Keysight Pitches In On 3GPP’s MIMO Over-The-Air Testing

July 26, 2020

Collaboration with CAICT results in first performance test case for benchmarking 5G MIMO devices in frequency range 1

Keysight Technologies has contributed to a technical report published by 3GPP on multiple-input, multiple-output (MIMO) over-the-air (OTA) testing that will help the wireless industry accelerate advanced 5G device performance validation. The company contributed more than 35 submissions to the technical report (TR) 38.827 officially approved by 3GPP on July 3rd. This technical report defines radiated metrics and test methodology for verifying multi-antenna reception performance of a user equipment (UE) such as a smartphone or other handheld device operating in frequency range 1 (FR1) or FR2.

Successful collaboration with the China Academy of Information and Communications Technology (CAICT) resulted in the first benchmarking of a 5G 4x4 MIMO device in FR1 using test procedures and channel models described in 3GPP TR 38.827 and Keysight's PROPSIM 5G channel emulator and UXM 5G wireless test platform.

This 3GPP milestone supports chipset and device makers in the process of verifying the performance 5G devices equipped with up to four antenna transmitters (4x4 MIMO). Keysight contributed by:

· Defining channel models for generating a valid test propagation environment and the evaluation of test methods for measuring the data throughput a device transmits.

· Defining MIMO OTA systems to ensure repeatability and stability in test results.

Keysight offers a wide range of test platforms for verifying 5G devices that use MIMO technology and high-performance antennas to the deliver superior data rates that advanced 5G applications rely on. Keysight's new Advanced Performance Test Toolset supports test cases specified by 3GPP for FR2 MIMO OTA testing, enabling an expanding ecosystem to validate 5G device performance under accurate and real-world conditions using 3D fading and mobility scenarios.
