O.3.3 Reference measurements
38.521-23GPPNRPart 2: Range 2 StandaloneRadio transmission and receptionRelease 17TSUser Equipment (UE) conformance specification
The spurious emissions quality of the quiet zone measurements shall use 3D pattern measurements of the reference antenna patterns as they most closely resemble the 3D/spherical surface measurements/integrals of EIRP. Therefore, the quality of the quiet zone measurements for TRP metrics shall be based on efficiency measurements.
The grid types for the TRP measurements shall meet the 0.25 dB maximum standard uncertainty. The min number of grid points for the two grid types are:
– 192 grid points for the constant step-size measurement grids
– 100 grid points for the constant density measurement grids (charged particle implementation)
