PoC #5: ICN transport for mmWave Networks (KDDI)
To resolve problems with intermittent connectivity in a mmWave network, Tokyo Tech, Sony, JRC and KDDI
Labs jointly developed a new wireless access network that combined 40 GHz operation for outdoor networks
with 60 GHz operation for mobiles to enable large data size content delivery on the gigabyte scale,

Using a future architecture technology called content centric networking (CCN) , KDDI Labs developed a
method that operates together with the mmWave small zone (60 GHz band) and large zone long-term
evolution (LTE) schemes in HetNets (KDDI Labs 2015). We could therefore realize high-speed file transfer in
the mmWave band without the user being aware of switching of bands when passing through the GATE
system.

Table 1 lists the 2015 Gaps (ITU 2015) and matches them to this year’s PoCs and other related publications.
All the PoCs addressed the topic of using ICN in IMT-2020 to delivery user services. They also all addressed
mobility and routing, as those are areas where ICN could delivery significant improvements compared to the
current anchored mobility in LTE. Only one publication (Suthar 2016) addressed the technical challenges of
adapting 3GPP signalling to ICN. Some other topics, E.4, E.7, E.10, E.11, E.14 and E.15 did not receive any
attention. Overall, the PoCs and two publications addressed 9 of the 15 gaps.
1 CCN is a future protocol that is currently being discussed by the Internet Research Task Force (IRTF) as a replacement
for the Internet Protocol (IP).
