At the 3GPP RAN#96 meeting held in Budapest, Hungary from June 6 to June 9, 3GPP officially defined the U6G (6GHz upper band, ie 6425-7125 MHz) as authorized spectrum, the frequency band number is n104, which clarified the corresponding network/terminal RF standards, and provided a standard basis for the subsequent industry chain research and development of 6GHz products.
At the same time, the conference passed a resolution to approve the Rel-18 project for the full 6GHz spectrum (5925MHz-7125MHz), which is a key milestone in the IMTization of the 6GHz spectrum.
If the mobile industry is the engine of national digital transformation,then mid-band spectrums as 6GHz are the fuel.
Mobile communication has become an important pillar of the national development strategies of countries around the world. Ensuring the sustainable development of the mobile industry is the key to supporting the digital transformation of the country. The Global System for Mobile Communications Association (GSMA) calls on each country to open at least 2GHz of mid-band spectrum between 2025 and 2030 to meet the 5G rate requirements set by the United Nations International Telecommunication Union (ITU).
6GHz (5925-7125MHz), as an important part of the intermediate frequency spectrum, can take into account the coverage advantages of low frequencies and the capacity advantages of high frequencies, popularize 5G large-bandwidth services at a lower cost per bit, and enable the continuous innovation and development of emerging 5G applications, to accelerate the process of social digital transformation.
In the next few years, 5G will continue to develop, bringing huge benefits to mobile services and users.
The use of 6GHz spectrum resources for 5G NR and subsequent evolution technologies is one of the key factors to ensure the economic feasibility and universal affordability of 5G services.
As an effective supplement to mid-band 5G, the 6GHz frequency band can well balance the coverage and capacity of this frequency band, and can achieve continuous allocation of hundreds of megahertz large-bandwidth spectrum to meet the demand for greater data traffic in the future; the planning of the 6GHz frequency band is conducive to the unified planning and use of global spectrum resources, and is favorable to the sustainable development of the mobile communication industry in the future.
Global collaboration in the mobile industry to accelerate 6 GHz standardization and ecological development
On December 17, 2021, the 3GPP RAN meeting decided to start the standardization of U6G as a new frequency band authorized by IMT.
After half a year, the U6G authorized new frequency band standardization work has been successfully completed, which is the result of the collaborative efforts of global telecom operators, network equipment manufacturers, terminal/chip/instrument manufacturers and other industrial partners. It shows the determination of the mobile industry to accelerate the promotion of U6G IMT.
In the future, the industry chain will develop U6G mobile network and terminal products according to the radio frequency standard defined by 3GPP, and promote the ecological improvement of 6GHz IMT.
At present, leading countries and operators have carried out 6GHz IMT field tests, and it is expected to achieve pre-commercial deployment of 6GHz IMT in 2025.
WRC-23: 6 GHz spectrum and U6G IMT global identification
The next World Radiocommunication Conference (WRC) will be held in 2023, which will be a valuable opportunity for governments to coordinate 6GHz spectrum strategies and discuss the development of the global telecommunications ecosystem.
The mobile industry has reached a preliminary consensus on the use of U6G for IMT.
As early as WRC-19, it was decided to set up the AI 1.2 topic to study U6G IMT logo for WRC-23. It is believed that more countries and regions will recognize the importance of 6GHz in the future, and to support the importance of sustainable development of the mobile industry and jointly promote the global U6G IMT logo, thereby accelerating the digital transformation process of various countries.
