19 China: announced 5G Frequency Planning on C bands Plan and as 5G frequency bands ( is limited to indoor scenario) June, 2017: Issued the spectrum consultation to the public on use of 5G system in C bands, including and November, 2017: Officially announced by MIIT, China Seek opinions on GHz, GHz, and other possible mmwave bands June, 2017: Issued the spectrum consultation to the public on use of 5G system in mmwave bands, including GHz, GHz and other millimeter-wave bands On-going: Sharing and compatibility studies in the key bands towards WRC-19 A.I On July 2017, the MIIT approved GHz, GHz and GHz band to be utilized as the spectrum of China's 5G R&D trial, in addition to GHz.

20 US: start with mmwave 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 : , , , 37-40, GHz ; 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. Sub-6 GHz T-Mobile plans to use its 600 spectrum to provide nationwide 5G rollout by 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 of 600 spectrum covering 328 million PoPs. Sprint holds more than 160 of 2.5 GHz spectrum(band 41) and aims to use this band to provide 5G. For the 3.5 GHz band ( in the US), adopt a three-tier scheme(incumbent users, Priority access license, General authorized access ) GHz:FCC intends to propose the next steps needed to make the GHz band available for 5G.

26 Compatibility &40GHz Several compatibility studies are carrying out in IMT-2020(5G) Promotion Group(China) based on the inputs from contributing WPs of WRC-19 Agenda Item IMT vs. Inter-Satellite Service (ISS), Earth Exploration-Satellite Service(EESS) and Fix Satellite band IMT vs. band IMT vs. & 37GHz bands IMT vs. ISS IMT vs. EESS/FSS 26&40GHz IMT vs. FSS 26GHz

27 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.
