Abstract
Over-the-air (OTA) radiated testing of 5G new radio
(NR) at frequency range 2 (FR2) is seen mandatory due to integrated
radio frequency circuits and antenna design. Multiprobeanechoic
chamber (MPAC) solution is the reference method for
performance testing of FR2 NR in the standardization. One of
the key topics for the MPAC solution is channel validation. The
test zone size in wavelength is much larger for FR2 MPAC setups.
Furthermore, the far-field assumption will be violated due to the
compact MPAC system. Those new aspects have introduced new
challenges for the channel spatial profile validation in the test
zone. In this work, a generic channel spatial profile validation
method is numerically analyzed, with a focus on the the impact of
test zone radius, measurement distance error and spatial location
selection in the test zone on the channel spatial profile validation
results.
