摘要

Abstract

Millimeter-wave (mmWave) communication is regarded as the key enabling component for fifth-generation (5G) cellular systems due to the large available spectrum bandwidth. To make mmWave new radio (NR) a reality

tremendous efforts have been exerted from the industry and academia. Performance evaluation of mmWave NR is a mandatory step and the key to ensuring the success of mmWave 5G deployment. Over-the-air (OTA) radiated method of testing mmWave NR in laboratory conditions is highly attractive

since it facilitates virtual field testing of mmWave devices in realistic propagation conditions. In this paper

we first discuss the need for and challenges in OTA measurement of mmWave 5G NR under fading channel conditions. After that

two promising candidate solutions

i.e.

wireless cable and multi-probe anechoic chamber (MPAC)

are detailed. Their principles

applicability for mmWave NR

and main challenges are discussed. Furthermore

preliminary experimental validation results in a frequency range 2 anechoic chamber are demonstrated for the wireless cable and MPAC methods at 28 GHz.
