Recently, Huawei fellow Dr. Zhu Peiying was invited to deliver a speech with the theme of “endless frontier: from 5g to 5.5G” at the IEEE wcnc2021 (IEEE wireless communication and network conference) conference recently, calling on the industry interface to jointly launch 5.5G innovation and standardization towards 2025. Ieeewcnc is the world’s top academic conference of IEEE in the field of wireless. It brings together leading experts from academia and industry to discuss and promote the development of wireless communication and network related technologies.

Wireless is an endless frontier

Zhu Peiying said at the meeting, “as Dr. Vannevar Bush said, science is an endless frontier. What’s fascinating about wireless is that it always has endless opportunities for innovation. At present, the commercial deployment of 5g has begun to feed back and encourage the continuous innovation of 5g technology.

The speed of 5g business is beyond imagination. Compared with 2019, the number of commercial networks has increased by 18 times to more than 140; the types of terminals have increased by 17 times to more than 550; the number of 5g users has increased by 250 times to more than 250 million. 5g has also changed the consumer experience and industry digitization. The annual growth rate of AR / VR has reached 35%. The practice of more than 5000 industries such as 5g port and 5g steel has begun to take shape.

5g’s commercial achievements, as well as the development of new technologies in the industry, reveal us the new frontier of 5g. How to meet the growing demands of immersive experience such as xrpro and holography, and how to meet the more diverse and complex demands of Internet of things such as machine vision and Internet of vehicles are the questions to be answered in the evolution of 5g to 5.5G.

Facing 2025

Launch 5.5G definition and standardization

“The driving force of 5.5G has been clear: first, the existing capacity of 5g needs to continue to be enhanced to accelerate the development of 5g industry; second, the popularity of immersion applications such as XR and holography needs high-speed real-time experience; third, industry digitization needs ten times the uplink speed, and needs the network of behavior center; fourth, expand the dimension of 5g network capacity, and open up new business opportunities such as the Internet of vehicles,” Zhu Peiying said at the meeting It is shown that.

What will 5.5G look like? From the perspective of scenario, Huawei proposes to add UCBC (uplink ultra wideband), rtbc (broadband real-time interaction) and HCs (Communication perception fusion) three scenarios, which together with the traditional embB, mmtc and urllc form a 5.5G hexagon. Under these scenarios, Huawei expects 5.5G to achieve the following goals: the bit cost of embB will continue to be reduced by 10 times; the uplink capability of UCBC will be improved to meet the needs of 80% tob scenarios; rtbc will be able to provide services for dozens of XR users [email protected] It has the following advantages: low power consumption positioning capability in centimeter level to meet the needs of indoor full scene positioning; wide area high-resolution sensing capability to realize spatial location management and anomaly detection Detection, help to enhance the safety of automatic driving, timely care of the elderly patients in designated areas, etc.

It takes 3-5 years for new technology to advance from industry to standardization and mature supporting facilities. For example, uplink enhancement, in addition to the research of multi band uplink aggregation and uplink massive array technology, it also needs a lot of time to enrich the new terminal types of the uplink behavior center. From the spectrum point of view, 5.5G needs to use more resources in sub-100ghz, and it also needs time to prepare in advance from the policy and industry level. Aiming at 2025, Zhu Peiying called for the definition and standardization of 5.5G from now on, and continued to implement it in R18 and other subsequent versions.

For 2030

Start exploring the vision of a new generation

Communication technology keeps the evolution speed of one generation in ten years. Since the 1980s, through the innovation of four generations of communication technology, we have gradually realized “connecting everyone”. With the rapid commercialization of 5g technology, we are rapidly realizing “connecting everything”. Now, 5.5G has begun to explore from “interconnection of all things” to “intelligent connection of all things”.

How to define the vision of 6G after 2030? Zhu Peiying predicted, “in ten years’ time, intelligence will be everywhere. After 2030, the network will no longer be just a data transmission pipeline, but a distributed neural network that can integrate the biological world, physical world and digital world.

“For 2025 and even 2030, wireless is full of adventure ahead of us. Huawei hopes to explore the endless frontier of 5.5G and beyond with its partners, “said Zhu Peiying.
