Korea Mobile Broadband Plan
Corresponding to rapid increase of mobile data traffic
Additional bands of
1 GHz bandwidth by 2023
Securing 1190 MHz band-
width including bands
already allocated (390 MHz )

IMT bands below 6 GHz
Additional IMT bands
below 6 GHz -> WRC-15 AI 1.1
above 6 GHz -> WRC-19 AI
Discussion on IMT band below 5 GHz (WRC-15 AI 1.1)
Sharing studies and evaluation of availability
Sufficient bandwidths: wider than 10 MHz bandwidth
Service coverage: national or local
Global harmonization: channeling arrangements
Coordination with neighboring countries: harmonized use to
reduce mutual interferences
Easy relocation/re-farming: available bands for relocation, clearing
schedule and expenses
Support 3600-3800 MHz and 1452-1492 MHz

IMT bands above 6 GHz
Future Works for IMT to solve:
Congested use of incumbent services below 6GHz
Heavy traffic in dense urban area (e.g., ‘hot-spot’)
Demands on maximized efficiency of data delivery
IMT in the bands above 6 GHz with advantages:
Wide contagious bandwidth
Development of semiconductor technology
Facilitation of multi-beamforming in higher frequency
Tolerable path loss within small cells

5G Vision
Mobile Bands in the RR on a primary basis in 6-100 GHz
Stage 1: Mobile bands in all Regions on a primary basis
Stage 2: by additional allocation or upgrade to primary service
Exclude bands for passive services (Earth Exploration Satellite service or Radio
astronomy)
Exclude Planned bands for satellite service
Preferably, bands with less operating stations
Wide contiguous bandwidths (at least 500㎒ bandwidth)
Korea supports:
27-29.5 GHz, 31.8 - 33.4 GHz, 37 - 42.5 GHz, 45.5 - 52.6 GHz (Exclusion of 50.2
– 50.4 GHz), 66 - 74 GHz
Criteria for candidate band above 6GHz

1/1.1/4.1.10 Frequency bands within the range 5 350 - 5 470 MHz
Korea proposed WRC-19 AI to APG15-5
“ To consider identification to IMT in the frequency range between 27 ㎓ and 74 ㎓ including possible additional allocations to mobile service on a primary
service in accordance with Resolution YYY (WRC-15)”
APT common Proposal
“to consider identification of frequency bands for IMT including possible
additional allocations to the mobile service on a primary basis in accordance with
Resolution [ASP-B10- IMT_ABOVE_6GHz] (WRC-15)”
Resolution [ASP-B10- IMT_ABOVE_6GHz] (WRC-15) “Studies on frequency-
related matters for IMT identification including possible additional allocations to
the mobile services on a primary basis in portion(s) of the frequency range
between 25.25 and 86 GHz for the future development of IMT for 2020 and
beyond”
