Standardization Progress and Challenges for 5G OTA Testing

Precise evaluation of MIMO performance and communication capacity measurement are essential to guarantee 5G product development and advance the 5G industry. The main developments in 3GPP Multiple-input Multiple-output (MIMO) Over-the-Air (OTA) standards for FR1 (450MHz-7.125GHz) and FR2 (24.25GHz-52.6GHz) are described in this paper along with the test methodologies and performance metrics. Furthermore, it is demonstrated the handheld test scenarios are important to the current MIMO OTA performance testing. Results of the channel model validation for FR2 MIMO OTA measurements are presented in our 3D-MPAC, confirming the successful application of the channel model in the test zone.
