METIS 5G Concept

50

A user-centric 5G system concept that efficiently integrates: the support of MMC and URC,

the support of scalable data rates including very high data rates,

the support of scalable data rates including very low latencies,

for service provision to both consumers and devices/machines.

The system that fulfils these requirements be flexible to provide different services at different times. The system architecture must provide native support for extreme

Mobile Broadband (MBB) communication, MMC, URC, D2D, MN, and UDN.
