Keysight, NTT DOCOMO, NTT Advance 6G Simulation and Distributed MIMO
Key Highlights
- The collaboration is incorporating real-world radio propagation measurements, including channel impulse response (CIR) data, to improve the accuracy of wireless channel models used in laboratory simulations.
- Keysight and NTT are developing simulation approaches for distributed MIMO architectures, where geographically dispersed antennas cooperate to enhance network coverage, capacity, and reliability.
- By combining high-fidelity channel models with advanced ray-based propagation techniques, the teams aim to create more scalable and repeatable methods for evaluating future 6G network concepts.
Keysight Technologies is collaborating with NTT DOCOMO and NTT to advance realistic 6G channel modeling and wireless communication simulation, supporting the industry's efforts to evaluate next-generation network architectures before deployment. The work builds on an existing memorandum of understanding (MoU) among the companies focused on 6G design, testing, and measurement technologies.
The collaboration has already produced initial progress in two key areas: measurement-driven channel modeling and distributed Multiple-Input Multiple-Output (MIMO) simulation. Together, these developments are intended to provide researchers with more accurate and repeatable methods for assessing emerging 6G concepts.
As 6G research accelerates, understanding wireless performance in real-world environments has become increasingly important. Urban landscapes, indoor venues, transportation corridors, and other complex settings present significant challenges for network evaluation. While field testing offers valuable insights, it can be costly, time-consuming, and difficult to replicate. Laboratory-based simulations, meanwhile, often struggle to capture the full range of radio propagation effects that influence beamforming, mobility, coverage, and reliability.
To address these challenges, Keysight and NTT DOCOMO are enhancing channel models using real-world radio propagation measurements, including channel impulse response (CIR) data. The goal is to create more realistic representations of complex environments within laboratory simulation platforms.
At the same time, Keysight and NTT are advancing simulation-based evaluation methods for distributed MIMO architectures, in which geographically distributed antennas work together to improve network coverage, capacity, and reliability. By combining high-fidelity channel models with advanced ray-based propagation techniques, the companies aim to enable scalable and repeatable assessments of future 6G network designs.
