ed to operate in this mode, the integration of unlicensed spectrum into 5G (i.e. NR-U) will make it more easily available to cellular operators. In general, we expect more 5G networks to be rolled out in RAN sharing mode than in 4G, and more neutral host cellular networks to become available with 5G rollout. Technical Requirements of 5G Radio Interfaces In order for a proposed radio interface to qualify as an IMT-2020 radio interface (and to make use of IMT-2020 identified spectrum), it has to fulfill certain technical require- ments specified in Recommendation ITU-R M.2083. According to M.2083, IMT-2020 applications would fall into the following three broad usage scenarios as illustrated in Figure 2.9: URLLC The eMBB use case addresses human-centric scenarios. It is essentially the natural evo- lution of the 4G mobile broadband, which is meant to deliver the same services, but with higher throughputs, lower latencies, better power efficiency, and lower cost.

The URLLC use case has stringent throughput, latency, and availability requirements. Its applications are under the early stages of development at the moment and it is perhaps the most ambitious goal of 5G. There is hardly anything equivalent as of now and it remains to be seen when future use cases, such as remote wireless control of industrial machinery, remote medical surgery, etc. actually emerge. And finally, there is the MTC use case, which is characterized by a very large number of devices transmitting low volumes o
