Recently, Xu Wenwei, Director of Huawei and Dean of the Strategic Research Institute, was invited to give a speech on the theme of “The Future Vision of the Internet of Everything” at the IEEE GLOBECOM 2020 conference. The IEEE GLOBECOM Annual Meeting is one of the two flagship conferences of IEEE (Institute of Electrical and Electronics Engineers).
Xu Wenwei said at the meeting: “5.5G is the next vision of the wireless communication industry to meet the needs of everything from the Internet of Everything to the Intelligent Connection of Everything”, and called for adherence to academic diversity and openness, and continued openness and upgrades, scientific research upgrades, and cooperation upgrades. Industry, academia, and research institutions continue to work together to promote the invention of fundamental technologies and breakthroughs in fundamental theories.

5.5G is the next step for the wireless communication industry
The development of 5G depends on investment in the short term, ecology in the medium term, and technological evolution in the long term. In the process of rapid and large-scale commercial use of 5G, the application and needs of industries and vertical industries promote the further upgrade and expansion of 5G, providing more abundant connection types and higher connection quality, and “bringing human society from the Internet of Everything to the Intelligent Connection of Everything”.
“5.5G is the next step in the wireless communication industry,” said Xu Wenwei. The 5.5G vision is an enhancement and expansion of 5G scenarios. The first is to continue to enhance the three standard scenarios of eMBB, mMTC and URLLC defined by ITU. Then 5.5G will expand three new scenarios, including uplink ultra-broadband UCBC (Uplink Centric Broadband Communication), broadband real-time interactive RTBC (Real-time Broadband Communication), and HCS (Harmonized Communication and Sensing). “Triangles” become richer “hexagons”.
Xu Wenwei also elaborated on the three technical demands of 5.5G development, “5.5G comes from 5G and needs to be compatible with all 5G devices; 5.5G needs to realize flexible use of sub-100GHz full frequency band on demand; 5.5G needs to be deeply integrated with AI to realize Air Interface+AI, Network+AI, Service+AI, to meet the demands of network diversity and energy consumption management.”
Meet new challenges and push the limits of theoretical frameworks
By 2030, the demand for AI will drive a 20-fold increase in connection speed and a nearly 100-fold increase in computing power. How to continuously improve connectivity and computing power is a challenge. In addition, as digital transformation accelerates, data center expansion and network deployments grow, power conservation and carbon neutrality are also pressing issues facing the communications industry.
Xu Wenwei said, “Breaking the limit of the theoretical framework, transmitting more information under limited bandwidth; processing data in a more efficient way, and improving computing and connection efficiency. To meet these new challenges requires new theories and the establishment of corresponding Mathematical foundations. We are already seeing the potential of new technologies like semantic propagation, AI federated learning, approximate computing.”
Semantic communication theory is a 70-year-old dream, an emerging field enabled by machine learning. Once the “Shannon Theory” of semantic communication is established, it will be possible to transmit massive amounts of information through a small number of bits. AI federated learning can distribute algorithm training to a large number of nodes to achieve higher performance, and AI federated learning does not need to transmit local data, which can protect data privacy. With the use of 5G, the further integration of communication and computing, AI federated learning will become more mature. Approximate computing is a new direction for balancing power consumption and performance. It adopts a different design concept from traditional computing and can balance precision and approximation to improve energy efficiency.
Promote breakthroughs in basic technologies and invention of basic theories with academic diversity and openness
Connectivity is the cornerstone of ICT and its power can never be overestimated. Today, we are so dependent on connections that they transcend geographic and spatial boundaries, becoming a necessity of our daily lives and the vein of our society. The future of the Internet of Everything requires us to jointly cultivate and promote the development of 5.5G and other technologies through the cooperation of industry, academia and research.
Diversity and openness have always been the driving force for technological progress. We need to continue to adhere to the academic spirit of openness and diversity, build and share a digital social ecosystem, seize the opportunities of digital transformation, and jointly build an intelligent world.
