FootnotesCurrent use

Bands having a worldwide (co)primary allocation to Mobile Servicehave most potential for spectrum designation

Not all bands with (co)primary allocation to Mobile Service may be suitable for IMT designationTherefore, detailed studies are needed to assess the suitability

22/10/20156 © Nokia 2015

Interference is key and the spectrum should be used as efficiently as is practical

Contiguous spectrum

E.g. Several hundreds of MHz of contiguous spectrum needed for a band to be suitable for Mobile Broadband

Channel bandwidth

Regulator-assigned channel bandwidths need to be assessed

ITU RR, etc Table footnotes should be examined to find out restrictions and prohibitions

Actual usage (not just allocation) of the frequency ranges should be further investigated

Channel characteristics

Channel/path loss model needs to be studied.

Current Nokia’s Views

For example:

Current activities should be focused to find ranges/bands to be studied between WRC-15 and WRC-19 (and not to find and decide on the bands to allocate)

Storyline

5G will need both cm and mm-wave spectrum. The exact amount of spectrum bandwidth requires study. Preliminary estimates based on projected 5G use case scenarios indicate that spectrum bandwidth per

22/10/20158 © Nokia 2014 - File Name - Version - Creator - DocID

be studied as wide as possible

Keep as many ranges alive as possible, especially below 30GHz

2-4 wide ranges in low (~6-20GHz), medium (~20-40GHz) and high (~40-90GHz) frequencies

5.925 – 8.5 GHz10.7 – 19.7 GHz24.25 – 29.5 GHz36 – 50.2 GHz66 – 71 GHz71 – 76 / 81 - 86 GHz

indicate that spectrum bandwidth per operator is likely to be something like:

~500MHz below 20GHz ~1GHz between 20-40GHz ~2 GHz above 40GHz.
