- Demonstration of training and operation of artificial
intelligence signal processing models inside a 6G physical
layer
- AI models are trained with simulated and real-world data
- Operation of models are validated in an over-the-air
system
Keysight Technologies, Inc. (NYSE: KEYS) has collaborated with
mobile, video and AI technology research and development company
InterDigital Inc. (Nasdaq: IDCC) to show how Artificial
Intelligence (AI) channel estimators can be trained, integrated
into a physical layer, and evaluated with an over-the-air
demonstration at Mobile World Congress Barcelona 2024 (MWC24).
Presented at Keysight's booth, Hall 5 Stand 5E12, the demonstration
will feature a 144 GHz communications link that uses AI models for
channel estimation developed by InterDigital and Keysight.
As AI technology matures, it is being integrated into wireless
communications systems and will be a foundational technology for
6G. One of the applications of AI in wireless is channel
estimation. When the channel estimation block is replaced with a
neural network (NN), site-specific training data used for the NN
can optimize its performance and robustness to new use cases.
The demonstration uses Keysight’s communications system-specific
Electronic Design Automation (EDA) software to model a 3GPP
physical layer and wireless channels. Instead of using the
traditional channel estimation signal processing, this block has
been replaced with various neural networks for channel estimation.
The first NN was fully developed and trained by InterDigital and
delivered to Keysight. The second NN was developed by Keysight and
trained in two different ways. First using a combination of data
generated by Keysight’s Electronic Design Automation System
(SystemVue) software and then again using real-world measurement
data. The demonstration compares performance and complexity of
InterDigital and Keysight’s Machine Learning approaches to that of
traditional channel estimation, and uses an EDA software
environment and a real-world 144 GHz over-the-air environment.
Being able to benchmark the performance of NN and compare them
to traditional methods as well as other NN is critical for the
advancement of AI in 6G. Without these sorts of measurements and
comparisons, the true performance gains (or losses) of AI cannot be
known and the adoption of the technology will be hindered.
Milind Kulkarni, Vice President and Head of Wireless Labs at
InterDigital, said: “Through partnership with Keysight,
we are able to extend our ability to validate AI solutions for
wireless networks. These types of collaborations and their outcomes
provide valuable insight and build industry alignment as we work to
shape how AI will be used in both 5G and 6G.”
Giampaolo Tardioli, Vice President, 6G and Next Generation
Technology at Keysight, said: “The world is embarking on a
transformative journey to revolutionize the future of connectivity
with the use of AI in wireless communications. Our collaboration
with strategic partners like InterDigital enables us to hone our
solutions and capabilities to meet the needs of our customers as
they continue pushing the boundaries of what is possible when AI
and wireless are combined.”
This demonstration includes technology that was developed as
part of CENTRIC and 6G-SANDBOX, projects that have received funding
from the Smart Networks and Services Joint Undertaking (SNS JU)
under the European Union's Horizon Europe research and innovation
program under Grant Agreement No 101096379 & 101096328
respectively.
