China Announces New Ways To Coordinate The Resolution Of 5G Band Base Stations And Other Radio Stations

- Jan 04, 2019-

In order to ensure the development of the 5G frequency band, the Ministry of Industry and Information Technology of China has issued the “Measures for the Coordination of Radio Station Interference Coordination for the Fifth Generation Mobile Communication Base Stations and Satellite Earth Stations in the 3000-5000MHz Band” to coordinate the resolution of other radios such as 5G base stations and satellite earth stations. Taiwan's interference problem, standard and coordinated management methods.


It clarifies the interference coordination rules: after obtaining the medium-band 5G frequency use license, it should promptly know the information that needs interference protection from the local radio management agency; before launching the application and setting up the 5G relay station, it should initiate the use of the satellite with the unit. Coordination of interference and timely submission of coordination requests to local radio regulatory agencies. After receiving the coordination request, the unit and user who set up and use the satellite shall confirm it within 15 working days. If the two parties fail to reach an agreement on the coordination issue within 2 months, they can submit a request for assistance to the radio regulatory agency. After the coordination work is completed, the radio management agency may apply for a 5G relay station to set up a license.

It pointed out that the costs incurred by various measures taken to avoid interference with the above-mentioned satellite earth stations were in principle set by the 5G repeater in the 3400-3600 MHz band and borne by the user. In accordance with the principle of post-use, in the cities where


the 5G frequency band has been opened, the newly applied units that use satellites should complete 

the interference coordination with the 5G relay stations that have obtained the station licenses in the interference coordination area, and coordinate the time limit requirements with the satellites. The coordination is initiated in the same situation and the radio regulatory agency may be requested to assist if necessary. The cost incurred by taking measures to avoid interference from 5G relay stations shall, in principle, be borne by the satellite installation and use unit.


It is understood that at the beginning of this month, the Ministry of Industry and Information Technology issued the 5G low-frequency test frequency license to China Telecom, China Mobile and China Unicom. Among them, China Telecom and China Unicom obtained the test frequency license for the 3500MHz band, and China Mobile obtained the test frequency license for the 2600MHz and 4900MHz bands.
