The release of the notice further standardizes the relevant license change procedures that enterprises need to perform during 5g frequency sharing, defines the circumstances where license changes are not required, and fully ensures that enterprises use frequency resources in accordance with the law in 5g co construction and sharing, Further improve the frequency use efficiency and comprehensive benefits. Q: what is the main content of the notice? A: the main contents of the notice include: first, it defines two types of frequency sharing: 5g base station frequency sharing and user terminal frequency sharing. The second is to clarify the application materials and relevant approval requirements to be submitted for 5g base station frequency sharing and user terminal frequency sharing. The third is to clarify the requirements for handling the radio station license in the case of 5g base station frequency sharing. Fourth, the requirements for frequency utilization, interference coordination, frequency occupancy fee payment, supervision and inspection of 5g base station frequency sharing are clarified. Fifth, the requirements for terminating the frequency sharing of 5g base stations are clarified. Sixth, it is clear that basic telecom operators should abide by the relevant provisions of telecom business license when carrying out frequency sharing. Seventh, it puts forward management requirements for frequency sharing of public mobile communication systems of other technical systems. Q: what help has the release of the notice provided for enterprises to carry out 5g frequency sharing?

For the frequency sharing of user terminals, the notice specifies that enterprises do not need to handle license changes according to law, reducing the burden of enterprises; For base station frequency sharing, the notice further standardizes the relevant procedural requirements for enterprises to handle matters such as changing radio frequency use license and base station radio license according to law, which helps enterprises know the materials and relevant procedures required for base station frequency sharing. Q: what materials do enterprises need to submit to apply for 5g base station frequency sharing and user terminal frequency sharing? A: for basic telecom operators who plan to carry out base station frequency sharing, they should apply to the National Radio Administration for handling the radio frequency use license change procedures, and submit an agreement on base station frequency sharing. The agreement shall specify the specific frequency range of base station frequency sharing, rights and obligations of all parties, sharing region, sharing period, enterprise subject applying for 5g base station radio station license, sharing proportion of frequency occupation fee, conditions for terminating frequency sharing, etc. In addition, after obtaining the license to change the use of 5g frequency, the enterprise shall apply to the local radio management organization for handling the procedures for changing the license of 5g base station radio station. For the basic telecommunication operation enterprises that intend to carry out user terminal frequency sharing, they shall jointly submit written explanatory materials to the national radio administration to clarify the specific frequency range, sharing region, sharing period, sharing termination conditions and other matters involved in user terminal frequency sharing.
