Massive MIMO O-RAN Radio Units (O-RU): Design & Conformance Test Challenges

This joint presentation provides an overview of the design and conformance test challenges of massive MIMO and beamforming-capable O-RAN Radio Units, based on the collaborative R&D efforts and learnings from the recent O-RAN plugfests. 

Radio units are part of disaggregated 5G NR gNBs, we will review emerging O-RAN and 3GPP conformance test requirements and challenges from a CUSM-plane (Control, User, Synchronization, Management) point of view, and the implications on next generation test methodologies.  

Key learnings:

  • Design considerations applicable to testing massive MIMO radios with beamforming capabilities
  • 3GPP and O-RAN requirements for conformance testing
  • Define test methodology and setup for measurement and validation of features (KPIs)
