Introduction ETSI ETSI TR 136 903 V13.0.0 (2017-01)63GPP TR 36.903 version 13.0.0 Release 131 Scope The present document specifies a general method used to derive Test Tolerances for Radio Reso
25、urce 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 the release i
26、ndicated 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, edition numb

36、 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 the UE, a number
37、 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 principle then allo
38、ws 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 generated at s
39、ource 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, the test system
40、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 uncertainty.
41、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 aim of the sen
42、sitivity 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 combination of u
43、ncertainties 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 tests covered
44、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 system, to give
45、 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 system uncert
46、ainties. 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 V13.0.0 (2017-01)83GPP TR 36.903 version 13.0.0 Release 13a) Express the value of each contributing uncertainty as a one standard deviation fig
47、ure, 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 tolerance interval re
48、quired. 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-sum-squares me
49、thod 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 dB values for
