In keeping with the rapid growth in the global digital economy, Huawei is focusing on three core areas of fundamental theories, architecture, and software to support the long-term sustainable development of the ICT industry, according to Guo Ping, Rotating Chairman, Huawei. 

"Huawei is significantly increasing its strategic investment into foundational technologies. We are working with our partners to reshape our technological paradigm. Currently, we are reshaping three areas: fundamental theories, architecture, and software. This will support long-term, sustainable development of the ICT industry," says Guo Ping in his speech at Mobile World Congress (MWC) 2022.
Even as the global digital economy continues to surge at an unprecedented pace, with more than 50% of the worldwide GDP likely to be digitalized in 2022, the ICT is fast approaching the limits of the Shannon theorem. There is a need to explore new theories and architectures to ensure digital sustainability. 
Huawei launched its GUIDE business blueprint, which aims to help operators develop the five key capabilities required for business success: expanding services, innovating efficiently, leveraging resources, competing on value, and contributing to society.
Guo Ping also highlighted the sustainability challenges faced by the world and the industry. While digitalization will result in increased carbon emissions, the ICT industry can play a crucial role in helping other sectors bring down their carbon footprints ten times larger than its own footprint.  
The problem of channel capacity 
Huawei is exploring various technologies, including next-generation Massive Multiple Input Multiple Output (MIMO) and wireless intelligence, to take the capacity closer to the Shannon Limit. 
"At the same time, we are studying new theories like semantic communications to build on Shannon’s work. This will create new horizons for development within the communications industry," elaborated Guo Ping. 
Reshaping network architecture
The company is also exploring several options to reimagine network architecture to address technological challenges, including the need to achieve high-frequency, ultra-large bandwidth and ultra-high-speed wireless communications. 
"We are proactively exploring new technologies to reshape architecture. For example, we are integrating photonic and electronic technologies to solve key problems and the technique bottlenecks facing chips. A second example is radio-over-fiber. This ultra-broadband technology is used to reshape the architecture of small cells to ensure continued evolution," elaborates Guo Ping.
The service providers also need to rethink computing architecture. With the growing developments in intelligence and Big Data, the traditional CPU-centered computing architectures are not enough to address the growing demand. Huawei is working on designing peer-to-peer architectures that leverage the full potential of GPUs and NPUs to support global development of intelligence. 
The Software Rethink
The communications networks are moving from being hardware-centric to using software to scale easily and be more agile, flexible and programmable. Further, the growing intelligence ecosystem and development demands increase in computing capacity.
"In response, we have launched a plan to massively improve software performance and refactor software. We have already managed to double the performance of key indicators, like the number of wireless cells and scheduled users," says Guo Ping. 
Huawei is planning to leverage HarmonyOS and EulerOS for more effective use of the computing power available in different types of hardware. It will also use its Mindspore framework to help scientists and engineers improve development efficiency. Guo Ping highlighted that intelligent full-stack software refactoring is likely to create new opportunities. 
Huawei is at the forefront of investing in new technology approaches to address the challenges and to enable service providers to gain new efficiencies. As a result, it is second on the 2021 EU Industrial R&D Investment Scoreboard. It will continue to invest more in further optimizing system architecture and improving software performance. 
"By overcoming technique and technological challenges, we hope to build a highly reliable and trustworthy supply chain. We realize that great user experience comes from software-hardware synergies," says Guo Ping. 
Reducing carbon emissions by adopting the philosophy of `more bits, less watts’   
There is an urgency in all business verticals to adopt sustainable practices to address the issue of climate change. 
Huawei has already committed to making its products and solutions 2.7 times more energy efficient. The company’s "more bits, less watts" approach is helping it come up with new and innovative technology approaches to drive sustainable practices. 
Commenting on the geopolitical challenges being faced by the company in several international markets, Guo Ping said, "We are committed to helping our customers who choose us to achieve the greatest business success. We will continue our globalization strategy in standards, talent, supply chain, and more. We will continue to be active participants in global events."
Huawei calls on more industry partners to join its GUIDE blueprint, deeply integrate green and intelligent technologies, promote the interlocking between business value and technological value, and create a promising future.
