O.2.5 Reference AUT positions
38.521-23GPPNRPart 2: Range 2 StandaloneRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
The reference AUT shall be positioned in a total of 7 different reference positions, shown in Figure O.2.5.1-1 and O.2.5.2-1
While position 1, P1, is the centre of the quiet zone, the remaining positions, 2 through 7, are off-centre positions each displaced by the radius of the quiet zone, R. The coordinates of the respective test points are shown in Table O.2.5-1.

For quiet zones exceeding 30cm in diameter, i.e., R=20cm and R=27.5cm, an alternate set of reference points can be selected for the quality of quiet zone evaluation, summarized in Table O.2.5-2

Note: z6 and z7 are the maximum declared DUT heights in ±z defined in the chamber specification and are bound to a minimum of 15cm. The DUT antennas (grey-box approach)/the DUT (black box approach) cannot extend past these heights within the QZ (in z) when installed in the system. |
