China: announced 5G Frequency Planning on C bands
Plan 3300-3600 MHz and 4800-5000 MHz as 5G frequency bands
(3300-3400 MHz is limited to indoor scenario)
• June, 2017: Issued the spectrum consultation to the public on use of 5G system in C bands,
including 3300-3600 MHz and 4800-5000 MHz
• November, 2017: Officially announced by MIIT, China
Seek opinions on 24.75-27.5GHz, 37-42.5GHz, and other possible mmWave bands
• June, 2017: Issued the spectrum consultation to the public on use of 5G system in mmWave
bands , including 24.75-27.5GHz, 37-42.5GHz and other millimeter-wave bands
• On-going: Sharing and compatibility studies in the key bands towards WRC-19 A.I. 1.13
• On July 2017, the MIIT approved 4.8-5.0 GHz, 24.75-27.5 GHz and 37-42.5GHz band to be
utilized as the spectrum of China's 5G R&D trial, in addition to 3.4-3.6 GHz.
US: start with mmWave
• Jul. 2016, FCC adopted rules to facilitate next generation wireless
technologies
• Nov. 2017, FCC adopted a Second Report and Order in its Spectrum
Frontiers Proceeding
licensed spectrum : 24.25-24.45, 24.75-25.25, 27.5-28.35, 37-40,
47.2-48.2GHz ; Unlicensed spectrum:64-71GHz
FCC announced plans to hold an auction of spectrum in the 28 GHz
band in November 2018, followed immediately by an auction of
spectrum in the 24 GHz band.
• T-Mobile plans to use its 600 MHz spectrum to provide nationwide 5G rollout by 2020. This band provides wider-area
coverage compared to some of the higher frequency 5G bands. At the end of 2017, T-Mobile owned a nationwide average
of 31 MHz of 600 MHz spectrum covering 328 million PoPs.
mmWave
Sub-6 GHz
• Sprint holds more than 160 MHz of 2.5 GHz spectrum(Band 41) and aims to use this band to provide 5G.
• For the 3.5 GHz band (3550–3700 MHz in the US), adopt a three-tier scheme(Incumbent users, Priority access license,
General authorized access ).
• 3.7-4.2GHz:FCC intends to propose the next steps needed to make the 3.7–4.2 GHz band available for 5G.

Summary
• Low and middle frequency bands (below 6GHz) are core bands for 5G system, which enables
seamless wide area coverage capability and also applies to internet of things scenarios.
• High frequency bands (above 6GHz) are key supplemental bands for 5G system, which
enables high capacity for the system and backhaul.
• Global harmonization under the study in ITU WRC-19 AI.1.13 is important, the administrations
are currently focus on compatibility studies in 26GHz and 39GHz.
• International cooperation is important to promote global and regional harmonization of 5G
spectrum.
