When 5g construction is in full swing in major countries around the world, international standardization organizations represented by ITU, 3GPP and IEEE, as well as countries and regions such as EU, China, the United States, Japan and South Korea have prospectively launched the exploration of 6G technology.

Recently, Ericsson announced on its official website that it has joined the reindeer project, a 6G research project funded by the European Union, and will play a key role in it. Led by the multi antenna technology leaders alliance, the project brings together companies and scholars in the antenna field to jointly develop a new intelligent connection platform based on multi antenna, which is a technology crucial to the future 6G system.

The upgrading and evolution of mobile communication technology is driven by some specific technologies. In the 4G and 5g era, with the increase of spectrum, technology and battery performance, multi antenna technology is becoming more and more important, especially in the 5g millimeter wave scene, which plays a key role in improving network speed.

In the 6G era, it can be predicted that the frequency band used will further rise, which lays a foundation for the upgrading and large-scale use of multi antenna technology. Therefore, in the future 6G scenario, the antenna will further develop in the direction of smaller volume, simpler, lower power consumption and more integration.

This shows the importance of multi antenna technology in the 6G era.

The new multi antenna intelligent connection platform in the reindeer project consists of distributed radio, computing and storage structures. It will promote large-scale intelligent surfaces and cell free wireless access, so as to provide far more capacity than 5g networks in the future. It is expected that this will provide the ability to scale to quasi infinite capacity, realize zero latency perception and interact with a large number of embedded devices.

Ericsson attaches great importance to the R & D of the project. Magnusfrodigh, vice president and head of Ericsson Research Center, said: “the reindeer project provides an early symbol for the development of the next generation wireless system. Together with our partners, we will take important steps in 6G key technology areas such as cellular free wireless access and large-scale intelligent surface. “

“Reindeer project” is a 5gppp project, which is part of the EU horizon 2020 research and innovation plan. The project will start on January 1, 2021 and will run for three and a half years.

In the global mobile communication competition, the EU is a very important force. In the 3G and 4G era, the EU not only has an important voice in technical standards, but also leads the world in business. In the 5g era, the EU lags behind in business. For 6G research, as early as 2017, the EU launched a consultation on 6G technology R & D projects; In September 2020, a three-year 6G basic technology research project was launched, and several terahertz R & D projects were also launched.

The launch of several projects and the joining of heavy manufacturers such as Ericsson indicate that the EU has taken a certain lead in the 6G field.
