measurement that contains 95 % of the performance of a population of test equipment, in accordance with 3GPP TS 36.521-3 5 clause F.1. In the RRM
44、tests covered by the present document, the Test System shall enable the stimulus signals in the test case to be adjusted to within the specified range, with an uncertainty not exceeding the specified values. The method given in the present document combines the acceptable uncertainties of the test s
45、ystem, to give the overall variability in the critical parameters as seen at the UE. Since the process does not add any new uncertainties, the method of combination should be chosen to maintain the same tolerance interval for the combined uncertainty as is already specified for the contributing test
46、 system uncertainties. The basic principle for combining uncertainties is in accordance with ETR 273-1-2 2. In summary, the process requires 3 steps: ETSI ETSI TR 136 903 V12.8.0 (2016-01)83GPP TR 36.903 version 12.8.0 Release 12a) Express the value of each contributing uncertainty as a one standard
47、 deviation figure, from knowledge of its numeric value and its distribution. b) Combine all the one standard deviation figures as root-sum-squares, to give the one standard deviation value for the combined uncertainty. c) Expand the combined uncertainty by a coverage factor, according to the toleran
48、ce interval required. Provided that the contributing uncertainties have already been obtained using this method, using a coverage factor of 2, further stages of combination can be achieved by performing step b) alone, since steps a) and c) simply divide by 2 and multiply by 2 respectively. The root-
49、sum-squares method is therefore used to maintain the same tolerance interval for the combined uncertainty as is already specified for the contributing test system uncertainties. In some cases where correlation between contributing uncertainties has an adverse effect, the method is modified in accordance with clause 4.4.5 of the present document. In each analysis, the uncertainties are assumed to be uncorrelated, and are added result root-sum-square unless otherwise stated. The combination of uncertainties is performed using
