CTOnews.com August 19 news, today, at the second press conference of the "New era Industry and Information Development" series, Xu Bo, deputy director of the Radio Administration Bureau of the Ministry of Industry and Information Technology, said that in the follow-up, based on the current situation of the industry, the Ministry of Industry and Information Technology will issue a plan for the use of 5G millimeter wave frequency band in stages; and according to the needs of basic telecom operators, promote 2G, 3G to 5G frequency re-cultivation to improve the efficiency of spectrum resources.
According to reports, in terms of the supply of 5G frequency resources, China's 5G frequency management has always adhered to systematic thinking and long-term planning. Based on the supply chain situation of China's 5G industry chain and considering comprehensively the characteristics of high, medium and low frequency bands, the Ministry of Industry and Information Technology took the lead in issuing the frequency usage plan of the medium frequency band of the 5G system in 2017, and in December 2018, it granted 5G medium and low frequency band spectrum resources of at least continuous 100MHz bandwidth to three basic telecom operators respectively. As of July 2022, the Ministry of Industry and Information Technology has licensed 770MHz bandwidth 5G middle and low frequency band frequency resources for basic telecom operators, and the total number of licensed middle and low frequency band frequency resources ranks first in the world, accounting for 69.4% of all licensed public mobile communication frequency resources in China, effectively ensuring the frequency resources needed for China's 5G scale deployment and high-quality development, and promoting the maturity and development of China's middle and low frequency band 5G industry chain.
In terms of frequency use guarantee, because there are still some radio stations (stations) such as satellite earth stations legally set up and used in China on the same or adjacent frequencies of the 5G system in the intermediate frequency band, in order to ensure that 5G base stations do not affect the normal work of radio stations (stations) such as satellite earth stations, the Ministry of Industry and Information Technology has planned and coordinated the interference between 5G base stations and radio stations (stations) such as satellite earth stations in advance, and as of last month A total of 12779 radio stations (stations), such as affected satellite earth stations, have completed interference coordination or technical transformation, with a coordination rate of 99.91%, creating good conditions for the smooth large-scale deployment of 5G.
In terms of 5G radio equipment management, in order to meet the needs of 5G commercial deployment, the Ministry of Industry and Information Technology issued "2100MHz band 5G mobile communication system base station radio frequency technical requirements (trial)" and "5G system repeater radio frequency technical requirements (trial)" to ensure the compatible coexistence of 5G system and other radio service systems. Issue the Circular on strengthening and standardizing the Radio Management of 2400MHz, 5100MHz and 5800MHz bands to ensure that wireless LAN, Bluetooth, non-stop charging and other radio systems are compatible and shared with 5G, Beidou, car networking and other frequencies. In the follow-up, based on the current situation of the industry, the Ministry of Industry and Information Technology will issue a plan for the use of 5G millimeter wave frequency in stages; and according to the needs of basic telecom operators, it will promote the re-cultivation of 2G and 3G to 5G frequency to improve the efficiency of the use of spectrum resources. Internationally, under the framework of the International Telecommunication Union, the Ministry of Industry and Information Technology will strengthen bilateral and multilateral cooperation and exchanges with relevant countries and international organizations, coordinate the positions on key issues of the 2023 World Radiocommunication Conference (WRC-23), and continue to promote global or regional coordination of 5G / 6G frequency division in relevant frequency bands.
