The present document examines several use cases with respective KPIs in different domains (e.g. inHome, SmartCities, SmartFarming, SmartFactories, Smart Energy, Public Safety, Logistics) and identifies new potential requirements for relays for energy efficiency and extensive coverage.
5G contemplates many different scenarios and verticals (inHome, SmartFarming, SmartFactories, Public Safety and others). Many of them are new while others have been already covered in earlier generations of mobile networks. What all of them have in common is that we can find use cases where more extensive coverage with good energy efficiency is needed in comparison to what earlier generations (3G, 4G) could offer.
Nevertheless, all these use cases present an heterogeneous set of performance requirements. While IoT use cases will address small data transmissions this is not the case for inHome scenarios where high bandwidth is expected. SmartFactories use cases have latency requirements that other use cases will not need.
The use of multi-hop relays will help to improve the coverage of the 5G system with good energy efficiency.
